The present invention relates to heat exchangers and air-conditioning device.

In the past, there is known following heat exchangers: with multiple flat tubes, the fin that is engaged with multiple flat tubes and The collector linked with the end of multiple flat tubes makes the refrigerant in the internal flow of flat tube and the flows outside in flat tube Air carry out heat exchange.

For example, utilizing water in the heat exchanger documented by patent document 1 (Japanese Unexamined Patent Publication 2015-127618 bulletin) Space in collector is separated into upper space and lower space by the partition member of flat extension, and in partition member setting It rises and uses nozzle, refrigerant is made to substantially arrive at the flat tube connecting with the region of the top of upper space as a result,.

Subject to be solved by the invention

But in the heat exchanger documented by the patent document 1, the not only upper space in collector, in lower space Also it is connected with flat tube.

Here, it not will receive the pressure loss of rising nozzle with space, that is, lower space before nozzle by rising, Therefore, pressure is easy higher than upper space, and refrigerant is easy intensively to flow to the flat tube connecting with lower space.

Therefore, in the refrigerant flow in flat tube being connect with upper space and the flat tube being connect with lower space Refrigerant flow is different, it is possible to create the bias current of refrigerant.

In view of this, it is also contemplated that make as far as possible multiple flat tubes the top of rising nozzle connect with collector and eliminate or The flat tube that refrigerant intensively flows is reduced still to be supplied to from the outside of collector via refrigerant piping in refrigerant In the case where rising the space with the lower section of nozzle, need to be not connected to flat tube or reduction in the space for being connected with the refrigerant piping The flat tube to be connected.Therefore, when to connect the flat tube of identical quantity, heat exchanger is enlarged in the up-down direction, when When avoiding the enlargement of up and down direction, it is desirable to reduce the radical of the flat tube connected and reduce ability.

The present invention has been made in view of the above-described circumstances, and the issue of the present invention is to provide following heat exchanger and air-conditionings Device: also can fully guide refrigerant to the flat tube being located above, and avoid enlargement and the reduction of ability, and And the bias current of the refrigerant between multiple flat tubes is suppressed to smaller.

Means for solving the problems

The heat exchanger of 1st viewpoint has collector, multiple flat tubes, refrigerant piping and spray nozzle part.Multiple flat tube edges Collector length direction be arranged side by side.Collector is connected with multiple flat tubes.Importing space in refrigerant piping and collector connects It connects.Spray nozzle part is in the case where heat exchanger is used as evaporator, for refrigerant to be passed out to the length in collector from space is imported Spend supply space adjacent with space is imported on direction.Spray nozzle part is located at the position that flat tube side is more leaned on than refrigerant piping.It leads Enter space to be configured to, compared with the space of the connecting side of refrigerant piping, the space of flat tube side is in collector locating for spray nozzle part Length direction on interval it is narrower.

Flat tube is not particularly limited, for example, it is also possible to be formed with multiple streams side by side on the length direction of flowing path section Road.

In the heat exchanger, refrigerant is passed out into supply space from space is imported by spray nozzle part, thereby, it is possible to right Refrigerant is also fully supplied with importing the adjacent space flat tube that i.e. supply space connects in space in collector.

In addition, outside collector via refrigerant piping supply refrigerant in the case where, import space be also configured to The space of the connecting side of refrigerant piping is compared, interval of the space of the importing space side of spray nozzle part on the length direction of collector It is narrower.Therefore, the radical for the flat tube connecting with the importing space for use by the refrigerant flowing before spray nozzle part can be pressed down It is made as less.Thereby, it is possible to make the flat tube connecting with collector be located at the supply space side of spray nozzle part as much as possible, can eliminate Or reduce the flat tube connecting with the space for being easy to get higher by the pressure before spray nozzle part.Therefore, it can eliminate or reduce refrigeration The bias current of refrigerant between multiple flat tubes can be suppressed to smaller by the flat tube that agent is intensively flowed.

Furthermore it is possible to by interval of the space on the length direction of collector of the spray nozzle part side imported in space be configured compared with It is narrow, therefore, the less flat tube of bias current can be connected with enough radicals in the space of supply space side relative to spray nozzle part.By This, can by order to inhibit bias current and eliminate with import the flat tube that space connect in the case where or reduce and connect with importing space Flat tube in the case where the reduction of ability be suppressed to smaller, and inhibit heat exchanger large-scale on the length direction of collector Change.

