Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat pipe technology, specifically a heat pipe capable of withstanding pressure. Background Technology
[0002] A heat pipe is a lightweight and small heat transfer element. Because its heat transfer efficiency is much higher than that of ordinary metal materials, it is widely used in the heat dissipation of electronic products. The working principle of existing heat pipes is as follows: a working fluid is placed inside the tube. One end of the tube is connected to the heating element, and the other end is connected to the condenser. The working fluid is heated at the heated end and turns into a vapor flow to the other end. After releasing heat through the condenser, it condenses into a liquid state and then flows back to the heated end through the capillary structure inside the tube.
[0003] Based on the above, the inventors have discovered the following problems: the existing hollow structure design of heat pipes focuses too much on the flow of working fluid and heat conduction efficiency, while neglecting the improvement of pressure resistance, lacking effective reinforcement structure, and unable to withstand large pressure.
[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a heat pipe that can withstand pressure, in order to achieve a more practical purpose. Utility Model Content
[0005] The purpose of this invention is to provide a pressure-bearing heat pipe to solve the problem of the hollow structure design of existing heat pipes mentioned in the background art, which focuses too much on the flow of working fluid and heat conduction efficiency, while neglecting the pressure-bearing capacity.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0007] A pressure-bearing heat pipe, comprising:
[0008] The outer casing has a liquid-absorbing core on its inner wall;
[0009] A pressure-bearing mechanism is located inside the outer shell. The pressure-bearing mechanism includes a support tube. The upper and lower ends of the support tube are respectively connected to the upper and lower ends of the inner shell. The interior of the support tube is set as a hollow structure. The upper and lower ends of the support tube are respectively fitted with a first reinforcing block and a second reinforcing block. Several third reinforcing blocks are wound around the outside of the support tube between the first and second reinforcing blocks.
[0010] Furthermore, the first reinforcing block, the second reinforcing block, and the third reinforcing block are of the same shape and size, and the third reinforcing blocks are distributed at equal intervals.
[0011] The beneficial effect of adopting the above-mentioned further solution is that the first reinforcing block, the second reinforcing block and the third reinforcing block are the same in shape and size and several third reinforcing blocks are distributed at equal intervals. With the support of the first reinforcing block, the second reinforcing block and the third reinforcing block, the force on the outside of the heat pipe is more uniform, avoiding local stress concentration and further enhancing the overall pressure resistance stability of the heat pipe.
[0012] Furthermore, a plurality of reinforcing rods are inserted between the third reinforcing blocks, and the upper and lower ends of the plurality of reinforcing rods are respectively connected to the bottom end of the first reinforcing block and the upper end of the second reinforcing block.
[0013] The beneficial effect of adopting the above-mentioned further solution is that the reinforcing rods inserted between the third reinforcing blocks are connected at their upper and lower ends to the first and second reinforcing blocks respectively, forming a three-dimensional support structure. This enhances the overall strength and rigidity of the pressure-bearing mechanism, improves the heat-conducting pipe's resistance to deformation, and thus improves its pressure-bearing capacity. Furthermore, the reinforcing rods are circumferentially distributed along the axis of the support pipe.
[0014] The beneficial effect of adopting the above-mentioned further solution is that the reinforcing rods are distributed circumferentially along the axis of the support tube, making the pressure-bearing mechanism more uniform in the circumferential direction, which can better cope with the pressure from all directions, and further enhance the pressure-bearing performance and stability of the heat pipe.
[0015] Furthermore, the outer edges of the first reinforcing block, the second reinforcing block, and the third reinforcing block are each provided with a plurality of through holes, which are distributed circumferentially along the axis of the support tube.
[0016] The beneficial effect of adopting the above-mentioned further solution is that the several through holes opened on the outer edge of the first reinforcing block, the second reinforcing block and the third reinforcing block are distributed circumferentially along the axis of the support tube. These through holes can increase the flow channels of liquid in the heat pipe, promote the circulation of liquid and the transfer of heat, improve the heat conduction efficiency of the heat pipe, and at the same time reduce the weight of the reinforcing block to a certain extent and reduce the cost.
[0017] Furthermore, the outer sides of the first, second, and third reinforcing blocks abut against the inner side of the liquid-absorbing core.
[0018] The beneficial effect of adopting the above-mentioned further solution is that the outer sides of the first reinforcing block, the second reinforcing block and the third reinforcing block abut against the inner side of the liquid-absorbing core, so that the pressure-bearing mechanism is tightly combined with the liquid-absorbing core, thereby enhancing the stability of the liquid-absorbing core and improving the pressure-bearing performance of the entire heat pipe.
[0019] Furthermore, the outer shell is made of brass, and the liquid-absorbing core is made of carbon fiber.
