Description

Technical Field

[0001] The utility model relates to the technical field of dual-temperature test boxes, in particular to a dual-temperature box system test box. Background Art

[0002] A dual-temperature test chamber is a device used to simulate and test the performance changes of materials and products under different temperature environments. It enables the test sample to switch between two different temperature environments and is usually used for hot and cold cycle tests, temperature shock tests, etc., to help evaluate the durability, reliability and stability of the material. The interior of a dual-temperature test chamber is usually divided into two independent temperature zones, each of which can be set to a different temperature. For example, one zone is set to high temperature and the other to low temperature. This design allows temperature shock tests to be performed in one test chamber, and samples can be quickly transferred from one temperature environment to another. Compared with a test chamber with independent dual temperature zones, a single-chamber dual-temperature test chamber can achieve two different temperature environments in the same chamber. It can quickly switch temperatures within a single chamber, thereby simulating temperature shock or temperature cycle tests without moving samples or using two independent test chambers.

[0003] However, when a single chamber of an existing dual-temperature chamber system test chamber switches temperature, the temperature control device is generally set in one direction of the chamber, which causes the gas environment inside the chamber to heat up or cool down unevenly. This not only affects the heating efficiency, but also easily causes the local temperature in the chamber to exceed or fall below the set temperature, thereby resulting in insufficient temperature control accuracy.
