Abstract

The invention discloses a shot blasting process of a heat dissipation inner container. The shot blasting process includes the following steps of placing the heat dissipation inner container onto a working platform of a controllable rotating mechanism, achieving rotation of the heat dissipation inner container through the controllable rotating mechanism, and enabling the heat dissipation inner container to keep rotating at a constant speed, spraying steel beads onto the surface of the heat dissipation inner container through a shot blasting mechanism, strengthening the shot blasting impact, and enabling plastic deformation to occur to the surface of the heat dissipation inner container so that pits can be formed in the surface of the heat dissipation inner container. According to the shot blasting process of the heat dissipation inner container, anti-corrosion alloy steel beads are sprayed onto the inner surface of the inner container and the outer surface of the inner container at the high speed, the shot blasting impact is strengthened, and the pits are formed when plastic deformation occurs to part of the surface material of the inner container to form dense, thin and even concave-convex points so that the adhesive ability between a coating and the wall of the inner container can be enhanced. According to the follow-up nanometer heat absorption coating process, the coating is adhered to the wall of the inner container in a sawtooth-shaped mode through high-temperature roasting so that the coating can be more stably and firmly combined with the wall of the inner container. Meanwhile, the invention discloses a shot blasting device of the shot blasting process.
