Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, shall fall within the scope of protection of the present invention.

The structure of an automobile intercooler air chamber is shown in figure 2, and comprises a cover plate structure 1 and an air chamber base body 2, wherein two ends of the cover plate structure 1 are fixedly connected with the air chamber base body 2 respectively.

The cover plate structure 1 in this embodiment includes a gas chamber cover plate 101 and an end cover 102, the gas chamber cover plate 101 is disposed at the front end of the gas chamber base body 2, and two ends of the end cover 102 are respectively fixedly connected to the gas chamber base body 2. The gas chamber cover plate 101 and the end cover 102 are designed in an integrated structure, a flange 103 is arranged at the joint of the gas chamber cover plate 101 and the end cover 102, and the embodiment adopts an n-shaped flange. Through setting up turn-ups 103, simplified the assembly process greatly, the assembly part is also difficult for droing to guarantee that the difficult leakage that leaks behind air chamber base member 2 and the welding of air chamber apron 101, increase the qualification rate of brazing.

The gas chamber base body 2 is provided with a buckling structure 3 for positioning and fixing the end cover 102, the end cover 102 is fixed on the gas chamber base body 2 through the buckling structure 3, and then the gas chamber cover plate 101 is connected with the gas chamber base body 2 in a welding mode through brazing.

The car intercooler is present common full aluminium intercooler in this embodiment.

The production practice proves that:

1. the assembling and connecting surface of the end cover and the air chamber cover plate is changed into an integral flanging structure, the one-time brazing qualification rate is increased from 95.8 percent to 99.7 percent, the product quality is greatly improved, and the cost is reduced;

2. after the air chamber cover plate is changed into an integral structure, the pressure pulse test is closed once.

The economic benefits before and after improvement are compared as follows:

the yield is assumed to be 20000 tables per year, and each table is 200 yuan.

Before the improvement: the primary brazing qualification rate is 89%, and the production rate is 17-20 pieces/1 hour/person;

after the improvement: the primary brazing qualification rate is 98.2 percent, and the production rate is 30 to 35 pieces/1 hour/person.

While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention.
