Abstract：The supply of liquid nitrogen in the low temperature mechanical spectroscopy experiment is handworked.It causes some problems,such as influences from the operators,low precision of temperature and long stability controling time. Thus an improved cryogenic cooling device is designed.It controls the sample's temperature with temperature controller and temperature sensor.The cryogenic cooling device makes the temperature stable quickly.It realizes temperature control automatically with high precision.Also,it provides a reference for other experiments which need cryogenic cooling devices.
