Abstract:
A modular cryogenic cooler for removably interfacing with an insulated container, said cooler being configured for maintaining an interior of the container at a super-frozen temperature of less than or equal to about âˆ’45 degrees C., said cryogenic cooler comprising:a modular connector configured for removable engagement with the container; a cryogenic fluid transport module coupled to said modular connector; said transport module having a cryogenic fluid supply coupling; said supply coupling being couplable to a cryogenic fluid source; said transport module being configured to selectively feed cryogenic fluid from the source to the container; a controller operationally coupled to said transport module to maintain the interior of the container at the super-frozen temperature; said controller including a programmable processor having computer readable program code embodied therein, the computer readable program code including instructions for: receiving a temperature reading from a temperature probe; comparing said temperature reading to a preselected temperature; actuating said transport module to selectively feed cryogenic fluid from said source to said container; and wherein said modulator connector comprises a door sized and shaped for sealing engagement with an opening of the container.
