Stirling Cycle Device

摘要

A Stirling cycle device includes a housing with an inner wall, and a regenerator attached to the inner wall of the housing, wherein the regenerator, made of wool or chemical fiber, is composed of two, three, or four sub-regenerators and the height of the regenerator is independent on number of sub-regenerators. As the regenerator is made of wool or chemical fiber, which may ensure a sufficient permeability and heat storage performance; as the regenerator is composed of a plurality of sub-regenerators, clearances may be formed between each two sub-regenerators, and as the clearances have a density less than the surrounding sub-regenerators, these clearances may be used for energy storage, heat insulation and air circulation. Consequently, the refrigerating performance of the cycle device is improved as the efficiency of pre-cooling and pre-heating of the working gas in the regenerator is improved.
