Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, and in particular to a finned array porous heat dissipation structure. Background Technology

[0002] With the continuous improvement of the integration of electronic devices and the rapid development of new energy technologies, the demand for efficient heat dissipation structures is becoming increasingly urgent. The heat dissipation structures widely used in the market mostly adopt fin array or porous designs. These structures achieve heat dissipation by increasing the heat dissipation area and enhancing convection heat transfer, which to a certain extent meets the basic heat dissipation requirements of equipment.

[0003] However, heat sinks that are welded or bolted are prone to deformation under long-term vibration or external impact, which reduces heat dissipation efficiency and shortens the life of the radiator. Traditional fixing methods cannot meet both heat dissipation performance and deformation resistance requirements. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a finned array porous heat dissipation structure, which aims to improve the problem that the heat dissipation plate is easily deformed under external impact in the existing finned array porous heat dissipation structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A finned array porous heat dissipation structure includes a first fixing plate, a first sliding rod fixedly connected to the upper surface of the first fixing plate, a heat dissipation plate slidably connected to the upper surface of the first sliding rod, a heat dissipation groove provided inside the heat dissipation plate, and a fixing component fixedly connected to the upper surface of the first fixing plate. The fixing assembly includes a second fixing plate, the lower surface of which is fixedly connected to the upper surface of the first fixing plate. A second fixing rod and a third fixing rod are fixedly connected to the outside of the second fixing plate. The lower surface of the third fixing rod is disposed on the upper surface of the heat sink, and the outside of the second fixing rod is disposed on the outside of the heat sink. The second fixing plate has a protective sleeve fixedly connected inside, a first fixing block slidably connected inside the protective sleeve, a second sliding rod fixedly connected outside the first fixing block, the second sliding rod slidably connected inside the protective sleeve, a third fixing block is provided outside the second sliding rod, the third fixing block can move with the second sliding rod inside the protective sleeve, a second fixing block is provided outside the third fixing block, the second fixing block slidably connected inside the protective sleeve, the second fixing block is fixedly connected inside the first fixing rod, a spring is provided inside the protective sleeve, and the spring is provided outside the second sliding rod. The second fixing block has a groove that mates with the third fixing block. In the locked state, the spring pushes the second sliding rod to reset, causing the third fixing block to extend into the groove of the second fixing block and confining the second fixing block within the protective sleeve.

[0006] This utility model has the following beneficial effects: 1. In this utility model, the heat sink is slidably connected to the first slide rod, the second fixing rod is disposed on the outside of the heat sink, the third fixing rod is disposed on the upper surface of the heat sink, and the first fixing rod is disposed on one side of the heat sink along the sliding direction of the first slide rod, thereby restricting the heat sink in the lateral, upper and sliding directions respectively, reducing the possibility of the heat sink shifting, falling out or deforming under external impact or vibration conditions.

[0007] 2. In this invention, the second fixing block is slidably connected inside the protective sleeve and fixedly connected inside the first fixing rod. The third fixing block and the sliding groove of the second fixing block form a snap-fit ​​engagement. The spring is used to push the second sliding rod to reset, so that the third fixing block is held in the locked position where it extends into the sliding groove of the second fixing block. Thus, the spring is only used as a reset component. The limiting of the second fixing block is mainly achieved through the mechanical snap-fit ​​between the third fixing block and the sliding groove of the second fixing block, as well as the sliding limiting of the second fixing block by the protective sleeve. This improves the stability of the first fixing rod after installation and facilitates the disassembly and maintenance of the heat sink. Attached Figure Description

Detailed Implementation

[0010] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0011] Reference Figures 1-3 An embodiment of the present invention provides a fin array type porous heat dissipation structure, including a first fixing plate 1, a first sliding rod 7 fixedly connected to the upper surface of the first fixing plate 1, a heat dissipation plate 6 slidably connected to the upper surface of the first sliding rod 7, a heat dissipation groove 5 provided inside the heat dissipation plate 6, and a fixing component 4 fixedly connected to the upper surface of the first fixing plate 1. Specifically, the first fixing plate 1 is used to support and fix the first sliding rod 7 and the fixing component 4. The first sliding rod 7 facilitates the extraction and assembly of the heat sink 6. The heat sink 6 is used to quickly absorb the heat from the heat source to avoid local heat accumulation. The heat sink 5 is used to reduce the proportion of solid material of the heat sink 6 and increase the contact area with the heat sink 6. The fixing component 4 is used to fix and restrict the position of the heat sink 6.

[0012] Reference Figures 1-3 The fixing component 4 includes a second fixing plate 402, the lower surface of which is fixedly connected to the upper surface of the first fixing plate 1, a third fixing rod 403 and a second fixing rod 401 fixedly connected to the outside of the second fixing plate 402; the lower surface of the third fixing rod 403 is disposed on the upper surface of the heat sink 6, and the outside of the second fixing rod 401 is disposed on the outside of the heat sink 6. Specifically, the second fixing plate 402 consists of two fixing plates used to support and block the second fixing rod 401 and the third fixing rod 403. The second fixing rod 401 is a square fixing rod with both ends connected to the outside of the second fixing plate 402. Its outside blocks the heat sink 6 to prevent the heat sink 6 from slipping. The third fixing rod 403 has a similar structure to the second fixing rod 401. Both ends are connected to the upper outer wall of the second fixing plate 402 to press down the heat sink 6 to prevent the heat sink 6 from falling. This can achieve the effect of resisting external forces and vibrations and avoiding deformation.

