Description

Technical Field

[0001] This utility model relates to the field of heat dissipation fins, specifically a high-efficiency heat dissipation fin structure with an annular iron core. Background Technology

[0002] When a toroidal core is in operation, if the power loss is small and the heat generated is not significant, its own thermal conduction and natural convection of the surrounding air can effectively dissipate the heat, and in this case, heat dissipation fins may not be necessary. For example, the temperature rise of some low-power toroidal transformer cores is not large during operation, and heat dissipation from the core material itself (such as silicon steel sheets) to the external environment is sufficient. However, when toroidal cores are used in high-power equipment, such as high-power transformers and reactors, the hysteresis loss and eddy current loss in the core cause the core temperature to rise rapidly. Since the heat cannot be dissipated in time, it will affect the performance and service life of the equipment. In this case, heat dissipation fins are needed to enhance heat dissipation.

[0003] However, through our long-term observation, we have found that vibrations generated during the operation of equipment with toroidal iron cores or the bumps during the transportation of vehicles with toroidal iron cores can cause deformation between the fins, reducing the distance between the fins or even causing them to stick together, thus affecting their normal heat dissipation function. Therefore, there is an urgent need for a high-efficiency heat dissipation fin structure with toroidal iron cores to solve the above defects. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency heat dissipation fin structure for annular iron cores to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, a high-efficiency heat dissipation fin structure for annular iron core is provided, comprising a heat dissipation fin body, on which multiple sets of fins are evenly arranged, and the fins are mounted on the surface of a heat-conducting plate. A first protective side plate is fixedly mounted on the left side of the surface of the heat-conducting plate, and a second protective side plate is fixedly mounted on the right side of the surface of the heat-conducting plate. The heat-conducting plate covers the surface of the heat dissipation plate, and the bottom of the heat dissipation plate is screwed to the back of the iron core equipment base. Four sets of studs are installed on both sides of the surface of the heat dissipation plate, and the studs on the heat dissipation plate pass through slots opened on the fixing seat and are fixedly connected by nuts. A connecting post is fixedly installed between the first protective side plate and the second protective side plate.

[0006] Preferably, the bottom of the first protective side plate and the second protective side plate are both fixedly installed with a fixing seat, and the fixing seat and the heat-conducting sheet are both provided with strip-shaped slots on both sides of the surface, and the fixing seat and the slots on the heat-conducting sheet are connected.

[0007] Preferably, the fins are evenly arranged in multiple groups on the surface of the heat-conducting sheet, and the bottom of the multiple groups of fins passes through the heat-conducting sheet. At the same time, the height of the bottom fins of the heat-conducting sheet is equal to the depth of the positioning opening on the surface of the heat sink.

[0008] Preferably, the distance between two adjacent sets of fins is consistent, and the fins are made of copper with a serrated structure. At the same time, the multiple sets of fins are evenly supported and reinforced by six sets of connecting columns, which pass through the multiple sets of fins.

[0009] Preferably, the fins are adapted to the size of the positioning port, and the positioning port has a serrated structure. At the same time, the portion of the fins that passes through the bottom of the heat-conducting sheet is inserted into the interior of the positioning port.

[0010] Preferably, the surfaces of the first protective side plate and the second protective side plate are each provided with four sets of equidistant flow holes, and the flow holes on the first protective side plate and the second protective side plate are connected to each other. At the same time, the flow holes on the first protective side plate and the second protective side plate are arranged in a straight line.

[0011] Preferably, the iron core equipment base and heat sink are uniformly provided with interconnected pressure relief holes, and the distance between two adjacent sets of pressure relief holes is consistent.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a sawtooth structure made of copper metal fins, which has good thermal conductivity and increases the contact area with air, thereby improving the heat dissipation effect inside the equipment. At the same time, the heat dissipation fins are detachable from the heat dissipation plate, which makes it easy to remove the heat dissipation plate separately for cleaning. This can prevent dust and other impurities in the air from accumulating on the fin surface and reducing the heat dissipation efficiency of the fins.

[0014] 2. This utility model uses a large number of fin supports evenly reinforced by six sets of equidistant connecting columns, so that the large number of fins are not easily deformed when subjected to force and vibration. This avoids the situation where the fins are deformed due to bumps and other vibrations, which would reduce the distance between the fins or even cause them to stick together, thus affecting their normal heat dissipation function.

