Abstract

1502214 Refrigerating AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE 19 Nov 1976 [19 Nov 1975] 48472/76 Heading F4H An adsorption pump for obtaining temperatures below 1‹ K. utilizing He 3 or He 4 comprises a cryostat 1 housing an enclosure 6 spacedly surrounding a main cell 10 containing a gas adsorbent material 14 and which is connected by a column 4 to a space to be exhausted in a lower chamber 5. The gap 18 between the enclosure and cell contains a selected gas, e.g. helium and is used to conduct heat between the cell 10 and liquified gas 2 in the cryostat or to act as a thermal insulation means by connection to an auxiliary chamber 7 containing gas adsorption material 19, e.g. active carbon and an electrical resistance heater 21 so as to control the pressure within the enclosure. In operation, helium in the gap 18 is adsorbed by the material 19 in the chamber to ensure thermal insulation of the cell, helium gas, He 3 or He 4 is introduced through a capillary tube 9 into the column 4 to liquify in the column by cooling by the liquid bath 2, an electrical heater 15 associated with the cell 10 heating the material 14 to prevent absorption and the liquid so produced being collected in the chamber 5 as a bath 23. Thereafter, closure of the capillary tube 9, shut-down of the heater 15 and operation of the heater 21 desorbs helium from the material 19 and ensures thermal conduction across the gap 18 to allow the material 14 to adsorb helium in the column 4 with a consequential pressure drop, evaporation of the bath 23 and fall in temperature. In a modification, two cells are arranged side-by-side, each having its own auxiliary cell and connected to a single column through respective ball valves coupled to double bellows to achieve continuity of operation.
