Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a liquid-cooled power distribution cabinet. Background Art

[0002] A power distribution cabinet is an electrical device primarily used for power distribution and control in power distribution systems. It is typically installed in substations, distribution rooms, or industrial equipment sites, responsible for distributing electrical energy to various electrical devices and monitoring, controlling, and protecting the normal operation of circuits.

[0003] At present, when the distribution cabinet is in use, the electronic devices inside it will generate a lot of heat, which needs to be dissipated in time to ensure the normal use of the distribution cabinet. If wind power is used to accelerate the gas exchange speed inside and outside the distribution cabinet to achieve rapid heat dissipation, this heat dissipation structure will easily allow dust to enter the distribution cabinet with the wind. Long-term use may cause short circuits or corrosion of electronic devices. Therefore, liquid cooling is the mainstream structure required for heat dissipation of distribution cabinets.

[0004] When a liquid-cooled power distribution cabinet is in use, in order to maintain sufficient heat dissipation of the cabinet, it is necessary to use coolant to surround the cabinet to achieve heat exchange. In order to improve the efficiency of heat exchange, a serpentine tube is used to spiral around the side of the cabinet, and coolant is passed into the serpentine tube to ensure that the coolant can fully connect with the side wall of the cabinet to improve the heat dissipation effect. For specific methods, please refer to the Chinese utility model patent application announcement number: CN202223584496.0, which discloses a high-efficiency heat dissipation power distribution cabinet, which uses coolant to dissipate heat from the inner cabinet by setting a heat dissipation mechanism. The inner cabinet is closed during the heat dissipation process. Compared with the heat dissipation method of wind heat dissipation, it avoids the wind from bringing dust and the like into the heat dissipation cabinet;

[0005] After research, we found that the above-mentioned liquid-cooled heat dissipation solution still has the following shortcomings: the serpentine tube is coiled around the cabinet, and the contact area between the coolant in the serpentine tube and the cabinet is limited. The coolant can only achieve heat exchange through the contact area between the serpentine tube and the side wall of the cabinet, which limits the contact area between the cabinet and the serpentine tube and makes it difficult to improve the heat dissipation effect of the cabinet. At the same time, the coolant needs to absorb the heat of the inner cabinet through the serpentine tube, and the side wall of the serpentine tube affects the efficiency of the coolant in absorbing heat.

[0006] Therefore, the present application aims to increase the contact area between the coolant and the cabinet, avoid the influence of the serpentine tube side wall on the heat absorption efficiency of the coolant, and thus improve the heat dissipation effect of the cabinet. Utility Model Content

[0007] The main purpose of the present invention is to provide a method for increasing the contact area between the coolant and the cabinet, avoiding the influence of the serpentine tube side wall on the heat absorption efficiency of the coolant, and improving the heat dissipation effect of the cabinet.

[0008] In order to achieve the above-mentioned object, the present invention proposes a liquid-cooled power distribution cabinet, including a protective cabinet, wherein the protective cabinet includes:

[0009] a support portion, disposed in the cavity of the protective cabinet and forming a chamber for containing the coolant together with the protective cabinet;

[0010] A cabinet body is mounted on an end of the support portion that is higher than the cooling liquid level, and a guide groove is formed on the cabinet body from a side away from the cooling liquid to an outer wall of the support portion; and

[0011] The delivery portion is used to guide the coolant to an end of the guide groove away from the coolant.

[0012] Furthermore, the support portion includes a partition fixedly installed at the bottom of the protective cabinet chamber, a support plate, and a support base installed between the partition and the support plate, and the cabinet body is fixedly installed on the support base.

[0013] Furthermore, the delivery part includes a delivery pipe with one end connected to the coolant through the pump body, and the other end extending to the end of the guide groove away from the coolant. The delivery pipe and the pump body provide circulating coolant for the guide groove.

[0014] Furthermore, a plurality of diversion pipes are provided at one end of the delivery pipe away from the coolant, and each of the diversion pipes is arranged corresponding to the guide groove.

[0015] Furthermore, it also includes a refrigeration device installed on the side wall of the support cavity, and the refrigeration device is used to cool the cooling liquid in the support cavity.

[0016] Furthermore, it also includes a dehumidification mechanism installed on the cabinet door at the open end of the cabinet body, and the dehumidification mechanism includes a connecting pipe installed on the cabinet door, an exhaust fan installed inside the connecting pipe, and absorbent cotton arranged in the air path of the exhaust fan in the connecting pipe; wherein, both ends of the connecting pipe pass through the cabinet door and are connected to the cabinet body, forming a circulating air path composed of the cabinet body and the connecting pipe.

