Abstract
Description
Technical Field
[0001] This application relates primarily to the field of heat pipe micropile technology, and more particularly to a heat pipe detection device. Background Technology
[0002] A heat pipe microreactor is a new type of nuclear reactor. It achieves core heat transfer through high-temperature heat pipes. The high-temperature heat pipes are vacuum-sealed bodies (vacuum degree 10⁻² to 10⁻⁶ mmHg), containing a certain amount of working fluid, and their inner surface is lined with porous capillary wicks.
[0003] Currently, the manufacturing of high-temperature heat pipes faces two major bottlenecks: First, the forming and assembly of the wick cannot completely avoid the problem of excessively large local gaps. Specifically, during iterative research, it was found that the gap between the wick and the pipe wall has a critical impact on the heat pipe's overheating failure during startup; even a gap of a few hundred micrometers can cause a huge deviation in heat pipe performance. Second, there is a lack of quality monitoring methods. Existing technologies can only verify performance through final heating and performance testing, and cannot immediately assess quality after wick assembly. This results in a single verification requiring a complete manufacturing process, extending the research and development iteration cycle, and reducing the yield rate of mass production to less than 75%.
[0004] Therefore, there is an urgent need for a device that can conveniently and effectively detect gaps. Utility Model Content

[0017] Optionally, the heat pipe includes an evaporation section, an insulation section, and a condensation section, and the area to be detected includes the evaporation section area corresponding to the evaporation section, the insulation section area corresponding to the insulation section, and the condensation section area corresponding to the condensation section.

[0034] To more clearly illustrate the technical solutions of the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are merely some examples or embodiments of this application. For those skilled in the art, these drawings can be applied to other similar scenarios without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.
[0035] As indicated in this application and claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not specifically singular and may include plural forms. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.
[0036] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0037] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
[0038] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

Moreover, this application should be understood not only through the actual terms used, but also through the meaning implied by each term.
[0040] Figure 1 This is a schematic diagram of a heat pipe 10 according to an embodiment of this application. In this embodiment, the heat pipe 10 includes a casing 101 and a wick located inside the casing 101. Figure 1 (Not shown in the image). A gap exists between the casing 101 and the wick. In this embodiment, each heat pipe 10 has a heat pipe number on its surface, i.e., the surface of the casing 101, which is used to identify the corresponding heat pipe 10. In this embodiment, the heat pipe 10 is a high-temperature heat pipe and is suitable for heat pipe micropiles. It should be noted that this application does not limit the type of heat pipe; in some embodiments, the heat pipe is a low-temperature heat pipe, in some embodiments, the heat pipe is a room-temperature heat pipe, and in some embodiments, the heat pipe is a medium-temperature heat pipe. Further combined with... Figures 2-4 The heat pipe 10 includes an evaporation section pipe body 11, an insulation section pipe body 12, and a condensation section pipe body 13 connected in sequence.
[0041] Continue to refer to Figures 1-4Based on the specific structure of the heat pipe 10 described above, the working process of the heat pipe 10 in this embodiment is explained as follows. First, the heat source supplies heat to the evaporation section tube 11, causing the working fluid liquid inside the evaporation section tube 11 to absorb heat and vaporize to form working fluid vapor. Subsequently, the working fluid vapor flows to the condensation section tube 13 under the action of pressure difference. Next, the condensation section tube 13 releases the latent heat of vaporization to the cold source, thereby causing the working fluid vapor to condense into working fluid liquid. Finally, the condensed working fluid liquid returns from the condensation section tube 13 to the evaporation section tube 11 under the suction force of the wick, thus completing one cycle. The heat pipe 10 continuously operates according to the above cycle, so that the heat from the heat source at one end of the heat pipe 10 (i.e., the side of the evaporation section tube 11) is continuously transferred to the cold source at the other end of the heat pipe 10 (i.e., the side of the condensation section tube 13).
[0042] The structure and operation of the heat pipe in this embodiment have been briefly described above. Next, the heat pipe detection device will be described. Figure 5 This is a structural block diagram of a heat pipe detection device 20 according to an embodiment of this application. Figure 5 As shown, the heat pipe detection device 20 includes a radiographic testing machine 21, a flat panel detector 22, a rotating mechanism 23, a support member 24, a visual inspection mechanism 25, and a host computer 26. The radiographic testing machine 21 includes a radiation source 211, which is adapted to emit radiographic radiation. In this embodiment, the radiographic radiation includes X-rays.
