Description

Technical Field

[0001] The present application relates to the technical field of power distribution cabinets, and in particular to an automatic switching emergency power distribution cabinet. Background Art

[0002] Distribution cabinets are key equipment in power systems, primarily used for the distribution, control, and protection of electrical energy. They are widely used in industrial, commercial, and infrastructure construction fields. In practice, the power electronics within distribution cabinets generate significant heat during operation. These devices typically include circuit breakers, disconnectors, fuses, current transformers, voltage transformers, and other components, often integrated into the main cabinet. Failure to dissipate heat promptly can lead to overheating, impacting normal operation and even damaging components. Therefore, maintaining a reasonable internal temperature range is crucial for ensuring safe and stable system operation.

[0003] Currently, the heat dissipation methods of distribution cabinets are mainly divided into air cooling and water cooling. Air cooling systems mainly rely on air flow to remove heat, while water cooling systems conduct heat through liquid circulation. Both have their advantages and disadvantages. Traditional distribution cabinets mainly use air cooling to dissipate heat. Although the air cooling system has a simple structure and is easy to maintain, the air cooling effect is limited in high temperature environments or when there is too much heat inside the distribution cabinet, and it may not be able to effectively reduce the temperature. Existing air cooling systems are easily affected by water vapor and dust in the air in humid or dusty environments, resulting in reduced fan performance or even damage. Although water cooling systems can be used in humid or dusty environments, they cannot switch intelligently according to actual load conditions and ambient temperature, resulting in high energy consumption or unstable heat dissipation effects, making it difficult to adapt to complex and changing application scenarios.

[0004] Therefore, it is necessary to propose an automatic switching emergency power distribution cabinet so that the power distribution cabinet can be intelligently switched according to the actual heat dissipation situation and ambient temperature to achieve more efficient and intelligent heat dissipation control. Summary of the Invention

[0005] The purpose of this application is to overcome the deficiencies in the prior art and propose an automatic switching emergency power distribution cabinet to solve the problem that the power distribution cabinet cannot be intelligently switched according to actual heat dissipation conditions and ambient temperature.

[0006] This application is achieved through the following technical solutions:

[0007] This application proposes an automatic switching emergency power distribution cabinet, comprising:

[0008] The cabinet body is provided with a receiving groove and an air duct, wherein the receiving groove and the air duct are connected;

[0009] The electrical cabinet host is arranged in the accommodating slot;

[0010] A heat dissipation device is connected to the electrical cabinet host, with one side of the heat dissipation device located in the air duct and the other side located in the accommodating groove;

[0011] An air cooling device is provided in the air duct, and the air cooling device can drive the air in the air duct to flow;

[0012] A water cooling device, comprising a water storage bucket and a water pipe, wherein the water storage bucket is located above the cabinet, one end of the water pipe is connected to the water storage bucket, and the other end passes through the heat dissipation device;

[0013] A temperature and humidity sensor is provided outside the cabinet and is used to detect ambient temperature and humidity;

[0014] a control module, electrically connected to the water storage tank and the temperature and humidity sensor;

[0015] When the temperature monitored by the temperature and humidity sensor is lower than a first temperature threshold and the humidity is lower than a humidity threshold, the control module controls the water storage tank to stop supplying water and controls the air cooling device to drive the air in the air duct to flow, so that the temperature of the heat dissipation device decreases;

[0016] When the humidity monitored by the temperature and humidity sensor is greater than a humidity threshold, the control module controls the air cooling device to stop running and controls the water storage tank to supply water to the water pipe, so that the temperature of the heat dissipation device drops;

[0017] When the temperature monitored by the temperature and humidity sensor is greater than a first temperature threshold, the control module controls the air cooling device to stop running and controls the water storage tank to supply water to the water pipe, so that the temperature of the heat dissipation device drops.

