Thermal management system of hybrid power vehicle type and vehicle

Abstract

The thermal management system comprises a power battery loop, an engine hot water loop and an air conditioner refrigeration loop, the engine hot water loop comprises an engine, a three-way proportional valve and a warm air core body which are connected in series, and a second outlet of the three-way proportional valve communicates with the water inlet end of a hot water channel of a battery cooler; the water outlet end of the warm air core body and the water outlet end of the hot water channel of the battery cooler are communicated with the first water inlet end of the engine; the air conditioner refrigerating loop is communicated with a cooling water channel of the battery cooler, the power battery loop is communicated with a heat exchange channel of the battery cooler, and the power battery loop exchanges heat with the engine hot water loop and the air conditioner power battery loop through the battery cooler. The heat of the engine and the power battery can be effectively combined, the PTC operation time is shortened to the maximum extent in a low-temperature environment, the duration that the power battery reaches the optimal working environment temperature is shortened, and the electric quantity loss caused by the requirement of the power battery is reduced.

Description

technical field [0001] The invention relates to the field of heat management of a complete vehicle, in particular to a heat management system and a vehicle of a hybrid vehicle. Background technique [0002] Due to the promotion of national strategies, hybrid vehicles have developed rapidly in recent years, and major traditional car companies and joint ventures have joined the ranks of competition. Hybrid vehicles have added heat-generating components such as synthesis boxes, motor controllers, and power batteries on the basis of original fuel vehicles. Moreover, the technical routes of major companies are different, and the thermal management system architecture is also very different. The thermal management system needs to be specially designed according to the power system mechanism. [0003] The thermal management system of hybrid electric vehicles usually includes heat-generating components such as engine, power battery, charger, synthesis box, and motor controller. The...
