this paper relates to a built-in cooling fan for computer displays, especially the cooling fan structure of a computer display with better cooling effect.

it is known that the shell of a computer display is provided with reticular heat dissipation holes, which can assist heat dissipation by air convection.the heat dissipation holes are arranged at the top side or the back side of the shell, etc. Since the interior of the computer display housing is provided with heating elements such as a cold cathode ray tube (CRT) electron gun, only scattered the convection of air in the hot holes to assist in heat dissipation is not enough, so the shell and interior of the computer display are often kept in a high temperature state, which is easy to damage components without high temperature resistance in the computer display, thus reducing the service life and seriously affecting the operation stability.

the purpose of this paper is to overcome the shortcomings of the existing structure, such as poor heat dissipation effect, affecting the service life of computer displays, and further provide a built-in heat dissipation fan for computer displays.

the purpose of this article is realized as follows:

the purpose of this article can be further realized by the following technical measures:

for the aforementioned fan, the periphery of the fan seat is provided with a plurality of lugs, while the periphery of the assembly hole is provided with a plurality of grooves, the fan seat of the fan is fitted in the assembly hole, and the lugs of the fan seat are fitted in the grooves on the periphery of the assembly hole, and the fan seat is fixed to the assembly hole.

for the aforementioned fans, the assembly holes can be arranged on the rear side or above both sides of the casing.

the aforementioned fan can be ultrasonically joined, screwed or embedded in the assembly hole. The advantages of this article are that since the computer display housing is provided with an assembly hole which is provided with a heat dissipation fan, when the heat dissipation fan is driven to operate, the computer display the internal high temperature can be discharged, reducing the temperature of the shell and the inside of the computer display, avoiding high temperature damage to components without high temperature resistance in the computer display, thus prolonging the service life of the computer display and improving the operation stability.