[0020] The beneficial effects of adopting the above-mentioned further solution are that the outer shell is made of brass, which has good thermal conductivity and corrosion resistance, ensuring the efficient heat conduction and long-term use of the heat pipe. The liquid wick is made of carbon fiber, which has high specific strength, high specific modulus, good chemical stability and adsorption performance, which helps to improve the liquid adsorption and transport capacity of the liquid wick, thereby improving the heat conduction efficiency of the heat pipe.
[0021] Furthermore, the interior of the outer casing is filled with a working fluid.
[0022] The beneficial effect of adopting the above-mentioned further scheme is that when one end of the heat pipe is heated, the working fluid absorbs heat and evaporates into steam. Under the action of pressure difference, the steam quickly flows to the other end of the heat pipe. At the cooler end, the steam releases heat and condenses into liquid. The liquid then flows back to the heated end through the capillary action of the wick. This cycle repeats, achieving efficient heat transfer.
[0023] Compared with the prior art, the beneficial effects of this utility model are as follows: The heat pipe capable of bearing pressure has an outer shell as the main structure of the heat pipe. The liquid-absorbing core on its inner wall helps the adsorption and transmission of the working fluid, promoting heat transfer. The pressure-bearing mechanism is set inside the outer shell. The upper and lower ends of the support tube are connected to the outer shell to provide support for the outer shell and enhance the pressure-bearing capacity of the two ends of the heat pipe. The first reinforcing block, the second reinforcing block, and the third reinforcing block further reinforce the support tube and improve the pressure resistance of the side of the heat pipe. The support tube cooperates with the first reinforcing block, the second reinforcing block, and the third reinforcing block to improve the pressure-bearing capacity of the entire heat pipe. The first reinforcing block, the second reinforcing block, and the third reinforcing block are the same in shape and size, and several third reinforcing blocks are evenly distributed. Under the support of the first reinforcing block, the force on the outside of the heat pipe is more uniform, avoiding local stress concentration and further enhancing the overall pressure-bearing stability of the heat pipe.

[0030] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a pressure-bearing heat-conducting pipe, comprising: a shell 100, with a liquid-absorbing core 102 provided on the inner wall of the shell 100; a pressure-bearing mechanism 101, disposed inside the shell 100, the pressure-bearing mechanism 101 including a support tube 10101, the upper and lower ends of the support tube 10101 being connected to the upper and lower ends of the interior of the shell 100 respectively, the interior of the support tube 10101 being a hollow structure, the upper and lower ends of the support tube 10101 being respectively fitted with a first reinforcing block 10102 and a second reinforcing block 10103, and a plurality of third reinforcing blocks 10104 being wound around the outside of the support tube 10101 between the first reinforcing blocks 10102 and the second reinforcing blocks 10103. The outer shell 100 serves as the main structure of the heat pipe. The liquid-absorbing core 102 on its inner wall helps the adsorption and transmission of the working fluid, promoting heat transfer. The pressure-bearing mechanism 101 is located inside the outer shell 100. The upper and lower ends of the support tube 10101 are connected to the outer shell 100 to provide support for the outer shell 100 and enhance the pressure-bearing capacity at both ends of the heat pipe. The first reinforcing block 10102, the second reinforcing block 10103, and the third reinforcing block 10104 further reinforce the support tube 10101 and improve the pressure resistance of the side of the heat pipe. The support tube 10101 cooperates with the first reinforcing block 10102, the second reinforcing block 10103, and the third reinforcing block 10104 to improve the pressure-bearing capacity of the entire heat pipe.
[0031] 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.
