1. Description:

Three-Zone High and Low Temperature Shock Simulate Test Chamber that subjects a product to alternating extremes of high and low temperatures in order to observe changes in product characteristics and failure occurrence caused by different materials and their thermal expansion coefficients. Thermal shock chamber utilizes controlled areas for hot, ambient and cold temperatures. The product is moved from ambient to hot or ambient to cold zones. The chamber can be programmed to include a dwell period in the ambient zone if desired.It is applicable to metals, plastic, rubber, electronics amongst other materials. The test result can be Used as a reference or basis for product improvement.

Refrigeration operation principle

The level of the refrigeration cycle are used against the card if the cycle, which consists of two isothermal and two adiabatic processes, whose process is as follows: a refrigerant through the compressor adiabatic compression to a higher pressure, the power consumption of the exhaust gas temperature followed by the condenser refrigerant isothermal heat exchange medium in and around the heat to medium four weeks. After the refrigerant flows through the shutoff valve adiabatic expansion work, when the refrigerant temperature decreases. This loop again and again to achieve the purpose of cooling.


Air conditioning system


1) the air control: forced ventilation circulation, balance thermostat method (BTC). This method not only refers to the case of the cooling system for continuous operation, the control system according to the temperature set point of the heater to control the output of the results by automatically calculating PID output, and ultimately achieve a dynamic equilibrium.
2)air circulating means: built between the air circulation fan duct and the long axis of stainless steel, the use of energy efficient refrigerators and regulation system, by effective and efficient heat exchange ventilator, to achieve the purpose of the temperature change. By adjustable air outlet adjusting bolt, thereby significantly improving the chamber temperature uniformity;
3) the air cooling method: multi-stage diaphragm air heat exchanger.
4) air heating: Watkins quality nickel chrome electric heater.


Thermal Shock Chambers maintenance actions
1) a reasonable choice of installation location to install measures: dry, non-drip of rain and snow place.
2) inspection measures qualified by hand daily for insulation materials is broken steam pipe is blocked for technical confirmation and disposal technology.
3) the alarm can be installed as conditional steam leak or power-off state of alarm sound and light small device to facilitate the holding of risk freezing measures discovery and timely remediation.
4) instrument maintenance inspection measures by the area responsible for regular inspection by a predetermined inspection route. To check the insulation inspection of pipeline valve is normal, the incubator is normal, hydrophobic means is normal, thermal insulation material packaging is intact, electric heating power supply and other components is normal.