[0017] Furthermore, the connecting pipe is provided with a support frame at the absorbent cotton, and a telescopic rod is detachably connected to the support frame. The movable end of the telescopic rod is equipped with an extrusion plate facing the absorbent cotton. The connecting pipe is provided with a bottom box for receiving water on the side of the absorbent cotton away from the extrusion plate, and mesh panels are installed around the bottom box near the absorbent cotton.

[0018] Furthermore, the bottom box is open, a transmission rod is fixedly installed on one end of the extrusion plate facing the bottom box, a sealing plate is installed on the end of the transmission rod away from the extrusion plate to cover the opening of the bottom box, and a notch is opened at one end of the absorbent cotton to cooperate with the transmission rod.

[0019] Furthermore, it also includes a protective mechanism installed at the open end of the protective cabinet cavity, the protective mechanism includes a first support arm fixedly installed on one side of the protective cabinet, a second support arm clamped on the other side of the protective cabinet, and a protective plate is rotatably arranged between the first support arm and the second support arm.

[0020] Furthermore, a polygonal rod is inserted into one end of the protective plate close to the second support arm, and the polygonal rod is fixed to the second support arm and can be rotated to a position perpendicular to the plate surface of the protective plate. The protective plate can be rotated around the first support arm to a side away from the protective cabinet.

[0021] The above technical solution has the following advantages:

[0022] The utility model directly delivers the coolant to the guide groove through the delivery part. When the coolant moves in the guide groove, it is in direct contact with the cabinet body to absorb the heat of the cabinet body and achieve heat dissipation. Compared with the existing technology, the side wall thickness of the serpentine tube is avoided to hinder the heat absorption efficiency of the coolant, the influence of the serpentine tube on the heat absorption of the coolant is solved, and the heat absorption efficiency of the coolant is improved. The cabinet body can be taken out of the protective cabinet to facilitate cleaning and maintenance of the outer surface of the cabinet body and the inside of the protective cabinet.

[0023] By setting up a dehumidification mechanism, the air in the cabinet is circulated by the exhaust fan, and the humid air in the cabinet is absorbed by the hygroscopic cotton. The hygroscopic cotton is squeezed by the telescopic rod and the squeezing plate to ensure subsequent reuse. At the same time, when the telescopic rod is extended, the water squeezed by the hygroscopic cotton can also be discharged through the sealing plate, further ensuring the safety performance in the distribution cabinet.

[0024] By setting up a protective mechanism, it can protect both sides and the cabinet door. At the same time, the protective plate can be flipped to the other side of the cabinet and can be kept horizontal by the second support arm. Tools and corresponding electrical components can be placed on the protective plate to reduce the situation where the tools and corresponding electrical components are placed on the ground and are contaminated.

[0044] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the present invention and do not constitute a limitation to the present invention.

[0045] As described in the background technology, the serpentine tube for transporting the coolant is arranged between the main body and the inner cabinet, that is, the coolant needs to pass through the serpentine tube to absorb the heat of the inner cabinet. The existence of the serpentine tube affects the efficiency of the coolant in absorbing heat, thereby affecting the heat dissipation effect.

[0046] In order to solve this technical problem, the utility model provides a liquid-cooled power distribution cabinet.

[0047] Specifically, please refer to Figures 1-4 , a liquid-cooled power distribution cabinet specifically includes:

[0048] The protective cabinet 1 has a support portion installed at the bottom of the inner cavity of the protective cabinet 1, and the support portion forms a chamber for storing coolant in the protective cabinet 1. A cabinet body 104 is installed at the top of the protective cabinet 1, and the support portion is used to support the cabinet body 104. Several guide grooves 105 are opened between the top and both sides of the cabinet body 104. The guide grooves 105 can also be opened at the rear of the cabinet body 104, preferably only on both sides of the cabinet body 104. The support portion is provided with a conveying portion on the outer wall of the cabinet body 104, and the conveying portion is used to convey the coolant in the chamber to the guide groove 105 on the top of the cabinet body 104 to achieve liquid cooling and heat dissipation.

[0049] The present invention provides a liquid-cooled power distribution cabinet, which directly conveys the coolant to the guide groove 105 through the conveying part. When the coolant moves in the guide groove 105, it directly contacts the cabinet body 104 to absorb the heat of the cabinet body 104 and achieve heat dissipation. Compared with the existing technology, the utility model solves the influence of the serpentine tube on the heat absorption of the coolant, improves the efficiency of the coolant in absorbing heat, and also increases the contact area between the coolant and the cabinet body 104 in the guide groove 105, thereby greatly improving the heat dissipation effect.

