Description

Technical Field

[0001] The present invention relates to the technical field of phase change heat exchange equipment, and more specifically, to a high-temperature heat pipe recovery device and method. Background Art

[0002] As an efficient phase change heat exchange equipment, high-temperature heat pipes have significant advantages such as high working temperature, fast heat transfer efficiency, and passivity, and show great application value in many industrial fields. In the field of energy and power, high-temperature heat pipes can effectively recover industrial waste heat, improve energy utilization efficiency, and reduce production costs; in the field of electronic heat dissipation, their fast heat transfer characteristics can timely dissipate heat, ensuring the stability and reliability of electronic devices; in the field of aerospace, high-temperature heat pipes can help aircraft adapt to extreme temperature environments and ensure flight safety. With the continuous progress of technology, the application scope of high-temperature heat pipes is still expanding, and the market demand is also increasing day by day.

[0003] When dealing with retired high-temperature heat pipes, the existing technologies mainly adopt two common methods: landfill and incineration. Landfill is to bury the retired high-temperature heat pipes underground. This treatment method is simple to operate and has low cost, without the need for complex equipment and processes. Incineration is to destroy the heat pipe structure through high-temperature incineration, hoping to decompose the substances therein, but this method requires specific incineration equipment and sites. In addition, there is also the chemical dissolution method, that is, using specific chemical solvents to dissolve the working medium in the heat pipe, but this method has high requirements for the selection and use of chemical reagents and has certain safety risks.

[0004] However, these existing treatment methods all have obvious deficiencies. Landfill not only occupies a large amount of land resources, but also the working medium in the heat pipe may seep into the soil and groundwater, causing environmental pollution. Harmful gases and residues may be generated during the incineration process, causing secondary pollution to the atmosphere and the surrounding environment. The chemical dissolution method is complex to operate, costly, and has great safety hazards. At the same time, it is also difficult to achieve efficient recovery of the working medium.

[0005] In summary, how to effectively deal with retired high-temperature heat pipes is an urgent problem for those skilled in the art at present. Summary of the Invention

This application embodiment discloses a high-temperature heat pipe recovery device and method.

[0057] The core of the present invention is to provide a high-temperature heat pipe recovery device and method.

[0058] Please refer to Figure 1 and Figure 2 .

[0059] The high-temperature heat pipe recovery device provided by the present invention includes a drilling device 2, a fixing device 3, a pressurizing device 4, a working medium recovery device 5, a cutting device, a cleaning device 7, and a drying device. The drilling device 2 is used to drill the rear end cover 11 of the heat pipe body 1, and a storage structure is arranged on the drilling device 2 for storing cleaning agents. The fixing device 3 is internally provided with a fixing fixture 31 for fixing the heat pipe body 1 and a heating component 32 for heating the heat pipe body 1. The pressurizing end of the pressurizing device 4 is communicated with the hole on the rear end cover 11 to pressurize and purge the inside of the heat pipe body 1. The working medium inlet of the working medium recovery device 5 is communicated with the front end cover joint of the heat pipe body 1 for recovering the working medium discharged from the front end cover joint of the heat pipe body 1. The cutting device (a conventional component not shown in the figure) is used to segmentally cut the heat pipe body 1 purged by the pressurizing device 4. The cleaning device 7 (as Figure 4 shown) is used to clean the residual working medium on the cut heat pipe body 1. The drying device (a conventional component not shown in the figure) is used to dry the multi-segment heat pipe body 1 cleaned by the cleaning device 7.

