[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] Please see Figures 1-5This utility model provides a temperature-adjustable cooling film performance testing chamber, including a base 1 and a rotating placement frame 2. A temperature-adjustable transparent testing chamber 3 is fixedly connected to the top of the base 1. The rotating placement frame 2 is placed inside the temperature-adjustable transparent testing chamber 3. Limiting sliding rods 4 are slidably connected to both sides of the rotating placement frame 2. One end of the limiting sliding rod 4 extends through the inner side of the rotating placement frame 2. A limiting pressure plate 5 is fixedly connected to the end of the limiting sliding rod 4 located inside the rotating placement frame 2. A pull block 6 is fixedly connected to the end of the limiting sliding rod 4 away from the rotating placement frame 2. A compression spring 7 is sleeved on the end of the limiting sliding rod 4 located outside the rotating placement frame 2. The two ends of the compression spring 7 are fixedly connected to the surfaces of the rotating placement frame 2 and the pull block 6, respectively. A support post 8 is fixedly connected to the middle of the bottom of the inner wall of the temperature-adjustable transparent testing chamber 3. The bottom of the rotating placement frame 2 is rotatably connected to the top of the support post 8. During operation, the base 1 supports the temperature-adjustable transparent testing chamber 3. Since the testing conditions require light... Under the specified conditions, the temperature change transparent testing chamber 3 is made of transparent glass. The rotating placement frame 2 is set inside the temperature change transparent testing chamber 3. Before testing, pull the pull block 6, which in turn moves the limiting sliding light rod 4, separating the two limiting pressure plates 5. Then, the cooling film is inserted into the rotating placement frame 2. After releasing the pull block 6, due to the elastic force of the compression spring 7, the pull block 6 will be pulled, causing the limiting sliding light rod 4 to move again, moving the two limiting pressure plates 5 towards each other to clamp and position the cooling film. In addition, a support pin 8 is set to rotate and support the rotating placement frame 2. The entire system, by setting the rotating placement frame 2 and cooperating with the limiting pressure plates 5 to clamp and position the cooling film, forms a sealed area. The rotating placement frame 2 can also rotate. This rotation of the sealed area can create airflow, accelerating the air circulation inside the temperature change transparent testing chamber 3, allowing the temperature to spread quickly and evenly. The rotation of the cooling film allows for multi-position testing, further improving the accuracy of the test results.

[0019] Furthermore, such as Figure 1 , Figure 2 and Figure 4As shown, a sealing cover 9 is snapped onto the top of the temperature change transparent detection chamber 3. A motor cylinder 10 is fixedly connected to the middle of the top of the sealing cover 9, and a motor 11 is fixedly connected inside the motor cylinder 10. The output shaft of the motor 11 is fixedly connected to a transmission shaft 12 via a coupling. One end of the transmission shaft 12 passes through the sealing cover 9 and extends to the bottom of the sealing cover 9. The end of the transmission shaft 12 at the bottom of the sealing cover 9 is fixedly connected to the top of the rotating placement frame 2. During operation, the sealing cover 9 seals the temperature change transparent detection chamber 3 to prevent heat loss. At the same time, the sealing cover 9 supports the motor cylinder 10, which houses and fixes the motor 11. After the motor 11 starts working, it drives the transmission shaft 12 to rotate through the output shaft. The rotation of the transmission shaft 12 drives the rotating placement frame 2 to rotate, thereby accelerating the air circulation inside the temperature change transparent detection chamber 3, enabling rapid and uniform temperature diffusion, and providing energy for multi-position detection of the cooling film.

[0020] Furthermore, such as Figure 2 and Figure 3 As shown, both sides of the inner wall of the temperature change transparent detection chamber 3 are fixedly connected to a mounting bracket 13. An electric heater 14 and a cooler 15 are respectively fixedly connected to both sides of the inner wall of the temperature change transparent detection chamber 3 via the mounting bracket 13. During operation, the mounting bracket 13 is fixedly placed on both sides of the inner wall of the temperature change transparent detection chamber 3, and the electric heater 14 and cooler 15 are fixedly installed by the mounting bracket 13 to regulate the internal temperature of the temperature change transparent detection chamber 3.

