The invention discloses a thermal management method and device for a thermal management system of a liquid hydrogen heavy truck, and the method comprises the steps that the real-time temperature of target equipment in the thermal management system of the liquid hydrogen heavy truck is detected, and the target equipment at least comprises one of a hydrogen fuel engine, a cab warm air core body and a power battery; and when the real-time temperature of the target equipment meets the preset temperature condition, the liquid hydrogen heavy truck thermal management system is controlled to enter a corresponding thermal management mode by adjusting a cooling liquid circulating flow path in the liquid hydrogen heavy truck thermal management system. By adjusting the multiple control valves, waste heat of the hydrogen fuel engine is fully utilized, and the heating requirements of a power battery and a cab can be met; the liquid hydrogen in the liquid hydrogen vaporization device is rapidly vaporized through the arrangement of the cold energy recovery branch, cooling of cooling liquid is accelerated through the vaporization heat absorption process, then the heat dissipation load of an engine heat dissipation module is reduced, the energy consumption of the whole vehicle is reduced, and the economical efficiency is improved.
本申请公开了一种液氢重卡热管理系统的热管理方法、装置,包括:检测液氢重卡热管理系统中目标设备的实时温度,其中目标设备至少包括如下之一:氢燃料发动机、驾驶室暖风芯体、动力电池;当目标设备的实时温度满足预设温度条件时,通过调节液氢重卡热管理系统中的冷却液循环流动路径,以控制液氢重卡热管理系统进入对应的热管理模式。本申请通过调节多个控制阀的方式,将氢燃料发动机余热充分利用,能够满足动力电池的加热以及驾驶室的采暖需求;通过设置冷量回收支路,使得液氢汽化装置中的液氢快速完成汽化,而且还利用汽化吸热过程加快了冷却液自身的冷却,进而减小了发动机散热模块的散热负荷、降低了整车的能耗,提高了经济性。
