A Stirling engine device

Abstract

The present invention relates to the technical field of engines, in particular to a Stirling engine device. The Stirling engine arrangement includes: an active cylinder, a passive cylinder and a heater. The Stirling engine device proposed by the present invention adopts a double-cylinder action mode. The heater heats the gas in the hot cavity of the active cylinder, and the cold gas in the cold cavity flows into the hot cavity, which pushes the first piston to move toward the first runner, and drives the The first runner rotates; the gas in the cold cavity enters the intake cavity of the passive cylinder, pushes the second piston to move toward the second runner, and drives the second runner to rotate until the second piston reaches the left dead center. Due to the inertia of the components such as the first and second runners and the rotating shaft, they continue to rotate, the first piston and the second piston move in the opposite direction, the active cylinder inhales the outside air through the first intake valve, and the passive cylinder discharges the air through the air outlet. Complete a work cycle. There is always a temperature difference between the cold and hot chambers of the active cylinder, allowing the Stirling engine unit to operate continuously.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a Stirling engine device. Background technique [0002] The Stirling engine outputs power through a cycle of cooling, compressing, absorbing heat, and expanding the working medium (hydrogen or helium) in the cylinder, so it is also called a heat engine. The Stirling engine is an external combustion engine, and its effective efficiency is generally between gasoline engines and diesel engines. At home and abroad, the Stirling engine has been maturely used in submarines, and has not been widely used in civilian vehicles like internal combustion engines. Abroad, a small number of countries such as the United States, Brazil and the United Kingdom have begun to produce a small amount of Stirling ethanol engines for use in automobiles, but the power is still low. [0003] At present, in China, the Stirling ethanol engine is in the development and trial stage. The circulation of the c...

Problems solved by technology

This circulation method has the following problems: when the room temperature is less than 22°C, the Stirling engine can run for a long time; ) the temperature difference is very small, the Stirling engine will stop running, so it cannot run continuously in summer, resulting in low output power of the Stirling engine, which limits its operation and promotion

[0004] In order to generate a temperature difference between the gas before and after the active cylinder piston, the technical solution of the Chinese patent CN101280737A consists of a plurality of heating tubes to form a heater tube group to enhance heating, and a cooling tube group to enhance cooling, which is easy to cause damage to the heater and cooler and the structure is complicated. The flow resistance of gas in the heater and cold chamber is large, and the actual operating efficiency is low
