Abstract
A temperature control device for individual battery cells (2) assembled to form a module (1), having a base body (3) which, for the purpose of circumferentially enclosing the battery cells (2), comprises two opposing sealing elements (4, 5) having passage openings (6) located opposite one another in pairs with respect to a respective joining axis, and which base body (3) forms a flow channel extending transversely to the joining axes for a temperature control fluid is described. In order to design a temperature control device of the type described above in such a way that, with less manufacturing effort, an increased tightness of the device is achieved at the same time, even at higher flow rates of the temperature control fluid, it is proposed that the sealing elements (4, 5) are two moulded parts which are identical to one another and which are aligned point-symmetrically with respect to one another and connected to one another and which sealing elements (4, 5) form via a respective bearing surface (7) the base body (3), wherein a receiving groove (9) having a seal compensation region (8) adjoins the bearing surface (7) on the inside of the base body (3).
