1. Product Name and Purpose

2. Product Features

• Robust and Insulated Chamber Structure
  • The test chamber is constructed with a heavy-duty steel frame and insulated walls. The steel frame provides excellent structural integrity, ensuring the chamber can withstand the rigors of continuous temperature cycling. The insulation materials are carefully selected to minimize heat transfer and maintain precise temperature gradients within the chamber. The chamber is sealed with high-quality gaskets and advanced sealing mechanisms to prevent any air leakage, which could affect the accuracy of the temperature control. The door is equipped with a reliable locking system and a viewing window, allowing operators to monitor the test process without disturbing the internal environment.
• Precision Temperature Control System
  • The heart of the chamber lies in its advanced temperature control system. It can achieve a wide temperature range, typically from -70°C to +180°C, with an accuracy of ±0.3°C. The system offers both linear and nonlinear temperature change profiles. In the linear mode, the temperature can be ramped up or down at a constant rate, which can be adjusted from 1°C per minute to 20°C per minute. In the nonlinear mode, the temperature change can follow complex curves, simulating more realistic and unpredictable temperature fluctuations. The control system utilizes high-performance refrigeration units, electric heaters, and intelligent controllers to ensure accurate and stable temperature transitions. Temperature sensors are strategically placed within the chamber to provide real-time feedback, enabling the control system to make instantaneous adjustments.
• High-Speed Air Circulation System
  • To ensure uniform temperature distribution within the chamber, a high-speed air circulation system is incorporated. The system consists of powerful fans and carefully designed ductwork. The fans can generate adjustable air velocities, typically ranging from 1 m/s to 5 m/s. The air circulation helps to eliminate temperature gradients, ensuring that all parts of the test sample are exposed to the same temperature conditions. This is crucial for obtaining accurate and reliable test results, especially when testing large or complex products.
• Intuitive Control Panel and Data Acquisition Interface
  • The equipment is equipped with an intuitive control panel that simplifies the operation and parameter setting. Operators can easily select between linear and nonlinear temperature change modes, set the temperature range, rate of change, and test duration using the user-friendly interface. The control panel also provides real-time displays of the current test conditions, as well as any alarms or warnings. The chamber is integrated with a comprehensive data acquisition system. It records all relevant test data, such as temperature profiles, rate of temperature change, and any observable changes in the test samples. The data can be stored in a built-in memory or exported to external storage devices for further analysis. The system can also generate detailed test reports in various formats, facilitating easy documentation and sharing of results.
• Versatile Sample Fixturing and Placement
  • The interior of the chamber is designed to accommodate a wide variety of sample sizes and shapes. It can be equipped with adjustable racks, trays, and custom-made holders to ensure proper positioning and exposure of the test samples. The sample fixturing is made of materials that have low thermal conductivity and do not contaminate the test environment. This flexibility allows for the testing of different products, from small electronic components to large automotive parts or aerospace assemblies. For example, a printed circuit board can be mounted on a holder to test its resistance to rapid temperature changes, while a car engine block can be placed on a rack to evaluate its durability under extreme thermal stress.

3. Specific Parameters

• Temperature Range and Accuracy
  • With a temperature range of -70°C to +180°C and an accuracy of ±0.3°C, the chamber can subject products to a wide spectrum of temperature extremes. This is essential for testing products that may be used in arctic or desert environments, or in applications where high heat is generated, such as in industrial ovens or electronic components near heat sources. The accurate temperature control ensures that the test conditions are precisely maintained, providing reliable and repeatable results.
• Linear Temperature Change Rate Range
  • The adjustable linear temperature change rate from 1°C per minute to 20°C per minute allows manufacturers to simulate different rates of temperature change that products may experience. A slower rate may be used to evaluate the long-term effects of gradual temperature shifts, while a faster rate can test the product's ability to withstand sudden thermal shocks. For example, an electronic device may need to be tested at a slower rate to assess its performance during seasonal temperature changes, while a military equipment component may require a rapid temperature change rate to simulate battlefield conditions.
• Nonlinear Temperature Profile Capabilities
  • The ability to create nonlinear temperature profiles is a unique feature of this chamber. It can mimic complex temperature fluctuations that occur in real-world scenarios, such as the temperature changes experienced by a product during a flight (where it may be exposed to different altitudes and external temperatures) or in a manufacturing process where the temperature is not linearly controlled. This allows for a more comprehensive evaluation of a product's performance under unpredictable temperature conditions.
• Testing Volume and Payload Capacity
  • The chamber offers a customizable testing volume, with options ranging from 0.5 m³ to 10 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 allows for the testing of a significant number of samples or larger and heavier products. For example, in the automotive industry, multiple car parts or even a complete vehicle can be tested in a larger chamber, while in the electronics industry, a batch of small devices can be tested simultaneously in a smaller chamber.
• Data Sampling Frequency and Resolution
  • The data acquisition system samples data at a frequency of up to 200 Hz, providing a highly detailed record of the temperature changes. The resolution of the temperature data is 0.1°C. This high-resolution data is invaluable for identifying even the slightest trends and potential failure points, allowing for a more accurate assessment of product performance.

4. Product Functions

• Accurate Simulation of Linear and Nonlinear Temperature Changes
  • The primary function of the chamber is to provide a precise and reliable simulation of both linear and nonlinear temperature change conditions. By subjecting products to controlled temperature profiles, it allows manufacturers and researchers to evaluate their thermal resistance and durability. This is crucial for ensuring the reliability of products such as smartphones, satellites, and industrial machinery, as it helps identify potential failure modes and allows for design improvements. For example, testing a satellite component's ability to withstand the nonlinear temperature changes during its orbit can ensure its proper functioning in space.
• Product Design Optimization and Quality Control
  • Through a series of tests on different product prototypes, the data obtained from the chamber can be used to optimize product designs. Engineers can analyze the behavior of various materials and components under rapid temperature changes and make modifications to enhance the overall performance and reliability. The chamber also serves as a vital tool for quality control, ensuring that each batch of products meets the required temperature resistance standards. For instance, in the manufacturing of automotive sensors, testing in the rapid temperature change chamber can help detect any weaknesses in the sensor's calibration or housing, leading to improvements in product quality.
