Description

Technical Field

[0001] This utility model relates to the field of low-voltage cabinet technology, specifically to a low-voltage cabinet with a circulating heat dissipation structure. Background Technology

[0002] Low-voltage switchgear is a product used for converting and configuring electrical energy. The rated current of the low-voltage switchgear is AC 50Hz, and the rated voltage is 380V. It is used for power, lighting and power distribution energy conversion and control. This product has the characteristics of strong breaking capacity, good dynamic and thermal stability, flexible electrical scheme, convenient combination, strong practicality and novel structure.

[0003] Currently, in order to facilitate the heat dissipation of electrical components installed in low-voltage cabinets, existing heat dissipation mechanisms are all single air intake or exhaust types, which blow external air into the cabinet or extract hot air from the cabinet to achieve the purpose of heat dissipation, resulting in low heat dissipation efficiency. Therefore, a circulating heat dissipation structure low-voltage cabinet is proposed, which adopts a circulating design. External air enters the low-voltage cabinet, and hot air inside the low-voltage cabinet is blown out, accelerating the flow of air inside the low-voltage cabinet and achieving high heat dissipation efficiency. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a low-pressure cabinet with a circulating heat dissipation structure. It adopts a circulating design, in which external gas enters the low-pressure cabinet and hot gas inside the cabinet is blown out, accelerating the flow of gas inside the low-pressure cabinet and achieving high heat dissipation efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is a low-voltage cabinet with a circulating heat dissipation structure, including a low-voltage cabinet, a side plate fixed to one side of the low-voltage cabinet by bolts, a frame fixed to the side of the side plate away from the low-voltage cabinet by bolts, a serpentine tube installed inside the frame by a mounting bracket, and fins equidistantly sleeved on the outside of the serpentine tube.

[0006] The low-voltage cabinet is provided with an air outlet assembly on one side of the bottom of the frame. The air outlet assembly includes a first ventilation box that is fixed to one side of the side plate by bolts. An exhaust fan is installed inside the first ventilation box by a mounting bracket. An air inlet assembly is provided on one side of the frame. The air inlet assembly includes a fan that is installed inside a second ventilation box by a mounting bracket.

[0007] By adopting the above technical solution, the fan draws external gas into the low-pressure cabinet, and the exhaust fan draws out the hot gas in the low-pressure cabinet, accelerating the flow of gas in the low-pressure cabinet. When the external cooling water flows in the serpentine tube, its temperature is conducted to the fins.

[0008] Specifically, the inlet and outlet ends of the serpentine tube are respectively connected to an inlet valve and an outlet valve via threaded grooves, and both the inlet valve and the outlet valve are located outside the low-pressure cabinet.

[0009] Specifically, the second ventilation box has a first through hole at equal intervals on one side, the first through hole penetrates the frame, and the second ventilation box has a first dustproof net fixed inside the side away from the fan by bolts.

[0010] Specifically, a second through hole is provided at equal intervals on one side of the first ventilation box, the second through hole penetrates the side plate, and a second dustproof net is fixed inside the first ventilation box on the side of the exhaust fan with bolts.

[0011] Specifically, the side panel has a reserved groove inside the second ventilation box, and the two sides of the reserved groove are connected to the low-voltage cabinet and the frame, respectively.

[0012] Specifically, the frame is made of fiberglass material, and the fins are made of aluminum alloy material.

[0013] The beneficial effects of this utility model are:

[0014] This invention relates to a low-voltage cabinet with a circulating heat dissipation structure. When the fan is turned on, external air is drawn into a second ventilation box and blown into the low-voltage cabinet through multiple first through-holes and pre-reserved slots. The external air neutralizes the hot air inside the low-voltage cabinet. When the exhaust fan is turned on, the hot air inside the low-voltage cabinet is extracted through multiple second through-holes, accelerating the airflow within the cabinet and resulting in high heat dissipation efficiency. Furthermore, the invention also utilizes an inlet and outlet valve to allow external cooling water to flow within a serpentine tube. After entering the serpentine tube, the cooling water is conducted to the fins. When the fan is operating, it blows the cool air from the fins into the low-voltage cabinet, further cooling the interior and achieving high cooling efficiency. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] The system employs a circulating design, where external air enters the low-pressure cabinet, and hot air is blown out, accelerating airflow within the cabinet and resulting in high heat dissipation efficiency. Figure 1-5 As shown, the low-voltage cabinet with circulating heat dissipation structure of this utility model includes a low-voltage cabinet 1. A side plate 2 is fixed to one side of the low-voltage cabinet 1 by bolts. A frame 3 is fixed to the side of the side plate 2 away from the low-voltage cabinet 1 by bolts. A serpentine tube 6 is installed inside the frame 3 by a mounting bracket. Fins 7 are equidistantly sleeved on the outside of the serpentine tube 6.

