Description

Technical Field

[0001] The invention relates to the technical field of aluminum plating equipment, in particular to aluminum plating equipment with a waste heat recovery and utilization function. Background Art

[0002] Aluminum plating equipment is an industrial equipment used to plate aluminum film on the surface of the substrate. It is widely used in packaging, electronics, decoration and other industries. It mainly uses vacuum coating technology. Vacuum coating technology is the core technology of aluminum plating equipment. It uses heating or electric arc in a high vacuum environment to evaporate or sputter aluminum materials onto the surface of the substrate to form an aluminum film. The main function of the vacuum environment is to reduce the collision between gas molecules and aluminum atoms, ensuring that aluminum atoms can be evenly deposited on the surface of the substrate.

[0003] The existing technology has defects: before the existing aluminum plating equipment is used to aluminum-plate the film, the surface of the film will be adhered to dust, particles in the air, etc., which will affect the adhesion effect of the aluminum vapor during the aluminum plating, resulting in poor aluminum plating effect and even causing the aluminum film to fall off; the evaporation boat is a common evaporation source in vacuum coating equipment. When in use, it needs to be heated to a high temperature by a resistor. In order to maintain the high temperature required for evaporation, a large amount of electrical energy will be consumed in this process. Most of the heat generated by the evaporation boat is dissipated into the surrounding environment in the form of heat exchange with cooling water. However, this heat is not effectively utilized and is directly discharged to the outside world. This not only leads to a large waste of resources, but may also increase the problem of thermal pollution in the environment. Summary of the invention
