The high and low temperature test chamber has the function of simulating the law of atmospheric environmental temperature changes. Mainly aimed at the adaptability test of electrical, electronic products and their components and other materials in the process of transportation and use under high and low temperature
comprehensive environments. Used for product design, improvement, identification and inspection. I will encounter the phenomenon of ice blocking in the high and low temperature test chamber during use. How to prevent this phenomenon?
In the pressurization test leak, completely remove the moisture in the intake part of the high and low temperature test box. Rejecting moisture is the key to preventing ice blockage. An effective method is introduced below for reference. Make a high-efficiency filter drier: Find an iron can with a sealed lid, drill 6mm round holes at the bottom of the box, and weld about 200 grams of dry calcium chloride (you can also see the effective volume of the iron can) at the round holes (optional Large piece) Put it in a thick nylon stocking or nylon bag. When putting it in an iron can, remove the plug and connect the exhaust port and the air inlet pipe of the compressor with a hose. After use, the two pipes must be closed. mouth.
