STUDY AND OPTIMIZATION OF A PELTIER COOLING SYSTEM APPLIED TO ELECTRONIC SYSTEMS

Abstract

Industrial systems, particularly in the field of electronics and energy, are becoming more and more miniaturized and release heat which can degrade their operation mode and also their lifespan. It is therefore necessary to cool them. To improve these various problems listed above, an efficient heat evacuation system is made. This is cooling using a Peltier effect module, the main purpose is to produce cold when a current passes through it. TEM selection and design were made for optimizing the cooling system. The element to be cooled is carried on the cold side of the module such that the module dissipates the heat produced by this element; according to the experience made, the temperature dropped from the initial temperature which was around 30°C to a lower temperature of around 10°C and rose slightly within the hot side to be stabilize at around 36°C. A heatsink using fan is placed on the hot side of the module. 32W were dissipated using the module. For a COP value of 0.6 and knowing that the theoretical COP of a refrigerating system is between 0.4 and 0.7; it proves the performance of the cooling system tested because it corresponds to the theoretical interval (0.4<0.6<0.7).
