Installing a 220l Thermal Shock Chamber at Etion Create

Jan 28, 2025 | Test Chamber, Testing

At Xtemp Environmental Testing, we are excited to announce the recent installation of a Climats Thermal Shock Chamber at our esteemed client, Etion Create. As a leading manufacturer of electronic components, Etion Create places a premium on quality and reliability in every product they produce. The addition of the thermal shock chamber marks a significant step forward in their commitment to enhancing quality control processes.

A 2-cabinet thermal shock chamber operates by utilizing two separate compartments, each designed to maintain extreme temperatures—one for high temperatures and the other for low temperatures. The testing process begins by placing the specimen in the first cabinet, where it acclimates to the high temperature. Once the set period is completed, the chamber automatically transfers the specimen into the second cabinet, where the temperature rapidly drops. This swift transition between extreme thermal conditions creates a thermal shock effect, effectively simulating the drastic temperature changes that materials might experience in real-world applications. This rapid cycling through hot and cold environments helps to uncover potential weaknesses in the materials, ensuring that they can withstand harsh conditions and perform reliably throughout their lifecycle.

Cold cabinet temperature range – 80 °C to + 180 °C 
Hot cabinet temperature range + 50 °C to + 180 °C 
Temperature regulation stability ± 0,1 °C to ± 0,5 °C 
Temperature homogeneity ± 0,5 °C to ± 2 °C 

Safety is a paramount concern in the operation of a 2-cabinet thermal shock chamber, and advanced safety systems are integrated to protect users during testing. One of the key safety features is the door locking mechanism, which ensures that the chamber doors remain securely closed while temperature changes are occurring. This locking mechanism prevents accidental openings during operation, eliminating the risk of exposure to extreme temperatures or potential injury. Additionally, the chamber is equipped with safety interlocks that automatically disable the heating or cooling functions if the doors are not properly sealed, thereby enhancing user protection. These safety systems are designed to provide peace of mind, allowing operators to focus on their testing procedures without compromising on safety, ensuring a secure environment for both personnel and the equipment being tested.

Utilising a chilled water supply for the refrigeration system of a 2-cabinet thermal shock chamber significantly enhances efficiency and sustainability in temperature control operations. By circulating chilled water through the system, the chamber can achieve rapid cooling rates while consuming less energy.

The strategic placement of electronic cards within the basket that moves between the two chambers of a thermal shock chamber is critical for ensuring effective testing and maximizing efficiency. When preparing for a thermal shock test, technicians carefully arrange the electronic cards in the basket, considering factors such as airflow and heat transfer. This thoughtful positioning allows for optimal exposure to the temperature extremes in both chambers, ensuring that all surfaces of the cards are uniformly subjected to the thermal conditions.

After conducting tests in a thermal shock chamber, a comprehensive test report is generated, encapsulating vital data and insights. This report serves as a valuable tool for engineers and quality assurance teams, offering a detailed analysis of the test conditions, such as the specific temperature ranges and duration of exposure, as well as the number of cycles the components underwent between the extreme temperatures.
