Description

Technical Field

[0001] The invention relates to the field of computer heat dissipation structures, and in particular to a computer spiral heat dissipation structure. Background Art

[0002] Computer heat dissipation is a key link to ensure the stable operation of hardware. Poor heat dissipation will cause hardware overheating, which will affect performance or even damage the hardware. Computer heat dissipation methods mainly include air cooling, water cooling, heat pipe cooling, etc. Air cooling is the most common heat dissipation method. It drives air flow through a fan and transfers heat to the air through the heat sink. Water cooling takes away heat through liquid circulation and usually has higher heat dissipation efficiency. Heat pipe cooling uses the phase change heat transfer principle of heat pipes to transfer heat through the process of evaporation and condensation. Heat pipe radiators have good thermal conductivity and can reduce the volume of the radiator without affecting the heat dissipation effect.

[0003] Most of the existing heat pipe cooling structures are only used in conjunction with fan cooling. The single air cooling structure has a general effect on dissipating the heat dispersed by the fins of the heat pipe. The heat dissipation of the fins far away from the fan end is uneven, and there is no protective frame on the outside of the heat dissipation structure that is easy to disassemble. When in use, the protective frame can protect the heat dissipation structure, and it is also convenient to disassemble the protective frame for dust removal or maintenance of the heat dissipation structure.

[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Figure 1-Figure 7 The present invention is described in detail with reference to embodiments.

[0027] A computer spiral heat dissipation structure comprises a base plate 1, a support plate 2 and a plurality of heat pipes 3, wherein one end of the plurality of heat pipes 3 is partially embedded in the base plate 1 and the other end is fixed on the support plate 2, a heat insulation plate 11 is also fixedly provided on one side of the base plate 1 close to a heat dissipation fan 5, one end of the plurality of heat pipes 3 passes through the heat insulation plate 11 and the rear portion is partially embedded in the base plate 1, and the other end is fixedly provided on the outer wall of the support plate 2 or the outer wall of a support frame 13.

[0028] The bottom wall of the substrate 1 is fitted with the computer components to form a heated area. When the computer components are working, the heat generated is transferred to the substrate 1 and then to the evaporation section 23 of the heat pipe 3. Since the plurality of heat pipes 3 include a sealed tube, a liquid wick and a steam channel. The liquid wick surrounds the tube wall of the sealed tube and is soaked with a volatile working medium, which can be distilled water, ammonia, methanol or acetone, etc. The plurality of heat pipes 3 include an evaporation section 23, an insulation section 24 and a cooling section 25. The evaporation section 23 is a section embedded in the interior of the substrate 1 below the insulation board 11, the insulation section 24 is a section running through the middle of the insulation board 11, and the cooling section 25 is a section above the insulation board 11.

[0029] When the heat pipe 3 is in operation, its evaporation section 23 absorbs the heat generated by the computer components, causing the working medium in the liquid wick tube to boil and become steam. The steam with heat flows from the evaporation section 23 of the heat pipe 3 to the cooling section 25 through the insulation section 24 in sequence. When the steam transfers the heat to the cooling section 25, the steam condenses into liquid working medium. The condensed liquid returns to the evaporation section 23 through the capillary action of the liquid wick on the tube wall. The above cycle is repeated to continuously dissipate heat.

[0030] A liquid storage tank 4 is fixedly provided at the outer end of the support plate 2 through four connecting columns. A liquid inlet 14 is also provided on the outer wall of the liquid storage tank 4. The liquid inlet 14 is movably provided with a cover. By opening the cover, refrigerant can be poured into or discharged from the liquid storage tank 4 through the liquid inlet 14, which is convenient for regular replacement of the refrigerant. Both ends of a number of spiral water pipes 7 are respectively connected to the same water inlet pipe 8 and the same return pipe 9. A refrigeration plate 10 is fixedly provided inside the liquid storage tank 4 to cool the refrigerant liquid.

[0031] One end of the water inlet pipe 8 and the return pipe 9 are both connected to the liquid storage tank 4, and the other ends are respectively connected to a plurality of water distribution pipes 15. The plurality of water distribution pipes 15 can connect the plurality of spiral water pipes 7. A circulating pump 16 is also provided on the return pipe 9. The circulating pump 16 is started to drive the refrigerant to flow from the water inlet pipe 8 into the plurality of water distribution pipes 15, and then into the plurality of spiral water pipes 7, to exchange heat with the adjacent spiral fins 6, thereby accelerating the heat exchange speed of the heat pipe 3. The refrigerant after heat exchange flows back from the return pipe 9 to the liquid storage tank 4, and the cycle is repeated in this way to achieve the purpose of water circulation heat exchange.

[0032] The outer walls of the heat pipes 3 are fixedly connected with spiral fins 6 , and a spiral water pipe 7 is arranged outside each spiral fin 6 . The spiral water pipe 7 is arranged close to the spiral fin 6 and can conduct the emitted cold air to the spiral fin 6 .

[0033] The spiral water pipe 7 is coiled in the spiral gap between the spiral fins 6 and is adjacent to the spiral fins 6. The spiral water pipe 7 is a hard water pipe, such as copper or aluminum with good heat exchange performance, and is made into a spiral shape through a specific processing method so that it can be better fixed next to the spiral fins 6.

[0034] The spiral heat dissipation structure of the spiral water pipe 7 and the spiral fins 6 can provide a larger heat dissipation area within a limited volume, thereby more effectively dissipating the heat generated when the computer is running. The spiral shape design allows more heat to be transferred to the air through the increased surface area, thereby achieving faster heat dissipation.

[0035] A cooling fan 5 is arranged on the support plate 2. A through slot 12 is arranged on the support plate 2. Support frames 13 are fixedly arranged at both ends of the through slot 12. The support frame 13 is composed of a plurality of supporting circular plates and a plurality of supporting columns fixedly connected. The cooling fan 5 is fixedly arranged between the middle supporting circular plates in the support frame 13. The other supporting circular plates are used to support the other end of the heat pipe 3. When the cooling fan 5 is started, the cooling fan 5 can rotate inside the through slot 12, which can accelerate the air circulation of the heat pipe 3, take away the emitted heat, and accelerate the exchange of cold air and hot air.

[0036] The outer walls of the base plate 1 and the support plate 2 are also provided with a bolt structure 17, which is detachably connected to the protection frame 18 through the bolt structure 17. The outer wall of the protection frame 18 is a ventilation mesh plate with ventilation holes, which plays a protective role without affecting the circulation of hot air.

[0037] A plurality of threaded holes 19 are provided at one end of the protective frame 18 close to the bolt structure 17. The bolt structure 17 includes a plurality of groups of fixing blocks 20 fixed to the outer walls of the base plate 1 and the support plate 2. A threaded rod 21 is rotatably provided between each group of fixing blocks 20. The threaded rod 21 can pass through the threaded holes 19 and use nuts 22 to fix the two ends of the protective frame 18 to the base plate 1 and the support plate 2.

[0038] When it is necessary to remove dust or overhaul the spiral fins 6 and other components inside the protective frame 18, loosen the nut 22 and pull out the threaded rod 21 so that the protective frame 18 can be separated from the outer wall of the substrate 1 and the support plate 2. After the overhaul, bring the protective frame 18 close to the outer wall of the substrate 1 and the support plate 2 so that the threaded rod 21 passes through the fixing block 20 and the threaded hole 19 in turn, and tighten the nut 22 to fix the protective frame 18 on the outer wall of the substrate 1 and the support plate 2.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
