[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figures 1 to 6 shown, the present invention provides a graphene heat conduction and heat dissipation device, including a strengthening frame 1. A cooling component 2 is connected to the top of the strengthening frame 1. A number of graphene heat dissipation components 3 are movably installed inside the strengthening frame 1. The sum of the projected areas of the fronts of the a number of graphene heat dissipation components 3 is adapted to the area of the inner cavity of the strengthening frame 1;

[0028] The graphene heat dissipation component 3 includes a heat conduction plate 31 movably installed inside the strengthening frame 1. A number of evenly distributed heat dissipation fins 32 are integrally formed on the front of the heat conduction plate 31. The outer surfaces of the heat conduction plate 31 and the heat dissipation fins 32 are both smooth. The gap between adjacent heat dissipation fins 32 is the same as the width dimension of the heat dissipation fins 32 themselves. Both the bottom and the top of the heat conduction plate 31 are fixedly connected with two positioning shafts 33 on the left and right. The heat conduction plate 31 is stably connected to the strengthening frame 1 through the positioning shafts 33. Due to the setting of the positioning shafts 33, it is convenient for the staff to install the graphene heat dissipation component 3 into the strengthening frame 1 and also convenient to take out, so as to achieve the effect of facilitating the replacement of the damaged graphene heat dissipation component 3. At the same time, for the removed graphene heat dissipation component 3, by inserting the a number of heat dissipation fins 32 and their gaps on the surfaces of two heat conduction plates 31 up and down, the dust in the gaps between the a number of heat dissipation fins 32 on the surfaces of the two heat conduction plates 31 can be scraped off, achieving the effect of efficient dust removal.

[0029] Among them, the strengthening frame 1 includes an upper frame 11 clamped on the upper half of the a number of heat conduction plates 31. The lower half of the a number of heat conduction plates 31 is clamped with a lower frame 12. Both the upper frame 11 and the lower frame 12 are "U"-shaped, and the two ends of the upper frame 11 and the lower frame 12 are connected to each other.

[0030] Among them, a complete rectangular positioning frame 13 is enclosed between the upper frame 11 and the lower frame 12. A number of positioning grooves 14 are opened at both the upper and lower ends of the inner cavity of the positioning frame 13. The positioning shafts 33 are movably clamped inside the positioning grooves 14.

[0031] Among them, flow cavities 15 are opened inside both the upper frame 11 and the lower frame 12. The two ends of the upper frame 11 and the lower frame 12 are communicated with each other through the flow cavities 15.

[0032] Among them, limiting slots 16 are opened at both ends of the upper frame 11. A connecting rod 17 is slidably clamped inside the limiting slots 16. A positioning spring 18 is also arranged inside the limiting slots 16. The upper end of the positioning spring 18 abuts against the upper end of the connecting rod 17, and the lower end of the positioning spring 18 abuts against the lower end of the inner cavity of the limiting slots 16. Due to the arrangement of the limiting slots 16, the upper frame 11 and the lower frame 12 can be movably connected with the cooperation of the connecting rod 17, and under the action of the elastic recovery of the positioning spring 18, the upper frame 11 and the lower frame 12 always have a tendency to approach each other, so as to ensure that the positioning shaft 33 is always clamped inside the positioning slot 14.

[0033] Among them, the connecting rod 17 includes a limiting sliding shaft 171 movably sleeved inside the limiting slots 16. A limiting sliding rod 172 is fixedly connected to the bottom of the limiting sliding shaft 171. Communication cavities 173 that communicate with each other are opened inside both the limiting sliding shaft 171 and the limiting sliding rod 172. Due to the cooperation of the limiting sliding shaft 171 and the limiting sliding rod 172, the situation where the upper frame 11 and the lower frame 12 are completely separated can be prevented. And with the cooperation of the communication cavities 173, it can be ensured that the flow cavities 15 inside the upper frame 11 and the lower frame 12 can communicate with each other.

[0034] The outer diameter dimension of the limiting sliding shaft 171 is larger than the outer diameter dimension of the limiting sliding rod 172. The lower end of the limiting sliding rod 172 penetrates through the limiting slots 16 and extends below the upper frame 11 and is fixedly connected to the top of the lower frame 12. The limiting sliding rod 172 is sealingly sleeved inside the upper frame 11.

[0035] The upper end of the communication cavity 173 is communicated with both ends of the flow cavity 15 inside the upper frame 11, and the lower end of the communication cavity 173 is communicated with both ends of the flow cavity 15 inside the lower frame 12.

[0036] Among them, the cooling assembly 2 includes a water inlet cavity 21 and a water drainage cavity 22 opened in the middle of the upper end of the upper frame 11. The opposite surfaces of the water inlet cavity 21 and the water drainage cavity 22 are not communicated. The opposite surfaces of the water inlet cavity 21 and the water drainage cavity 22 are connected to the upper end of the flow cavity 15 inside the upper frame 11. An inlet connection head 23 and a drainage connection head 24 are fixedly connected to the top of the upper frame 11. The lower ends of the inlet connection head 23 and the drainage connection head 24 are respectively communicated with the water inlet cavity 21 and the water drainage cavity 22. Due to the arrangement of the cooling assembly 2, with the cooperation of the flow cavity 15 and the communication cavity 173, a flow circuit can be formed inside the upper frame 11 and the lower frame 12. Therefore, after the cooling medium is input from the inlet connection head 23 and the water inlet cavity 21, the cooling medium can pass through the upper frame 11 and the lower frame 12 and finally be discharged from the water drainage cavity 22 and the drainage connection head 24, so that the cooling medium circulates around a plurality of graphene heat dissipation assemblies 3, and the heat of the plurality of graphene heat dissipation assemblies 3 can be absorbed, achieving the effect of assisting in promoting heat dissipation.

[0037] Working principle and usage process of the present utility model:

[0038] As shown in the figure, assemble the device. First, the heat conducting plate 31 absorbs heat and quickly dissipates it through the heat sink 32, achieving the effect of efficient heat dissipation;

[0039] When the heat generated by the product is too large and the overall heat conduction and dissipation effect of the heat conducting plate 31 and the heat sink 32 cannot keep up, cooling medium is injected through the water inlet connector 23 and the water inlet chamber 21. Then, with the cooperation of the flow chamber 15 and the communication chamber 173, the condensing medium penetrates through the upper frame 11 and the lower frame 12 and is finally discharged through the drainage chamber 22 and the drainage connector 24. When the condensing medium passes through the upper frame 11 and the lower frame 12, it can absorb a large amount of heat energy in the heat conducting plate 31 and the heat sink 32, thereby enabling its heat to quickly dissipate;

[0040] After long-term use, due to air circulation, a large amount of dust accumulates between adjacent heat sinks 32, resulting in a decrease in the heat dissipation efficiency. At this time, overcome the clamping resistance between the positioning shaft 33 and the positioning groove 14, take out the graphene heat dissipation component 3 from the positioning frame 13, take two of the graphene heat dissipation components 3, and insert them into each other from top to bottom through the heat sink 32 and the positioning shaft 33 on their surfaces, so that the heat sink 32 on the surface of one heat conducting plate 31 scrapes the dust accumulated in the gap between the adjacent heat sinks 32 on the surface of the other heat conducting plate 31. Repeat this process to clean the dust on all graphene heat dissipation components 3, and then snap the graphene heat dissipation component 3 back into the positioning frame 13 through the positioning shaft 33 and the positioning groove 14.

Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or elements inherent to such process, method, article or device.
