Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and in particular discloses an intelligent liquid-cooled moisture-proof power distribution cabinet. Background Art

[0002] The power distribution cabinet (PDC) is the final stage of the power distribution system, housing numerous electrical components. During high-power load operation, it easily generates significant heat, necessitating timely internal cooling. Existing PDC cooling methods primarily include natural air cooling, forced air cooling, and liquid cooling. Natural and forced air cooling require vents in the cabinet to facilitate air flow. Liquid-cooled PDCs also typically require vents to reduce heat dissipation energy consumption during normal operation. These vents allow for natural air cooling of the electrical components during normal operation, with the liquid cooling system activated only when the internal temperature becomes excessively high.

[0003] For example, the utility model patent with application number 201921869488.6 discloses a switch cabinet with a heat dissipation structure, including a switch cabinet and a ventilation box, a small through-hole is provided on the component mounting plate, a heat-absorbing cotton is provided on the rear side of the component mounting plate, a circulating water pipe is provided on the rear side of the heat-absorbing cotton, a ventilation fan is provided on the inside of the ventilation box, an ion fan is provided on the inside of the switch cabinet, a heat dissipation hole is provided on the upper end of the switch cabinet, a waterproof plate is provided on the bottom end of the ventilation box, and a vent is provided on the outside of the ventilation box. This patent adopts a typical forced liquid cooling method. The flow of low-temperature liquid inside the circulating water pipe can force the interior of the cabinet to absorb heat and cool it. At the same time, heat dissipation holes are opened on the cabinet, and a fan is used to realize the flow between the inside of the cabinet and the outside world to achieve air cooling. However, in some southern regions with high humidity or during the rainy season, moisture in the air can easily enter the cabinet through the heat dissipation holes, causing short circuits in internal electrical components or corrosion of metal parts. The existing solution is to place desiccant inside the heat dissipation holes to absorb and dry the air entering the cabinet. However, these desiccants not only cause poor air circulation through the heat dissipation holes, but also require regular replacement, making them more cumbersome to use. Therefore, to address the above-mentioned shortcomings of existing liquid-cooled and heat-dissipating combined power distribution cabinets, this application proposes an intelligent liquid-cooled, moisture-proof power distribution cabinet that effectively solves these technical problems. Summary of the Invention

[0006] As a further arrangement of the above scheme, the blowing pipe and the exhaust fan device are connected through a movable joint pipe, and the exhaust fan device includes a special-shaped pipe, an impeller shaft is provided in the special-shaped pipe, and a fan impeller and a driven wheel are provided at both ends of the impeller shaft, and the driven wheel is connected to the driving wheel located in the special-shaped pipe through a transmission belt, and the outer end shaft of the driving wheel is connected to the driving motor through a curved joint rod, and a connecting rod is rotatably provided on the curved joint rod, and the end of the connecting rod is connected to the blowing pipe.

[0007] As a further configuration of the above solution, the lower end of the heat exchange box is connected to an S-shaped liquid sealing pipe, and the end of the liquid sealing pipe is connected to a drainage pipe extending out of the cabinet.

[0008] As a further arrangement of the above scheme, the driving mechanism includes a movable plate that fits and covers the inner side of the heat dissipation hole, and a through hole aligned with the heat dissipation hole is provided on the movable plate, a vertical slide rail that is slidably connected to the movable plate is provided on the inner wall of the cabinet, and a spring is provided between the bottom wall of the cabinet and the movable plate, a wire pulley is provided at the bottom of the cabinet, and a pull rope is provided on the guide wheel, one end of the pull rope is connected to the movable plate, and the other end is connected to a magnetic slider that is slidably set on the bottom wall of the cabinet, and an electromagnet for adsorbing the magnetic slider is fixed to the bottom of the cabinet.

[0009] As a further arrangement of the above scheme, heat dissipation holes are provided on both the left and right sides of the cabinet, and the magnetic sliders in the driving mechanism corresponding to the heat dissipation holes on both sides are respectively located on both sides of the electromagnet and aligned with the electromagnet.

[0010] As a further configuration of the above scheme, the cooling source device includes a cooling water tank with a built-in semiconductor refrigerator, the cooling water tank is provided with a circulating water pump, and both ends of the heat exchange tube are respectively connected to the cooling water tank and the circulating water pump.

[0011] As a further configuration of the above solution, a plurality of heat exchange fins are arranged in a row, and the heat exchange tubes are arranged to pass through the heat exchange fins in a circuitous manner for multiple times.

