The invention relates to the technical field of fuel cell vehicles, and particularly discloses an integrated heat management system, and a first heat exchange module can realize series integrated heat dissipation of a high-voltage distribution box, a driving motor and a fuel cell engine on a whole vehicle. The second heat exchange module can recycle waste heat generated when the fuel cell engine works to heat the cockpit; or waste heat generated by the cab air conditioner is used for preheating the fuel cell engine, so that waste of heat energy is avoided, and energy consumption is reduced. And the third heat exchange module coordinately controls residual cold generated when the whole vehicle condenser and the cab air conditioner are in a refrigeration mode to cool the power battery, so that the loss of cooling capacity is reduced. According to the integrated heat management system, heat management cooperative control over all high-power components of the whole vehicle is achieved, waste of waste heat and waste cold is avoided, the number of heat management components and the number of whole vehicle pipelines are reduced while energy consumption is reduced, and the whole vehicle cost is reduced. The invention further provides a fuel cell commercial vehicle which comprises the integrated heat management system.
本发明涉及燃料电池汽车技术领域,具体公开了一种集成式热管理系统,其第一换热模块能够实现整车上高压配电盒、驱动电机和燃料电池发动机的串联集成散热。第二换热模块可回收燃料电池发动机工作时产生的余热对驾驶舱进行加热;或将驾驶室空调产生的余热对燃料电池发动机进行预热,避免了热能的浪费,有利于节约能耗。第三换热模块协调控制整车冷凝器和驾驶室空调制冷模式时产生的余冷对动力电池进行降温,减少冷量的损耗。该集成式热管理系统实现对整车各高功率部件的热管理协同控制,避免了余热、余冷的浪费,节约能耗的同时减少热管理部件及整车管路数量,整车成本降低。本发明还提供一种燃料电池商用车,包括上述集成式热管理系统。
