Icing and freezing rain test device and test method

Abstract

The invention relates to an icing and freezing rain test device and test method. The device comprises a test box with adjustable internal temperature, a horizontal rotary table and water spraying equipment, and can spray water mist to a test sample to simulate a real rainwater environment for the test sample. The device is provided with an exhaust pipeline, blast equipment and an air supply pipeline, air in the test box can be used for blowing breeze for a test sample, so that the air pressure and the air temperature in the test box are ensured to be unchanged, and sprayed rainwater can be uniformly attached to the side wall of the test sample by blowing the breeze for the test sample, and the icing of the test sample is more uniform. The device also includes measuring equipment which can measure the thickness of the ice layer on the test sample so as to judge whether the environmental condition required by the experiment is met or not. Therefore, the real environmental stress can be simulated for the test sample before the test sample is actually deployed, and a test environment is provided for checking and verifying the adaptability level of the test sample to an icing and freezing rain environment.

Description

technical field [0001] The present application relates to the technical field of environmental testing, in particular to a freezing rain test device and test method. Background technique [0002] With the development of electronic equipment technology, the requirements for the reliability of electronic equipment are getting higher and higher. Most of the time in my country's Yunnan-Guizhou Plateau and the middle and lower reaches of the Yangtze River are in the harsh environment of freezing rain, and the environment of freezing rain It will cause corresponding physical or chemical effects on the electronic equipment, which will affect the performance of the electronic equipment and even cause damage to the electronic equipment. Therefore, before the actual deployment of the electronic equipment, it is necessary to simulate a real freezing rain environment for the electronic equipment for testing. [0003] In the traditional technology, by placing the electronic equipment in ...
