DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Reference Figure 1-Figure 5 The present invention provides a safe and environmentally friendly heat dissipation mechanism for a high-voltage cabinet, comprising:

[0041] A plurality of air inlet channels 2 and a plurality of air exhaust channels 3, wherein the plurality of air inlet channels 2 and the plurality of air exhaust channels 3 are respectively arranged on two opposite side walls of the cabinet body 1;

[0042] The heat dissipation assembly includes a plurality of heat dissipation elements, which are rotatably connected to the cabinet body 1 along the axial direction and are respectively connected to a plurality of air inlet passages 2. The heat dissipation elements are used to blow external air to the electrical appliances inside the cabinet body 1;

[0043] A pushing component is arranged in the cabinet body 1 and connected to the heat sink, and is configured to adjust the angle of the heat sink and close the heat sink when the pushing component moves upward;

[0044] The dustproof assembly includes a plurality of dustproof nets 4 and a plurality of cleaning pieces. The plurality of dustproof nets 4 are fixedly connected to the air inlet passage 2 and the plurality of exhaust passages 3 , respectively. The cleaning pieces are arranged on the dustproof nets 4 to clean the dust adsorbed by the dustproof nets 4 .

[0045] Specifically, in the initial state, air is taken in through the set air intake channel 2. During air intake, air is blown toward the electrical appliances inside the cabinet body 1 through the set heat sink, and the electrical appliances are cooled and dissipated. At the same time, air is discharged from the exhaust channel 3 to realize air circulation, thereby ensuring the heat dissipation effect. When the heat dissipation efficiency is low, it is pushed upward by the set pushing component, and the heat sink is driven to rotate and close the heat sink during the pushing. When the pushing component moves upward, it pushes the air in the cabinet body 1 to flow out from the exhaust channel 3, increasing the gas discharge amount. Conversely, when the pushing mechanism is reset, the heat sink is driven to open and connect with the air intake channel 2. The pulling and pulling of the pushing mechanism drives the increase of the flow rate of external air entering the cabinet body 1. Repeating the operation increases the air flow rate inside the cabinet body 1 through the pushing mechanism, thereby improving the heat dissipation efficiency. In addition, the dustproof net 4 is set to prevent external dust from entering the cabinet body 1, and the dustproof net 4 is cleaned by the set cleaning member to avoid clogging of the dustproof net 4, thereby ensuring air circulation and heat dissipation efficiency.

[0046] As an optional embodiment, the heat sink includes: a fixing plate 5, fixedly connected to the cabinet body 1 through a supporting rod 6;

[0047] The tube body 7 is rotatably connected to the fixed plate 5, and one end of the tube body 7 is rotatably connected to the air inlet passage 2.

[0048] Specifically, refer to Figure 1 , Figure 5The tube body 7 rotates to condense on the fixed plate 5, and transports air to the inside of the cabinet body 1 through the exhaust hole 8, and blows to the corresponding electrical appliances for heat dissipation. When the tube body 7 rotates, the exhaust hole 8 is driven to rotate, thereby achieving blowing in different directions and improving the heat dissipation efficiency. As the tube body 7 rotates, when the exhaust hole 8 contacts the fixed plate 5, the exhaust hole 8 is sealed.

When the horizontal plate 9 moves upward, the first tooth plate 11 on the side plate 10 and the first gear 12 on the tube body 7 drive the tube body 7 to rotate, and finally realize the sealing of the tube body 7. After sealing, as the horizontal plate 9 moves upward, the air inside the compressor cabinet body 1 flows out from the exhaust channel 3. On the contrary, the tube body 7 is opened and the outside air flows into the cabinet body through the tube body 7, increasing the outside air inflow flow, and finally improving the overall air flow and the heat dissipation efficiency.
