Description

Technical Field

[0001] The utility model relates to the technical field of environmental test chambers, and more specifically to an integrated high-temperature chamber. Background Art

[0002] With the rapid development of science and technology, electronic products have become an indispensable part of modern society. In order to ensure that electronic products can maintain their performance and quality under various environmental conditions, the environmental testing industry has emerged. Among them, the aging test chamber, as one of the core equipment in the industry, plays a vital role. Aging tests usually include: ozone aging, ultraviolet aging, xenon lamp aging, ventilation heat aging, high temperature aging, salt spray corrosion aging and many other aging test methods. High temperature aging test is a test method for high-performance electronic products (such as computer complete machines, power supplies, motherboards, monitors, etc.) to simulate a high temperature and harsh environment. It is an important experimental basis for improving product stability and reliability. Through high temperature aging test, defective parts can be checked and the quality of products can be fully improved.

[0003] At present, the common high-temperature aging test method is to place the sample in an incubator and heat the incubator through a heating element, thereby baking the sample at high temperature. However, this test method has some problems.

This uneven heat distribution may cause thermal stress on the device on the sample, thereby affecting the stability and reliability of the sample.

[0004] Secondly, static high-temperature baked samples cannot simulate the dynamic thermal environment during actual use. In actual applications, electronic products may be affected by heat flow in different directions, resulting in high-temperature aging test results that cannot fully reflect the performance of the samples in actual use.

Specifically, the integrated high temperature box provided by the embodiment of the utility model adopts the design of lower layer air inlet and top air outlet, which is helpful to form natural convection of air, so that the hot air rises and is discharged from the top, while the fresh air enters from the bottom, realizing the dynamic circulation of air in the box body 1, ensuring that the hot air can fully contact with the surface of the sample, so that the surface of the sample can be evenly heated, thereby improving the test accuracy of the high temperature aging test. Secondly, an air duct 13 is arranged inside the box 1, and the air duct 13 is independently arranged outside the accommodating cavity, and a heater 2 is arranged inside the air duct 13, so that the air entering the box 1 from the outside is heated in the air duct 13 and then transported to the accommodating cavity, and the hot air in the air duct 13 is continuously transported to the accommodating cavity, and at the same time, part of the air in the accommodating cavity is discharged through the air outlet 12 on the top wall of the box 1. Compared with the traditional solution of directly setting the heating source in the accommodating cavity of the box 1, the utility model adopts this structural design, which can avoid local overheating in the accommodating cavity, ensure the uniform temperature in the accommodating cavity, and thus ensure that the surface of the sample is heated uniformly. Moreover, the utility model adopts this structural design, which can form dynamic hot air in the accommodating cavity, so that the hot air can fully contact with the surface of the sample, thereby improving the test accuracy of the high temperature aging test.
