Researching the Thermal Conductivity of Ice by a Measurement Device Based on Arduino

根据冰受热易融化的特性，基于稳态平板法，采用“冷传导”代替传统的“热传导”测量冰的导热系数。制作了基于Arduino的冰导热系数智能测量装置。该装置由温度控制系统、上铜盘恒温系统、数据收集系统等构成。数据可通过OLED屏幕实时显示，操作者手动记录并处理数据。也可通过Arduino单片机传输给计算机，计算机对数据进行处理，得出冰的导热系数。采用自制的基于Arduino的冰导热系数测量装置，研究了上铜盘的制冷温度、杂质种类和浓度以及冰的厚度对冰的导热系数的影响。
Based on the characteristic of ice melting easily when heated, using the steady-state plate method, the thermal conductivity of ice is measured using “cold conduction” instead of traditional “heat conduction”. We have developed an intelligent measurement device for ice thermal conductivity based on Arduino. The device consists of a temperature control system, a copper plate constant temperature system, a data collection system, etc. The data can be displayed in real-time through OLED screens, and the operator manually records and processes the data. It can also be transmitted to the computer through the Arduino microcontroller, making it easy for the com-puter to process the data and obtain the thermal conductivity of the ice. Using a self-made ice thermal conductivity measurement device based Arduino, the effects of the cooling temperature of the upper copper plate, the type and concentration of impurities, and the thickness of ice on the thermal conductivity of ice were studied.
