The thermal management system comprises an engine loop, a heating loop and a battery loop, and different on-off modes of a first three-way valve and a second three-way valve are controlled to be matched with a second pump body and a heater, so that the thermal management of the plug-in hybrid electric vehicle is achieved. Switching among a pure electric heating mode, a hybrid heating mode and a non-heating mode can be achieved, and the functions of passenger compartment heating, battery heating, engine waste heat utilization and the like are achieved; the engine loop is connected with the heating loop through a pipeline connecting piece with at least five connectors, and the flowing path of the connector of the engine oil cooler and the connector of the temperature control module and the flowing path of the connector of the second three-way valve and the connector of the second pump body are arranged in a staggered mode. Therefore, the air-conditioning refrigeration effect of the passenger compartment is improved to a certain extent, and the risk caused by the fact that the heat medium flows through the heat exchanger to heat the battery loop is avoided.
本申请公开了插电混合动力汽车热管理系统及热管理方法和汽车,该热管理系统包括发动机回路、制热回路和电池回路,通过控制第一三通阀和第二三通阀不同的通断模式,配合第二泵体、加热器,能够实现纯电制热模式、混动制热模式和非制热模式之间的切换,实现乘员舱采暖、电池加热、发动机余热利用等功能;发动机回路通过具有至少五个接口的管道连接件与制热回路连接,并且连接使机油冷却器与温控模块的接口的流动路径和连接第二三通阀的与第二泵体的接口的流动路径错位设置,可在不影响发动机进出口流量的前提下,切断制热回路的冷却液流动,一定程度上提升乘员舱的空调制冷效果,避免了热介质流过换热器加热电池回路产生的风险。
