Abstract

The project is basically to build an appropriate circuit for solid state thermoelectric cooler or heater. The circuitry is used to control the connection in coldmode and hot mode. The peltier device is fabricated by combining the standard n- and p- channel semiconductor material with a two-element field emission device inserted into each of the two channels to eliminate the solid-state thermal conductivity. In general, two important components building up the thermoelectric cooler or heater is the temperature controller using a microcontroller and peltier device that consists ofanntype and p-type semiconductors of bismuth-telluride (Bi Tei) connected by H-bridge circuitry. Both elements must be connected in such a way as to produce a heat sink and heat source that are portable and using small amount of power in the atmosphere of a car. For the microcontroller to work, a specific program is loaded and programmed inside thememory of the PIC 16F877. Theobjectives of this project are to have theoretical review on thermoelectric devices, search and learn the method of developing the device. The activities are mainly focused on design and simulation. All findings and the detailed analysis including key elements of the project, which is to decide the parameters, and the design procedure that should be used, will be conducted as to follow the overall concept ofthe project.
