Claim:
1. A battery cell assembly, comprising: a cooling fin having a tube and a flexible thermally conductive graphite sheet disposed on the tube; the tube having first, second, and third tube portions fluidly communicating with one another, the first and second tube portions being substantially parallel to one another, the third tube portion being substantially perpendicular to the first and second tube portions and extending between the first and second tube portions; the flexible thermally conductive graphite sheet having first, second, and third sheet portions; the flexible thermally conductive graphite sheet further having a first side and a second side; the third sheet portion being coupled to and extending between the first and second sheet portions, the first and second tube portions being disposed on the first and second sheet portions, respectively, on the first side of the flexible thermally conductive graphite sheet; a first plastic C-shaped clamping member contacting the first tube portion and the first sheet portion on the second side of the flexible thermally conductive graphite sheet to clamp the first sheet portion to the first tube portion, a length of the first plastic C-shaped clamping member being less than one-fifth of a length of the first tube portion; a second plastic C-shaped clamping member contacting the first tube portion and the first sheet portion on the second side of the flexible thermally conductive graphite sheet to further clamp the first sheet portion to the first tube portion, the second plastic C-shaped clamping member being separated from and disposed away from the first plastic C-shaped clamping member a first distance, a length of the second plastic C-shaped clamping member being substantially equal to the length of the first plastic C-shaped clamping member; a third plastic C-shaped clamping member contacting the second tube portion and the second sheet portion on the second side of the flexible thermally conductive graphite sheet to clamp the second sheet portion to the second tube portion, a length of the third plastic C-shaped clamping member being less than one-fifth of a length of the second tube portion; a fourth plastic C-shaped clamping member contacting the second tube portion and the second sheet portion on the second side of the flexible thermally conductive graphite sheet to further clamp the second sheet portion to the second tube portion, the fourth plastic C-shaped clamping member being separated from and disposed away from the third plastic C-shaped clamping member a second distance, a length of the fourth plastic C-shaped clamping member being substantially equal to the length of the third plastic C-shaped clamping member; a battery cell disposed against the third sheet portion of the flexible thermally conductive graphite sheet; and first and second frame members being coupled together that hold the cooling tin and the battery cell therebetween.
