Abstract
The purpose of the present invention is to integrate a heating air-conditioning configuration and a cooling system of a vehicle, to enable more efficient heating air conditioning. A vehicle air-conditioning device is provided with: a radiator used for cooling a vehicle-side heat-generating apparatus; a heater core that exchanges heat between a coolant and air to be blown into a vehicle cabin; and coolant passages through which the coolant flows so as to be circulated between the heater core and the radiator. Furthermore, the vehicle air-conditioning device is provided with a water heater which is integrated with a power element for air conditioning formed of a semiconductor element with high heat resistance and which causes the power element and a heat-generating body to heat the coolant flowing to the heater core.
