Abstract
A cooling plate design for cooling a battery cell is provided that employs a plastic plate having cutouts for coolant flow paths. The plastic plate has a layer of adhesive film on each side to maintain coolant in the channels. Compression within an alternating battery cell and coolant plate stack provides pressure that minimizes coolant load on the film. Methods to manufacture the cooling plate are also provided.
Claims12
A cooling plate comprising:
- a substantially planar plate having a first surface, a second surface, and a cutout, the cutout including an inlet, an outlet, and a flow field between the inlet and the outlet;
- wherein the inlet and the outlet are disposed on a respective exterior edge surface of the substantially planar plate, between the first surface and the second surface;
- a first film coupled to the first surface;
- a second film coupled to the second surface, wherein the flow field, the first film, and the second film cooperate to form at least one conduit fluidly coupling the inlet and the outlet;
- and
- wherein the first film includes an adhesive bonding the first film and the first surface of the substantially planar plate together, and the second film includes an adhesive bonding the second film and the second surface of the substantially planar plate together, with the adhesive bond between the first film and the first surface and between the second film and the second surface providing a fluid tight seal therebetween to prevent leakage of coolant between the first film and the first surface of the planar plate, and between the second film and the second surface of the planar plate respectively.
