1. Product Name and Purpose

2. Product Features

Precise Climatic Control

• Wide Temperature Range
  • The chamber is capable of achieving a broad temperature range that is highly relevant to automotive testing. It can reach extremely low temperatures, typically as low as - 70°C, which is useful for testing how the engine starts and operates in cold climates, the battery's performance in freezing conditions, and the brake system's response to icy surfaces. On the other hand, it can attain high temperatures of up to + 150°C, simulating the heat generated in the engine compartment during extended driving in hot weather, the impact of high ambient temperatures on the battery, and the brake system's ability to withstand heat during heavy braking.
  • The temperature control is highly precise, with an accuracy of ±0.5°C. This precision is essential as even small temperature variations can significantly affect the performance of these components. For example, a slight change in temperature can impact the engine's fuel combustion efficiency, the battery's charging and discharging capacity, and the brake system's friction characteristics.
• Accurate Humidity Regulation
  • Humidity levels within the chamber can be precisely regulated from 10% to 95% relative humidity. High humidity can lead to corrosion in the engine, battery, and brake components, affecting their performance and lifespan. It can also cause issues such as brake fade due to moisture absorption in the brake pads and rotors. Low humidity, on the other hand, can contribute to static electricity problems in the battery and electrical components of the engine.
  • The humidity control accuracy is usually within ±3% relative humidity. This ensures that the test environment closely replicates the real - world humidity conditions that these components may encounter, providing reliable and consistent test results.

Stable and Uniform Environment

• Uniform Climatic Distribution
  • The interior of the constant climatic test chamber is designed to provide a uniform distribution of temperature and humidity throughout the test volume. Advanced air circulation systems and multiple sensors are strategically placed to ensure that the temperature variation within the chamber is typically within ±1°C, and the humidity variation is within ±5% relative humidity.
  • For the car engine, battery, and brake system, which are complex assemblies of various components, a uniform environment is crucial. It ensures that all parts of these components are exposed to the same climatic conditions, eliminating any biases in the test results and providing a more accurate representation of their performance under real - world conditions.
• Long - Term Stability
  • The chamber is capable of maintaining stable climatic conditions over long periods. This is essential for conducting long - term endurance tests on these components. For example, an engine may need to be tested for thousands of hours under specific temperature and humidity conditions to evaluate its long - term reliability. The battery's lifespan and performance can also be accurately assessed through extended testing. The brake system's durability can be tested by subjecting it to repeated braking cycles under constant climatic conditions. The chamber's stability ensures that the test conditions remain constant throughout the test, providing consistent and comparable results.

Multiple Test Modes and Customization

• Programmable Test Profiles
  • Operators have the flexibility to create programmable test profiles that simulate the complex and variable environmental conditions that these components experience in real - world driving. These profiles can include cyclic changes in temperature and humidity to mimic seasonal variations, sudden changes to simulate extreme weather events, or custom - tailored profiles based on specific driving scenarios. For example, a test profile can be designed to simulate the temperature and humidity changes that a car experiences during a long - distance journey from a cold mountainous region to a hot and humid coastal area.
  • The ability to create customized test profiles allows manufacturers to test these components under conditions that are relevant to their intended use. This provides more accurate and meaningful test results, enabling them to better understand how these components will perform in different real - world scenarios and make targeted improvements to enhance their performance and reliability.
• Optional Test Accessories
  • The constant climatic test chamber can be equipped with a variety of optional test accessories to meet specific testing requirements. For the car engine, dynamometers can be added to simulate different load conditions, while exhaust gas analyzers can be used to measure the emissions. For the battery, charging and discharging equipment can be installed to test its performance under various electrical loads. For the brake system, brake dynamometers can be used to measure the braking force and torque, and wear sensors can be added to monitor the brake pad and rotor wear. Additionally, dust and salt - spray generators can be used to simulate the effects of dusty roads and salt - laden air on these components.

User - Friendly Operation and Monitoring

• Intuitive Control Interface
  • The chamber is equipped with an intuitive control interface that simplifies the operation process. The interface allows operators to easily set and adjust test parameters, such as temperature, humidity, test duration, and test profiles. It also provides a clear display of the current test status, including the actual temperature and humidity values, elapsed test time, and any error messages. The user - friendly design ensures that even operators with limited technical expertise can efficiently conduct tests on these automotive components.
• Remote Monitoring and Control
  • Many models of the constant climatic test chamber offer remote monitoring and control capabilities. This feature is highly beneficial for automotive manufacturers and quality control teams, as it allows them to monitor the test progress and adjust the test parameters from a remote location, such as an office or a control center. This is especially useful for long - term tests or when multiple tests are being conducted simultaneously. Remote monitoring and control enable timely intervention in case of any issues, ensuring the smooth and efficient operation of the testing process.
