[0042] The following is a detailed description of a process method for a space application copper-water heat pipe provided in an embodiment of the present application.

[0043] Reference Figure 1 As shown, it is a schematic diagram of a process method of a space application copper-water heat pipe provided by an embodiment of the present application. The exemplary steps of the embodiment of the present application are described below:

[0044] S101, obtaining a manufacturing process flow, manufacturing process parameters and test index parameters determined based on application scenario parameters of the copper-water heat pipe for space applications and outer dimension parameters of the heat pipe.

[0045] In the implementation mode of the present application, the application scenario parameters are used to characterize the working environment of the copper-water heat pipe for space application to be manufactured; taking the application scenario as an aircraft, the application scenario parameters may include the orbit altitude (such as 500km to 36,000km), the launch vibration environment, the heat transfer working temperature (30℃ to 90℃), the orbit storage temperature (such as -40℃ to +90℃), the ground environment of the application scenario (humidity, mold, salt spray, etc.), the use space position (inside or outside the satellite cabin), etc. The heat pipe external dimensions are used to describe the shape (round tube, flattened tube, bent tube, etc.) and size (heat pipe diameter, heat pipe length, heat pipe flattening thickness, heat pipe bending radius, etc.) of the copper-water heat pipe for space application to be manufactured. The test index parameters refer to the performance parameters that the space application copper water heat pipe to be manufactured needs to achieve, which may include the corresponding index parameters of heat transfer performance (such as the maximum heat transfer capacity Qmax ≥ 40W of a 5mm diameter round tube, Qmax ≥ 16W of a 5mm diameter flattened tube; Qmax ≥ 50W of a 6mm diameter round tube, Qmax ≥ 32W of a 6mm diameter flattened tube; Qmax ≥ 65W of a 8mm diameter round tube, Qmax ≥ 38W of a 8mm diameter flattened tube), the corresponding index parameters of anti-gravity operation capability (such as hydraulic climbing height not less than 250mm), static freeze-thaw cycle Corresponding index parameters (such as meeting the index requirements that the heat transfer performance change is less than 10% after 1000 cycles and there is no obvious change in appearance), corresponding index parameters for working freeze-thaw cycles (such as meeting the index requirements that the heat transfer performance change is less than 10% after 1000 cycles and there is no obvious change in appearance), corresponding index parameters for startup performance (such as meeting the first-level derating requirements for the controlled chip temperature, the maximum working section temperature ≤85℃), corresponding index parameters for accelerated life (such as not less than 7 years), corresponding index parameters for burst strength (such as meeting the requirement that the burst pressure is greater than or equal to 2 times the maximum working pressure), corresponding index parameters for sinusoidal vibration and corresponding index parameters for random vibration, etc.

[0046] Among them, the manufacturing process parameters are used to control the manufacturing process flow so that the manufactured copper-water heat pipe for space applications can work under the application scenario corresponding to the application scenario parameters, and meet the requirements of the heat pipe external dimension parameters and the test index parameters; the manufacturing process parameters include one or more of the sintering process parameters, the degassing process parameters and the filling working fluid process parameters.

[0047] S102, manufacturing a space application copper water heat pipe according to the manufacturing process and manufacturing process parameters.

[0048] In the implementation manner of the present application, the manufacturing process includes, in sequence, an incoming material inspection process, a tube cutting process, a cleaning and drying process, a necking process, a sintering process, a correction process, a sealing process (large mouth), an inspection process, an annealing process, a degassing process, a filling process, a sealing process (small mouth), a molding process, a temperature resistance test process, a quality loss process, a thermal performance test process, an environmental test process, a thermal performance retest process, and a final inspection process.

[0049] Incoming material inspection process: After the purchased copper tube arrives, use a vernier caliper to check whether the diameter of the copper tube (i.e. the heat pipe diameter) and the wall thickness of the copper tube (i.e. the heat pipe thickness) meet the requirements; check whether the composition of the copper tube meets the corresponding requirements; use instruments to test the purity of water to see whether it meets the corresponding requirements.

