What is thermal shock?
Thermal shock means that the object generates a large amount of heat exchange in a short time due to rapid heating or cooling. When the temperature changes drastically, the object produces thermal shock. This phenomenon is called thermal shock.
When a metallic material is subjected to rapid heating and cooling, a large temperature difference occurs inside it, which has a large effect on thermal stress. This phenomenon is called thermal shock.
A large thermal shock generates thermal stresses that can exceed the yield strength of the material and cause damage to the metal parts.
What is a thermal shock chamber?
A thermal shock chamber is a type of structural or composite material that can be tolerated in a continuous environment of extremely high temperatures and extremely low temperatures in an instant, causing thermal expansion and contraction in a very short time. Chemical changes and physical damage to the machine.
There are two main ways for the thermal shock:
The thermal shock chamber has two chambers (high temperature zone and low temperature zone), the high temperature zone and low temperature zone are filled with silicone oil, and the sample is placed in a hanging basket, which passes through the high temperature zone and the low temperature of the hanging basket. By moving the zone, the effect of hot and cold shocks is achieved.
The thermal shock chamber has three chambers (high temperature zone, normal temperature zone and low temperature zone). During the test, the sample is kept in the normal temperature zone, but the effect of cold and hot shock is achieved by opening and closing the damper in the high temperature zone and normal temperature zone, and the damper in the low temperature zone and normal temperature zone.
