[0002] Multiple switches are installed in a cabinet, arranged vertically. The switches generate a lot of heat during operation. The distance between switches is small, and there are many switches. This heat is difficult to dissipate quickly, causing high temperatures and potentially causing failures.

[0003] In addition, a series of electrical components such as power supplies are installed in the cabinet. The electrical components are not installed in the same location as the switch, so it is difficult to exhaust and cool the cabinet through a single-direction air duct setting. Utility Model Content

[0004] The purpose of the utility model is to provide a high-efficiency heat dissipation cabinet, which can respectively extract and cool electrical components and switches through air ducts in two wind directions, thereby improving the heat dissipation efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

Both the front door frame and the rear door frame are provided with shutters, and the rear side of the front door frame is fixedly connected to a mounting cover, and the mounting cover is provided with a boss protruding rearward, and the boss is provided with a number of ventilation holes, each ventilation hole is distributed in an array, and a fan rack is fixedly connected to the rear side of the edge of each ventilation hole, and an exhaust fan is installed on the fan rack. An air inlet space is left between the rear end of the left supporting bar and the right supporting bar and the rear door frame, and an exhaust space is left between the front end of the left supporting bar and the right supporting bar and the front door frame. The side wall of the lower cavity is provided with an air inlet.

[0007] Specifically, a front protective cover is installed on the front side of the front door frame.

[0008] Specifically, a rear protective cover is installed on the rear side of the rear door frame.

[0009] Specifically, multiple pairs of screw holes are provided on both vertical frame bars of the front door frame. The louvers provided on the front door frame are detachable louvers. Flap pieces are provided at both ends of the detachable louvers. A pair of perforations are provided on each flap piece. The flap pieces are connected to the front door frame by screws.

[0015] The ventilation gaps connect the upper cavity and the lower cavity. The electrical components are located above the right ventilation gap. When the exhaust fan installed on the fan frame rotates, a negative pressure will be generated in the exhaust space, causing the gas in the lower cavity to flow upward into the upper cavity through the ventilation gaps. When the air flow passes through the electrical components, it will带走 the heat of the electrical components, keeping the electrical components at a relatively low temperature. External gas enters the lower cavity through the air inlet, balancing the air pressure in the lower cavity.

[0017] When it is necessary to increase the exhaust air flow of the exhaust fan, multiple detachable louvers can be removed to improve the heat dissipation effect.

[0018] The cross-section of the left connecting piece is U-shaped, and the cross-section of the right connecting piece is in the shape of multiple U-shapes connected end to end, increasing the surface heat dissipation area and thus提高 the heat dissipation rate of the switches.

[0030] See Figures 1 to 5 A high-efficiency heat dissipation cabinet includes a cabinet body, a horizontal plate 11 is provided in the middle of the inner cavity of the cabinet body, and the horizontal plate 11 divides the inner cavity of the cabinet body into an upper cavity and a lower cavity. Four vertical channel steels 12 are fixed in the upper cavity, two on the left side and the other two on the right side. The two vertical channel steels 12 on the left side are both connected to a left connecting piece 13, and the two left connecting pieces 13 are connected to a plurality of left support bars 14, and the plurality of left support bars 14 are arranged in layers along the vertical direction. The two vertical channel steels 12 on the right side are both connected to a right connecting piece 15, and the two right connecting pieces 15 are connected to a plurality of right support bars 16, and the plurality of right support bars 16 are arranged in layers along the vertical direction. The left support bars 14 and the right support bars 16 on the same layer are used to jointly support the switch (not shown in the figure).

[0031] The front and rear sides of the upper cavity are both provided with openings. The front opening edge is hinged to the front door frame 21, and the rear opening edge is hinged to the rear door frame 31. Both the front door frame 21 and the rear door frame 31 are provided with shutters. Figure 4 、 Figure 5 , on the rear side of the front door frame 21, there is a fixedly connected mounting cover 22. The mounting cover 22 has a convex platform protruding backward. The convex platform has several ventilation holes (see Figure 5 ), each ventilation hole is arranged in an array, and on the rear side of the edge of each ventilation hole, there is a fixedly connected fan frame 23. The fan frame 23 is equipped with an exhaust fan (not shown in the figure).

[0032] See Figure 2 , there is an air inlet space 18 left between the rear ends of the left support strip 14 and the right support strip 16 and the rear door frame 31, and there is an air exhaust space 17 left between the front ends of the left support strip 14 and the right support strip 16 and the front door frame 21. The side wall of the lower cavity has an air inlet 19.

[0033] Specifically, see Figure 4 , on the front side of the front door frame 21, there is a front protective cover 24 installed.

[0034] Specifically, on the rear side of the rear door frame 31, there is a rear protective cover (not shown in the figure) installed.

[0035] Specifically, see Figure 4 , both vertical frame strips of the front door frame 21 are provided with multiple pairs of screw holes. The louver of the front door frame 21 is a detachable louver 25. Both ends of the detachable louver 25 have folding pieces 251. Each folding piece 251 has a pair of through holes, and the folding piece 251 is connected to the front door frame 21 by screws.

[0036] Specifically, the cross-sections of the left support strip 14 and the right support strip 16 are both L-shaped.

[0037] Specifically, see Figure 3 , the cross-section of the left connecting piece 13 is U-shaped.

[0038] Specifically, see Figure 3 , the cross-section of the right connecting piece 15 is in the shape of multiple U-shaped connected end to end.

[0039] Specifically, see Figures 1 to 3 , there are ventilation gaps 111 left between the left and right side edges of the horizontal plate 11 and the left and right inner walls of the cabinet body. The ventilation gaps 111 connect the upper cavity and the lower cavity. Above the right side edge of the horizontal plate 11, there is a fixedly installed vertical plate 112. On the outer wall of the vertical plate 112, there is an electrical component 113, and the electrical component 113 is located above the right ventilation gap 111.

[0040] The working principle of the high-efficiency heat dissipation cabinet of the present utility model is as follows:

[0041] Ventilation gap 111 connects the upper and lower chambers. Electrical components 113 are located above ventilation gap 111 on the right side. When an exhaust fan (not shown) mounted on fan frame 23 rotates, negative pressure is generated in exhaust space 17, causing air in the lower chamber to flow upward through ventilation gap 111 into the upper chamber. This airflow over electrical components 113 removes heat from them, maintaining a relatively low temperature. External air enters the lower chamber through air inlet 19, balancing the pressure in the lower chamber.

[0042] Meanwhile, outside air enters the upper chamber through the louvers of the rear door frame 31 and flows through the gap between two adjacent switches (not shown), removing heat from the switches and keeping them at a relatively low temperature. In this way, the airflow driven by the exhaust fan (not shown) simultaneously creates both bottom-up and back-to-front airflow, cooling the electrical components 113 and the switches (not shown), respectively, achieving efficient heat dissipation.

[0043] When it is necessary to increase the air flow of the exhaust fan (not shown), the plurality of detachable shutters 25 can be removed (see FIG. Figure 4 ) to improve heat dissipation.

[0044] The cross section of the left connecting piece 13 is in the shape of a U, and the cross section of the right connecting piece 15 is in the shape of multiple Us connected end to end, so as to increase the surface heat dissipation area, thereby improving the heat dissipation rate of the switch (not shown).

[0045] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
