Problems solved by technology

[0006] In the case of conventional side parts, in the event of a side fracture due to thermally induced longitudinal expansion of the tube body, parts of the side part may detach from the heat exchanger and may cause damage in the engine compartment of the corresponding motor vehicle even destroys and is therefore unfavorable

Embodiment Construction

[0040] In the three-dimensional part diagram, figure 1 An example of a heat exchanger 1 according to the invention is shown in figure 1 The example is presented as an intercooler. The heat exchanger 1 includes a plurality of tube bodies 2 which are stacked on each other along a stacking direction S and through which a coolant (not shown) can flow. The heat exchanger 1 further comprises a bottom 3, in figure 1 In the assembled state of the heat exchanger shown, the tube body 2 with the longitudinal ends 5 can be welded to the bottom 3 . A coolant distributor 4 is also attached to the bottom 3 via which coolant can be distributed to the individual tubes 2 . On the longitudinal end of the tube body 2 opposite the coolant distributor 4 there may similarly be provided a further bottom (not shown) to which a coolant collector (also not shown) may be attached in a similar manner. Coolant distributors 4 and not shown coolant collectors can be crimped to the respective base 3 .

Abstract

The invention relates to a heat exchanger, in particular for motor vehicles, comprising a plurality of tubes arranged between two sides. At least one side has at least one predetermined breaking point and at least one thermal expansion compensator. Additionally, at least one hole is provided in said side portion, which leads from said predetermined breaking point to said at least one thermal expansion compensator.

Description

technical field [0001] The invention relates to a heat exchanger for a motor vehicle and to a heat exchanger comprising such a heat exchanger. Background technique [0002] Conventional heat exchangers used as coolant coolers or intercoolers in motor vehicles typically include a plurality of tubes through which coolant can flow. The tubes are stacked on top of each other and are welded to one or more bottoms during assembly of the heat exchanger and are fixed relative to each other in this way. To facilitate the welding process, the tube is often arranged between two sides for laterally stabilizing the tube during welding. Such sides are usually made of a suitable light metal, such as aluminum, and are rendered sufficiently rigid to ensure the desired stability of the pipe body. Said sides are only used for the installation of the heat exchanger, not during operation of the heat exchanger and therefore not after assembly of the heat exchanger. However, the sides are usual...
