Thermal shock test chamber and thermal cycling test chamber are common temperature test chambers used to test the reliability of products in extreme temperature environments. So how to choose these two temperature test chambers?
Introduction of Thermal Shock Chamber and Thermal Cycling Chamber
The product is tested in a continuously changing temperature environment that reaches extremely high and low temperatures in an instant. Thermal shock chamber has two types.
The two zones thermal shock test chamber uses the hanging basket to run between the high temperature chamber and the low temperature chamber, so as to achieve the effect of temperature shock. There is a test area between the high temperature chamber and the low temperature chamber of the three zones thermal shock test chamber, and the product undergoes thermal shock test in the test area.
Under the conditions of rapid temperature change or gradual change, the product is tested in the range of high and low temperature.
Why do Thermal Shock or Thermal Cycling Test?
Materials such as plastics, metals, and electronic equipment may deform or melt due to extreme high temperatures, or crack due to extreme low temperatures, which will eventually lead to product failure. Therefore, doing thermal shock and thermal cycling tests can help us understand the adaptability of products in different temperature environments, find problems in advance, and improve product performance.
Difference between Thermal Shock Chamber and Thermal Cycling Chamber
The biggest difference between thermal shock test chamber and thermal cycling test chamber is the speed of temperature change. The temperature change of the thermal shock test chamber is sudden and instantaneous, and there is no process of temperature change. The temperature of the thermal cycling test chamber changes gradually, which is more gentle than the thermal shock test chamber. In addition, the thermal shock test chamber has two chambers and three chambers to choose from, and the thermal cycling test chamber is mainly single chamber.
Generally, thermal shock test chambers are applied to products that may be affected by sudden temperature changes during actual use, such as brake pads, which experience sudden changes in temperature when hot brake pads pass through a puddle of water on the road. The thermal cycling test chamber is suitable for testing products that may fail due to changes in the ambient temperature or product temperature during the product’s service life.
Finally, no matter whether you choose thermal shock test chambers or thermal cycling test chambers, you must combine the product application to confirm the test requirements. If you have any other questions, please contact KOMEG.
