Embodiment Construction

[0037] In the following description, the same reference numerals are used to designate the same or similar elements.

[0038] as in figure 1 and 2 As illustrated in , the invention relates to heat exchangers, in particular for refrigerants circulated in motor vehicles.

[0039] Said exchanger comprises a first unit 1 for circulating a first fluid, and a second unit 2 for circulating a second fluid, said first unit defining first blades 3 for circulating said first fluid, Said second unit defines second vanes 4 for circulating said second fluid. The blades 3 , 4 are stacked in the stacking direction D of the blades so that heat exchange can take place between the first fluid and the second fluid.

[0040] The units 1 , 2 are formed, for example, from parts made of aluminum and / or aluminum alloys. They can be assembled, for example by brazing of the parts.

[0041] exist figure 1 In the above, the first unit 1 extends from the top to the bottom, and the second unit 2 exten...

Abstract

The invention relates to a heat exchanger, in particular for circulating a refrigerant in a motor vehicle, comprising a first unit (1) for circulating a first fluid and a second unit (1) for circulating a second fluid two units (2), said first unit defining first vanes (3) for circulating said first fluid, said second unit defining second vanes (4) for circulating said second fluid, wherein the blades (3, 4) are stacked in a stacking direction such that heat exchange can take place between the first fluid and the second fluid, and the units (1, 2) allow the circulation of the first fluid while avoiding the second fluid. second unit (2), and allows the second fluid to circulate while avoiding the first unit (1).

Description

technical field [0001] The invention relates to an exchanger. Although the exchanger is more specifically intended for application as an internal exchanger of an air-conditioning circuit or as an exchanger between a refrigerant and a heat transfer fluid, it can also be utilized more broadly for any type of fluid between two fluids. heat exchange. Background technique [0002] Various configurations of exchangers defining circulation blades for each fluid between which heat exchange needs to take place are known in the art. Particularly well known are brazed exchangers in which the blades are defined by stacked plates between which circulation blades are alternately defined. The blades for fluid circulation are joined together by connecting elements discharging in the area of ​​the channel openings, which are likewise arranged in the plate, in such a way that each fluid from its circulation blade One travels to the other without penetrating into the circulation blades of t...
