Design and Development Heat Dissipation Systems for Thermoelectric Coolers

Air conditioner (AC) systems present a big challenge for the environment because of the electricity demand. This paper investigates AC system designs to meet the environmental requirement of less power demand and improving efficiency. In this work, a novel heat dissipation system is designed and built to enhance the efficacy of the thermoelectric cooler (TEC) AC systems. The new heat dissipation system is based on liquid-cooling system, where a new water block is designed to make a direct connection between the hot side of the TEC and the coolant (water) by integrating the hot side of the TEC module into the water block. The system performance of this novel water-cooling system is compared and analyzed with the traditional cooling systems that are air-cooling and liquid-cooling systems. Experiments and different test profiles are conducted to analyze the system performance of the traditional and novel cooling systems with respect to power consumption, efficiency, and output response specifications. The experimental results indicate that the coefficient of performance (CoP) of the novel heat dissipation system is higher than the CoP of the traditional air-cooling and the traditional liquid-cooling system systems by 44.7% and 26.3%, respectively. The traditional liquid-cooling system consumes the highest electric power in comparison to the air-cooling system and novel liquid-cooling system. The largest temperate difference is achieved using the novel cooling system with respect to the same ambient temperature.
