Vehicle heat management system and vehicle

Abstract

The invention relates to a vehicle heat management system and a vehicle. The vehicle heat management system comprises an engine cooling loop, an air conditioner heating loop and a fluid switching device, an engine, a first water pump and a first radiator are arranged on the engine cooling loop, a heater, a second water pump and a warm air core body are arranged on the air conditioner heating loop,the engine cooling liquid loop is connected with the air conditioner heating loop through the fluid switching device, and the fluid switching device is used for controlling the engine cooling loop and the air conditioner heating loop to be selectively independent of each other or be in fluid communication with each other. According to the vehicle heat management system, fluid connection can be established between the engine cooling loop and the air conditioner heating loop, so that waste heat of the engine is reasonably utilized for heating the passenger compartment, the utilization rate of whole vehicle energy can be increased, and whole vehicle energy loss is reduced.

Description

technical field [0001] The present disclosure relates to the field of thermal management of vehicles, in particular, to a vehicle thermal management system and a vehicle. Background technique [0002] In the heat management system of a hybrid electric vehicle, the engine cooling circuit is usually independent of other heat management circuits. Therefore, the heat generated by the engine is dissipated to the outside through the radiator in the cooling circuit, resulting in waste of heat. Air-conditioning thermal management systems and battery thermal management systems usually only rely on heaters for heating, which has a large energy consumption burden, and the heating efficiency of the passenger compartment and batteries is low. Contents of the invention [0003] The purpose of the present disclosure is to provide a vehicle thermal management system and a vehicle, the vehicle thermal management system can rationally utilize the heat of the engine, improve the utilization ...
