Description

Technical Field

[0001] This invention relates to the technical field of heat dissipation and waterproofing for high and low voltage distribution cabinets, specifically to a heat dissipation and waterproofing device for high and low voltage distribution cabinets. Background Technology

[0002] High and low voltage switchgear generates a large amount of heat during operation, while simultaneously needing to prevent moisture ingress to avoid short circuits or equipment damage. Therefore, the design of heat dissipation and waterproofing devices is crucial. Existing heat dissipation and waterproofing devices on the market typically work by creating ventilation holes on the sides or bottom of the switchgear when the load is low and heat dissipation requirements are not high. This allows heat to be expelled from the cabinet through natural air convection. Simultaneously, to prevent moisture from entering the switchgear through these ventilation holes, rotating heat dissipation baffles are used to block the holes, thus achieving both heat dissipation and waterproofing.

[0003] Existing heat dissipation and waterproofing devices on the market set the heat dissipation holes in the shape of air conditioner louvers for heat dissipation. In order to facilitate the automatic control of their angles, complex mechanical mechanisms are also set inside. This not only makes the cost of the entire device too high, but also makes the maintenance and production of the entire device very difficult. Due to the complex internal mechanical structure, the components are prone to wear, loosening or failure during long-term operation, which will cause the heat dissipation plate to fail to rotate normally. In addition, the complex mechanical structure is prone to the accumulation of dust and debris, affecting its normal operation. This makes the production cost of the device disproportionate to the actual operating efficiency, such as the heat dissipation louver vent setting disclosed in application number 202321601771.7 in a high and low voltage distribution cabinet. Summary of the Invention

[0004] The purpose of this invention is to provide a heat dissipation and waterproof device for high and low voltage distribution cabinets, in order to solve the problem mentioned in the background art. Currently available heat dissipation and waterproof devices on the market set the position of the heat dissipation holes in the shape of air conditioner louvers for heat dissipation. In order to facilitate the automatic control of their angles, complex mechanical mechanisms are also set inside. This not only makes the cost of the entire device too high, but also makes the maintenance and production of the entire device very difficult. Due to the complex internal mechanical structure, the components are prone to wear, loosening or failure during long-term operation, which causes the heat dissipation plate to fail to rotate normally. In addition, the complex mechanical structure is prone to the accumulation of dust and debris, affecting its normal operation, making the production cost of the device disproportionate to the actual operating efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat dissipation and waterproofing device for high and low voltage distribution cabinets, comprising an inner lining plate assembly disposed on the inner side of the cabinet panel and an outer lining plate assembly disposed on the outer side of the cabinet panel. The outer lining plate assembly has a through structure in the middle, and heat dissipation plates are disposed at equal intervals inside the through structure. The outer side of the heat dissipation plates is limited and installed by a limiting installation component, which is installed inside a reserved component. The inner lining plate assembly includes a protruding plate, a protruding hollow block, ventilation holes, and an inner lining plate. The top of the inner lining plate is integrally installed with protruding plates at equal intervals, and the top of the protruding plate is provided with a protruding hollow block. The top of the protruding hollow block is provided with through ventilation holes at equal intervals, and the interior of the protruding hollow block is connected to the ventilation holes and the channel inside the inner lining plate.

[0006] Preferably, the outer liner assembly includes two symmetrical outer liner bodies, which are bonded to each other, and reserved components are provided at equal intervals in the middle of the outer liner bodies.

[0007] Preferably, the outer liner and the inner liner assembly are made of the same material and are manufactured by injection molding. The material of the outer liner and the inner liner assembly is any one of polyethylene, polypropylene, or acrylonitrile butadiene styrene.

[0008] Preferably, the outer liner plate and the inner liner plate have the same external dimensions. Threaded through holes are provided at the four apex positions of the inner liner plate, and threaded cylinders are provided at the four apex positions of the outer liner plate, which are biased inward. The threaded cylinders correspond to the threaded through holes, and the two are installed together by mounting bolts.

[0009] Preferably, two sets of heat dissipation insulation cotton are provided between the outer liner assembly and the inner liner assembly for heat dissipation. The heat dissipation insulation cotton is made of any one of carbon fiber heat dissipation cotton, composite material heat dissipation cotton, or polytetrafluoroethylene heat dissipation cotton.

[0010] Preferably, the heat dissipation plate includes a fixed cylinder, a baffle and a reserved groove. The bottom of the fixed cylinder and the baffle are integrally formed, and the top of both sides of the fixed cylinder are provided with reserved grooves, which are semi-circular in shape.

[0011] Preferably, the limiting installation assembly includes a limiting cylinder, a limiting plate, a moving column, a return spring, and a locking cylinder. One side of the limiting cylinder is threadedly connected to the moving column, and the limiting plate is integrally installed on the outer side of the limiting cylinder biased towards the moving column. A return spring is provided on the outer side of the moving column, and a locking cylinder is integrally installed on the top of the moving column. A cylindrical rubber column is provided on the top of the locking cylinder.

