Abstract

A cooling system for a battery is provided which includes a first tube, a second tube and a middle section which may be formed from an electrically insulating yet thermally conductive material. The first tube and the second tube may each be adapted to transfer coolant from a first end to a second end. The middle section integral may be the first tube on the first side of the middle section and integral to the second tube on the second side of the middle section. The first tube, the second tube and the middle section may be operatively configured to draw thermal energy away from at least one bus bar and corresponding cell tabs for a battery.

First claim

What is claimed is:

1. A cooling system for a battery comprising:
a first tube adapted to transfer coolant;
a second tube adapted to transfer coolant; and
a middle section integral to the first tube on the first side of the middle section and integral to the second tube on the second side of the middle section, the middle section defines a plurality of openings and is disposed adjacent to only one side of a battery cell
wherein each opening in the plurality of openings is operatively configured to accommodate a pair of cell tabs from the battery cell so that the first tube and the second tube are both disposed perpendicular to each pair of cell tabs extending out of each opening.

2. The cooling system as defined in claim 1 wherein the middle section is formed from an electrically insulating yet thermally conductive material which is injection molded onto the first and second tubes.

3. The cooling system as defined in claim 2 wherein the first tube and the second tube are formed from aluminum.

4. The cooling system as defined in claim 2 wherein the first tube and the second tube are each adapted to receive coolant at a first end.

5. The cooling system as defined in claim 4 wherein the first tube and the second tube are each adapted to purge coolant at a second end.