[0020] Please see Figure 1-4 This utility model provides a high-efficiency heat dissipation fin structure for annular iron core, including a heat dissipation fin body 3, on which multiple sets of fins 37 are evenly arranged, and the fins 37 are mounted on the surface of a heat-conducting plate 31. A first protective side plate 32 is fixedly installed on the left side of the surface of the heat-conducting plate 31, and a second protective side plate 33 is fixedly installed on the right side of the surface of the heat-conducting plate 31. The heat-conducting plate 31 covers the surface of a heat dissipation plate 2. The bottom of the heat dissipation plate 2 is screwed to the back of the iron core equipment base 1. Four sets of studs are installed on both sides of the surface of the heat dissipation plate 2. The studs on the heat dissipation plate 2 pass through the slots opened on the fixing seat 35 and are fixedly connected by nuts. A connecting post 36 is fixedly installed between the first protective side plate 32 and the second protective side plate 33.

[0021] Working Principle: During use, the heat dissipation fin body 3 is installed on the back of the iron core equipment base 1. Equipment with a toroidal iron core, such as transformers and reactors, is installed in this system. The hot air generated inside the equipment can be discharged through numerous pressure relief holes 39 on the iron core equipment base 1 and the heat dissipation plate 2. Simultaneously, the heat generated inside the equipment is transferred to numerous fins 37 via heat-conducting fins 31. These fins 37, made of copper with a serrated structure, have excellent thermal conductivity and increase the contact area with air, improving the heat dissipation effect inside the equipment. Furthermore, the heat dissipation fin body 3 is detachable from the heat dissipation plate 2, facilitating individual removal for cleaning and preventing dust and other impurities from accumulating on the fin surface. The heat dissipation efficiency of the fins is affected. The disassembly method of the heat dissipation fin body 3 is as follows: remove the nut screwed to the fixed base 35, and pull out the part of the fin 37 inserted into the positioning port 38 to complete the overall disassembly of the heat dissipation fin body 3. At the same time, the bottom of the fin 37 is inserted into the positioning port 38, which ensures the stability of the fin 37 when it is dissipating heat, and also allows the fin 37 to be disassembled and cleaned at any time. A large number of fin supports are evenly reinforced by six sets of equidistant connecting columns 36, so that a large number of fins 37 are not easily deformed when subjected to force and vibration. This avoids the deformation between the fins caused by bumps and other vibrations, which would reduce the distance between the fins or even make them stick together, thus affecting their normal heat dissipation function.

[0022] In a preferred embodiment, the bottom of the first protective side plate 32 and the second protective side plate 33 are both fixedly installed with a fixing seat 35, and the fixing seat 35 and the heat-conducting plate 31 are provided with strip-shaped slots on both sides of their surfaces, and the fixing seat 35 and the slots on the heat-conducting plate 31 are connected.

[0023] Multiple sets of fins 37 are evenly arranged on the surface of the heat-conducting plate 31, and the bottom of the multiple sets of fins 37 are set through the heat-conducting plate 31. At the same time, the height of the bottom fins 37 of the heat-conducting plate 31 is equal to the depth of the positioning hole 38 opened on the surface of the heat sink 2.

[0024] In a preferred embodiment, the distance between two adjacent sets of fins 37 is consistent, and the fins 37 are made of copper with a serrated structure. At the same time, the multiple sets of fins 37 are evenly supported and reinforced by six sets of connecting posts 36, which pass through the multiple sets of fins 37.

[0025] The fins 37 are matched with the size of the positioning port 38, and the positioning port 38 has a serrated structure. At the same time, the part of the fins 37 that passes through the bottom of the heat-conducting plate 31 is inserted into the interior of the positioning port 38.

[0026] In a preferred embodiment, four sets of equidistant flow holes 34 are provided on the surface of the second protective side plate 33 of the first protective side plate 32, and the flow holes 34 on the second protective side plate 33 of the first protective side plate 32 are connected. At the same time, the flow holes 34 on the second protective side plate 33 of the first protective side plate 32 are arranged in a straight line.

[0027] The base 1 of the iron core equipment and the heat sink 2 are uniformly provided with pressure relief holes 39 connected in a manner, and the distance between two adjacent sets of pressure relief holes 39 is consistent.
