Problems solved by technology

[0002] As we all know, the regenerator of a traditional heat engine is generally made of sintered wire mesh weaving. On the one hand, due to the labyrinth flow channel formed by the irregularity of the wire mesh weaving, the working fluid The flow resistance in the regenerator increases, on the other hand, the structural limitation makes the production cost high

Embodiment Construction

[0012] The scroll disc regenerator of the heat generator according to the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] As shown in the figure, the scroll-disk regenerator for a heat engine of the present invention includes a shell 1, two end covers 2 are installed on both sides of the shell, and a central pin 3 is installed between the two end covers 2, Said central pin 3 is fixedly installed in the middle of the two end caps 2, and a scroll 4 wound on the central pin is arranged inside the tubular shell 1, and said scroll 4 is a component tightly arranged in the tubular shell. The scroll coil heat exchange coil, that is to say, the scroll 4 is formed by the heat exchange coil and is sealed in the shell 1 by two end caps 2 and the scroll coil heat exchange coil is pressed tightly In the tube shell, the end face of the coil cannot be axially moved under the impact of the high-pressur...

Abstract

The invention discloses heat regenerators of Stirling engines and particularly relates to a scroll plate type heat regenerator of a Stirling engine. The scroll plate type heat regenerator of the Stirling engine comprises a pipe shell and two end covers which are installed on the two side faces of the pipe shell. A scroll plate which is sealed through the end covers and formed by winding a heat exchange coiled material is arranged in the pipe shell. Through holes are formed in the two end covers correspondingly. By the adoption of the structure, through the arrangement of the scroll plate installed in the pipe shell and the end covers located on the two side faces of the pipe shell and provided with the through holes, working media can successfully penetrate into gaps of the scroll plate from the through hole in one side and flow out of the through hole in the other side, and thus the flow resistance is greatly reduced; and in addition, through the simple structural design of the scroll plate type heat regenerator, the manufacturing cost is greatly reduced.

Description

technical field [0001] The invention relates to a regenerator of a heat engine, in particular to a scroll regenerator of a heat engine. Background technique [0002] As we all know, the regenerator of a traditional heat engine is generally made of sintered wire mesh weaving. On the one hand, due to the labyrinth flow channel formed by the irregularity of the wire mesh weaving, the working fluid The flow resistance in the regenerator increases, and on the other hand, the structural limitation makes the production cost high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a scroll disc regenerator for a heat engine with simple structure, small flow resistance and low manufacturing cost. [0004] In order to solve the above-mentioned technical problems, the scroll regenerator of the heat engine of the present invention includes a tube shell and two end covers installed on both sides of the tube shell. The scroll f...