[0024] The low-voltage cabinet 1 is provided with an air outlet assembly 5 on one side of the bottom of the frame 3. The air outlet assembly 5 includes a first ventilation box 501 fixed to one side of the side plate 2 by bolts. An exhaust fan 502 is installed inside the first ventilation box 501 by a mounting bracket. An air inlet assembly 4 is provided on one side of the frame 3. The air inlet assembly 4 includes a fan 402 installed inside a second ventilation box 401 by a mounting bracket.

[0025] When in use, fan 402 draws external air into the low-pressure cabinet 1, and exhaust fan 502 draws out hot air from the low-pressure cabinet 1, accelerating the flow of air in the low-pressure cabinet 1. When external cooling water flows in the serpentine tube 6, its temperature is transferred to the fins 7.

[0026] For example, such as Figure 3 As shown, the present invention also includes a water inlet valve 8 and a water outlet valve 9 connected to the water inlet end and the water outlet end of the serpentine tube 6 respectively through threaded grooves. The water inlet valve 8 and the water outlet valve 9 are both located outside the low-pressure cabinet 1.

[0027] When in use, open the inlet valve 8 and the outlet valve 9 to allow external cooling water to flow in the serpentine pipe 6.

[0028] For example, such as Figure 4 As shown, the present invention also includes a first through hole 403 equidistantly provided on one side of the second ventilation box 401, the first through hole 403 penetrating the frame 3, and a first dustproof net 404 fixed inside the side of the first ventilation box 401 away from the fan 402 by bolts.

[0029] When in use, the opening of the first through hole 403 allows the gas in the second ventilation box 401 to be blown into the low-pressure cabinet 1, and the first dustproof net 404 can prevent external dust and other objects from entering the second ventilation box 401.

[0030] For example, such as Figure 5 As shown, the present invention also includes a second through hole 503 equidistantly provided on one side of the first ventilation box 501, the second through hole 503 penetrating the side plate 2, and a second dustproof net 504 fixed inside the first ventilation box 501 on the side of the exhaust fan 502 by bolts.

[0031] When in use, the opening of the second through hole 503 allows hot air inside the low-pressure cabinet 1 to be drawn into the first ventilation box 501, and the second dustproof net 504 can prevent external dust and other objects from entering the first ventilation box 501.

[0032] For example, such as Figure 2 As shown, the present invention also includes a reserved groove 10 inside the side plate 2 located on one side of the second ventilation box 401, and the reserved groove 10 is connected to the low-voltage cabinet 1 and the frame 3 on both sides respectively.

[0033] When in use, the opening of the reserved slot 10 ensures that the gas inside the second ventilation box 401 will not be blocked by the side plate 2.

[0034] For example, such as Figure 3 As shown, the present invention also includes that the frame 3 is made of glass fiber material and the fins 7 are made of aluminum alloy material.

[0035] When in use, the frame 3 made of fiberglass material has good heat insulation capabilities, which can reduce the amount of external heat entering the frame 3.

[0036] When using this utility model, the user connects the device to an external power source using a power cord and connects the inlet valve 8 and outlet valve 9 to an external cooling water supply device using a water pipe.

[0037] When the fan 402 is turned on, the external air is drawn into the second ventilation box 401 and blown into the low-pressure cabinet 1 through multiple first through holes 403 and reserved slots 10. The external air is neutralized with the hot air in the low-pressure cabinet 1. When the exhaust fan 502 is turned on, the hot air in the low-pressure cabinet 1 is drawn out through multiple second through holes 503, which accelerates the flow of air in the low-pressure cabinet 1 and has high heat dissipation efficiency.

[0038] Turn off the exhaust fan 502 and open the inlet valve 8 and outlet valve 9 to allow external cooling water to flow in the serpentine tube 6. After entering the serpentine tube 6, the cooling water is conducted to the fins 7. When the fan 402 is working, it can blow the cool air on the fins 7 into the low-pressure cabinet 1 to cool down the low-pressure cabinet 1. The cooling efficiency is high.