[0018] In one embodiment of the present application, the water cooling device further includes a two-branch pipe, a first electric valve, a second electric valve, a boost pump, and a temperature sensor. The two-branch pipe includes a first pipe and a second pipe. The first electric valve and the boost pump are connected to the first pipe, and the second electric valve is connected to the second pipe.

[0019] The control module is electrically connected to the first electric valve, the second electric valve, the boost pump and the temperature sensor;

[0020] The portion of the water pipe before passing through the heat sink is defined as a water inlet section, and the water inlet section includes a first water inlet section and a second water inlet section. One end of the first water inlet section is connected to the water storage bucket, and the other end is connected to the two-branch pipe. One end of the second water inlet section is connected to the two-branch pipe, and the other end passes through the heat sink. The first water inlet section is located above the second water inlet section.

[0021] The portion of the water pipe after passing through the heat dissipation device is defined as a water outlet section, and the temperature sensor is provided on the pipe wall of the water outlet section and close to the heat dissipation device, for monitoring the temperature of the pipe wall of the water outlet section;

[0022] The water storage tank supplies water to the water pipe. When the temperature monitored by the temperature sensor is lower than a second temperature threshold, the control module controls the booster pump and the first electric valve to close and controls the second electric valve to open, so that the water in the first water inlet section flows into the second water inlet section through the second pipe.

[0023] The water storage tank supplies water to the water pipe. When the temperature monitored by the temperature sensor is greater than a second temperature threshold, the control module controls the booster pump and the first electric valve to open, and controls the second electric valve to close, so that the water in the first water inlet section flows into the second water inlet section through the first pipe, and the booster pump drives the water in the first water inlet section to flow downward at an accelerated speed.

[0024] In one embodiment of the present application, the water storage tank is connected to an external water source, and the water storage tank is provided with an exhaust valve, and the exhaust valve is electrically connected to the control module;

[0025] When external water is supplied to the water storage tank, the control module controls the exhaust valve to open.

[0026] In one embodiment of the present application, the heat dissipation device includes a first heat dissipation member and a second heat dissipation member, the first heat dissipation member is attached to the electric cabinet host, the second heat dissipation member is attached to the first heat dissipation member, the first heat dissipation member is located in the accommodating groove, and the second heat dissipation member is located in the air duct.

[0027] In one embodiment of the present application, the second heat dissipation element includes:

[0028] a heat dissipation member comprising a plurality of first heat conduction plates, each of the first heat conduction plates being connected to the first heat dissipation member, the plurality of first heat conduction plates being arranged at equal intervals such that ventilation slots are defined between adjacent first heat conduction plates, and each of the ventilation slots being in communication with the air duct;

[0029] The heat dissipation cover comprises a back plate and a plurality of second heat conduction plates, wherein the back plate and the plurality of second heat conduction plates are bonded together, the plurality of second heat conduction plates are arranged at equal intervals, and each second heat conduction plate is bonded together with one of the first heat conduction plates. The water pipe passes through the back plate and is bonded together with the back plate.

[0030] In one embodiment of the present application, the water pipe is arranged in the back plate with multiple U-shaped bends and is spaced apart along the horizontal or vertical direction of the back plate to increase the heat conduction area between the water pipe and the back plate.

[0031] In one embodiment of the present application, the cabinet body is further provided with an air inlet and an air outlet, the air duct is connected to the air inlet and the air outlet, a plurality of second heat conduction plates are located between the air inlet and the air outlet, and the air cooling device can drive air from the air inlet through the ventilation slot to the air outlet for discharge.

[0032] In one embodiment of the present application, the air cooling device is disposed near the air inlet.

[0033] In one embodiment of the present application, a water receiving trough is provided at the bottom of the water outlet section, and the water receiving trough is used to collect cooling water flowing out of the water outlet section.

[0034] In one embodiment of the present application, the water cooling device further includes a third electric valve, the third electric valve is connected to the water outlet section, the control module is electrically connected to the third electric valve, and the water outlet section is connected to the water storage tank;

[0035] When cooling water needs to be discharged from the water outlet section, the control module controls the third electric valve to open to discharge the cooling water.

