[0027] Specific examples are given below.

[0028] See also Figure 1-Figure 7The utility model provides a heat dissipation test device for high heat dissipation composite fabrics, comprising a test box 1; a protective observation door 2 is rotatably connected to one side of the test box 1, and a movable frame 3 is provided on the inner side of the test box 1; the movable frame 3 is slidably connected to the test box 1 through a sliding assembly; a heat conducting plate 5 is fixed at the middle position of the movable frame 3; a heat dissipation fan 20 is fixed on the side of the test box 1 away from the protective observation door 2; a handle 6 is fixed on the side of the movable frame 3 away from the test box 1; a temperature control unit 5 is fixed on the inner side of the test box 1 and below the heat conducting plate 5. Degree measuring instrument 7; a heating lamp 8 is fixed to the inner top of the test box 1; clamping components are provided at the four end corners on the inner side of the mobile frame 3; a cleaning component is also provided on the inner side of the mobile frame 3. The clamping component includes a fixing plate 9; the fixing plate 9 is fixed at the inner end corner of the mobile frame 3; the inner side of the fixing plate 9 is threadedly connected to a driving screw 12; the lower end of the driving screw 12 is rotatably connected to the clamping plate 10; the top of the clamping plate 10 is connected to the fixing plate 9 by two telescopic rods 13; the top of the driving screw 12 is fixed to a knob 11. During operation, when conducting the test, first cut the fabric to a suitable size, and then place the fabric on the inner side of the mobile frame 3; then place the four end corners of the fabric between the clamping plate 10 and the mobile frame 3, and at the same time make the fabric contact with the heat conducting plate 5, and then turn the knob 11; the knob 11 drives the driving screw 12 to rotate, and when the driving screw 12 rotates, because the clamping plate 10 and the driving screw 12 are connected in rotation and are limited by the telescopic rod 13, the clamping plate 10 moves downward, and the end corners of the fabric can be clamped with the mobile frame 3 through the clamping plate 10. Hold and fix, then close the protective observation door 2, turn on the heating lamp 8 to heat the fabric, the fabric conducts heat through the heat conducting plate 5, and then monitors and collects the temperature of the heat conducting plate 5 through the temperature measuring instrument 7 to analyze the heat dissipation effect of the fabric. This step can effectively detect the heat dissipation effect of the fabric through the coordinated structural design of the heating lamp 8, the temperature measuring instrument 7 and the heat conducting plate 5. The four end corners of the fabric can be clamped and fixed by the clamping plate 10, thereby improving the stability of the fabric, avoiding wrinkles on the fabric and causing errors in the test structure, and improving the accuracy of the device;

[0029] Further, such as Figure 2 and Figure 3As shown, the sliding assembly includes two sliders 4, which are fixed at the two ends of the movable frame 3. The sliders 4 are slidably connected to the test chamber 1. A limit assembly is provided inside the test chamber 1 at a position corresponding to the sliders 4. During operation, before testing the fabric, the handle 6 is pulled to allow the heat conducting plate 5 to slide smoothly out of the test chamber 1 via the sliders 4. The limit assembly simultaneously limits the position of the sliders 4. This step effectively improves the stability of the movable frame 3 through the sliders 4 and effectively prevents the movable frame 3 from moving out of the test chamber 1.

[0030] Further, such as Figure 4 As shown, the limit assembly includes a limit block 15; the limit block 15 is arranged on the inner side of the test box 1 and at a side position close to the protective observation door 2; the limit block 15 is slidably connected to the test box 1; the slider 4 is stuck at the position corresponding to the limit block 15 and there is a limit groove 14; the limit block 15 is connected to the slider 4 through the limit groove 14; a first spring 16 is fixed to the end of the limit block 15 away from the limit groove 14; the end of the first spring 16 away from the limit groove 14 is fixedly connected to the test box 1. During operation, when the slider 4 moves in the direction away from the test box 1, the slider 4 squeezes the limit block 15, so that the limit block 15 squeezes the first spring 16 at the same time, causing the first spring 16 to undergo elastic deformation. When the slider 4 moves to the position corresponding to the limit groove 14 and the limit block 15, the limit block 15 is pushed to the inside of the limit groove 14 under the elastic action of the first spring 16, thereby preventing the slider 4 from continuing to move. This step can effectively limit the slider 4 through the matching structural design of the limit block 15 and the limit groove 14, thereby preventing the slider 4 from sliding out from the inside of the test box 1, thereby improving the stability of the slider 4.

