Battery Liquid-cooled Test Chamber

The Battery Liquid-cooled Test Chamber can simulate drastic changes in ambient temperature and usually achieve rapid transitions between high and low temperatures to facilitate the evaluation of the reliability and stability of materials or products under these conditions.

• •Rapid heating and cooling: The efficient refrigeration and heating system design can achieve rapid heating and cooling, shortening the test time.
• •The equipment manufacturing complies with UN38.3 , UL, IEC, SAE, GB/T testing standards.
• •Multiple test modes: It can perform multiple experimental modes such as constant temperature, cycle, alternating temperature, etc., suitable for different test needs.
• •Can cooperate with unmanned automation design to save labor costs.
• •Designed and manufactured in accordance with international standards, with high reliability and stability.

The battery explosion-proof test chamber is widely used in the battery manufacturing industry, new energy vehicle industry and related R&&D laboratories.

Liquid-cooled high and low temperature integrated test chamber is a multi-functional climate test equipment, widely used in scientific research, industry and quality inspection and other fields.Common applications are as follows:

• •Electronic and electrical: Test the performance and reliability of electronic components in high and low temperature environments.
• •Material science: Evaluate the changes in physical and chemical properties of various materials under extreme temperatures.
• •Automotive industry: Used to test the weather resistance and stability of automotive parts.
• •Aerospace: Simulate the working conditions of spacecraft at extreme temperatures.

The liquid-cooled high and low temperature integrated test chamber adopts liquid cooling technology to quickly reduce the temperature through flowing liquid coolant. Compared with the traditional air cooling system, the liquid cooling method can reach the set temperature faster and maintain a stable temperature environment.

The test standards of liquid-cooled high and low temperature test chambers usually depend on the specific application field and product type of the test. The following are some common test standards and specifications that are applicable to some scenarios of high and low temperature testing:

• •ISO 16750: A test standard for automotive electronics that includes testing under temperature and humidity conditions.
• •MIL-STD-810: A U.S. military standard that provides test methods for equipment under extreme temperature conditions. Applicable to equipment in the military and aerospace fields.
• •IEC 60068-2-2: Environmental testing - Part 1: Test B: High temperature test. Again, this is an IEC standard that provides specifications for high temperature testing.
• •IEC 60068-2-1: Environmental testing - Part 1: Test A: Low temperature test. This is an International Electrotechnical Commission (IEC) standard that specifies the procedures for testing under low temperature conditions.

The above standards and test methods can be adjusted and selected according to actual needs to better meet specific test requirements.

The control system of the Sanwood test chamber adopts the world's leading software and hardware system to ensure that the test chamber operates under preset conditions, provide accurate and reliable experimental data, and help users achieve precise control and data collection of various experimental conditions.

• •Controller: It adopts the controller imported from South Korea Sanwon and the self-developed control system, which can be equipped with Siemens control system and equipped with RS232, RS485 and Ethernet communication ports.
• •Programmable control: It supports setting experimental programs, such as heating, cooling, constant temperature time, etc., and can execute multiple program settings, and supports advance reservation startup function.
• •Multiple languages are available: English, Korean, Russian, Chinese and Japanese.
• •Remote monitoring: Using network remote technology to achieve remote control, the test chamber can be monitored at any time, and the current data can be viewed through the user's PC and mobile phone, which improves the convenience of testing.

The specific control system of the test chamber will vary depending on the model. Please read the "Sanwood Environmental Test Chamber Manual" carefully before use and comply with the safety operating procedures.

The refrigeration system of the test chamber is a complex and important system. The stability of the refrigeration system is crucial to the accuracy and reliability of the test results.

• •Sanwood Technology has developed a refrigerant hot gas defrosting technology, which effectively melts the frost on the evaporator by injecting high-temperature and high-pressure refrigerant steam into the heat exchanger in the test chamber. This not only ensures that the evaporator does not frost, but also greatly reduces the energy consumption of the equipment.
• •The refrigeration unit adopts an internationally renowned brand.which is more efficient and energy-saving, and reduces noise.
• •Optimize the layout of the refrigeration system, and adopt VRF (refrigerant flow control) technology based on the PID cold end output principle to achieve low-temperature energy-saving operation, which can reduce energy consumption by 30% under low-temperature conditions.
• •The refrigeration system adopts a modular design, with low failure rate, few welding points, high refrigeration efficiency, good reliability, simple maintenance, and low maintenance cost.
