Title:
SMALL TEMPERATURE-DIFFERENCE HEAT ENGINE
Document Type and Number:
WIPO Patent Application WO/2019/200627
Kind Code:
A1
Abstract:
A small temperature-difference heat engine, which is characterized in comprising: an open machine housing (3), the machine housing (3) being provided with a hollow inner cavity; a rotating pair assembly, comprising a rotating wheel (1) that is partly accommodated in the inner cavity, a rotation shaft (2) that is provided on the rotating wheel (1) and that is coaxial with the rotating wheel (1), and a bearing seat (4) that is provided on a wall surface of a radial surface of the inner cavity which corresponds to the rotating wheel (1) and that is suitable for the rotation shaft (2) to be inserted into; and a push-pull assembly, comprising a fixed shaft (5) that is fixedly provided on another wall surface of the radial surface of the inner cavity which corresponds to the rotating wheel (1), a plurality of push-pull units being rotatingly sleeved on the fixed shaft (5) and being distributed in a circumferential array along the rotating wheel (1); the push-pull units comprise a connection rod (8) that is rotatingly sleeved on the fixed shaft (5), an expansion piece (7) that is connected to the connection rod (8), and a supporting seat (6) that is connected to the expansion piece (7); the supporting seats (6) are hinged with a circumferential edge of the rotating wheel (1) by means of hinge shafts (9); the expansion pieces (7) are sealed tank bodies made from an elastic material, and a medium suitable for thermal expansion and cold contraction is sealed within the tank bodies. The engine generates slight expansion or contraction by using the thermal expansion and cold contraction of the medium, thereby outputting power for the rotation of the rotating wheel, being easy to use, having low manufacturing costs, and having a broad range of application.
