Abstract
A peltier device comprises peltier elements specified in cooling or heating temperature, a heating heat sink connected in contact on one side surface of the peltier element, a chilling heat sink connected in contact on the other side surface of the peltier element, and a cooling fan. Using peltier elements each of which is specified in a cooling or a heating activity, a heat exchange efficiency is enhanced thank to a plurality of functions of a single peltier element; thermal radiation is separated by bringing the peltier element into contact with a heating heat sink and a cooling heat sink independently from each other; the surface area in contact with the fluid is maximized through the “X” shaped aperture formed with four wings protruding from the inner surface of the aperture towards the center part, directly transferring the endothermic and exothermic effects from the Peltier element to the fluid.
