Description

Technical Field

[0001] The present invention relates to the technical field of equipment heat dissipation, and in particular to a flexible intelligent heat pipe with an adaptive telescopic grid structure. Background Art

[0002] With the rapid development of various electronic products today, the update and iteration cycle of chips is getting faster and faster. As chip performance improves and equipment operating conditions become more complex, the requirements for heat pipes, its heat transfer components, are also getting higher and higher. Although traditional rigid heat pipes can well meet the heat dissipation needs of various types of equipment in the past, they are powerless in the face of emerging devices such as folding screens where the position angle of the heating end and the heat dissipation end changes. Therefore, flexible heat pipes were born. Flexible heat pipes mean that they can bend and twist according to the requirements of use during use, which is very suitable for the heat dissipation needs of electronic products such as curved screens.

[0003] In practical applications, heat pipes face challenges beyond changes in relative position. The heat generated by modern devices during use also fluctuates significantly. A heat pipe that operates stably during initial startup may not dissipate heat properly or meet the device's cooling requirements when the device operates at high power for extended periods. Heat pipes with high-power heat transfer may not reach sufficient temperature to start up when the electronic device is first operating, leading to poor cooling performance when the device is operating at low power. Therefore, combining flexible heat pipes with intelligent heat pipes not only addresses the need for relative position changes during heat dissipation, but also increases heat transfer efficiency as the device's heat output increases, better meeting the cooling needs of modern devices.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1 to 12 , the present invention provides a technical solution:

[0037] Example 1: A flexible intelligent heat pipe with an adaptive telescopic grid structure, comprising:

[0038] The grid telescopic structure is a hollow structure with multiple pieces staggered. The purpose of the staggered structure is to utilize the gaps between the multiple pieces to achieve the bending of the flexible heat pipe, and to utilize the change in the angle formed by the staggered combination of multiple basic structures to achieve the expansion and contraction of the flexible heat pipe. The grid telescopic structure includes grid unit 1 and grid unit 2 2. An intersection 1 3 is provided on grid unit 1, and an intersection 2 4 is provided on grid unit 2 2. Grid unit 1 passes through the intersection 2 4 of grid unit 2 2 through the intersection, so that grid unit 1 1 and grid unit 2 2 are staggered.

[0039] Grid units 1 are arranged along array direction 1, and grid units 2 are arranged along array direction 2. Array directions 1 and 2 form a 90-degree angle. Through multiple arraying and interlacing, a telescopic grid structure is created. This structure is manufactured in one piece using 3D printing technology, eliminating the need for assembly.

[0040] Because grid unit 1 and grid unit 2 intersect, a certain gap is left above and below the interlocking grid units 1 and 2. This gap, in other words, exists at the junction of intersection 1 and intersection 2. In the unbent state, this gap maintains a constant width from left to right. The flexible bending of the telescopic grid is achieved by the interlocking gaps between these grid units 1 and 2. When bent, the gap between each interlaced grid unit 1 and 2 can appear wider on the left and narrower on the right, or narrower on the left and wider on the right. The combined deformation of these multiple gaps gives the telescopic grid structure a bending effect, so the longer the grid structure, the greater its bending angle.

[0041] Grid unit 1 and grid unit 2 also have lower grooves 5 to accommodate the aluminum foil shell 9 that collapses inward after vacuuming, forming multiple grooves on its surface. In actual operation, as the angle between the array direction and the cross direction increases, the overall grid telescopic structure elongates, the contact area between the aluminum foil shell 9 and the air increases, and the heat dissipation efficiency increases, making it suitable for heat dissipation during high-power overload operation of the equipment. When the angle between the array direction and the cross direction decreases, the overall grid telescopic structure shortens, the contact area between the aluminum foil shell 9 and the air decreases, and the heat dissipation efficiency decreases, making it suitable for the initial startup of the equipment or low-power operation, realizing the function of the intelligent heat pipe to adjust the heat transfer efficiency.

[0042] The gas channel 6 is opened at the center of the grid telescopic structure, so that the gaseous coolant has enough space to flow normally.

