<P>PROBLEM TO BE SOLVED: To provide a heat exchanger capable of suppressing an increase in passage resistance and the occurrence of refrigerant flow noise when a refrigerant flows in through a refrigerant inlet. <P>SOLUTION: An evaporator 1 includes: a heat exchange core 4 having a plurality of heat exchange tubes 19; and headers 5, 14 disposed in both sides in a longitudinal direction of the heat exchange tubes 19 in the heat exchange core 4, the headers having refrigerant inlets 8, 17 at one end, respectively. The headers 5, 14 comprise: header bodies 24, 25 having both ends opened; caps 26, 27, 28, 29 closing both of the open ends of the header bodies 24, 25; and partitioning members 35, 36 that partition the inside of the header bodies 24, 25 into first spaces 31, 32 communicating with the heat exchange tubes 19 and second spaces 33, 34. The refrigerant inlets 8, 17 are formed on the caps 26, 28 at one end to communicate with the second spaces 33, 34. Openings of the refrigerant inlets 8, 17 are formed to have larger areas than passage cross-sectional areas in the middle in the longitudinal direction of the second spaces 33, 34. <P>COPYRIGHT: (C)2013,JPO&INPIT |