[0012] Preferably, the reserved component includes mounting holes and limiting grooves. The mounting holes are set in a semi-cylindrical structure on one side of the outer liner plate, and a semi-circular limiting groove is set on the outside of the semi-cylindrical structure.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the heat dissipation and waterproof device for high and low voltage distribution cabinets;

[0015] 1. Simple structure and high reliability: In this application, injection molding is used to integrally mold each part, reducing the use of mechanical parts. Afterward, only the injection-molded parts need to be installed together to achieve the purpose of heat dissipation. There is no complex mechanical structure, fewer failure points, better reliability, and injection molding can produce a large number of consistent products in a short time, with a short production cycle and high efficiency. Compared with complex mechanical mechanisms, the injection-molded heat dissipation device has a lower production cost.

[0016] 2. Quantitative and compact design: Injection-molded materials (such as plastics or composites) are generally lighter than metals, reducing the overall weight of the distribution cabinet. This is highly advantageous for distribution cabinets that need to be moved or installed in specific locations;

[0017] 3. Convenience of maintenance: The system is equipped with a limit installation component, which allows for the disassembly and replacement of individual heat sinks. Maintenance personnel can quickly locate and replace faulty or damaged louvers, greatly reducing maintenance time and workload. The limit installation component also allows for adjustment of the initial angle of the louvers when replacing them to adapt to different heat dissipation requirements and environmental conditions.

[0018] 4. The inclined heat dissipation plate design can effectively prevent rainwater from directly entering the heat dissipation device. Combined with the heat dissipation insulation cotton filled between the outer liner plate assembly and the inner liner plate assembly, it can also enhance the sealing of the entire device and further prevent moisture from entering, achieving a double waterproof mechanism. The heat dissipation plate physically blocks and guides drainage, while the heat dissipation insulation cotton absorbs and blocks moisture. The two work together to greatly improve the waterproof performance of the entire device. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-10This invention provides a technical solution: a heat dissipation and waterproof device for high and low voltage distribution cabinets, comprising an inner lining plate assembly 3 disposed on the inner side of the cabinet panel 1 and an outer lining plate assembly 2 disposed on the outer side of the cabinet panel 1. The outer lining plate assembly 2 has a through structure in the middle, and heat dissipation plates 4 are arranged at equal intervals inside the through structure. The outer side of the heat dissipation plates 4 is limited and installed by a limiting installation assembly 9, which is installed inside a reserved assembly 10. The inner lining plate assembly 3 includes a protruding plate 31, a protruding hollow block 32, a ventilation hole 33, and an inner lining plate 34. The top of the inner lining plate 34 is integrally installed with protruding plates 31 at equal intervals, and the top of the protruding plate 31 is provided with a protruding hollow block 32. The top of the protruding hollow block 32 is provided with through ventilation holes 33 at equal intervals. The interior of the protruding hollow block 32 is connected to the ventilation holes 33 and the channel inside the inner lining plate 34.

[0032] The outer liner assembly 2 includes two symmetrical outer liner bodies 21, which are bonded together. Reserved components 10 are provided at equal intervals in the middle of the outer liner bodies 21. By engaging the two outer liner bodies 21, the limiting installation component 9 can be engaged with the reserved component 10 on the inner side of one outer liner body 21 first. Then, the other outer liner body 21 can be installed to complete the installation of the reserved component 10.

[0033] The outer liner plate 21 and the inner liner plate assembly 3 are made of the same material and are manufactured by injection molding. The material of the outer liner plate 21 and the inner liner plate assembly 3 is any one of polyethylene, polypropylene or acrylonitrile butadiene styrene. The injection molding process is used to integrally mold each part, which facilitates the subsequent processing and assembly of the entire device.

[0034] The outer liner plate 21 and the inner liner plate 34 have the same external dimensions. Threaded through holes 6 are provided at the four apex positions of the inner liner plate 34. Threaded cylinders 8 are provided at the four apex positions of the outer liner plate 21, which is biased inward. The threaded cylinders 8 correspond to the threaded through holes 6, and the two are installed together by mounting bolts 5.

[0035] This facilitates the connection between the inner liner assembly 3 and the outer liner assembly 2 using mounting bolts 5.

[0036] Two sets of heat dissipation insulation cotton 7 are provided between the outer liner assembly 2 and the inner liner assembly 3 for heat dissipation. The heat dissipation insulation cotton 7 is made of any one of carbon fiber heat dissipation cotton, composite material heat dissipation cotton, or polytetrafluoroethylene (PTFE) heat dissipation cotton. The heat dissipation insulation cotton 7 can absorb and block moisture, thereby achieving further waterproofing at the location of the heat dissipation holes.

