Description

Technical Field

[0001] This utility model relates to the technical field of impact test chambers, specifically a self-cleaning, anti-icing thermal shock test chamber. Background Technology

[0002] A thermal shock test chamber is a device used to test the performance stability of materials or products under extreme temperature changes. It is widely used in electronics, automotive, aerospace and other fields. By rapidly switching between high temperature and low temperature environments (usually switching between two or more independent temperature ranges), it simulates sudden cooling and heating conditions to evaluate the thermal shock resistance of samples. However, when conducting low temperature tests, ice layers are prone to form on the inner wall of the test chamber. Existing methods rely on manual or hot air blowing to melt the ice, resulting in low de-icing efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a self-cleaning, anti-icing thermal shock test chamber.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses a self-cleaning, anti-icing thermal shock test chamber, comprising a test chamber having a hot test chamber and a cold test chamber. The inner wall of the cold test chamber is provided with hot air heating plates on its periphery, and the inner cavity of each hot air heating plate has multiple parallel first air ducts. Both sides of the hot air heating plate are provided with first air pipes connected to the two ends of the first air ducts. A heating cylinder is provided on the test chamber, and an air heating wire is provided inside the heating cylinder. One end of the heating cylinder is connected to one end of the first air pipe via a heat-insulated air guide pipe; the other end of the first air pipe extends out of the cold test chamber via the heat-insulated air guide pipe.

[0005] As a preferred technical solution of this utility model, the cold test chamber is also provided with a heating base at the bottom of the water receiving tank. The heating base is provided with a second air duct arranged in parallel inside, and the heating base is provided with a second air pipe communicating with the second air duct on both sides. One end of the heating cylinder is connected to one end of the second air pipe through a heat-insulating air guide pipe; the other side of the second air pipe extends out of the cold test chamber through the heat-insulating air guide pipe.

[0006] As a preferred embodiment of the present invention, the bottom periphery of the cold test chamber is provided with a downwardly recessed water receiving groove, and the inner wall of the cold test chamber is provided with an inwardly recessed groove for the water receiving groove to be embedded, so that the opening of the water receiving groove is located directly below the side wall of the cold test chamber.

[0007] As a preferred embodiment of this utility model, a handle is provided on the outer wall of the water receiving tank.

[0008] As a preferred embodiment of this utility model, the hot air heating plate is an aluminum plate.

[0009] As a preferred technical solution of this utility model, it also includes an air preheating block placed on the compressor inside the test chamber, and the air preheating block is provided with a preheating air duct, and the air inlet end of the heating cylinder is connected to one end of the preheating air duct.

[0010] The beneficial effects of this utility model are: 1. This self-cleaning, anti-icing thermal shock test chamber features hot air heating plates on the periphery of the inner wall of the cold test chamber. Multiple parallel first air ducts are arranged within the inner cavity of these heating plates and connected by first air pipes. A fan delivers high-temperature gas heated by an air heating wire into the first air ducts to heat the hot air heating plates. The ice on the surface of the heating plates melts at the contact points, and the ice detaches under its own force, thus completing the de-icing process. The detached ice and melted water are collected in a water collection tank. This design moves the heating components externally, preventing damage caused by excessively low temperatures within the cold test chamber.

[0011] 2. The cold test chamber of this self-cleaning anti-icing thermal shock test chamber is also equipped with a heating base at the bottom of the water receiving tank. The heating principle of the heating base is the same as that of the hot air heating plate, which is heated by hot air. This prevents the water receiving tank and the cold test chamber from freezing and sticking together, making them difficult to disassemble. Attached Figure Description

[0014] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0015] Example: Figure 1-5 As shown, this utility model discloses a self-cleaning anti-icing thermal shock test chamber, comprising a test chamber 1 having a thermal test chamber 2 and a cold test chamber 3. Hot air heating plates 4 are provided on the periphery of the inner wall of the cold test chamber 3, and multiple parallel first air ducts 5 are provided within the inner cavity of the hot air heating plates 4. First air pipes 11, connected to the two ends of the first air ducts 5, are provided on both sides of the hot air heating plates 4. A heating cylinder 6 is provided on the test chamber 1, and an air heating wire 7 is provided inside the heating cylinder 6. One end of the heating cylinder 6 is connected to one end of the first air pipe 11 via a heat-insulated air guide pipe 8; the other end of the first air pipe 11 extends out of the cold test chamber 3 via the heat-insulated air guide pipe 8. By providing hot air heating plates 4 on the periphery of the inner wall of the cold test chamber 3, and providing multiple parallel first air ducts 5 in the inner cavity of the hot air heating plates 4, and connecting the first air ducts 5 through the first air pipes 11, and by using a fan to transport high-temperature gas heated by the air heating wire 7 into the first air ducts 5 to add hot air heating plates 4, the contact points of the ice layer on the surface of the hot air heating plates 4 will melt, and the ice will fall off under its own action, thus completing the de-icing work. The fallen ice layer and the melted water are collected by the water receiving tank. In this way, the heating components are moved outward to avoid damage caused by excessively low temperature in the cold test chamber 3.

[0016] The cold test chamber 3 also has a heating base 10 at the bottom of the water receiving tank 9. The heating base 10 has parallel second air ducts 12 inside, and second air pipes 13 communicating with the second air ducts 12 are provided on both sides of the heating base 10. One end of the heating cylinder 6 is connected to one end of the second air pipe 13 via a heat-insulating air guide pipe 8; the other side of the second air pipe 13 extends out of the cold test chamber 3 via the heat-insulating air guide pipe 8. The heating base 10 at the bottom of the water receiving tank operates on the same principle as the hot air heating plate 4, using hot air heating to prevent the water receiving tank and the cold test chamber 3 from freezing and sticking together, making disassembly difficult.

[0017] The cold test chamber 3 has a downwardly recessed water receiving groove 9 on its bottom periphery, and an inwardly recessed groove on its inner wall for the water receiving groove 9 to be embedded in, so that the opening of the water receiving groove 9 is located directly below the side wall of the cold test chamber 3, which has a better water and ice receiving effect.

[0018] The water receiving tank 9 has a handle 14 on its outer wall, which makes it easy to assemble and disassemble the water receiving tank.

[0019] The hot air heating plate 4 is made of aluminum, which provides better heat exchange and conduction.

[0020] It also includes an air preheating block 15 placed on the compressor inside the test chamber 1, and the air preheating block 15 is provided with a preheating air duct 16. The air inlet end of the heating cylinder 6 is connected to one end of the preheating air duct 16, so as to preheat the air and reduce energy consumption.

[0021] During operation, this self-cleaning, anti-icing thermal shock test chamber features hot air heating plates 4 on the periphery of the inner wall of the cold test chamber 3. Multiple parallel first air ducts 5 are arranged within the inner cavity of the hot air heating plates 4, connected by first air pipes 11. A fan delivers high-temperature gas heated by air heating wires 7 into the first air ducts 5 to heat the hot air heating plates 4. The ice on the surface of the hot air heating plates 4 melts at the contact points, and the ice detaches under its own force, thus completing the de-icing process. The detached ice and melted water are collected by a water collection tank. This relocation of the heating components prevents damage caused by excessively low temperatures within the cold test chamber 3.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
