Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation plates, in particular to a combined heat dissipation plate. Background Art

[0002] Existing heat dissipation plates are generally integrally formed parts made of die-casting or casting of aluminum alloy, brass or bronze, on which several heat dissipation fins are arranged. Existing heat dissipation fins are generally sheet bodies, and the heat dissipation area of the heat dissipation plate is increased by increasing the number of each heat dissipation fin. However, due to the specific shape and specifications of the integrally formed heat dissipation plate, its application range is relatively narrow, and the total area of the heat dissipation plate cannot be adjusted according to actual needs.

[0003] For example, a combined heat dissipation plate disclosed in Chinese Patent Publication No. CN216123379U includes a radiator body and a fixing frame. A cavity is formed in the radiator body, and extrusion mechanisms are installed on both the left and right sides of the inner wall of the cavity. The extrusion mechanism includes a fixed block, a spring and a first gasket. The fixed block is installed on the inner wall of the cavity, the spring is fixedly connected to the fixed block, one end of the spring away from the fixed block is fixedly connected to the first gasket, a connecting pipe is fixedly connected to the first gasket, the spring is sleeved on the connecting pipe, a water-cooling plate is arranged in the fixing frame, and fixing shells are installed on both the left and right sides of the fixing frame. One end of the fixing shell is fixedly connected to the water-cooling plate, and a second gasket is installed in the fixing shell.

[0004] However, in the above solution, it is not convenient to splice multiple heat dissipation plates, so it is not convenient to adjust the area of the heat dissipation plate according to requirements, resulting in the inability to replace a part locally when the heat dissipation plate is damaged, thus causing waste of resources and low convenience.

[0025] Please refer to Figures 1-4 In the embodiment of the present utility model, a combined heat dissipation plate includes a heat dissipation plate main body 1 and a fixing structure. Upper fixing plates 3 are fixedly connected to both the left side wall and the front side wall of the heat dissipation plate main body 1. Two rectangular holes 4 are formed in the side walls of the two upper fixing plates 3. Lower fixing plates 5 are fixedly connected to both the right side wall and the rear side wall of the heat dissipation plate main body 1. Two rectangular grooves 15 are formed in the side walls of the two lower fixing plates 5. Limiting grooves 13 are formed in both side walls at the bottom of each rectangular groove 15. The two upper fixing plates 3 are located above the two lower fixing plates 5. A plurality of heat dissipation fins 2 are provided on the top of the heat dissipation plate main body 1.

[0026] Please refer to Figure 1 、 Figures 3-4 The fixing structure includes a rectangular fixing rod 11. The rectangular fixing rod 11 is adapted to the plurality of rectangular holes 4. A top plate 8 is fixedly connected to the top of the rectangular fixing rod 11. Sliding grooves 16 are formed in both side walls at the bottom ends of the rectangular fixing rod 11. Springs 6 are fixedly connected to the side walls of the two sliding grooves 16. One end of each of the two springs 6 is fixedly connected to a limiting block 14. The two limiting blocks 14 are respectively slidably connected in the two sliding grooves 16. The two limiting blocks 14 are adapted to the limiting grooves 13 on both side walls of each rectangular groove 15. The side walls at one end of the two limiting blocks 14 are both inclined. A pulling structure is provided inside the rectangular fixing rod 11. The rectangular fixing rod 11 is passed through the rectangular hole 4 and inserted into the rectangular groove 15. When the two limiting blocks 14 abut against the top side walls of the rectangular hole 4 or the rectangular groove 15, the top side walls of the rectangular hole 4 or the rectangular groove 15 will squeeze the inclined side walls of the two limiting blocks 14, causing the two limiting blocks 14 to move into the two sliding grooves 16. The two limiting blocks 14 simultaneously squeeze the two springs 6, making the two springs 6 in a stressed state. At this time, the two limiting blocks 14 move along the side walls of the rectangular groove 15. When the two limiting blocks 14 move to beside the two limiting grooves 13, under the action of the two springs 6, one end of the two limiting blocks 14 enters the limiting grooves 13, thereby fixing the rectangular fixing rod 11 and thus fixing the two heat dissipation plate main bodies 1.

[0027] Please refer to Figure 1 、 Figures 3-4, the drawing and pulling structure includes a vertical groove 10, which is opened on the top side wall of a rectangular fixed rod 11. The top of the vertical groove 10 penetrates through the top plate 8, and a through groove 17 is opened at the bottom of the vertical groove 10. Both ends of the through groove 17 communicate with two sliding grooves 16. A pull rope 9 arranged in a Y shape is slidably connected in the vertical groove 10. The top of the pull rope 9 extends out of the vertical groove 10 and is fixedly connected to a pull ring 7. Both ends of the bottom of the pull rope 9 pass through the through groove 17 and are fixedly connected to the side walls of two limit blocks 14. Two rollers 12 are rotatably connected in the through groove 17, and the top side walls of both ends of the pull rope 9 are abutted against the outer side wall of the rollers 12. By pulling the pull ring 7, the pull ring 7 pulls the two limit blocks 14 to move through the pull rope 9, so that the two limit blocks 14 enter the sliding grooves 16, and then the top plate 8 can be lifted, thereby taking out the rectangular fixed rod 11, and thus completing the disassembly of the two heat dissipation plate bodies 1.

[0028] Please refer to Figure 1 , Figure 4 , the surface of the pull ring 7 is provided with anti-slip lines to prevent slipping when pulling the pull ring 7.

[0029] Please refer to Figure 1 , Figures 3-4 , the pull rope 9 is made of steel wire rope to increase the strength of the pull rope 9 and extend its service life.

[0030] Please refer to Figure 1 , Figure 3 , both of the two springs 6 are made of stainless steel to prevent the two springs 6 from being affected by rust and affecting their use.

[0031] The working principle of the present utility model is as follows: When it is necessary to splice and assemble multiple heat dissipation plate bodies 1, the lower fixing plate 5 on the right side of the heat dissipation plate body 1 is inserted into the bottom of the upper fixing plate 3 on the left side of another heat dissipation plate body 1, aligning the rectangular groove 15 with the rectangular hole 4. Then, the rectangular fixing rod 11 can be passed through the rectangular hole 4 and inserted into the rectangular groove 15. When the two limiting blocks 14 abut against the top side wall of the rectangular hole 4 or the rectangular groove 15, the top side wall of the rectangular hole 4 or the rectangular groove 15 will squeeze the inclined side walls of the two limiting blocks 14, causing the two limiting blocks 14 to move into the two sliding grooves 16. The two limiting blocks 14 simultaneously squeeze the two springs 6, putting the two springs 6 in a stressed state. At this time, the two limiting blocks 14 move along the side wall of the rectangular groove 15. When the two limiting blocks 14 move to the vicinity of the two limiting grooves 13, under the action of the two springs 6, one end of the two limiting blocks 14 enters the limiting grooves 13, thereby fixing the rectangular fixing rod 11 and fixing the two heat dissipation plate bodies 1, improving the stability of the two heat dissipation plate bodies 1 after connection and fixing, and preventing the two heat dissipation plate bodies 1 from detaching. According to the above method, multiple heat dissipation plate bodies 1 can be spliced according to requirements. By pulling the pull ring 7, the pull ring 7 pulls the two limiting blocks 14 to move through the pull rope 9, causing the two limiting blocks 14 to enter the sliding grooves 16. Then, the top plate 8 can be lifted to take out the rectangular fixing rod 11, thus completing the disassembly of the two heat dissipation plate bodies 1.
