Description

Technical Field

[0001] The present application relates to the field of control cabinets, and in particular to a high-efficiency heat dissipation control cabinet. Background Art

[0002] The control cabinet is a closed or semi-closed metal cabinet in which switchgear, measuring instruments, protective electrical equipment and auxiliary equipment are assembled according to the electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system and be easy to maintain without endangering the safety of operators and surrounding equipment.

[0003] During the use of existing power control cabinets, the electronic components inside the instrument will generate heat when powered on. A large amount of heat accumulation will increase the ambient temperature inside the control cabinet. Long-term exposure to high temperature will shorten the service life of the electronic components in the control cabinet and cause safety hazards. Existing control cabinets dissipate heat through their own openings, and the heat dissipation effect is poor. Summary of the invention

[0004] In order to improve the defect of low heat dissipation efficiency of traditional control cabinets, the present application provides a high-efficiency heat dissipation control cabinet.

[0005] This application provides an efficient heat dissipation control cabinet, which adopts the following technical solutions:

[0006] A high-efficiency heat dissipation control cabinet comprises a cabinet body, a working cavity for placing electrical components is arranged in the cabinet body, an inlet and outlet communicated with the working cavity are opened on one side of the outer wall of the cabinet body, a cabinet door hinged to the cabinet body is arranged on the inlet and outlet, an air outlet is arranged on the cabinet door, a first frame is arranged in the working cavity, a horizontal and U-shaped slide rail is arranged on the first frame, and the opening direction of the slide rail faces the direction close to the inlet and outlet, a second slider is slidably arranged in the slide rail along its length direction, a first slide groove which is the same as the length direction of the slide rail is arranged on the inner wall of the working cavity, and a first slider is slidably arranged in the first slide groove along its length direction; the first slide groove and the slide rail are located in the same horizontal plane, and the second slider is located between the first slider and the second slider. A heat dissipation component is fixedly arranged, and the heat dissipation component includes a vertically arranged cooling cylinder; a liquid storage chamber for placing coolant is arranged in the cooling cylinder, and two heat exchange chambers are also arranged in the cooling cylinder, the two heat exchange chambers are symmetrically arranged and located on both sides of the liquid storage chamber, and a first heat exchange hole is opened on the end surface of the heat exchange chamber away from each other at one end in the horizontal direction; two heat exchange boxes are arranged on the first rack, and the two heat exchange boxes are symmetrically arranged at both ends of the slide rail, and dry ice is placed in the heat exchange boxes, and the side surfaces of the two heat exchange boxes close to the slide rail are provided with second heat exchange holes arranged opposite to the first heat exchange hole, and a heat exchange pipe is fixedly penetrated in the second heat exchange hole, and the end of the heat exchange pipe away from the heat exchange box can be slid in the first heat exchange hole in the horizontal direction.

[0007] By adopting the above technical solution, the first frame is set up so that a slide rail can be set on the first frame; by setting the slide rail to be U-shaped and with the opening direction facing the direction close to the entrance and exit, the second slider can be slidably set in the slide rail along its length direction, and the second slider does not affect the opening and closing of the cabinet door and the use of the entrance and exit when sliding in the slide rail; the first slide groove is set up so that the first slider can be slidably set in the first slide groove; by setting the length direction of the first slide groove to be the same as the length direction of the slide rail, the distance between the second slider and the first slider during the sliding process can be equal, so that the heat dissipation component can be fixedly set between the second slider and the first slider, so that The sliding of the second slider and the first slider drives the heat dissipation component to move in the working chamber, thereby increasing the contact area between the heat dissipation component and the air in the working chamber, thereby improving the heat dissipation efficiency to a certain extent, thereby improving the defect of low heat dissipation efficiency of the traditional control cabinet to a certain extent; through the setting of the cooling cylinder, a liquid storage chamber can be set in the cooling cylinder, so that coolant can be placed in the liquid storage chamber, and through the setting of the coolant, the heat exchange speed between the coolant and the heat in the air can be further accelerated, and the heat dissipation efficiency can be further improved; through the setting of the heat exchange chamber, a first heat exchange hole can be set on the heat exchange chamber; through the setting of the heat exchange box, dry ice can be placed in the heat exchange box , by setting the second heat exchange hole, the heat exchange tube can be fixedly installed in the second heat exchange hole; when the cooling tube moves toward the direction close to the heat exchange box, the heat exchange tube can be installed in the first heat exchange hole. At this time, the heat exchange tube connects the inside of the heat exchange box with the inside of the heat exchange cavity. The heat exchange box is in direct contact with the heat exchange cavity. The heat of the heat exchange cavity is transferred to the heat exchange box, so that the temperature of the inner wall of the heat exchange box increases. The dry ice in the heat exchange box rapidly expands and sublimates under the condition of contact with the heat exchange box with increased temperature, and is transferred to the heat dissipation cavity through the heat exchange tube. At this time, the air pressure in the heat dissipation cavity and the heat exchange box increases sharply. Under the action of the air pressure, the cooling tube moves in the direction away from the heat exchange box and moves in the direction close to the other heat exchange box. During this movement, the sublimated carbon dioxide in the heat dissipation chamber absorbs a large amount of the ambient temperature in the chamber, which reduces the temperature in the heat dissipation chamber and cools the coolant in the liquid storage chamber. The continuously expanded carbon dioxide enters the working chamber from the first heat exchange hole and the second heat exchange hole respectively, thereby absorbing the air temperature in the working chamber, reducing the air temperature in the working chamber, and further improving the heat dissipation efficiency; when the cooling cylinder moves to a position close to another heat exchange box, another heat exchange tube is inserted into another first heat exchange hole, and the sublimation process of dry ice is repeated, so that the cooling cylinder moves in the opposite direction again, further improving the heat dissipation efficiency of the control cabinet; improving the defect of low heat dissipation efficiency of traditional control cabinets.

