DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] A device for detecting the thermal insulation performance of an aluminum-zinc-plated thermal insulation integrated board comprises a detection box 1, a box door 2 is arranged at the front opening of the detection box 1, a handle 3 is arranged on the box door 2, a shell 4 is arranged at the bottom of the detection box 1, the shell 4 is arranged at the top opening, a magnet frame 5 is arranged inside the top opening of the shell 4, an electric heating plate 6 is arranged at the top of the detection box 1, the top of the detection box 1 is connected to a low-temperature nitrogen inlet pipe 7, a nitrogen pump 8 and a nitrogen solenoid valve 9 are arranged on the low-temperature nitrogen inlet pipe 7, a plurality of first temperature sensors 10 are arranged from top to bottom in the detection box 1, and second temperature sensors 11 are respectively arranged on the inner side and bottom of the shell 4. When the utility model is used, the aluminum-zinc-plated thermal insulation integrated board sample to be tested is placed on the top of the shell 4 and can completely cover the top opening of the shell 4, and the aluminum-zinc-plated thermal insulation integrated board sample to be tested is fixed at the top opening of the shell 4 through the magnet frame 5. Since the substrate of the aluminum-zinc-plated thermal insulation integrated board sample to be tested is an aluminum-zinc-plated steel plate, it can be magnetically matched with the magnet frame 5, and the material of the shell 4 is a polymer thermal insulation material and cannot conduct heat, thereby ensuring the accuracy of the test result. After the aluminum-zinc-plated thermal insulation integrated board sample to be tested is fixed, the box door 2 is closed, and then the nitrogen pump 8 and the nitrogen solenoid valve 9 are turned on to pass low-temperature nitrogen into the detection box 1 through the first temperature sensor 10, so that the temperature in the monitoring box 1 can be monitored in real time and when the specified temperature is reached, the temperature sensor 10 can be used to monitor the temperature in the monitoring box 1. The temperature in the test box 1 is maintained for a specified time by controlling the opening degree of the nitrogen solenoid valve 9, and then the temperature change in the shell 4 is monitored in real time by the second temperature sensor 11, so as to accurately know the thermal insulation performance of the aluminum-zinc-coated thermal insulation integrated panel sample to be tested at a specified low temperature; then the nitrogen pump 8 and the nitrogen solenoid valve 9 are closed, and the electric heating plate 6 is turned on to continuously heat the temperature to the specified temperature and maintain it at the specified temperature for a specified time, and then the temperature change in the shell 4 is monitored in real time by the second temperature sensor 11, so as to accurately know the thermal insulation performance of the aluminum-zinc-coated thermal insulation integrated panel sample to be tested at a specified high temperature, thereby conveniently completing the thermal insulation performance test of the aluminum-zinc-coated thermal insulation integrated panel in a higher temperature environment and a lower temperature environment.

[0015] Specifically, since the surface of the aluminum-zinc-coated thermal insulation integrated board sample to be tested may have unevenness on the outer edge of the board surface due to the shearing process, the gap between the aluminum-zinc-coated thermal insulation integrated board sample to be tested and the shell 4 may cause gas exchange inside and outside the shell 4 during the test process, affecting the test results. In order to overcome the above problem, the outer periphery of the top of the shell 4 described in this embodiment is provided with an insulating rubber frame 12, and the cross-sectional area of ​​the insulating rubber frame 12 decreases from top to bottom. In the utility model, the gap between the aluminum-zinc-coated thermal insulation integrated board sample to be tested and the shell 4 can be blocked by the insulating rubber frame 12, thereby ensuring the accuracy of the test results.

[0016] Specifically, a sealing gasket 13 is provided inside the box door 2 of the present embodiment. The utility model can increase the sealing performance of the box door 2 through the sealing gasket 13, thereby ensuring the accuracy of the detection result.

[0017] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
