Embodiment Construction

[0027] Figure 1-4 Shown is an embodiment of the present invention, the regenerator assembly 2 is installed inside the regenerator cylinder 1, and a cooler 3 is installed at the lower end, which is composed of an outer sleeve 21 and a wire mesh weldment, and the wire mesh weldment is built in Inside the outer sleeve 21. The wire mesh welding part is composed of a wire mesh welding part 1 22 and a wire mesh welding part 23, and may also be composed of a plurality of wire mesh welding parts. The wire mesh component is stacked with multi-layer wire mesh and then sintered by diffusion welding. The wire mesh is generally made of stainless steel, and the wire mesh of 200-250 mesh is mostly used. The larger the mesh number, the denser the heat recovery effect is, but the greater the flow resistance is, so the regenerator needs to be considered comprehensively in the design The type of wire mesh is selected according to the heat recovery capacity and resistance requirements of the c...

Abstract

The invention discloses a heat regenerator assembly of a heat engine. The heat regenerator assembly of the heat engine comprises a wire screen assembly formed by overlaying a multi-layer metal wire screen and an outer sleeve, the wire screen assembly is arranged in the outer sleeve, the wire screen assembly is composed of two or a plurality of wire screen welding parts, the periphery of the wire screen assembly and the outer sleeve are welded into a whole body by adopting a diffusion welding method, the wire screen welding parts are formed by overlaying a plurality of layers of stainless steel screens with 220-250 mesh, and two vertical adjacent wire screens are welded into an integral body by adopting the diffusion welding mode. The heat regenerator assembly of the heat engine has the advantages of being good in usability, convenient to dismantle and replace, high in reliability and suitable for being applied to Stirling engines.

Description

technical field [0001] The invention relates to a heat engine, in particular to a regenerator assembly for a heat engine. Background technique [0002] The heat engine regenerator is a key component of the heat engine circulation system and one of the key components that directly affects the performance of the heat engine. The regenerator is installed between the heater and the cooler, and its function is to store and release heat energy: when the working fluid moves from the heating tube to the cooler, part of the heat energy in the working fluid is absorbed by the regenerator when passing through the regenerator , so that the temperature of the working fluid can drop from the highest temperature of the cycle; and when the working fluid moves from the cooler to the heating tube in the second half of the cycle, and passes through the regenerator again, the regenerator returns the heat energy to the working fluid, so that The working fluid out of the regenerator gets energy ...
