THERMOELECTRIC UNIT AND TIMEPIECE USING IT

摘要

A thermoelectric unit having a structure of good thermal conduction efficiency, which prevents thermoelectric elements from damage due to external forces and facilitates the connection of its output with timepiece movements. Thermoelectric elements (111) are surrounded by a frame (119), which has a heat-absorbing plate (112) fixed on one side and a heat-radiating plate (118) fixed on the other side. A heat-conducting shock absorber (121) is filled or placed between the thermoelectric elements (111) and the heat-absorbing plate (112) or the heat-radiating plate (118), so that the thermoelectric elements (111) are integrated into a unit structure. Electrodes (114a) at the extreme ends of the thermoelectric elements (111) connected in series are connected to heat-absorbing plate (112) and heat-radiating plate (118) to form means for producing electromotive force.
