An integrated heat dissipation structure of a ring network box

Abstract

The present invention relates to the field of electrical equipment technology, and in particular to an integrated heat dissipation structure for a ring main unit (RMU) box, comprising a shell, a slide, and a heat pipe with a variable volume. The slide is provided with a phase-change heat storage material, one end of the heat pipe is hinged to the slide, and the other end of the heat pipe extends into the shell. In a first state, one end of the heat pipe inside the shell is located below the other end. In a second state, one end of the heat pipe inside the shell is located above the other end. The volume of the heat pipe in the first state is smaller than the volume of the heat pipe in the second state. In the first state, the phase-change heat storage material in the slide absorbs heat from the shell and the outside world, and the temperature inside the slide approaches the temperature inside the shell or even exceeds the temperature inside the shell. In the second state, if the temperature inside the shell is lower than that of the slide, the slide transfers heat to the inside of the shell, allowing the electronic components inside the RMG box to operate normally.

Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and in particular to an integrated heat dissipation structure of a ring network box. Background Art

[0002] In modern power systems, ring main units (RMUs) serve as critical equipment for power distribution and control, widely used in urban power grids, industrial power supplies, and other fields. Many of these units are installed outdoors, shouldering the important task of ensuring stable power transmission and distribution. However, the complex and ever-changing outdoor environment poses significant challenges to the performance and reliability of RMUs.

[0003] Compared to indoor cabinets, heat dissipation in outdoor cabinets presents more complex challenges. Especially in extreme regions like deserts and plateaus, ambient temperatures can soar to high temperatures during the day under the scorching sun, then plummet rapidly at night, with temperature differences reaching tens of degrees Celsius. Electronic components within the ring main box, such as transformers, switches, and fuses, are extremely sensitive to temperature. Thermal expansion and contraction can loosen component pins, solder joints, and other connections, leading to poor contact, electrical failure, and even component damage in severe cases.

[0004] Existing heat dissipation structures for ring mainframe enclosures are mostly traditional, such as simple ventilation holes or conventional cooling fans. These cooling methods are difficult to cope with such drastic temperature fluctuations and cannot effectively balance the temperature inside the enclosure. They are inefficient during high-temperature periods and difficult to prevent excessive heat loss during low-temperature periods. Summary of the Invention

[0035] like Figures 1 to 11 As shown, an embodiment of the present invention provides an integrated heat dissipation structure of a ring network box, including a temperature control mechanism for dissipating heat to the ring network box 121, the temperature control mechanism including a shell 101, a fan 119, a slide 103 and a heat pipe with variable volume, the ring network box 121 is arranged inside the shell 101, the shell 101 is provided with a vertically arranged vent 102, the slide 103 is slidably arranged outside the shell 101 along the vertical direction, a phase change heat storage material is provided in the slide 103, the heat pipe is slidably arranged on the vent 102, one end of the heat pipe is hinged to the slide 103, and the other end of the heat pipe extends into the shell 101, the interior of the heat pipe is filled with a cooling medium, and the cooling medium can be volatile liquids such as alcohol, liquid ammonia and Freon, and the heat pipe is used to exchange heat between the slide 103 and the shell 101.

[0036] The temperature control mechanism has a first state and a second state. During the day, the temperature control mechanism is in the first state, with the vent 102 connecting the inside and outside of the housing 101, and one end of the heat pipe inside the housing 101 is located below the other end. At night, the temperature control mechanism is in the second state, with the inside and outside of the housing 101 isolated, and one end of the heat pipe inside the housing 101 is located above the other end. The volume of the heat pipe in the first state is smaller than that in the second state. A light sensor is provided on the housing 101, which can switch the temperature control mechanism between the first and second states according to changes in ambient light intensity.

