Abstract: An air cleaner of an internal combustion engine has a housing with a slide-in opening and receives a slide-in filter element through this opening. A cover element closes off the slide-in opening. The cover element has a snap element for fixing the cover element at the housing. The cover element has a contact face defining a first main plane. A sealing is disposed between the filter element and the housing and seals between filter element and housing. A sealing face provided at the housing interacts with the sealing and defines a second main plane. The housing has a contact face abutting the contact face of the cover element in the closing state of the cover element. An angle between the second main plane of the sealing face of the housing and the first main plane of the contact face of the cover element is different from 90°.

Abstract: Disclosed is a heat transfer module (3) for battery cells includes a plastic frame (4) having a supply conduit and an exhaust conduit (13b) for a heat transfer fluid. Two heat transfer members (12a, 12b) contacting a respective battery cell. The heat transfer members (12a, 12b) are sealingly attached to opposite faces of the frame (4), and at least one heat transfer channel (15) formed between the frame (4) and one of the heat transfer members (12b) transporting the heat transfer fluid from the supply conduit to the exhaust conduit (13b). Also disclosed is a battery assembly having a plurality of such heat transfer modules (3).
