[0016] Compared with the prior art, the present invention has the following beneficial effects: 1.

When in use, the cooling fins first absorb the heat of the high-temperature gas in the central tank to turn the high-temperature gas into low-temperature gas, and then the fan blows the low-temperature gas into the air receiving slot and the transmission shell, and the low-temperature gas then moves along the air outlet holes to the component mounting rack to cool the electrical components. At this time, the low-temperature gas absorbs the heat of the electrical components and turns into high-temperature gas, which then moves to the circulation chamber. Since the gas density of the high-temperature gas is relatively low, the high-temperature gas rises into the central tank, and this process is circulated to achieve cooling of the electrical components. The advantages of the present invention also include: First point: The circulating gas cools down the electrical components. The gas flow path is smooth, so the heat dissipation effect is better, making the temperature around the electrical components appropriate, so the electrical components will not be damaged by the temperature, thus having a better protection effect on the electrical components; Second point: The heat of the gas is absorbed by the cooling plate, which further improves the heat dissipation effect; Therefore, the heat dissipation effect in the electrical cabinet of the present invention is better, and the electrical components will not be damaged due to temperature.

[0017] 2. In a gas circulation heat dissipation electrical cabinet of the present invention, one side of the refrigeration fin is connected to one side of a refrigerator, the mounting frame includes a left connecting plate, a mounting plate, and a right connecting plate, and the fan includes a motor, a rotating shaft, and fan blades. During use, the refrigerator ensures that the heat absorbed by the refrigeration fin can be dissipated to the outside of the electrical cabinet. The fan accelerates the low-temperature gas so that it enters the transmission shell more quickly and then moves more quickly from the air outlet to the electrical components to cool the electrical components. Simultaneously, the left connecting plate and the right connecting plate guide the low-temperature gas so that it moves toward the electrical components. Therefore, the present invention has a high heat dissipation efficiency.

[0018] 3. In a gas circulation heat dissipation electrical cabinet of the present invention, a left air vent and a right air vent are respectively provided on both sides of the cabinet body. The left air vent is externally covered by a left filter device, and the right air vent is externally covered by a right filter device. The left filter device and the right filter device have the same structure. The left filter device includes a frame and a filter screen. The frame and the filter screen are detachably connected. When in use, the left and right air vents are connected to the outside to help cool the electrical cabinet. The filter screen covers the outside of the left and right air vents to prevent dust from entering the electrical cabinet. After long-term use of the electrical cabinet, a large amount of dust adheres to the filter screen. At this time, the filter screen can be removed from the frame for cleaning, and then the cleaned filter screen is installed on the frame to ensure the ventilation effect of the left and right air vents. Therefore, the ventilation effect of the present invention is better.

[0019] 4. In a gas circulation heat dissipation electrical cabinet of the present invention, the cabinet body includes a cabinet door and a housing, the cabinet door and housing being hingedly connected. The cabinet body is located within a protective assembly, which includes a bottom plate, a protective frame, and a baffle. The protective frame is provided with a telescopic rod, the top of which is connected to the baffle. When in use, after closing the cabinet door, the telescopic rod is raised to raise the baffle. At this time, the baffle is located in front of the cabinet door, so the cabinet door cannot be opened outward, thereby achieving a theft-proof effect for the electrical components in the cabinet body. Therefore, the present invention has a good anti-theft effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The supplementary description of the present invention is as follows: The cooling plate 22 described in the present invention refers to: a semiconductor cooling plate. The cooling plate 22 absorbs the heat in the concentrating tank 21 from one side facing the concentrating tank 21, and then dissipates the heat from the other side of the refrigerator 22.

During use, the temperature parameters of the semiconductor cooling plate are set to control the temperature in the cabinet 1 to avoid the generation of water vapor in the cabinet 1 and affecting the electrical components.

