Abstract

The invention relates to a novel thermoacoustic regenerator device for improving heat recovery and thermoacoustic conversion efficiency of the thermoacoustic regenerator. The thermoacoustic regenerator device includes a plate stack structure and a needle beam structure, wherein the plate stack structure is composed of a pre-stamped thin plate, a sheet needle beam regenerator, and a regenerator sleeve. The type structure is composed of a single sheet of pre-stamped and formed thin plate in a spiral shape. The pre-punched thin plate has a pre-punched circular hole, or a rectangular hole, or a rectangular hole with flanging. The invention makes full use of the principle of thermoacoustic conversion, takes advantage of the efficient thermoacoustic conversion efficiency of the needle beam regenerator, and at the same time avoids the complicated processing technology, high manufacturing and assembly costs, and unstable work of ordinary needle beam regenerators. Insufficient, and the present invention is simple in structure, and processing, installation are all very convenient.

Description

technical field [0001] The present invention relates to a new type of thermoacoustic regenerator, in particular, it relates to a regenerating and thermoacoustic conversion efficiency, which is convenient for processing, installation and debugging, and can be widely used in thermoacoustic heat engines and cryogenic refrigerators. New thermoacoustic regenerator. Background technique [0002] Thermoacoustic refrigeration technology is a completely new type of refrigeration technology, which is a refrigeration technology that utilizes the thermoacoustic effect. The thermoacoustic effect is the mutual transformation between heat and sound. From an acoustic point of view, it is the interaction between the solid medium in the sound field and the oscillating fluid, which makes the heat flow along (or against) the direction of sound propagation within a certain range from the solid boundary, and generates or The phenomenon of absorbing sound power. According to the direction of en...
