Heat exchangers for battery thermal management applications with integrated bypass
First Claim
1. A heat exchanger for battery thermal management applications, comprising:
- a heat exchanger core defining at least one internal, two-pass flow passage, the at least one internal, two-pass flow passage having an inlet end, an outlet end, at least a first flow passage portion and at least a second flow passage portion, the first and second flow passage portions being interconnected by a generally U-shaped turn portion;
an inlet manifold in fluid communication with said inlet end of said internal flow passage for delivering an incoming fluid stream to said heat exchanger;
an outlet manifold in fluid communication with said outlet end of said internal flow passage for discharging an outgoing fluid stream from said heat exchanger; and
at least one bypass passage fluidly interconnecting said incoming fluid stream and said outgoing fluid stream, said at least one bypass passage allowing fluid from the incoming fluid stream to be diverted to said outlet manifold, at least partially bypassing said at least one internal, two-pass flow passage of said heat exchanger.

Abstract
A heat exchanger for battery thermal management applications is disclosed. The heat exchanger has at least one internal, two-pass flow passage, the at least one internal, two-pass flow passage having an inlet end and an outlet end and at least a first flow passage portion and at least a second flow passage portion interconnected by a generally U-shaped turn portion. An inlet manifold is in fluid communication with the inlet end of the internal flow passage for delivering an incoming fluid stream to the heat exchanger while an outlet manifold is in fluid communication with the outlet end of the internal flow passage for discharging an outgoing fluid stream from the heat exchanger. A bypass passage fluidly interconnects the incoming fluid stream and the outgoing fluid stream.
