Problems solved by technology

[0006] However, prior art headers do not allow sufficient reduction of the tube spacing to accommodate more tubes to increase the thermal efficiency of the heat exchanger
Therefore, the prior art headers do not support the heat exchanger for optimum thermal performance
[0007] Moreover, since this head includes a large number of reinforcing ribs arranged on the header to ensure that it can withstand the internal pressure of the heat exchanger, this solution of the prior art is complicated, the manufacturing cost is high, and the heat transfer is increased. The total mass of the device

Embodiment Construction

[0029] Please refer to figure 1 , shows a head 10 for a heat exchanger of a motor vehicle. In this example, the heat exchanger is a radiator provided with a row of heat exchange tubes 12 for conducting a heat transfer fluid into the heat exchanger. Alternatively, the heat exchanger may be another type of heat exchanger, such as a charge air cooler.

[0030] The head is configured to receive the heat exchanger tubes 12 by its ends 14 and to be assembled with a header 16 . In this example, the head 12 is composed of a metal plate 18, a sealing gasket 20 and a plate 22 made of polymeric material (hereinafter referred to as polymeric material plate).

[0031] The tube 12 is intended to pass through a metal plate 18 crimped to the header 16 . To this end, the metal plate 18 is a deep-drawn sheet comprising a central rectangular face 24 with regularly spaced oval openings for the passage of the tubes 12 . The sheet metal 18 has sides forming longitudinal folds 26 and transverse ...

Abstract

The invention relates to a header (10) for a heat exchanger of a motor vehicle, designed to receive heat exchange tubes (12). The header comprises: a metal plate (18) through which the tubes (12) pass and which has two long edges (26) for the crimping of the header (10) to a header box (16); and a plate (22) comprising a polymer material, placed above the metal plate (18) and provided with openings (42) for receiving the tubes (12).

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular for motor vehicles. More precisely, the invention relates to a heat exchanger head comprising a bundle of tubes and at least one header (also called water tank). Background technique [0002] Typically, the head receives the tubes through tube receiving ports, which are openings made in the head at regular intervals that define the tube spacing. [0003] In order to improve the heat transfer performance of the heat exchanger, the tube spacing can be reduced, which allows the head to accommodate more tubes. [0004] It is known that aluminum heads do not accommodate as many tubes as steel heads because the tube spacing cannot be reduced below a certain value. This is because the mechanical strength of the aluminum head must be sufficient to resist the pressure of the heat transfer fluid during the normal use of the heat exchanger, so the thickness of the aluminum material of this hea...
