Thermal Shock Chamber.pdf

1. Description:

Thermal Shock Chamber is the perfect testing machine of electronic components, metal, chemical materials, automation components, communication module, national defense industry, aerospace industry, BGA, PCB substrate, electronic chip IC, semiconductor ceramic and high polymer materials.Degree in an instant by the extremely high temperatures and extremely low temperature environment can tolerate continuous, whereby chemical changes in the most short time to test its thermal expansion and contraction caused by physical damage

2. Specifications

Product Advantage

2. CLIMATE provides you with a new type of thermal shock test chamber

4. The uniform temperature stress can be applied to the sample.

5. Widely used in research, development and testing, production and other fields.

Product Features

1. The temperature recovery time of sample was shortened by two cases.

2. Two box method was adopted to shorten the testing time.

3. Greatly reduces the vibration impact of the sample when it's moving in experimentation area.

Control

Operation and settings simplified by the use of a touch-screen LCD display (instructions displayed on-screen). At-aglance confirmation of test patterns, test area temperatures, temperature cycles, and trend graph displays.

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.
