The present invention belongs to a low-temperature waste heat generating device, wherein the generating device composed mainly of a high efficient semiconductor thermoelectric material is used for converting the low-temperature waste heat, about 100 DEG C, into electric energy directly. The generating device comprises a thermal-arrest apparatus, a bismuth telluride-based thermoelectricity power generator and a heat dissipation cooling system, and is characterized in that: the thermoelectricity power generator employs a plurality of P/N type bismuth telluride-based thermoelectricity conversion elements with high performance and is in a rectangular slice structure, wherein the plurality of thermoelectricity conversion elements are connected in series and clamped by two ceramic wafers respectively arranged on top and bottom of the thermoelectricity conversion elements, a heat-conducting silica gel sheet is adhered ton the top ceramic wafer, the thermoelectricity conversion elements are interconnected through an
