Patent Images
1. A battery cell assembly, comprising:
- a cooling fin having a generally rectangular-shaped aluminum plate, a tube, and a flexible thermally conductive graphite sheet;
the generally rectangular-shaped aluminum plate having a first side and a second side;
the generally rectangular-shaped aluminum plate defining at least first, second, third, and fourth arcuate-shaped peripheral edge portions;
the tube coupled to the first side of the generally rectangular-shaped aluminum plate, the tube being disposed on the first, second, third, and fourth arcuate-shaped peripheral edge portions of the generally rectangular-shaped aluminum plate in an arcuate-shaped groove defined by the first, second, third, and fourth arcuate-shaped peripheral edge portions;
the flexible thermally conductive graphite sheet having an adhesive disposed on one side of the flexible thermally conductive graphite sheet, the adhesive being further disposed on the first side of the generally rectangular-shaped aluminum plate to couple the flexible thermally conductive graphite sheet to the first side; and
a battery cell disposed against the flexible thermally conductive graphite sheet of the cooling fin.

Abstract
A battery cell assembly is provided. The battery cell assembly includes a cooling fin having a rectangular-shaped aluminum plate, a tube, and a flexible thermally conductive sheet. The plate has a first side and a second side. The tube is coupled to the first side of the plate and extends on at least first, second, and third peripheral edge portions of the plate. The flexible thermally conductive sheet is disposed on the first side of the plate. The battery cell assembly further includes a battery cell disposed against the flexible thermally conductive sheet of the cooling fin.

9. A battery cell assembly, comprising:
-
a cooling fin having a generally rectangular-shaped aluminum plate, a tube, and a flexible thermally conductive sheet, the flexible thermally conductive sheet including graphite therein; the generally rectangular-shaped aluminum plate having a first side and a second side and having a substantially uniform thickness between the first side and the second side;
the generally rectangular-shaped aluminum plate defining at least first, second, and third arcuate-shaped peripheral edge portions;the tube coupled to the first side of the generally rectangular-shaped aluminum plate, the tube being disposed on the first, second, and third arcuate-shaped peripheral edge portions in an arcuate-shaped groove defined by the first, second, and third arcuate-shaped peripheral edge portions; the flexible thermally conductive sheet being directly coupled to the first side of the generally rectangular-shaped aluminum plate such that first, second, and third ends of the flexible thermally conductive sheet are disposed proximate to first, second, and third tube portions, respectively, of the tube; and a battery cell disposed against the flexible thermally conductive sheet of the cooling fin. - View Dependent Claims (10, 11, 12, 13)
