  • Cryocooler for HTSC filter systems
    Patent number: 6499304
    Abstract: An improved HTSC filter system design. An improved HTSC filter system comprises a cryocooler and dewar assembly, a heat dissipation assembly and at least one heat pipe providing a thermal coupling between said heat dissipation assembly and said cryocooler and dewar assembly. In a preferred embodiment, the cryocooler and dewar assembly is environmentally sealed within a double-walled aluminum canister, and the heat pipes are formed from stainless steel tubes having a predetermined amount of ammonia provided therein.
    Type: Grant
    Filed: November 6, 2001
    Date of Patent: December 31, 2002
    Assignee: Superconductor Technologies, Inc.
    Inventors: David R. Chase, Mark W. Hanes, Wallace Y. Kunimoto, Amr H. O'Baid
  • Cryocooler motor with split return iron
    Patent number: 6427450
    Abstract: A cryocooler having an improved linear motor assembly. The cryocooler comprises a displacer unit, heat exchanger unit and compressor and linear motor assembly. The compressor and linear motor assembly includes a linear motor having both a stationary internal return iron element and a moving internal return iron element, thus enabling the motor to operate at a predetermined resonant frequency. In a preferred form, the compressor and linear motor assembly comprise a unitary structure.
