Constant temperature test box for electronic products

Abstract

This application discloses a constant temperature test box for electronic products. The constant temperature test box includes an inner box unit and an outer box unit of the outer casing, wherein the inner box unit and the outer box unit are communicated with mutually independent air inlet passages and outlets. Then, the electronic equipment is placed inside the inner box unit, and the fan outlet of the electronic equipment is communicated with the air outlet channel; in addition, there is also a return flow channel connected between the air outlet channel and the inner box unit; thus, the electronic equipment On the one hand, the heat generated during the test can be discharged from the outer box unit through the air outlet channel, and on the other hand, the heat can flow back to the inner box unit through the return channel to heat the electronic equipment; The temperature drift caused by the test box and the technical problem that affects the test accuracy achieve the technical effect of improving the constant temperature test accuracy of electronic equipment, and can save energy.

Description

technical field [0001] The invention relates to the technical field of testing devices, in particular to a constant temperature test box for electronic products. Background technique [0002] For electronic equipment, due to the difference in the specific use environment, especially the temperature in the environment, it is usually necessary to perform performance tests on the electronic equipment in a constant temperature environment at different temperatures before use, so as to ensure that the electronic equipment can operate under different temperature environments. normal work. [0003] The above-mentioned performance tests at different temperatures usually need to be carried out in a constant temperature test box. Most of the existing constant temperature test boxes have a box structure integrating a cooling module and a heating module, and then the cooling module or the heating module are separated in the box. Create environments with different target temperatures to...

AI Technical Summary

Problems solved by technology

[0004] However, it was found that the actual temperature of the constant temperature test box will produce temperature drift compared with the set target temperature, which will bring errors to the constant temperature test of electronic equipment and seriously affect the accuracy of the constant temperature test
