What are the types of motors for cooling fans
Aug 22 , 2024
1. Brushless DC Motor (BLDC) Advantages: The brushless design reduces energy loss and improves overall efficiency. Because there is no brush, the brushless motor has less wear and longer life. Smooth operation and low noise for applications requiring a quiet environment. Disadvantage：High cost, the manufacturing process is complex, and the cost is higher than that of brushed motors. Complex contro...

Is the cooling fan life test related to humidity? -- Chungfo in-depth discussion of the influence of humidity on fan life
Nov 18 , 2024
During the use of the cooling fan, the influence of humidity on the life of the fan cannot be ignored. Especially in industrial and household appliances, such as air conditioning cross-flow fans, cross-flow cooling fans and metal cross flow fans, humidity will not only affect the efficiency of heat dissipation, but also may adversely affect the internal structure of the fan. How does humidity affe...
