Description

Technical Field

[0001] This utility model belongs to the field of dustproof cabinet technology, specifically relating to a water-cooled electrical cabinet that does not require external circulating water. Background Technology

[0002] In certain industries, such as aerospace, aviation, and food processing, large amounts of conductive dust, such as carbon fiber dust and flour dust, are generated during production. If this dust enters the cabinet, it will adhere to electrical components, affecting their conductivity and easily causing short circuits, burnouts, and other malfunctions. Furthermore, dust accumulation can impair heat dissipation, leading to overheating, accelerated equipment aging, and even potential fires due to electric arcing. Therefore, to ensure the safe and stable operation of equipment, it is necessary to design cabinets that can effectively prevent conductive dust from entering and provide effective heat dissipation. Traditional electrical cabinets are mostly fan-ventilated or externally mounted air conditioners, with poor sealing, making it difficult to effectively block dust. Frequent dust-related malfunctions not only increase maintenance costs but may also lead to greater economic losses due to the difficulty of timely repairs caused by the shortage of certain electrical components. Therefore, from the perspective of economic cost and maintenance difficulty, it is also necessary to develop a conductive dust-proof cabinet that can operate stably for a long time, reduces the frequency of malfunctions, and has a cooling system. Summary of the Invention

[0003] The present invention aims to solve the technical problems existing in the prior art and provide a water-cooled electrical cabinet that does not require external circulating water.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a water-cooled electrical cabinet that does not require external circulating water, including a cabinet body, a partition plate is provided inside the cabinet body, and fan mounting holes and heat dissipation windows are respectively opened on the two sides of the cabinet body above the partition plate. The fan mounting holes are located on the left side of the cabinet body, and the heat dissipation windows are located on the right side of the cabinet body. A cooling fan is installed in the fan mounting holes. A filter housing is provided on the inner side of the cooling fan facing the cabinet body. A filter screen is provided inside the filter housing, and a wind speed measuring instrument is provided on the filter housing.

[0005] A heat exchange plate assembly is provided in the cabinet on the upper side of the partition, and a heat exchange tube assembly is provided in the cabinet on the lower side of the partition. The heat exchange plate assembly includes a heat exchange tube plate, which is located on the upper surface of the partition. Multiple air guide plates are provided between the heat exchange tube plate and the filter housing.

[0006] The heat exchange tube assembly includes a copper mounting plate and a water storage tank. The copper mounting plate is mounted on the water storage tank. A circulating copper tube is mounted on the rear surface of the copper mounting plate and is connected to the water storage tank. The circulating copper tube is welded to the copper mounting plate. The rear surface of the copper mounting plate is provided with multiple fins that simultaneously surround the circulating copper tube. Both the circulating copper tube and the heat exchange tube plate include an inlet and an outlet. The inlet and outlet of the heat exchange tube plate extend through a partition to the lower surface of the partition. The inlet of the circulating copper tube is connected to the outlet of the heat exchange tube plate, and the outlet of the circulating copper tube is connected to the inlet of the heat exchange tube plate. A circulating water pump is provided at the inlet end of the heat exchange tube plate.

[0007] Preferably, the bottom of the cabinet is provided with a splicing through-wall panel.

[0008] Preferably, the water storage tank is provided with a drain outlet at the bottom, and the inlet of the circulating copper pipe is provided with a water injection pipe.

[0009] Preferably, the cabinet includes a cabinet door, on which a temperature probe and a temperature controller are installed.

[0010] The beneficial effects of this utility model are as follows: The cabinet is divided into upper and lower parts by a partition, and the heat generated in the lower part of the cabinet is transferred to the upper heat exchange plate assembly through a heat exchange tube assembly. The heat exchange plate assembly is cooled by a cooling fan, thereby achieving temperature reduction inside the cabinet and preventing the lower part of the cabinet from being connected to the outside, which would cause dust to enter and affect the operation of the equipment. By setting an integrated copper mounting plate and circulating copper pipe, the shell increases the thermal conductivity of the equipment installed on its surface. The heat is quickly transferred to the heat exchange plate assembly for cooling through the circulating copper pipe. The addition of fins can further improve the heat exchange efficiency of the copper mounting plate and circulating copper pipe. Attached Figure Description

