Stirling engine with eccentric shaft rolling rotation ring

Abstract

The invention relates to a Stirling engine with an eccentric shaft rolling rotation ring, the Stirling engine is characterized in that a cylindrical air cylinder is divided four spaces, namely two inner space and two outer through the eccentric shaft rotation ring, an inner slip sheet and an outer slip sheet, the volumes of the inner spaces and the volumes of the outer spaces periodically change, the outer paces are cold cavities, an outer shell is a radiator, the inner spaces are hot cavities, simultaneously, a heater is arranged in an inner shell, a working medium gas is high-pressure carbon dioxide, heat expansion and cold contraction of the working medium gas are respectively and simultaneously carried out in the hot cavities and the cold cavities which have periodically-changed volumes, the working medium gas is heated in the heater in the inner shell, and sequentially is subject to inflation in the hot cavity C, deflation in the hot cavity D, inflation in the cold cavity B, and deflation in the cold cavity A, and due to the pressure difference between the hot cavity C and the hot cavity D and the pressure difference between the cold cavity A and the cold cavity B, the eccentric shaft rotation ring is driven to clockwise rotate to work. Thus, in the Stirling engine, the system has a simple and compact structure; as the heat expansion and the cold contraction of the working medium gas are simultaneously carried out, and the working medium gas always flows towards the same direction, the engine has good movement stability without pulsation; compared with a piston type external combustion engine, the system heat efficiency is improved; the working medium gas adopts the high-pressure carbon dioxide which has good flowability and can absorb heat in a subcritical zone and discharge heat in a supercritical zone, so that the working medium gas has a good heat-transfer characteristic, the cost is low, and the environmental-friendly effect is achieved.

Description

technical field [0001] The invention relates to a Stirling engine device with an eccentric shaft rolling swivel, which is characterized in that: the cold chamber of the engine is arranged outside, and the hot chamber is arranged inside, and the working medium gas is respectively in the hot chamber and the cold chamber whose volume changes periodically. thermal expansion and cold contraction. Background technique [0002] At present, due to the wider adaptability of external combustion engines to fuels than traditional internal combustion engines, and the characteristics of external combustion engines with simple structure and few parts, external combustion engines have a wide range of applications in cogeneration of heat and power, waste heat recovery and utilization, and specific application environments. the use of.

Problems solved by technology

At present, external combustion engines mainly use traditional piston cylinders as the main components, and mechanical connecting rods are required to convert the linear motion of the piston into circular motion, which makes the system bulky and heavy, which affects the market application and promotion of external combustion engines.