[0036] Compared with the prior art, the present invention has the following advantages:

[0037] 1. The storage tank and the air duct are connected, the electric cabinet main unit is arranged in the storage tank, the heat dissipation device is connected to the electric cabinet main unit, one side of the heat dissipation device is located in the air duct, and the other side is located in the storage tank. The air cooling device is arranged in the air duct, the water storage tank is located above the cabinet, one end of the water pipe is connected to the water storage tank, and the other end passes through the heat dissipation device. The temperature and humidity sensor is arranged outside the cabinet, and the control module is electrically connected to the water storage tank and the temperature and humidity sensor.

[0038] When the temperature and humidity sensors detect that the temperature is below the first temperature threshold and the humidity is below the humidity threshold, the ambient temperature is low and air cooling can meet the heat dissipation requirements. The control module controls the air cooling device to drive air flow in the air duct, thereby dissipating heat through air flow and accelerating the heat release of the electrical cabinet. At the same time, the water storage tank stops supplying water to reduce unnecessary energy consumption.

[0039] When the humidity is higher than the humidity threshold, it means that the emergency power distribution cabinet is automatically switched in a humid environment. The fan operation may inhale excessive water vapor, causing damage to the air cooling device or reducing efficiency. Therefore, the control module turns off the air cooling device and starts the water cooling device to prevent the air cooling device from being affected by moisture while ensuring the heat dissipation effect.

[0040] When the temperature exceeds the first threshold, the emergency power distribution cabinet automatically switches to the emergency power distribution cabinet. In extremely high temperatures, air cooling may not be able to effectively reduce the temperature of the cabinet main unit, affecting stable equipment operation. The control module automatically switches to the water cooling device, opens the water storage tank to supply water to the water pipe, and enables the water cooling device to reduce the temperature and improve heat dissipation efficiency. At the same time, the air cooling device is turned off to reduce unnecessary energy consumption.

[0041] 2. A first heat sink is bonded to the main unit of the electrical cabinet and is used to directly absorb heat generated by the main unit. A second heat sink is bonded to the first heat sink and further transfers heat from the first heat sink to the second heat sink. The second heat sink includes a heat guide and a heat cover. The heat guide includes multiple first heat conduction plates, each connected to the first heat sink. The multiple first heat conduction plates are evenly spaced, with ventilation slots defined between adjacent first heat conduction plates. Each ventilation slot is connected to an air duct, allowing air flow. The air cooling device drives air flow within the air duct, thereby improving heat removal efficiency. The heat cover includes a backplate and multiple second heat conduction plates. The backplate and multiple second heat conduction plates are bonded to each other. The multiple second heat conduction plates are evenly spaced, and each second heat conduction plate is bonded to one of the first heat conduction plates. A water pipe passes directly through the backplate and is bonded to it. Dynamic switching is controlled by a control module and temperature and humidity sensors, ensuring that the main unit of the power distribution cabinet maintains optimal heat dissipation under various environmental conditions. The heat dissipation efficiency is optimized through the combination of air cooling and water cooling devices, allowing the distribution cabinet to adapt to complex operating environments and maintain stable operation for a long time.

[0042] 3. The water pipes, instead of being arranged in a straight line as they pass through the backplane, form multiple U-shaped bends and are spaced at intervals along the horizontal or vertical axis of the backplane. This design extends the water pipe's flow path within the backplane, thereby increasing the contact area between the water pipe and the backplane and enhancing heat transfer efficiency. In water-cooling mode, the cooling water flowing through the water pipes can fully absorb the heat transferred from the heat dissipation cover and the heat dissipation device, and continuously removes the heat to improve heat dissipation efficiency. Furthermore, the multiple U-shaped bends in the water pipe layout prevent insufficient cooling caused by excessive water flow, ensuring sufficient heat exchange.

