A walk-in high-low temperature test chamber is a device specifically designed to simulate and test the performance of products under extreme temperature conditions. This type of laboratory is widely used in the automotive industry to evaluate the heat and cold resistance of automotive components under different climatic conditions.

The main function of a walk-in high-low temperature test chamber is to provide a controllable environment to simulate high or low temperature conditions, in order to test whether the physical and chemical properties of products will change due to temperature changes This device is not only suitable for whole machine products, but also for testing components, allowing for the simultaneous placement of a large number of test items for reliability testing, thereby reducing the total testing time for a single product.

In addition, the walk-in high and low temperature test chamber can also conduct wet heat cycle tests, which means that in addition to temperature control, humidity conditions can also be controlled to more comprehensively evaluate the performance of products under various environmental conditions This is particularly important for automotive components as they need to maintain their performance and stability under different climatic conditions.

When choosing a walk-in high-low temperature test chamber, one should consider its technical parameters, accuracy, and whether it can meet specific testing requirements. For example, some advanced laboratories may have automated control systems that can automatically adjust environmental parameters based on preset conditions to ensure the accuracy and repeatability of testing.

The technological progress in the following aspects:

• New solution: Adopting a new generation of unique testing methods, it significantly improves temperature linearity and accuracy, causing almost no temperature drop.

• Wet and hot condition simulation: It can simulate various environmental conditions, such as high temperature, low temperature, wet and hot, dry, etc., comprehensively evaluate product performance, and shorten the research and development cycle.

• Real time testing equipment: It can solve the problems of real-time imaging testing of cameras at high and low temperatures.

• Linear variation temperature (humidity) test chamber: provides more accurate and flexible temperature control capabilities.

• Controller operation optimization: Fuzzy algorithm is used for controller operation, and the parameters are adjusted reasonably to achieve the best effect. At the same time, a 7-inch TFT true color LCD touch screen is equipped to improve operation convenience.

How to choose walk-in chamber for automotive components?

Choosing a suitable walk-in high-low temperature test chamber requires comprehensive consideration of multiple factors to ensure that the equipment can meet the testing needs of automotive components under different environmental conditions. Here is a detailed purchasing guide:

• Temperature range:

Determine the required temperature range based on the specific requirements of automotive components. For example, if components need to work in extreme low temperature environments, a laboratory with a temperature range of -80 ℃ to+150 ℃ can be selected. If testing needs to be conducted within a wider temperature range, equipment with a temperature range of -70 ℃ to 150 ℃ can be selected.

• Humidity range and deviation:

If humidity factors need to be considered during testing, a laboratory with wet and hot functions can be selected. For example, certain devices can provide a humidity range of 5% to 98% RH. Ensure that the humidity control accuracy of the equipment meets the testing requirements.

• Heating and cooling rate:

The rate of temperature rise and fall is also an important parameter. Generally speaking, a heating rate of 3 ℃/min is a common choice. According to the testing requirements, select an appropriate heating rate to ensure the accuracy and reliability of the testing.

• Physical load and heating load:

Consider the load-bearing capacity of the equipment to ensure that it can withstand the weight and heat generated by the tested item. Choose a laboratory with sufficient volume and load capacity to avoid affecting test results due to overload.

• Size and Capacity:

Select equipment of appropriate size according to the requirements of the testing space. For example, if you need to test large components, you can choose a laboratory with a volume of 6m ³, 8m ³, or larger. Ensure that the size and capacity of the equipment meet the testing requirements.

• Brand and Quality:

Choose reliable brands and high-quality equipment to ensure long-term stable operation and good maintenance and service. Avoid choosing low-priced products as this may lead to quality issues and maintenance difficulties.

• Other functions:

According to the testing requirements, choose whether additional functions are needed, such as constant temperature and humidity, circulation function, etc. These features can help simulate more complex and rigorous testing environments.
