DETAILED DESCRIPTION

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The embodiments of this utility model will be described below based on its overall structure.

[0024] In this embodiment, please refer to Figure 1 - Figure 7 As shown, an auxiliary heat dissipation device for an industrial control computer chassis includes an industrial control computer chassis 1. A top cover 101 is screwed onto the top of the chassis 1. A square through-hole 1011 is formed in the center of the top cover 101, and a heat dissipation mechanism is installed within the square through-hole 1011. The heat dissipation mechanism consists of a mounting block 2, a cooling fan 3, a quick-release assembly 4, and a dust filter 5. A circular hole 201 is formed in the center of the mounting block 2, and a mounting bracket 2011 is fixed within the circular hole 201. The cooling fan 3 is installed on the lower surface of the mounting bracket 2011. A rubber shock-absorbing pad (2mm thick) is provided at the connection between the cooling fan 3 and the mounting bracket 2011, which can effectively... The dust filter 5 absorbs the vibration generated by the fan operation, reduces noise, and prevents the vibration from being transmitted to other parts of the chassis, causing loosening or damage. The dust filter 5 is placed above the mounting bracket 2011. Grooves 202 are provided on both sides of the mounting block 2. The quick-release component 4 is located on the mounting block 2. Fixing blocks 102 are welded to both sides of the square through hole 1011 on the lower surface of the top cover 101. Several insertion holes 1021 are provided on the side of the two fixing blocks 102 facing the mounting block 2. The actuator of the quick-release component 4 matches the insertion holes 1021 for quick installation of the heat dissipation mechanism and at the same time presses and fixes the dust filter 5.

[0025] L-shaped guide plates 301 are symmetrically fixed on the lower surface of the mounting block 2. Both L-shaped guide plates 301 have perforated plates 302 installed on their surfaces. The width of both L-shaped guide plates 301 is the same as the width of the mounting block 2, and both L-shaped guide plates 301 are located on both sides below the cooling fan 3.

[0026] When the industrial control chassis 1 is in operation, the cooling fan 3 is powered on and generates downward airflow. The airflow enters the interior of the industrial control chassis 1. At this time, the L-shaped guide plates 301 on both sides form two longitudinal airflow channels, which guide part of the airflow generated by the cooling fan 3 to other heat-generating areas inside the chassis. The perforated plate 302 allows part of the airflow to diffuse radially to both sides through the holes, avoiding local turbulence caused by concentrated airflow. At the same time, it ensures that the temperature of each area inside the chassis is balanced. Finally, after the hot air completes heat exchange inside the chassis, it is discharged through the ventilation holes on the side of the chassis, forming a complete heat dissipation cycle.

[0027] When regular maintenance is required, the worker only needs to pull the horizontal plate 401 in the quick-release assembly 4 upwards (the upper surface is provided with a pull handle), and through the linkage structure of the movable plate 402 and the linear push plate 405, the L-shaped plate 406 is controlled to move into the recess 202, so that the plug-in rod 4061 is separated from the plug-in hole 1021, and the entire heat dissipation mechanism can be taken out from the square through hole 1011. At the same time, the upward moving horizontal plate 401 will also cancel the pressing and holding of the dust screen 5, and then the dust screen 5 can be easily taken off for cleaning or replacement. After cleaning is completed, the installation steps are followed to reassemble to restore use;

[0028] Therefore, through the linkage design of the horizontal plate and the movable plate, the original operation requiring two hands is simplified to a single-step pressing action, further reducing the disassembly and assembly time, and greatly improving the convenience of later maintenance. At the same time of fixing the heat dissipation mechanism, the horizontal plate forms a pressing and holding fixation on the dust screen, so that the disassembly and assembly of the dust screen and the maintenance of the heat dissipation mechanism are completed synchronously, solving the problem of separate operation for cleaning the dust screen in the original technology, and further simplifying the maintenance process.

The upper surface of the mounting block 2 is provided with a communicating movable slot 2022 at the moving groove 2021. The two movable plates 402 pass through the movable slot 2022 and are movably connected. The two movable plates 402 are provided with a strip-shaped through groove 4021. The two movable slots 2022 are fixed with horizontal rods 203. The strip-shaped through groove 4021 is sleeved on the horizontal rod 203.
