  • Publication number: 20240029940
    Abstract: The present disclosure provides a magnetic element and a manufacturing method thereof. The manufacturing method including steps of: (a) dividing a magnetic core into a first component and a second component, wherein the first and second components have two connecting surfaces on the split section respectively, and the first and second components have an inner and an outer surfaces; (b) disposing a flexible material on the inner surfaces of the first and second components respectively; (c) sleeving a coil on the first and second components; (d) connecting the two connecting surfaces of the first component to the two connecting surfaces of the second component to assemble the first and second components; (e) utilizing a thermal conduction glue to pot the magnetic element; and (f) curing and forming the thermal conduction glue after a curing time.

  • Patent number: 11519641
    Abstract: An ejector-based cryogenic refrigeration system for cold energy recovery includes a first cryogenic refrigeration loop connected by a helium compressor and a cryogenic refrigerator and a second cryogenic refrigeration loop connected by the helium compressor, a regenerator, an ejector, a cold head of the cryogenic refrigerator, an end to be cooled and a pressure regulating valve. The cryogenic refrigerator is separated from the end to be cooled. The cryogenic refrigerator and the cryogenic helium cooling loop share a helium compressor, which improves the utilization efficiency of the device and reduces the cost. The ejector allows a part of fluids to circulate in the cryogenic loop, so as to maintain a required cryogenic condition, recover the pressure of the fluids, reduce the gas flowing though the compressor loop, and thus reduce the power consumption of the compressor.
