The invention relates to means of heat-power engineering for power supply of units of heating systems. A thermo-electric generator for power supply of units for heating boilers comprises thermoelectric modules located between cold and hot heat exchangers, and a burner on liquid or organic fuel. The hot heat exchanger consists of individual for every thermoelectric module heat exchangers arranged one above another at lest in two horizontal lines, one of surfaces of the said heat exchangers comprises vertical ribs which situated in a flow of hot gases entering from a individual burner, a second surface has heat contact with a hot side of the thermoelectric module, a cold heat exchanger is made a basis comprising N planes from one side with thermoelectric modules located on the said planes, from the other side - cooling ribs, which has heat contact with a heat carrier circulating into a heating boiler. Number of N planes of the cold heat exchanger equals to number of utilized modules, an aria of heat receiving surface of each hot individual heat exchanger located in one horizontal line is less in 1,8-2,2 times than aria of heat receiving surface of individual heat exchanger located in the next horizontal line. The invention provides effectiveness growth of transformation of heat energy into electrical energy with reduction of mass and overall dimensions. |
