For achieving the above object, the technological scheme that the utility model is taked is: include air chamber and main leaf, air chamber is set to connect with main leaf by welding manner, the outer side wall of the end that air chamber is connected with main leaf is provided with the flange that extends along the air chamber periphery, main leaf is set to U groove structure on axial direction, the end face of the U groove of main leaf is set to connect with the flange contact-type of air chamber.

The end face of the U groove of main leaf is contacted with the flange of air chamber, make the groove that has formed welding between the two, use welding equipment just can link together main leaf and air chamber by welding manner, owing to designed the flange of air chamber, make the point of attachment of air chamber and main leaf form welding track line with groove, improve the welding quality of air chamber and main leaf, therefore improved the sealability of automobile intercooler.

The utility model has designed, and the cross section of the flange of air chamber is set to rectangle, trapezoidal or circular arc.

The utility model has designed, and the width D 1 between two flanges transversely of air chamber is set to equate with the width D 2 of the U groove of main leaf.

The utility model has designed, and is respectively arranged with the tongue that protrudes the U groove at the two ends of main leaf, and tongue is set to tilt to the U groove.

The utility model has designed, and the length L of tongue is set to 25-45mm.

Five, embodiment

Accompanying drawing is first embodiment of the present utility model, specify present embodiment in conjunction with the accompanying drawings, include air chamber 1 and main leaf 2, air chamber 1 is set to connect with main leaf 2 by welding manner, the outer side wall of the end that air chamber 1 is connected with main leaf 2 is provided with the flange 11 that extends along air chamber 1 periphery, main leaf 2 is set to U groove structure on axial direction, be respectively arranged with the tongue 21 that protrudes the U groove at the two ends of main leaf 2, tongue 21 is set to tilt to the U groove, the length L of tongue 21 is set to 25mm, the end face of the U groove of main leaf 2 is set to connect with flange 11 contact-types of air chamber 1, and the width D 1 between two flanges 11 transversely of air chamber 1 is set to equate with the width D 2 of the U groove of main leaf 2.

In the present embodiment, the cross section of the flange 11 of air chamber 1 is set to rectangle, trapezoidal, circular arc.

The end face of the U groove of main leaf 2 contacted with the flange 11 of air chamber 1, make the groove that has formed welding between the two, use welding equipment just can link together main leaf 2 and air chamber 1 by welding manner.

Among second embodiment of the present utility model, the length L of tongue 21 is set to 45mm.

Among the 3rd embodiment of the present utility model, the length L of tongue 21 is set to 35mm.

There is the development and production history of carrying out the automobile intercooler in 10 years in my company, and in the production of automobile intercooler, the leak-down rate of automobile intercooler is higher, the leak-down rate of reduction automobile intercooler is consistent to be the technical issues that need to address in the same industry, because the leak-down rate of automobile intercooler is higher, make the repair rate of product also higher, increased manufacture cost, I carry out scientific research at company organization's person skilled, by using different welding methods, though can reduce leak-down rate, need to change welding equipment, can not promote; By design of the present utility model, find to have formed a railway line that is applicable to various welding between air chamber 1 and the main leaf 2, improved the welding quality between air chamber 1 and the main leaf 2; During afterwards product quality inspection, find that heat dissipating pipe 3 and the leak-down rate of main leaf 2 by the joint of welding manner have also reduced significantly, improved by the parallelism between the main leaf 2 of the analysis to measure discovery left and right sides, by the quality of product test, the leak-down rate of returning existing automobile intercooler is reduced in 0.5%.

Air chamber of the present utility model bottom is provided with the clip of protrusion, be limited in grooved main leaf top, the outer surface of main leaf and the outer surface of clip are in the same plane, form angle by the fillet of clip bottom plane and the top of grooved main leaf, and the trajectory of welding both was provided in welding, can increase welding reliability again, after the welding, main leaf and air chamber are finished and are become one, and face of weld forms perfect whole circular arc line, not only attractive in appearance but also smooth, and reduced leak-down rate.
