[0001] The utility model relates to the technical field of heat pipes, in particular to a laser-etched wick. Background Technique
[0002] A laser etching machine is a device that uses a high-energy laser beam to etch, cut, engrave, mark, etc. the surface of materials. It mainly consists of a laser, a beam control system, a workbench, and other auxiliary systems, and is widely used in manufacturing, scientific research, art, and cultural heritage protection, etc.
[0003] When the wick is being manufactured, the laser etching machine plays a key role. The wick mainly uses surface tension and capillary action to adsorb liquid to the surface of the core. Its two ends are in a completely closed state. When one end of the wick is heated, the liquid in the wick will vaporize and absorb heat, and then the vapor will run along the heat pipe to the other end.
[0004] Through long-term observation, although the existing wick can effectively promote heat transfer inside the heat pipe, after the heat pipe wick is used for a long time, as the temperature rises, both the liquid and solid materials in the wick will undergo thermal expansion, resulting in deformation of the heat pipe material. Minor deformation is difficult to observe, and if not replaced in time, it will easily affect its heat transfer efficiency. Therefore, a laser-etched wick is proposed for the above problems. Content of the Utility Model
[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background technique, the utility model proposes a laser-etched wick.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] As Figures 1-4 shown, a laser-etched wick includes a heat pipe 1; the inner wall of the heat pipe 1 is fixedly connected with a main body of the wick 11; two groups of brackets 12 are fixedly connected to the top of the heat pipe 1; a fixed rod 13 is fixedly connected to the middle of the bracket 12; multiple groups of fixing pieces 14 are fixedly connected to the middle of the fixed rod 13; multiple groups of top pieces 15 are slidably connected to the inner wall of the fixing piece 14, and the bottom of the top piece 15 is in contact with the middle of the heat pipe 1; during operation, after the staff installs the main body of the wick 11 on the inner wall of the heat pipe 1 and makes them closely attached for a continuous period of time and places the whole horizontally, then when the heat pipe 1 is operating, the main body of the wick 11 will conduct heat to the heat pipe 1. By providing multiple groups of fixing pieces 14 at the top of the heat pipe 1 and clamping an appropriate amount of top pieces 15 on the inner wall of the fixing piece 14, before clamping the top piece 15 on the inner wall of the fixing piece 14, the staff can apply an appropriate amount of bright-colored pigment to the middle of the top piece 15 with the help of tools, so that when the top piece 15 is placed on the inner wall of the fixing piece 14, the pigment is completely blocked by the fixing piece 14. When the heat pipe 1 is deformed and bulged after long-term use, the middle of the heat pipe 1 will push the whole top piece 15 upward, and observe whether the applied pigment appears outside. This step, combined with the set top piece 15 and the pigment applied in the middle, can facilitate the staff to observe whether the top piece 15 moves during placement, thereby judging whether the middle of the heat pipe 1 is deformed and bulged, reducing the problem that it is difficult for the staff to directly observe with the naked eye after the original heat pipe 1 has a slight deformation, resulting in the failure to replace it in time and affecting its heat transfer efficiency.
[0025] As Figure 2 and 4As shown, a liquid inlet 2 is provided at the top of the top piece 15, and the middle part of the liquid inlet 2 is arranged in a horn shape; a plurality of groups of holes 21 are provided in the middle of the top piece 15; a plurality of support rods 22 are fixedly connected to the bottom of the fixing piece 14; a sealing gasket 23 is fixedly connected to the end of the support rod 22, and the sealing gasket 23 is arranged close to the plurality of groups of holes 21; during operation, by providing the liquid inlet 2 at the top of the top piece 15, after the top piece 15 is stuck on the inner wall of the fixing piece 14, the staff can inject an appropriate amount of coolant into the top piece 15 through the liquid inlet 2. When the middle part of the heat pipe 1 is deformed and the whole top piece 15 is jacked up, the holes 21 in the middle of the top piece 15 will gradually separate from the sealing gasket 23. After losing the supporting force of the sealing gasket 23 on the liquid, the liquid inside the top piece 15 will flow out to the outside in sequence along the plurality of holes 21 and be transferred to the surface of the heat pipe 1. This step, combined with the provided holes 21, can further improve the accuracy of the staff observing whether the middle part of the heat pipe 1 is deformed. At the same time, the discharged part of the coolant can cool the surface of the heat pipe 1, reducing the problem of secondary damage caused by the heat pipe 1 being deformed due to overheating and not being cooled in time, and reducing the trouble for the subsequent staff to maintain the heat pipe 1.
[0026] As Figure 3 shown, a frame plate 3 is rotatably connected to the top of the top piece 15; an observation window 31 is fixedly connected to the inner wall of the frame plate 3; a buckle 32 is provided in the middle of the frame plate 3; during operation, by providing the frame plate 3 in the middle of the top piece 15, after the top piece 15 is stuck on the inner wall of the fixing piece 14, the staff can hold the middle part of the buckle 32 and rotate the frame plate 3 to make the observation window 31 fixed on the top of the liquid inlet 2. This step, combined with the transparent observation window 31, can improve the convenience of the staff observing the liquid level inside the top piece 15 subsequently. At the same time, it can reduce the problem that some impurities enter the top piece 15 through the liquid inlet 2 and cause blockage of the plurality of holes 21. Combined with the rotatable frame plate 3, it can improve the flexibility of the observation window 31 during operation.
