The selection of environmental simulation chambers varies according to different test scenarios. For example, in laboratories and R&D departments, benchtop environmental chambers are widely used because of their small footprint and flexible operation. Understanding temperature and humidity control in benchtop environmental chambers has also gradually become a sub-topic of concern in the industry.
Environmental simulation chamber plays a very important role in all walks of life. It tests the performance and durability of products by simulating the temperature, humidity, light, vibration, salt spray and other environments in the natural environment in a controlled environment. But faced with so many environmental simulation chamber brands, many customers don’t know how to choose the right environmental simulation chamber for his industry.
So, how can we choose the most suitable environmental simulation chamber? In this article, we will introduce the information that customers need to collect when choosing the right environmental simulation chamber. in addition, if you want to know more about the common customization directions in the current industry, welcome to read the article "Top Customization Requests for Environmental Simulation Chambers" as a supplementary reference for this topic.
Learn about test product information 1. Sample name and material
Please provide the name, category and main material composition of the sample to be tested (such as metal, plastic, rubber, composite material, etc.). Note that if the product design is confidential, only the material type and basic purpose need to be stated. For example: "metal electronic components" or "plastic housing components".
2. Size, weight, quantity and shape of test samples
First, the size of the test sample (length × width × height) is the key factor in selecting the size of the environmental simulation chamber space. Especially for customers who need to test batch samples and large-volume samples, it is necessary to ensure that there is enough space in the environmental simulation chamber. Secondly, the weight of the sample is directly related to the load-bearing capacity of the tray, bracket and stage. If there are many samples and the number is large, special attention should be paid to the load-bearing design and safety stability of the equipment.
In addition, you also need to clarify whether the test is for a single sample or you want to test many samples at one time, which will affect the layout design, airflow distribution and data collection method of the equipment. For samples with irregular shapes, such as curved structures, sharp corners and hollow structures, they may affect the uniformity of airflow circulation in the chamber, thereby affecting the distribution of temperature and humidity. Therefore, it is recommended that you provide a structural diagram or a photo of the actual object before customization so that the manufacturer can optimize the airflow design.
3. Whether the sample needs to be powered on for testing
During the test, please confirm whether the sample needs to be powered on (i.e., performance testing is performed in the powered state). If the sample needs to be powered on, please provide detailed electrical parameters, including the required voltage level (AC or DC), current type, maximum power and frequency. These parameters will directly affect the electrical wiring design, power interface configuration and safety protection measures inside the test chamber. At the same time, live testing may involve electromagnetic compatibility requirements and special control requirements.
4. Does the sample generate heat during the test
If the sample is powered on or generates heat itself during the test, please estimate and provide its heat generation power. Because the heat of the sample will affect the stability and uniformity of the temperature and humidity inside the test chamber. If the heat generation is relatively large, it is necessary to consider additional configuration of heat dissipation devices and airflow adjustment systems to ensure accurate control of environmental parameters.
5. If there are other ancillary products (such as carts, shelves), weight and size must be provided
If other ancillary products (such as carts, shelves, etc.) are required during the test, please be sure to provide their accurate weight and size parameters. This information is crucial for the internal space layout, load-bearing capacity and safety protection configuration of the environmental simulation chamber.
Understanding environmental simulation chamber types 1. High and low temperature test chamber
High and low temperature test chamber is an environmental simulation equipment widely used in electronics, automobile, aerospace and other industries to evaluate the adaptability of products under extreme high temperature, low temperature and temperature alternation conditions. The equipment can achieve precise temperature control and cycle programming to help users verify the thermal stability, electrical performance and structural integrity of materials.
2. Constant temperature and humidity test chamber
Programmable constant temperature and humidity test chamber is also known as high temperature and humidity alternation test machine or constant temperature bath. It is mainly used to simulate the harsh high temperature or humidity environment that electronic instruments, new materials, electrical engineering, vehicles, metals, electronic products, aerospace materials, etc. may encounter during transportation, storage and use; or in high temperature and humidity alternation environment, test the high temperature resistance, humidity resistance and possible damage life reduction of materials, accessories or instruments and equipment.
3. Rapid temperature change test chamber
The rapid temperature change test chamber is a test equipment specially used to simulate the rapid switching between high temperature and low temperature, mainly to evaluate the thermal adaptability of products under temperature changes. Compared with ordinary high and low temperature test chambers, it has a higher heating and cooling rate (usually up to 5~15℃/min or more), and is suitable for electronic devices, automotive electronics, aerospace, new energy and other industries.
4. Thermal shock test chamber
Thermal shock test chamber (such as a three-chamber thermal shock test chamber) is used to test the degree to which materials or composite structures can withstand continuous high and low temperature environments in an instant, so as to test the chemical changes or physical damage caused by thermal expansion and contraction in the shortest time. Applicable objects include lithium batteries, metals, plastics, rubber, electronics and other materials, which can be used as a basis or reference for product improvement!
5. Walk-in test chamber
The walk-in test chamber (such as a walk-in high and low temperature humidity test chamber) is a large-scale enterable environmental simulation equipment, which is suitable for reliability tests such as high and low temperature, constant temperature and humidity, and temperature cycling for large-volume and complete products. This equipment has many advantages, such as large test space, strong customizability, and easy operation and observation by experimental personnel. It is widely used in new energy vehicle battery packs, vehicle parts, communication cabinets, aviation equipment, large industrial groups and other fields.
Key selection factors
When selecting an environmental simulation chamber, companies should consider the following key selection factors based on their product application scenarios, test standards, and budget requirements to ensure that the equipment can stably and efficiently support daily testing work.
1. Performance parameters
The performance of the equipment directly determines the accuracy and representativeness of the test. The first thing to pay attention to is the temperature range and humidity range to ensure that they can cover the test standard requirements.
Secondly, the heating and cooling rate is also a very important concern, especially when performing rapid temperature changes and stress screening (ESS). The faster the rate, the stronger the ability of the equipment to cope with extreme environmental conditions. The heating and cooling rate of conventional high and low temperature test chambers is generally 1~3℃/min, while the rapid temperature change type can reach 5℃/min or even higher.
Finally, you need to pay special attention to the temperature and humidity uniformity and fluctuation indicators, which determine whether the test environment in the chamber is consistent and whether it will cause test deviations to the test samples.
2. Control system and data functions
Choose a system that supports program editing and temperature and humidity control curve control, which can make your test more flexible and efficient. At the same time, if the selected environmental chamber has functions such as USB export and remote monitoring, it can also improve data management efficiency and facilitate enterprises to achieve quality traceability and remote monitoring.
3. Energy saving and maintenance cost
High-quality compressors, insulation materials and modular design help equipment save energy and reduce consumption and operate stably. Equipment with a reasonable structure saves time and effort in maintenance and parts replacement, and reduces downtime and after-sales frequency.
4. Safety protection
The test chamber should be equipped with multiple protections such as temperature overshoot, leakage, and fan overload to ensure the safety of personnel and samples. At the same time, it has sound and light alarm and remote reminder functions, so that experimental personnel can deal with abnormalities in time to prevent accidents.
5. Scalability and system compatibility
Equipment that supports functions such as lead holes, custom test interfaces, and communication protocols is more convenient for future docking with automation platforms and MES systems, and improves the flexibility and intelligence level of laboratory testing.