[0043] Dense copper mesh 7 is set on the side wall of the grid telescopic structure and has heat dissipation grooves 8 that fit the lower grooves 5. Dense copper mesh 7 is located on both sides of the grid telescopic structure. It is a dense thin copper mesh that has undergone a special hydrophilic treatment. It has good water absorption effect by utilizing its porous medium characteristics and has foldable properties. It serves as a channel for liquid working medium, allowing liquid working medium and gas working medium to flow in different areas. The significance of using two pieces of dense copper mesh 7 is to increase the water absorption area and improve the movement speed of the liquid working medium.

[0044] The aluminum foil membrane shell 9 is fitted with the grid structure and the dense copper mesh 7. A coolant is provided between the dense copper mesh 7 and the aluminum foil membrane shell 9. The aluminum foil membrane shell 9 is in the shape of a single-sided open box, and its length is slightly longer than the grid telescopic structure, which is convenient for vacuuming and sealing after assembly. The main function of the aluminum foil membrane shell 9 is to ensure the flow of gaseous and liquid working media inside it. The reason for using aluminum foil is that it has a certain degree of flexibility, is low in price, and is highly practical. The reason why the heat pipe needs to be evacuated is that in a vacuum environment, the boiling point of the working media inside is low, and the resistance during movement is low, so that the phase change of the internal working media can be used for heat exchange.

[0045] The original opening side of the aluminum foil membrane shell 9 is stamped and sealed to leave only a circular hole, and a liquid injection tube 10 is inserted into the aluminum foil membrane shell 9 to inject liquid working medium into the aluminum foil membrane shell 9. After the injection is completed, the aluminum foil membrane shell 9 is also sealed. After the aluminum foil membrane shell 9 is vacuumed, under the action of atmospheric pressure, the flexible aluminum foil membrane shell 9 collapses inward on the grid telescopic structure to form a new designed aluminum foil membrane shell 9 with multiple grooves.

[0046] One end is the evaporation section, and the other is the condensation section, with the two sections interchangeable during operation. When the flexible heat pipe is heated, the liquid working medium in the dense copper mesh 7 vaporizes into a gaseous working medium in the evaporation section. It then passes through the gaps between the multiple pieces of the mesh telescopic structure and reaches the hollow gas channel 6 within the mesh telescopic structure. Driven by the temperature difference, the working medium flows from the evaporation section to the condensation section. In the condensation section, it is cooled and liquefied into a liquid working medium. It then passes through the gaps between the multiple pieces of the mesh telescopic structure and is reabsorbed by the liquid channel of the super-hydrophilic dense copper mesh 7. Driven by capillary force, it flows back to the evaporation section, completing a cycle.

[0047] Example 2: The only difference between Example 2 and Example 1 is that a condensation component is provided on the condensation end of the aluminum foil membrane housing 9.

[0048] The condensation assembly includes a heat exchange plate 11 arranged on the inner wall of the condensation end, a condensation guide member arranged on the heat exchange plate 11, and a heat-conducting member arranged on the heat exchange plate 11 and located on the opposite side of the condensation guide assembly. The condensation guide member includes a condensation plate 12, a condensation plate 2 13, a condensation tank 14, a condensation tank 2 15, a guide mesh plate 1 and a guide mesh plate 2 16. The condensation plate 12 and the condensation plate 2 13 are tilted and symmetrically arranged on the heat exchange plate 11. The condensation plate 12 and the condensation plate 2 13 are fixedly connected to the heat exchange plate 11 by welding or integral molding. The tilt directions of the condensation plate 12 and the condensation plate 2 13 are opposite. The condensation plate 12 and the condensation plate 2 13 are on the heat exchange plate 11. Several groups are arranged on it, so that a condensation groove 14 and a condensation groove 2 15 are formed between the condensation plate 1 12 and the condensation plate 2 13. The condensation groove 14 is opened outward and the condensation groove 2 15 is contracted inward. The guide mesh plate 1 is arranged in the condensation groove 14, and the guide mesh plate 2 16 is arranged in the condensation groove 2 15. The guide mesh plate 1 and the guide mesh plate 2 16 are dense thin copper meshes that have undergone a special hydrophilic treatment as a whole. The ends of the guide mesh plate 1 and the guide mesh plate 2 16 are both fitted with the dense copper mesh 7. The guide mesh plate 2 16 is arc-shaped and tangent to the side wall of the condensation groove 2 15, so that the coolant condensed in the condensation groove 2 15 is absorbed by the guide mesh channel 2 and the condensate is diverted to the dense copper mesh 7.

