Hot working medium generator

Abstract

The invention discloses a hot working medium generator. The hot working medium generator comprises a pressure vessel, wherein a heating area and a cooling area are arranged in the pressure vessel, the heating area is heated through a heat source, the heating area and the cooling area are filled with liquid, the cooling area is connected with a cooling device, a steam turbine is installed in the cooling area, the heating area is provided with a steam nozzle, the steam nozzle is communicated with a steam inlet of the steam turbine, and the steam turbine is connected with a generator body. The hot working medium generator further comprises a water pump, wherein a water inlet of the water pump is communicated with the cooling area, and a water outlet of the water pump is communicated with the heating area. According to the hot working medium generator, the power generation noise is small, no obvious mechanical vibration exists, and the power generation effect is obviously better than that of internal combustion engine power generation; the interior of the pressure vessel is closed, and normal working can be realized in an air-free environment; the structure is simple and small and is smaller than the structure of an internal combustion engine power generation system and a semiconductor thermoelectric power generation system under the same power condition; and the hot working medium generator has no requirement for a heat source and can realize power generation only through a working medium capable of generating high temperature.

Description

technical field [0001] The invention relates to a generator, in particular to a thermal working medium generator. Background technique [0002] At present, the common products that use thermal fluid to generate electricity mainly include internal combustion engine systems, external combustion engine systems and thermoelectric power generation systems. [0003] Among them, the structure of the internal combustion engine power generation system is basically the same as that of the automobile engine. It mainly uses the gas expansion generated by fuel combustion to drive the piston to do work, and uses the piston to do work to drive the motor to generate electricity; [0004] The external combustion engine power generation system is mainly a steam turbine power generation system, which uses fuel combustion to heat water, drives the steam turbine through the water vapor pressure, and uses the rotation of the steam turbine blades to do work to drive the motor to generate electrici...

AI Technical Summary

Problems solved by technology

[0008] As far as the above three schemes are concerned, although they can cover high power to micro power, and the devices vary in size, there are still some deficiencies and technical gaps

First of all, due to the low thermal efficiency of semiconductor thermoelectric power generation, it is not suitable for power sources of equipment with medium power and above. Although it can be used in an airless and gravity environment, the cost of isotope thermoelectric generators is too high due to the low power generation efficiency (for example, the use of Perseverance) The output power of the isotope thermoelectric generator is only 110W, and the cost is as high as hundreds of millions of dollars); secondly, the internal combustion engine power generation system can also be small in size and the power meets the demand, but the internal combustion engine power generation system vibrates due to the movement of the piston, and the exhaust emissions cause a lot of noise , there are also relatively large shortcomings; finally, the steam turbine is not suitable for miniaturization, because its structure is too large, so the scope of application is extremely narrow
