Technical Field
The invention relates to a power generation device, in particular to a jet power generation device and a jet power generation method.
Technical Field
With the increasing severity of energy and environmental pollution, thermoelectric materials attract extensive attention because of their advantages of no pollution, no noise, small volume, long service life, and being capable of being accurately controlled. Thermoelectric materials have irreplaceable advantages in terms of power generation, environmental protection, no vibration, no noise, miniaturization, easy control, reliability, long life, and the like.
Thermoelectric devices operate based on the internal effects of thermoelectric materials, allowing for energy conversion. The Seebeck effect of the thermoelectric material, also called thermoelectric generation effect, means that in a loop formed by two different conductors, if the temperatures of two end faces of the conductors are different, electromotive force is generated in the loop, and when a load resistor is added, direct current is generated.
Thermoelectric power generation is a novel power generation mode, and heat energy is directly converted into electric energy by utilizing the Seebeck effect. The semiconductor temperature difference generator manufactured by the semiconductor temperature difference generating module can generate electricity as long as the temperature difference exists.
As known from the literature, the thermoelectric performance of the material is determined by nondimensional thermoelectric figure of merit ZT, ZT = S 2 Sigma T/K, wherein S is a Seebeck coefficient; σ is the electrical conductivity, T is the temperature difference, and κ is the thermal conductivity. The larger the thermoelectric figure of merit, the higher the thermoelectric conversion efficiency. The Seebeck coefficient S of the semiconductor material is increased by applying pressure on the semiconductor material, so that the thermoelectric figure of merit is increased, and the power generation capacity is improved. The invention is different from the principle that the power generation capacity is improved by applying pressure to a semiconductor material to reduce the contact thermal resistance in the literature; and is different from the method of pressing the semiconductor material by using a diamond anvil in the literature.