[0060] Specifically, the drilling device 2 drills the rear end cover 11 of the heat pipe body 1, and the cleaning agent stored in its storage structure can clean the working medium around the hole of the rear end cover 11 to avoid working medium leakage and pollution. The fixing fixture 31 in the fixing device 3 fixes the heat pipe body 1, and the heating component 32 heats the heat pipe body 1 to melt the working medium for easy discharge. The pressurizing device 4 pressurizes and purges the inside of the heat pipe body 1 through the hole on the rear end cover 11 to accelerate the discharge of the working medium from the front end cover joint to the working medium recovery device 5, realizing the effective recovery of the working medium. The cutting device segmentally cuts the purged heat pipe body 1 to reduce the volume of subsequent processing. The cleaning device 7 cleans the residual working medium on the cut heat pipe body 1 to ensure the cleanliness of the heat pipe body 1. The drying device dries the multi-segment heat pipe body 1 after cleaning to prepare for further utilization or treatment. These structures work together to make the high-temperature heat pipe recovery process efficient, environmentally friendly and orderly, and can effectively handle retired high-temperature heat pipes, reducing environmental pollution and resource waste.

[0061] It should be noted that the working medium used in the heat pipe body 1 includes metal working media such as cesium, potassium, sodium, lithium, silver or high-temperature molten salts; the structure of the heat pipe body 1 includes a thermosyphon, a metal mesh heat pipe, a microchannel heat pipe, a sintered powder heat pipe, a pulsating heat pipe, a capillary pump. The cleaning agent can be methanol, absolute ethanol, propanol, isopropanol or acetone.

[0062] The above-mentioned high-temperature heat pipe recovery device effectively solves the problems existing in the treatment process of traditional retired high-temperature heat pipes, such as environmental pollution (such as soil and groundwater pollution caused by landfilling, harmful gas and residue pollution generated by incineration), resource waste (such as resource loss caused by the inability to efficiently recover working fluids, and the failure to reuse heat pipe materials), and complex operation (such as cumbersome treatment processes and high manual operation intensity). Specifically, through the drilling device 2 for precise drilling and cleaning, the fixing device 3 ensures the stability of the heat pipe during heating and pressurization, the pressurization device 4 uses inert gas to accelerate the discharge of the working fluid, the working fluid recovery device 5 realizes the efficient recovery and storage of the working fluid, the cutting device segments the heat pipe, the cleaning device 7 thoroughly removes the residual working fluid, and the drying device finally dries the heat pipe. The entire process has a high degree of automation, is easy to operate, environmentally friendly and safe, and significantly improves the efficiency and sustainability of high-temperature heat pipe recovery.

[0063] The high-temperature heat pipe recovery device and method provided by the present invention will be introduced in more detail below with reference to the accompanying drawings and specific embodiments.

[0064] In a specific embodiment, referring to Figure 2 , the drilling device 2 includes a drilling machine 21, a storage structure is arranged on one side of the drilling machine 21, and the drill bit of the drilling machine 21 is used to drill the rear end cover 11.

[0065] Specifically, the drilling machine 21 in the drilling device 2 uses the drill bit to drill the rear end cover 11 of the heat pipe body 1. At the same time, the storage structure is arranged on one side of the drilling machine and can store cleaning agents for cleaning the working fluid around the holes of the rear end cover. Such a design enables the drilling of the rear end cover of the heat pipe body and the cleaning of the surrounding working fluid to proceed in an orderly manner, effectively avoiding the influence of residual working fluid on subsequent recovery operations, and improving the efficiency and quality of high-temperature heat pipe recovery. Cleaning agents can be used to clean the cross-section with cotton swabs to clean the working fluid around the holes of the rear end cover 11.

[0066] The drilling machine 21 can select common electric drilling machines on the market, which have the characteristics of high power and fast drilling speed, such as some industrial-grade handheld electric drilling machines. The drill bit of the drilling machine 21 usually adopts hard alloy material, which has high hardness and good wear resistance and can easily penetrate the rear end cover 11 of the heat pipe body 1.

[0067] Based on any of the above embodiments, referring to Figure 2 , the storage structure includes a cleaning agent storage box 22, and the cleaning agent storage box 22 is fixedly arranged on one side of the drilling machine 21.

[0068] Specifically, when drilling the rear end cover 11 of the heat pipe body 1, since the cleaning agent storage box 22 is fixedly arranged on one side of the drilling machine 21, the cleaning agent in the box can be taken at any time. After drilling is completed, the working medium around the holes opened in the rear end cover can be cleaned in time with a tool dipped in the cleaning agent, avoiding pollution or corrosion of equipment caused by working medium leakage, ensuring the smooth progress of the subsequent recovery process, and improving the safety and stability of the heat pipe recovery process.

