Abstract
A cold plate heat exchanger for battery thermal management has first and second plates defining a plurality of fluid flow passages, with inlet and outlet ports proximate to a first end thereof. Each fluid flow passage has first and second ends communicating with respective inlet and outlet ports. One or more portions of each fluid flow passage are immediately adjacent to and in close proximity to a portion of another fluid flow passage or channel, such that heat energy will be transferred by conduction through the first and second plates between the fluid flow passages or channels, thereby providing enhanced heat transfer. The fluid flow passages or channels may be separated by a distance which is less than a width of one of the fluid flow passages or channels, and may be separated by a single rib which partially defines each of the fluid flow passages or channels.
