Description

Technical Field

[0001] The utility model belongs to the technical field of industrial integrated machines, and in particular relates to a heat dissipation fan assembly. Background Art

[0002] With the continuous development and progress of the economy and society, the level of industrialization is also constantly improving. For the traditional manufacturing industry, with the continuous increase in labor costs and the continuous increase in production capacity requirements, in order to meet the needs of automated production, for various automated equipment, corresponding controllers (industrial all-in-one machines) are indispensable.

[0003] As all-in-one computers are now widely pursuing the advantage of compact size, all hardware facilities are usually concentrated in the all-in-one computer casing. Therefore, the heat generated by the all-in-one computer is also relatively concentrated, and the internal temperature of the all-in-one computer needs to be cooled.

[0004] For example, the Chinese patent of the prior art CN218217978U discloses an overall structure of an industrial all-in-one machine, including an industrial all-in-one machine body, the industrial all-in-one machine body includes a display housing, a mounting cavity for mounting electrical components is arranged in the display housing, an inspection port is arranged on the display housing, an inspection panel is arranged at the inspection port, a cooling component is arranged at the inspection panel, a plurality of heat dissipation ports are arranged on the display housing, a connecting block is arranged at the heat dissipation port, and an anti-collision layer is arranged on one side of the connecting block.

[0005] However, the above-mentioned prior art has certain technical problems. Its structural design is particularly simple, and it mainly relies on a single cooling fan for cooling. The cooling method is rough, and since the diameter of the heat dissipation holes on its maintenance plate is small, the heat inside the all-in-one machine cannot be quickly volatilized, and the heat dissipation efficiency is low. Utility Model Content

[0006] In view of this, an object of the utility model is to provide a heat dissipation fan assembly with simple structure, convenient installation and high heat dissipation efficiency.

[0007] To achieve the above purpose, the utility model adopts the following contents:

The fins are all made of metal, and there is a heat dissipation space between the fins. The heat inside the all-in-one machine is absorbed by these fins, and then the airflow generated by the fan continuously blows the fins to quickly take away the heat on the fins.

The fan mounting frame, the middle plate, and the radiator bracket are integrally connected by screws, which facilitates the disassembly and assembly of the fan mounting frame and the radiator bracket.

[0015] Furthermore, the vertical screws also pass through the rubber buffer support from top to bottom, thereby saving the installation space between the fan installation frame and the middle plate and maximizing the use of space.

[0016] According to a heat dissipation fan assembly provided by the utility model, four brackets with a rotationally symmetrical structure are arranged at the bottom of the fan mounting frame, and a mounting plate is connected between the four brackets.
