Abstract: An improved radiator construction comprising a cooling tube having a barbed end, preferably with an adjacent collar, spaced apart sufficient to engage an elastomeric seal. The seal and tube are positioned in the opening of a radiator or heat exchanger header so that the tube barb and collar and the engaged seal cooperate to retain the cooling tube in the header.

Abstract: A heat exchanger tube having fin elements angled in an acute manner from a lateral axis of the flow tube to promote the deflection of debris. The heat exchanger may have a deflector element positioned between the fin elements to prevent the collection of debris between the fin elements.

Abstract: A heat exchanger is described wherein each heat transfer tube is individually removable along its longitudinal axis such that a dense tube configuration within the heat transfer chamber can be maintained.

Abstract: An improved support for a heat exchanger is disclosed and includes a support member providing four engagement surfaces. The surfaces of adjacent supports, within the heat exchanger, engage so as to provide a force distribution system therein, such that the strength and rigidity of the heat exchanger are enhanced.

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.

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.