[0060] Please refer to Figures 1 to 7 The present application proposes an automatic switching emergency power distribution cabinet 10, comprising a cabinet body 100, a cabinet main unit 200, a heat dissipation device 300, an air cooling device 400, a water cooling device 500, a temperature and humidity sensor 600, and a control module (not marked in the figure). The cabinet body 100 is provided with a receiving groove 110 and an air duct 120, and the receiving groove 110 and the air duct 120 are connected; the cabinet main unit 200 is arranged in the receiving groove 110; the heat dissipation device 300 is connected to the cabinet main unit 200, one side of the heat dissipation device 300 is located in the air duct 120, and the other side is located in the receiving groove 110. 0; the air cooling device 400 is provided in the air duct 120, and the air cooling device 400 can drive the air flow in the air duct 120; the water cooling device 500 includes a water storage bucket 510 and a water pipe 520, the water storage bucket 510 is located above the cabinet 100, one end of the water pipe 520 is connected to the water storage bucket 510, and the other end passes through the heat dissipation device 300; the temperature and humidity sensor 600 is provided outside the cabinet 100 for detecting the ambient temperature and humidity; the control module is provided in the electrical cabinet host 200, and the control module is electrically connected to the water storage bucket 510 and the temperature and humidity sensor 600;

[0061] When the temperature monitored by the temperature and humidity sensor 600 is lower than the first temperature threshold and the humidity is lower than the humidity threshold, the control module controls the water storage tank 510 to stop supplying water and controls the air cooling device 400 to drive the air flow in the air duct 120, so that the temperature of the heat dissipation device 300 decreases;

[0062] When the humidity monitored by the temperature and humidity sensor 600 is greater than the humidity threshold, the control module controls the air cooling device 400 to stop running and controls the water storage tank 510 to supply water to the water pipe 520, so that the temperature of the heat dissipation device 300 decreases;

[0063] When the temperature monitored by the temperature and humidity sensor 600 is greater than the first temperature threshold, the control module controls the air cooling device 400 to stop running and controls the water storage tank 510 to supply water to the water pipe 520, so that the temperature of the heat dissipation device 300 drops.

[0064] Specifically, the control module is a control circuit board installed on the electrical cabinet main unit 200. The cabinet 100 is equipped with a receiving slot 110 and an air duct 120. The receiving slot 110 and the air duct 120 are interconnected. The electrical cabinet main unit 200 is located within the receiving slot 110 and connected to the air duct 120 via a heat sink 300. One side of the heat sink 300 is located within the air duct 120, while the other side is connected to the electrical cabinet main unit 200, enabling heat transfer. An air cooling device 400 is installed within the air duct 120, driving air flow to reduce the temperature of the heat sink 300. A water cooling device 500 includes a water tank 510 and a water pipe 520. The water tank 510 is located above the cabinet 100. One end of the water pipe 520 is connected to the water tank 510, and the other end passes through the heat sink 300 to provide liquid cooling. A temperature and humidity sensor 600 is located on the outside of the cabinet 100 to detect ambient temperature and humidity and transmit the data to the control module, enabling intelligent switching of cooling methods.

[0065] When the temperature and humidity sensor 600 detects that the temperature is below the first temperature threshold and the humidity is below the humidity threshold, the ambient temperature is low and air cooling can meet the heat dissipation requirements. The control module controls the air cooling device 400 to drive air flow in the air duct 120, thereby dissipating heat through air flow and accelerating the release of heat from the heat dissipation device 300. At the same time, the water storage tank 510 stops supplying water to reduce unnecessary energy consumption.

[0066] When the humidity exceeds the threshold, the automatic switchover occurs. Emergency power distribution cabinet 10 is operating in a humid environment, and the fan operation may draw in excessive moisture, damaging air cooling device 400 or reducing its efficiency. The control module shuts down air cooling device 400 and activates water cooling device 500, protecting air cooling device 400 from moisture while ensuring effective heat dissipation.