[0027] As Figure 3 and 5 shown, a spring 4 is fixedly connected to the inner wall of the top piece 15; a receiving piece 41 is fixedly connected to the top of the spring 4; a rotating bead 42 is rotatably connected to the inner wall of the receiving piece 41, and the rotating bead 42 is arranged in a shape matching with the buckle 32; during operation, by providing the rotating bead 42 in the middle of the top piece 15, when rotating the observation window 31 for movement, its bottom will gradually approach and contact the rotating bead 42, and then will squeeze the rotating bead 42 downward, causing the middle length of the spring 4 to shorten. When the rotating bead 42 reaches the position of the buckle 32, under the action of the elastic force, it can be pulled to the inner wall of the buckle 32 and fix the position of the frame plate 3. This step, combined with the provided rotating bead 42, can improve the stability of the observation window 31 during operation, reducing the problem that the middle part of the frame plate 3 becomes loose due to wear after long-term use, resulting in the shaking of the observation window 31.
[0028] As Figure 5 shown, a telescopic rod 5 is fixedly connected to the inner wall of the top piece 15, and the output end of the telescopic rod 5 is fixedly connected to the bottom wall of the storage piece 41; the telescopic rod 5 is arranged inside the spring 4; during operation, by arranging the telescopic rod 5 in the middle of the top piece 15, when the spring 4 retracts, the telescopic rod 5 will be driven to move synchronously, and the telescopic rod 5 can support and limit the position of the spring 4. This step in cooperation with the arranged telescopic rod 5 can improve the stability of the spring 4 during operation and reduce the problem of bending and dislocation.
[0029] As Figure 3 shown, a filter screen 6 is fixedly connected to the inner wall of the liquid inlet 2; during operation, by arranging the filter screen 6 on the inner wall of the liquid inlet 2, when the staff pours the external coolant into the top piece 15, the filter screen 6 will filter the liquid. This step in cooperation with the arranged filter screen 6 can improve the cleanliness of the liquid poured into the top piece 15, reduce the accumulation of some fine impurities, and prevent the holes 21 from being blocked.
[0030] As Figure 5 shown, a friction pad 7 is fixedly connected to the middle of the rotating bead 42, and the friction pad 7 is arc-shaped; during operation, by arranging the friction pad 7 in the middle of the rotating bead 42, when the friction pad 7 contacts the middle of the frame plate 3, under the action of the soft material friction pad 7, the two groups can be in deep contact. This step in cooperation with the arranged friction pad 7 can improve the stability of the rotating bead 42 rotating at the bottom of the frame plate 3, further reduce the wear on the middle of the observation window 31, and at the same time improve the stability of the rotating bead 42 stuck inside the buckle 32.
[0031] Working principle: After installing the wick body 11 on the inner wall of the heat pipe 1 and making them closely attached together for a continuous period of time, the whole is placed horizontally. Subsequently, when the heat pipe 1 is working, the wick body 11 will conduct heat to the heat pipe 1. By arranging multiple sets of fixing parts 14 at the top of the heat pipe 1 and clamping an appropriate amount of top parts 15 on the inner wall of the fixing parts 14. Before clamping the top part 15 on the inner wall of the fixing part 14, the staff can apply an appropriate amount of bright-colored pigment to the middle of the top part 15 with the help of tools, so that when the top part 15 is placed on the inner wall of the fixing part 14, the pigment is completely blocked by the fixing part 14. When the heat pipe 1 is deformed and bulged after long-term use, the middle part of the heat pipe 1 will push the whole top part 15 upward, and observe whether the applied pigment appears outside. By opening a liquid inlet 2 at the top of the top part 15, after the top part 15 is clamped on the inner wall of the fixing part 14, the staff can inject an appropriate amount of coolant into the top part 15 through the liquid inlet 2. When the middle part of the heat pipe 1 is deformed and pushes the whole top part 15 upward, the holes 21 in the middle of the top part 15 will gradually separate from the gasket 23. After losing the supporting force of the gasket 23 on the liquid, the liquid inside the top part 15 will flow out to the outside in sequence along multiple holes 21 and transfer to the surface of the heat pipe 1. By arranging a frame plate 3 in the middle of the top part 15, after the top part 15 is clamped on the inner wall of the fixing part 14, the staff can hold the middle part of the buckle 32 and rotate the frame plate 3, so that the observation window 31 is fixed on the top of the liquid inlet 2. By arranging a rotating bead 42 in the middle of the top part 15, when rotating the observation window 31 to move, its bottom will gradually approach and contact the rotating bead 42, and then press down the rotating bead 42, so that the middle length of the spring 4 is shortened. When the rotating bead 42 reaches the position of the buckle 32, under the action of the elastic force, it can be pulled on the inner wall of the buckle 32 and fix the position of the frame plate 3. By arranging a telescopic rod 5 in the middle of the top part 15, when the spring 4 retracts, it will synchronously drive the telescopic rod 5 to move, and the telescopic rod 5 can support and limit the position of the spring 4. By arranging a filter screen 6 on the inner wall of the liquid inlet 2, when the staff pours the external coolant into the top part 15, the filter screen 6 will filter the liquid. By arranging a friction pad 7 in the middle of the rotating bead 42, when the friction pad 7 contacts the middle part of the frame plate 3, under the action of the soft material friction pad 7, the two groups can be in deep contact.
