Definitions

  • the invention relates to a device for transporting thermal energy at temperatures lying below the lt-temperature of helium between a cooled He container having a temperature lower than that of the )t-point and a place to be cooled or a further container; the device comprises a pipe which has one end in communication with said container and the other end of which can be brought in thermal contact with the object to be cooled or debouches in the further container.
  • the device according to the invention is characterized in that the pipe comprises a sin tered superleak which extends throughout the length of the pipe and covers a part of the cross-section of the pipe.
  • a superleak is to be understood to mean a mass of material of such a high density that normal fluid cannot pass through said mass and superfluid can pass through said mass without turbulence in the fluid.
  • the superleak covers the whole inner wall of the pipe.
  • the advantage of this is that the superleak also counteracts penetration of thermal energy from without.
  • Reference numeral 1 denotes a container filled with liquid He at a temperature lower than that of the A-point.
  • pipe 2 communicates with the said container and communicates at its other end 3 in a heat conducting manner with an object 4 to be cooled.
  • the inner wall of the pipe 2 is covered with a superleak 5 of, for example, sintered aluminum oxide particles or silicon carbide particles.
  • a superleak has the property that normal fluid cannot pass through it, while superfluid flows through such a superleak without turbulence occurring.
  • the superfluid will start flowing to the end 3 of the pipe while an equally large mass flow of normal fluid will flow to container l.
  • the superfluid will flow through the superleak 5 without turbulence, so that the flow of normal fluid is not impeded. In this manner, a particularly large amount of thermal energy can be transported through pipe 2, with a small temperature difference across the pipe.
  • the superleak against the inner wall of the tube 2 has the advantage that the superleak. counteracts inleak of thermal energy but, if desirable, the superleak may also be arranged detached from the wall of the pipe.
  • the pipe may also be made to communicate with a further container which, for example, serves as a storage container from which liquid can be drained or which is in thermal contact with a number of objects to be cooled.
