　　1、 The core technology of Chiller semiconductor temperature control device

The Chiller (refrigeration cycle system) adopts a compressor refrigeration+circulating liquid heat exchange method, and achieves rapid temperature rise and fall with a temperature control accuracy of ± 0.1 ℃ through high-precision temperature control algorithms. Its core advantages include:

　　1. Wide temperature range coverage (-150 ℃~300 ℃)

① High temperature range (300 ℃): suitable for high-temperature processes such as semiconductor annealing and material sintering, ensuring high-temperature stability through the circulation of heat transfer oil or ethylene glycol aqueous solution.

② Low temperature range (-150 ℃): Adopting cascade refrigeration technology or direct cooling refrigeration (direct evaporation and heat exchange of refrigerant) to achieve ultra-low temperature environment, meeting the needs of semiconductor chip low-temperature testing, infrared detector manufacturing, etc.

　　2. Rapid temperature change ability

① Some Chiller devices can complete temperature changes from -55 ℃ to 150 ℃ within 10 seconds, suitable for scenarios such as chip reliability testing and material thermal stress analysis.

② Adopting a variable frequency compressor and electronic expansion valve, dynamically adjusting the cooling capacity to ensure temperature control response speed.

　　3. High precision temperature control (0.5 ℃)

① Semiconductor manufacturing requires a temperature control accuracy of ± 0.1 ℃. Chiller uses PID control algorithm+PT100/thermocouple sensor for real-time feedback to ensure process stability.

② Some devices support multi-channel independent temperature control, which can simultaneously control the temperature of different process chambers without interfering with each other.
