Closed cold and heat cycle engine

Abstract

The invention discloses a closed cold and heat cycle engine, which comprises two sealed cycle pipelines and one sealed cavity, wherein working medium gas is filled in the two sealed cycle pipelines, a front piston cylinder and a back piston cylinder are arranged on the sealed cavity, the two sealed cycle pipelines are respectively connected onto the front piston cylinder and the back piston cylinder, a rotating shaft is arranged in the sealed cavity, one end of the rotating shaft is connected with a flywheel, a front crack and a back crank with a phase angle being 180 degrees are respectively connected onto the rotating shaft, the front crank is connected with a piston arranged in the piston cylinder, the back crank is connected with a piston arranged in the back piston cylinder, a valve A is respectively arranged between the upper part of the heating end and the upper part of the cooling end in the two sealed cycle pipelines, and a valve B and a valve C which are positioned at the two sides of the connecting pipeline are respectively arranged between the lower part of the heating end and the lower part of the cooling end in the two sealed cycle pipelines. The closed cold and heat cycle engine has the advantages that the structure is simple, the energy source consumption is less, and the motive power conversion efficiency is very high.

Description

[0001] technical field [0002] The invention relates to a cycle engine device, in particular to a closed cold and heat cycle engine. Background technique [0003] There are many types of existing engines, including fuel engines, electric motors, and Stirling engines, etc., especially Stirling engines that use a variety of fuels as energy sources, which are of great significance in solving energy shortages and reducing environmental pollution. ; However, due to its complex structure, the energy consumption is still relatively large, and the efficiency is not very high, which still restricts people from widely using it. Contents of the invention [0004] The technical problem to be solved by the invention is to provide a closed cooling and heating cycle engine with low energy consumption and high efficiency. [0005] In order to solve the above-mentioned technical problems, the closed cooling and heating cycle engine of the present invention includes two closed circula...