[0032] Please see Figure 1 - Figure 5The first reinforcing block 10102, the second reinforcing block 10103, and the third reinforcing block 10104 are identical in shape and size, and are evenly spaced. Several reinforcing rods 10105 are inserted between the third reinforcing blocks 10104. The upper and lower ends of the reinforcing rods 10105 are connected to the bottom end of the first reinforcing block 10102 and the upper end of the second reinforcing block 10103, respectively. The reinforcing rods 10105 are circumferentially distributed along the axis of the support tube 10101. Several through holes 10106 are formed on the outer edges of the first reinforcing block 10102, the second reinforcing block 10103, and the third reinforcing block 10104, and are circumferentially distributed along the axis of the support tube 10101. The first reinforcing block 10102... The outer sides of the second reinforcing block 10103 and the third reinforcing block 10104 abut against the inner side of the liquid-absorbing core 102. The outer shell 100 is made of brass, and the liquid-absorbing core 102 is made of carbon fiber. The interior of the outer shell 100 is filled with working fluid. The first reinforcing block 10102, the second reinforcing block 10103, and the third reinforcing block 10104 are the same in shape and size, and several third reinforcing blocks 10104 are evenly distributed. With the support of the first reinforcing block 10102, the second reinforcing block 10103, and the third reinforcing block 10104, the force on the outer side of the heat pipe is more uniform, avoiding local stress concentration and further enhancing the overall pressure resistance stability of the heat pipe. The reinforcing rods 10105 inserted between the third reinforcing blocks 10104 are respectively connected to the first reinforcing blocks at their upper and lower ends. The first reinforcing block 10102 and the second reinforcing block 10103 are connected to form a three-dimensional support structure, which enhances the overall strength and rigidity of the pressure-bearing mechanism 101, improves the heat pipe's resistance to deformation, and thus enhances its pressure-bearing capacity. The reinforcing rods 10105 are distributed circumferentially along the axis of the support pipe 10101, making the force on the pressure-bearing mechanism 101 more uniform in the circumferential direction, and better able to cope with pressure from all directions, further enhancing the pressure-bearing performance and stability of the heat pipe. Several through holes 10106 opened on the outer edges of the first reinforcing block 10102, the second reinforcing block 10103, and the third reinforcing block 10104 are distributed circumferentially along the axis of the support pipe 10101. These through holes 10106 can increase the flow channels of liquid in the heat pipe and promote the flow of liquid. The circulation and heat transfer of the heat pipe improve the heat conduction efficiency of the heat pipe, while also reducing the weight of the reinforcing blocks to some extent, thus lowering costs. The outer sides of the first reinforcing block 10102, the second reinforcing block 10103, and the third reinforcing block 10104 abut against the inner side of the liquid-absorbing core 102, ensuring a tight connection between the pressure-bearing mechanism 101 and the liquid-absorbing core 102, enhancing the stability of the liquid-absorbing core 102, and improving the pressure-bearing performance of the entire heat pipe. The outer shell 100 is made of brass, which has good thermal conductivity and corrosion resistance, ensuring efficient heat conduction and long-term use of the heat pipe. The liquid-absorbing core 102 is made of carbon fiber, which has high specific strength, high specific modulus, good chemical stability, and adsorption properties, helping to improve the liquid adsorption and transport capacity of the liquid-absorbing core 102.This improves the thermal conductivity of the heat pipe. When one end of the heat pipe is heated, the working fluid absorbs heat and evaporates into steam. Under the pressure difference, the steam quickly flows to the other end of the heat pipe. At the cooler end, the steam releases heat and condenses into liquid. The liquid then flows back to the heated end through the capillary action of the wick 102. This cycle repeats continuously, achieving efficient heat transfer.
[0033] Specifically, the working principle of this pressure-bearing heat pipe is as follows: The outer shell 100 serves as the main structure, and its inner wall has a liquid-absorbing core 102 made of carbon fiber. Utilizing its high specific strength, high specific modulus, good chemical stability, and adsorption performance, it adsorbs and transfers the working fluid filled inside the outer shell 100. When one end of the heat pipe is heated, the working fluid absorbs heat and evaporates into steam. Due to the pressure difference, the steam quickly flows to the other end of the heat pipe. At the cooler end, the steam releases heat and condenses into liquid. The liquid flows back to the heated end through the capillary action of the liquid-absorbing core 102, forming a cycle to achieve efficient heat transfer. At the same time, the pressure-bearing mechanism 101 inside the outer shell 100 ensures the pressure-bearing capacity of the heat pipe. The upper and lower ends of the support tube 10101 are connected to the outer shell 100 to provide support. The first reinforcing block 10102, the second reinforcing block 10103, and the equally spaced third reinforcing blocks 10104 further reinforce the structure. The support tube 10101 ensures uniform stress distribution on the outer side of the heat pipe, preventing localized stress concentration. The reinforcing rods 10105, inserted between the third reinforcing blocks 10104 and distributed circumferentially along the axis of the support tube 10101, form a three-dimensional support structure with the reinforcing blocks, ensuring uniform stress distribution on the pressure-bearing mechanism 101 in the circumferential direction, enhancing overall strength and rigidity, and improving the heat pipe's resistance to deformation. Furthermore, the through holes 10106 distributed circumferentially on the outer edges of the first reinforcing block 10102, the second reinforcing block 10103, and the third reinforcing block 10104 increase liquid flow channels, promote liquid circulation and heat transfer, reduce the weight of the reinforcing blocks, and lower costs. In addition, the outer side of the reinforcing blocks abuts against the inner side of the liquid-absorbing core 102, enhancing the stability of the liquid-absorbing core 102. The outer shell 100, made of brass, ensures efficient heat conduction and long-term use of the heat pipe due to its excellent thermal conductivity and corrosion resistance.
