Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly gas cabinet technology, specifically an intelligent heat dissipation and gas leakage compensation system for an environmentally friendly gas cabinet. Background Technology

[0002] Environmentally friendly gas switchgear (environmentally friendly gas-insulated ring main unit) is a medium-voltage power distribution equipment that uses environmentally friendly gas instead of traditional SF6 (sulfur hexafluoride) as the insulating medium. It is widely used in power grid distribution, industry, transportation, data centers and other fields.

[0003] However, the heat dissipation performance of the environmentally friendly gas (such as nitrogen) in the existing environmentally friendly gas cabinet is relatively poor, which makes the temperature of the gas box easy to rise during operation, making the electric field easy to become unstable.

[0004] The current method of heat dissipation is to install water-cooled heat exchangers inside the environmentally friendly gas cabinet. However, installing heat exchangers inside the environmentally friendly gas cabinet can easily change the internal structural layout of the cabinet and occupy internal space. In addition, the environmentally friendly gas filling the cabinet is prone to partial leakage after long-term use, which leads to a decrease in internal pressure, reduces the insulation effect, and increases the possibility of discharge between charged parts inside the cabinet. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent heat dissipation and gas leakage compensation system for an environmentally friendly gas cabinet, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent heat dissipation and gas leakage compensation system for an environmentally friendly gas cabinet, detachably installed on the back panel of the gas tank of the environmentally friendly gas cabinet, including an integrated backpack.

The outlet end of the water-cooled aluminum plate is connected to the inlet end of the water storage box.

[0010] The above-mentioned intelligent heat dissipation and gas leakage compensation system for environmentally friendly gas cabinet: the wind power heat dissipation unit includes: a heat dissipation aluminum plate for heat dissipation of water-cooled aluminum plate and a fan mounting plate fixed in the heat dissipation chamber, wherein at least one heat dissipation fan is installed on the fan mounting plate.

[0011] The above-mentioned intelligent heat dissipation and gas leakage compensation system for environmentally friendly gas cabinet: the gas replenishment structure is installed in the gas maintenance chamber and includes: an air pump and a gas storage tank with an integrated pressure gauge.

[0012] The above-mentioned intelligent heat dissipation and gas leakage compensation system for environmentally friendly gas cabinet also includes a control circuit for connecting the heat dissipation structure and the gas replenishment structure.

[0014] The semiconductor cooling chip has excellent thermal conductivity. When powered on, it can efficiently transfer heat from the back panel of the environmentally friendly gas cabinet to the water-cooled aluminum plate, rapidly cooling the inside of the cabinet. The water circulation within the water-cooled aluminum plate carries away the heat, achieving water cooling. Simultaneously, the included fan-powered cooling unit can provide air cooling during operation, further improving heat dissipation efficiency.

The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0024] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0025] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0026] Please see Figures 1-3In this embodiment of the utility model, an intelligent heat dissipation and gas leakage compensation system for an environmentally friendly gas cabinet is detachably installed on the back panel of the gas tank 2 of the environmentally friendly gas cabinet. It includes an integrated backpack 1, which comprises a housing 101 with multiple chambers. Each chamber is equipped with a heat dissipation structure and a gas replenishment structure. The gas replenishment structure is connected to a gas tank replenishment valve 120 on the gas tank 2 of the environmentally friendly gas cabinet. The heat dissipation structure includes a semiconductor cooling chip 102 and a water-cooled aluminum plate 103. Both sides of the semiconductor cooling chip 102 are in contact with the back panel of the gas tank 2 and the water-cooled aluminum plate 103, respectively. A wind-powered heat dissipation unit is provided on the side of the water-cooled aluminum plate 103 away from the semiconductor cooling chip 102.

[0027] In this embodiment, the integrated backpack 1, which is equipped with a heat dissipation structure and a gas replenishment structure, is modularly designed. It is easy to assemble with the environmentally friendly gas cabinet 2, and will not cause significant changes to the main structure of the environmentally friendly gas cabinet 2, making it convenient to use.

[0028] Secondly, the semiconductor cooling chip 102 has excellent thermal conductivity. When powered on, it can efficiently transfer the heat from the back panel of the environmentally friendly gas cabinet 2 to the water-cooled aluminum plate 103, quickly cooling the inside of the environmentally friendly gas cabinet 2. The water circulation inside the water-cooled aluminum plate 103 carries away the heat, realizing the water cooling function. At the same time, the set fan cooling unit can perform air cooling when working, further improving the heat dissipation efficiency. The tight combination of the semiconductor cooling chip 102 and the water-cooled aluminum plate 103 ensures the effective and rapid transfer of heat. The air cooling and water cooling work together to ensure stable control of the internal temperature of the environmentally friendly gas cabinet 2, effectively solving the problem of poor heat dissipation performance of environmentally friendly gases (such as nitrogen).