As described above, refrigerant also can fully be guided to the flat tube connecting with the supply space of collector, and Inhibit enlargement and the reduction of ability, the bias current of the refrigerant between multiple flat tubes is suppressed to smaller.

The heat exchanger of 2nd viewpoint in the heat exchanger of the 1st viewpoint, multiple flat tubes only with the supply space in collector Connection.

In the heat exchanger, multiple flat tubes are only connect with the supply space in collector, are not connect with importing space.Cause This, there is no the flat tube being connect with by the higher space of pressure ratio before spray nozzle part, each flat tube equally with pass through Space connection after spray nozzle part.The flat tube intensively flowed thereby, it is possible to eliminate refrigerant, sufficiently inhibit multiple flat tubes it Between bias current.

The heat exchanger of 3rd viewpoint imports the spray nozzle part institute in space in the heat exchanger of the 1st viewpoint or the 2nd viewpoint The space of the flat tube side at place than refrigerant piping and imports at the connecting portion in space at the interval on the length direction of collector The interval on the length direction of collector it is narrow.

As the example of this construction, it is not particularly limited, still, such as enumerate following situation etc.: in multiple flat tubes In the case where separating defined interval configuration along the length direction of collector, the interval is narrower than the outer diameter of refrigerant piping.

In the heat exchanger, from outside collector via refrigerant piping supply refrigerant, import space in setting Have in the construction narrower than the width of refrigerant piping at the interval on the length direction of collector at the part of spray nozzle part, imports empty Between be also configured to be provided with length of the space in collector of the side of spray nozzle part compared with the space of the connecting side of refrigerant piping Interval on direction is narrower, therefore, is able to suppress the drop of the bias current of the refrigerant of flat tube, the enlargement of heat exchanger and ability It is low, and refrigerant piping can be connected to and import space.

For the heat exchanger of 4th viewpoint in the heat exchanger of the 3rd viewpoint, refrigerant piping is the piping of cylindrical shape.

In the heat exchanger, refrigerant piping is cylindrical shape, therefore, can improve resistance to pressure by easy shape Degree.Moreover, in the case where using the refrigerant piping of cylindrical shape in this way, for example, matching with using the refrigerant of flat pattern The case where pipe, is compared, it is difficult to constriction realize identical flow path area in the case where collector length direction on interval, collector Interval on length direction is easy to broaden.Interval on the length direction in this way using collector is easy the cylindrical shape to broaden In the case where refrigerant piping, also it is configured to compared with the outer diameter of the refrigerant piping of cylindrical shape, imports the setting in space Have interval of the side of spray nozzle part on the length direction of collector narrower, therefore, be able to suppress the refrigerant of flat tube bias current, The enlargement of heat exchanger and the reduction of ability.

The heat exchanger of 5th viewpoint also has in the heat exchanger of any one viewpoint in the 1st viewpoint~the 4th viewpoint There are the 1st division and the 1st guide part.Spray nozzle part is formed in the 1st division.1st division will be drawn in flat tube side in collector It is divided into and imports space and supply space.1st guide part is set to the side opposite with flat tube side of the 1st division, with Towards the side opposite with flat tube side and continuously or the stage be located at supply space side mode stretch.

Alternatively, it is also possible to the position penetrated through on the length direction that the 1st division is formed in collector, thus nozzle is set Portion.

In addition, the 1st division is also configured to the plate in the planar extension orthogonal with the length direction of collector.

In the heat exchanger, even if the side opposite with flat tube side in the 1st guide part is in the length direction of collector On position be located at the end than the importing space side in spray nozzle part on the length direction of collector more by supplying space side, the 1 guide part will imported into via refrigerant piping also by way of the part of the importing space side in the 1st guide part and import in space Refrigerant guide to, with the opposite side in supply space side, thereby, it is possible to be sent to be formed in the 1st on the length direction of collector The importing space side of the nozzle of division.Therefore, though the side opposite with flat tube side in the 1st guide part collector length Spend direction on position be located at than spray nozzle part importing space side end more by supply space side, also can be to the importing of nozzle Space side conveys refrigerant, also, the length direction in collector by making the space segment of the flat tube side imported in space On supply space side end position be in the opposite side in supply space side, be able to suppress flat tube and import space Connection.

In addition, the 1st guide part with the direction side opposite with flat tube side on the length direction of collector to be located at The mode of supply space side stretches, and therefore, can make and import the length direction in collector for the refrigerant piping that space connects On supply space side end position more by supply space side.