[0050] Tube cutting process: When starting the tube cutting machine, first check whether the process parameters meet the requirements, adjust the tube cutting machine equipment, select the copper tube according to the outer size parameters of the heat pipe, fill the V-groove of the tube cutting machine, align the cut tube end slightly, and open the tube cutting machine to cut the tube.

[0051] Cleaning and drying process: After cutting, the copper tube is washed with acid and alkali to remove the residual milling fluid and other impurities on the heat pipe. After cleaning, put it into the drying box, bake it for half an hour, and take it out after drying.

[0052] Shrinking process: After adjusting the shrinking machine equipment, put the cleaned and dried copper tube into the hopper; turn on the power switch of the operation panel, set the corresponding shrinking parameters and shrink the copper tube to be shrunken; check whether the length of the heat pipe after shrinking meets the outer dimensions of the heat pipe; if yes, proceed to the next process.

[0053] Sintering process: sintering process parameters include copper powder size, weight ratio between copper powders of each copper powder size, and wick parameters; then a copper-water heat pipe for space application is manufactured according to the manufacturing process flow and the manufacturing process parameters, including: if the current manufacturing process is the sintering process in the manufacturing process flow, the center rod after drying and cleaning is inserted into the copper tube to be sintered; the copper powders of each copper powder size are mixed according to the weight ratio; the mixed copper powder is filled into the copper tube after the center rod is inserted; the copper tube filled with copper powder is inserted into the graphite carrier; and the bell jar and the graphite carrier are locked to keep airtight and then pushed into the sintering furnace, and the copper tube filled with copper powder is sintered according to the sintering procedure corresponding to the wick parameters (such as wick thickness, wick porosity, wick permeability, wick pore size, etc.) so that the sintered copper tube meets the requirements of the wick parameters; after sintering, the bell jar is pushed to the cooling zone for cooling, and the center rod in the cooled copper tube is pulled out and placed in the material box.

[0054] Correction process: If the outer diameter of the copper tube to be corrected meets the external dimensions of the heat pipe, adjust the interval of the straightening machine and place the copper tube to be corrected on the straightening machine for straightening; check the flatness of the tube-rolling splint to see if there are any impurities remaining; if no impurities are left, place the straightened copper tube on the tube-rolling splint for tube-rolling correction; if there are impurities, after removing the impurities, place the straightened copper tube on the tube-rolling splint for tube-rolling correction.

[0055] Sealing process (large mouth): After adjusting the sealing machine equipment, install the corresponding sealing mold; place the shrinking section of the copper tube to be sealed on the pusher with the shrinking mold facing the shrinking mold; open the sealing machine equipment to shrink the mouth, and after the shrinking is completed, use the spot welder to weld and seal.

[0056] Leak detection process: Check whether there is any leakage in the heat pipe after welding and sealing; if there is any leakage, re-weld it; if there is no leakage, proceed to the next process.

[0057] Annealing process: The annealing process can reduce the hardness of the material due to work hardening, making the heat pipe material easier to process and form.

[0058] Degassing process: After adjusting the degassing machine equipment, turn on the power switch, vacuum pump switch and oil pressure switch in sequence; make the vacuum gauge below 0.1pa, set the heat pipe degassing time and vacuum degree, and then start degassing the copper pipe to be degassed. Specifically, the degassing process parameters include degassing temperature, degassing vacuum degree, flushing pressure and replacement times; according to the manufacturing process flow and the manufacturing process parameters, the copper-water heat pipe for space application is manufactured, including: if the current manufacturing process is the degassing process in the manufacturing process flow, the copper pipe to be degassed will be heated and degassed according to the degassing temperature; the copper pipe to be degassed will be degassed at a reduced pressure according to the degassing vacuum degree; the copper pipe to be degassed will be replaced and degassed according to the flushing pressure and replacement times.

