Abstract
An integrated Stirling refrigerator is composed of two parts: a compressor and an expander. The compressor is composed of a shell (), a piston (), a leaf spring (), a magnet (), a coil (), a bracket () and a support shelf (). The shell () of the compressor includes two cylinders (), one of which is set inside the other to form a compression chamber (). The piston () is connected with the leaf spring (). The coil () is fixed between the inside of the shell () and the bracket (), and the magnet () is fixed between the bracket () and the support shelf (), wherein the bracket () and the support shelf () are respectively connected with the shell (). The inside of the expander is divided into two chambers by a small piston and a regenerator () fixed together, that is, an expansion chamber () and a pneumatic chamber, and a cylindrical spring () is provided on the bottom of the expander. The center of the compressor is designed as a groove, and the expander is inserted into the groove of the compressor. There is a small hole designed on the bottom of the expander, which is communicated with the compression chamber () of the compressor. The Stirling refrigerator has the advantages of compact structure and small volume, and hence it can be widely used.
