Description

Technical Field

[0001] This utility model relates to the field of heat dissipation and heat conduction pipe technology, specifically an adjustable heat dissipation and heat conduction pipe. Background Technology

[0002] With the rapid development of electronic and industrial technologies, the performance of various electronic and industrial equipment is constantly improving, and their power density is also increasing. This leads to a sharp increase in the heat generated during operation. If this heat cannot be dissipated effectively and in a timely manner, it will cause the equipment to overheat, thus affecting its performance, stability, and lifespan. For example, in the computer field, high-performance CPUs, GPUs, and other chips generate a large amount of heat during operation. If heat dissipation is not timely, the chips will reduce their operating frequency, lowering the overall performance of the computer. In the industrial field, some large mechanical equipment, such as motors and transformers, operate at high temperatures for extended periods, which accelerates the aging of internal components, increases the probability of malfunctions, and may even lead to safety accidents.

[0003] Traditional heat dissipation methods primarily rely on metal heat pipes. While metal heat pipes possess some thermal conductivity, their heat dissipation efficiency often falls short of the ever-increasing demands for high-temperature cooling. The relatively fixed structure of metal heat pipes, relying mainly on heat conduction for heat dissipation, results in a limited contact area with the surrounding air, leading to low heat dissipation efficiency and difficulty in quickly dissipating the heat generated by the equipment into the air.

[0004] Therefore, an adjustable heat pipe is provided. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable heat dissipation and heat conduction pipe, aiming to solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable heat dissipation and heat conduction pipe, including a heat dissipation pipe, wherein the heat dissipation pipe is a ring design with the ends connected, and a liquid cooling pipe is sleeved on the outer wall of the heat dissipation pipe, wherein the liquid cooling pipe is provided in several groups and is staggered on the outer wall of the heat dissipation pipe.

[0007] The heat dissipation pipe is designed to be longitudinally stretchable. The heat dissipation pipe includes a metal heat conduction pipe with openings at both the top and bottom. Each set of openings contains a set of auxiliary heat conduction pipes that slide longitudinally. The top of the upper auxiliary heat conduction pipe is fixedly connected to a first bent end, and the bottom of the lower auxiliary heat conduction pipe is fixedly connected to a second bent end. The metal heat conduction pipe, the auxiliary heat conduction pipe, the first bent end, and the second bent end are arranged in several sets and connected end to end to form the heat dissipation pipe.

[0008] Preferably, each set of auxiliary heat-conducting pipes is fitted with a set of springs on the outside. One end of each set of springs is fixedly connected to the opening inside the metal heat-conducting pipe, and the other end of each set of springs is fixedly connected to the corresponding first bent end or the corresponding second bent end.

[0009] Preferably, the auxiliary heat pipe includes an extension pipe, and the outer wall of the extension pipe is rotatably connected to heat dissipation fins via a rotating shaft. The heat dissipation fins are provided in several groups and are evenly arranged on the outer wall of the extension pipe. Each group of rotating shafts is fitted with a set of torsion springs, and the two ends of the torsion springs are fixed to the heat dissipation fins and the extension pipe, respectively.

[0010] Preferably, the liquid cooling pipe includes a corrugated liquid cooling pipe, which is a curved pipe design with the ends connected. Each set of bends in the corrugated liquid cooling pipe corresponds to each set of the metal heat-conducting pipe. The combination and installation of the liquid cooling pipe and the heat-conducting pipe are achieved by the corrugated liquid cooling pipe being clamped in the internal gap of the heat dissipation pipe.

[0011] Preferably, the corrugated liquid cooling pipe is filled with a phase change material, and two sets of conduits are installed inside the phase change material, each set of conduits being filled with alumina fluid.

