HEAT PUMP DEVICE FOR VEHICLE

摘要

A heat pump device for a vehicle, capable of effectively utilizing the heat of structural members. This heat pump device for a vehicle comprises: an electric compressor for compressing and discharging refrigerant; and a high-temperature water-refrigerant heat exchanger for conducting heat exchange between the high-temperature, high-pressure refrigerant discharged by the electric compressor and a first cooling liquid which is antifreeze; the high-temperature water-refrigerant heat exchanger surrounding and being in contact with the electric compressor so as to be capable of heat exchange with the electric compressor.

主权项

1. An in-vehicle heat pump apparatus comprising:
an electric compressor that compresses and discharges refrigerant; a high-temperature-side water refrigerant heat exchanger that performs heat exchange between a high-temperature and high-pressure refrigerant discharged from the electric compressor and a first coolant that is an anti-freeze liquid, wherein the high-temperature-side water refrigerant heat exchanger surrounds the electric compressor and is in contact with the electric compressor in a heat exchangeable manner.
