Abstract

The invention belongs to the technical field of metal materials, and specifically relates to an upper water chamber. The upper water chamber is made of aluminum alloy, and the aluminum alloy is composed of the following raw materials in mass percentage: cage polysilsesquioxane: 0.5-2.5 %, Tl: 0.03-0.09%, Zr: 0.2-0.3%, Mn: 0.08-0.12%, and the balance is Al and impurities. It is prepared through smelting, air flow stirring, solidification molding, and finished products. By adjusting the ratio of raw materials and process changes, the final product has good strength, hardness, elongation and corrosion resistance, and is suitable for complex Use the environment.

Description

technical field [0001] The invention relates to an upper water chamber, which belongs to the field of metal materials. Background technique [0002] The automobile water chamber is an important part of the automobile radiator. The automobile water chamber is generally arranged on the upper and lower parts of the radiator. Its function is to buffer the cooling water flowing into the radiator core and re- Delivered to the engine to ensure the cooling effect of the engine. [0003] Car water chambers can generally be simply divided into upper and lower water chambers, both of which have a single function. They are mainly used to store cooling water and assist in heat dissipation, but they are indispensable. [0004] It can be seen that the transition assisting function played by the upper water chamber in the radiator still has a relatively large effect. However, the shape of the upper water chamber has been determined during the preparation, and it is impossible to optimize ...
