Cooling Fan in our lives to provide a lot of convenience, but in the choice of fans we should be careful, cooling fan almost all industries are involved, so in considering the use of the environment and cooling effect, etc. , cooling fan manufacturers will develop different types of fans, parameters, functions, here we look at the application of cooling fan manufacturers standard. 1, cooling fan used in various places, need to be moisture-proof or waterproof, dust-proof, anti-corrosion performance 2, need good heat dissipation performance, need high air volume, high wind pressure cooling Fan 3, speed, fan rotation speed, fan rotation speed, this is an important parameter, high speed air volume, so there are points high, medium, low speed. 4. Air Volume is a measure of a cooling fan capacity of the quantitative indicators 5, the direct impact of air pressure ventilation or cooling effect. 6, noise is a very important parameter, for different environmental requirements 7, bearing system is directly linked to the life of the cooling fan, there are hydraulic bearings, oil bearing, double ball bearing. Shenzhen Dongxingyue Technology Co. , Ltd. is a professional manufacturer specializing in the production and distribution of heat fans. The company has a wide range of products, with low noise, small vibration, large air volume, high efficiency, long service life, etc. , we are able to customize the cooling fans according to the strict requirements of our customers.
