Problems solved by technology

[0009] However, this implementation can exhibit sealing defects which can lead to poor heat exchange performance levels
[0010] In fact, poor control of the seal between the bundle and the intake manifold of the exchanger can lead to leaks between the bundle and the manifold, and thus cause a significant drop in performance
[0011] Also, the fixation of the exchanger in the header may not be effective enough

Embodiment Construction

[0039] The present invention relates to a heat exchanger. figure 1 Such a heat exchanger is shown, designated with the general reference numeral 1 .

[0040] Such an exchanger 1 can be used in particular for cooling charge air for a motor vehicle heat engine.

[0041] In this case, the exchanger 1 can be arranged in an air intake manifold 3, also called a feed gas distributor, as in figure 2 shown.

[0042] To this end, the manifold 3 may have side openings 4 which allow the exchanger 1 to be inserted therein. Assembly can be performed by inserting the exchanger 1 into the manifold 3 via the associated opening 4 of the manifold 3 , eg in the longitudinal direction of the exchanger 3 .

[0043] Manifold 3 is normally mounted on the cylinder head and allows charge air to enter the cylinder head.

[0044] The air intake manifold 3 and the exchanger 1 received in the manifold 3 form a charge air intake 5 .

[0045] In addition, the exchanger 1 may be an "air-water" exchanger...

Abstract

The present invention relates to a heat exchanger for heat exchange between at least two fluids, in particular for heat exchangers in motor vehicles, including a bundle for heat exchange between the fluids (7), and a housing for receiving the bundle (7), the housing (9) having at least one raised edge (11). Featured in the present invention, the exchanger further comprises a seal consisting of a hard plastic material (15), the seal encapsulates at least one raised edge (11) and is designed to ensure tightness between the exchanger and the container of the exchanger. The present invention further relates to an air intake device, comprising such a heat exchanger and an air intake header.

Description

field of invention [0001] The invention relates to a heat exchanger, in particular for a motor vehicle. The invention also relates to an air intake device comprising such an exchanger. Background technique [0002] Heat exchangers, such as those used in the automotive industry, comprise fluid heat exchange and flow elements in which fluids that exchange heat with each other are circulated. The heat exchange elements may for example comprise tubes or plates, fins and / or fluid flow disruptors interrupting gas circulation, or similar components. [0003] Such exchangers are known for use in the motor vehicle sector, especially for supercharged heat engines. [0004] In this case, the heat exchanger, also called Charge Air Cooler (RAS for short), makes it possible to cool the air from Charge air for the engine, thus forming an air / air or liquid / air type exchanger. [0005] In a conventional manner, air is received at the intake manifold (as it is commonly called by those ski...
