- The present invention relates to a Stirling cycle device for cooling or heating or the like.
- A Stirling cycle device is a device in which a displacer and a piston are coaxially provided inside an air cylinder so that when in operation, the reciprocating motion of the piston drives the gas to expand or compress periodically in order to generate cold (or heat). A compression chamber is formed between one end of the displacer and the piston while an expansion chamber is formed at the other end of the displacer, a regenerator is disposed between the compression chamber and the expansion chamber, and the two chambers are communicated to each other through the regenerator to form a closed loop inside the cycle device. Heat absorbers (at the end where the expansion chamber is formed) and heat sinks (at the end where the compression chamber is formed) are provided at two ends of the regenerator, each heat sink having cooling fins which facilitate heat exchange with the outside air. The piston is driven to allow the gas inside the compressed chamber to be compressed and fed into the regenerator and further conveyed into the expansion chamber, with heat of the gas being accumulated by the regenerator, hereafter, the compressed high-pressure working gas expands inside the expansion chamber. Then, the temperature falls, the piston resets, and the working gas returns back to the compression chamber through the regenerator again. The heat accumulated inside the regenerator is imparted to the working gas so that the temperature of the working gas rises. By repeated cycles, the temperature of the heat absorbers gradually becomes low, to be extremely low. The principle of heating is similar.
- In the prior art, the regenerator is usually made of resin. Such a regenerator, however, is complicated in manufacturing, and the refrigerating efficiency is decreased due to the poor permeability, which hinders the circulation of cold air and hot air in some extent, of the resin. For this reason, regenerators made of other materials have been disclosed in the prior art. For example, a Stirling refrigerator disclosed in a Chinese Patent Application, the application No. 00817515.2, the regenerator is a matrix of fine wire or a ring-shaped gap formed by wounding foil. However, due to the large coefficient of heat conductivity, quick heat radiation and poor energy storage performance of the wire, both the pre-cooling of hot air when it passes through the regenerator and the pre-heating of cold air when it passes through the regenerator are insufficient. As a result, the refrigerating efficiency is also decreased.

However, the existing cooling fins, for example, those used in a heat exchanger for a Stirling refrigerator as disclosed in a Chinese Patent Application (Application No. 01815042.X), are integrally formed an annular corrugated fin that is produced by forming a sheet material, corrugated so as to have a large number of grooves, into a cylindrical shape with the grooves parallel to an axis of the cylindrical shape. When it is intended to ensure smooth circulation of gas, the sides of the grooves of the corrugated fin have a small contact area (or even no contact), i.e., large opening of the V-grooves, thereby resulting in low heat conductivity; and when it is intended to improve the heat conductivity, the cooling fins should have a large contact area (i.e., large cooling area), for this purpose, the grooves are squeezed, the V-shape of the grooves is compressed and the opening of the V-shape is reduced (or even closed), consequently, the circulation of gas is hindered. That is, the existing folding manner is unable to ensure both the smooth circulation of gas and the improved heat conductivity, and thus unable to realize high heat exchange efficiency.

- The regenerator has a height between 34.5 mm and 36 mm, a wall thickness between 4.8 mm and 5 mm, and an outer diameter between 36.6 mm and 36.8 mm. The permeability and the heat insulation may be best balanced by controlling the overall weight of the regenerator, and the refrigerating efficiency is thus improved.

- As a preference, the transverse section of the cylinder of each heat dissipation element has a perimeter between 98 mm and 98.5 mm, the annular thickness of the transverse section is between 4.6 mm and 4.7 mm, and the height of the cylinder is between 6.8 mm and 7 mm.
- As a preference, each of the first cooling element and the second cooling element has multiple pores with a porosity between 10% and 90%.
