Background

In the information explosion age, electronic products have been in inseparable relationship with daily life. With the continuous evolution of science and technology, various electronic products have been developed. As for the development and application of personal computers, desktop personal computers (desktop PCs) were developed. However, desktop computers have a large volume and are inconvenient to carry, so portable electronic devices such as notebook computers (notebook PCs) and Tablet PCs (Tablet PCs) have been developed. With the trend of light weight and thin and high performance of portable electronic devices, the heat generated by the portable electronic devices is increased, and therefore, the heat generated by the heating element must be effectively discharged to the outside by the heat dissipation device to ensure the normal operation of the portable electronic devices. The fan is one of the most commonly used heat dissipation devices, and blows or draws away hot air near the heating element, so that heat generated by the heating element can be taken away by the air near the heating element to achieve a heat dissipation effect.

If the fan needs to have additional light-emitting effect and damping effect, the fan case is usually designed to be combined so as to install the light bar and the damping pad in the fan case. However, the current combined fan case still has the problem of too complicated assembling steps. Therefore, one of the problems that should be solved by the research and development staff is how to improve the problem that the assembly steps of the fan case are too complicated.
