Problems solved by technology

However, these holes cause air to leak, which results in a loss of pressure, which is synonymous with loss of performance
[0006] Furthermore, the use of teeth or clips arranged on the outward edge requires oversizing of the outer packaging due to the excessive thickness caused by the teeth or clips

Embodiment Construction

[0025] Refer below Figures 1 to 5 A heat exchanger 1 according to the invention is described.

[0026] The heat exchanger 1 comprises an exchange bundle 2 and a bundle shell 3 accommodating the exchange bundle 2 . The bundle housing 3 is made in at least two housing parts 34a-34d and substantially defines a hollow parallelepiped, one face of which is open (open face 31), so that the four adjacent faces 32a-32d form the outer A joint boundary 33 of a part of the surface forms an end edge delimited on the outer surface of the housing. This outer surface is generally formed by the faces of the housing parts 34a-34d rather than by their edges. The term “housing parts” is used within the scope of this description to denote parts that have been assembled and then fastened together to form the beam housing 3 . Therefore, they are not integrally formed with each other. The bundle housing 3 may also have a further open face 31 opposite this first open face 31, so that four adjacen...

Abstract

The invention relates to a heat exchanger (1) comprising a bundle of heat exchanging cores (2) and a core housing, which essentially defines a hollow parallelepiped, one face (31) of which is open so that four adjacent faces pass through The joint edge forms an end edge delimited on the outer surface of the shell, said core shell being made into at least two shell parts (34a-34d); characterized in that said joint edge has rounded corners, the shell parts (34a-34d) are arranged such that at the joint edge the outer surface of one substantially continues the outer surface of the other.

Description

technical field [0001] The invention relates to the technical field of devices for motor vehicles, in particular air supply devices for engines of motor vehicles, more particularly for engines whose air supply originates from a compressor or a turbocharger. Background technique [0002] The supply air from the compressor or turbocharger is also called "charge air". [0003] In order to increase the charge air density of a turbocharged engine, it is known to cool the charge air leaving the compressor by means of a heat exchanger, also known as a charge air cooler. [0004] Charge air coolers usually include exchange bundles. The exchange bundle comprises a stack of plates or tubes which alternately form circulation channels for the charge air to be cooled and channels for the circulation of a heat transfer fluid, in particular engine coolant. The heat exchange between the plates or tubes and the charge air takes place partly via turbulators. The bundle is enclosed in a con...
