1. Product Name and Purpose

2. Product Features

• Robust and Insulated Chamber Structure
  • The walk-in chamber is constructed with a heavy-duty, aerospace-grade alloy frame and insulated walls. The alloy frame provides exceptional strength and rigidity, ensuring the chamber can withstand the rigors of continuous and long-term testing. The insulation materials are carefully selected to minimize heat transfer and maintain highly accurate temperature and humidity gradients within the chamber. The chamber is sealed with advanced, high-temperature and corrosion-resistant gaskets and precision sealing mechanisms to prevent any air leakage, which could compromise the integrity of the test environment. The door is equipped with a reliable locking system and a large, pressure-resistant viewing window, allowing operators to closely monitor the test process without disturbing the internal conditions. The interior of the chamber is designed with smooth, easy-to-clean surfaces to prevent any particulate or contaminant buildup that could affect the test results.
• Precision Temperature and Humidity Control System
  • The heart of the chamber lies in its advanced temperature and humidity control system. It can achieve a wide temperature range, typically from -70°C to +120°C, with an accuracy of ±0.3°C. The humidity control range extends from 5% to 95% relative humidity, with an accuracy of ±2% RH. The system utilizes high-performance refrigeration units, electric heaters, humidifiers, and dehumidifiers, all coordinated by a sophisticated PID controller. Temperature and humidity sensors are strategically placed throughout the chamber, providing real-time feedback, enabling the control system to make instantaneous and highly accurate adjustments. The system is also designed to handle rapid temperature and humidity transitions, mimicking the sudden changes that aerospace components may experience during flight or ground operations.
• Advanced Airflow and Circulation Design
  • To ensure uniform temperature and humidity distribution within the large volume of the walk-in chamber, an advanced airflow and circulation design is incorporated. The system consists of multiple high-capacity fans and a network of ducts and baffles. The fans can generate adjustable air velocities, typically ranging from 1 m/s to 5 m/s. The airflow is carefully directed to eliminate any stagnant areas or temperature/humidity gradients, ensuring that all parts of the test samples are exposed to the exact same environmental conditions. This is crucial for obtaining accurate and reliable test results, especially when testing large and complex aerospace assemblies.
• 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 adjust the temperature, humidity, test duration, and other parameters 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 and humidity histories, rate of change of environmental parameters, 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 aerospace 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 are non-reactive with the test environment and do not contaminate the chamber. This flexibility allows for the testing of different products, from small avionics components and connectors to large aircraft wings or engine nacelles. For example, an aircraft wing section can be mounted on a specialized fixture to evaluate the integrity of its composite materials and joints under different temperature and humidity stresses, while a set of avionics circuit boards can be placed on a rack to test their performance and reliability in a humid and temperature-variable environment.

3. Specific Parameters

• Maximum Temperature Swing and Accuracy
  • With a temperature range spanning from -70°C to +120°C, the chamber can achieve a maximum temperature swing of 190°C. The accuracy of ±0.3°C ensures that the test conditions are precisely maintained, providing reliable and repeatable results. This wide temperature spectrum is essential for testing aerospace components that may be exposed to the frigid temperatures of the upper atmosphere or the heat generated during engine operation or re-entry. For example, a satellite component may need to be tested at extremely low temperatures to ensure its proper functioning in space, while a jet engine part may require high-temperature testing to evaluate its thermal stability.
• Humidity Range and Rate of Change Accuracy
  • The humidity range of 5% to 95% RH, with a rate of change accuracy of ±2% RH, allows for a comprehensive evaluation of the effect of moisture on aerospace products. The ability to precisely control the humidity level and its rate of change helps in understanding how components respond to different moisture environments, such as the condensation that may occur during rapid altitude changes or the humid conditions in tropical airports. This is crucial for ensuring the integrity of electrical systems, preventing corrosion of metal parts, and maintaining the performance of composite materials.
• Testing Volume and Payload Capacity
  • The chamber offers a customizable testing volume, with options ranging from 10 m³ to 100 m³. The payload capacity can be adjusted according to the size and weight of the test samples, with a maximum capacity of up to 5000 kg. This allows for the testing of a significant number of samples or larger and heavier aerospace assemblies. For example, a complete aircraft fuselage section or a large rocket engine can be accommodated in a suitably sized chamber, enabling comprehensive testing of these critical components.
• 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, humidity, and other environmental parameters. The resolution of the temperature data is 0.1°C, the humidity data is 0.1% RH. 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 and durability.

4. Product Functions