[0031] like Figure 4 As shown, the lower end of the clamping plate 10 and the position of the movable frame 3 corresponding to the clamping plate 10 are both provided with anti-slip grooves. During operation, the anti-slip grooves provided at the lower end of the clamping plate 10 and the position of the movable frame 3 corresponding to the clamping plate 10 make the fabric more firmly fixed. This step can effectively improve the stability of the fabric and prevent the fabric from moving.

[0032] like Figure 5As shown, the cleaning assembly includes a brush roller 19; the brush roller 19 is arranged on the inner side of the movable frame 3 and is located above the heat conduction plate 5; a transmission screw 17 is longitudinally arranged on the inner side of both ends of the movable frame 3; the transmission screw 17 is rotatably connected to the movable frame 3; one end of the transmission screw 17 extends to the outside of the movable frame 3; the end of the transmission screw 17 located on the inner side of the movable frame 3 is threadedly connected to the movable seat 18; the movable seat 18 is slidably connected to the movable frame 3; the movable seat 18 is fixedly connected to the brush roller 19; a drive assembly is provided on the inner side of the test box 1 and at a position corresponding to the transmission screw 17. During operation, when the transmission screw 17 rotates, the transmission screw 17 drives the movable seat 18 threadedly connected thereto to slide along the axial direction of the transmission screw 17, thereby driving the brush roller 19 to move at the same time through the movement of the movable seat 18, so that the dust and fluff on the surface of the fabric can be cleaned by the brush roller 19. This step can be effectively achieved through the structural design of the brush roller 19, so that when the transmission screw 17 is driven to rotate by the driving assembly, the transmission screw 17 can drive the movable seat 18 to move, thereby the movable seat 18 drives the brush roller 19 to move, and then the dust and fluff on the surface of the fabric are cleaned by the movement of the brush roller 19, which effectively avoids the occurrence of errors in the test results and improves the accuracy of the device test.

[0033] like Figure 6 As shown, the drive assembly includes a motor 21; the motor 21 is fixed inside the test box 1 at a position corresponding to the transmission screw 17; a connecting shaft 22 is fixed to the output end of the motor 21; and a connecting assembly is provided inside the connecting shaft 22 at a position corresponding to the transmission screw 17. During operation, when cleaning is performed, the transmission screw 17 is plugged into the connecting shaft 22, so that when the motor 21 is started, the connecting shaft 22 is driven to rotate, and when the connecting shaft 22 rotates, the transmission screw 17 is driven to rotate through the connecting assembly. This step can be achieved through the structural design of the connecting assembly, so that when the transmission screw 17 is connected to the connecting shaft 22, the connecting shaft 22 can drive the transmission screw 17 to rotate, and at the same time, the transmission screw 17 can be separated from the connecting shaft 22.

