Description

Technical Field

[0001] This utility model relates to the field of heat pipe technology, and in particular to a heat pipe with controllable temperature. Background Technology

[0002] Temperature-controlled heat pipes, as specially designed components in the field of heat transfer, extend the temperature control function beyond that of traditional heat pipes. As a highly efficient heat transfer element, the fundamental characteristic of a heat pipe is its ability to rapidly conduct heat between its two ends. In a temperature-controlled heat pipe structure, the heat pipe is the core component, having a crucial impact on the overall performance of the heat pipe.

[0003] In the installation of common temperature-controlled heat pipe sealing assemblies, multiple bolt assemblies are typically used for fixation. This installation method has significant drawbacks in the disassembly process; unscrewing the nuts requires not only considerable torque but also appropriate specialized tools. Furthermore, the presence of multiple bolt assemblies increases the difficulty of alignment during installation, especially in complex equipment installation environments, where this alignment process is time-consuming. Moreover, the installation process involves more than just tightening the nuts; it also involves the accurate installation of the sealing seat, the correct placement of the elastic gasket and flat gasket, and other intertwined steps, further increasing the complexity and tediousness of the entire installation process. In view of the above problems, this paper proposes a temperature-controlled heat pipe. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heat pipe with controllable temperature.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A temperature-controllable heat pipe includes a heat pipe body and a sealing seat. A fixed sleeve is fixedly installed on the heat pipe body. The fixed sleeve has a first sealing groove and a second sealing groove. The sealing seat has a hollow sealing ring and a solid sealing ring. The sealing seat has a movable cavity and a rotating cavity inside. A piston plate is slidably installed in the movable cavity. A screw is rotatably installed in the rotating cavity. The piston plate is connected to the screw through a connecting mechanism. The screw is connected to the fixed sleeve through a rotating mechanism. The movable cavity and the hollow sealing ring are connected through a connecting channel. A connecting groove is provided on the surface of the sealing seat. A sliding rod is provided in the connecting groove. A connecting plate is slidably installed on the sliding rod through an elastic mechanism. A movable plate is installed on the connecting plate.

[0007] Preferably, the connecting mechanism includes a connecting frame threaded onto the screw, the connecting frame having a U-shaped design and its end fixedly connected to the piston plate.

[0008] Preferably, the rotating mechanism includes a gear mounted on a sealing seat and connected to a screw, and a gear ring is mounted on the fixed sleeve, the gear ring meshing with the gear.

[0009] Preferably, the elastic mechanism includes two springs sleeved on the outside of the slide rod, with both ends of the two springs elastically connected to the inner wall of the connecting groove and the outer wall of the movable plate, respectively.

[0010] Preferably, a positioning block is installed on the movable plate, and the positioning block is designed to correspond to the gear.

[0011] Preferably, the surface of the movable plate is provided with a rubber pad, and the surface of the rubber pad is provided with anti-slip texture.

[0012] The beneficial effects of this utility model are:

[0013] 1. By incorporating a solid sealing ring and a controllable hollow sealing ring, after installation, the hollow sealing ring expands and fits into the second sealing groove, working in conjunction with the solid sealing ring to effectively ensure the airtightness of the heat pipe body. This sealing design prevents leakage of the medium inside the pipe, ensuring stable operation of the heat pipe during work. This is particularly important for environments requiring precise temperature control, such as temperature-sensitive chemical production processes, where a good seal can maintain a stable temperature environment inside the heat pipe.

[0014] 2. During installation, the hollow sealing ring is initially in a deflated state, which facilitates the installation of the sealing seat on the fixed sleeve. Then, by rotating the sealing seat, the hollow sealing ring expands to achieve a seal. This design cleverly adapts to the installation steps and ensures that the sealing structure can function normally throughout the entire installation process.

[0015] 3. During installation, simply place the sealing seat onto the fixing sleeve and then rotate the sealing seat to achieve expansion and sealing of the hollow sealing ring. The operation is relatively simple. No complicated tools or special installation skills are required, reducing installation difficulty and cost, and improving installation efficiency.

[0016] 4. During disassembly, simply move the movable plate to release the positioning block from limiting the gear, and then reverse the sealing seat. This convenient disassembly method facilitates the maintenance and replacement of the heat pipe. For example, when the heat pipe malfunctions and needs repair or replacement, it can be quickly removed from the equipment, reducing equipment downtime. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4

[0024] A temperature-controllable heat pipe includes a heat pipe body 1 and a sealing seat 6. Other components are also provided on the heat pipe body 1 to form a temperature-controllable heat pipe. The specific structure is not disclosed in this solution. For details, please refer to the prior art.

