Abstract

A thermal cycle management system for a vehicle fuel cell includes a stack cooling circuit, a cabin heating circuit, and a controller; the stack cooling circuit includes a first water pump, a deionization and filter assembly, a stack, and a cabin heat exchanger. The first water pump is arranged on a main loop of the stack cooling loop and used for providing circulating power for the galvanic pilecooling loop; the deionization and filter assembly is connected in series behind the first water pump and is used for removing ions and impurities in the cooling liquid; the stack is connected in series behind the deionization and filter assembly and is used for generating electric energy; the cabin heat exchanger is connected in series behind the stack and used for exchanging a part of heat generated by the stack to the cabin heating loop. According to the thermal cycle management system of the vehicle fuel cell, an integrated scheme of integrating the ion exchanger and the cooling liquid filter is adopted, the system performance is guaranteed, and the number of parts is reduced.

Description

technical field [0001] The invention relates to the technical field of thermal management of fuel cells in the field of new energy vehicles, in particular to a thermal cycle management system of fuel cells for vehicles. Background technique [0002] Fuel cells have developed rapidly in recent years. They are superior to internal combustion engines in terms of system efficiency and emissions, and are superior to pure electric vehicles in driving range. It is expected that they will be widely used in vehicles with medium and long driving ranges in the future. [0003] The thermal management scheme of the existing fuel cell technology is usually composed of two parts, which are figure 1 The cabin heating circuit in the middle dotted box and the fuel cell cooling system circuit outside the dotted box. [0004] Fuel cell cooling system circuit: After the coolant flows out through the water pump, one way passes through the intercooler to cool the intake air, and the other way pas...