[0047] Example 1: See Figure 1 — Figure 14 , an electrical cabinet with gas circulation heat dissipation, the electrical cabinet includes a cabinet body 1, a cooling mechanism 2 and a heat dissipation component 3; the cooling mechanism 2 is located at the top of the cabinet body 1, the middle part of the cooling mechanism 2 is a centralized tank 21, the top of the centralized tank 21 is provided with a cooling fin 22, the centralized tank 21 is located on one side of the cooling fin 22 and is provided with a fan 23, the bottom of the centralized tank 21 is evenly distributed with a plurality of connecting grooves 24, the connecting grooves 24 are connected to the top of the circulation chamber 11 of the cabinet body 1; the cabinet body 1 is located below the fan 23 A heat dissipation component 3 is provided on the square part, and the heat dissipation component 3 includes an air receiving slot 31, a conveying shell 32 and a component mounting frame 33. The top of the air receiving slot 31 is connected with one end of the bottom of the central slot 21, and the top of the air receiving slot 31 is located below the fan 23. The other end of the air receiving slot 31 is connected with one end of the conveying shell 32. The end of the conveying shell 32 facing the circulation chamber 11 is connected to one end of the component mounting frame 33. A plurality of air outlet holes 321 are evenly distributed on the end of the conveying shell 32 facing the component mounting frame 33.

[0048] When in use, the refrigeration plate 22 first absorbs the heat of the high-temperature gas in the concentrated tank 21, and then the high-temperature gas becomes low-temperature gas. The fan 23 then blows the low-temperature gas toward the air receiving tank 31, and then the low-temperature gas flows downward along the air receiving tank 31. The low-temperature gas then flows along multiple air outlets 321 toward the component mounting rack 33, and then the low-temperature gas absorbs the heat of the electrical components on the component mounting rack 33. At this time, the low-temperature gas becomes high-temperature gas, and the high-temperature gas continues to move to the circulation chamber 11. Since the density of the high-temperature gas is relatively small, the high-temperature gas moves upward, and then the high-temperature gas passes through the connecting tank 24 and reaches the concentrated tank 21. The above process is repeated to generate circulating gas in the cabinet 1, and the circulating gas continuously cools the electrical components to protect the electrical components.

[0049] Example 2: The basic content is the same as Example 1, except that: See Figure 1 — Figure 4 The side of the cooling fin 22 away from the centralizing tank 21 is connected to a side of the refrigerator 25, and the top of the refrigerator 25 is higher than the top of the cabinet 1.

Preferably, the cooling mechanism 2 includes a temperature sensor 7 , the temperature sensor 7 is electrically connected to the refrigerator 25 , and the refrigerator 25 is electrically connected to the cooling fins 22 .

[0050] During use, the temperature sensor 7 detects the temperature inside the cabinet 1. When the temperature inside the cabinet 1 reaches a certain high temperature, the cooling plate 22 and the refrigerator 25 are started, and the cooling plate 22 absorbs the heat in the concentrated tank 21. At the same time, the cooling plate 22 dissipates heat on the side away from the concentrated tank 21, and the refrigerator 25 ensures the heat dissipation effect of this side. The output end of the motor 231 drives the rotating shaft 232 to rotate, and the rotating shaft 232 drives the fan blade 233 to rotate, and then the fan blade 233 rotates to make the low-temperature gas flow toward the transmission shell 32, and the low-temperature gas Then it flows downward along the conveying shell 32, and then the low-temperature gas flows out along the outlet hole 321, and then flows toward the mounting plate 332. At this time, the left connecting plate 331 and the right connecting plate 333 are located on both sides of the low-temperature gas to guide the low-temperature gas so that the low-temperature gas can flow smoothly to the mounting plate 332 to absorb the heat of the electrical components on the mounting plate 332; the left connecting plate 331 and the right connecting plate 333 also have a fixing effect on the mounting plate 332, so that the position of the mounting plate 332 is stable, thereby stabilizing the position of the electrical components on the mounting plate 332.
