REFRIGERATOR, AND METHOD FOR PRODUCING VERY LOW TEMPERATURE COLD |
摘要 |
<p>The invention relates to a method for producing very low temperature cold through a dilution cycle wherein a two-phase mixture of the two isotopes 3He and 4He is created in a mixing chamber (2) from liquid 3He and 4He added separately, wherein said mixture of the 3He from a so-called concentrated phase is extracted so as to pass 3He into a so-called diluted phase, and due to which the frigories generated by passing the 3He into the diluted phase are recovered, the phase separation of the two-phase mixture being carried out by monitoring the flows of pure 3He and 4He, added separately into the mixing chamber (2), and by gravity-independent capillary forces, the dilution cycle operating in a closed loop, the method including a first step of recovering and separating the two isotopes 3He and 4He from the fraction of the mixture extracted through a discharge duct (8) and a second step of adding the two isotopes 3He and 4He, separated during the first step, back into the mixing chamber (2). The invention also relates to a refrigerator.</p> |
