Description

Technical Field

[0001] The utility model relates to the technology of fan field, in particular to a fan with a heat dissipation structure. Background Art

[0002] Electric fan is also called fan or blower. It is a household appliance that uses an electric motor to drive the blades to rotate to accelerate the circulation of air. It is mainly used for cooling and circulating air. It is widely used in homes, classrooms, offices, shops, hospitals, hotels and other places. It is also widely used in the industrial field.

[0003] Most fans use motors to drive the blades to rotate. When power is turned on, current passes through the coil, and the coil wire has resistance, so it will inevitably generate heat and dissipate heat outward. Therefore, a large amount of heat will be generated during the operation. However, existing fans do not have a specific heat dissipation mechanism for the motor, resulting in a large amount of heat accumulation in the motor part during operation. After long-term use, the temperature will be too high, which will not only affect the working state of the fan, but also damage the internal structure of the motor, thereby affecting the service life of the fan. Therefore, it is necessary to further improve the existing fan structure. Utility Model Content

[0008] As a preferred solution, the motor is fixedly mounted on the front side of the mounting slot by means of mounting bolts, and the output end of the motor extends forwardly out of the mounting slot.