In addition, in the heat exchanger, be also possible to import the end of the supply space side in space by the 1st division and 1st guide part is constituted, and imports the end of the side opposite with supply space side in space by with orthogonal with the length direction of collector The flat part that extends of mode constitute.In the case where using flat part in this way, in used refrigerant piping and importing The end of the side of space connection in the case where the wider width on the length direction of collector, refrigerant piping with import it is empty Between the end of the supply space side on the length direction of collector of the end of side that connects be easy more by supply space side, example Such as, the ratio spray nozzle part sometimes and in multiple flat tubes more by supply space side and the flat tube nearest from spray nozzle part in collector The end of importing space side on length direction is compared, more by supplying space side on the length direction of collector.But this feelings Under condition, since the 1st guide part is with towards the side opposite with flat tube side and positioned at supply on the length direction of collector The mode of space side stretches, therefore, can make refrigerant piping with import in the end of side that space is connect in collector Length direction on be located at by supplying the end of space side and more leaned on and the opposite side in supply space side than the 1st guide part.

The heat exchanger of 6th viewpoint is in the heat exchanger of the 5th viewpoint, and the 1st division and the 1st guide part are as a portion Part and will be divided into collector import space and supply space.

In the heat exchanger, the 1st division and the 1st guide part is made to be configured to a component, is led being divided into collector Enter space and supply space, thus, it is possible to cut down number of components.

The heat exchanger of 7th viewpoint also has in the heat exchanger of any one viewpoint in the 1st viewpoint~the 6th viewpoint There are flat tube sidewall portion and the 2nd guide part.Flat tube sidewall portion is formed in the length side of collector in the flat tube side for importing space Upwards with supply space side opposite side wall.2nd guide part is set to one opposite with flat tube side of flat tube sidewall portion Side, with towards the side opposite with flat tube side and continuously or the stage be located at supply space side opposite side side Formula stretching, extension.

In addition, flat tube sidewall portion is also configured to the plate in the planar extension orthogonal with the length direction of collector Shape.

In the heat exchanger, even if including the length in collector in the coupling part in refrigerant piping and importing space It is located at the position that the side opposite with supply space side is more leaned on than flat tube sidewall portion on direction, since the 2nd guide part is by the 2nd The part of supply space side in guide part will imported into the refrigerant imported in space via refrigerant piping and guide to supply Space side, thereby, it is possible to be sent to the position of the supply space side of flat tube sidewall portion.Therefore, even if in refrigerant piping and leading The coupling part for entering space includes to be located at more to lean on than flat tube sidewall portion and supply space side phase on the length direction of collector The position of anti-side also can convey refrigerant to the position of the supply space side of flat tube sidewall portion, also, by making to lead Enter the end of the side opposite with supply space side on the length direction of collector of the space segment of the flat tube side in space Position be in supply space side, be able to suppress flat tube and import space connection.

In addition, the 2nd guide part with the direction side opposite with flat tube side on the length direction of collector to be located at With supply space side opposite side mode stretch, therefore, can make and import space connection refrigerant piping in collector Length direction on supply space side opposite side end be located at than the 2nd guide part more by supply space side position.

In addition, in the heat exchanger, be also possible to import in space on the length direction of collector with supply space The end of the opposite side in side is made of flat tube sidewall portion and the 2nd guide part, import space in supply space side by with The orthogonal planar extension of the length direction of collector and the flat part composition for being formed with spray nozzle part.In the feelings for using flat part in this way Under condition, used refrigerant piping with import interval of the end for the side that space is connect on the length direction of collector In wider situation, refrigerant piping with import the end of side that space is connect on the length direction of collector with supply The end of space side opposite side is easy to be located at more by the side opposite with supply space side.But in this case, due to 2 guide parts stretch in a manner of with being located at towards the side opposite with flat tube side with supply space side opposite side, because This, can make empty with supply on the length direction of collector in the end for the side of refrigerant piping connecting with importing space Between side opposite side end be located at than the 2nd guide part more by supply space side position.

The heat exchanger of 8th viewpoint is in the heat exchanger of the 7th viewpoint, and flat tube sidewall portion and the 2nd guide part are as one A component and constitute import space bottom.

In the heat exchanger, flat tube sidewall portion and the 2nd guide part is made to be configured to a component, constitutes and import space The part of the side opposite with supply space side, thus, it is possible to cut down number of components.

