The cooling fan manufacturers found that: waterproof cooling fan with a higher degree of protection of the cooling fan. In the application of the environment (water / salt mist / oil / corrosive gases) heat conduction and thermal radiation can not meet the cooling needs, the demand for cooling fan convection cooling and must ensure long-term effective cooling requirements, cooling fan itself to protect the necessary products to enhance the product.
To solve the problem of cooling the cooling fan: the edge of the paint seal with a special glue on the whole motor to stop all-round seal, etc., different fan R & D team from time to time research and development, exploration, experiment, manufacturing waterproof cooling fan.
The role of waterproof cooling fan:
1. Insulation liquid coating soaked after the entire motor drying seal.
2. Insulation liquid coating after immersion vacuum vacuum coating insulation effect and characteristics are different
3. Simple method, the process is simple: sealed coating thickness, easy to have bubbles, pressure tolerance, assembly and operation easy to destroy the seal.
