Problems solved by technology

[0005] In this way, in the above-mentioned type of rotary Stirling engine, components with poor mechanical efficiency such as power pistons and flywheels can be omitted, so it is desired to realize a Stirling cycle with very high thermal efficiency, but on the other hand, in this type of engine In , there is a problem that a large temperature difference is required in order to utilize the volume change of the gas

Embodiment 1

[0027] figure 1 It is a view schematically showing the configuration of main parts of an embodiment of the rotary heat engine according to the present invention, which will be described below with reference to the accompanying drawings. The rotary heat engine of Embodiment 1 has a substantially triangular rotor 4 rotatably provided inside a cylinder, and a heat receiving part 1 and a heat releasing part 2 are mounted integrally or in contact with the outer periphery of the cylinder 5 . Furthermore, in order to thermally insulate between the heat receiving part 1 and the heat releasing part 2, a heat insulating material 8 is sandwiched between the cylinder walls on the heat receiving part side and the heat releasing part side, thereby forming the cylinder wall in the middle part. In addition, in this embodiment, although a substantially triangular rotor is used, as long as it is an example rotor that can ensure a space for storing vaporized gas, it is not particularly limited t...

Embodiment 2

[0033] figure 2 is a side view of Embodiment 2, which shows the outline of combining an external generator with the heat engine of Embodiment 1. The following description will also be made with reference to the drawings. figure 2 The symbols 4, 5, 7 and figure 1 Similarly, the rotor, cylinder and working fluid reservoir are shown respectively. Also, 9 shows a permanent magnet installed on the rotating shaft 3 of the rotor, which is magnetically connected with a permanent magnet 10 installed on the input shaft of the generator 11 and can rotate with each other without contact. For this reason, by sealing the permanent magnet 9 attached to the rotating shaft 3 of the rotor in the casing provided on the cylinder 5, leakage of the working fluid and / or gas from the cylinder 5 can be completely prevented. In addition, the connection between the rotating shaft of the rotor and an external device such as a generator is not limited to the non-contact connection using magnetic forc...

Embodiment 3

[0036] like image 3 The shown embodiment 3 is the power generation system of the rotary heat engine of the present invention, which is equipped with a capillary tube 16 arranged in the vaporized gas supply circuit 17 connecting the heat receiving part 1 and the working fluid storage part 7, and connecting the heat releasing part 2 The inner wall surface of the cylinder 5 is equipped with fins 15 for heat exchange extending approximately perpendicularly from the inner wall surface of the cylinder toward the rotating shaft 3 of the rotor to improve the output of the rotary heat engine; The polarities of the adjacent magnets are S poles and N poles arranged alternately to arrange permanent magnets 12, 13 with different polarities, and the magnetic force of the permanent magnets 12, 13 is outside the rotation area of ​​the rotor 4. A structure in which the coil 14 for generating electricity is arranged in the area and can generate electricity by itself. In addition, although fin...

Abstract

A rotary heat engine having a cylinder and a rotor having a rotating shaft rotatably placed in the cylinder. The cylinder has a heat receiving section for supplying heat to the inside of the cylinder and a heat radiating section for radiating heat from the inside. The engine also has an engine section body and an operation liquid storage section. A vaporized gas supply channel and a gas recovery channel communicating with the inside of the cylinder are provided, respectively, on the heat receiving section side and heat radiating section side of the cylinder in the engine section body. The operation liquid storage section is between the vaporized gas supply channel and the gas collection channel in order to aggregate and liquefy recovered gas and is installed such that both channels fluidly communicate with each other. Also, the operation liquid storage section has a heat insulation dam provided with a through hole for preventing backflow of fluid flowing inside.

Description

technical field [0001] The present invention relates to thermal power engines, and more particularly to rotary heat engines utilizing external temperature differences. Background technique [0002] Theoretically, the Stirling engine is well known as a heat engine that has very high thermal efficiency and is also environmentally friendly. This Stirling engine generally has a structure of reciprocatingly driving a power piston called a displacer, but in recent years, improved Stirling engines such as a Stirling engine utilizing a diaphragm structure have also been studied. [0003] However, these Stirling engines require a displacer for reciprocating motion, and in order to continue continuous smooth rotation, it is necessary to provide a flywheel for imparting inertia, etc., and there are many disadvantages in terms of mechanical efficiency. [0004] Furthermore, in the improved Stirling engine, as described in JP-A-2003-83166, a disc-shaped displacer has been developed, and...
