Temperature control apparatus for vehicle
First Claim
1. A temperature control apparatus for a vehicle, comprising:
- an electric device that is cooled by a cooling fluid;
a heater core that is disposed adjacent to the interior heat exchanger of a heat pump to receive the cooling fluid that has cooled the electric device;
a first valve that controls supply of the cooling fluid from the electric device to the heater core;
a heat pump warmer that allows the cooling fluid from the electric device to circulate and exchange heat, is disposed in a coolant pipe for supplying a coolant to the exterior heat exchanger of the heat pump;
a second valve that controls supply of the cooling fluid from the electric device to the heat pump warmer; and
a cooling fluid pump that pumps the cooling fluid from the electric device to be supplied to the heater core and the heat pump warmer,wherein a common supply line for discharging the cooling fluid and a common collecting line for collecting the cooling fluid are connected to the electric device,the common supply line is divided into a first supply line connected to the heater core and a second supply line connected to the heat pump warmer,the common collecting line is divided into a first collecting line connected to the heater core and a second collecting line connected to the heat pump warmer,the cooling fluid pump is disposed in the common supply line,the first valve is disposed in the first supply line, andthe second valve is disposed in the second supply line.

Abstract
A temperature control apparatus for a vehicle is provided that includes an electric device that is cooled by circulating cooling fluid. A heater core is disposed adjacent to an interior heat exchanger of a heat pump to receive the cooling fluid that has cooled the electric device. In addition, the apparatus includes a first valve that controls the supply of the cooling fluid from the electric device to the heater core. Accordingly, using the temperature control apparatus, air-conditioning performance of vehicles, is improved using heat generated from electric devices, together with a heat pump, when the vehicles, such as hybrid or electric vehicles, are equipped with electric devices, such as a motor, an inverter, and a converter and the electric devices are air-conditioned using the heat pump.
