Abstract:

The choice of coolant plays a key role in the performance of liquid cooling systems for high power heat dissipation. At present, glycol and propylene glycol coolants are the most widely used. The specific heat capacity of diol coolant with different freezing points was measured by differential scanning calorimeter. By means of Fourier transform, the heat flow signal is decomposed into heat capacity components and kinetic components by modulated differential scanning calorimetry (MDSC), and the reversible specific heat value is obtained. The relevant test results provide an important reference for the research of diol coolant.

Key words: coolant, specific heat, modulated differential scanning calorimetry, alcohol, prediction, experimental validation, mixtures

摘要:

冷却液的选择对于高功率散热用液冷系统的性能起到关键作用。目前乙二醇型和丙二醇型冷却液应用最为广泛。利用差示扫描量热仪对不同冰点的二元醇型冷却液进行了限定温度区间的比热容的测量。利用调制差示扫描量热法(MDSC),通过傅里叶变换将产生的热流信号分解成热容成分和动力学成分,得到可逆比热容值,并将实验结果进行了二次多项式的曲线拟合。相关测试结果可为二元醇型冷却液的研究提供参考和借鉴。
