Automobile all-aluminum intercooler

Abstract

The invention relates to an automobile all-aluminum intercooler which comprises a core and air chambers connected to the two ends of the core. The core comprises a main sheet and side boards connectedwith the main sheet. The main sheet comprises a main sheet body and a turned edge structure arranged on the periphery of the main sheet body, and the turned edge structure is in fixed and attached connection with assembly connecting faces of the air chambers. Compared with the prior art, the automobile all-aluminum intercooler has the advantages of being high in product quality, high in percent of pass, simple in assembly process, capable of saving manpower and material resources, beautiful in appearance, high in economic benefit and the like.

Description

technical field [0001] The invention relates to the field of automobile intercooler manufacture, in particular to an automobile all-aluminum intercooler. Background technique [0002] After the engine adopts turbocharging technology, it will have greater power than ordinary engines. One of the reasons is that its ventilation efficiency is higher than the natural intake of ordinary engines. When the air enters the turbocharger, its temperature will increase significantly, and its density will decrease accordingly, and the intercooler just plays the role of cooling the air. The high-temperature air is cooled by the intercooler and then enters the engine. If there is no intercooler and the supercharged high-temperature air directly enters the engine, the engine will knock or even be damaged and stalled due to the high air temperature.

AI Technical Summary

Problems solved by technology

If there is no intercooler and the supercharged high-temperature air directly enters the engine, the engine will knock or even be damaged due to the high air temperature.

[0003] Existing intercoolers generally include a main piece, a side plate and an air chamber, and the main piece includes a main piece body and connecting parts on both sides, such as figure 2 and image 3 Shown; There are gaps on both sides of the air chamber that match the connecting parts, such as Figure 10 As shown, the main piece and the air chamber are matched and connected. This connection method makes the connection surface or connection line between the main piece and the air chamber more complicated. When the two parts are connected by welding, the success rate is not high, and the product qualification rate is not satisfactory. requirements; and, when the side plate is assembled with the main piece, since there are no obvious positioning parts at both ends of the side plate, such as Image 6 and Figure 7 As shown, the existing intercooler has the following problems:

[0004] (1) The qualification rate of the first-time brazing of the intercooler is not high; the qualification rate is between 94% and 96.2%;

[0005] (2) The assembly of the intercooler is inconvenient to install, labor-intensive, high in cost, and the assembly quality cannot meet the brazing requirements;

[0006] (3) The side plate of the intercooler is not easy to locate, and it is easy to have inconsistent lengths at both ends, which affects the appearance

In this mechanism, due to the side undercut structure connection between the main piece and the air chamber, the manufacturing process of this connection method is relatively complicated, which affects the assembly efficiency
