Definitions

  • the invention relates to an apparatus for the intensive exchange of heat between two hermetically separated media, a large surface area being achieved in that a multiplicity of thin-walled tubes are tightly connected in parallel without the use of tube sheets.
  • the currently known tubular heat exchangers all have in common that the tubes are inserted at both ends in perforated plates, and the tubes can be connected to the base and sealed by rolling, soldering, gluing or welding into the perforated base.
  • the invention has for its object to provide a light and inexpensive tubular heat exchanger made of corrosion-resistant material, in which the two media involved in the heat exchange are hermetically sealed, and in which at least the surfaces in contact with the media are designed so smooth that neither dreaded crevice corrosion can occur, dirt still carried in the medium can adhere to hard-to-clean limbs.
  • the individual tubes are expanded at their two ends to form an equilateral hexagon, the width across flats of which is just slightly larger than the tube diameter.
  • these pipes can be placed in parallel so that a honeycomb pattern is created on the front, with the individual pipes only touching each other along straight lines at the ends, while the cylindrical pipe middle parts keep a small distance from each other and so all-round washing of the pipe wall on the outside by one medium allow while the other medium flows through the tubes inside.
  • the tube ends are designed so that the hexagonal cross-section is maintained over several millimeters of tube depth, so that the tubes lie flat against one another on these hexagonal prisms.
  • the seal between the two media is now very easy to make, e.g. by gluing, soldering or especially welding the pipe ends along the hexagonal contact surfaces.
  • the tubes in the middle part can also have an elliptical cross-section instead of a cylindrical one, so that the medium flowing through the tube has a very favorable hydraulic diameter relative to the circumference and thus to the exchange surface, and for the outside Medium flowing around the pipes has a very low flow resistance based on the specific volume flow.