[0050] Further, such as Figure 1-Figure 3As shown, the support part includes a partition 101 and a support plate 102 fixedly installed at the bottom of the chamber of the protective cabinet 1. A support base 103 is fixedly connected between the partition 101 and the support plate 102. The cabinet body 104 is fixed to the support base 103 by bolts. After unscrewing the bolts, the cabinet body 104 can be removed from the protective cabinet 1 to facilitate cleaning and maintenance of the outer surface of the cabinet body 104 and the inside of the protective cabinet 1.

[0051] Further, such as Figure 2-Figure 4 As shown, the delivery part includes a delivery pump placed in the chamber, and the delivery pump includes but is not limited to a submersible pump. The liquid outlet end of the delivery pump is connected to a delivery pipe 107. One end of the delivery pipe 107 extends from the back of the cabinet 104 to the top of the cabinet 104. Its purpose is to avoid the guide groove 105. Both sides of the delivery pipe 107 are fixedly connected with a number of diversion pipes 108. The diversion pipe 108 is located above the cabinet 104. The position of the diversion pipe 108 corresponds to the position of the guide groove 105. The cooling liquid in the chamber is delivered to the diversion pipe 108 through the delivery pump and the delivery pipe 107, and then discharged into the corresponding guide groove 105 by the diversion pipe 108. When the cooling liquid flows down the guide groove 105, it directly contacts the cabinet 104 to absorb the heat of the cabinet 104. The cooling liquid remains on the three side walls of the guide groove 105, which greatly increases the heating area and realizes heat dissipation. At the same time, there is no need to arrange a serpentine pipe, saving installation space and reducing the cost of the serpentine pipe.

[0052] Further, such as Figure 1-Figure 5 As shown, a supporting base 115 and several refrigeration devices 111 are fixedly installed at the bottom of the protective cabinet 1. The refrigeration device 111 can adopt refrigeration fins, compressors, condensers, etc. Its purpose is to cool the coolant in the cavity. Preferably, a refrigeration fin is adopted. The cold end of the refrigeration device 111 faces the coolant in the cavity of the protective cabinet 1. Several fans 112 are installed in the supporting base 115. The supporting base 115 can support the partition 101. The setting of the refrigeration device 111 can cool the coolant through the protective cabinet 1, and the fan 112 can accelerate the air circulation speed at the hot end of the refrigeration device 111, thereby heating the hot end of the refrigeration device 111 and discharging the heat to the outside.

[0053] As an implementation method of this embodiment, a liquid-cooled power distribution cabinet is further optimized. Specifically, Figure 1-Figure 3 As shown, a wiring tube 113 is fixedly installed on the cabinet body 104, and a socket 114 corresponding to the wiring tube 113 is opened on the protective cabinet 1. One end of the wiring tube 113 passes through the socket 114 and extends to the outside of the protective cabinet 1. A sealing ring is inserted between the outer surface of the wiring tube 113 and the socket 114. The setting of the wiring tube 113 can be used for the insertion of lines, and the setting of the sealing ring can improve the sealing effect between the wiring tube 113 and the socket 114.

[0054] Further, such as Figure 1 、 Figure 2 and Figure 5 As shown, a baffle 109 is fixedly connected to the open end surface of the cabinet body 104, a sealing gasket 110 is provided between the baffle 109 and the partition 101, and a cabinet door 106 is provided on the open end surface where the baffle 109 is located. The baffle 109 and the sealing gasket 110 cooperate with each other to seal the front of the protective cabinet 1 and the cabinet body 104.

[0055] As an implementation method of this embodiment, a liquid-cooled power distribution cabinet is further optimized, specifically, as follows Figure 5-Figure 11 As shown, the cabinet door 106 is provided with a dehumidification mechanism 2 on the outward side of the protective cabinet 1, and the dehumidification mechanism 2 includes a connecting pipe 201 fixedly installed on the front side of the cabinet door 106, and an exhaust fan 202 is fixedly installed in the connecting pipe 201. A connecting port 1 is opened between the connecting pipe 201 and the cabinet door 106, and the exhaust fan 202 can realize the circulation of air between the cabinet body 104 and the connecting pipe 201 through the connecting port 1.

