Specific embodiment

Below with reference to embodiment, the present invention will be further described, but is not limited to the content on specification.

As shown in Figure 1, the invention discloses a kind of oil eliminators, comprising: shell 10 and heat exchanger 40, the interior setting of shell 10 There is shoe cream room 30；Heat exchanger 40 is arranged in shoe cream room 30, and heat exchanger 40 is used to exchange heat with the lubricating oil filtered out.Of the invention Oil eliminator, by heat exchanger being arranged in the shoe cream room 30 of shell 10, the lubricating oil that oil eliminator can be filtered out is straight It connects in the cooling of oil eliminator internal heat, it is empty since oil eliminator separates lubricating oil and refrigerant, and in shoe cream room 30 Between it is larger, cold media gas can quickly be discharged, and will not influence the heat transfer effect of lubricating oil, mention the cooling effect of lubricating oil significantly It is high.

In the above-described embodiments, the bottom of shoe cream room 30 is arranged in heat exchanger 40.Oil eliminator of the invention will be by that will change The bottom of shoe cream room 30 is arranged in hot device 40, thus can be so that heat exchanger all submerges after lubrication buildup to certain altitude In lubricating oil, heat exchange is carried out to the maximum extent to improve, greatly improves the cooling effect of lubricating oil.

In the above-described embodiments, heat exchanger 40 includes the heat exchanger tube of internal circulation refrigerant, and heat exchange pipe dish is located at shoe cream room In 30.Oil eliminator of the invention is located in shoe cream room 30 by the pipe dish that will exchange heat and forms heat exchanger, and heat exchanger tube internal circulation is cold Matchmaker, refrigerant absorb lubricating oil heat after evaporation to further absorb lubricating oil heat, thus cutting oil.And energy Enough using the space in oil eliminator, heat exchanger and oil eliminator are integrated in one, the installation space of equipment can be saved.

In the above-described embodiments, heat exchanger 40 is oil cooler.Oil eliminator of the invention, by the way that oil cooler to be arranged In the shoe cream room 30 of shell 10, the lubricating oil that oil eliminator filters out can directly be cooled down in oil eliminator internal heat, Since oil eliminator separates lubricating oil and refrigerant, and space is larger in shoe cream room 30, and cold media gas can be arranged quickly Out, the heat transfer effect that will not influence lubricating oil greatly improves the cooling effect of lubricating oil.

In the above-described embodiments, exhaust entrance 11 and air exit 12, exhaust entrance 11, exhaust are additionally provided on shell 10 Outlet 12 is connected to shoe cream room 30 respectively.Oil eliminator of the invention makes to press by setting exhaust entrance 11 and air exit 12 The exhaust of contracting machine enters in shoe cream room 30 from exhaust entrance 11, and after oil eliminator filters out lubricating oil, compressor air-discharging is from being vented out Mouth 12 is discharged, and compressor air-discharging will not accumulate in shoe cream room 30, it can thus be avoided influencing the heat transfer effect of lubricating oil, mentions The cooling effect of high lubricating oil.

In the above-described embodiments, oil eliminator further include: filter device 20, filter device 20 are located in shoe cream room 30, mistake Filter device 20 is used to filter out the lubricating oil in compressor air-discharging, and the lubricating oil that filter device 20 filters out is stored in shoe cream room 30 It is interior.Lubricating oil in compressor air-discharging can be filtered out by the way that filter device 20 is arranged, be filtered out by oil eliminator of the invention Lubricating oil is dropped onto directly to exchange heat with heat exchanger 40 in shoe cream room 30 and be cooled down, and greatly improves the heat transfer effect of lubricating oil.

In the above-described embodiments, filter device 20 includes strainer, and strainer is arranged at 12 position of air exit, and strainer is used for Filter out the lubricating oil in compressor air-discharging.Oil eliminator of the invention can by being arranged strainer at 12 position of air exit Preferably to filter out the lubricating oil in compressor air-discharging, oil effect is improved.

In the above-described embodiments, 10 bottom of shell is additionally provided with lubricating oil outlet 13, lubricating oil outlet 13 and shoe cream room 30 Bottom connection.Oil eliminator of the invention, by the way that lubricating oil outlet 13 to be connected to 30 bottom of shoe cream room, it is ensured that discharge Lubricating oil is the lower lubricating oil of 30 bottom temp of shoe cream room.

According to another aspect of the present invention, a kind of water cooler is disclosed, including above-mentioned oil eliminator.

In the above-described embodiments, water cooler further include: condenser 50, condenser 50 are communicated with the oil separator.Heat exchanger 40 be oil cooler, and the outlet 42 of oil cooler is connected to the refrigerant inlet 51 of condenser 50, the entrance 41 of oil cooler with it is cold The refrigerant exit 52 of condenser 50 is connected to by refrigerant pipeline 60.It is provided with exhaust entrance 11 and air exit 12 on shell 10, arranges Gas entrance 11, air exit 12 are connected to shoe cream room 30 respectively, and exhaust entrance 11 is also communicated with compressor, air exit 12 also with The refrigerant inlet 51 of condenser 50 is connected to.

As shown in Fig. 2, water cooler of the invention, carries out oil to compressor air-discharging by oil eliminator, gas separates, high temperature Cold media gas is discharged into condenser 50, and high temperature grease then accumulates in oil eliminator bottom.After taking condensation from 50 bottom of condenser Refrigerant liquid become and be sent into oil cooler after low temperature refrigerant gas-liquid mixture after reducing pressure by regulating flow, can be to oil cooler Peripheral lubrication oil cools down, and the cold media gas of the evaporation after absorbing lubricating oil heat is then fed again into condenser, shape It is recycled at one, to realize persistently cooling to lubricating oil.To make the temperature into compressor drum chamber lubricating oil It reduces, realizes better compressor cooling effect, the range of operation of compressor can be promoted, application range is wider；

In the above-described embodiments, water cooler further include: electric expansion valve 70, temperature sensor 80 and control device, electricity Sub- expansion valve 70 is arranged on refrigerant pipeline 60；Temperature sensor 80 is arranged at 11 position of exhaust entrance, temperature sensor 80 For detecting the temperature of compressor air-discharging；Control device is separately connected electric expansion valve 70 and temperature sensor 80, control device For the temperature according to compressor air-discharging, the aperture of electric expansion valve 70 is controlled, to adjust the temperature of oil cooler.

Water cooler of the invention can detecte delivery temperature by temperature sensor, by actually detected value size with Setting value size can dynamically adjust electronic expansion valve opening.If delivery temperature is higher than setting value, big electric expansion valve is opened Aperture increases into the low temperature refrigerant flow in built-in oil cooler, and oil eliminator bottom lubricating oil temperature is enabled to drop Lower, subzero oil can more preferably cool down compressor drum chamber, and delivery temperature then can be reduced accordingly；On the contrary, if exhaust Temperature is lower than setting value, then turns down electronic expansion valve opening, can into the low temperature refrigerant flow-reduction in built-in oil cooler Weaken oil eliminator bottom lubricating oil temperature and drop to obtain amplitude, the cooling compressor drum chamber effect of medium temperature lubricating oil is not so good as low-temperature lubrication Oil, delivery temperature then can accordingly rise.

Obviously, above embodiment of the invention be only to clearly illustrate example of the present invention, and not be Restriction to embodiments of the present invention.For those of ordinary skill in the art, on the basis of the above description also It can make other variations or changes in different ways.Here all embodiments can not be exhaustive.It is all to belong to this The obvious changes or variations that the technical solution of invention is extended out are still in the scope of protection of the present invention.
