  • CRYOGENIC DEVICE WITH COMPACT EXCHANGER
    Publication number: 20190120529
    Abstract: This cold generation device implements the “Joule-Thomson” expansion principle. It includes a heat exchanger having a fluid under high pressure and under low pressure circulating in counterflow therethrough. The heat exchanger is formed of the stack of pellets (5) made of a porous material, and particularly a sintered material, forming a cylindrical mandrel, having a capillary (10) wound at the periphery thereof and in contact therewith, the capillary having the high-pressure fluid circulating therethrough, the low-pressure fluid circulating in counterflow inside of the porous mandrel thus formed.
