Patent ID: 8191380

Claim:
A portable active cryo container, comprising: a protective exterior shell, for enclosing and protecting contents and components of said cryo container; an insulative liner section internal to said protective exterior shell, wherein said insulative liner section is configured to impede the transfer of thermal energy; a plurality of material storage sections defined by said insulative section and by divider walls, wherein each of said plurality of material storage sections are configured to contain storage material and maintain said storage material at a user defined temperature, with each section being configured to maintain a temperature independent of the other sections; at least one bunker section defined by said insulative liner section, wherein said at least one bunker section is configured to contain a volume of solid dry ice; at least one circulating fan driven by an insulated low temperature motor, wherein said fan is configured to push air from said material storage section to said bunker section in a manner that would allow a resultant flow of cool air from said bunker section to said material storage section to maintain a predetermined temperature level in said material storage section; a plurality of air ducts configured to allow air within said at least one material storage section and said at least one bunker section to circulate between said sections as a response to the activation of said at least one circulating fan, wherein the fan is positioned in an air duct that is internal to the insulative liner and wherein the motor is recessed in the insulative liner section outside of the flow of air through the duct; at least one door providing access to said portable active cryo container, wherein said door is insulated; and at least one control system, configured to control the temperature level in said at least one material storage section to a preset level by actively sensing the temperature of said at least one material storage section and responding to fluctuation of said sensed temperature by modulating the activation of said at least one circulating fan.
