A filter arrangement may include a filter element and a gasket element. The gasket element may include a substantially circular flow-through opening and a locking collar. The locking collar may be arranged along a circumference of the flow-through opening with respect to a circumferential direction. The locking collar may form a hollow cylindrical installation space. The filter element may include a filter element body and a substantially hollow-cylindrical counter locking collar. The counter locking collar may include an open axial side and a covered axial side which may be spaced apart from each other with respect to an axial axis. The covered axial side of the counter locking collar may be covered by said filter element body. The counter locking collar may be at least partially inserted into the hollow cylindrical installation space of the locking collar.

A heat exchanger may include an outer casing extending in a longitudinal direction and delimiting a volume through which a first fluid is flowable, and a tube bundle including a plurality of tube bodies arranged in the volume and through which a second fluid is flowable. In a cross section, the volume may have an inner surface area and an inner circumference and each tube body may have an outer circumference and an outer surface area. A ratio of a sum of the outer circumferences to the inner circumference may be at least 5.5, and a sum of the outer surface areas may account for 64% or less of the inner surface area. A residual cross section area of the inner surface area may be delimited between the outer casing and the plurality of tube bodies.
