Problems solved by technology

This invention uses the high pressure of the gas working medium to absorb heat and expand to drive the gas turbine to rotate, and uses the air compressor to circulate the working medium, without gas-liquid phase change, and the heat exchange chamber is not used to dissipate heat from the outside, so it is difficult to have a cooling and heat dissipation effect, which is equivalent to using an air compressor to drive Steam turbine, less practical

Abstract

The invention relates to an external combustion engine, in particular to a rotary external-combustion engine and a rotary external-combustion generator. The invention is characterized in that a working medium is heated to convectively circulate and generate power to drive rotation, and the circulation can be closed circulation. The rotary external-combustion generator utilizes heat absorbed by a heat pump as a heater to lead the working medium to be heated to convectively circulate and generate power to drive rotation and generate power. The thermodynamic cycle is mainly finished by heating and working of the heater, so that the heat loss in cooling and heat releasing can be reduced or avoided. In the invention, the structure is simple, the pollution is less, the efficiency can be obviously improved, the use of circulatory cooling water in a heat power plant can be greatly reduced, and the earth can be properly cooled if the surface water, the underground water, the rivers, the lakes, the seas, the air and the like are used as external heat sources.

Description

1. Technical field: [0001] The invention relates to an external combustion engine, in particular to a rotary external combustion engine and a rotary external combustion generator, which use working medium to be heated and convected to generate power to drive rotation and work. Can be closed loop. The thermal cycle is mainly completed by heater heating and workmanship, which can reduce or avoid heat loss due to cooling and heat release. The structure is simple, the pollution is small, the efficiency can be significantly improved, and the use of circulating cooling water in thermal power plants can be greatly reduced or avoided. If rivers, lakes, seas, air, etc. are used as external heat sources, the earth can be cooled. Rotary external combustion engines can also be used in air conditioners. 2. Background technology: [0002] We know that energy consumption and resource reduction make human beings need more efficient heat engines. Steam engines, steam turbines (revolving he...
