燃料电池重卡热管理研究

Research on Cooling System of Heavy Duty Truck with Hydraulic Retarder

燃料电池重卡包含电堆热管理、电池热管理和电机冷却等三套热管理子系统,根据各子系统的温度限值、散热需求和热管理方式,分析了燃料电池重卡整车热管理的基本组成和各子系统的基本原理、基本构造、特点和控制逻辑等,为后续燃料电池重卡的热管理研究提供了依据。

Fuel cell heavy truck includes three sets of thermal management subsystems, such as fuel cell thermal manage -ment system, battery thermal management system and motor cooling system. According to the temperature limit, thermal dissipation requirement, and thermal management mode of each subsystem, analyse the basic composition of the vehicle thermal management and the basic principle, basic structure, characteristics and control logic of each subsystem, which provides a basis for the research on thermal management of fuel cell heavy truck.
