Abstract

The invention discloses a multifunctional environmental test box, which comprises a first heating box internally provided with an electric heating element used for heating air, a second heating box and a test box. The second heating box is connected with the first heating box through a blocking device capable of achieving air communication or closing functions, an electric heating element and a fan are arranged in the second heating box to heat the air and generate hot air. The test box is communicated with the second heating box through an air channel capable of achieving opening and closing functions, and a fan and a liquid nitrogen distributor are arranged in the test box. The environmental test box is capable of achieving quick heating and quick cooling through the liquid nitrogen cooling mode due to the fact that a heating system of the environmental test box adopts the two heating boxes and a plurality of electric heating elements. The environmental test box is capable of achieving functions of different environment tests such as temperature impact tests, high low temperature quick temperature change tests and high low temperature circulation tests, correspondingly improves convenience for operators and reduces equipment purchase cost.

Description

technical field [0001] The present invention relates to the field of environmental testing, more specifically, to an environmental testing chamber and its corresponding environmental testing method and application. Background technique [0002] At present, the environmental test chambers mainly include temperature shock test chambers, high and low temperature rapid temperature change chambers, high and low temperature cycle chambers, high temperature chambers and low temperature chambers, etc. Their structures are very similar, including: heating system, refrigeration system, temperature control System and box mechanical structure, etc. Among them, the temperature shock test chamber is used to test the degree to which the material structure or composite material can withstand the continuous environment of extremely high temperature and extremely low temperature in an instant, so as to test the chemical reaction caused by thermal expansion and contraction in the shortest time...
