EVAPORATOR, MANUFACTURING METHOD OF THE SAME, HEADER FOR EVAPORATOR AND REFRIGERATION SYSTEM

摘要

The evaporator includes the upper side and lower header members 10 and 50 disposed at the upper and lower end of the core 1. One end of each tube 6 constituting the upstream-side tube group P 1 is connected to the inlet-side tank 11, while the other end to the lower header member 50. One end of each tube 7 constituting the downstream-side tube group P 2 is connected to the outlet-side tank 12, while the other end to the lower header member 50. The refrigerant flowed into the inlet-side tank 11 is introduced into the outlet-side tank 12 by passing through the upstream-side tube group P 1 , the lower header member 50 and the downstream-side tube group P 2 , so that the refrigerant evaporates by exchanging heat with ambient air A. Accordingly, it improves the heat exchange performance and decreases the thickness.