[0008] Optionally, a second magnet sheet is provided on a side of the heat exchange box close to the slide rail, and a first magnet sheet that attracts the second magnet sheet is provided on a side of the outer wall of the heat exchange cavity close to the heat exchange box.

[0009] By adopting the above technical solution, when the cooling cylinder moves to a position close to the heat exchange box, the first magnet sheet and the second magnet sheet can be adsorbed together, thereby fixing the cooling cylinder and the heat exchange box. At this time, the end of the heat exchange tube away from the heat exchange box is inserted into the first heat exchange hole. The temperature rises of the dry ice causes the air pressure in the heat exchange box and the heat exchange cavity to rise sharply. When the force of the air pressure is greater than the suction force between the first magnet sheet and the second magnet sheet, the cooling cylinder can be separated from the heat exchange box and move in a direction away from the heat exchange box. The cooling cylinder performs a cyclic reciprocating motion between the two heat exchange boxes. When the air pressure force is less than the suction force between the first magnet sheet and the second magnet sheet, the cooling cylinder can be moved away from the heat exchange box. When the suction force between the first and second magnet sheets is applied, the cooling cylinder can be fixed on the heat exchange box; therefore, through the arrangement of the first magnet sheet and the second magnet sheet, the cooling cylinder can be limited, so that the cooling cylinder is fixedly connected to one of the heat exchange boxes when it does not need to work, so that the cooling cylinder can circulate from one heat exchange box to another heat exchange box when it needs to work, thereby avoiding the cooling cylinder staying in the middle position between the first slide groove and the slide rail after heat exchange. When it needs to work again, the cooling cylinder needs to be manually moved to the side of the heat exchange box, which increases manpower and improves work efficiency.

[0046] Reference Figure 6 and Figure 8 A first cylinder 125 electrically connected to the controller 114 is fixedly arranged on the side wall of the storage chamber 12 near the terminal of the conveyor belt 122. The cylinder body of the first cylinder 125 is arranged horizontally and the length direction is perpendicular to the length direction of the conveyor belt 122. The first cylinder 125 is located above the terminal of the conveyor belt 122, and a push plate 126 is fixedly connected to the end of the piston rod of the first cylinder 125 away from the cylinder body. The cross section of the push plate 126 is Z-shaped and includes a top plate 1261, a bottom plate 1263 and a web 126. 2. The top plate 1261 is perpendicular to the length direction of the piston rod and is fixedly connected to the piston rod at one end close to the piston rod. The web 1262 is perpendicularly arranged to the top plate 1261 and is located on the side of the first cylinder 125 close to the terminal of the conveyor belt 122. One end of the web 1262 is fixedly connected to the top plate 1261, and the other end is connected to the bottom plate 1263. The top plate 1261 and the bottom plate 1263 are respectively located on both sides of the web 1262, and the bottom plate 1263 is located on the side of the storage chamber 12 away from the first replacement port 124.

