This study aimed to investigate the effects of the direction and flow rate of air in the heat sink to the performance of the thermoelectric coolers (TEC). A ribbed heat sink is placed on the cold side of the TEC as a heat exchanger component in the Styrofoam cooler box, while a water block placed on the hot side of TEC, the temperature, and flow rate of coolant is maintained constant. Airflow on the heat sink in the cooling room has been varied by two different types of fan modes; blowing and sucking. Air velocity is also varied for both flow conditions. The investigation showed that the sucking mode of fan at the lowest speed of airflow would generate the lowest temperature of the cooler compared with the other combinations of fan modes and speed of airflows. Based on these results, showed that the fan mode and velocity of an airflow across the heat sink affect the thermoelectric performance.