[0012] As a further configuration of the above solution, an operating port is provided on the front side of the cabinet, a cabinet door is rotatably connected to the operating port, and the controller is arranged on the front side of the cabinet next to the operating port.

[0013] As a further configuration of the above solution, the controller is provided with a display and a forced cooling and dehumidification button.

[0014] The intelligent liquid-cooled moisture-proof distribution cabinet disclosed by the present invention is configured to be operated in hot and humid weather. When the temperature sensor and humidity sensor detect that the internal temperature and humidity exceed the set threshold, the controller will actively start the corresponding cooling and dehumidification program. After the cooling and dehumidification program is started, the driving mechanism is first controlled to close all the heat dissipation holes to isolate the interior of the cabinet from the external environment. Next, the cold heat exchange device, the cold source device and the exhaust fan device are started. The cold source device continuously sends low-temperature water into the cold heat exchange device. Then, the heat generated by the electrical components on the horizontal row is absorbed by the heat transfer effect of the heat exchange fins and the heat-conducting metal plates. At the same time, the hot and humid air inside the cabinet is drawn into the cold heat exchange device under the action of the exhaust fan device, so that the water vapor in the air is cooled and liquefied on the heat exchange tubes and heat exchange fins. The dry and cooled low-temperature air is then discharged from the blow pipe and blown toward the electrical components on the horizontal row again, realizing rapid cooling and air drying inside the cabinet. After the internal temperature and humidity are reduced to the set value, the controller closes the corresponding program again.

[0015] In dry and hot weather, only when the temperature inside the cabinet exceeds the set threshold will the controller actively start the forced cooling program. At this time, the heat dissipation holes are still kept open, and the cold heat exchange device and the cold source device are started at the same time. The heat exchange fins and the heat-conducting metal plates are cooled by the low-temperature water flowing inside the cold heat exchange device, and the electrical components are cooled by the heat absorption effect of the heat exchange fins and the heat-conducting metal plates. At the same time, rapid cooling is achieved in conjunction with the flow of external air.

[0016] In normal weather, when the temperature and humidity inside the cabinet exceed the set threshold, the cabinet can achieve internal natural air cooling through the air exchange between the heat dissipation holes and the outside world. There is no need to start the active heat dissipation program, which reduces the energy consumption of the distribution cabinet during long-term operation.

[0017] Compared with the prior art, the present invention has the following beneficial effects: During operation, the intelligent liquid-cooled moisture-proof distribution cabinet disclosed in the present invention can detect the internal temperature and humidity in real time through sensors, and then automatically start the corresponding control program according to the detection results to realize different heat dissipation modes and dehumidification operations inside the distribution cabinet, so that it can operate stably in various environments. It has a high degree of intelligence and good heat dissipation and moisture-proof performance.

[0018] Through the coordinated action between the cold heat exchange device, the cold source device and the exhaust fan device, the present invention can not only actively realize the active liquid cooling of the interior of the distribution cabinet, but also can actively liquefy and remove moisture in the air in hot and humid weather. There is no need to set a desiccant to dehumidify the distribution cabinet, and at the same time will not affect the natural air cooling effect of the heat dissipation holes, and has a better use effect.

[0019] The present invention further implements a linkage design between the exhaust fan device and the air blowing pipe, so that when the exhaust fan device discharges the cold air after drying and cooling from the air blowing pipe, the cold air discharged from the air blowing hole can be blown toward the electrical components in the horizontal row at a certain swing angle, so that the electrical components close to and far away from the air blowing pipe can be evenly affected by the cold air flow, thereby achieving rapid and uniform cooling.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings 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 in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. Figures 1 to 7 , and describes the application in detail with reference to embodiments. Example 1

[0024] Example 1 discloses an intelligent liquid-cooled moisture-proof power distribution cabinet. Figure 1 and attached Figure 2 , including a cabinet body 1, a top cover 2 and a base 3. The top cover 2 is arranged on the top of the cabinet body 1, and extends out of the four sides of the cabinet body 1 by a certain distance, so that it has a certain rain-proof effect. The base 3 is arranged at the bottom of the cabinet body 1, so that the entire distribution cabinet is at a certain height from the ground after installation, and has a certain flood-proof effect.

