ABSTRACT:
Disclosed herein is a heat generating device formed of heat generating diaphragm plates comprises an electrically conducting supporting frame and a plurality of heat generating diaphragm plates. The supporting frame consists of two coupled supporting plates facing against each other with a predetermined spacing, surfaces on the two supporting plates opposite to each other are respectively provided with several insertion slots whose wall surfaces are coated to form electrode terminals such that when the heat generating diaphragm plates are inserted into the insertion slots, an electrical connection is formed among silver solders provided at both terminals of each heat generating diaphragm plate and the electrodes formed on the insertion slots thereby completing a heat generating device capable of adjusting heat generation capacity.
