Often because of space issues, we need to use thinner cooling fans. Doing this choice will solve the space problem, but will it bring other problems? There are mainly the following aspects to pay attention to.

    1. Cost, it is very possible that the ultra-thin cooling fan is more expensive than the thicker one, because the production is more difficult and easy.

    2. Air volume, air pressure, thinner cooling fan, the power is smaller than thicker, the air volume will be smaller, barely make it the same size, the cost may be higher.

    When choosing the thickness, of course, choose a medium-thickness cooling fan, which has a higher cost and a relatively more stable structure. For example, 10MM and 25MM thicknesses are very common.

    For some special occasions, where the cooling fan is installed, the temperature is very high. It is hoped that the cooling fan can withstand high temperature and heat dissipation. Then, how much temperature can the cooling fan withstand?

    Generally, the working temperature of the conventional cooling fan is -10 degrees -70 degrees. If the temperature is higher than 80 degrees in a special environment, a special design is required. A high temperature resistant IC is used to reduce the current of the motor to make the motor's own The temperature drops to the bottom. In addition, enameled wires, plastic materials and wires should also be high temperature resistant, and the temperature should not exceed 100 degrees.

    When the temperature is too high, whether it is a heat-resistant cooling fan or an ordinary cooling fan, the longevity will be greatly reduced. Therefore, when designing the product, the ambient temperature should be controlled below 70 degrees.
