  The evaporator with a cold storage function (1) described above includes a compressor that uses a vehicle engine as a drive source, a condenser that cools the refrigerant discharged from the compressor (refrigerant cooler), and an expansion valve that depressurizes the refrigerant that has passed through the condenser ( A refrigeration cycle is configured together with a decompressor, and is mounted as a car air conditioner on a vehicle, such as an automobile, that temporarily stops an engine that is a drive source of a compressor when the vehicle is stopped.

  During normal cooling when the compressor is operating, the low-pressure gas-liquid mixed-phase two-phase refrigerant compressed by the compressor and passed through the condenser and the expansion valve passes through the refrigerant inlet (7) and has an evaporator (1 ) Into the front upper header portion (5), through the entire refrigerant flow pipe (12) and both lower header portions (9) and (11) into the rear upper header portion (6) and into the refrigerant outlet (8).
