Below, utilize sketch that following each form of implementation is described, Fig. 3 is the diagrammatic sketch after the formation of sterlin refrigerator among Fig. 1 is simplified.
This sterlin refrigerator 100 is the forms of the composition of so-called " 1 discharger+1 piston, heat exchanger loop configurations ".
At first, by electric element 6 turning crankshafts 12, bent axle part 16a, the 16b in the crankshaft room 5 is to differ 90 ° phase rotation.The connecting rod 17a, the 17b that are connected on this bent axle part 16a, the 16b slide free to rotately, make in laterally steering head 18a, 18b cross slide way 19a, the 19b on being located at cylinder 2 that is installed in this connecting rod front end to slidably reciprocate.Utilization is connected compression piston 28 on the connecting rod 17a by compression piston bar 30, when the upper dead center direction moves, be compressed in the working gas in the compression volume 26 in the compression cylinder 24 at compression piston 28, and this working gas is imported in the working space 35 from intercommunicating pore 41.Import the working gas in the working space 35, utilize the downward mobile radiator 45 that is discharged to of gas distribution piston 36, discharge piston 36 and be connected on the connecting rod 17a by discharging piston rod 37.And, be cooled by cool storage container 44 by the working gas of radiator 45 to outside heat release, flow in the expansion space 33 by cooler 43.According to the movement direction of discharging piston 36, working gas only flows at working space 35 and 33 of expansion spaces, and flowing between working space 35 and expansion space 33 can not cause pressure oscillation.That is, single only the generation at discharge piston 36 compressed or expansion.
And when discharging piston 36 in the position that is positioned at 90 ° in the moving process of lower dead centre, when promptly speed was maximum, compression piston 28 reached upper dead center, the speed vanishing.And compression piston 28 when shifting to lower dead centre speed slow down, the volumes in the compression volume 26 increase change little, relative therewith, discharge the speed maximum of piston 36, the volume-variation of working space 35 and expansion space 33 is big, so the working gas in the working space 35 moves in expansion space 33.In addition, in the time of near discharging piston 36 arrival lower dead centres, it is maximum that the volumes in the expansion space 33 also reach.At this moment, compression piston 28 is in the neutral position in the process of lower dead centre motion, and promptly rotational angle is near the position 90 °, and at this moment, it is maximum that speed also reaches.Therefore, the working gass in the compression volume 26 begin to expand, and when the pressure of this working gas reduced, the working gass in the expansion space 33 were transferred in the compression volume 26 in moment, and begin simultaneously to expand and freeze.
Cooled working gas in expansion space 33 dwindles and is discharged to the cooler 43 from expansion space 33 when discharging piston 36 because expansion space 33 when moving to upper dead center; Carry out heat exchange and cool off cooled object at cooler 43 places and outside; And accumulation of heat in cool storage container 44; Then, in radiator 45, carry out heat exchange with media such as ambient atmos or water; Flow into afterwards in the working space 35; Suck the compression volume 26 by intercommunicating pore 41 from this working space 35 at last.Adopt sterlin refrigerator 100 to carry out same circulation repeatedly, can be cooled to-30 ℃～-200 ℃ ultralow temperature state.
In addition, when constituting, compression piston 28 can be constituted as regenerator as heater and with cool storage container 44 as hot room, cooler 43 as power piston, Constant Low Temperature Facilities 34 as stirling engine formula generator.
