The flowing of the cold-producing medium in heat exchanger 1B is for upstream side heat exchange department 1Ba, identical with embodiment 2.And And, the cold-producing medium flowed out from the refrigerant outlet pipe arrangement 20a of upstream side heat exchange department 1Ba from refrigerant inlet pipe arrangement 100a through across Row pipe arrangement 90 flows into the chamber F of downstream heat exchange department 1Bb.It is flowed into the cold-producing medium of chamber F from the flat tube connected with chamber F Flowing towards the other end in one end of group, flows into chamber H.And, the cold-producing medium being flowed into chamber H is here turned back, from chamber H Flow towards the other end in the one end of other the flat tube group connected.And, each cold-producing medium flowed out from this other end is at chamber G Interflow, flows out to outside from refrigerant outlet pipe arrangement 200a.
In the flowing of superincumbent cold-producing medium, owing to arranging opposite to each other with the end of the refrigerant inlet side of each flat tube group There is groove 14, so, as above-mentioned embodiment 1,2, the surface tension effects by liquid refrigerant suppresses the inclined of cold-producing medium Stream, from each chamber to each path assignment system cryogen substantially uniformly.
Then, the reason changing number of paths at upstream side heat exchange department 1Ba and downstream heat exchange department 1Bb is carried out Explanation.
In the case of heat exchanger 1B is used as vaporizer, owing to cold-producing medium flows into gas-liquid two-phase state, Become gas refrigerant eventually and flow out, so, aridity becomes big along with the latter half of of whereabouts stream.In the situation that aridity is little Under, due to little by crushing during stream, it is preferred, therefore, that make refrigerant flow rates accelerate, promote the coefficient of overall heat transmission.On the other hand, dry In the case of dry degree is big, due to big by crushing during stream, it is preferred, therefore, that make refrigerant flow rates slow, more increase number of path Amount refrigerant flow rates is the slowest.
In heat exchanger 1B, in the upstream side heat exchange department 1Ba being equivalent to stream first half, due to doing of cold-producing medium Dry degree is little, so, make number of paths tail off, promote refrigerant flow rates, promote the coefficient of overall heat transmission.On the other hand, stream is being equivalent to In latter half of downstream heat exchange department 1Bb, owing to aridity becomes big, so, make number of paths many, make under refrigerant flow rates Fall, seeks to reduce the pressure loss.
As explained above, according to present embodiment 3, it is possible to obtain and the identical effect of embodiment 1,2, and Owing to making many array structures, thus it is possible to improve heat-exchange capacity.It addition, because reduce little by the aridity of cold-producing medium The air number of paths by direction upstream side, promotes refrigerant flow rates, promotes the coefficient of overall heat transmission, so, it also is able to scheme in this respect Seek raising heat-exchange capacity.
It addition, in present embodiment 3, illustrate 2 array structures, but it is also possible to make the structure that 3 row are above.
It addition, in the respective embodiments described above, illustrate the example that outer shape is square shape of collector, but, not It is limited to square shape, it is also possible to make cylindrical shape.It addition, in the case of multiple row as embodiment 3, from guaranteeing as collection Size needed for pipe and seek from the viewpoint of row interfere with each other, to be preferably made to square shape.