[0069] The cleaning agent storage box 22 is generally made of plastic material, such as polyethylene plastic, which has good corrosion resistance and can prevent the cleaning agent from damaging it.

[0070] Based on any one of the above embodiments, referring to Figure 2 , the fixing device 3 includes a vertically arranged support frame 33, a fixing clamp 31 is arranged at one end of the top of the support frame 33, and an adjusting part is arranged on the support frame 33, and the adjusting part is used to adjust the height of the support frame 33.

[0071] Specifically, by adjusting the height of the support frame 33 through the adjusting part, the fixing clamp 31 can be in a suitable position to firmly fix the heat pipe body 1. For example, the adjusting part can drive the screw rod to rotate through a driving motor, so that the slider slides in the slide rail, thereby changing the height of the support frame, or it can be lifted and lowered through a lifting hydraulic rod or a pneumatic rod. In this way, on the one hand, it can meet the fixing requirements of heat pipe bodies 1 of different specifications and ensure the versatility of the device; on the other hand, it ensures that the heat pipe body 1 remains stable in subsequent processes such as heating and working medium recovery, which is beneficial to improving the efficiency and quality of heat pipe recovery.

[0072] The support frame 33 is generally made of high-strength steel, such as stainless steel, which has sufficient strength and stability to support the heat pipe body. The fixing clamp 31 is usually a pipe fixing clamp, such as a C-shaped clamp, which can firmly clamp the heat pipe body 1. The fixing clamp 31 is arranged at one end of the top of the support frame 33 and is fixedly connected to the support frame 33 by means of bolts or the like.

[0073] Furthermore, the adjusting part includes a slide rail 34 opened on the support frame 33 and a slider 35 slidably arranged in the slide rail 34. A screw rod 36 is rotatably arranged in the slide rail 34 along the length direction of the slide rail 34. The screw rod 36 is threadedly connected to the slider 35, and a driving motor 37 for driving the screw rod 36 to rotate is arranged on the support frame 33.

[0074] Specifically, the drive motor 37 of the adjusting part drives the screw 36 to rotate. Since the screw 36 is threadedly connected to the slider 35, the slider 35 will slide along the length direction of the slide rail 34 within the slide rail 34. This structure enables the support frame 33 to flexibly adjust its height according to actual needs, thereby facilitating the fixing fixture 31 to better fix the heat pipe body 1 and adapting to the fixing requirements of heat pipe bodies 1 of different specifications, ensuring that subsequent operations such as heating can be carried out stably and accurately.

[0075] Based on any one of the above embodiments, referring to Figure 1 , the heating assembly 32 includes a connecting rod fixedly arranged on the support frame 33 and a heating coil arranged at the end of the connecting rod away from the support frame 33.

[0076] Specifically, the heating coil of the heating assembly 32 is arranged outside the heat pipe body 1 through a connecting rod fixed on the support frame 33. When it is necessary to heat the heat pipe body 1, the heating coil is energized to generate heat, thereby causing the working fluid in the heat pipe body 1 to be heated and melted for subsequent discharge. This setting method can stably heat the heat pipe body and ensure the smooth progress of the working fluid recovery.

[0077] Based on any one of the above embodiments, referring to Figure 1 , the pressurizing device 4 includes a gas storage tank 42, a connecting pipe, and a control valve 41. The gas storage tank 42 is arranged on one side of the support frame 33. The connecting pipe is connected between the gas outlet of the gas storage tank 42 and the hole of the rear end cover 11, and the control valve 41 is arranged between the gas storage tank 42 and the connecting pipe.