[0034] like Figure 7As shown, the connecting assembly includes a plurality of plug-in blocks 24; the plurality of plug-in blocks 24 are evenly arranged at the inner side of one end of the connecting shaft 22 close to the transmission screw 17; the plug-in blocks 24 are slidingly connected to the connecting shaft 22; a second spring 25 is fixed to the end of the plug-in block 24 away from the transmission screw 17; the end of the second spring 25 away from the plug-in block 24 is fixedly connected to the connecting shaft 22; a plurality of plug-in grooves 23 are evenly opened at the positions corresponding to the transmission screw 17 and the plug-in blocks 24; the plug-in blocks 24 are plug-connected to the transmission screw 17 through the plug-in grooves 23. During operation, when the transmission screw 17 moves in the direction close to the connecting shaft 22, the transmission screw 17 squeezes the plug-in block 24, causing the plug-in block 24 to move in the direction close to the second spring 25. When the transmission screw 17 moves to the position corresponding to the plug-in slot 23 and the plug-in block 24, the plug-in block 24 moves to the inner side of the plug-in slot 23 under the elastic action of the second spring 25, thereby completing the plug-in connection of the transmission screw 17, and then when the connecting shaft 22 rotates, it can drive the transmission screw 17 to rotate. This step can effectively ensure that the transmission screw 17 and the connecting shaft 22 can be easily separated and combined. At the same time, when the transmission screw 17 is connected to the connecting shaft 22, the connecting shaft 22 can drive the transmission screw 17 to rotate, so as not to affect the movement of the movable frame 3.

[0035] Working principle: When conducting the test, first cut the fabric to a suitable size, and then place the fabric on the inner side of the mobile frame 3; then place the four end corners of the fabric between the clamping plate 10 and the mobile frame 3, and at the same time make the fabric contact with the heat conducting plate 5, and then turn the knob 11; the knob 11 drives the driving screw 12 to rotate. When the driving screw 12 rotates, because the clamping plate 10 and the driving screw 12 are connected in rotation and are limited by the telescopic rod 13, the clamping plate 10 moves downward, and the end corners of the fabric can be clamped and fixed to the mobile frame 3 through the clamping plate 10, and then the protective observation door 2 is closed. , turn on the heating lamp 8 to heat the fabric, and the fabric conducts heat through the heat conducting plate 5. Then, the temperature of the heat conducting plate 5 is monitored and collected by the temperature measuring instrument 7 to analyze the heat dissipation effect of the fabric; before the fabric needs to be tested, the handle 6 is pulled to make the heat conducting plate 5 slide smoothly out of the inner side of the test box 1 through the slider 4, and the slider 4 can be limited by the limit assembly; when the slider 4 moves in the direction away from the test box 1, the slider 4 squeezes the limit block 15, so that the limit block 15 squeezes the first spring 16 at the same time, causing the first spring 16 to undergo elastic deformation. When the slider 4 moves to the position where the limit slot 14 corresponds to the limit block 15, When the sliding block 15 is in the position, the elastic action of the first spring 16 pushes the limit block 15 to the inside of the limit groove 14, thereby preventing the slider 4 from continuing to move; the lower end of the clamping plate 10 and the position corresponding to the movable frame 3 and the clamping plate 10 are provided with anti-slip grooves, so that the fabric is fixed more firmly; when the transmission screw 17 rotates, the transmission screw 17 drives the movable seat 18 threadedly connected thereto to slide along the axial direction of the transmission screw 17, thereby driving the brush roller 19 to move at the same time through the movement of the movable seat 18, so that the dust and fluff on the surface of the fabric can be cleaned by the brush roller 19; when the cleaning operation is performed, the transmission screw 17 is used to move the movable seat 18 to move the movable seat 18 to move the brush roller 19 to move the fabric ... It is plugged into the connecting shaft 22, so that when the motor 21 is started, the connecting shaft 22 is driven to rotate, and when the connecting shaft 22 rotates, the transmission screw 17 is driven to rotate through the connecting assembly; when the transmission screw 17 moves in the direction close to the connecting shaft 22, the transmission screw 17 squeezes the plug-in block 24, so that the plug-in block 24 moves in the direction close to the second spring 25, and when the transmission screw 17 moves to the position corresponding to the plug-in slot 23 and the plug-in block 24, the plug-in block 24 moves to the inner side of the plug-in slot 23 under the elastic action of the second spring 25, thereby completing the plug-in connection of the transmission screw 17, and then when the connecting shaft 22 rotates, it can drive the transmission screw 17 to rotate.
