Abstract

The invention belongs to the technical field of metal materials, and particularly relates to a lower water chamber. The lower water chamber is made of aluminum alloy, and the aluminum alloy is composed of the following raw materials of, by mass, 0.5-2.5% of cage type polysilsesquioxane, 0.02-0.1% of Sr, 0.15-0.25% of Zr, 0.04-0.1% of Mn, 0.07-0.14% of Zn and the balance Al and impurities. The lower water chamber is manufactured by adopting the following process steps of carrying out smelting, carrying out airflow stirring, carrying out curing and forming and obtaining a finished product, and finally the obtained product has relatively good strength, hardness, elongation and corrosion resistance, and is suitable for a complex application environment.

Description

technical field [0001] The invention relates to a 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 effect played by the lower water chamber in the radiator still has a relatively large effect. However, the shape of the water chamber has been determined during the preparation, and it is impossible to optimize the shape to pr...