[0078] Specifically, the pressurizing device 4 includes a gas storage tank 42 arranged on one side of the support frame 33, a connecting pipe connected between the gas outlet of the gas storage tank 42 and the hole of the rear end cover 11, and a control valve 41 arranged between the gas storage tank 42 and the connecting pipe. When it is necessary to pressurize and purge the heat pipe body 1, the control valve 41 is opened, and the gas in the gas storage tank 42 will enter the hole of the rear end cover 11 through the connecting pipe, thereby pressurizing and purging the heat pipe body 1. This structure can effectively accelerate the discharge of the working fluid in the heat pipe body and improve the working fluid recovery efficiency.

[0079] It should be noted that the gas in the gas storage tank 42 can be an inert gas.

[0080] Based on any one of the above embodiments, as Figures 1 to 3 shown, the working fluid recovery device 5 includes a recovery tank 53, a recovery pipe, and a liquid level gauge 56. The recovery tank 53 is arranged on one side of the support frame 33. In the recovery tank 53, a recovered working fluid 55 and an isolation liquid layer 54 are sequentially placed from the bottom of the tank. The recovery pipe is arranged at the front end cover joint of the heat pipe body 1 and extends below the isolation liquid layer 54 in the recovery tank 53, and the liquid level gauge 56 is arranged in the recovery tank 53.

[0081] Specifically, the working fluid recovery device 5 includes a recovery tank 53 located on one side of the support frame 33. Inside the recovery tank 53, a recovery working fluid 55 and an isolation liquid layer 54 are successively placed from the bottom of the tank. At the joint of the front end cover 11 of the heat pipe body 1, there is a recovery pipe extending deep below the isolation liquid layer 54 in the recovery tank 53. A liquid level gauge 56 is also provided in the recovery tank 53. During operation, the working fluid discharged from the heat pipe body 1 enters the recovery tank 53 through the recovery pipe and falls into the recovery working fluid 55 below the isolation liquid layer 54 for collection. The liquid level gauge 56 can monitor the liquid level of the recovery working fluid 55 in the recovery tank 53 to prevent the overflow of the working fluid. This structure and working method enable the effective recovery and storage of the working fluid, avoid the leakage of the working fluid, and at the same time, the recovery situation can be grasped in real time, ensuring the smooth progress of the high-temperature heat pipe recovery operation.

[0082] It should be noted that the isolation liquid layer 54 can be kerosene, paraffin or vaseline; the liquid level gauge 56 can be an electrode liquid level gauge, a magnetic float liquid level gauge or a magnetostrictive liquid level gauge.

[0083] Furthermore, a metal quick connector 51 and a working fluid isolation valve 52 are provided on the recovery pipe. The metal quick connector 51 is connected to the joint of the heat pipe body 1, and a working fluid isolation valve 52 is connected between the metal quick connector 51 and the recovery tank 53. The metal quick connector 51 is tightly connected to the joint of the heat pipe body 1, which not only ensures the tightness of the working fluid during the recovery process, prevents leakage, but also facilitates quick installation and disassembly, improving the efficiency of the recovery operation. The working fluid isolation valve 52 is connected between the metal quick connector 51 and the recovery tank 53. As a control element, it can be opened or closed as needed during the recovery process to control the flow of the working fluid. At the beginning of the recovery operation, the working fluid isolation valve 52 is opened, so that the working fluid in the heat pipe body 1 can smoothly flow into the recovery tank 53 through the metal quick connector 51. When the working fluid in the recovery tank 53 reaches a certain amount or it is necessary to stop the recovery, the working fluid isolation valve 52 can be closed, thereby cutting off the flow path of the working fluid, preventing the working fluid from continuing to flow into the recovery tank 53, and at the same time avoiding potential risks such as excessive pressure or overflow of the working fluid in the recovery tank 53.

[0084] Based on any of the above embodiments, the working fluid recovery device 5 further includes a vacuum pump 61 and a hydrogen content detector 57. The output end of the vacuum pump 61 is connected to the inside of the recovery tank 53, and the hydrogen content detector 57 is arranged on the recovery tank 53.

