Thermal management system for an electrochemical engine

摘要

A thermal management system for an electrochemical engine (16) in a vehicle comprises a coolant pump (64) and a radiator (66). The radiator is oriented substantially parallel to a plane defined by longitudinal and lateral vehicle axes and defined by an inlet face as the upper surface and an outlet face as the lower surface. The radiator is packaged in a rear underbody compartment of the vehicle to allow a large cooling surface area. An air duct (84) delivers air from outside the vehicle to the inlet face of the radiator. A fan (67) forces air from the air duct through the radiator. A coolant circuit extends between a fuel cell stack of the electrochemical engine, the coolant pump, and the radiator.
