HEAT EXCHANGER WITH INTERNAL COLD FLUID DISTRIBUTION FEATURES FOR COOLING MULTIPLE ROWS OF BATTERY CELLS
First Claim
1. A heat exchanger having a length and a width and comprising a plurality of flow sections separated by flow barriers;
- wherein each said flow section has a first end and a second end spaced apart along the length of the heat exchanger;
wherein the flow sections are arranged side-by-side along the width of the heat exchanger and adjacent pairs of said flow sections are in flow communication with each other through openings in said flow barriers;
wherein said plurality of flow sections includes an inlet flow section, an outlet flow section, and at least first and second intermediate flow sections between the inlet flow section and the outlet flow section;
wherein the heat exchanger further comprises;
an inlet port in flow communication with a first end of the inlet flow section;
an outlet port in flow communication with the outlet flow section; and
a first bypass channel extending between the inlet port and at least one of the intermediate flow sections.

Abstract
A heat exchanger for cooling multiple rows of battery cells has a plurality of longitudinal flow sections defining at least first and second U-shaped flow areas, each underlying a row of battery cells. The flow sections includes inlet and outlet flow sections, and at least two intermediate flow sections. Inlet and outlet ports are in flow communication with the respective inlet and outlet flow sections, and a first bypass channel extends between the inlet port and at least one of the intermediate flow sections. The first bypass channel supplies relatively cold heat transfer fluid from the inlet to mix with warmer fluid in a second or subsequent U-shaped flow area, to improve temperature uniformity between the rows of battery cells. A second bypass channel may extend around the outer periphery of the heat exchanger, from the inlet flow section to a second or subsequent U-shaped flow area.
