The high and low temperature laboratory can be used to assess and determine the adaptability of electrical and electronic products or materials to storage and use under high or low temperature environmental conditions when the temperature cycle changes. Widely used in aerospace products, information electronic instruments, materials, electrical, electronic products and other industries.

High and low temperature laboratory design standards:

"High and low temperature impact test chamber GB10592-89 standard" "Constant temperature and humidity test chamber GB10586-89 standard"

GB/T2423.1-2008 Environmental Test for Electrical and Electronic products GB/T2423.1-2001 High Temperature Test Method

GB/T 2423.3-93 Alternating humid Heat test Method

Description of the overall structure of the high and low temperature laboratory:

Material used: outer box material high quality carbon steel plate. Phosphating electrostatic spray treatment; Inner box material SUS304 stainless steel high quality light plate;

Insulation material: polyurethane rigid foam;

The door seal is made of double-layer silicone rubber sealing material;

Observation window: multi-layer conductive film tempered insulating glass, in order to prevent the glass frosting at low temperature, special built-in special heating wire surround; It is also equipped with a light to provide illumination for observation.

Box structure: there is a 50mm test hole with a stopper on the side of the box. The stopper material is low foaming silicone rubber, which can withstand high and low temperature and has thermal insulation effect.

Large walk-in test box control system adopts: imported programmable touch LCD Chinese dialogue display, microcomputer integrated controller.

Chamber base: 8# channel steel welded into a mesh frame, in order to be able to withstand the weight of the chamber body and personnel specimens under horizontal conditions, without the bottom surface of the chamber uneven and cracking, bearing 200kg/ per square meter.

Chamber body: (the main body of the laboratory (shell)) is divided into six chambers and a double-open chamber body door, the size is 1800× 2000 mm, the chamber body material is the inner liner high-quality stainless steel plate (to prevent the inner wall from rusting in the humidity state for a long time), the outer liner is the high-quality color steel plate, the insulation medium is polyurethane hard foam heat insulation, light weight resistance, good heat insulation performance, The door material is also made of color steel plate, and the door handle is open inside and outside, so that the test personnel can freely open the door from the closed room.

Protection system: overall equipment overtemperature, overall equipment underphase/reverse phase;

Refrigeration system overload, refrigeration system overpressure, overall equipment timing;

Others have leakage, water shortage, operation indication, automatic shutdown after fault alarm protection;
