Abstract

The present invention provides a configuration of a vehicle heat exchanger. The configuration of the vehicle heat exchanger comprises an outdoor heat exchanger of a heat pump system of a vehicle air conditioning device and a low water temperature radiator used for cooling the low temperature heating elements, including a vehicle driving motor, and is characterized in that relative to the outdoor heat exchanger, the low water temperature radiator is arranged at the upstream side of a cooling airflow direction.

Description

technical field [0001] The present invention relates to a condenser (hereinafter referred to as an outdoor heat exchanger) for a heat pump system of an air conditioner in a hybrid electric vehicle (HEV), an electric vehicle (EV), a plug-in hybrid electric vehicle (PHEV), etc. , an arrangement structure of a vehicle heat exchanger in which a low-temperature radiator for cooling electronic equipment such as an inverter is arranged on the upstream side of the cooling air flow direction. Background technique [0002] As shown in Japanese Patent Application Laid-Open No. 2011-98628, a hybrid vehicle (HEV, PHEV) is provided with two drive sources, an engine and a running motor, and is equipped with a device for converting DC power from an onboard secondary battery into AC power. It is also an inverter that supplies the driving motor. In such a hybrid vehicle, in addition to the cooling of the engine, the running motor and the inverter of the hybrid system also need to be cooled. ...
