Abstract
The study is to understand the characteristics of different thermoelectric coolers (TEC) and analyze their performance through numerical calculations. TECs are solid-state cooling devices that operate following the Peltier effect, which can transform electric power directly into thermal power. TECs offer several advantages such as the absence of mechanical moving parts, precise temperature control ability, compact in sizes, high reliability, and intrinsically safe for hazardous electrical conditions. They are also friendly to the environment due to no chlorofluorocarbons (CFC) or any other refrigerant gases are used. In recent years, research contributions on thermoelectric materials have increased TECs' commercial value. While designing a cooling system, characteristics of TEC module are able to affect its performance. A calculation method is provided for performance prediction. The study chooses some TEC modules with distinct number and height of semiconductor pairs to estimate their behavior under different input current. The results are then compared with simulation software, differences are below 1%.
