Improvement of thermal performance of thermoelectric cooling system with nanofluids

Thanks to the tools in technology, electronic consumables can be used. Along with these devices, it also brought problems such as heating of the devices while working. This is also the case with the thermoelectric element peltier. Peltier is a thermoelectric element that is hot on one side and cold on the other. If there is no effective cooling for the hot side, this will also affect the cold surface and even the peltier may deteriorate. To avoid this and to see how much the peltier could cool the chamber, a series of experiments were carried out. Pure water and SiO2 were used as refrigerants in Peltier cooling. The proportions of nanoparticles used for nanofluid were determined as 0.25%, 0.5% and 1%, respectively. Experiments were also carried out in the electrical power of the peltier and the cooling chamber of different volumes, along with the varying volumetric ratios in the nanofluid. The electrical power of the Peltier (thermoelectric element) was determined as 6V, 8V, 10V and 12V. While the mass flow rate of nanofluid was determined as 6, 10 and 14 g/s, the volume of the cooling chamber was determined as 38×30×13 cm and 26×20×12 cm.
