Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of test boxes, and more specifically to a double-layer high-temperature test box. Background Art
[0002] The temperature shock test chamber is mainly used to conduct reliability tests on electrical and electronic products, components, parts, and metal materials under high and low temperature conditions, various temperature shocks, and temperature changes. According to national standards or user-defined requirements, the physical and other related characteristics of the product are tested in a simulated extreme environment to determine whether the product's performance can meet the design requirements, so as to discover problems and optimize the product.
[0003] The existing high temperature test chamber is usually single-layer. The single-layer high temperature test chamber needs to occupy a large laboratory area, but can only provide less test chamber space, so that the test personnel need a lot of space, and the data communication between multiple high temperature test chambers is relatively inconvenient. A small number of high temperature test chambers are double-layer structures. The existing double-layer test chamber generally includes a test chamber, and two laboratories arranged in an upper and lower configuration are opened inside the test chamber. The side wall of the test chamber is provided with a control panel, and the two laboratories are controlled by the control panel. The double-layer structure test chamber in the prior art has obvious advantages in space utilization, which can reduce the overall footprint of the equipment, and its two laboratories are uniformly controlled to reduce the possible temperature and humidity fluctuations between different laboratories. Since the existing double-layer test chamber has two laboratories in the chamber, when one laboratory needs to conduct a test at a specific temperature and humidity, the temperature and humidity of the other laboratory will also be affected, resulting in the inability to conduct tests under different conditions at the same time, and it is difficult to achieve independent control. Although the use of unified control can improve the overall stability and reliability of the test chamber and reduce the possible temperature and humidity fluctuations between different laboratories, it also limits the diversity and flexibility of the test, especially when comparative tests under different environmental conditions are required.