[0037] The heat dissipation plate 4 includes a fixed cylinder 41, a baffle 42 and a reserved groove 43. The bottom of the fixed cylinder 41 and the baffle 42 are integrally formed, and the top two sides of the fixed cylinder 41 are provided with reserved grooves 43, which are semi-circular in shape.

[0038] The limiting installation assembly 9 includes a limiting cylinder 91, a limiting plate 92, a moving column 93, a return spring 94, and a locking cylinder 95. One side of the limiting cylinder 91 is threadedly connected to the moving column 93, and the limiting plate 92 is integrally installed on the outer side of the limiting cylinder 91 biased towards the moving column 93. The outside of the moving column 93 is provided with a return spring 94, and the top of the moving column 93 is integrally installed with a locking cylinder 95. The top of the locking cylinder 95 is provided with a cylindrical rubber column.

[0039] The reserved component 10 includes a mounting hole 101 and a limiting groove 102. The mounting hole 101 is set in a semi-cylindrical structure on one side of the outer liner plate 21, and a semi-circular limiting groove 102 is provided on the outside of the semi-cylindrical structure. The two mounting holes 101 and limiting grooves 102 on the two symmetrically bonded outer liner plates 21 form a complete cylinder.

[0040] The limiting groove 102 is provided with a limiting plate 92 inside, and the reset spring 94 is sleeved on the outside of the moving column 93, and the connection between the spring 94 and the moving column 93 is a detachable and installable structure.

[0041] The limiting mounting component 9 can move inside the reserved component 10. When it moves outward, the limiting mounting component 9 separates from the heat sink 4, making it easy to disassemble the heat sink 4.

[0042] Working Principle: When using this high and low voltage distribution cabinet heat dissipation and waterproof device, it is necessary to assemble the outer liner assembly 2 and the heat dissipation plate 4. First, take the moving column 93 and put the return spring 94 on its outside. Then, engage the moving column 93, the limiting cylinder 91, and the return spring 94 into the mounting hole 101. When engaging, ensure that the limiting plate 92 on the limiting cylinder 91 engages with the limiting groove 102. After that, take another outer liner 21 and bond the two outer liner 21 together. Then, the entire device can be installed on the cabinet panel 1. During installation, first take the inner liner. Component 3 is inserted into the rectangular hole on the surface of the cabinet panel 1. During installation, it is necessary to ensure that the protruding plate 31 and the protruding hollow block 32 face the inside of the cabinet panel 1. Then, take two pieces of heat dissipation insulation cotton 7 and insert them into the inside of the inner lining panel 34. After that, take the outer lining panel component 2 and insert it into the rectangular hole on the outside of the cabinet panel 1. During insertion, it is necessary to ensure that the threaded cylinder 8 faces inward and the heat dissipation plate 4 faces outward. After insertion, take the external mounting bolt 5 and thread it into the threaded hole 6 on the top of the inner lining panel 34 and the threaded cylinder 8 on the outer lining panel 21. This completes the installation of the entire device.

[0043] After the outer liner 21 is engaged and fastened to the rectangular hole on the cabinet 1, the outer side of the limiting cylinder 91 is limited by the fixing frame on the cabinet 1. This allows the limiting cylinder 91 to drive the moving column 93 at its top to always be inside the fixing cylinder 41 at the top of the baffle 42. With the rubber column at the top of the moving column 93, the baffle 42 can be installed and its angle fixed.

[0044] Subsequently, when the baffle 42 needs to be disassembled and replaced, it is only necessary to separate the outer liner assembly 2 and the inner liner assembly 3, so that the outer liner assembly 2 will be separated from the rectangular hole on the cabinet panel 1. Therefore, the top of the limiting cylinder 91 loses its limiting position. At this time, the staff applies an outward force to the moving column 93 above the reserved slot 43, and the return spring 94 resets, so that the entire limiting cylinder 91 drives the moving column 93 to move outward. Therefore, the moving column 93 will separate from the inside of the fixed cylinder 41 and reach the position of the reserved slot 43. At this time, the entire heat sink 4 can be directly disassembled and a new heat sink 4 can be installed. In this application, the top of the limiting cylinder 91 is set with a polygonal structure, so when it moves inside the mounting hole 101, it can be limited by friction, thus ensuring that it will not automatically separate from the mounting hole 101, thereby facilitating the fixing of the position of the installed heat sink 4.

[0045] In subsequent use, the hot air inside the cabinet will reach the heat dissipation insulation cotton 7 through the ventilation holes 33 on the protruding hollow block 32 for heat dissipation, and finally be discharged through the through structure on the outer lining plate 21. During the discharge, since the inclined heat dissipation plates 4 are set at equal intervals on the inner side of the through structure, the heat dissipation plates 4 can block the dust and moisture from the outside. With the setting of heat dissipation insulation cotton 7, the purpose of heat dissipation, dust prevention and waterproofing of the power distribution cabinet can be achieved.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
