TEMPERATURE-CONTROL DEVICE FOR INDIVIDUAL BATTERY CELLS WHICH ARE COMBINED INTO A MODULE

The invention relates to a temperature-control device for individual battery cells (2) which are combined into a module (1), comprising a main part (3) which has passage openings (4) lying opposite each other in pairs for each joining axis in order to surround the periphery of the battery cells (2) and which forms a flow channel running transversely to the joining axes for a temperature-control fluid. The main part (3) comprises at least one temperature-control fluid connection (5) which runs in the direction of the joining axes. The aim of the invention is to design a temperature-control device of the aforementioned type such that an operating temperature window of a few degrees Celsius is achieved despite high electric loads and a compact design. This is achieved in that the main part (3) has a flow splitter (6) which lies opposite the temperature-control fluid connection (5) in the direction of the joining axes and which forms inflow surfaces (7) for splitting the temperature-control fluid flow into individual sub-flows and for a substantially tangential inflow against the adjacent battery cells (2).
