Problems solved by technology

[0002] The gas-moving piston of the traditional heat engine continuously moves the working gas back and forth between the heating chamber and the cooling chamber. An external regenerator is required to connect the heating chamber and the cooling chamber to absorb and dissipate the residual heat energy of the work. The working gas is heated The cavity expands, pushing the power piston to do work, and at the same time, it also produces an impact force on the statically installed regenerator, which makes this part of energy wasted. In addition, the manufacturing process and cost of the external regenerator are relatively high

Abstract

The invention discloses an improvement of Stirling engines, and particularly relates to a hot-air engine with an air moving piston internally provided with a regenerator. The hot-air engine comprises an expansion chamber with a heater and a compression chamber with a cooler, the expansion chamber is communicated with the compression chamber, and the air moving piston for separating the two chambers is arranged between the expansion chamber and the compression chamber and is internally provided with the regenerator. After the structure is adopted, the regenerator is arranged in the air moving piston, working medium air expands in the heating chamber and generates no impact force on the regenerator in the process of pushing the power piston to do work, enough energy is ensured, heating energy is used fully, and therefore efficiency of the hot-air engine is improved. In addition, the hot-air engine is compact in structural design and simple in manufacturing process, and cost is reduced.

Description

technical field [0001] The invention relates to an improvement of a Stirling engine, in particular to a heat engine with a built-in regenerator and gas-moving piston. Background technique [0002] The gas-moving piston of the traditional heat engine continuously moves the working gas back and forth between the heating chamber and the cooling chamber. An external regenerator is required to connect the heating chamber and the cooling chamber to absorb and dissipate the residual heat energy of the work. The working gas is heated The cavity expands, pushing the power piston to do work, and at the same time, it also produces an impact force on the statically installed regenerator, which makes this part of energy wasted. In addition, the manufacturing process and cost of the external regenerator are relatively high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a heat engine with a built-in regenerator and gas-moving...