[0013] Reference Figures 4-7The second fixing plate 402 is fixedly connected to the inside of a protective sleeve 9. The protective sleeve 9 is slidably connected to the inside of a first fixing block 3. The first fixing block 3 is fixedly connected to the outside of a second sliding rod 11. The outside of the second sliding rod 11 is slidably connected to the inside of the protective sleeve 9. The outside of the second sliding rod 11 is provided with a third fixing block 12. The third fixing block 12 can move with the second sliding rod 11 inside the protective sleeve 9. The outside of the third fixing block 12 is provided with a second fixing block 8. The outside of the second fixing block 8 is slidably connected to the inside of the protective sleeve 9. The outside of the second fixing block 8 is fixedly connected to the inside of the first fixing rod 2. The protective sleeve 9 is provided with a spring 10. The outside of the spring 10 is provided to the outside of the second sliding rod 11. Specifically, the protective sleeve 9 is disposed inside the same side of the two second fixing plates 402, and is used to protect the internal structure and restrict the sliding position of the second fixing block 8. The first fixing block 3 includes a square fixing block and a cylindrical fixing block. The outer wall of the square fixing block is slidably connected to a groove opened inside the protective sleeve 9, and the cylindrical fixing block is fixedly connected to the outer wall of the second slide rod 11. The second fixing block 8 has a groove that cooperates with the third fixing block 12. The third fixing block 12 consists of two semi-circular arc fixing blocks and is used to lock the second fixing block 8. In the locked state, the spring 10 pushes the second slide rod 11 to reset, and the second slide rod 11 drives the third fixing block 12 to extend into the groove of the second fixing block 8, so that the second fixing block 8 is restricted inside the protective sleeve 9; since the second fixing block 8 is fixedly connected inside the first fixing rod 2, the first fixing rod 2 can be held on one side of the heat sink 6 along the sliding direction of the first slide rod 7, thereby preventing the heat sink 6 from sliding out. In the disassembled state, press the first fixing block 3, and the first fixing block 3 pushes the second slide bar 11 to slide inside the protective sleeve 9. The second slide bar 11 drives the third fixing block 12 to exit the slide groove of the second fixing block 8. At this time, the second fixing block 8 can be pulled out from the protective sleeve 9, and the first fixing bar 2 can be removed. Thus, the heat sink 6 can be pulled out along the first slide bar 7, achieving the effect of quick replacement and easy cleaning.

[0014] Working principle: When this structure is needed, firstly, several first sliding rods 7 are fixed on the upper surface of the first fixed plate 1. Then, one end of the heat sink 6 with a sliding groove is clamped on the outside of the first sliding rod 7, so that the heat sink 6 can slide along the first sliding rod 7. Next, two second fixed plates 402 are fixed on the upper surface of the first fixed plate 1. Then, the second fixed rod 401 and the third fixed rod 403 are fixed on the outside of the two second fixed plates 402, so that the second fixed rod 401 is located outside the heat sink 6 and the third fixed rod 403 is located on the upper surface of the heat sink 6. Thus, the second fixed rod 401 and the third fixed rod 403 respectively restrict the side and top of the heat sink 6.

[0015] Subsequently, the second fixing block 8, which is fixedly connected to the first fixing rod 2, is inserted into the protective sleeve 9. The spring 10 pushes the second sliding rod 11 to reset, causing the second sliding rod 11 to drive the third fixing block 12 into the sliding groove of the second fixing block 8. The third fixing block 12 and the sliding groove of the second fixing block 8 form a snap-fit ​​engagement. The protective sleeve 9 slides and limits the second fixing block 8, preventing it from coming out of the protective sleeve 9. Since the second fixing block 8 is fixedly connected inside the first fixing rod 2, and the first fixing rod 2 is located on one side of the heat sink 6 along the sliding direction of the first sliding rod 7, the first fixing rod 2 can limit the sliding direction of the heat sink 6. Thus, the heat sink 6 is limited by the first sliding rod 7, the second fixing rod 401, the third fixing rod 403, and the first fixing rod 2, thereby reducing the possibility of the heat sink 6 shifting, coming out, or deforming under vibration or external impact.

[0016] When the heat sink 6 needs to be replaced, press the first fixing block 3. The first fixing block 3 pushes the second slide rod 11 to slide inside the protective sleeve 9. The second slide rod 11 drives the third fixing block 12 to exit the slide groove of the second fixing block 8, so that the third fixing block 12 releases the locking restriction on the second fixing block 8. At this time, the second fixing block 8 can be pulled out from the protective sleeve 9, and the first fixing rod 2 can be removed. After the first fixing rod 2 is removed, the restriction on the heat sink 6 sliding out along the first slide rod 7 is released, and the heat sink 6 that needs to be replaced can be pulled out. When it is necessary to clean the structure, the heat sink 6 can also be pulled out one by one, which facilitates cleaning.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