The heat exchanger of 9th viewpoint also has in the heat exchanger of any one viewpoint in the 1st viewpoint~the 4th viewpoint There are the 1st division, the 1st guide part, flat tube sidewall portion and the 2nd lower section guide part.Spray nozzle part is formed in the 1st division.1st Division will be divided into collector in flat tube side and import space and supply space.1st guide part be set to the 1st division with The opposite side in flat tube side, with towards the side opposite with flat tube side and continuously or the stage be located at supply space The mode of side stretches.Flat tube sidewall portion import space flat tube side be formed in collector length direction on supply space The wall of side opposite side.2nd guide part is set to the side opposite with flat tube side of flat tube sidewall portion, with towards with The opposite side in flat tube side and continuously or the stage be located at supply space side opposite side mode stretch.Refrigerant is matched It manages and is connect with the part by the 1st guide part and the encirclement of the 2nd guide part.

Moreover, being set to the nozzle for the part inclination divided parts 70 with nozzle that the 1st upper layer is turned back in connected space 90A Forming portion 71 and demarcation plate 91 are respectively positioned between neighbouring flat perforated pipe 63.

(5) the 1st upper layers are turned back the flowing of the refrigerant in connected space 90A

In the following, the 1st upper layer in the case where to the evaporator for being used as refrigerant in middle outdoor heat exchanger 11 constructed above The flowing of the refrigerant in connected space 90A of turning back is illustrated.

It flows into via the 1st connecting pipings 24 than the importing space 97 of part inclination divided parts 70 more on the lower with nozzle Refrigerant a part be moved to the lower section of rising space 98A after, via the part inclination divided parts 70 with nozzle The nozzle 71a of nozzle forming portion 71 is blown afloat into rising space 98A.Here, flat porous is not connected in importing space 97 Pipe 63, therefore, refrigerant will not directly be flowed to flat perforated pipe 63 from space 97 is imported.

The refrigerant that is admitted in the 98A of rising space rises in the 98A of rising space on one side, be diverted on one side according to The flat perforated pipe 63 of each height and position connection.In addition, reaching the situation near upper end of the rising with space 98A in refrigerant Under, it is sent to decline space 98B via the upper communication port 95a of circulation dividing plate 95, is declined in the 98B of decline space.

The refrigerant declined in the 98B of decline space decline space 98B lower end, along the portion with nozzle Decline while the upper surface of the rake 72 of point inclination divided parts 70 is towards 63 side of flat perforated pipe.Then, it is used in decline The refrigerant declined in the 98B of space is directed to rising space via the lower communication port 95b of circulation dividing plate 95 again 98A.In this way, refrigerant is recycled in circulation space 98.

In addition, the 2nd upper layer is turned back, construction in connected space 90B and refrigerant flowing are turned back with above-mentioned 1st upper layer and are connected to Construction and refrigerant mobile phase in the 90A of space is same, and and the description is omitted.

In addition, turn back construction in connected space 90C and refrigerant flowing about the 3rd upper layer, above-mentioned 1st upper layer is turned back company The part inclination divided parts 70 with nozzle in logical space 90A, which corresponds to, to be constituted the 3rd upper layer and turns back the lower end of connected space 90C The dividing plate 99 with nozzle this point it is different, still, other constructions and refrigerant mobile phase are same, and and the description is omitted.

(6) feature

(6-1)

The outdoor heat exchanger 11 of present embodiment, which passes through, is set to the nozzle that the part with nozzle tilts divided parts 70 The nozzle 71a of forming portion 71 blows afloat refrigerant, and thereby, it is possible to make refrigerant in the rising space 98A in circulation space 98 Rise.It, also can be to the in the case where using outdoor heat exchanger 11 under the less situation of the internal circulating load of refrigerant as a result, 1st upper layer of 2 total collection pipes 90 turn back connected space 90A top connection flat perforated pipe 63 fully supply refrigerant (the 2nd upper layer turn back connected space 90B also the same).

In addition, can make when the internal circulating load of the refrigerant in outdoor heat exchanger 11 is more due in rising space Rise surgingly in 98A and concentrates on rising with the refrigerant of the top of space 98A via upper communication port 95a, decline space 98B and lower communication port 95b are recycled, and rising space 98A is again returned to.

As described above, refrigerant can also be directed to respectively and is connected to respectively in the case where the variation of the internal circulating load of refrigerant The bias current of refrigerant between multiple flat perforated pipes 63 can be suppressed to by evenly distributedization of the flat perforated pipe 63 of height It is smaller.

