Waterproof cooling fan
Home - Service - Waterproof cooling fan
Shenzhen Henggang Special Electromechanical Co., Ltd. after 6 months combined with the domestic and foreign cooling fan waterproof technology, has successfully developed an IP68 waterproof cooling fan that can be completely placed in water and has high-grade waterproof and dustproof effects: pouring glue Waterproof technology.
The produced 5V, 12V waterproof fans, 24V, 48V waterproof fans of various voltages can be completely placed in the water to work, specifically with high-level waterproof and dustproof effects. This is specially designed to solve the special heavy water vapor, even the fan will enter the water Specially developed and produced in harsh environments.
12V waterproof fan, 24V waterproof fan is the unified name of fan products with higher protection grade (IP68). It is in a harsh environment (water/salt spray/oil pollution/corrosive gas). The heat conduction and heat radiation cannot meet the heat dissipation requirements. The fan needs strong pressure convection and the fan's own protective performance must ensure that the fan can be stable in this extreme environment for a long time. of.
Waterproof fan performance and process: the domestic first brushless motor fully enclosed potting process, the core components such as: PCBA board, motor are all sealed with imported resin, the advantages of using this kind of potting waterproof are: waterproof fan used, and water , Oil, salt and alkali, corrosive substances and the environment can be highly protected, the protection level can reach: IP55, IP68, to ensure that the waterproof fan can work reliably for a long time without failure.
1. Tree finger potting potting waterproof fan performance:
A+B resin 1. Epoxy resin adhesive. This product is a widely-used, high-performance resin adhesive. It is used for shearing traction, temperature resistance, oil resistance, corrosion resistance, water, impact resistance, toughness and high strength.
2. After the waterproof fan is encapsulated, the tree fingers have very good resistance to various substances, so that the electronic control components on the motor unit can be completely isolated from water. The same motor is produced from steel materials and comes into contact with salt water or corrosive substances. It will rust later, because of the seal protection of the tree finger, so that it will not rust for a long time.
Second, the resin potting waterproof fan compared with the traditional waterproof method:
Vacuum coating process, because the process uses a vacuum coating machine to coat a part of the motor unit with a thin film to play a waterproof role, but the actual situation is only a few days after prolonged contact with water, oil, corrosion, salt and alkali substances Or a few weeks, the film on the motor needs to fall off, so that the fan loses the waterproof protection. The resin is encapsulated in the waterproof fan. Since the resin is mixed together by the two fats of A and B, after the potting is cured, it sticks to the motor group. Integral, through the water, saline-alkali environment test, the waterproof fan of the resin potting process can work for a long time, the resin will not be damaged or fall off.