[0049] The guide mesh plate 1 includes a curved mesh plate 17 arranged on the condensation plate 12 and the condensation plate 2 13 and tangent to the surfaces of the condensation plate 12 and the condensation plate 2 13, and an anti-leakage mesh edge 18 arranged on the curved mesh plate 17. The curved mesh plate 17 and the anti-leakage mesh edge 18 are fixedly connected by integral molding or the like. The bending direction of the curved mesh plate 17 is opposite to the bending direction of the guide mesh plate 2 16, so that the coolant condensed in the condensation tank 14 is absorbed by the curved mesh plate 17 and the condensate is diverted to the dense copper mesh 7. The anti-leakage mesh plate is used to prevent the coolant on the curved mesh plate 17 from dripping.

[0050] The heat-conducting component includes a heat-receiving pipe 19, an air inlet pipe 20, an air outlet pipe 21, a plug plate 22 and a rubber plate 23. The heat-receiving pipe 19 is fixedly connected to the heat exchange plate 11 and the aluminum foil membrane shell 9 respectively by setting a heat-conducting structural adhesive. The air inlet pipe 20 is arranged on the heat-receiving pipe 19 and passes through the aluminum foil membrane shell 9 to open downward. The air inlet pipe 20 is fixedly connected to the heat-receiving pipe 19 by means of one-piece molding, the air inlet pipe 20 is fixedly connected to the aluminum foil membrane shell 9 by means of welding, the air outlet pipe 21 is arranged on the heat-receiving pipe 19 and passes through the aluminum foil membrane shell 9 to open upward. The air outlet pipe 21 is fixedly connected to the heat-receiving pipe 19 by means of one-piece molding, the air outlet pipe 21 is fixedly connected to the aluminum foil membrane shell 9 by means of welding, the plug plate 22 is arranged on the aluminum foil membrane shell 9, the plug plate 22 is fixedly connected to the aluminum foil membrane shell 9 by means of welding, etc. The cooling tube 19 is fixedly connected to the aluminum foil membrane shell 9, the connection between the plug plate 22 and the aluminum foil membrane shell 9 is reinforced, and the rubber plate 23 is sleeved on the plug plate 22. When the evaporated coolant contacts the condensation plate 12 and the condensation plate 2 13 through the gas channel 6, it condenses and liquefies and flows to the arc mesh plate 17 and the guide mesh plate 2 16, and flows along the arc mesh plate 17 and the guide mesh plate 2 16 to the dense copper mesh 7. The heated tube 19 absorbs the heat emitted when the coolant condenses, and the hot air is discharged from the outlet pipe 21, and the cold air enters the heated tube 19 from the inlet pipe 20. When the notch formed after the heat dissipation groove 8 is attached to the aluminum foil membrane shell 9 is closed, the air inlet of the inlet pipe 20 is attached to the rubber plate 23, which prevents cold air from entering the heated tube 19, reducing the condensation efficiency, thereby reducing the heat dissipation efficiency, and better changing the heat dissipation efficiency.

[0051] Working principle: When in use, the grid telescopic structure is extended as a whole, the contact area between the aluminum foil membrane shell 9 and the air is increased, and the heat dissipation power is increased, which is suitable for the heat dissipation state when the equipment is running at high power and overload; the angle between the array direction and the cross direction is reduced, the grid telescopic structure is shortened as a whole, the contact area between the aluminum foil membrane shell 9 and the air is reduced, and the heat dissipation power is reduced, which is suitable for the initial startup of the equipment or the state when it is running at low power.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
