DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following further describes the present application in detail Figures 1 - 3 with reference to the accompanying drawings.

[0019] An embodiment of the present application discloses a heat dissipation device for a sheet metal cabinet. Refer to Figures 1 - 2, including a heat dissipation housing 1. A working chamber 8 is provided inside the heat dissipation housing 1. Fixing ears 6 are welded at the outer wall corners of the heat dissipation housing 1. The heat dissipation housing 1 is pre-installed outside the ventilation opening of the sheet metal cabinet through the fixing ears 6. A heat sink 10 is installed inside the heat dissipation housing 1. The heat sinks 10 are distributed in an axial array on the outer wall of the water-cooling pipe 9, forming an effective air flow channel to accelerate the heat circulation. A water-cooling pipe 9 is provided on one side of the heat sink 10. The water-cooling pipe 9 is spirally arranged and can be connected to an external coolant pump to facilitate the transportation of coolant for water cooling and improve the heat dissipation efficiency.

[0020] Combined Figure 3 As shown, two through openings 2 are provided on the outer wall of the heat dissipation housing 1. A ventilation net 7 is detachably provided in the through openings 2. Slide rails 11 are symmetrically provided on the outer wall of the ventilation net 7. A fan assembly is provided on the slide rails 11. The fan assembly includes a bidirectional lead screw 14 provided in the middle of the heat dissipation housing 1, and a fan 5 installed outside the slide rails 11. A central track 3 is installed between the two through openings 2. The central track 3 is fixed to the inner wall of the through opening 2, and a double-headed motor 13 is installed at the center inside the central track 3. The output end of the double-headed motor 13 is in transmission connection with the bidirectional lead screw 14;

[0021] A sliding block 15 that is adapted is slidably connected to the bidirectional lead screw 14. One end of the sliding block 15 extends outside the central track 3 and symmetrically welded connection arms 16 are provided. The end of the connection arm 16 away from the sliding block 15 is connected to a heat dissipation cover 4 by screws. Therefore, as the sliding block 15 works, the sliding block 15 can be pushed to move synchronously through the connection arm 16, facilitating the mutual approach or separation of the fan assemblies on both sides to achieve heat dissipation in different areas.

[0022] In addition, sliders 12 are fixed at both ends of the inner wall of the heat dissipation cover 4. The sliders 12 are slidably adapted to the slide rails 11. The slide rails 11 are screwed to the outer wall of the heat dissipation housing 1. As the heat dissipation cover 4 moves, the sliders 12 will cooperate to slide and support on the slide rails 11 to ensure the stability between the structures.

[0023] The implementation principle of a heat dissipation device for a sheet metal cabinet in an embodiment of the present application is as follows: During use, the fixing ears 6 are fixed outside the ventilation opening of the sheet metal cabinet through bolts, thereby installing the heat dissipation housing 1. The water-cooling pipe 9 is pre-connected to a cooling pump and is spirally arranged to fit the outer wall of the equipment inside the cabinet, achieving a good water-cooling heat dissipation effect. The heat sinks 10 are distributed in an axial array on the outer wall of the water-cooling pipe 9, forming an effective air flow channel, which can conduct and transfer heat well. At this time, the heat is discharged outward through the ventilation net 7. At the same time, the double-headed motor 13 can be driven to drive the bidirectional lead screw 14 to work, so that the sliding block 15 can push the two groups of heat dissipation covers 4 to move relatively or in opposite directions on the slide rails 11 through the connection arms 16. Since the fan 5 is set to be flexibly movable, it can evenly dissipate heat from the equipment inside the cabinet, avoid the phenomenon of over-high temperature in local areas, and ensure the stable operation of the equipment.