[0067] When the temperature exceeds the first temperature threshold, the emergency power distribution cabinet 10 automatically switches to a different mode. In an extremely high-temperature environment, air cooling may not effectively reduce the temperature of the cabinet mainframe 200, affecting stable equipment operation. The control module automatically switches to the water cooling device 500, opening the water storage tank 510 to supply water to the water pipe 520, allowing the water cooling device 500 to achieve its cooling effect and improve heat dissipation efficiency. At the same time, the air cooling device 400 is turned off to reduce unnecessary energy consumption.

[0068] The design of the above solution ensures that the automatic switching emergency power distribution cabinet 10 can adaptively switch to a suitable cooling mode according to actual cooling requirements and environmental changes, thereby achieving efficient cooling and stable system operation.

[0069] It is important to understand that, at present, the heat dissipation methods of power distribution cabinets are mainly divided into two types: air cooling and water cooling. Air cooling relies on fans to drive air flow for heat dissipation. It has the characteristics of simple structure and easy maintenance. However, in high-temperature environments, the heat dissipation efficiency of air cooling is limited, and it is difficult to meet the needs of long-term stable operation of power distribution cabinets. In addition, in humid and dusty environments, fans are easily affected by water vapor and dust, resulting in performance degradation or even damage. Water cooling uses liquid circulation to exchange heat and has a good heat dissipation effect in high-temperature and closed environments. However, its cost requirements are high, and traditional water cooling systems often cannot switch intelligently according to the actual heat dissipation effect and ambient temperature, resulting in high energy consumption and unstable operating efficiency. Therefore, a single air cooling or water cooling method has limitations. Under different environmental conditions, air cooling and water cooling each have limitations and cannot take into account heat dissipation efficiency, equipment stability and energy consumption optimization.

[0070] In the present application, the automatic switching emergency distribution cabinet 10 combines air cooling and water cooling, and dynamically switches through the control module and the temperature and humidity sensor 600, so that the distribution cabinet can always maintain the best heat dissipation state under different environmental conditions, avoiding the disadvantages of the single heat dissipation method in the existing technology, thereby improving the heat dissipation capacity of the distribution cabinet, reducing energy consumption, and enhancing the adaptability of the equipment in complex environments.

[0071] In summary, by intelligently switching between air cooling and water cooling, automatically monitoring environmental conditions and optimizing heat dissipation methods, efficient and intelligent heat dissipation management of the power distribution cabinet can be achieved without manual intervention. This ensures that the power distribution cabinet can maintain optimal heat dissipation in different environments, avoiding the limitations of a single heat dissipation method. In low-temperature or dry environments, air cooling is preferred to avoid unnecessary water cooling operation. In high-temperature or humid environments, water cooling is switched to improve heat dissipation efficiency while reducing energy consumption. Through real-time monitoring by the temperature and humidity sensor 600, fans are prevented from being damaged by operation in humid environments, improving system stability. This is particularly suitable for high-humidity, high-temperature, and dusty environments. At the same time, fan failure due to water vapor accumulation is avoided, improving the reliability and durability of the entire system.

[0072] Please refer to Figure 1 In one embodiment, the water cooling device 500 further includes a two-branch pipe 530, a first electric valve 540, a second electric valve 550, a booster pump 570, and a temperature sensor 580. The two-branch pipe 530 includes a first pipe 531 and a second pipe 532. The first electric valve 540 and the booster pump 570 are connected to the first pipe 531, and the second electric valve 550 is connected to the second pipe 532.

[0073] The control module is electrically connected to the first electric valve 540, the second electric valve 550, the boost pump 570 and the temperature sensor 580;

[0074] The portion of the water pipe 520 before passing through the heat sink 300 is defined as a water inlet section (not labeled in the figure). The water inlet section includes a first water inlet section 521 and a second water inlet section 522. One end of the first water inlet section 521 is connected to the water storage tank 510 and the other end is connected to the two-branch pipe 530. One end of the second water inlet section 522 is connected to the two-branch pipe 530 and the other end passes through the heat sink 300. The first water inlet section 521 is located above the second water inlet section 522.

