Temperature Field and Refrigeration Output of Thermoelectric Arm

Abstract

Temperature field in thermoelectric arm and refrigeration output equation of a thermoelectric cooler was investigated by theoretical and experimental methods. Temperature differences between hot side and cold side were measured. Experimental data were used to prove the peak of the temperature parabola is located at hot side. The terms in refrigeration output equation can’t be explained as heat conducted from hot side to cold side and half of Joule heat respectively.
