Thermal management system for fuel cell vehicles

摘要

A thermal management system is provided which may be miniaturized and may have a reduced weight by integrating thermal management parts in a fuel cell vehicle. In particular, a new type of thermal management system integrated housing in which a housing of a pump housing part, a housing of a 3-way valve fluid part, and a bypass channel among parts of the thermal management system for a fuel cell vehicle are integrated into a single structure to reduce the size of the overall system.

1. A thermal management system for a fuel cell vehicle, comprising:
a radiator configured to cool a fluid; a fluid line configured to circulate the fluid between the radiator and a fuel cell stack; a bypass channel configured to bypass the fluid; a pump configured to circulate the fluid; a 3-way valve configured to switch a fluid path between the fluid line and the bypass channel; and a thermal management system (TMS) integrated housing formed as a single body consisting essentially of: a pump housing part connected to a fluid inlet and a fluid outlet which are connected to an outlet of the fuel cell stack and an inlet of the radiator, respectively, a 3-way valve housing part connected to the fluid inlet and the fluid outlet which are connected to an outlet of the radiator and an inlet of the fuel cell stack, and the bypass channel connecting between the pump housing part and the 3-way valve housing part.