[0075] The portion of the water pipe 520 after passing through the heat sink 300 is defined as the water outlet section 523. The temperature sensor 580 is disposed on the wall of the water outlet section 523 and close to the heat sink 300 to monitor the temperature of the wall of the water outlet section 523.

[0076] The water storage tank 510 supplies water to the water pipe 520. When the temperature monitored by the temperature sensor 580 is lower than the second temperature threshold, the control module controls the booster pump 570 and the first electric valve 540 to close and the second electric valve 550 to open, so that the water in the first water inlet section 521 flows into the second water inlet section 522 through the second pipe 532.

[0077] The water storage tank 510 supplies water to the water pipe 520. When the temperature monitored by the temperature sensor 580 is greater than the second temperature threshold, the control module controls the boost pump 570 and the first electric valve 540 to open and controls the second electric valve 550 to close, so that the water in the first water inlet section 521 flows into the second water inlet section 522 through the first pipe 531, and the boost pump 570 drives the water in the first water inlet section 521 to flow downward at an accelerated speed.

[0078] Specifically, the first water inlet section 521 and the second water inlet section 522 are connected at both ends of the bifurcated pipe 530. The bifurcated pipe 530 is divided into a first pipe 531 and a second pipe 532. The first pipe 531 connects to the first electric valve 540 and the boost pump 570, while the second pipe 532 connects to the second electric valve 550, thereby achieving water flow distribution and control. The portion of the water pipe 520 before entering the heat dissipation device 300 is the water inlet section, which is divided into a first water inlet section 521 and a second water inlet section 522. The first water inlet section 521 connects the water storage tank 510 and the bifurcated pipe 530, while the second water inlet section 522 connects to the bifurcated pipe 530 and passes through the heat dissipation device 300. The first water inlet section 521 is located above the second water inlet section 522 to optimize the water flow path. The portion of the water pipe 520 after passing through the heat dissipation device 300 is defined as the water outlet section 523 and is equipped with a temperature sensor 580 for monitoring the temperature of the cooling water. The control module adjusts the water supply method based on data from the temperature sensor 580: When the temperature of the water outlet section 523 is below the second temperature threshold, the control module turns off the booster pump 570 and the first electric valve 540, and opens the second electric valve 550, allowing water to flow into the heat sink 300 by gravity, achieving natural cooling. When the temperature is above the second temperature threshold, the control module turns on the booster pump 570 and the first electric valve 540, while closing the second electric valve 550, allowing water to flow through the first pipe 531 into the heat sink 300. The booster pump 570 accelerates the water flow, improving cooling efficiency. This design automatically adjusts the water supply flow rate and pressure to meet different heat dissipation requirements, achieving efficient and precise water-cooled heat dissipation management. It is particularly suitable for situations in extremely high temperature environments where air cooling may not be able to effectively reduce the temperature of the electrical cabinet host 200.

[0079] Please refer to Figure 1 In one embodiment, the water storage barrel 510 is connected to an external water source, and the water storage barrel 510 is provided with an exhaust valve 511, which is electrically connected to the control module; when external water is supplied to the water storage barrel 510, the control module controls the exhaust valve 511 to open.

[0080] Specifically, the water storage tank 510 is connected to an external water source and is provided with an exhaust valve 511. When the external water source supplies water to the water storage tank 510, the exhaust valve 511 automatically opens to release the gas inside the water storage tank 510. The design of the exhaust valve 511 effectively balances the pressure inside the water storage tank 510, preventing the negative pressure generated by water entering the water storage tank 510 from affecting the water supply efficiency.

