The composition and structure of three box cold and thermal shock test chamber are as follows:

The equipment of three box cold and hot impact test chamber is divided into three parts: low temperature laboratory (energy storage plate, heater and evaporator), high temperature laboratory (energy storage plate and heater) and impact temperature test room (temperature and humidity sensor and sample placement rack). The test products are placed in the test area. During impact, the temperature of high temperature area or low temperature area rushes into the test area for impact, The test product is static. It also includes control system, refrigeration system, heating system (heating wire), air duct system (fan blade, motor), drainage system and protection system (overload, overvoltage, leakage, etc.)

The temperature range is - 60 to + 150 ℃, the impact recovery time is within 8s, and the stability is within 5min. Three boxes of temperature impact test box are necessary products in your laboratory.

note appended:

Purpose of three box cold and hot shock test chamber: it is mainly used to test electrical parts, automation parts, semi-finished products, metals, chemical materials, communication components, PCB base plate electronic chips and other materials. The test sample can withstand different environments under the continuous temperature change environment of high and low temperature, Test the chemical changes and physical damage caused by thermal expansion and cold contraction under the condition of rapidly changing temperature difference. You can have a clearer understanding of its performance.
