Abstract : The present invention relates generally to an improved finned tube heat exchanger, and more specifically to a finned tube support member and a radial bumper support means for reducing heat exchanger damage, efficiency loss, and failure due to vibration and shock loading. In recent years there has been substantial interest in developing superconductive propulsion systems for marine vehicles. Modern marine vehicles have critical component restrictions. Size, weight and complexity are important considerations. A superconducting propulsion system is highly desirable because it is compact and light weight as compared to a comparable, traditional motor-generator system. Superconducting propulsion systems incorporate helium liquefiers which operate at cryogenic temperatures and require a high efficiency heat exchanger. The magnet is a superconducting system must be cooled to an operating temperature approaching 0 degrees Kelvin. The system as a whole operates in normal room temperature. The helium liquefier therefore requires a heat exchanger which is highly efficient throughout a range from about 300 degrees Kelvin to about 4 degrees Kelvin. Patents. (aw)