[0012] Beneficial effects

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The heat dissipation pipe of this utility model adopts a longitudinally stretchable design, which can flexibly adjust the heat dissipation structure according to the heat dissipation requirements of the equipment. When the heat dissipation requirements of the equipment are large, the two sets of auxiliary heat conduction pipes can be pulled out from the inside of the metal heat conduction pipe to expand the heat dissipation area and improve the heat dissipation efficiency; when the heat dissipation requirements of the equipment are small, the auxiliary heat conduction pipes can be retracted to save space.

[0015] 2. The auxiliary heat-conducting pipe of this invention is equipped with heat dissipation fins on its exterior. When the auxiliary heat-conducting pipe is stretched outward, the heat dissipation fins unfold outward under the action of a torsion spring, effectively increasing the contact area with the air and accelerating heat dissipation. Simultaneously, a liquid cooling pipe is fitted around the heat dissipation pipe. The alumina fluid inside the liquid cooling pipe flows under the drive of a micro-pump, playing a role in cooling and heat dissipation. The phase change material can absorb or release a large amount of latent heat through changes in its physical state, achieving temperature regulation. The combination of multiple heat dissipation methods greatly improves heat dissipation efficiency.

[0016] 3. The metal heat pipe of this invention provides basic flexibility and tensile strength, ensuring the stability and reliability of the heat dissipation pipe during the stretching process. The spring plays a buffering and resetting role during the stretching and retraction of the heat pipe, making operation more convenient. The combination and installation of the corrugated liquid cooling pipe and the heat dissipation pipe is tight, which can give full play to the advantages of liquid cooling technology.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 An adjustable heat dissipation and heat conduction pipe includes a heat dissipation pipe 1, which is a ring-shaped design with the ends connected. A liquid cooling pipe 2 is sleeved on the outer wall of the heat dissipation pipe 1. The liquid cooling pipe 2 is provided in several groups and is staggered on the outer wall of the heat dissipation pipe 1.

[0026] The heat dissipation pipe 1 is designed to be longitudinally stretchable. The heat dissipation pipe 1 includes a metal heat conduction pipe 11. The top and bottom of the metal heat conduction pipe 11 are both open. A set of auxiliary heat conduction pipes 12 slides longitudinally in each set of openings. The top of the upper auxiliary heat conduction pipe 12 is fixedly connected to a first bent end 14, and the bottom of the lower auxiliary heat conduction pipe 12 is fixedly connected to a second bent end 15. The metal heat conduction pipe 11, the auxiliary heat conduction pipe 12, the first bent end 14 and the second bent end 15 are arranged in several sets and connected end to end to form the heat dissipation pipe 1.

[0027] It should be noted that the heat pipe 1 can be pre-installed on the surface of the equipment to be cooled during use, and the two sets of auxiliary heat pipes 12 can be pulled out from the metal heat pipe 11 as needed. The design of the auxiliary heat pipes 12 being able to unfold further improves the heat dissipation effect. At the same time, the metal heat pipe 11 can provide basic flexibility and tensile strength, and the liquid cooling pipe 2 outside the heat pipe 1 can be used in conjunction with the heat pipe 1, resulting in higher heat dissipation efficiency compared to the previous metal heat pipes.

[0028] In one embodiment of this utility model, such as Figures 1-6 As shown, each set of auxiliary heat-conducting pipes 12 is fitted with a set of springs 13. One end of each set of springs 13 is fixedly connected to the opening inside the metal heat-conducting pipe 11, and the other end of each set of springs 13 is fixedly connected to the corresponding first bent end 14 or the corresponding second bent end 15.

[0029] Specifically, the spring 13 is initially in a contracted state, and its use is extended as the auxiliary heat pipe 12 is pulled outward.

[0030] In one embodiment of this utility model, such as Figures 1-6 As shown, the auxiliary heat pipe 12 includes an extension pipe 121. The outer wall of the extension pipe 121 is rotatably connected to heat dissipation fins 122 via a rotating shaft. The heat dissipation fins 122 are provided in several groups and are evenly arranged on the outer wall of the extension pipe 121. Each group of rotating shafts is fitted with a set of torsion springs. The two ends of the torsion springs are fixed to the heat dissipation fins 122 and the extension pipe 121, respectively.

