Abstract
Corrugated fins are provided at opposing sides of a corrugated thermoelectric device constituting a thermoelectric circuit. This air conditioner is obtained by superposing a plurality of the thermoelectric devices. When a current is fed to the thermoelectric devices, heat is absorbed from one of two fluids running through the corrugated fins and discharged to the other fluid, so as to define a heat pump cycle is defined. The thermoelectric devices are superposed so that the confronting surfaces of the neighboring thermoelectric devices constitute a heat radiation surface respectively and a cooling surface. The corrugated fins intersect with each other, so that the two fluids are prevented from mingling and are allowed to flow in and out of different surfaces.
