Embodiment Construction

[0046] figure 1 A first exemplary heat exchange device 10 is shown. This basically comprises the heat exchanger 12 , the protection device 14 for the heat exchanger 12 and the attachment part 16 on the heat exchanger 12 .

[0047] Heat exchanger 12 in figure 2 and 3 shown more clearly in . The heat exchanger comprises two bundles 18 , 20 of tubes 22 designed to be passed through by the fluid to be cooled, the tubes 22 in a single bundle 18 , 20 being separated from each other by cooling fins 24 .

[0048] The first tube bundle 18 is arranged parallel to the second tube bundle 20 and is offset in the direction of the air flow F generated by the vehicle during movement. The tubes 22 of the two bundles 18 , 20 extend mainly in a common longitudinal direction Y between the first collecting plate 26 and the second collecting plate 28 . Each collecting plate 26 , 28 extends mainly in the longitudinal direction X. In this case the collecting plates 26 , 28 are parallel perpend...

Abstract

The invention relates to a heat exchange device (10) for a motor vehicle comprising a heat exchanger (12) having a first and a second collecting plate (26; 28), a First and second header tanks (30; 56) and bundles (18; 20) of tubes (22) extending between the first and second collecting plates (30; 56). Each collecting plate (30; 56) forms a groove (54; 72) between the tubes (22) of the tube bundle (18; 20) and the side end (50; 68) of the respective collecting plate (30; 56). The puncture protector (14) for the tube (22) is attached to the heat exchanger (12) using attachment means (78, 80) which rest against the first and second The interior of the grooves (54, 72) in the collecting plate (26; 28).

Description

technical field [0001] The invention relates to a heat exchange device for a motor vehicle, comprising a heat exchanger and a protection device for the heat exchanger. The invention also relates to a method of assembling such a heat exchange device. The invention relates more particularly to a heat exchange device arranged on the front of a motor vehicle. Background technique [0002] In the automotive sector, heat exchangers arranged on the front can be affected by projected debris, especially stones, which can damage the heat exchangers. Notably, these debris can pass through the tubes of the heat exchanger containing the fluid flow to be cooled by the airflow generated by the moving motor vehicle. [0003] In order to protect these heat exchangers, it is known to place protective devices in front of the heat exchangers according to the normal direction of movement of the motor vehicle, in order to absorb the impact caused by projected debris. The protection is especial...
