this article relates to a computer cooling fan .

computer internal electronic components usually generate heat when working, causing the temperature of components to rise, which will affect the normal operation of components. Therefore, heat dissipation devices must be installed to ensure the normal operation of components at appropriate temperatures. For

the technical problem to be solved in this paper is to provide an adjustable heat sink, which can be applied to different types of computers.

the technical scheme adopted in this paper to solve the technical problems is as follows:a computer heat dissipation fan comprises a shell and radiating fins, wherein the radiating fins are packaged in a shell 1, and the shell is fixed on a computer case; The shell is provided with a waist-shaped hole through which radiating fins pass by bolts 4 is fixed in the shell 1; The shell is provided with a waist-shaped hole on the end face corresponding to the chassis, and the heat dissipation device is fixed on the chassis through the waist-shaped hole by bolts. In the preferred scheme herein, a plurality of groups of waist-shaped holes are arranged at the same position on the shell.

the beneficial effects of this paper are:it provides a new structure of heat sink.the design of waist-shaped hole on the shell can adjust the distance between heat sink and chassis.the design of waist-shaped hole on the shell can adjust the position of heat sink relative to chassis. In other words, according to yuan device position, adjust the heat sink. Therefore, this heat sink is suitable for different types of computers.brief description of the drawings fig.1 is a front view of the heat sink described herein; Fig.2 is a top view of the heat sink described herein.

as shown in fig.2, the end face of the shell corresponding to the chassis 3 is provided with a waist-shaped hole through which the heat dissipation device is fixed to the chassis by bolts. Adjust the position of the bolt in the waist-shaped hole to adjust the position of the heat sink relative to the chassis. In other words, according to the meta-device piece position, adjust the radiator.
