1. A heat exchanger comprising:
a first plate, a second plate, and a perforated plate having a plurality of openings, the perforated plate sandwiched between the first plate and the second plate;
the first plate having:
a first plate central planar surface having an internal face and an opposing external face;
a first plate peripheral wall having a first end and a second opposing end, the first plate peripheral wall coupled at or extending from the first end to and extending from a peripheral edge of the internal face of the first plate central planar surface; wherein the first plate central planar surface and the first plate peripheral wall together define an inlet chamber; and
an inlet permitting fluid flow on to the internal face of the central planar surface; and
the second plate having:
a second plate central planar surface having an internal face and an opposing external face;
a second plate peripheral wall having a first end and a second opposing end, the second plate peripheral wall coupled at or extending from the first end to and extending from a peripheral edge of the internal face of the second plate central planar surface, the second plate peripheral wall extending towards the first plate; wherein the second plate central planar surface and the second plate peripheral wall together define an outlet chamber; and
an outlet permitting fluid to exit from the heat exchanger;
wherein the first plate and the second plate are in a face to face relation with the first plate internal face facing the second plate internal face, and wherein the first plate, the second plate, and the perforated plate are coupled and define a fluid passage for flow of a heat exchanger fluid from the inlet to the outlet, and wherein the second plate is in contact with a plurality of battery cells,
wherein the perforated plate has a plurality of nozzles, and each nozzle has an opening, to provide the plurality of openings.
