Air To Air Hot Cold Thermal Shock Test Machine

LIB Air To Air Hot Cold Thermal Shock Test Machine is designed to reproduce extreme and sudden temperature changes that products may face during real-world operation. It simulates rapid transitions between high and low temperatures in a controlled air environment, helping manufacturers evaluate material stability, structural integrity, and long-term reliability without using liquid nitrogen. The system is widely used in electric vehicles, aerospace components, semiconductor devices, and advanced electronic assemblies where thermal stress failure is a critical concern.

Advantages of LIB Air To Air Hot Cold Thermal Shock Test Machine

1. Ultra-Fast Thermal Transition Performance: LIB's thermal shock system is engineered to switch between extreme temperatures ranging from –75 °C to +220 °C within 3 seconds, with full system recovery typically achieved in under 5 minutes. The dual-chamber hot and cold air circulation design eliminates reliance on liquid nitrogen, ensuring safer operation and lower running cost. This rapid cycling capability makes it highly suitable for demanding applications such as EV battery validation, aerospace-grade components, and high-precision electronic devices exposed to severe thermal stress.

2. High Accuracy Temperature Control and Uniform Exposure: The system uses a closed-loop PID control architecture combined with PT100 Class A sensors to maintain temperature precision within ±1 °C. Dual high-efficiency centrifugal fans distribute airflow evenly across the chamber, ensuring consistent thermal exposure for every test sample. Operating noise is controlled at or below 65 dBA, allowing stable performance in laboratory environments while maintaining highly repeatable test conditions.

3. Adaptable Structure and Application Flexibility: The chamber is designed to support a wide range of testing configurations. Reinforced shelving systems can carry loads up to 80 kg, making it suitable for both small electronic components and larger assemblies such as battery modules. Integrated 100 mm cable ports allow powered testing and real-time signal monitoring during operation. Optional Ethernet and USB interfaces enable remote control, data acquisition, and integration into automated laboratory systems.

4. Long Service Life and Global Technical Support: Built with a SUS304 stainless steel interior and a reinforced A3 powder-coated steel exterior, the equipment is engineered for continuous industrial use over more than 10 years of service life. LIB provides a 3-year warranty, fast international shipping, and global after-sales support to ensure reliable operation and minimal downtime for customers worldwide.

5. Enhanced Safety for High-Energy Testing Applications: For lithium-ion battery and high-risk material testing, the system incorporates multiple safety mechanisms including reinforced structural housing, pressure release channels, automatic emergency shutdown, and real-time smoke detection systems. These safety features significantly reduce operational risk and comply with stringent international safety standards such as UL 2580 and UL 9540A, ensuring secure testing even under extreme thermal conditions.

Technical Parameters

Product Operate Guide

Before use, power on the thermal shock test machine and verify all connections. Set the desired hot and cold zone temperatures and cycle times on the touchscreen controller. Place samples securely on the adjustable stainless-steel shelves, ensuring even spacing and no contact with chamber walls. For battery testing, connect monitoring cables through the stainless-steel cable holes. During operation, monitor temperature, vibration (if applicable), and safety alerts. After testing, allow the chamber to stabilize before unloading samples. Regular maintenance and proper handling ensure accurate results and long-term reliability.

FAQ

Q1: How is the Thermal Shock Test Machine calibrated?

A: The thermal shock machine chamber is calibrated using 9 temperature sensors evenly distributed across the hot and cold zones. The system records each sensor’s readings and compares the average to preset standards. If deviations occur, hardware adjustments optimize temperature uniformity, ensuring accurate display and consistent environmental conditions for reliable testing.

Q2: Is an external air source required? What is its function?

A: No external air source is needed. The thermal shock machine has a built-in air supply that powers the basket elevator and rail system. It ensures smooth and safe transfer of samples between hot and cold zones during thermal shock cycles, maintaining test accuracy and protecting delicate materials or battery packs.

Q3: Can the thermal shock test machine support battery testing with live monitoring?

A: Yes. Stainless-steel cable holes allow operators to connect monitoring devices for real-time voltage, current, and temperature tracking. This feature ensures safe and accurate testing of EV battery packs, modules, or cells without compromising chamber sealing or environmental control.

Q4: How fast can the thermal shock test machine switch between hot and cold zones?

A: The basket elevator transfers samples between hot and cold zones in under 3 seconds. Recovery time to stabilize setpoints is ≤5 minutes. This rapid cycling allows realistic thermal shock simulations while meeting global standards for reliability testing.