[0037] Phase change heat storage material is set in the skateboard 103. In the first state, part of the heat in the shell 101 will be transferred to the skateboard 103 through the heat pipe, and then absorbed by the phase change heat storage material in the skateboard 103. At the same time, the skateboard 103 will also absorb the heat outside the shell 101 through the phase change heat storage material. The temperature inside the skateboard 103 will be close to the temperature inside the shell 101 or even higher than the shell 101; in the second state, the temperature of the phase change heat storage material in the skateboard 103 is higher than the external environment of the shell 101, and it will start to dissipate heat and cool down. At this time, the volume of the heat pipe is larger than its internal volume in the first state, and the internal pressure is relatively small. The boiling point of the cooling medium is lowered, and the heat of the skateboard 103 is more easily transferred to the inside of the shell 101 through the heat pipe, so that the temperature difference of the environment in which the ring network box 121 is located is small, and the electronic components inside the ring network box 121 can operate normally.

[0038] In this embodiment, the heat pipe is a telescopic pipe with sealed ends. The heat pipe includes a first pipe 104 and a second pipe 105. One end of the first pipe 104 is sleeved within the second pipe 105, and the first and second pipes 104 and 105 are slidably connected. A sealing ring is provided on the inner wall of the second pipe 105, which is slidably connected to the first pipe 104. The first and second pipes 104 and 105 are internally connected and slidably sealed by the sealing ring. When the length of the heat pipe changes, its internal volume increases.

[0039] In this embodiment, a bellows 106 is sleeved on the first tube 104 and the second tube 105. The bellows 106 can expand and contract along the axial direction of the first tube 104. The two ends of the bellows 106 are fixedly connected to the circumferential surface of the first tube 104 and the circumferential surface of the second tube 105 respectively. The bellows 106 can seal the connection position of the first tube 104 and the second tube 105 to prevent the cooling medium from leaking from the sliding sealing position of the first tube 104 and the second tube 105 and causing damage to the electronic components in the ring network box 121.

[0040] In this embodiment, a side of the slide plate 103 close to the shell 101 is provided with a curved surface, and an end of the first tube 104 away from the second tube 105 is provided with a thermal cap 107. The side of the thermal cap 107 away from the first tube 104 is a spherical surface, and the spherical surface of the thermal cap 107 is slidably connected to the curved surface of the shell 101. When the first tube 104 rotates on the shell 101, the thermal cap 107 can increase the contact area with the shell 101 through the cooperation between the spherical surface and the curved surface of the shell 101, so that the heat conduction efficiency of the shell 101 and the first tube 104 is higher.

[0041] In this embodiment, a groove 108 is provided on the side wall of the vent 102, and a square frame 109 is provided in the groove 108 for sliding along the vertical direction. The sliding distance of the square frame 109 is smaller than the sliding distance of the slide 103. The highest sliding position of the slide 103 and the square frame 109 is set as the upper pole, and the lowest sliding position of the slide 103 and the frame 109 is set as the lower pole. The upper pole and the lower pole of the frame 109 are located between the upper pole and the lower pole of the slide 103 in the vertical direction. When the temperature control mechanism is in the first state, the slide 103 and the frame 109 are both at the upper extreme point. When the temperature control mechanism is in the second state, the slide 103 and the frame 109 are at the lower extreme point. The vertical distance between the upper extreme point of the frame 109 and the upper extreme point of the slide 103 is smaller than the vertical distance between the lower extreme point of the frame 109 and the lower extreme point of the slide 103. When the frame 109 and the slide 103 are at the upper extreme point, the heat pipe is also at the upper extreme point. When the frame 109 and the slide 103 are at the lower extreme point, the heat pipe is also at the lower extreme point. When the heat pipe is at the upper extreme point The length of the heat pipe is less than the length of the heat pipe at the lower extreme point, that is, the volume of the heat pipe in the first state is greater than the volume in the second state. The pressure inside the heat pipe decreases with the increase of volume, and the vaporization temperature of the cooling medium decreases with the increase of pressure. Compared with the existing technology, the heat pipe with variable volume can better transfer the temperature of the phase change heat storage material in the slide 103 to the shell 101, and at the same time, the cooling medium in the heat pipe in the daytime environment evaporates more slowly, and can continuously transfer the heat in the shell 101 to the slide 103. The second tube 105 is hinged to the frame 109, and the first tube 104 is hinged to the slide 103. The hinge axis of the first tube 104 and the slide 103 is parallel to the hinge axis of the second tube 105 and the frame 109. When the slide 103 and the frame 109 slide relative to each other in the vertical direction, the first tube 104 can rotate on the slide 103, and the second tube 105 can rotate relative to the frame 109. A plurality of heat-conducting tubes are provided in the vertical direction in the frame 109. The plurality of heat-conducting tubes are arranged in the vertical direction, which can better realize heat transfer between the slide 103 and the inside of the shell 101.

