Description

Technical Field

[0001] This utility model relates to the field of metal fiber heat pipes, specifically a metal fiber heat pipe with high liquid absorption capacity. Background Technology

[0002] Heat pipes are heat-conducting components that rely on the phase change of their internal working fluid to achieve heat conduction. They possess characteristics such as high thermal conductivity and excellent isothermal properties, resulting in good heat conduction performance and wide applications. In recent years, with the rapid development of electronic technology, electronic devices are moving towards higher frequencies and higher speeds, and integrated circuits are becoming denser and miniaturized. The heat generation per unit volume of electronic devices has increased dramatically. Traditional heat pipes have insufficient liquid absorption capacity and high liquid return resistance, thus requiring a metal fiber heat pipe with high liquid absorption capacity.

[0003] Existing metal fiber heat pipes suffer from low thermal conductivity due to insufficient liquid absorption, high thermal resistance, and insufficient heat dissipation area. Therefore, there is an urgent need for a metal fiber heat pipe with high liquid absorption capacity. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a metal fiber heat pipe with high liquid absorption capacity to solve the problems of low thermal conductivity caused by insufficient liquid absorption, high thermal resistance loss, and insufficient heat dissipation area of ​​existing metal fiber heat pipes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a metal fiber heat pipe with high liquid absorption capacity, comprising a shell, a connection point fixedly connected to the side wall of the shell, a silicone layer installed on the outer wall of the shell, and heat dissipation fins fixedly connected to the outer wall of the shell.

[0006] The inner wall of the shell is provided with a first fiber core layer, the inner wall of the first fiber core layer is provided with a waterproof layer, the inner wall of the waterproof layer is provided with a water-absorbing layer, and the inner wall of the water-absorbing layer is provided with a second fiber core layer.

[0007] Preferably, the silicone layer is bonded to the housing, and the silicone layer is in close contact with the surface of the heat dissipation fins.

[0008] Preferably, the heat dissipation fins are spirally shaped and are sleeved with the housing.

[0009] Preferably, both the first fiber core layer and the absorbent layer are bonded to the waterproof layer, and the first fiber core layer is welded to the shell.

[0010] Preferably, the absorbent layer is arranged in a grid shape, and the absorbent layer is closely attached to the outer wall of the second fiber core layer.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention, through the setting of a first fiber core layer, a waterproof layer, a water-absorbing layer and a second fiber core layer, generates stronger capillary suction through the water-absorbing layer, which can actively adsorb and carry more liquid working fluid. The waterproof layer can effectively prevent the working fluid from leaking or lingering into non-target areas, thereby indirectly improving the effective liquid absorption efficiency of the system.

[0013] This invention utilizes a shell, a silicone layer, and heat dissipation fins. Because the heat dissipation fins are spirally shaped, they increase the effective heat dissipation area of ​​the shell several times, accelerating the heat dissipation rate of the shell. The silicone layer is used to compress and fill gaps, expelling air and ensuring a tight fit between the outer wall of the shell and the heat dissipation fins, allowing the heat from the shell to be conducted to the heat dissipation structure more efficiently.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The embodiments of this utility model will be described below based on its overall structure.

[0020] Please see Figures 1-3A high-absorption metal fiber heat pipe includes a housing 1, a connection 2 fixedly connected to the side wall of the housing 1, a silicone layer 3 installed on the outer wall of the housing 1, and heat dissipation fins 4 fixedly connected to the outer wall of the housing 1. The silicone layer 3 is bonded to the housing 1, and the silicone layer 3 is tightly attached to the surface of the heat dissipation fins 4. The heat dissipation fins 4 are spirally shaped and sleeved with the housing 1. When using the device, because the heat dissipation fins 4 are spirally shaped, the heat dissipation fins 4 can expand the effective heat dissipation area of ​​the housing 1 several times through the "three-dimensional extension" structure, increasing the contact with the surrounding air and enabling the heat transferred by the housing 1 to be dissipated into the environment more quickly through convection and radiation, thus accelerating the heat dissipation rate. Furthermore, the silicone layer 3 has good flexibility and elasticity, which can fill gaps by compression and expel air, making the outer wall of the housing 1 and the heat dissipation fins 4 tightly attached, reducing thermal resistance loss, and allowing the heat of the housing 1 to be conducted to the heat dissipation structure more efficiently.

[0021] Please see Figures 1-3 A high-absorption metal fiber heat pipe has a first fiber core layer 5 installed on the inner wall of the shell 1, a waterproof layer 6 installed on the inner wall of the first fiber core layer 5, a water-absorbing layer 7 installed on the inner wall of the waterproof layer 6, and a second fiber core layer 8 installed on the inner wall of the water-absorbing layer 7. Both the first fiber core layer 5 and the water-absorbing layer 7 are bonded to the waterproof layer 6, and the first fiber core layer 5 is welded to the shell 1. The water-absorbing layer 7 is arranged in a mesh shape and is tightly fitted to the outer wall of the second fiber core layer 8. During use, the water-absorbing layer 7 itself is made of a high-capillary-performance material. Materials such as microfiber and porous ceramics, with their fine pores and large specific surface area, can generate stronger capillary suction, actively adsorbing and carrying more liquid working fluid. Then, the waterproof layer 6 blocks the leakage or retention of the working fluid into non-target areas such as the core layer gaps and ineffective areas on the inner wall of the heat pipe, forcing the working fluid to concentrate in the effective channel between the first fiber core layer 5 and the second fiber core layer 8 of the absorbent layer 7. This avoids the "ineffective consumption" of the working fluid caused by disordered diffusion, allowing more of the limited working fluid to participate in the liquid absorption-return cycle, indirectly improving the effective liquid absorption efficiency of the system.

[0022] Working principle: In use, first move the device to a suitable position, then adhere the silicone layer 3 to the housing 1, and then fit the heat dissipation fins 4 onto the housing 1 and fix them. Then, use the connection 2 to connect the device to other equipment. During use, a continuous capillary channel is formed between the absorbent layer 7, the first fiber core layer 5, and the second fiber core layer 8, while the waterproof layer 6 fills the gaps between the core layers, reducing the risk of liquid film breakage at the interface. This allows the working fluid after liquid absorption to be transferred more smoothly to the evaporation section, avoiding the problem of "absorbing but not using" due to obstructed transmission. Overall, the liquid absorption capacity is more efficient. Furthermore, the spiral-shaped heat dissipation fins 4 can expand the effective heat dissipation area of ​​the housing 1 several times, increasing the contact with the surrounding air. The silicone layer 3 can reduce thermal resistance loss by compressing and filling the gaps, ensuring that the housing 1 is always in a state of efficient heat transfer and avoiding "heat accumulation" bottlenecks. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
