AI Technical Summary
In existing high-speed turbine fans, the stator and coils are susceptible to water corrosion, leading to circuit failures, and poor heat dissipation can damage the controller, especially in aquatic environments.
The system uses a convex ring and a screw ring in combination with a first thermally conductive silicone and a second thermally conductive silicone to conduct the heat from the controller to the heat sink through thermal conduction. The heat is then blown away by the airflow from the main fan body to prevent the coil and controller from getting damp.
It effectively prevents the stator coils and controller from getting damp, improves heat dissipation performance, and avoids circuit failures and controller damage.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of fan heat dissipation technology, specifically to a waterproof and heat dissipation device for a fan and controller. Background Technology
[0002] In many high-speed turbine fans, the stator and coils are located in the middle, using the fan's own airflow to dissipate heat from the coils on the stator. However, with the coils in the middle, they are easily affected by ambient water flowing into them, causing circuit faults and preventing the entire fan from turning. Neither the stator nor the controller has a waterproof design, making it particularly vulnerable to damage, especially in wet environments. Dust on the controller can also cause damage. If the fan is completely sealed without proper heat dissipation, the heat inside the stator coils will rise and burn them out. The same applies to the controller; if heat dissipation is inadequate, the temperature will rise and burn out the controller as well. Utility Model Content
