HEAT EXCHANGER FLUID DISTRIBUTION MANIFOLD AND POWER ELECTRONICS MODULE INCORPORATING THE HEAT EXCHANGER FLUID DISTRIBUTION MANIFOLD

摘要

PROBLEM TO BE SOLVED: To provide a heat exchanger fluid distribution manifold which uniformly distributes a coolant fluid to a heat exchanger, and to provide a power electronics module incorporating the heat exchanger fluid distribution manifold.

SOLUTION: The heat exchanger fluid distribution manifold 100 comprises: a manifold body 102 which defines a coolant fluid chamber 105; a single fluid inlet 110 which is configured to introduce the coolant fluid into the chamber; and a plurality of fluid outlets 120 which are configured to remove the coolant fluid from the chamber. At least two of the fluid outlets are separated from the single fluid inlet by an unequal distance, and a coolant fluid flow rate at each fluid outlet is substantially uniform. The heat exchanger fluid distribution manifold further comprises a plurality of serpentine walls along the coolant fluid chamber. Each serpentine wall comprises a spline feature located proximate to an individual fluid outlet. The spline features are optimized such that the coolant fluid flow rate is substantially uniform and a total pressure drop is less than about 2 kPa.
