Abstract

The invention discloses a heat source working hot air engine, which comprises a gas working mechanism, a gas compression mechanism, a cylinder piston mechanism, an inner combustion chamber, a work substance outlet and a cooler, the gas compression mechanism, the gas working mechanism and the cylinder piston mechanism are sequentially communicated via a communication channel to form a work substance closed loop; the cooler is arranged on the work substance closed loop which takes the work substance of the gas working mechanism as the upstream unit and takes the cylinder piston mechanism as the downstream unit; the inner combustion chamber is arranged in the work substance closed loop which takes the work substance of the gas working mechanism as the upstream unit and takes the cylinder piston mechanism as the downstream unit. The heat source working hot air engine has a simple structure, and is high in efficiency, low in cost and long in service life.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a heat engine. Background technique [0002] Traditional heat engine such as Stirling engine, the pressure of the cold cylinder and the hot cylinder are basically the same, and the compression ratio is very low (the compression ratio of the best Stirling engine in the world is only about 2), which seriously affects the The efficiency of the Stirling engine is not only that, there must be a specific phase difference between the cold cylinder and the hot cylinder, which inevitably affects its range of use. Therefore need to invent a kind of novel heat engine. Contents of the invention [0003] In order to solve the problems existing in the prior art, the technical scheme proposed by the present invention is as follows: [0004] Scheme: 1: A heat source working heat engine, comprising a gas working mechanism, a gas compressing mechanism, a cylinder piston mechanism, an in...