[0021] Furthermore, such as Figure 1 , Figure 3 and Figure 5 As shown, a mounting bracket 16 is fixedly connected to the surface of the temperature change transparent detection box 3, and a water storage tank 17 is snapped into the inside of the mounting bracket 16; circulating heat exchange pipes 18 are connected to both sides of the water storage tank 17, one end of the circulating heat exchange pipe 18 extends into the inside of the temperature change transparent detection box 3, and a pipe support frame 19 is fixedly connected to the inner wall of the temperature change transparent detection box 3, and the circulating heat exchange pipe 18 is snapped into the inside of the pipe support frame 19. During operation, the temperature change transparent detection box 3 is fixedly supported by the mounting bracket 16, which in turn fixes the water storage tank 17. The two ends of the water storage tank 17 are connected to the circulating heat exchange pipes 18, allowing the water inside the water storage tank 17 to flow into the circulating heat exchange pipes 18. At the same time, the pipe support frame 19 is fixed to the inner wall of the temperature change transparent detection box 3, supporting the circulating heat exchange pipes 18. The circulating heat exchange pipes 18 exchange heat inside the temperature change transparent detection box 3. By setting up the water storage tank 17 and the circulating heat exchange pipes 18, heat can be stored inside the temperature change transparent detection box 3 when the detection is completed or when the temperature changes from high to low temperature, thus improving the adaptability of the detection.

[0022] Working Principle: During testing, the temperature varies slightly at different locations inside the chamber, leading to issues with the accuracy of performance testing. First, the base 1 supports the temperature-change transparent testing chamber 3. Since the test requires illumination, the temperature-change transparent testing chamber 3 is made of transparent glass. The rotating placement frame 2 is positioned inside the temperature-change transparent testing chamber 3. Before testing, pulling the lever 6 moves the limiting sliding light rod 4, separating the two limiting pressure plates 5. Then, the cooling film is inserted into the rotating placement frame 2. Releasing the lever 6 causes the compression spring 7 to pull the lever 6, moving the limiting sliding light rod 4 again, causing the two limiting pressure plates 5 to move towards each other. The cooling film is clamped and positioned, and a support post 8 is provided to support the rotation of the rotating placement frame 2. The rotating placement frame 2, together with the limiting pressure plate 5, clamps and positions the cooling film, creating a sealed area. The rotating placement frame 2 can rotate, allowing airflow within the sealed area and accelerating air circulation inside the temperature change transparent detection chamber 3, resulting in rapid and uniform temperature diffusion. The rotation of the cooling film enables multi-position detection, further improving the accuracy of the test results. Furthermore, the sealing cover 9 seals the temperature change transparent detection chamber 3 to prevent heat loss and supports the motor cylinder 10, which houses the motor 11. When the motor 11 is running, it drives the transmission shaft 12 via the output shaft. The rotation of the transmission shaft 12 drives the rotating placement frame 2, providing power for accelerating air circulation inside the temperature change transparent detection chamber 3, ensuring rapid and uniform temperature diffusion, and enabling multi-position detection of the cooling film. Meanwhile, brackets 13 are fixedly placed on both sides of the inner wall of the temperature-change transparent detection chamber 3, and electric heaters 14 and coolers 15 are fixedly installed on the brackets 13 to regulate the internal temperature of the temperature-change transparent detection chamber 3. Finally, brackets 16 are fixedly mounted on the temperature-change transparent detection chamber 3, and water storage tank 17 is fixedly mounted on the brackets 16. The two ends of the water storage tank 17 are connected to circulating heat exchange pipes 18, so that the water inside the water storage tank 17 can flow into the circulating heat exchange pipes 18. At the same time, pipe support frame 19 is fixed to the inner wall of the temperature-change transparent detection chamber 3, and the circulating heat exchange pipes 18 are supported by the pipe support frame 19. The circulating heat exchange pipes 18 exchange heat inside the temperature-change transparent detection chamber 3. By setting up the water storage tank 17 and the circulating heat exchange pipes 18, heat can be stored inside the temperature-change transparent detection chamber 3 when the detection is completed or when the temperature changes from high temperature to low temperature, thereby improving the adaptability of the detection.
