Hub structure

Abstract

A hub structure includes an annular body and a flow guide unit. The annular body has a top end and a receiving space. The flow guide unit is disposed at the top end of the annular body. At least one raised section is formed on one face of the flow guide unit opposite to the receiving space. A motor set is disposed in the receiving space. When the motor set operates, the annular body and the flow guide unit are driven to rotate around the axis of a shaft rod. At this time, airflow is conducted through the raised section into the receiving space to dissipate the heat generated by the motor set. Accordingly, the temperature of the motor set can be effectively lowered to prolong the lifetime of the motor set.

AI Technical Summary

Benefits of technology

The present invention is an improved hub structure with a flow guide unit that can guide more airflow into the hub structure to enhance heat dissipation. The hub structure includes an annular body and a flow guide unit with a raised section on a face opposite to the receiving space, where a motor set is located. The flow guide unit is disposed at the top end of the annular body and rotates with the motor set to dissipate the heat generated by the motor set and lower its temperature, prolonging its lifetime. The hub structure has the advantage of effectively conducting airflow and enhancing heat dissipation for the motor set.

Problems solved by technology

Otherwise, the performances of the electronic component will be greatly affected to slow down the processing speed of the electronic component.

In some more serious cases, the electronic component may even burn out due to overheating.

Therefore, heat dissipation has become a critical issue for all kinds of electronic components.

It is an important issue how to dissipate the heat generated by the coils and the electronic components.

This will shorten the lifetime of the cooling fan.

However, the airflow cannot be effectively conducted through the through holes 121 to the motor set 13.

Therefore, the heat dissipation effect for the motor set 13 is poor.

As a result, the motor set 13 is likely to damage due to overheating.

This will shorten the lifetime of the cooling fan.

Therefore, the conventional hub structure has the following defects:1. The airflow cannot be effectively conducted.2. The heat dissipation effect for the motor set is poor.3. The motor set is likely to damage due to overheating to shorten the lifetime of the cooling fan.
