Abstract
A thermoelectric module,comprising p-type thermoelectric elements,and n-type thermoelectric elements,which are alternately arranged and electrically connected by electrodes,provided on the top side and the bottom side of each thermoelectric element,and a heat exchanger plate,which is fixed on the electrodes on each side, in which each thermoelectric element,has a coating film,of an insulating material on the sides thereof except the sides joined to the electrodes,, and the thermoelectric elements,are spaced apart. The coating film,improves the strength and moisture resistance of the thermoelectric elements,to prevent thermoelectric elements from cracking or breaking even in cases where a load, a shock, or a thermal stress is imposed thereon and to protect the thermoelectric elements against corrosion in a high humidity atmosphere, providing a thermoelectric module,with improved operational reliability.
