Abstract
We describe a study of the cooling device based on the electrocaloric effect (ECE) in multi-layer ceramic capacitor (MLC). The ECE causes increasing and decreasing temperature of a dielectric material by changing the electric field. To separate heating and cooling sequence of ECE, the heat pipe used as the thermal diode was combined with MLCs. This device demonstrated that the temperature of MLC was dropped 0.43 degrees by applying 71.5 MV/m at 0.1 Hz.
