1. Product Name and Purpose

2. Product Features

• Robust and Insulated Chamber Structure
  • The thermal shock test chamber is constructed with a heavy-duty steel frame that provides exceptional rigidity and stability. The frame is coated with a corrosion-resistant finish to prolong its service life. The chamber is divided into two distinct compartments, a hot zone and a cold zone, each with its own independent temperature control system. The walls of the chambers are made of high-quality insulation materials, which minimize heat transfer between the zones and maintain precise temperature levels. The insulation is carefully engineered to withstand the rigors of continuous thermal cycling and prevent any external factors from interfering with the internal test environment. The chamber is also equipped with a hermetic door seal, ensuring a leak-free enclosure and consistent test conditions.
• Precision Temperature Control System
  • Each zone of the chamber features a highly accurate temperature control system. The hot zone can maintain temperatures up to 150℃ with an accuracy of ±0.5℃, while the cold zone can reach as low as -55℃ with the same level of precision. The systems utilize advanced heating elements and refrigeration units, along with PID controllers, to achieve and maintain the desired temperature settings. Temperature sensors are strategically placed within the chambers to provide real-time feedback, enabling the control systems to make rapid and precise adjustments. The ability to transition between extreme hot and cold temperatures quickly is a key feature, with a typical temperature change rate of up to 20℃ per minute.
• Versatile Sample Handling Mechanism
  • The chamber is equipped with a sophisticated sample handling mechanism that allows for easy and efficient transfer of test samples between the hot and cold zones. This can be achieved through a pneumatic or mechanical transfer system, which ensures rapid movement of samples without significant temperature equilibration during the transfer process. The system is designed to accommodate a variety of sample sizes and shapes, and can be customized to meet specific testing requirements. Additionally, the chamber can be fitted with sample holders and racks made of non-corrosive and heat-resistant materials to ensure proper sample positioning and support.
• Intuitive Control and Data Acquisition Interface
  • The equipment is equipped with an intuitive control panel and a comprehensive data acquisition system. The control panel allows operators to easily set and adjust the temperature parameters, test durations, and cycle repetitions. It provides real-time display of the current temperature in each zone, as well as any alarms or warnings. The data acquisition system records all relevant test data, including temperature profiles, temperature change rates, and any changes in the physical properties of the test samples. The data can be stored in a built-in memory or exported to external storage devices for further analysis. The system also has the ability to generate detailed test reports in various formats, such as PDF or Excel.
• Safety and Protection Mechanisms
  • To ensure the safety of operators and the integrity of the testing process, the chamber is equipped with a range of safety features. It has emergency stop buttons strategically located for immediate shutdown in case of any abnormal situation. The chamber is also protected against over-temperature and over-current conditions, with built-in safety circuits that automatically cut off power if necessary. Additionally, the chamber is designed to prevent any refrigerant leaks, and it has a ventilation system to ensure the removal of any potentially harmful gases. The door of the chamber is interlocked, preventing it from being opened during a test cycle to avoid sudden temperature changes and potential hazards.

3. Specific Parameters

• Maximum Temperature Swing
  • The chamber can achieve a maximum temperature swing of 205℃ (from -55℃ to 150℃). This wide temperature range allows for the simulation of the most extreme thermal conditions that products may face. For example, in aerospace applications, components may experience rapid temperature changes during flight, such as when transitioning from the cold upper atmosphere to the hot engine compartment. Testing within this temperature swing helps to identify potential issues related to thermal expansion and contraction, ensuring the reliability of critical aerospace systems.
• Temperature Change Rate
  • As mentioned, the temperature can change at a rate of up to 20℃ per minute. This rapid rate of change is essential for accurately simulating real-world thermal shock events. In the electronics industry, for instance, components may be exposed to sudden temperature changes when a device is powered on or off, or when it is moved from a cold storage environment to a warm operating environment. By testing at this rate, manufacturers can evaluate the ability of electronic components, such as circuit boards and semiconductors, to withstand thermal stress without failure.
• Testing Volume and Payload Capacity
  • The chamber offers a customizable testing volume, with options ranging from 1 m³ to 20 m³. The payload capacity can be adjusted according to the size and weight of the test samples, with a maximum capacity of up to 1000 kg. This flexibility allows for the testing of a wide variety of products, from small electronic modules to large industrial components. For example, in the automotive industry, it can be used to test the durability of engine parts, transmission components, or even entire vehicle subsystems.
• Temperature Uniformity
  • The chamber ensures excellent temperature uniformity within each zone. The temperature variation within the hot zone and the cold zone is typically within ±1℃. This level of uniformity is crucial for obtaining accurate and reliable test results, as it ensures that all parts of the test sample are exposed to the same temperature conditions. In applications where precise temperature control is essential, such as in the testing of sensitive electronic components or high-precision optical devices, this feature is of utmost importance.
• Dwell Time Accuracy
  • The chamber can maintain the specified dwell times at different temperature levels with an accuracy of ±1 minute. Dwell time is an important parameter in thermal shock testing, as it determines the length of time the product is exposed to a particular temperature. Accurate control of dwell time ensures that the test is conducted in accordance with the defined test plan and provides consistent results. For example, in testing the reliability of a new material, the dwell time at extreme temperatures can help to assess its long-term stability and resistance to thermal degradation.

4. Product Functions

• Accurate Simulation of Thermal Shock Conditions
  • The primary function of the chamber is to provide a precise and reliable simulation of thermal shock conditions. By subjecting samples to rapid and extreme temperature changes, it allows manufacturers and researchers to evaluate the performance and durability of products. This is invaluable for industries where product reliability is essential, such as aerospace and defense, as it helps identify potential failure modes and allows for design improvements. For example, in the testing of satellite components, thermal shock testing can reveal weaknesses in materials or joints that could lead to failure in the harsh space environment.
