Technical field

The present invention relates to heat-exchangerss of the plate type.

Background technique

The known heat-exchangers of the plate type that heat exchange is carried out using medium.For example, as it is known that following heat-exchangers of the plate type: will be more A laminating metal plate for being carried out similarly punch process makes medium between the first metal plate and the second metal plate of stacking Stacking space and stacking the second metal plate and third metal plate between stacking space in flowing come carry out heat exchange (for example, Patent Documents 1 to 4).

Heat-exchangers of the plate type be configured between the medium and a pair of of metal plate across the medium for flowing through stacking space into Row heat exchange.Specifically, first layer metal plate and second layer metal plate with first layer metal plate and second layer metal plate it Between first cascade space in the medium that flows carry out heat exchange, second layer metal plate and third layer metal plate in second layer gold Belong to the medium flowed in the second stacking space between plate and third layer metal plate and carries out heat exchange, third layer metal plate and the 4th Layer metal plate and the third between third layer metal plate and the 4th layer of metal plate are laminated the medium flowed in space and carry out hot friendship It changes.

In heat-exchangers of the plate type as described above, it is formed in the flow path in first cascade space and is formed in the second stacking sky Between flow path become with same distance flow path.Therefore, substantially uniform heat exchange can be carried out between multiple metal plates.

Summary of the invention

Subject to be solved by the invention

However, in the diversified situation in view of heat exchange mechanism, it is also contemplated that using different multiple of thermal capacity The situation of medium progress heat exchange.In addition, it is also contemplated that using the different a variety of media of thermal coefficient situation.Above-mentioned such Previous heat-exchangers of the plate type in the case where, even if the thermal capacity of the medium of a side is low, the heat exchanger effectiveness of heat exchanger It is likely to depend upon the medium of another party with large heat capacity and is suppressed.In addition, even if the thermal coefficient of the medium of a side is high, heat The heat exchanger effectiveness of exchanger is also possible to depend on the medium of the low another party of thermal coefficient and be suppressed.

The present invention is completed to solve the problems, such as described above, and its purpose is to provide a kind of board-like heat exchanges Device, even if in the case that thermal capacity is different between the multiple media for carrying out heat exchange, even if by different more of thermal coefficient In the case that a medium is used for heat exchange, the inhibition of the heat exchanger effectiveness of the medium depending on a side can be also reduced.

Means for solving the problems

The heat-exchangers of the plate type of one aspect of the present invention carries out heat exchange using multiple heat transfer plates of stacking.Multiple heat transfers Plate has the first heat transfer plate and the second heat transfer plate, and first heat transfer plate carries out heat exchange, and second heat transfer plate is with first First cascade space flow for first medium is set between heat transfer plate and is laminated, progress heat exchange.First heat transfer plate and second Heat transfer plate has respectively: the plate main body of rectangular shape, carries out heat exchange；For making the first medium of first medium inflow and outflow It is situated between with inflow part and first medium outflow portion or second medium inflow part and second for making second medium inflow and outflow Matter outflow portion；And protrusion, connect with the one end of the longitudinal direction of plate main body and be isolated with another side, to stacking side To prominent, the flow path of formation first medium or second medium.In first medium inflow part and first medium outflow portion extremely A corner of few side configuration in two corners of one end for being located at the plate main body that protrusion connects.Second medium inflow part And at least one party's configuration in second medium outflow portion is in two corners of the another side for the plate main body for being located at protrusion isolation In a corner.It is laminated in such a way that the one end of the first heat transfer plate connects with the another side of the second heat transfer plate.

The effect of invention

According to an aspect of the present invention, though between the multiple media for carrying out heat exchange the different situation of thermal capacity Under, even if can also reduce Jie depending on a side in the case where the different multiple media of thermal coefficient are used for heat exchange The inhibition of the heat exchanger effectiveness of matter.
