Abstract

The invention relates to a cooling element, which is designed and equipped in particular to be disposed between electrochemical energy storage cells, comprising a heat exchanger structure through which a heat transfer medium can flow and which is formed at least substantially of two film layers or film layer structures, the opposing surfaces of which are placed against one another and which are connected at junctures within the surfaces, wherein the junctures define cavities between the surfaces, wherein the heat transfer medium can be conducted through said cavities.

Description

technical field [0001] The invention relates to a cooling element, in particular to a cooling element installed between electrochemical energy storage battery cells and a manufacturing method of the cooling element. The invention also relates to an electrochemical energy storage device comprising a cooling element in each case between two energy storage cells. Background technique [0002] FR 2 694 136 A1 discloses a cooling element mounted between flat stacked battery cells in a battery pack. The cooling elements are used as heat exchange plates, they are composed of parallel metal plates with pipes installed between them or corrugated metal sheets installed between them, the corrugated metal sheets are used to form a Coolant channels through which the coolant circulates. The battery pack comprises three cooling elements, two of each at the front and one in the center of the stack between two battery cells. The cooling element is designed and arranged for cooling with ai...
