Product Specification

IEC60068-2-3 Thermal Shock Environment Test Equipment from -40℃ to +120℃

1. Introduction

The thermal shock test chamber is divided into two-box type and three-box type. The difference is that the test method and internal structure are different. The product conforms to the standard: GB/T2423.1-2008 test A, GB/T2423.2-2008 test B, GB- T10592-2008, GJB150.3-198, GJB360A-96 Method 107 Requirements for temperature impact test. The thermal shock test chamber is an indispensable test equipment for the metal, plastic, rubber, electronics and other materials industries. It is used to test the degree to which a material structure or composite material can withstand in a transient environment of extremely high temperature and extremely low temperature. It is possible to detect chemical changes or physical damage caused by thermal expansion and contraction in the shortest time.

4. Working Pricinple:

A. Low temperature storage room: The temperature state inside the tank is determined by the working state of the heater, evaporator and fan in the air duct. After the refrigerant flowing out through the expansion valve enters the evaporator in the working chamber, the heat in the working chamber is absorbed and vaporized, so that the temperature of the working chamber is lowered; the working fluid after gasification is sucked by the compressor and compressed into high temperature and high pressure gas into the condenser. The medium is condensed into a liquid, and after being screened, finally throttled by the expansion valve, and then re-entered into the evaporator of the working chamber to absorb heat and vaporize and then be sucked and compressed by the compressor. So reciprocating loop work, the studio temperature is lowered to the set temperature requirements.

B. High-temperature storage room: The central controller detects the instantaneous signal from the temperature-sensing component, compares it with the set temperature signal, and obtains the comparison signal. The output of the instrument PID logic circuit controls the turn-on or turn-off time of the solid-state relay to adjust the heater output power. In order to achieve the purpose of automatic temperature control.

C. Impact temperature test chamber: The high and low temperature air valve is automatically controlled by the meter, and is switched between the low temperature or high temperature storage chamber, and a closed circuit air circulation system is formed respectively with the high temperature box or the low temperature box to quickly reach the target temperature of the test.

The temperature state in the test chamber is determined by the operating conditions of the heater, evaporator, and fan in the duct. The working chamber of the test box adopts the forced axial flow “scattering” type loop wind operation, which can greatly improve the parameters such as fluctuation and uniformity of equipment operation.
