Title:
VEHICULAR AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/270594
Kind Code:
A1
Abstract:
To enable efficient heat usage by using waste heat of in-vehicle equipment, and in particular in-vehicle equipment of a driving system including a battery, a motor, an inverter, and so forth.　The present invention provides a vehicular air conditioning device that includes a cabin air conditioning unit having a heat-absorbing heat exchanger 30, and a heat-dissipating heat exchanger 40 that is provided on a downstream side of the heat-absorbing heat exchanger on a blowing flow passage. The heat-dissipating heat exchanger is a heat exchanger that performs heat dissipation of a heat medium that has recovered waste heat from the in-vehicle equipment. The cabin air conditioning unit includes a heat-dissipating blowing flow passage 50 that discharges wind that has passed through the heat-dissipating heat exchanger to outside of the vehicle.