[0056] Further, such as Figure 9 、 Figure 10 As shown, a support frame 212 is fixedly installed on the top of the connecting pipe 201, a bottom box 213 is fixedly installed on the bottom of the connecting pipe 201, an exhaust port 214 is provided at the bottom of the bottom box 213, and the inner cavity of the connecting pipe 201 is provided with a groove 203 corresponding to the position of the bottom box 213 and surrounding the opening of the bottom box 213.

[0057] Further, such as Figure 7-11 As shown, the top of the support frame 212 is connected to the cover plate 204 by a buckle, and a telescopic rod 205 is installed on the top of the cover plate 204. The telescopic rod 205 can be pneumatic, hydraulic or electric, preferably electric. The telescopic end of the telescopic rod 205 passes through the cover plate 204 and is fixedly connected to the extrusion plate 206. The bottom of the extrusion plate 206 is fixedly connected to the transmission rod 207. The bottom end of the transmission rod 207 passes through the groove 203 and is fixedly connected to the sealing plate 208. The sealing plate 208 is plugged into the discharge port 214, and the bottom of the discharge port 214 can be sealed through the sealing plate 208. When the telescopic rod 205 pushes the extrusion plate 206 to descend, the extrusion plate 206 can drive the sealing plate 208 to descend through the transmission rod 207, thereby sealing the bottom of the bottom box 213 through the sealing plate 208. The telescopic rod 205 is externally connected to a timing controller, which is used to control the timing start and stop of the telescopic rod 205. This is considered to be prior art.

[0058] Further, such as Figures 9-11As shown, a mesh plate 209 is placed in the groove 203, and the groove 203 can support the mesh plate 209. The transmission rod 207 passes through the mesh plate 209. Absorbent cotton 210 is placed between the mesh plate 209 and the extrusion plate 206. A gap 211 is provided on the side of the absorbent cotton 210 away from the exhaust fan 202 for the telescopic end of the transmission rod 207 to pass through. The exhaust fan 202 draws the humid air in the cabinet 104 to the gap 211. The absorbent cotton 210 can absorb moisture in the air circulation process, which can reduce the humidity in the cabinet 104. The extrusion plate 206 can squeeze the absorbent cotton 210, so that the moisture in the absorbent cotton 210 passes through the mesh plate 209 and flows to the discharge port 214.

[0059] Furthermore, the above-mentioned liquid-cooled power distribution cabinet is further optimized, such as Figure 12-15 As shown, a protective mechanism 3 is further provided on the outside of the protective cabinet 1. The protective mechanism 3 includes a second support arm 302 located on one side of the protective cabinet 1 and a first support arm 301 fixedly installed on the other side of the protective cabinet 1. The end of the first support arm 301 close to the cabinet door 106 is rotatably connected to a connecting block 303 through a rotating shaft, that is, the connecting block 303 and the first support arm 301 are rotatable. The side of the connecting block 303 close to the second support arm 302 is rotatably connected to a protective plate 304 through a rotating shaft. A gap is left between the protective plate 304 and the first support arm 301 to prevent the first support arm 301 from being tangled with the protective plate 304. To prevent the steering interference between the two arms, a polygonal groove 305 is provided on one side of the protective plate 304 close to the second support arm 302, and a polygonal rod 306 is inserted into the polygonal groove 305. An end of the polygonal rod 306 away from the first support arm 301 is fixedly connected to the second support arm 302. The cross-sections of the polygonal groove 305 and the polygonal rod 306 are polygonal. It is necessary to maintain the stable movement of the polygonal rod 306 while keeping the second support arm 302 able to be adjusted to be perpendicular to the ground. A rectangle is preferably used. The polygonal rod 306 and the polygonal groove 305 cooperate with each other to limit the position between the protective plate 304 and the second support arm 302.

[0060] The protective plate 304 further defines a receiving chamber 307 located on one side of the polygonal groove 305. A connecting rod 308 is inserted into the receiving chamber 307. One end of the connecting rod 308 penetrates the polygonal groove 305 and is fixedly connected to the polygonal rod 306. A spring is sleeved on the end of the connecting rod 308 located in the receiving chamber 307. One end of the spring abuts against the inner wall of the receiving chamber 307 on the side close to the polygonal groove 305, and the other end abuts against a stopper on the end of the connecting rod 308 away from the polygonal groove 305.

[0061] A rod 309 is fixedly connected to the side of the second support arm 302 close to the protective cabinet 1. A sleeve 310 is sleeved on the outer surface of the rod 309. One end of the sleeve 310 is fixedly connected to the protective cabinet 1. The rod 309 of the second support arm 302 is inserted into the sleeve 310 to ensure that the second support arm 302 is relatively fixed to the protective cabinet 1.

