초록

As CPU performance increases and lithium-ion batteries are increasingly used in electric vehicles, the demand for effective thermal management has become critical. Excessive heat can degrade performance and shorten system lifespan. To address the limitations of conventional air and liquid cooling methods, this study proposes a hybrid cooling system combining thermoelectric modules (TEMs) and phase change materials (PCMs). The TEM enables active cooling via the Peltier effect, while the PCM passively absorbs heat through latent heat storage. Experimental results show that the proposed system effectively delays temperature rise and maintains thermal stability. The system also benefits from enhanced natural convection in the liquid PCM phase, providing improved heat dissipation compared to air cooling.
