Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature testing, in particular to a one-to-many box control structure. Background Art

[0002] Low temperature test chambers are used to test and determine the parameters and performance of electrical, electronic and other products and materials after high temperature, low temperature, or constant temperature environment changes for parts and materials of electronic and electrical, automobile and motorcycle, aerospace, ship weapons, colleges and universities, scientific research institutions and other related products under low temperature cyclic changes. In the prior art, low temperature test chambers use an insulation cavity to carry out low temperature tests.

[0003] That is to say, the existing high temperature test chambers generally have only a single test chamber, and can only perform low temperature tests on a single product at a time, which is inefficient. When multiple products need to be tested at low temperature, they can only be placed in the chamber one by one for testing, which seriously affects the efficiency of the test.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