[0085] Specifically, a primary vacuum valve 58, a vacuum connector 59, a secondary vacuum valve 60, and a vacuum pump 61 are sequentially connected to the top of the recovery tank 53. A hydrogen content detector 57 is provided on the recovery tank 53. During operation, the hydrogen content detector 57 monitors the hydrogen content in the recovery tank 53 in real time. When it detects a high hydrogen content or a slow discharge rate of the working fluid in the heat pipe body 1, the vacuum pump is started to extract the gas in the upper part of the recovery tank 53, thereby reducing the hydrogen content and pressure in the recovery tank 53. Such a structure and working process can effectively ensure the smooth progress of the working fluid recovery, avoid affecting the working fluid recovery efficiency due to excessive hydrogen content or pressure, and improve the overall working performance and reliability of the high-temperature heat pipe recovery device.

[0086] It should be noted that the vacuum pump 61 can be a combination of a rotary vane pump, a roots pump, a molecular pump, and an ion pump, and the vacuum degree range is from 1.5 atmospheres to the order of 10-5 Pa.

[0087] Based on any of the above embodiments, the cutting device can be a cutting machine. The cleaning device 7 includes a cleaning machine 71 and a cleaning tank. The cleaning machine 71 can be an ultrasonic cleaning machine. The cleaning device 7 cleans the divided heat pipe body 1 with the cleaning agent in the cleaning tank.

[0088] Specifically, the cleaning device 7 constructs an efficient purification system with "sound-magnetic-thermal-flow" multi-physical field coupling through the collaborative innovation of the ultrasonic cleaning machine 71 and the cleaning tank: the ultrasonic cleaning machine 71 adopts 28 kHz / 132 kHz dual-frequency superposition and three-dimensional focused sound field technology, combined with the AI vision defect compensation algorithm, to achieve the targeted removal of multi-scale working fluid residues with a size of 0.1-50 μm on the inner wall of the heat pipe, and the uniformity of the cleaning intensity reaches 92%; the cleaning tank integrates a three-stage swirl jet, a nano-film filtration cycle, and a pulsed magnetic field assistance module. Through gradient heating (25-60 °C) and targeted friction of magnetic nanoparticles, the cleaning efficiency of the capillary core micropores is increased by 65%, and the service life of the cleaning agent is extended by 8 times; relying on the material-working fluid database and the on-line corrosion monitoring system, the device can adaptively match 12-dimensional cleaning parameters and dynamically inject corrosion inhibitors, and cooperate with double verification of fluorescence tracing and helium mass spectrometry leak detection to ensure that the cleanliness meets the requirements.

[0089] Based on any of the above embodiments, the drying device includes a drying box, and a drying fan is arranged in the drying box. The drying fan dries the cleaned heat pipe body 1.

[0090] The implementation principle of a high-temperature heat pipe recovery device according to an embodiment of the present application is as follows: Through the collaborative work of each device, the high-temperature heat pipe recovery device first drills and cleans the rear end cover 11 of the heat pipe body 1 using the drilling device 2, then fixes and heats the heat pipe body 1 by the fixing device 3 to melt the working medium, then the pressurizing device 4 pressurizes and purges to accelerate the discharge of the working medium, the working medium recovery device 5 recovers and monitors the working medium, then the cutting device segments the heat pipe body 1, the cleaning device 7 cleans the residual working medium, and finally the drying device dries the heat pipe body 1. The whole process is efficient and environmentally friendly. Compared with the traditional landfill, incineration and chemical dissolution methods, it not only avoids environmental pollution, but also realizes the effective recovery of the working medium and the reuse of the heat pipe body 1, improves the resource utilization rate, and reduces the production cost.

[0091] The high-temperature heat pipe recovery method provided by the present invention applies the above-mentioned high-temperature heat pipe recovery device, and the recovery method includes:

[0092] Drill the rear end cover 11 of the heat pipe body 1 through the drilling device 2, and clean the working medium around the holes of the rear end cover 11 with a cleaning agent;

[0093] Fix the heat pipe body 1 through the fixing clamp 31, and control the heating component 32 to heat the heat pipe body 1;

[0094] Pressurize the inside of the heat pipe body 1 through the pressurizing device 4, and discharge the working medium inside the heat pipe body 1 into the working medium recovery device 5;

[0095] Cut the heat pipe body 1 through the cutting device, and clean the residual working medium inside the heat pipe body 1 through the cleaning device 7;

[0096] Control the drying device to dry the cleaned heat pipe body 1.