[0018] Example: A water-cooled electrical cabinet that does not require external circulating water, such as Figures 1-5 As shown, the cabinet includes a cabinet body 1. Inside the cabinet body 1, there is a partition 2. On the upper side of the partition 2, on both sides of the cabinet body 1, there are fan mounting holes 3 and heat dissipation windows 4 respectively. The fan mounting holes 3 are located on the left side of the cabinet body 1, and the heat dissipation windows 4 are located on the right side of the cabinet body 1. A cooling fan 5 is installed in the fan mounting hole 3. A filter housing 6 is provided on the inner side of the cooling fan 5 facing the cabinet body 1. A filter screen 7 is provided inside the filter housing 6. An anemometer 8 is provided on the filter housing 6.

[0019] The cabinet 1 on the upper side of the partition 2 is provided with a heat exchange plate assembly 9, and the cabinet 1 on the lower side of the partition 2 is provided with a heat exchange tube assembly 10. The heat exchange plate assembly 9 includes a heat exchange tube plate 11, which is located on the upper surface of the partition 2. Multiple air guide plates 12 are provided between the heat exchange tube plate 11 and the filter housing 6.

[0020] The heat exchanger tube assembly 10 includes a copper mounting plate 13 and a water storage tank 23. The copper mounting plate 13 is mounted on the water storage tank 23. A circulating copper pipe 14 is mounted on the rear surface of the copper mounting plate 13. The circulating copper pipe 14 is connected to the water storage tank 23 and is welded to the copper mounting plate 13. The rear surface of the copper mounting plate 13 is provided with multiple fins 15, which simultaneously surround the circulating copper pipe 14. The copper mounting plate 13 has screws for mounting electrical equipment. The holes and screw holes are all set to avoid the fins 15 and the circulating copper tube 14. The circulating copper tube 14 and the heat exchange tube plate 11 each include an inlet 16 and an outlet 17. The inlet 16 and outlet 17 of the heat exchange tube plate 11 extend through the partition 2 to the lower surface of the partition 2. The inlet 16 of the circulating copper tube 14 is connected to the outlet 17 of the heat exchange tube plate 11, and the outlet 17 of the circulating copper tube 14 is connected to the inlet 16 of the heat exchange tube plate 11. A circulating water pump 18 is provided at the inlet 16 end of the heat exchange tube plate 11.

[0021] The bottom of the cabinet 1 is provided with a spliced ​​through-wall panel 19; the bottom of the water storage tank 23 is provided with a drain outlet 20, and the inlet 16 of the circulating copper pipe 14 is provided with a water injection pipe 24; the cabinet 1 includes a cabinet door, and the cabinet door is provided with a temperature probe 21 and a temperature controller 22.

[0022] The principle of this invention is as follows: Water is circulated within the cabinet via a circulating water pump 18, transporting the heated water to the heat exchange plate assembly 9. A cooling fan 5 directs outside air through a guide plate to ensure sufficient contact between the air and the heat exchange tube plate 11, effectively cooling the circulating water and enabling its reuse. A temperature probe 21PT100 feeds back the cabinet temperature to a temperature controller. When the set temperature (35℃) is reached, the temperature controller activates the cooling fan 5 to cool the circulating water. When the temperature is below the set temperature, the cooling fan 5 is not activated, saving energy. An anemometer 8 is installed at the filter housing 6, detecting wind speeds below 10 m³ / h. If the filter 7 is found to be clogged when the fan is running at a speed of / min and the airflow tester is activated, an alarm will be triggered so that the filter 7 can be replaced in time. The upper cabinet 1 is isolated from the electrical installation room by the partition 2 (with a protection level of IP55 or above). Even if some dust enters the upper cabinet 1 through the filter 7, it can effectively prevent charged dust from entering the lower cabinet 1, thus achieving effective isolation. The cables inside the cabinet are connected to the bottom modular wall plate, which ensures both the convenience of wiring and the protection level of the cabinet. A liquid level sensor can be installed in the water tank 23 to monitor the height of the coolant. When the liquid level is low, water can be added from the water injection pipe 24 in time.