(6-2)

In the present embodiment, it turns back connection using via the 1st connecting pipings 24 to the 1st upper layer of the 2nd total collection pipe 90 Space 90A supplies the construction of refrigerant, still, for (functioning as condenser for the refrigerant flowing before shunting In the case of for for the refrigerant flowing behind interflow) outer diameter of the 1st connecting pipings 24 is easy to increase.

Therefore, in the above-described embodiment, the outer diameter of the 1st connecting pipings 24 is than the part with nozzle in importing space 97 The interval for tilting the nozzle forming portion 71 in divided parts 70 and the up and down direction between demarcation plate 91 is big, than flat perforated pipe 63 Up and down direction interval it is big.In addition, the upper end of the 1st connecting pipings 24 is located at the flat perforated pipe of the surface than nozzle 71a 63 lower end place closer to the top.

In this case, as shown in figure 18, it is assumed that constituting the demarcation plate 91 for importing the upper and lower surfaces in space 97 In the case where being made of with the dividing plate 971 with nozzle the component of horizontal extension, 63 side of flat perforated pipe in space 97 is imported Up and down direction width it is also easy to increase.Therefore, the feelings of flat perforated pipe 63 are configured at a prescribed interval in the up-down direction Under condition, becomes and be connected with the structure of flat perforated pipe 63 in the importing space 97.In this case, with the dividing plate with nozzle The flat perforated pipe 63 that the circulation space 98 of 971 top connects is compared, and more refrigerants intensively flow into and with nozzle Dividing plate 971 lower section the flat perforated pipe 63 (in Figure 18 dotted line surround flat perforated pipe 63) for importing space 97 and connecting (this is because generating the pressure loss in the nozzle 71a of the dividing plate 971 with nozzle, therefore, the pressure of refrigerant is in nozzle The upstream side of 71a and downstream side difference.).Therefore, the bias current of refrigerant is generated between multiple flat perforated pipes 63.It produces in this way When raw bias current, the state difference of the refrigerant flowed respectively in multiple flat perforated pipes 63 is (about a part, for evaporating completely Refrigerant flowing position it is longer, about another part, the refrigerant of non-evaporating completely outflow etc., as a result) possibly can not fill The performance of outdoor heat exchanger 11 is waved in distribution.On the other hand, when become it is this import space 97 be not connected with flat perforated pipe 63 Structure when (omit Figure 18 in dotted line surround flat perforated pipe 63 when), can not with biggish 1st connecting pipings 24 of outer diameter Width corresponding amount flat perforated pipe 63 is set, the radical of flat perforated pipe 63 is reduced, the ability drop of outdoor heat exchanger 11 It is low.Moreover, making flat perforated pipe 63 by additional flat perforated pipe 63 omitted in this way in the top in circulation space 98 Radical become identical quantity in the case where, outdoor heat exchanger 11 is enlarged in the up-down direction.

In contrast, it in the outdoor heat exchanger of present embodiment 11, is using via the 1st connecting pipings 24 to the 2nd 1st upper layer of total collection pipe 90 turn back connected space 90A supply refrigerant construction in the case where, even if in the 1st connecting pipings In the case that 24 outer diameter is bigger than the interval of the up and down direction of flat perforated pipe 63, the outer diameter of the 1st connecting pipings 24 it is more empty than importing Between the nozzle forming portion 71 in the part inclination divided parts 70 with nozzle in 97 and the up and down direction between demarcation plate 91 In the case that interval is big, the upper end of the 1st connecting pipings 24 be located at the surface than nozzle 71a flat perforated pipe 63 lower end more In the case where place against the top, divided parts 70 is tilted by using the part with nozzle with rake 72, connect and matches with the 1st The space of the connecting side of pipe 24 can make the width of the up and down direction in the space of the lower section of the nozzle 71a imported in space 97 more It is narrow.

Thereby, it is possible to the width that constriction imports the up and down direction of 63 side of flat perforated pipe in space 97, will be with importing space The radical of the flat perforated pipe 63 of 97 connections is suppressed to less.

Particularly, in the present embodiment, it is configured to the circulation space only turned back in connected space 90A on the 1st upper layer 98 sides connect flat perforated pipe 63, are not connected with flat perforated pipe 63 importing space 97.Therefore, it can be adequately suppressed multiple flat The bias current of refrigerant between flat antipriming pipe 63.

Moreover, not needing to omit flat perforated pipe 63, or in circulation space in the case where inhibiting this bias current yet Flat perforated pipe 63 is added in 98 sides, it is thus possible to enough avoid the reduction of performance and the enlargement of outdoor heat exchanger 11.