[0063] exist Figure 12 In this state, the protective plate 304, the first support arm 301 and the second support arm 302 provided in the present application can protect the protective cabinet 1 and reduce the situation where the protective cabinet 1 is hit by external forces during use, and the protective mechanism 3 can change its shape to form Figure 15 In this state, the fixing bolts 312 and the screw holes 313 are tightened and fixed. When the cabinet door 106 is opened for operation, tools and corresponding electrical components can be placed on the protective plate 304 to reduce the contamination of the tools and corresponding electrical components placed on the ground;

[0064] The form of this application is Figure 12 Switch to Figure 15 The operation is as follows: first, pull the second support arm 302 in the direction away from the protective cabinet 1, so that the insertion rod 309 is separated from the sleeve 310, and the polygonal rod 306 is separated from the polygonal groove 305, and the protective plate 304 is rotated to the horizontal position, and then the connecting block 303 is rotated to make the protective plate 304 flip over to the side of the first support arm 301 away from the protective cabinet 1, and then the second support arm 302 is rotated around the connecting rod 308 until it contacts the ground. The spring retracts the connecting rod 308 toward the accommodating cavity 307 through its own elastic force, and the polygonal rod 306 is plugged into the polygonal groove 305. Finally, the fixing bolt 312 is rotated so that the fixing bolt 312 is connected to the screw hole 313, and the position of the protective plate 304 is fixed, and it is supported by the second support arm 302 and the ground;

[0065] The form of this application is Figure 15 Switch to Figure 12The operation is as follows: rotate the fixing bolt 312 to separate the fixing bolt 312 from the screw hole 313, rotate the connecting block 303 to rotate the protective plate 304 to the side of the cabinet door 106 of the protective cabinet 1, rotate the protective plate 304 to make the protective plate 304 stand upright, that is, parallel to the cabinet door 106, pull the second support arm 302 to separate the polygonal groove 305 from the polygonal rod 306, and then rotate the second support arm 302 to a horizontal position with the connecting rod 308 as the center, insert the insertion rod 309 into the sleeve 310, and plug the polygonal rod 306 and the polygonal groove 305 together.

[0066] The use process of a liquid-cooled power distribution cabinet provided by the utility model is as follows:

[0067] Inject coolant between the partition 101 and the protective cabinet 1 in advance. The coolant is cooled by the refrigeration device 111. The delivery pump delivers the coolant to the diverter pipe 108 through the delivery pipe 107. The coolant is discharged from the diverter pipe 108 to the guide groove 105. When the coolant flows down the guide groove 105, it directly contacts the cabinet 104 and absorbs the heat of the cabinet 104, so that the heat in the cabinet 104 can be dissipated to achieve heat dissipation. After absorbing the heat, the coolant flows back to the coolant storage chamber and is cooled by the refrigeration device 111.

[0068] The exhaust fan 202 passes the air in the cabinet 104 into the connecting pipe 201. When the air in the cabinet 104 passes through the absorbent cotton 210, the absorbent cotton 210 absorbs moisture in the air, and the absorbed air returns to the cabinet 104, and the cycle repeats. When the telescopic rod 205 pushes the squeezing plate 206 to descend, the squeezing plate 206 squeezes the absorbent cotton 210 so that the moisture absorbed by the absorbent cotton 210 is squeezed out. During the process of the squeezing plate 206 descending, the transmission rod 207 drives the sealing plate 208 to descend, and a gap exists between the discharge port 214 and the sealing plate 208. The squeezed moisture is discharged from the gap at the discharge port 214. After the squeezing is completed, the telescopic rod 205 drives the squeezing plate 206 to rise. The squeezing plate 206 drives the sealing plate 208 to be inserted into the discharge port 214 through the transmission rod 207, and the gap between the discharge port 214 and the sealing plate 208 is now sealed.

[0069] When the absorbent cotton 210 needs to be replaced, open the buckle and pull the cover plate 204 upwards to remove the absorbent cotton 210, the mesh plate 209 and the sealing plate 208 from the support frame 212. Then remove the absorbent cotton 210, install the new absorbent cotton 210 between the extrusion plate 206 and the mesh plate 209, and insert the sealing plate 208 from the support frame 212. When the cover plate 204 contacts the top of the support frame 212, buckle it. The entire disassembly and assembly process is simple and easy to replace.

[0070] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