[0025] A fixing sleeve 2 is fixedly installed on the heat pipe body 1. The fixing sleeve 2 is provided with a first sealing groove 3 and a second sealing groove 4. The sealing seat 6 is provided with a hollow sealing ring 7 and a solid sealing ring 8. The sealing seat 6 is provided with a movable cavity 9 and a rotating cavity 10. A piston plate 13 is slidably installed in the movable cavity 9. A screw 11 is rotatably installed in the rotating cavity 10. The piston plate 13 is connected to the screw 11 through a connecting mechanism. The screw 11 is connected to the fixing sleeve 2 through a rotating mechanism. The movable cavity 9 and the hollow sealing ring 7 are connected through a connecting channel 15. There is gas between the piston plate 13, the connecting channel 15 and the internal space of the hollow sealing ring 7. As the piston plate 13 moves and pushes the gas, the state of the hollow sealing ring 7 can be changed, making it either deflated or full.

[0026] The sealing seat 6 has a connecting groove 16 on its surface, a sliding rod 18 is provided in the connecting groove 16, a connecting plate 17 is slidably sleeved on the sliding rod 18 through an elastic mechanism, and a movable plate 19 is installed on the connecting plate 17.

[0027] The connecting mechanism includes a connecting frame 14 threaded onto the screw 11. The connecting frame 14 has a U-shaped design and its end is fixedly connected to the piston plate 13. Part of the connecting frame 14 slides through the inner wall of the rotating cavity 10 and extends into the movable cavity 9, thus it has its own limit and will not rotate with the screw 11.

[0028] The rotating mechanism includes a gear 12 mounted on the sealing seat 6 and connected to the screw 11, and a gear ring 5 mounted on the fixed sleeve 2, which meshes with the gear 12. By relying on the gear ring 5 and the gear 12, the screw 11 can rotate synchronously when the sealing seat 6 rotates relative to the heat pipe body 1.

[0029] The elastic mechanism includes two springs sleeved on the outside of the slide rod 18, with both ends of the springs elastically connected to the inner wall of the connecting groove 16 and the outer wall of the movable plate 19, respectively. The elastic potential energy provided by the springs enables the stable operation of the movable plate 19, ensuring that it can block the connecting groove 16 when no external force is involved.

[0030] A positioning block 20 is installed on the movable plate 19, and the positioning block 20 is designed to correspond to the gear 12. When the positioning block 20 is between two adjacent teeth of the gear 12, the gear 12 cannot rotate, and the sealing seat 6 also cannot rotate relative to the heat pipe body 1.

[0031] The surface of the movable plate 19 is provided with a rubber pad, and the surface of the rubber pad is provided with anti-slip texture. The rubber pad and anti-slip texture are both for the convenience of the operator to move it, thereby causing the positioning block 20 to disengage from the gear 12 and be in contact with the limit position.

[0032] When using this invention, the movable plate 19 is moved to move the positioning block 20 away from the gear 12, and the piston plate 13 is positioned in the movable cavity 9 near the screw 11. The gas is mainly in the movable cavity 9 and the connecting channel 15, and the hollow sealing ring 7 is in a deflated state. At this time, the sealing seat 6 is installed on the fixed sleeve 2, and the solid sealing ring 8 is in the first sealing groove 3. The hollow sealing ring 7 corresponds to the second sealing groove 4, and the gear 12 is meshing with the gear ring 5. At this time, the sealing seat 6 is rotated relative to the heat pipe body 1, and the gear 12 is in the gear ring 5. The rotation of the screw 11 under the action of the screw 11 can drive the screw 11 to rotate. When the screw 11 rotates, the piston plate 13 moves away from the screw 11 and sends the gas into the hollow sealing ring 7, causing it to expand and fit into the second sealing groove 4. At this time, under the action of the hollow sealing ring 7 and the solid sealing ring 8, the sealing performance of the heat pipe body 1 is guaranteed. Then the movable plate 19 is released, and under the action of the spring, it moves to drive the positioning block 20 to engage in the area between the adjacent teeth of the gear 12, thereby limiting the gear 12. At this time, the sealing seat 6 cannot rotate relative to the heat pipe body 1 and cannot disengage from it.

[0033] During disassembly, move the movable plate 19 to move the positioning block 20 to release the limit, and then reverse the sealing seat 6.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