[0042] In this embodiment, an upper heat insulation plate 110 and a side heat insulation plate 111 are provided on the shell 101. The upper heat insulation plate 110 is located at the top of the shell 101. The side heat insulation plate 111 is covered on the outer side of the shell 101 and is located between the slide plate 103 and the shell 101. The slide plate 103 is slidably connected to the side heat insulation plate 111. The side heat insulation plate 111 can effectively reduce the heat exchange between the inside and outside of the shell 101 and play a role in heat preservation. A through groove 112 is opened on the side heat insulation plate 111, and the vent 102 is connected to the through groove 112. The through groove 112 is vertically The direction is consistent with the air outlet, which can ensure that the hot air above the shell 101 is discharged smoothly, and the heat pipe is slidably set in the through groove 112; an air outlet groove 113 is opened on the slide plate 103, and the through groove 112 is divided into two parts, upper and lower parts, the through groove 112 in the upper part can be connected with the air outlet groove 113, and the through groove 112 in the lower part is staggered in the vertical direction of the air outlet groove 113. When the temperature control mechanism is in the first state, the air outlet groove 113 is connected with the through groove 112, and in the second state, the air outlet groove 113 is separated from the through groove 112.

[0043] In this embodiment, a protective cover 114 that extends vertically is provided on the housing 101. The protective cover 114 is located above the slide 103, and its two ends are connected to the housing 101 and the slide 103, respectively. A sealing plate is provided on the inner side of the protective cover 114 to isolate the interior of the protective cover 114 from the outside world. When the slide 103 moves to the lower extreme point, the slide 103 blocks the lower through-slot 112, while the upper through-slot 112 is blocked by the protective cover 114, thereby reducing heat loss inside the housing 101 in the second state. At the same time, the protective cover 114 can also provide a certain degree of protection for the ring main box 121 in harsh environments.

[0044] In this embodiment, a threaded rod 115 extending in the vertical direction is provided inside the shell 101. The threaded rod 115 is rotatably connected to the shell 101 around its own axis. A transmission plate 116 is threadedly connected to the threaded rod 115. The transmission plate 116 passes through the shell 101 and is connected to the slide 103. The transmission plate 116 is slidably connected to the shell 101 along the vertical direction. A motor 117 is provided in the shell 101. The motor 117 is used to drive the threaded rod 115 to rotate, thereby causing the transmission plate 116 and the threaded rod 115 to drive the slide 103 to move up and down under the threaded cooperation. A sliding groove is provided on the side wall of the shell 101, and the transmission plate 116 is slidably arranged in the sliding groove along the vertical direction; a reducer 118 is provided at the output end of the motor 117, and the output end of the motor 117 is connected to the input end of the reducer 118, and the output end of the reducer 118 is connected to the threaded rod 115. The motor 117 drives the threaded rod 115 to rotate slowly and at a uniform speed through the reducer 118.

[0045] In this embodiment, a fan 119 is provided inside the shell 101. When the temperature control mechanism is in the first state, the fan 119 can exchange the gas inside and outside the shell 101 through the vent 102. The fan 119 is arranged on the inner bottom wall of the shell 101, and the gas outside the shell 101 is drawn to the bottom of the shell 101 through the vent 102, so that the high-temperature gas in the shell 101 can be discharged from the shell 101 faster.

