  • Patent number: 4344478
    Abstract: An improved heat exchange apparatus useful for cooling hot oil generated through the operation of industrial machinery. The improved apparatus has a support member, at least one heat exchange tube secured at each end to the support member, and an elongated heat exchange tube retainer. The central portion of the heat exchange tube has at least one heat exchange fin extending outwardly from the periphery of the tube. The heat exchange tube retainer is mounted on a heat exchange tube end portion to hold the heat exchange tube firmly in place within the support member and preferably, although not necessarily, has at least one protruding portion that deflects air towards the heat exchange fin extending from the heat exchange tube retainer to enhance the heat exchange effectiveness of the apparatus.

  • Patent number: 4216824
    Abstract: The invention relates to spacers for the individual units of a heat exchanger assembly containing a plurality of tubes with cooling fins secured thereto. The specifically shaped, readily removable and usable spacers are positioned in the heat exchanger assembly between fins of adjacent fin and tube assemblies and between fins of each individual fin and tube assembly particularly in situations where the tubes are quite long, i.e., about two feet or more in length. The spacers are formed of blocks of substantially solid somewhat resilient material, preferably an elastomeric heat and fluid resistant material. The spacers may have opposed stop flanges or wings formed thereon to provide a finished product which as a cross or crucifix-type cross section.
