It selects the phase-change material with suitable phase transition temperature and can realize and reactor temperature is precisely controlled, concrete operating principle is as follows：
Control device preserves the reaction temperature of setting, and temperature sensor detection reactor temperature simultaneously passes the signal to control device,
When reactor temperature is less than set temperature, control device controls heating devices heat；It is set when reactor temperature reaches
When temperature, heater stop heating still has heat to discharge so that reactor temperature continues to rise, when warm in reaction kettle at this time
When degree reaches phase change layer phase transition temperature, which undergoes phase transition heat absorption so that reactor temperature keeps stablizing；For a period of time it
Reactor temperature declines afterwards, and heat release phase transformation occurs for phase-change material, to system heat release, maintains temperature of reaction kettle constant；Work as phase transformation
When material phase transformation completion system temperature continues to reduce, control device receives temperature sensor detection signal, and control heating device is opened
Begin to heat, until reaching set temperature.Above procedure persistent loop maintains reactor temperature constant.
