Thermoelectric element cooling device and refrigerator comprising same

Abstract

Disclosed is a thermoelectric element cooling device including: a thermoelectric element having an endothermic surface and an exothermic surface; a first heat dissipation plate connected to the endothermic surface and configured to dissipate heat to the endothermic surface; a first heat exchanger configured to transfer heat to the first heat dissipation plate; a second heat dissipation plate configured to dissipate heat received from the exothermic surface to a second heat exchanger; the second heat exchanger configured to release heat received from the second heat dissipation plate to the outside; and a thermoconductive member disposed at at least one position between the endothermic surface of the thermoelectric element and the first heat dissipation plate or between the exothermic surface and the second heat dissipation plate, wherein the thermoconductive member has: one side in contact with one of the surfaces of the thermoelectric element; and the other side in contact with the first heat dissipation plate or the second heat dissipation plate, the thermoconductive member includes a plurality of anisotropic, thermoconductive fillers, and at least one of the plurality of anisotropic, thermoconductive fillers is located adjacent to the one side and the other side.
