[0002] A gravity axial heat pipe is a highly efficient heat transfer device whose working principle mainly relies on the phase change cycle of the working fluid and the action of gravity. This type of heat pipe is usually composed of a tube shell, a working fluid and an internal structure. Its core feature is that it uses gravity to help the condensed liquid return to the evaporation section, thereby achieving efficient heat transfer.

Furthermore, if a straight heat pipe needs to be bent to accommodate the installation space, this physical deformation often damages the carefully designed capillary structure or fluid circulation path within the heat pipe, significantly reducing its thermal conductivity or even rendering it ineffective. Consequently, existing heat pipes face significant technical limitations in terms of length adaptability and installation flexibility. Summary of the Invention

Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0025] Reference Figures 1-6 This embodiment provides a gravity axial heat pipe, including a heat conducting part 1, on which a connecting part 2 is provided, and a locking part 3 is provided inside the connecting part 2; the locking part 3 includes a locking member 31 and a bending member 32; the locking member 31 is used to lock the connecting part 2 to connect the two heat conducting parts 1 together; the setting of the bending member 32 is used to control the connection direction of the two heat conducting parts 1 to adapt to the working environment.

[0026] Among them, the heat conducting part 1 is set to realize rapid heat transfer under extremely small temperature difference, and thus realize rapid temperature transfer. The connecting part 2 is set to connect the two heat conducting parts 1 together, thereby realizing the adjustment of the heat pipe length and facilitating the installation of the equipment.

[0027] In addition, the locking portion 3 is used to lock the connecting portion 2 so that the heat pipe is connected. The internal locking part 31 controls the connecting portion 2 to lock the heat conducting portion 1. The bending part 32 is used to facilitate the adjustment of the connection angle between the two heat pipes, so that the angle adjustment can be completed without bending the heat pipe body 213, thereby preventing the situation where the heat conduction efficiency is affected by physical bending.

[0028] In summary: the two heat-conducting parts 1 are connected together through the setting of the connecting part 2, and then locked by the locking part 31, so as to complete the connection and fixation between the two, realize the length adjustment of the heat pipe, and facilitate the adjustment of the length of the heat pipe. When bending is required to adapt to the working environment, the angle between the two heat pipes can be adjusted by the bending part 32.

[0029] Reference Figure 2-Figure 6 As an optional embodiment, a gravity axial heat pipe is provided, including a connecting portion 2 including a connecting piece 21, which includes a connecting pipe 211, a bending head 212 arranged on the connecting pipe 211, and a heat pipe body 213 arranged inside the bending head 212.

[0030] Among them, the connecting tube 211 is used to install two bending heads 212, so that the bending heads 212 can rotate thereon, thereby completing the angle adjustment between the two heat pipe bodies 213, so that it adapts to the working environment. The bending head 212 is used to connect the two heat pipe bodies 213.

[0031] Preferably, the two heat pipe bodies 213 are installed at the upper and lower ends of the connecting pipe 211 through two bending heads 212, thereby realizing the splicing of the heat pipe bodies 213, thereby completing the adjustment of the length of the heat pipe bodies 213, and then the angle between the two heat pipes is adjusted by rotating the bending head 212.

[0032] Furthermore, two bending heads 212 are provided, which are respectively provided at the upper and lower ends of the connecting pipe 211 .

[0033] Furthermore, an inclined surface 214 is provided at the contact point between the bending head 212 and the connecting pipe 211 , and the angle between the inclined surface 214 and the vertical direction is in the range of 45°-90°.

[0034] The angle between the inclined surface 214 and the vertical direction ranges from 45° to 90°. This arrangement allows the angle between the two heat pipe bodies 213 to be between 90 degrees and 180 degrees when a bending head 212 is rotated, thereby facilitating angle adjustment.

[0035] Furthermore, the connecting portion 2 further includes a limiting member 22 , which includes a limiting block 221 disposed inside the bending head 212 and a limiting groove 222 disposed on the heat pipe body 213 .

[0036] The limiting block 221 is fixedly connected to the inner wall of the bending head 212 , and the limiting groove 222 is provided to adapt to the limiting block 221 so that after the heat pipe body 213 is inserted into the bending head 212 , the heat pipe body 213 will not rotate.

[0037] Furthermore, the locking member 31 includes an arcuate groove 311 provided inside the bending head 212 , a locking block 312 disposed inside the arcuate groove 311 , a locking spring 313 disposed inside the arcuate groove 311 , and a bent groove 314 disposed on the heat pipe body 213 .

[0038] The arc-shaped groove 311 is provided to facilitate the sliding of the locking block 312 inside. The locking spring 313 is provided to push the locking block 312 so that when no force is applied, the locking block 312 is located at one end of the arc-shaped groove 311. When the heat pipe body 213 is inserted into the bending head 212, the locking block 312 can smoothly enter the bending groove 314.