[0031] Specifically, when the auxiliary heat pipe 12 is stretched outward, the first bent end 14 or the second bent end 15 is stretched outward first. The heat dissipation fins 122 unfold outward under the action of the torsion spring. At this time, the spring 13 is stretched simultaneously. After the heat dissipation fins 122 are unfolded, they are stuck between the springs 13, which limits the springs 13 and prevents the springs 13 from retracting under the elastic force, which would prevent the auxiliary heat pipe 12 from unfolding. At this time, the auxiliary heat pipe 12 can dissipate the heat absorbed by the metal heat pipe 11 to the air. With the help of the heat dissipation fins 122, the contact surface with the air can be effectively expanded, thereby improving the heat dissipation efficiency.

[0032] In one embodiment of this utility model, such as Figures 1-6 As shown, the liquid cooling pipe 2 includes a corrugated liquid cooling pipe 21. The corrugated liquid cooling pipe 21 is a curved pipe design with the ends connected. Each set of bends in the corrugated liquid cooling pipe 21 corresponds to each set of metal heat conduction pipes 11. The combination and installation of the liquid cooling pipe 2 and the heat dissipation pipe 1 are achieved by clamping the corrugated liquid cooling pipe 21 into the internal gap of the heat dissipation pipe 1.

[0033] In one embodiment of this utility model, such as Figures 1-6As shown, the corrugated liquid cooling pipe 21 is filled with phase change material 22, and two sets of conduits are installed inside the phase change material 22, each set of conduits being filled with alumina fluid 23.

[0034] Specifically, a micropump is installed inside the conduit, which drives the alumina fluid 23 to flow inside the conduit, thereby cooling and dissipating heat. At the same time, the phase change material 22 can absorb or release a large amount of latent heat through physical state changes (such as solid-liquid phase change), thereby achieving temperature regulation.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] Working principle: When the adjustable heat dissipation pipe of this utility model is working, it mainly achieves efficient heat dissipation through the synergistic effect of heat dissipation pipe 1 and liquid cooling pipe 2.

[0037] When the equipment starts operating and generates heat, the metal heat pipe 11 first absorbs the heat generated by the equipment. Due to its excellent thermal conductivity, the heat can be quickly transferred to the interior of the metal heat pipe 11. If it is necessary to improve the heat dissipation efficiency, the first bent end 14 or the second bent end 15 can be stretched outward before use, causing the auxiliary heat pipe 12 to move outward from inside the metal heat pipe 11. During the outward movement of the auxiliary heat pipe 12, the heat dissipation fins 122 gradually unfold outward under the action of the torsion spring. After unfolding, the heat dissipation fins 122 are locked between the springs 13, which limit the springs 13 and prevent the springs 13 from retracting under the elastic force, thus preventing the auxiliary heat pipe 12 from not unfolding. After the auxiliary heat pipe 12 unfolds, its surface area increases significantly, which can more quickly dissipate the heat absorbed by the metal heat pipe 11 into the air. At the same time, the heat dissipation fins 122 expand the contact area with the air, further accelerating the heat dissipation.

[0038] Meanwhile, the liquid cooling pipe 2 also begins to function. The corrugated liquid cooling pipe 21 is tightly fitted into the internal gaps of the heat dissipation pipe 1, ensuring full contact and allowing it to quickly absorb the heat transferred from the heat dissipation pipe 1. The phase change material 22 filled inside the corrugated liquid cooling pipe 21 absorbs a large amount of heat through physical state changes (such as solid-liquid phase change), achieving initial temperature regulation. The micro-pump inside the conduit starts, driving the alumina fluid 23 to flow within the conduit. The alumina fluid 23 has excellent thermal conductivity, carrying away the heat absorbed by the phase change material 22 and dissipating it to the external environment through circulation, thus achieving efficient liquid cooling.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
