METHOD FOR OBJECT CRYOSTATTING AND DEVICE FOR ITS REALISATION Russian patent published in 2010 - IPC F25B9/14 F28D15/04 

FIELD: machine building.

SUBSTANCE: method for object cryostatting includes charging working medium (WM) into inner cavity of tight pressure shell (TPS) of cryogenic accumulator (CGA), heat removal from WM, displacement of WM part in liquid phase along wick from porous material from zone of heat removal from WM to zone of heat removal from cryostatted object, termination of heat removal from WM, stabilisation of cryostatted object temperature by means of heat removal along pipeline from cryostatted object to WM, and transfer of some WM from solid phase into liquid phase. Wick is installed along inner surface of TPS in direction of longitudinal axis of TPS and operates according to principle of capillary pump. Some WM in liquid phase is moved along additional wicks from porous material in transverse direction from zone of heat removal on pipeline to zone of heat removal from elements of CGA, having temperature above temperature of heat removal zone on pipeline. Pipeline passes along longitudinal axis of CGA. When in process of WM cooling, specified maximum volume of solid phase of WM is achieved, heat removal is terminated along pipeline from WM. When in process of heating, volume of WM solid phase reduces down to specified minimum value, heat is removed along pipeline from WM.

EFFECT: reduced mass and dimensions and increased resource of cooling system operation, reduced range of cryostatted object temperature variations and reduced temperature difference between WM in solid phase and cryostatted object.