[0039] In addition, the bend groove 314 is opened on the outside of the heat pipe body 213 and is bent in the middle. When locking is required, it is only necessary to control the locking block 312 so that it cannot rotate, and the heat pipe body 213 can be locked with the cooperation of the lower side of the bend groove 314.

[0040] Preferably, the heat pipe body 213 is inserted into the interior of the bending head 212 by aligning the limiting groove 222 with the limiting block 221, and the heat pipe body 213 is fixed by cooperating with the bending groove 314 through the locking block 312. When locking, it is only necessary to limit the locking block 312 to complete the locking of the heat pipe body 213, thereby achieving a quick connection effect.

[0041] Furthermore, the locking portion 3 also includes a blocking member 33, which includes a control ring 331 arranged on the outside of the bending head 212, a control spring 332 arranged on the control ring 331, a blocking groove 333 arranged inside the bending head 212, and a blocking block 334 arranged inside the blocking groove 333.

[0042] Among them, the control ring 331 is slidably connected to the outer wall of the bending head 212, so that it can slide up and down, and at the same time can drive the blocking block 334 to slide up and down. The control spring 332 is fixedly connected to the outer wall of the control ring 331, and is used to push the control ring 331 so that it is always on the other side without interference. The blocking groove 333 is set to facilitate the sliding of the blocking block 334 inside, and the blocking block 334 is set to block the locking block 312, thereby facilitating the locking of the heat pipe.

[0043] In summary: by aligning the limiting groove 222 on the heat pipe body 213 with the limiting block 221 inside the bending head 212 and inserting it inside, the connection between the heat pipe body 213 and the bending head 212 is completed, and at the same time, the control ring 331 is pulled upward, so that the control ring 331 drives the blocking block 334 to move upward. When the heat pipe body 213 is inserted, the bending groove 314 drives the locking block 312 to move. When the locking block 312 moves to the appropriate position, the control ring 331 is released, so that the blocking block 334 controls the locking block 312, making it unable to reset, thereby completing the fixation of the heat pipe body 213.

[0044] Reference Figures 1-4 As an optional embodiment, a gravity axial heat pipe is provided, including a bending part 32 including a connecting groove 321 opened on the inclined surface 214, a connecting rod 322 arranged inside the connecting groove 321, and a bending spring 323 arranged on the connecting rod 322.

[0045] Among them, the connecting groove 321 is set to install the connecting rod 322, wherein the connecting rod 322 is fixed at the end of the connecting tube 211, the connecting rod 322 is set to install the bending head 212 at the end of the connecting tube 211, and the bending spring 323 is set to push the bending head 212 so that it is close to the connecting tube 211.

[0046] Furthermore, the bending member 32 further includes a positioning bead 324 provided on the bending head 212 and a positioning groove 325 provided at the end of the connecting tube 211 .

[0047] Among them, the positioning bead 324 is fixedly connected to the inclined surface 214 of the bending head 212. The positioning bead 324 is set to cooperate with the positioning groove 325 to position the bending head 212, so that its rotation angle is fixed. After rotation, it can only be fixed at 180 degrees to complete the bending.

[0048] Furthermore, the heat conducting part 1 includes a cavity arranged inside the heat pipe, a liquid wick arranged on the inner wall of the cavity, and a heat transfer fluid arranged inside the cavity.

[0049] Among them, the cavity is used to place the wick and heat transfer fluid. The wick uses capillary force to send the condensed liquid working medium from the condensation end back to the evaporation end to form a cycle. The heat transfer fluid is divided into multiple parts. Among them, the heat transfer fluid in low-temperature heat pipes is usually water, ethanol, acetone, etc.; the heat transfer fluid in medium-temperature heat pipes is usually thermal conductivity and biphenyl, etc.; the heat transfer fluid in high-temperature heat pipes is usually liquid metal, such as sodium, potassium, lithium, etc.

[0050] In summary: by aligning the limiting groove 222 on the heat pipe body 213 with the limiting block 221 inside the bending head 212 and inserting it inside, the connection between the heat pipe body 213 and the bending head 212 is completed, and at the same time, the control ring 331 is pulled upward, so that the control ring 331 drives the blocking block 334 to move upward. When the heat pipe body 213 is inserted, the bending groove 314 drives the locking block 312 to move. When the locking block 312 moves to the appropriate position, the control ring 331 is released, so that the blocking block 334 controls the locking block 312, making it unable to reset, thereby completing the fixation of the heat pipe body 213. When bending, you only need to pull the bending head 212 and then rotate it 180 degrees so that the two positioning beads 324 swap positions to complete the bending, so that the equipment can quickly adjust the length and angle.

[0051] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