[0043] Continue to refer to Figure 5 The flat panel detector 22 is adapted to support a portion of the heat pipe. This portion includes the area of the heat pipe to be detected, which contains local gaps. In this embodiment, the portion includes an evaporation section, an adiabatic section, and a condensation section. Corresponding to the portion, the area to be detected in this embodiment includes the evaporation section area corresponding to the evaporation section, the adiabatic section area corresponding to the adiabatic section, and the condensation section area corresponding to the condensation section. It should be noted that this application does not limit the range of the heat pipe supported by the flat panel detector; in some embodiments, the flat panel detector is suitable for supporting the entire heat pipe.
[0044] Continue to refer to Figure 5 and Figure 6In this embodiment, when the local tube 14 is located on the flat panel detector 22, the X-ray transmission machine 21 is located on the side of the local tube 14 away from the flat panel detector 22. Preferably, in this embodiment, the X-ray source 211 is located directly above the area to be detected in the local tube 14, so that the center line of the X-ray beam formed by the X-ray transmission emitted by the X-ray source 211 is perpendicular to the center of the area to be detected, and the center line of the X-ray beam coincides with the normal line of the tube shell surface corresponding to the area to be detected. More preferably, in this embodiment, the distance between the X-ray transmission machine 21 and the flat panel detector 22 is not less than 50 times the outer diameter of the heat pipe 10. For example, when the outer diameter of the heat pipe is 20 mm, the distance between the X-ray transmission machine 21 and the flat panel detector 22 is not less than 1000 mm.
[0045] Continue to refer to Figure 5 The flat panel detector 22 is also adapted to acquire radiographic data information corresponding to the radiographic line penetrating the area to be detected. Specifically, in this embodiment, the flat panel detector 22 converts the signal of the radiographic line into a visible light signal through a scintillator, then converts the visible light signal into an electrical signal through an amorphous silicon photodiode, and finally converts the electrical signal into a digital signal file through an analog-to-digital converter, thereby forming radiographic data information. It can be understood that for each radiographic data information corresponding to the area to be detected, the radiographic data information includes gap data information corresponding to the local gap of the area to be detected. In this embodiment, the host computer 26 is communicatively connected to the flat panel detector 22, and the host computer 26 is adapted to acquire the radiographic data information. Further, the host computer 26 is adapted to acquire the size data corresponding to the gap based on the radiographic data information. Specifically, in this embodiment, the host computer 26 converts the radiographic data information into a corresponding X-ray radiographic image. Among them, the host computer 26 converts the gap data information into an image of the local gap in the X-ray radiographic image. Subsequently, the host computer 26 acquires the actual gap measurement value of the corresponding local gap based on the X-ray radiographic image, and uses the actual gap measurement value as part of the size data.
[0046] Continue to refer to Figure 6 In this embodiment, since the distance between the X-ray machine 21 and the flat panel detector 22 is not less than 50 times the outer diameter of the heat pipe 10, the geometric magnification effect on the gap data information can be avoided. Furthermore, the image of the suction core in the X-ray image is proportional to the actual suction core, and the image of the tube shell in the X-ray image is proportional to the actual tube shell. Therefore, the host computer 26 is suitable for directly measuring the distance between the suction core and the tube shell in the X-ray image as the actual gap measurement value. It should be noted that since the area to be detected includes the entire outer diameter of the tube, the same X-ray image contains image information corresponding to the distances on opposite sides, i.e., distance w1 and distance w2. For example, Figure 7 This is an X-ray radiograph of the evaporation section. Figure 8 yes Figure 7A magnified image of a local gap, with the actual measured gap value corresponding to gap d1 being 0.68 mm; Figure 9 It is an X-ray radiograph of the adiabatic section. Figure 10 yes Figure 9 A magnified image of a local gap, with the actual measured gap value corresponding to gap d2 being 0.68 mm; Figure 11 This is an X-ray radiograph of the condensation zone. Figure 12 yes Figure 11 A magnified image of a local gap, with the actual distance measurement corresponding to gap d3 being 0.68 mm.
[0047] It should be noted that in some embodiments, when the distance between the radiography machine and the flat panel detector is less than 50 times the outer diameter of the heat pipe, the distance w between the wick and the shell in the X-ray radiograph cannot be used as the true gap measurement value t due to the geometric magnification effect. Therefore, the host computer needs to perform error correction on the distance w between the wick and the shell in the directly measured X-ray radiograph to obtain the error-corrected true gap measurement value t. The expression for calculating the true gap measurement value t is as follows:
[0048] t = (1 - R / F)w,
[0049] In the formula, R is the outer radius of the heat pipe, which is half of its outer diameter, and F is the distance between the ray-transmitting machine and the flat panel detector.
