Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fan motors, in particular to a heat dissipation structure of a fan motor. Background Art
[0002] The casing of a fan motor is usually a closed structure, which makes it difficult to conduct the generated heat into the air, and the heat dissipation efficiency of a traditional fan motor is relatively low. This is because the casing of a traditional fan motor is usually small and the heat dissipation area is limited, resulting in poor heat dissipation. The heat dissipation path of a traditional fan motor is relatively fixed and it is not easy to dissipate heat. Therefore, under long-term high-load operation, heat accumulation may cause the motor to overheat. At the same time, some existing motor fans are limited by the coil temperature rise, which affects the motor efficiency. Utility Model Content
