To improve a COP in a vehicular temperature regulation system comprising a plurality of systems of refrigeration cycles.SOLUTION: A heat exchanger is used as a high-pressure side heat exchanger of a vehicular temperature regulation system comprising a first refrigerant circuit and a second refrigerant circuit each comprising a compressor, the high-pressure side heat exchanger, a pressure reducing part, and a low-pressure side heat exchanger, and includes a first refrigerant flow passage comprised in the high-pressure side heat exchanger of the first refrigerant circuit, a second refrigerant flow passage comprised in the high-pressure side heat exchanger of the second refrigerant circuit, and a heat medium flow passage common to the high-pressure side heat exchanger of the first refrigerant circuit and the high-pressure side heat exchanger of the second refrigerant circuit. The heat medium flow passage is constituted so as to be capable of being connected to an outside air heat exchanger for exchanging heat between a heat medium and outside air.SELECTED DRAWING: Figure 1