[0025] The front side of the cabinet 1 features an access panel, to which a cabinet door 4 is hingedly connected. A controller 5 is also located adjacent to the access panel. A temperature sensor 18 and a humidity sensor 19 are located within the cabinet 1 and are electrically connected to the controller 5. The controller 4 includes a display and buttons, which display the real-time temperature and humidity inside the cabinet 1 and automatically activate the corresponding cooling program based on set thresholds. The button is a forced cooling and dehumidification button, which can be manually pressed by the user to execute the corresponding control command.

[0026] Reference Attachment Figure 3 and attached Figure 4 Corresponding heat dissipation holes 101 are provided on both the left and right sides of the cabinet 1. When the heat dissipation holes 101 are open, they allow external air to enter and carry away heat through convection, achieving a certain heat dissipation and cooling effect. A pair of vertical slide rails 102 are fixed to the inner wall of the cabinet 1 on both sides of the heat dissipation holes 101. A movable plate 6 that fits and covers the heat dissipation holes 101 is slidably provided in the vertical slide rails 102. The movable plate 6 is provided with a through hole aligned with each heat dissipation hole 101. When the through hole is aligned with the heat dissipation hole 101, it does not affect the natural heat dissipation effect inside the cabinet 1.

[0027] A spring 7 connected to the bottom wall of the cabinet 1 is provided at the lower end of the movable plate 6. The supporting force of the spring 7 allows the through-holes on the surface of the movable plate 6 to be aligned with the heat dissipation holes 101 when not subject to external forces. A wire pulley 8 is provided at each of the left and right ends of the bottom wall of the cabinet 1. A pulley 8 is provided on the wire pulley 8. One end of the pulley 9 is connected to the lower end of the corresponding movable plate 6, and the other end is connected to a magnetic slider 10 that is slidably arranged on the bottom wall of the cabinet 1. Finally, an electromagnet 11 is fixedly installed on the bottom wall of the cabinet 1 between the two magnetic sliders 10, and the magnetic poles at both ends of the electromagnet 11 are respectively aligned with the two magnetic sliders 10, so that when current is passed through the electromagnet 11, the magnetic sliders 10 on both sides can be synchronously attracted and moved toward the middle. Then, under the action of the pull rope 9, the movable plates 6 on both sides are pulled downward along the vertical slide rails 102, so that the through-holes are misaligned with the heat dissipation holes 101, thereby achieving active closure of the heat dissipation holes 101.

[0028] Reference Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 A heat-conducting metal plate 12 is fixedly mounted inside the cabinet 1. Multiple horizontal rows 13 are spaced apart vertically on the front surface of the vertical section of the heat-conducting metal plate 12, allowing the corresponding electrical components to be neatly installed on the rows 13. This ensures neat wiring and facilitates subsequent repair and maintenance. A liquid-cooled heat exchanger 14 is installed at the center of the back of the heat-conducting metal plate 12. A cooling source 15 is connected to the lower end of the liquid-cooled heat exchanger 14.

[0029] Reference Attachment Figure 5 The liquid-cooled heat exchange device 14 is located in a heat exchange box 141 on the back of the heat-conducting metal plate 12. A row of heat exchange fins 142 are installed in the heat exchange box 141 and connected to the back of the heat-conducting metal plate 12. The heat exchange fins 142 are arranged horizontally. Heat exchange tubes 143 are installed in the heat exchange box 141, winding through the heat exchange fins 142 multiple times. Both ends of the heat exchange tubes 143 extend out of the bottom surface of the heat exchange box 141 and connect to the cooling source device 15. The specific cooling source device 15 includes a cooling water tank 151 with a built-in semiconductor refrigerator. A circulating water pump 152 is connected to the cooling water tank 151. The two ends of the heat exchange tube 143 are respectively connected to the cooling water tank 151 and the circulating water pump 152. The low-temperature water is continuously injected into the heat exchange tube 143 through the circulating water pump 152, and then the heat is absorbed by the heat-conducting metal plate 12 through the heat-exchange fins 142. The heat generated by the electrical components on the horizontal row 13 is fully absorbed by the heat-conducting metal plate 12, thereby achieving the effect of active heat dissipation and cooling.

