With the deepening of the national industrial upgrading strategy, the technological and cutting-edge requirements for products in the fields of new energy vehicles, motors, electronic controls, batteries, and electronic aerospace industries are increasingly increasing. In this context, the demand for simulated experimental testing has exploded in order to ensure the reliability and stability of related materials, components, functional units and systems under a variety of extreme conditions.

　　High and low temperature coolant testing machines are becoming the new darling of this wave of testing process reform. The equipment through the liquid cooling unit to the measured part through liquid heating and cooling, because the liquid directly with the measured part of the heat exchange, high heat exchange efficiency, the measured part temperature reach time quickly, thus greatly shorten the test cycle.

　　It is understood that the high and low temperature coolant tester can not only simulate a wider temperature range, rapid temperature change and higher temperature stability, but also has rapid heat transfer capability and controllable pressure and flow. This can be a comprehensive test of the heat transfer capacity of the heat exchange runner, the reliability of the system runner at different temperatures, and the ultimate operating capacity of the system runner in the actual application process.

　　The system is composed of refrigeration compressor unit, refrigeration liquid tank, temperature control, flow control, pressure control and communication module. Among them, the refrigeration compressor unit adopts the brand compressor to provide a constant cold source for the entire equipment; The cooling liquid tank is detected by temperature sensor, and its temperature is accurately controlled by temperature controller. In terms of temperature control, the system adopts imported temperature sensor and PLC controller to realize automatic temperature control of equipment temperature; The flow control and pressure control modules achieve accurate flow and pressure control through electric regulating valves and corresponding sensors.

　　Industry insiders said that the emergence of high and low temperature coolant testing machines not only provides more efficient and accurate solutions for new energy and high-end manufacturing product testing, but also promotes the technological upgrading and innovative development of the testing equipment industry. With the continuous expansion of related industries and the continuous growth of market demand, the technical competition and market competition in this field will become increasingly fierce.

　　The reporter also learned that the application range of high and low temperature coolant testing machines is constantly expanding. In addition to new energy vehicles and electronic aerospace industry and other fields, the system can also be applied to power electronics, military, scientific research and other fields. Especially in experiments that need to simulate extreme temperature conditions, the system has shown unparalleled advantages.

　　In addition, with the continuous development of technologies such as the Internet of Things and big data, the intelligent and networked upgrading of high and low temperature coolant testing machines will also become an important trend of future development. By linking with host computer and adopting RS485 communication protocol, the system can realize remote control, automatic data acquisition and analysis, and further improve the test efficiency and accuracy.

　　In general, the emergence and development of high and low temperature coolant testing machine not only ADAPTS to the requirements of high quality and high reliability of products under the national industrial upgrading strategy, but also brings new development opportunities and challenges for the testing equipment industry. Looking to the future, with the continuous progress of technology and the continuous growth of market demand, we have reason to believe that more innovative achievements and application breakthroughs will emerge in this field.
