  • Flow guiding in tube bundle heat exchangers
    Patent number: 4397350
    Abstract: A heat exchanger is disclosed as including a bundle of tubes within a tubular casing, wherein uniform helical flow of a heat exchange medium within the casing is created by a series of stepped transverse baffle plates having the shape of circular sectors. Successive sectors are interconnected by cylindrical supports which are positioned between neighboring exchanger tubes in order to prevent the medium from flowing between successive baffle plates.

  • Tube sealing in tube bundle heat exchangers
    Patent number: 4373580
    Abstract: A tube-bundle heat exchanger which allows replacement of the tubes. The heat exchanger tubes are held and sealed into a replaceable sealing arrangement consisting of an elastic sealing tube plate and two rigid tube plates arranged on either side which press the elastic sealing tube plate in the axial direction sealing the tubes. Force may be transmitted to the rigid tube plates by external means or by operating pressure of the media flowing in the heat exchanger.

  • Tube bundle heat exchanger
    Patent number: 4328862
    Abstract: A tube bundle heat exchanger including elastic sealing means wherein the elastic medium is confined within separate chambers and compressed in all directions against the inner wall surface of the chambers and heat exchanger tubes within the chamber. Pressure plates that exert pressure on the elastic medium are provided with projections which provide a spacing between the pressure plates. This spacing may be used for inspection for leaks and also permits flow of fluid to the outside if there is a leak.