[0047] Open the cover plate 16, put dry ice 4 into the placement opening 15, the dry ice 4 falls from the placement opening 15 to the top guide plate 123, slides from the guide plate 123 to the bottom guide plate 123 and then falls to the initial end of the conveyor belt 122, the conveyor belt 122 moves the dry ice 4 from the initial end to the terminal end, and abuts against the side of the web 1262 of the push plate 126 away from the first cylinder 125; put a plurality of dry ice 4 in turn, so that the guide plate 123 and the conveyor belt 122 are full of dry ice 4, and the dry ice 4 is arranged in sequence along the length direction of the guide plate 123 and the conveyor belt 122 When the temperature sensor 113 measures that the air temperature in the working chamber 11 reaches a preset upper limit, the temperature sensor 113 transmits a temperature signal to the controller 114. The controller 114 controls the second cylinder 117 to drive the sealing plate 52 to move vertically upward, so that the heat exchange box 3 and the storage chamber 12 can be connected through the positioning frame 5. At this time, the controller 114 controls the first cylinder 125 to drive the push plate 126 to move toward the direction close to the first replacement port 124, and the bottom plate 1263 drives the dry ice 4 to move from the conveyor belt 122 to the positioning frame 5 and then from the positioning frame 5 to the heat exchange box 3.

[0048] The implementation principle of an efficient heat dissipation control cabinet in the embodiment of the present application is as follows: before the control cabinet is operated, the cover plate 16 is first opened, and dry ice 4 is placed in the placement port 15. The dry ice 4 falls from the placement port 15 onto the top guide plate 123, slides from the guide plate 123 to the bottom guide plate 123, and then falls onto the initial end of the conveyor belt 122. The conveyor belt 122 moves the dry ice 4 from the initial end to the terminal end, and abuts against the side of the web 1262 of the push plate 126 away from the first cylinder 125; several pieces of dry ice 4 are placed in sequence, and the dry ice 4 is arranged in sequence along the length direction of the guide plate 123 and the conveyor belt 122, so that the guide plate 123 and the conveyor belt 122 are filled with dry ice 4, reaching the upper limit of the number of dry ice 4 placed in the storage chamber 12, which can avoid the need to repeatedly put dry ice 4 into the storage chamber 12. When the control cabinet is working, when the temperature sensor 113 measures that the air temperature in the working chamber 11 reaches the preset upper limit, the temperature sensor 113 transmits the temperature signal to the controller 114, and the controller 114 controls one of the second cylinders 117 to drive the sealing plate 52 to move vertically upward, so that the heat exchange box 3 and the storage chamber 12 can be connected through the positioning frame 5. At this time, the controller 114 controls the first cylinder 125 to drive the push plate 126 to move in the direction close to the first replacement port 124, and the bottom plate 1263 drives the dry ice 4 to move from the conveyor belt 122 to the positioning frame 5 and then from the positioning frame 5 to the heat exchange box 3. At this time, the dry ice 4 contacts the heat exchange box 3 and sublimates rapidly under the influence of the heat of the heat exchange box 3. The sublimated dry ice 4 flows into the heat exchange chamber 212 through the heat exchange tube 32, causing the air pressure in the heat exchange chamber 212 and the heat exchange box 3 to rise sharply; the sharply rising air pressure generates a force to separate the cooling cylinder 21 from the heat exchange box 3 When the air pressure force is greater than the force of attraction between the first magnet piece 2122 and the second magnet piece 33, the cooling cylinder 21 moves in the direction away from the heat exchange box 3, and is fixed to another heat exchange box 3 by adsorption by another group of first magnet pieces 2122 and second magnet pieces 33; the dry ice 4 entering the heat exchange chamber 212 absorbs the heat inside the heat exchange chamber 212, cools the inside of the heat exchange chamber 212, and cools the liquid storage chamber 211 at the same time, and enters the working chamber 11 from the first heat exchange hole 2121 during the expansion process, and cools the working chamber 11; when the temperature sensor 113 measures that the temperature in the working chamber 11 reaches the preset upper limit again, the controller 114 controls another group of conveyor belts 122, the second cylinder 117 and the first cylinder 125 to work, so that the cooling cylinder 21 can move back and forth in the working chamber 11, and cool the working chamber 11 through the contact between the coolant and the air and the sublimation of the dry ice 4.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
