Abstract

An integrated pumping module for use in a thermal management system, for example for a fuel cell. The integrated pumping module includes a diverting or mixing valve closely coupled to a pump element, such as the volute chamber of a centrifugal pump. The valve chamber and the pump chamber are closely and directly coupled through a connecting passage so as to minimize pressure drop as a liquid coolant passes through the connecting passage from the valve chamber to the pump chamber. A bypass inlet and outlet opening are provided in the valve chamber to permit all or a portion of the coolant flow to be diverted to a radiator once the coolant reaches a predetermined temperature. The integrated pumping module may also be provided with a filter housing into which a portion of the coolant flow may be diverted.
