The technical requirements for high-temperature resistant fans are as follows:
1. Materials should be resistant to high temperatures: The working environment of high-temperature fans is high, and materials that can withstand high temperatures need to be selected, such as high-temperature alloy materials such as 316L, 321, Hastelloy, etc.
2. Mechanical design should be reasonable: Under high temperature conditions, the heat dissipation capacity of the fan impeller and bearings decreases. When designing, factors such as strength and thermal expansion should be considered to ensure the normal operation of the impeller and bearings.
3. The heat dissipation system should be complete: under high temperatures, the heat dissipation capacity of the impeller and bearings decreases, and special heat dissipation systems need to be designed to ensure the normal operation of the fan. Such as aluminum alloy heat sink, high-temperature ceramic heat sink, etc.
4. High precision requirements: At high temperatures, there may be friction between the impeller and the impeller, as well as between the impeller and the casing. Therefore, high machining accuracy is required in the impeller design to ensure smooth operation of the fan and avoid excessive heat generation.
5. High insulation requirements: The insulation requirements for high-temperature resistant fans are very high, and the insulation materials used need to be able to withstand high temperature environments, such as graphite fiber, asbestos, and other materials.
6. High reliability: The operation reliability of fans in high-temperature environments is particularly high, requiring the use of precision machined and high-quality components to ensure that the fans can operate stably for a long time.
