The 3-zone thermal shock test chamber serves as core equipment for reliability testing of industrial materials and components. It is widely applied to high-low temperature alternating tests for metals, plastics, rubber, electronic components and other materials. It can quickly detect physical deformation, cracking, debonding and chemical property changes of specimens caused by rapid thermal expansion and cold contraction, and is essential equipment for enterprise R&D, quality inspection and type tests.

As a professional original manufacturer of environmental test equipment, Chongqing Wanwei Instrument mainly provides the WV-LC series 3-zone thermal shock test chamber. The equipment strictly complies with GB/T 2423.22 for temperature shock test, GB/T 10592-2023 Technical Conditions for High and Low Temperature Test Chambers, and GJB150 series military environmental test standards, fully meeting the standardized testing requirements of laboratories in various industries.

At present, mainstream thermal shock equipment on the market falls into two structures: 3-zone type and 2-zone type, adapted to different test scenarios:

Working Principle of 3-Zone Type The equipment consists of three independent cavities: heat storage zone, cold storage zone and test zone. During operation, the dual cavities continuously store heat and cold at constant temperature. Test samples are fixedly placed in the test zone without movement. Electric control dampers rapidly switch hot and cold air ducts to allow hot and cold airflows to alternately rush into the cavity to complete rapid temperature shock. It delivers stable test results and avoids sample displacement damage, ideal for high-precision and high-stability test scenarios.

Working Principle of 2-Zone Type This equipment only has a high-temperature chamber and a low-temperature chamber without an independent test zone. Samples are placed in a movable basket. A motor drives the basket to quickly switch between high and low temperature cavities. Thermal shock is realized through spatial displacement of samples. Featuring simple structure and fast temperature change rate, it fits conventional batch tests.

Chongqing Wanwei WV-LC series thermal shock test chambers are fully configured. The standard temperature range is -40℃～+150℃, and wide temperature range of -70℃~+180℃ can be customized and upgraded. Full volume models are available: WV-LC 50L, 80L, 100L, 150L, 225L, 408L, suitable for specimens ranging from small samples to large components.

The chamber adopts an all-stainless steel inner tank, which is corrosion-resistant and anti-aging, capable of withstanding repeated alternating cold and hot working conditions for a long time. Equipped with an intelligent touch control system, it supports multi-segment program customization, data storage & export and test curve tracing. Customization of non-standard sizes and special temperature zones is available to meet personalized test requirements of enterprises.

This series of equipment is widely used in electronic components, PCB circuit boards, chip connectors, rubber & plastic products, metal hardware, auto parts, new energy accessories, LEDs, communication equipment and other fields. It is the core testing device for high-low temperature shock reliability verification of industrial products.
