SERIES COOLED MODULE COOLING FIN

An automotive battery module with numerous battery cells and a series-based cooling fin arrangement placed in thermal communication with at least two of the battery cells. Heat generated within the battery cells by, among other things, electric current that can be used to provide motive power for the automobile, may be removed by the cooling fin that includes different portions tailored to remove relatively lesser or greater amounts of heat, depending on a potential temperature difference among the cells. The construction of the cooling fin is such that multiple heat transfer paths are established, each configured to convey heat away from the battery cells, as well as to keep temperature differences between adjacent series-cooled battery cells to a minimum. In one form, the multiple heat transfer paths may include a relatively laminar portion and a relatively turbulent portion, where in one form the increased turbulence may be obtained through numerous turbulators. Other such heat transfer paths may include an intermediate exhaust path, a discreet coolant channel or the like. Any or all of the turbulators, exhaust path or discreet coolant channel may be tuned in order to increase or decrease an amount of heat delivered to the cooling fin from the battery cells.