[0081] Please refer to Figure 1 、 Figure 3 and Figure 4In one embodiment, the heat dissipation device 300 includes a first heat dissipation member 310 and a second heat dissipation member 320. The first heat dissipation member 310 is attached to the electrical cabinet host 200, and the second heat dissipation member 320 is attached to the first heat dissipation member 310. The first heat dissipation member 310 is located in the accommodating groove 110, and the second heat dissipation member 320 is located in the air duct 120.

[0082] Specifically, the heat sink 300 is preferably made of heat-conducting aluminum. The first heat sink 310 is attached to the electrical cabinet main unit 200 to directly absorb the heat generated by the electrical cabinet main unit 200. The second heat sink 320 is attached to the first heat sink 310 to further transfer the heat from the first heat sink 310 to the second heat sink 320. The first heat sink 310 is located in the receiving groove 110, and the second heat sink 320 is located in the air duct 120. The first heat sink 310 is installed in the receiving groove 110 to ensure that it can efficiently absorb the heat emitted by the main unit, while the second heat sink 320 is located in the air duct 120 and is used in conjunction with the air cooling device 400 to accelerate heat dissipation. This design utilizes the efficient thermal conductivity of the first heat sink 310 to enable heat to be quickly transferred from the electrical cabinet main unit 200 to the second heat sink 320 and quickly dissipated into the environment through the air cooling or water cooling system, thereby optimizing the heat dissipation path, improving heat dissipation efficiency, effectively reducing the temperature of the electrical cabinet main unit 200, and ensuring long-term stable operation of the equipment.

[0083] Please refer to Figure 4 、 Figure 5 and Figure 6 In one embodiment, the second heat sink 320 includes a heat sink guide (not shown) and a heat sink cover 322. The heat sink guide includes a plurality of first heat conduction plates 3211, each of which is connected to the first heat sink 310. The plurality of first heat conduction plates 3211 are evenly spaced, such that ventilation slots 3212 are defined between adjacent first heat conduction plates 3211. Each ventilation slot 3212 is connected to the air duct 120. The heat sink cover 322 includes a back plate 3222 and a plurality of second heat conduction plates 3221. The back plate 3222 and the plurality of second heat conduction plates 3221 are bonded together. The plurality of second heat conduction plates 3221 are evenly spaced, and each second heat conduction plate 3221 is bonded to one of the first heat conduction plates 3211. The water pipe 520 passes through the back plate 3222 and is bonded to the back plate 3222.

[0084] Specifically, the second heat sink 320 consists of a heat sink guide and a heat sink cover 322. The heat sink includes a plurality of first heat conduction plates 3211. These first heat conduction plates 3211 are connected to the first heat sink 310 and arranged at equal intervals, forming ventilation slots 3212 between adjacent first heat conduction plates 3211. These ventilation slots 3212 communicate with the air duct 120, allowing air flow. The air cooling device 400 drives air flow within the air duct 120, thereby improving heat removal efficiency. The heat sink cover 322 consists of a back plate 3222 and a plurality of second heat conduction plates 3221. The plurality of second heat conduction plates 3221 are arranged at equal intervals and affixed to corresponding first heat conduction plates 3211, i.e., in a one-to-one correspondence, ensuring efficient heat transfer to the second heat conduction plates 3221. The back plate 3222 and the plurality of second heat conduction plates 3221 are affixed to each other.

[0085] In summary, ventilation slots 3212 are connected to air ducts 120, forming a stable air flow channel that quickly removes heat in air-cooling mode, improving heat dissipation. Water pipes 520 pass directly through and adhere to backplate 3222, and are dynamically switched via the control module and temperature and humidity sensor 600, allowing the power distribution cabinet to maintain optimal heat dissipation under varying environmental conditions. The combination of air-cooling device 400 and water-cooling device 500 optimizes heat dissipation efficiency, enabling the power distribution cabinet to adapt to complex operating environments and maintain stable operation over the long term.

