eMMC High And Low Temperature Test Chamber

The eMMC high and low temperature test chamber design usually includes three levels or shelves, which can test multiple samples at the same time, which is very suitable for laboratories or production environments that require large-scale testing.

• •Advanced cold balance control mode and PD adjustment technology greatly reduce the energy consumption of the equipment.
• •After the program runs, the equipment has the function of automatically restoring normal temperature for the protection of the test product.
• •It has good sealing to ensure that the equipment can run for a long time (more than 1000 hours) without frost.
• •The unique air circulation design ensures that the top of the studio will produce dripping even in the hot and humid mode.
• •Can customized the chamber’s volume, temperature and appearance on demand.

The high and low temperature test chamber has a wide temperature control range, usually covering from -80℃ to +200℃, or even higher or lower.

The eMMC high and low temperature test chambers are mainly used to test the performance indicators of parts and materials of related products such as electronics and electrical engineering, automobiles and motorcycles, aerospace, ship weapons, colleges and universities, scientific research institutions, etc. under high temperature and low temperature (alternating) cyclic changes. It has a wide range of applications in many fields. The following are some common application areas:

• •Electronic and electrical industry: used to test the performance and reliability of electronic components, circuit boards, complete machines and other products under high and low temperature environments.
• •Automotive industry: Test the performance of automotive parts such as engines, batteries, body materials, etc. under extreme climate conditions to ensure that the car can maintain stable performance in various complex environments.
• •Aerospace industry: Test the performance of aircraft parts under extreme climatic conditions to ensure that they can work normally under various environmental conditions.
• •Scientific research field: Provide stable environmental conditions for scientific researchers for material research, biological experiments, etc.

The working principle of the eMMC high and low temperature test chamber is mainly based on cooling and heating cycles. These cycles are used to control the temperature inside the equipment to simulate different high and low temperature environments.

• •MIL-STD-810: US military standard, involving a variety of environmental tests, including high and low temperature test methods, very suitable for military and aerospace products
• •ISO 16750: An automotive industry standard that provides requirements for testing automotive electronic components under different environmental conditions, including temperature and humidity changes.
• •SAE J1211: A standard for automotive electronic components that covers reliability testing under extreme temperatures.
• •IEC 60068-2-1 and IEC 60068-2-2: Environmental testing standards issued by the International Electrotechnical Commission (IEC), respectively involving low temperature and high temperature environmental test methods, suitable for weathering tests of electronic components and equipment.

It also complies with IEC 60571, NB/T 31004, GJB 150, IEC, MIL and other test standards.

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 SAMWON-EZNET 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. In cooperation with Japan's Saginomiya and the United States' Sporlan, the EPV series and XUP series energy-saving system quick-opening solenoid valves have been developed, with an all-weather service life of more than 15 years. And began to develop a new Danfoss AKV series throttling electronic expansion valve system, 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.
