ENERGY RECOVERY FROM WASTE HEAT
An apparatus for waste heat recovery is provided. The apparatus includes a base block disposed adjacent to a heat source, a thermoelectric generator including a first end and a second end, the first end being thermally coupled to the base block and configured to receive heat from the heat source, and a thermoelectric cooler including a third end and a fourth end, the third end being thermally coupled to the second end. The thermoelectric cooler is configured to receive an electric current, which causes the third end to cool and the fourth end to heat such that the third end conducts heat from the second end. Related apparatus, systems, techniques, and articles are also described.
1 . An apparatus comprising:
a body configured to receive heat from a fluid;
at least one thermoelectric generator (TEG) having a first end and a second end, the first end of the at least one TEG being thermally coupled to the body and configured to receive at least a portion of the heat from the fluid; and
at least one thermoelectric cooler (TEC) having a first end and a second end, the second end of the at least one TEC being thermally coupled to the second end of the at least one TEG, the at least one TEC being configured to receive electric power, which causes the first end of the at least one TEC to heat and the second end of the at least one TEC to cool such that the second end of the at least one TEC extracts heat from the second end of the at least one TEG.
