Abstract: A housing for at least one heat-releasing element (100), for example a battery element in an electric vehicle, comprises: a housing wall (200), a holder (300) which is joined to the housing wall (200) for accommodating the at least one heat-releasing element (100) and a cooling body (400) which is arranged on a side of the housing wall (200) opposite the holder (300) and is joined to the housing wall (200). The housing wall (200), the holder (300) and the cooling body (400) are together present as one-piece component, wherein the cooling body (400) has at least one channel (500) for a cooling medium and at least a subregion of the cooling body (400) consists of a first thermoplastic polymer composition having a thermal conductivity determined in accordance with ASTM E1461-01 of ?0.2 W/(m K).