[0029] Meanwhile, the gas replenishment structure set in this embodiment can be used to replenish the gas in the gas tank 2 of the environmentally friendly gas cabinet, so as to realize the automatic compensation of nitrogen in the gas tank 2 of the environmentally friendly gas cabinet.

[0030] Furthermore, the multiple chambers formed within the enclosure 101 are a control chamber, a heat dissipation chamber, a coolant maintenance chamber, and a gas maintenance chamber. A controller chamber cover 115, a heat dissipation chamber cover 114, a coolant maintenance chamber cover 111, and a gas maintenance chamber cover 110 are respectively installed on the control chamber, heat dissipation chamber, coolant maintenance chamber, and gas maintenance chamber. It should be noted that the connection between the controller chamber cover 115, heat dissipation chamber cover 114, coolant maintenance chamber cover 111, and gas maintenance chamber cover 110 and the enclosure 101 can be a hinged connection or directly bolted. The choice can be made according to actual needs, and this embodiment does not impose specific limitations on this.

[0031] Further, please refer to Figures 3-5The water-cooled aluminum plate 103 is installed in the heat dissipation chamber and is connected to the circulating heat exchange unit located in the coolant maintenance chamber. The circulating heat exchange unit includes: a water storage box 105 storing coolant and a water pump 104 that is connected to the inlet end of the water-cooled aluminum plate 103 and the outlet end of the water storage box 105 respectively. The outlet end of the water-cooled aluminum plate 103 is connected to the inlet end of the water storage box 105.

[0032] The water pump 104 is connected to the water-cooled aluminum plate 103 and the water storage box 105 through water pipes, and the water-cooled aluminum plate 103 and the water storage box 105 are also connected by water pipes, thus forming a circulation path. When the water pump 104 is activated, the coolant in the water-cooled aluminum plate 103 flows, thereby achieving water cooling heat dissipation.

[0033] Please see Figure 3 The wind-powered heat dissipation unit includes a heat dissipation aluminum plate 118 for dissipating heat from the water-cooled aluminum plate 103 and a fan mounting plate 106 fixed in the heat dissipation chamber. At least one cooling fan 117 is mounted on the fan mounting plate 106.

[0034] In order to blow out hot air and at the same time block dust, the heat dissipation chamber cover 114 has a notch, and a heat dissipation filter 113 is installed at the notch.

[0035] When the cooling fan 117 is working, it absorbs the heat from the heat dissipation aluminum plate 118 and blows it towards the filter screen 113, blowing out the hot air. In conjunction with the heat dissipation aluminum plate 118, it transfers the heat into the air, achieving air cooling.

[0036] Please see Figure 3 and Figure 6 The gas replenishment structure is installed in the gas maintenance chamber and includes a gas pump 107 and a gas storage tank 108 with an integrated pressure gauge 109. The inlet and outlet of the gas pump 107 are respectively connected to the gas storage tank 108 and the gas box replenishment valve 120.

[0037] The gas maintenance chamber cover 110 is equipped with a pressure gauge observation cover 112 so that staff can check the reading of the pressure gauge 109. The pressure gauge 109 is used to monitor the gas pressure in the gas storage tank 108 so that it can be replaced in time when there is no gas in the gas storage tank 108.

[0038] The environmentally friendly gas cabinet 2 has a pressure gauge inside, which has a monitoring function. When the gas in the environmentally friendly gas cabinet 2 decreases, the pressure gauge transmits a signal to the controller 116. The controller controls the gas pump 107 to start, so as to replenish the gas in the gas storage tank 108 into the environmentally friendly gas cabinet 2, so that the pressure of the environmentally friendly gas cabinet 2 reaches the standard.

[0039] It should also be noted that the intelligent heat dissipation and gas leakage compensation system for the environmentally friendly gas cabinet also includes a control circuit 119 for connecting the heat dissipation structure and the gas replenishment structure. The control circuit 119 is located in the control room and is connected to a controller 116. The controller 116 and the control circuit 119 are used to control the operation of the heat dissipation structure and the gas replenishment structure. This is a conventional control method, so it will not be described in detail in this embodiment.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
