The invention relates to a heat exchanger (10, 20, 30, 40, 50), particularly a charge air heat exchanger or exhaust gas heat exchanger, for the heat exchange between a first fluid, particularly a charge air (3), or an exhaust gas, and a second fluid, particularly a coolant, comprising the following: heat exchanging guides for the first and second fluids, the guides being separated from each other in the block (1), the block (1) having a plurality of flow channels (5) through which the first fluid flows, and a housing (7, 37, 47, 57) that receives the flow channels (5) and through which the second fluid flows; at least one compartment lid (11, 11'), which is flow-connected to the flow channels (5), and a base (15, 15') that is attached to the compartment lid (11, 11') and that is equipped with one or more passage openings (17) for flow channels (5). In order to achieve an advantageous connection of the compartment lid (11, 11') to the base (15, 15'), particularly in case the compartment lid (11, 11') and the base (15, 15') are made of different materials, the invention provides that the compartment lid (11, 11') is attached to the base (15, 15') via one or more connections as a bolted connection (19) and/or a slotted crimping (26).

The invention relates to a heat exchanger (1) comprising fixing elements which are provided with points of fracture, in particular in a vehicle. The aim of said invention is to provide said heat exchanger with restorable points of fracture and to make it possible to easily reassemble them after the separation thereof. For this purpose, the inventive heat exchanger (1) is characterised in that at least one fixing element is provided with a first and second area (6, 7; 12, 14) and with a quick release coupling therebetween; two areas (6, 12) form an inseparable component of the heat exchanger (1); the two areas (6, 7; 12, 14) are fixable to each other by a positive connection when the quick release coupling is closed; the coupling systems of one of the areas (6, 7; 12, 14) are provided with at least one point of fracture and in that the coupling systems provided with at least one point of fracture are arranged on the area (7, 14) which a detachable from said heat exchanger.
