ABSTRACT:
In a condenser of a refrigerant cycle, a throttle portion is provided at a predetermined position in one of first and second header tanks to decompress refrigerant while refrigerant meanderingly flows within the one of the first and second header tanks. Therefore, refrigerant from the throttle portion is sufficiently mixed with refrigerant directly flowing from tubes into a downstream space of the throttle portion in the one of the first and second header tanks. Accordingly, even when gas refrigerant is directly introduced from a part of the tubes directly into the lower downstream space, the gas refrigerant can be effectively heat-exchanged with the refrigerant flowing from the throttle portion. As a result, it can restrict refrigerant from being discharged from the condenser in a gas-liquid two-phase state.
