Lab Two-Chamber Thermal Shock Chamber
Nov 03, 2025
The two-chamber thermal shock chamber is a highly reliable environmental testing device specifically designed for evaluating the ability of products to withstand extreme temperature changes. It simulates harsh temperature shock conditions to rapidly expose the possible failures of materials, electronic components, automotive parts and aerospace equipment during rapid thermal expansion and contraction, such as cracking, performance degradation and connection faults. It is a key tool for improving product quality and reliability.
The core design concept of this device lies in efficiency and harshness. It has two independently controlled test chambers inside: a high-temperature chamber and a low-temperature chamber, which are respectively maintained at the set extreme temperatures continuously. The sample to be tested is placed in an automatic mechanical basket. During the test, the basket will be rapidly switched between the high-temperature zone and the low-temperature zone under the program control, instantly exposing the sample to a huge temperature difference environment, thus achieving the true "thermal shock" effect.
Compared with another mainstream three-chamber (static) impact chamber, the significant advantage of the two-chamber type lies in its extremely fast temperature conversion speed and short temperature recovery time, ensuring the strictness and consistency of the test conditions. It is highly suitable for testing samples with sturdy structures that can withstand mechanical movement, and the testing efficiency is extremely high. Its working principle determines that during the testing process, the temperature fluctuation of the high and low temperature chamber is small, it can quickly return to the set point, and is not significantly affected by the sample load.
This equipment is widely used in fields such as semiconductors, integrated circuits, national defense science and technology, automotive electronics, and new material research and development, for conducting reliability tests as required by various international standards. Its main technical parameters include a wide temperature range (high temperatures up to +150°C to +200°C, low temperatures down to -40°C to -65°C or even lower), precise temperature control accuracy, and customizable sample area sizes.
The Lab two-chamber thermal shock chamber, with its irreplaceable rapid temperature change capability, has become the ultimate touchstone for testing the adaptability and durability of products in extreme temperature environments, providing a strong guarantee for the precision manufacturing and reliability verification of modern industry.