[0097] Specifically, a hole is drilled in the rear end cap 11 of the heat pipe body 1 by the drilling device 2, and the working medium around the hole of the rear end cap 11 is cleaned with a cleaning agent. During the operation, first place the heat pipe body 1 in a suitable position, start the drilling machine 21, and align the drill bit with the rear end cap 11 to drill a hole. After drilling, take out the cleaning agent from the storage structure, dip a cotton swab or other tools in the cleaning agent and wipe around the hole of the rear end cap 11 to remove the residual working medium. The cleaning agent used here can be methanol, absolute ethanol, etc., which have good solubility and volatility and can quickly and effectively clean the working medium. The heat pipe body 1 is fixed by the fixing clamp 31, and the heating component 32 is controlled to heat the heat pipe body 1. Place the heat pipe body 1 in the fixing clamp 31, tighten the bolts of the clamp to ensure that the heat pipe body 1 is firmly fixed. Then start the heating component 32. For the induction heating coil, its heating power and time can be adjusted to make the heat pipe body 1 evenly heated and the working medium gradually melt. During the heating process, closely monitor the temperature change of the heat pipe body to avoid overheating and damaging the heat pipe body 1. The heat pipe body 1 is pressurized by the pressurizing device 4, and the working medium in the heat pipe body 1 is discharged into the working medium recovery device 5. Open the control valve 41 of the pressurizing device 4 to allow the inert gas in the gas storage tank 42 to enter the heat pipe body 1 through the connecting pipe to pressurize and purge the inside of the heat pipe body 1. Under the action of pressure and gravity, the working medium flows through the front end cap joint of the heat pipe body 1 and into the recovery tank 53 of the working medium recovery device 5 through the recovery pipe. During this process, the liquid level gauge 56 monitors the liquid level of the recovered working medium in the recovery tank 53 in real time, and the hydrogen content detector 57 detects the hydrogen content in the recovery tank 53. If the hydrogen content is high or the discharge speed of the working medium is slow, start the vacuum pump 62 to reduce the hydrogen content and pressure in the recovery tank 53 and accelerate the discharge speed of the working medium. The heat pipe body 1 is cut by the cutting device, and the residual working medium in the heat pipe body 1 is cleaned by the cleaning device 7. When the working medium in the heat pipe body 1 is basically emptied, use the cutting device 7 to cut the heat pipe body 1 into segments. Place the cut heat pipe body 1 into the cleaning tank of the cleaning device 7. The cleaning tank is filled with a cleaning agent in the tank, such as methanol, absolute ethanol, etc. Start the ultrasonic cleaning machine 71 and use the cavitation effect of ultrasonic waves to more thoroughly clean the residual working medium in the heat pipe body 1. Control the drying device to dry the cleaned heat pipe body. Place the multi-segment cleaned heat pipe body 1 into the drying oven of the drying device, start the drying fan, and dry the heat pipe body 1 through hot air circulation. During the drying process, control the temperature and time to ensure that the moisture in the heat pipe body 1 is completely removed for subsequent storage and reuse.

[0098] The above-mentioned high-temperature heat pipe recovery method operates according to a series of ordered steps, from drilling and cleaning the rear end cover 11 of the heat pipe body 1, to fixing heating, pressurizing and discharging the working medium, then to cutting, cleaning and the final drying treatment. Each step is closely coordinated to form a complete recovery process. Through this method, the working medium in the high-temperature heat pipe can be recovered efficiently and environmentally friendly. At the same time, the heat pipe body 1 is processed to achieve the effective utilization of resources, avoiding the environmental pollution and resource waste problems brought by traditional recovery methods, and having significant economic and environmental benefits.
