Specific heat of diol coolant determined by modulated differential scanning calorimetry
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.
