Abstract
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.
Claims20
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.
An apparatus comprising:
- first, second, and third thermally conductive members;
- a first thermoelectric cooler (TEC) positioned between, and coupled to, the first and second thermally conductive members, the first TEC being configured to remove heat from the first thermally conductive member, and to deliver heat to the second thermally conductive member;
- a second TEC positioned between, and coupled to, the second and third thermally conductive members, the second TEC being configured to remove heat from the third thermally conductive member, and to deliver heat to the second thermally conductive member;
- a first body having a first passage extending therethrough, the first passage being configured to receive a fluid, and the first body being configured to receive heat from the fluid
- a second body having a second passage extending therethrough, the second passage being configured to receive the fluid from the first passage, and the body being configured to receive heat from the fluid;
- a first thermoelectric generator (TEG) positioned between the first thermally conductive member and the first body, the first TEG being configured to receive heat transferred to the first body from the fluid;
- and
- a second TEG positioned between the third thermally conductive member and the second body, the second TEG being configured to receive heat transferred to the second body from the fluid.
A system comprising:
- a condenser having,
- 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 being thermally coupled to the body and configured to receive at least a portion of the heat from the fluid thereby causing the at least one TEG to generate a first electric power;
- 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 a second 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.
A method comprising:
- delivering a fluid to a body of a heat exchanger;
- transferring heat from the fluid to the body;
- transferring heat from the body to a first end of a thermoelectric generator (TEG);
- delivering a first electric power to a thermoelectric cooler (TEC) thereby causing a first end of the TEC to increase in temperature and a second end of the TEC to decrease in temperature;
- transferring heat from a second end of the TEG to the second end of the TEC;
- and
- creating a temperature gradient across semiconductors of the TEG, thereby causing the TEG to generate a second electric power.
