HEAT EXCHANGER FOR SUPERFLUID HELIUM GENERATION

PURPOSE:To keep a sufficient performance of heat-exchanging with helium to certainly generate superfluid helium even under cryogenic temperatures at which Kapitza resistance increases remarkably. CONSTITUTION:Fins 22 and 24 are attached on the surfaces of main bodies 14, 16 and 18 made of copper. Or...

Summary:PURPOSE:To keep a sufficient performance of heat-exchanging with helium to certainly generate superfluid helium even under cryogenic temperatures at which Kapitza resistance increases remarkably. CONSTITUTION:Fins 22 and 24 are attached on the surfaces of main bodies 14, 16 and 18 made of copper. Or, particles composed of metals such as copper, etc., are sintered on the surface and a lead-tin alloy thin layer or metallic oxide layer is formed on the surface of the particles.
