Three-zones Thermal Shock Test Chamber

The three-zones thermal shock test chamber is mainly composed of three parts: high temperature zone, low temperature zone and test zone. The sample is placed in the test area to remain stationary, avoiding the mechanical impact that may be caused by the sample movement.

• •Independent high-temperature, low-temperature, and intermediate conditioning chambers provide enhanced testing flexibility and reduced thermal stress on transfer mechanisms.
• •Optimized insulation and recovery systems minimize energy consumption during rapid cycling operations.
• •Meets requirements for MIL-STD-202, IEC 60068-2-14, AEC-Q100, and other rigorous thermal shock protocols.
• •Remote control and monitoring on mobile phones, tablets and PCS.

The three-zones thermal shock test chamber ideal for vibration-sensitive measuring instruments and sensors, as well as energized samples.

The three-zones thermal shock test chamber is a kind of special environmental test equipment, which can quickly test items under extreme temperature conditions. Its application areas are very wide, the following are some common application areas:

• •Automotive industry: Testing the performance and reliability of automotive components, vehicles, and materials in cold and high temperature environment.
• •Aerospace industry: Testing the performance and reliability of aerospace equipment and devices under extreme temperature conditions to ensure their reliability during spaceflight.
• •Electronic components industry: Testing the performance and reliability of electronic components in cold and high temperature environment to ensure their reliability under various environmental conditions.
• •Machinery and equipment industry: Testing the performance and reliability of machinery and equipment in cold and high temperature environments to ensure its reliability in industrial production.

The three-groove thermal shock test chamber is required to simulate the temperature change in the actual use environment, evaluate the performance, reliability and durability of the item.

Sanwood's three-zone chamber architecture addresses the growing need for more sophisticated reliability testing methodologies. By incorporating an intermediate conditioning zone, we provide manufacturers with unprecedented control over test parameters, enabling more accurate simulation of real-world operating conditions and more efficient failure analysis.

• •IEC 60917: Modular order for the development of mechanical structures for electronic equipment practices.

The two-zone thermal shock test chamber also complies with testing standards such as IEC 61587-1, IEC 60601-1,IEC 60335-1, IEC 60721, etc.

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 optional: 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.
• •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.
