Description

technical field [0001] The invention belongs to the technical field of temperature test equipment, and in particular relates to a two-box type high and low temperature impact test box. Background technique [0002] As an important testing equipment, the temperature shock test chamber is mainly used to test the safety performance of electronic components and provide reliability test, product screening test, etc. The temperature shock test chamber test can effectively improve the reliability of the product and can Effective quality control of products; with the continuous improvement of product quality requirements, temperature shock test chambers are widely used in aviation, automobiles, home appliances and other technical fields. [0003] Existing temperature shock test chambers include two-chamber temperature shock test chambers and three-chamber temperature shock test chambers; wherein, for two-chamber temperature shock test chambers, it includes a low-temperature chamber ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a two-box type high and low temperature impact test box to solve the problem of the low temperature test box and the high temperature test box when the hanging basket passes through the interval platform between the low temperature test box and the high temperature test box during the lifting process. The temperature will be connected through the ventilation groove of the hanging basket, so that the high temperature and low temperature will be connected together, which will greatly increase the temperature in the low temperature test chamber and reduce the temperature in the high temperature test chamber, so that the low temperature test chamber can maintain the cooling and cooling of the set temperature. The high temperature test chamber needs to consume more energy to maintain the temperature rise of the set temperature, and the problem of high operating cost