[0046] In this embodiment, a door 120 is provided on one side of the housing 101 to facilitate maintenance of the ring main box 121 within the housing 101. The three sides of the housing 101 not provided with the door 120 are each provided with multiple vents 102. Each vent 102 is provided with a square frame 109, and each square frame 109 is provided with multiple heat pipes. These multiple heat pipes ensure a more stable temperature within the housing 101. The slide 103 is U-shaped, with each side of the slide 103 slidingly connected to a side of the housing 101. The sealing plate is a rectangular frame, with three sides of the sealing plate slidingly connected to the slide 103, and the other side of the sealing plate slidingly connected to the housing 101.

[0047] The working principle of the integrated heat dissipation structure of the ring network box provided in the above embodiment is:

[0048] First, place the housing 101 in an area with a large temperature difference between day and night, then place the ring network box 121 inside the housing 101 and close the door 120.

[0049] During the day, the temperature control mechanism is in the first state, the slide plate 103 is at the upper pole, the protective cover 114 is in the contracted state, the first tube 104 is at the upper end of the second tube 105, and the liquid cooling medium in the heat-conducting tube is located in the second tube 105. After the components inside the ring network box 121 heat up, they transfer heat to the inside of the shell 101. The temperature inside the shell 101 rises, and the hot air flows upward and is discharged from the vent 102. The pressure inside the shell 101 decreases, and the cold air from the outside will enter the inside of the shell 101 from the lower position of the vent 102, so that the air inside the shell 101 circulates. When the temperature inside the shell 101 is too high, the fan 119 is started, and the fan 119 can improve the air circulation inside and outside the shell 101.

[0050] At the same time, the temperature inside the shell 101 will cause the cooling medium in the second tube 105 to evaporate. The evaporated cooling medium contacts the end of the first tube 104 and is transferred to the slide plate 103 through the heat-conducting cap 107. The vaporized cooling medium cools down and condenses after contacting the first tube 104, and flows back into the second tube 105. The phase change heat storage material in the slide plate 103 will also absorb external heat.

[0051] At night, the external environment temperature drops and is greatly different from the daytime temperature. The motor 117 is started, and the motor 117 drives the reducer 118 to work. The reducer 118 drives the threaded rod 115 to rotate. The threaded rod 115 rotates and drives the slide plate 103 to move downward through the transmission plate 116. The slide plate 103 drives the protective cover 114 to extend. Wherever the slide plate 103 passes, it is covered by the protective cover 114. The air outlet slot 113 on the slide plate 103 is gradually isolated from the through slot 112. The slide plate 103 gradually blocks the contacted through slot 112. When the slide plate 103 moves downward, it drives the second tube 105 to move downward through the first tube 104. The second tube 105 drives the frame 109 to slide downward in the groove 108. As the slide plate 103 moves, the frame 109 first slides to the lower extreme and no longer slides relative to the housing 101. The slide plate 103 moves on the threaded rod 115 The first tube 104 is driven to move downward, and at this time the first tube 104 approaches the second tube 105 relative to the second tube 105, the bellows 106 begins to shrink, and the internal space of the heat conducting tube decreases. At the same time, the first tube 104 and the second tube 105 rotate on the slide 103 and the frame 109 respectively. When the first tube 104 and the second tube 105 are at the same height, the internal space of the heat conducting tube is the smallest. The slide 103 continues to move downward, and the first tube 104 begins to slide relative to the second tube 105 in a direction away from the second tube 105, the internal space of the heat conducting tube increases, and the bellows 106 also begins to extend; the slide 103 continues to move until it reaches the lower extreme point. At this time, the temperature control mechanism is in the second state, the first tube 104 is located below the second tube 105, and the liquid cooling medium in the heat conducting tube is located in the first tube 104. At this time, the interior of the shell 101 is isolated from the outside.

[0052] The heat collected by the phase change heat storage material of the slide 103 during the day begins to be released, the pressure in the heat pipe is lower than during the day, the cooling medium is more volatile, and the heat of the slide 103 is more easily transferred to the inside of the shell 101 through the heat pipe, so that the temperature inside the shell 101 is less different from the temperature during the day.

[0053] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
