Abstract: The present invention relates to an efficient liquefaction system of a regenerative refrigerator using a direct flow, comprising a regenerative refrigeration module and a liquefaction module. The regenerative refrigeration module comprises a regenerative refrigerator unit and a direct flow external circulation unit, wherein the regenerative refrigerator unit comprises, connected in sequence: a compression device, a regenerator hot end heat exchanger, a regenerator, a regenerator cold end heat exchanger, an expansion mechanism cold end heat exchanger, an expansion mechanism and an expansion mechanism hot end heat exchanger. Compared with the prior art, the present invention has smaller resistance to heat exchange, and is especially suitable for a compact GM refrigerator having better refrigeration performance. Because the regenerator is arranged in a cylinder and there must be an air gap between the two, a liquefied working medium flow channel can only be wound outside the cylinder, generating a large air gap thermal resistance to heat exchange of the regenerator; a direct flow led out from the inside is in close contact with a regenerator filler and an alternating flow; and thus almost no heat exchange temperature difference is achieved, and thermal resistance is effectively reduced.
