Embodiment 1

[0023] Such as figure 1 A built-in integrated Stirling refrigerator is shown, including a linear compressor and an expander. The linear compressor is concave, and the expander is embedded in the linear compressor. A gas passage 4 is provided between the linear compressor and the expander. By embedding and installing the expander inside the compressor, the length of the entire Stirling refrigerator can be shortened, and the mass and volume of the Stirling refrigerator can be reduced.

[0024] Such as figure 2 As shown, the linear compressor includes a moving cylinder 5, a static piston 6 and a linear motor 16, the moving cylinder 5 is driven by the linear motor 16 to reciprocate along its axial direction, and the static piston 6 remains stationary . Specifically, the static piston 6 is sleeved in the dynamic cylinder 5, and the static piston 6 and the dynamic cylinder 5 are in clearance fit. The sealed chamber formed by the static piston 6 and the moving cylinder 5 is the...

Embodiment 2

[0029] Such as Figure 5 As shown, the linear motor 16 is a moving coil linear motor, wherein the mover assembly 9 includes a mover skeleton and a mover coil 20 ; the stator assembly includes a stator skeleton and a stator permanent magnet 19 .

[0030] Others are with embodiment 1.

[0031] Concrete work process of the present invention is:

[0032]First, under the drive of the moving subassembly 9 of the linear motor 16, the moving cylinder 5 reciprocates along its axial direction, and the static piston 6 remains stationary, so that the volume of the compression chamber 3 between the moving cylinder 5 and the static piston 6 change. Secondly, because the compression chamber 3 communicates with the gas passage 4 on the static piston 6 , the gas in the compression chamber 3 enters the gas passage 4 under the action of the reciprocating motion of the moving cylinder 5 . Again, because the gas channel of the static piston 6 communicates with the thermal cavity 14 at the hot e...

Abstract

The invention relates to an embedded integral type Stirling cryocooler, comprising a linear compressor and an expander, wherein the linear compressor is dished, and the expander is embedded and mounted in the linear compressor; the linear compressor comprises a moving cylinder, a static piston and a linear motor, the moving cylinder reciprocates along the axial direction under the driving of the linear motor, and the static piston keeps static; the expander comprises a cold finger, a heat regenerator and a phase adjusting structure for adjusting the movement phases of the heat regenerator and the moving cylinder; a gas channel is formed between the linear compressor and the expander and is formed in the static piston. According to the technical scheme, the embedded integral type Stirling cryocooler is compact in structure, small in size, light in weight, and suitable for environments with strict requirements on the size and the weight of Stirling cryocoolers; the Stirling cryocooler has the characteristics of fewer components, convenience for installing, fixed process, productization and the like.

Description

technical field [0001] The invention relates to the technical field of Stirling refrigerators, in particular to an embedded integral Stirling refrigerator. [0002] Background technique [0003] At present, there are mainly three types of Stirling refrigerators: rotary integral Stirling refrigerators, linear split Stirling refrigerators and linear integral Stirling refrigerators. The rotating integral Stirling refrigerator is driven by a rotating motor and has an "L" shape. Under the rotating condition, not only does it need to increase the counterweight, but the rotating motor will also bring greater radial vibration to the cold head. The linear split Stirling refrigerator is composed of an opposed linear compressor and an expander, connected by branch pipes in the middle, and its shape is "丩" shape. In the linear split Stirling refrigerator, the compressor and the expander need to be placed separately under the rotating condition, which will take up a large space, and th...