[0086] Please refer to Figure 5 and Figure 7 In one embodiment, the water pipe 520 is arranged in the back plate 3222 with multiple U-shaped bends and is arranged at intervals along the horizontal or vertical direction of the back plate 3222 to increase the heat conduction area between the water pipe 520 and the back plate 3222.

[0087] Specifically, when the water pipe 520 passes through the back plate 3222, it is not arranged in a straight line, but is bent in a U-shape multiple times and arranged at intervals along the horizontal or vertical direction of the back plate 3222. This design extends the flow path of the water pipe 520 in the back plate 3222, thereby increasing the contact area between the water pipe 520 and the back plate 3222 and enhancing the efficiency of heat transfer. In the water cooling mode, the cooling water flowing through the water pipe 520 can fully absorb the heat transferred by the heat dissipation cover 322, absorb the heat transferred by the heat dissipation device 300, and improve the heat dissipation efficiency by continuously taking away the heat. At the same time, the layout of the water pipe 520 with multiple U-shaped bends can avoid the problem of insufficient cooling caused by excessively fast water flow speed, ensuring sufficient heat exchange. In addition, this layout method helps to optimize the internal space of the distribution cabinet, making the heat dissipation structure more compact, and taking into account both heat dissipation capacity and overall layout rationality.

[0088] Please refer to Figure 2In one embodiment, the cabinet 100 further defines an air inlet 130 and an air outlet 140 , the air duct 120 is connected to the air inlet 130 and the air outlet 140 , and a plurality of second heat conduction plates 3221 are located between the air inlet 130 and the air outlet 140 . The air cooling device 400 can drive air from the air inlet 130 through the ventilation slots 3212 to be discharged from the air outlet 140 .

[0089] Specifically, the air duct 120 is connected to the air inlet 130 and the air outlet 140, thereby forming a continuous air circulation channel. Multiple second heat conduction plates 3221 are located between the air inlet 130 and the air outlet 140, and are provided with ventilation slots 3212 at equal intervals, allowing air to flow evenly through each heat dissipation component, improving heat exchange efficiency. The air cooling device 400 is installed within the air duct 120. Its function is to drive air in through the air inlet 130, and when passing through the ventilation slots 3212, it fully contacts the second heat conduction plates 3221, removes heat, and is ultimately discharged through the air outlet 140. This design fully utilizes the convection effect of air, allowing heat to be quickly discharged from the cabinet 100 during the heat dissipation process, improving heat dissipation efficiency and reducing the impact of internal heat accumulation on the electrical cabinet main unit 200.

[0090] Please refer to Figure 2 、 Figure 5 and Figure 7 In one embodiment, the air cooling device 400 is disposed near the air inlet 130 .

[0091] Specifically, the air cooling device 400 is positioned near the air inlet 130. This allows the cold air to be driven and accelerated by the air cooling device 400 upon entering the air duct 120, quickly covering the plurality of second heat conduction plates 3221 and improving heat dissipation during the cooling process. Furthermore, installing the air cooling device 400 near the air inlet 130 prevents air from forming stagnant areas within the air duct 120 and enhances air convection, making the heat dissipation process more efficient.

[0092] In one embodiment, a water receiving trough is provided at the bottom of the water outlet section 523 , and the water receiving trough is used to collect the cooling water flowing out of the water outlet section 523 .

[0093] Please refer to Figure 2 In one embodiment, the water cooling device 500 also includes a third electric valve 560, which is connected to the water outlet section 523, the control module is electrically connected to the third electric valve 560, and the water outlet section 523 is connected to the water storage tank 510; when cooling water needs to be discharged from the water outlet section 523, the control module controls the third electric valve 560 to open to discharge the cooling water.

[0094] Specifically, the third electric valve 560 is used to control the discharge of cooling water to achieve more flexible water management. The third electric valve 560 is connected to the water outlet section 523 and is intelligently regulated by the control module. At the same time, the water outlet section 523 is connected to the water storage tank 510, allowing the cooling water to flow back to the water storage tank 510 for recycling.
