A Thermoelectric Pan for Heating and Chilling Application
Abstract
This research is a development of the thermoelectric pan which is capable of
both heating and chilling on a single pan. This thermoelectric pan is composed of six
thermoelectric modules as a source of hot and cold temperature. A heat exchanger is
installed on one side of each thermoelectric module, whereas a steel plate attaches to the
other side working as a heat/ cold pan. The dimension of the pan is 30 x 40 x 0. 8 cm
approximately. The heat exchanger receives heat from thermoelectric modules and
transfers it to water in the system, then the water circulates through a radiator passing
heat to surroundings with a fan in order to increase its efficiency. The main control system
consists of microcontroller circuits to manage relays to turn on/ off or to switch the
terminals of power supplies. The thermoelectric pan have three modes of operation; 1) Hot
mode, the thermoelectric pan can reach maximum temperature at 107 C by consuming
360 W maximum power, 2) Warm mode, the thermoelectric pan can generate temperature
at 79 C for 250W power consumption and 3) Cold mode, the thermoelectric pan can
lower temperature to minimum at 14 C taking 300W operating power.