[0059] Here, temperature increase degassing: by increasing the temperature, the non-condensable gas contained in and adsorbed inside the metal and porous materials is removed. Pressure reduction degassing: by reducing the pressure, the non-condensable gas contained in and adsorbed inside the metal and porous materials is removed. Displacement degassing: by flushing and replacing with a working fluid, the non-condensable gas contained in and adsorbed inside the metal and porous materials is removed. The present application adopts a process method combining the above three methods for degassing. After the degassing process test, the composition of the working fluid after degassing is detected to obtain the optimized process parameters. Then, according to the optimized process parameters, the copper-water heat pipe product is developed, and an accelerated life test is carried out to determine whether the process parameters can meet the requirements of product performance, life and reliability. Finally, the process flow and process parameters are confirmed and solidified.

[0060] Filling working fluid process: First check whether the process filling working fluid parameters meet the requirements. Use a caliper to measure the outer diameter and length of the copper tube to be filled with the working fluid, and check whether the copper tube to be filled with the working fluid meets the external dimensions of the heat pipe; if it does, determine whether there is any blockage at the injection port, and confirm that the injection tube is not deformed before starting the filling. Specifically, the filling working fluid process parameters include the opening adjustment range of the flow meter regulating valve, the flow meter adjustment accuracy, the pipeline length, the pipe diameter, the relationship between the mass change value and the opening range; the space application copper-water heat pipe is manufactured according to the manufacturing process and the manufacturing process parameters, including: if the current manufacturing process is the filling working fluid process in the manufacturing process, the working fluid to be filled in the heat pipe is charged according to the opening adjustment range of the flow meter regulating valve, the flow meter adjustment accuracy, the pipeline length, the pipe diameter, the relationship between the mass change value and the opening range.

[0061] In the implementation manner of the present application, a flow meter corresponding to the flow meter adjustment accuracy is used to measure the filling flow, and the opening of the flow meter regulating valve is adjusted based on the opening adjustment range of the flow meter regulating valve to ensure that the flow during the filling process is controllable and accurately measured.

[0062] Sealing process (small mouth): Place the heat pipe filled with working fluid on the automatic welding machine, set the parameters of the sealing machine, and then weld and seal it.

[0063] Forming process: the straight tubes after the sealing process (small mouth) are classified, the bent tubes are bent with an automatic bending machine, and the flat tubes are flattened and formed with corresponding molds.

[0064] Temperature resistance process: The welded heat pipe is subjected to a temperature resistance test to check whether there is any leakage during the welding of the heat pipe.

[0065] Quality damage process: Use a high-precision electronic scale to measure the heat pipe and check whether it has leakage.

[0066] Thermal performance testing process: Adjust the machine equipment, conduct temperature difference and power tests on the formed heat pipes, and detect heat pipes with poor performance.

[0067] Environmental testing process: For heat pipes that pass the performance test, wet heat and chemical resistance tests are carried out to detect whether the performance of the heat pipes meets the requirements under specific conditions.

[0068] Thermal performance retest process: After the environmental test of the heat pipe is completed, the temperature difference and power are retested to ensure the performance of the heat pipe is good.

[0069] Final inspection process: inspect the appearance and size of the inspected heat pipes, and pack and ship them out if there are no problems.

[0070] Here, the present application strictly controls each process through sintering process parameters, degassing process parameters and filling working fluid process parameters, so that the manufactured copper-water heat pipe for space applications meets the corresponding index parameters of heat transfer performance, the corresponding index parameters of anti-gravity operation capability, the corresponding index parameters of static freeze-thaw cycle, the corresponding index parameters of working freeze-thaw cycle, the corresponding index parameters of starting performance, the corresponding index parameters of accelerated life, the corresponding index parameters of blasting strength, the corresponding index parameters of sinusoidal vibration and the corresponding index parameters of random vibration, etc.

[0072] In the implementation manner of the present application, one or more tests of freeze-thaw and mechanical environment test, pressure test and accelerated life test are performed on the manufactured copper-water heat pipe for space application based on the test index parameters; and the copper-water heat pipe for space application that passes the test is determined as the target copper-water heat pipe for space application.

[0073] Here, since the working environment of copper-water heat pipes for space applications is more extreme, it is necessary to conduct one or more tests of freeze-thaw and mechanical environment tests, pressure tests and accelerated life tests on the copper-water heat pipes for space applications to ensure the quality of the copper-water heat pipes for space applications.
