Round tube air chamber car intercooler

Abstract

The invention discloses a circular tube air chamber automobile intercooler. The circular tube air chamber automobile intercooler adopts aluminum circular tubes to make an air chamber which replaces a cast air chamber and a main piece in an original intercooler. One end of a circular tube air chamber (2) is bent to form a required angle; the bent part serves as an air inlet and outlet section; a straight line part serves as an air chamber section; a mounting hole for a cooling tube (3) and a mounting hole for a side plate (1) are machined in regulated positions on the air chamber section, so that the air chamber section also has the function of a main piece; cooling tubes (3) and side plates (1) are installed in prefabricated holes of left and right circular tube air chambers (2); heat dissipation straps are installed between the cooling tubes (3) and between the cooling tubes (3) and the side plates (1); the other end of the circular tube air chamber (2) is plugged through a blocking cap (6); a guide plate (7) is installed at the tail of the circular tube air chambers (2). An assembled intercooler is fixed through a special clamp, brazing is accomplished in a nitrogen protection brazing furnace, and the clamp is removed after the intercooler is discharged from the furnace, so that the manufacture of an intercooler assembly is accomplished.

Description

technical field [0001] The invention relates to an intercooler, which is a core component in an air intake intercooling system of an automobile engine. Background technique [0002] At present, the known automobile engine intercooler is made up of parts such as air chamber, cooling pipe, heat dissipation belt, main sheet, turbulent flow sheet and side plate. Wherein, the air chamber is cast by aluminum material. The main plate and side plates are all stamped and processed by aluminum plates, and the cooling pipes, heat dissipation strips and turbulent flow plates are manufactured by special equipment. In the degassing chamber, other parts are assembled into core parts according to the prescribed order, and are welded by nitrogen protection brazing process to form a core part with firm connections between parts. The main part on the core is welded to the air chamber by argon arc welding Together, it becomes a car engine intercooler. [0003] According to the flow form of p...

AI Technical Summary

Problems solved by technology

[0006] The air chamber is casted by the air pipe and the chamber body as a whole. Due to the limitation of comprehensive conditions, the inner arc radius of the connection between the air pipe and the chamber body is relatively small, which leads to the increase of the resistance of the pressurized air flow here and the decrease of the flow pressure, so that Reduced operating efficiency of the intercooler

[0007] The connection between the gas chamber and the core is welded by argon arc welding, which has low production efficiency and high cost

[0008] The main piece is stamped sequentially by multiple sets of molds, the mold manufacturing cost is high and the cycle is long