[0030] The liquid-cooled heat exchanger 14 also includes an air inlet pipe 144 and an air outlet pipe 145, respectively connected to the left and right ends of the heat exchanger box 141. The end of the air inlet pipe 144 passes through the heat-conducting metal plate 12 and extends to the front end of the inner cavity of the cabinet 1. The end of the air outlet pipe 145 is equipped with an exhaust fan device 17. The end of the exhaust fan device 17 is connected to a blow pipe 146 located vertically on the front side of the heat-conducting metal plate 12 through an elbow 149. The blow pipe 146 is also equipped with a plurality of air holes spaced apart and facing the front side of the heat-conducting metal plate 12. Finally, an S-shaped liquid seal pipe 147 is connected to the bottom of the heat exchanger box 141, and the lower end of the liquid seal pipe 147 is connected to a drain pipe 148 extending from the cabinet 1.

[0031] The intelligent liquid-cooled moisture-proof distribution cabinet disclosed in this embodiment 1 has three operating modes. Under normal temperature conditions, the liquid-cooled heat exchange device 14, the cold supply source device 15 and the exhaust fan device 17 are all inoperative, and the heat dissipation holes 101 are in an open state. At this time, the natural wind from the external environment is used to dissipate heat naturally inside. Under high temperature and dry conditions, the liquid-cooled heat exchange device 14 and the cold supply source device 15 are started, and the low-temperature water in the cold supply source device 15 is continuously flowed along the heat exchange tube 143. The heat generated by the electrical components is then absorbed through the heat transfer effect of the heat exchange fins 142 and the heat-conducting metal plate 12. At the same time, the heat dissipation holes 101 are in an open state to use natural wind to assist in heat dissipation. In a hot and humid environment, current is first passed through the electromagnet 11, so that the movable plate 6 actively closes the heat dissipation hole 101, isolating the interior of the cabinet 1 from the outside world, and then the liquid-cooled heat exchange device 14, the cold source device 15 and the exhaust fan device 17 are started. While the liquid-cooled heat exchange device 14 transfers and absorbs the heat generated by the electrical components, it can also draw the hot and humid air inside the cabinet 1 into the heat exchange box 141 through the air inlet pipe 144 to directly exchange heat with the liquid-cooled heat exchange device 14. Secondly, the water vapor in the air can be quickly liquefied into water droplets when in direct contact with the liquid-cooled heat exchange device 14, and finally gather at the bottom of the heat exchange box 141 and be discharged through the drain pipe 148. Thirdly, the gas that has been liquefied, dried and cooled can be discharged from a row of blowing holes on the blowing pipe 146, and then blown directly onto the surface of the electrical components to accelerate the cooling of the electrical components. Example 2

[0032] Example 2 discloses an intelligent liquid-cooled moisture-proof distribution cabinet that is further improved based on the technical solution in Example 1. The similarities between it and Example 1 will not be described again.

[0033] Reference Attachment Figure 6 and attached Figure 7The exhaust fan device 17 in this embodiment 2 includes a special-shaped pipe 171 whose two ends are respectively connected to the air inlet pipe 144 and the air outlet pipe 145. A rotating bracket 172 is provided in the special-shaped pipe 171, and an impeller shaft 173 is rotatably connected to the rotating bracket 172. Then, a fan impeller 174 and a driven wheel 175 are respectively provided at both ends of the impeller shaft 173. A driving wheel 176 is provided in the special-shaped pipe 171 above the driven wheel 175, and a transmission belt 177 is provided between the driving wheel 175 and the driven wheel 175.

[0034] The outer end of the driving wheel 175 extending from the irregularly shaped pipe 171 is connected to a curved rod 178, and the other end of the curved rod 178 is connected to a drive motor 179. When driven by the drive motor 179, the curved rod 178 drives the driving wheel 175 to rotate, which in turn, driven by the drive belt 177, rotates the fan impeller 174, thereby exhausting air from the interior of the heat exchanger 141. A connecting rod 20 is rotatably connected to the curved rod 178. The elbow 149 at the end of the irregularly shaped pipe 171 is replaced with a flexible joint pipe with a telescopic effect. Finally, the end of the connecting rod 20 is movably connected to the end of the air blowing pipe 146.

[0035] Through the design of the above-mentioned scheme, this embodiment 2 can, during the operation of the exhaust fan device 17, drive the adjustment of the direction of the blowing hole on the blowing pipe 146 through the action of the curved rod 178 and the connecting rod 20, so that the gas discharged from the blowing hole can be blown toward the electrical components on the horizontal row 13 at a certain swing angle, so that the electrical components close to and far away from the blowing pipe 146 can be evenly affected by the cold air flow, thereby achieving rapid and uniform cooling.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
