Formed by three, but it can also apply to the heat exchanger of heat exchange module more than 2 overlapping four.
In addition it is also possible in addition to communication member 28 or interconnecting part 50 are arranged at into lower condensate sump connector 6L, also set
It is placed in upper condensate sump connector 4U.By the way that communication member 28 or interconnecting part 50 are formed in whole upper condensate sump connector 4U, respectively
Underside gap 30 necessarily can all be used as downside in the way of the whole region throughout lower condensate sump connector 6L length direction Y
Draining road 40 is used.
Thus, lower condensate sump connector 6L drainage can be further improved, and then the durability of heat exchanger 1 can be realized
And the further raising of the thermal efficiency.But, learnt by experiment, communication member 28 is being arranged at lower condensate sump connector 6L's
In the case of, compared with communication member 28 to be arranged to upper condensate sump connector 4U situation, the thermal efficiency of heat exchanger 1 can become
Height, therefore, the structure that communication member 28 is arranged at into lower condensate sump connector 6L are conducive to the thermal efficiency of heat exchanger 1 to improve.
In addition, in the heat exchanger 1 of above-mentioned embodiment and variation, being formed with upper condensate sump connector 4U
Side clearance 16, so that it is guaranteed that there is upside draining road 26.But, even if not forming side clearance 16 and upside draining road 26, as long as
It is, at least in lower condensate sump connector 6L formation underside gaps 60, and to ensure to have the heat exchanger on downside draining road 40.
In this case, can at least improve on each core 12 condense and flow down, and drip to lower condensate sump connector 6L upper surface and
The drainage of the condensed water of attachment, and then the durability of heat exchanger 1 and the raising of the thermal efficiency can be realized.
In addition, the refrigerant used in the heat exchanger 1 of above-mentioned embodiment and variation is carbon dioxide, but also may be used
To use other refrigerants.But, as in the present embodiment, using each header tank 4 being made up of the smaller pipe of diameter,
The heat exchanger 1 of the structure of 6, and overlapping more than three heat exchange module 2 is excellent in pressure-resistant aspect of performance, therefore, more manages
Think, use carbon dioxide coolant.
