Description

New-type heat engine

Technical field the utility model relates to a kind of dynamic power machine, be specifically a kind of be the machinery of the energy with the normal temperature air.

The background technique thermodynamic theories is thought: " heat can change merit into, and merit also can change heat into, when a certain amount of heat disappears, certainly leads to the merit of respective amount, and when consuming a certain amount of merit, corresponding with it a certain amount of heat must occur "; " the basic condition that heat energy is converted into mechanical energy is that all have the place of temperature difference can both produce power ... heat energy is converted into mechanical energy continuously needs two thermals source that temperature is different at least ".Current various heat engines all are to do low-temperature heat source with air under the normal temperature or water, must have a high temperature heat source that is higher than ambient temperature that heat energy is provided simultaneously, and the part of the heat energy that is provided is transformed into mechanical energy.As, with water is the steamer of working medium, must there be the high temperature heat source that is higher than ambient temperature that heat energy is provided during its work, this high temperature heat source provides the temperature of heat energy must be greater than 100 ℃ of the normal points of water, that is to say, its necessary condition is: existingly can make liquid water absorb that heat becomes high-pressure and high-temperature steam and the external high temperature heat source of work done, the low-temperature heat source that becomes liquid water after the steam heat release work done is also arranged.

The heat engine of summary of the invention the utility model is with the air under the normal temperature or the water machinery as thermal source, the dual functions with generating and refrigeration.This equipment mainly partly is made up of compressor, No. two compressors, heat exchanger, No. two heat exchangers, throttle valve, steam turbine generator, refrigerator etc., has pipeline to connect therebetween.Heat exchanger, No. two heat exchangers all be one by outer heat insulating tube suit in the device of heat-transfer pipe, steam state or liquid working substance are reverse flow in heat insulating tube and the interior heat-transfer pipe outside.The structure of the utility model has two circulatory systems, i.e. power generation system and refrigeration system, and the boiling point of power generation system working medium is lower than the temperature of ambient air, and the boiling point of refrigeration system working medium is less than or equal to the boiling point of power generation system working medium.The flow process of refrigeration system is: heat-transfer pipe → refrigerator → (compressor) in outer heat insulating tube → throttle valve → No. two heat exchanger of compressor → No. one heat exchanger; The flow process of power generation system is: outer heat insulating tube → No. two compressor of interior heat-transfer pipe → steam turbine generator → No. two heat exchanger of a heat exchanger → (heat-transfer pipe in the heat exchanger).

Compressor communicates with the inlet side of an outer heat insulating tube of heat exchanger and the end that goes out of refrigerator respectively by pipeline, and No. two compressors communicate with the inlet side of heat-transfer pipe and the end that goes out of No. two outer heat insulating tubes of heat exchanger in heat exchanger respectively by pipeline; Communicating with the inlet side that goes out heat-transfer pipe in end and No. two heat exchangers of heat insulating tube outside heat exchanger respectively of throttle valve into and out of two ends; The inlet side that goes out end, No. two outer heat insulating tubes of heat exchanger of an interior heat-transfer pipe of heat exchanger communicates with steam turbine generator respectively.A heat-transfer pipe is arranged in the refrigerator, and the inlet side of this heat-transfer pipe communicates with the end that goes out of No. two interior heat-transfer pipes of heat exchanger, and the end that goes out of this heat-transfer pipe communicates with a compressor.The import and the outlet of air are arranged on the refrigerator.

The utility model can be realized generating simultaneously, two functions of freezing, its principle is: during work, compressor of driven by motor and No. two compressors, No. one compressor makes the working medium (as ammonia) under the normal temperature become high temperature, the high pressure gas enters the outer heat insulating tube of heat exchanger No. one, so the working medium in should outer heat insulating tube has been passed to the working medium in the heat-transfer pipe in heat exchanger with self most of heat, working medium in the outer heat insulating tube of this heat exchanger is by behind the throttle valve, the temperature step-down of working medium, pressure descends---by the steam state liquefy, enter thereupon and pass the interior heat-transfer pipe of heat exchanger No. two, after the working medium of heat-transfer pipe has absorbed the heat of No. two outer heat insulation intraductal working mediums of heat exchanger in these No. two heat exchangers, enter the heat-transfer pipe of refrigerator, just can be with the air cooling that enters in the refrigerator, the air that blows out in the refrigerator becomes cold wind, working medium in this heat-transfer pipe has become steam state by liquid state when refrigerator comes out, turn back to compressor again No. one.Meanwhile, working medium (as: steam state octafluorocyclobutane) in the outer heat insulating tube of No. two heat exchangers, after the part heat being passed to the working medium of interior heat-transfer pipe, temperature reduces, treat that the working medium temperature reduces to boiling point when following, working medium is by the steam state liquefy, through behind No. two compressors, working medium becomes high-pressure liquid by the normal pressure liquid state, then after drawing heat energy the heat insulating tube outside heat exchanger, working medium is become the steam state of High Temperature High Pressure again by liquid phase-change, and the working medium of this High Temperature High Pressure just can drive the steam turbine generator work done, working medium enters the outer heat insulating tube of heat exchanger No. two with the gas state of low-temp low-pressure after the steam turbine generator work done---finish a thermodynamic cycle process.The above, the overall process that the heat that will obtain in the refrigerator is converted into the electric energy of steam turbine generator has been described, because the electric energy that steam turbine generator produces is greater than the summation of No. one, No. two compressor power consumptions, therefore successfully the heat energy of ambient temperature gas has been transformed into mechanical energy.The utility model can not only be with the air under the ambient temperature as the energy, also can be with the water under the ambient temperature as the energy.The utility model has scientifically been realized the conversion of heat energy and kinetic energy, has the important practical meaning of energy saving, raising machine work efficient.
