Cooling device for power electronics, has pin-fin array extending from foot point of base body, and pins continuously tapered from proximate end to distal end of foot point in cone form or truncated cone form

摘要

The device (2) has a pin-fin array (5) extending from a foot point (6) of a base body (1). Pins (7) are continuously tapered from a proximate end (7a) of the foot point to a distal end (7b) of the foot point in a cone form or truncated cone form. A coolant flowpath is formed between a cooling fluid inlet and a cooling fluid outlet. The pin is formed under an outlet jam edge in an outlet region (15) of a rectangular housing of the base body. The cooling fluid outlet is in fluid communication with the pin.