[0050] Continue to refer to Figure 5 In this embodiment, the radiographic data information includes first radiographic data information and second radiographic data information. The heat pipe is adapted to rotate 90 degrees along its rotation axis after the first radiographic data information is acquired by the flat panel detector 22, so that the flat panel detector 22 acquires the second radiographic data information. The rotation axis is the axial centerline of the heat pipe. Further, for example, refer to... Figure 6 When the first radiographic data information corresponds to an X-ray radiographic image containing spacing w1 and spacing w2, in this embodiment, the heat pipe is rotated along a path perpendicular to the x-ray image using the rotating mechanism 23. Figure 6 The axial centerline in the paper direction is rotated 90 degrees clockwise, so that the second radiographic data information acquired by the flat panel detector 22 includes X-ray radiographic images of spacing w3 and spacing w4. This setup allows for the acquisition of the spacing of gaps at multiple different locations within the same area to be inspected, thus more accurately reflecting the gap condition of the local tube and preventing gap defects at obscured locations from going undetected due to a single radiographic examination.
[0051] Continue to refer to Figure 5Since the clarity of the X-ray radiograph directly affects the accuracy of the actual gap measurement, the radiograph machine 21 and the flat panel detector 22 in this embodiment are configured as follows: In this embodiment, the radiograph machine 21 is a GE ERESCO 65 MF4 constant potential high-frequency X-ray machine. The tube voltage range of the radiograph machine 21 in this embodiment is preferably 170kV to 210kV, thereby ensuring sufficient penetrating power of the radiograph and sufficient clarity of the X-ray radiograph image in the subsequently obtained radiograph data. The exposure range of the radiograph machine 21 in this embodiment is 1mA·s to 2.1mA·s, and the tube current is 3mA, thereby clearly distinguishing the gap in the X-ray radiograph image without overexposure. In this embodiment, the pixel size of the flat panel detector 22 is not less than 76μm, thereby acquiring clear X-ray radiograph images. In this embodiment, the flat panel detector 22 acquires no less than 8 frames for the same area to be detected. For example, for the same area to be detected, the flat panel detector 22 acquires 8 frames of X-ray radiographic images containing spacing w1 and w2 as first radiographic data information, and acquires 8 frames of X-ray radiographic images containing spacing w3 and w4 as second radiographic data information, thereby obtaining the radiographic data information corresponding to the area to be detected. It should be noted that when the number of frames acquired is 8, the improvement in the image normalized signal-to-noise ratio is significantly reduced (≤1.4%), while too many frames acquired will affect the detection efficiency. Therefore, in this embodiment, the number of frames acquired is preferably 8.
[0052] Continue to refer to Figure 5 The support member 24 is suitable for supporting both ends of the heat pipe (i.e., one end near the evaporation section tube body 11 and the other end near the condensation section tube body 13), thereby reducing the force between the heat pipe and the flat plate detector 22, preventing damage to the heat pipe and the flat plate detector 22, and also enabling the heat pipe to maintain its current position when supported by the flat plate detector 22, thus preventing errors in the radiographic data information caused by the movement of the heat pipe.
[0053] Continue to refer to Figure 5The visual inspection mechanism 25 includes a visual sensor 251. The visual inspection mechanism 25 is adapted to acquire a surface image of the heat pipe through the visual sensor 251. The surface image contains surface morphology information, including the heat pipe number. In this embodiment, the host computer 26 is communicatively connected to the visual inspection mechanism 25, and the host computer 26 is adapted to acquire input visual information. In this embodiment, the host computer 26 acquires input visual information containing the surface morphology information of the heat pipe through the visual inspection mechanism 25. It should be noted that this application does not limit the method by which the host computer 26 acquires the input visual information. In some embodiments, the corresponding surface morphology information is obtained by an operator performing a visual inspection of the heat pipe, and the operator inputs the surface morphology information into the host computer 26. In this embodiment, the host computer 26 is also adapted to acquire surface damage data of the heat pipe based on the surface morphology information in the surface image. Furthermore, for heat pipes with surface damage, radiographic data is no longer acquired, and the heat pipe is considered a defective product, thereby improving the inspection efficiency of the heat pipe.
[0054] The heat pipe testing device has been briefly described above. The following section describes the process of using this device to test heat pipes. (Refer to...) Figure 5 and Figure 13 First, the heat pipe is visually inspected by the visual inspection mechanism 25 and the host computer 26 to ensure there is no surface damage and to obtain the corresponding heat pipe number. Then, the heat pipe is sequentially subjected to X-ray radiography by the radiography machine 21, flat panel detector 22, rotating mechanism 23, and support 24, followed by image acquisition and processing to obtain radiographic data. Finally, the host computer 26 obtains the dimensional data corresponding to the gap between the wick and the casing based on the radiographic data, and then performs image evaluation based on the dimensional data.
