Definitions

  • the invention relates to a heat exchanger according to the preamble of claim 1.
  • heat exchangers are known, for example tubular heat exchangers, plate heat exchangers, etc. As different as they are in their nature, so are the fields of application. For example, heat exchangers are used for room ventilation, but are also used, for example, in Stirling engines or nitrogen engines. In addition to a high degree of efficiency and low production costs, a small space requirement and a high pressure and / or heat resistance are often required.
  • the object of the invention is to provide a heat exchanger which meets these requirements.
  • the heat exchanger is produced in a simple manner in that at least one sheet-shaped material is wound around the longitudinal axis of the heat exchanger. In cross section, a spiral with spaced windings is thus formed. The turns thus form the partitions while the channels are spaced through the space between the ones Turns are formed.
  • separating webs can additionally be provided between adjacent turns which extend along the heat exchanger from one end face to the other. Thus, a channel is formed between two turns and two separating webs.
  • the heat exchanger can be pre-produced by the meter with any number of turns and with any desired dimensions.
  • the channels are alternately flowed through in countercurrent of one or the other flow medium, between which the heat transfer takes place. That is, the innermost or first channel between the innermost or first turn and the second turn is flowed through by the one, for example, warm flow medium in one direction and the second channel between the second turn and the third turn of the other, colder flow medium in the opposite direction ⁇ tion, the third channel again from the warm flow medium, etc.
  • the flow medium can be both a gas and a liquid, but for example also a solid heat storage mass having a melting temperature below the temperature of the warm flow medium, for example paraffin, wax or fat.
  • the sheet-like material may be metal, plastic or another material, as long as it can be wound or produced in a gewi ⁇ ckelt.
  • the sheet-like material can be plastic.
  • a stainless steel sheet can be used.
  • the heat exchanger according to the invention has a high pressure and temperature resistance.
  • punctiform connection points can be provided between the windings, preferably in the longitudinal direction and around the circumference.
  • the individual channels are preferably closed at the end faces of the heat exchanger via a pitch circle and open at the other end face via a pitch circle. If the separating webs run parallel to the pole axis of the spiral, that is to say parallel to the longitudinal axis of the heat exchanger, the closed pitch circle of a channel preferably faces an open pitch circle on one end face on the other end face.
  • the flow medium does not flow straight through the channels, but is deflected in the circumferential direction, so that it emerges on the other end face, based on the cross section of the heat exchanger, on the Nielseneau ⁇ the side. In other words, if, in the case of a horizontally arranged heat exchanger, it enters the channel at the top or at the right in the channel, it exits at the other end side at the bottom or at the left.
  • the pitch circles are preferably formed by semicircles.
  • the open pitch circles or semicircles, via which the flow medium enters the heat exchanger, are preferably arranged on the same side or half of one side of the heat exchanger, and the open pitch circles or semicircles over which the other flow medium on the other end face in the opposite direction, on the wholie ⁇ ing side or half of the other end face. That is, in a horizontally arranged heat exchanger and extending parallel to the longitudinal axis separating webs, the open part or semicircles are hen vorgese ⁇ example, bottom or right for the entry of a flow medium, and the open part or semicircles on the other end face for the entrance of the other Flow medium in countercurrent top or left.
  • the connection of the heat exchanger is much easier, because the one Strö ⁇ tion medium at one end face and the other flow medium in countercurrent on the other end side in each case on one side or half of the respective end side can be connected sen sen.
  • the dividers can also extend helically around the polar axis of the spiral, ie the longitudinal axis of the heat exchanger.
  • the helix angle can be 180 ° or a multiple thereof.
  • the flow medium can in each case on the same side on the one end face and emerge on the other end face ren, ie. enter at a horizontally arranged heat exchanger in the upper half at one end face and emerge at the upper half from the other end face.
  • the heat exchanger according to the invention can be used in different fields. For example, it can be used in nitrogen engines in which liquid nitrogen is expanded with air, that is, in which the nitrogen forms the cold flow medium and the air or water countercurrently forms the warm flow medium. Another possibility is the Stirling machine, since the heat exchanger according to the invention is able to withstand a high pressure and high temperature.
  • the heat exchanger according to the invention can furthermore be used as an absorber for heat pumps, furthermore, for example as a water / air heater, eg as pre- or post-heating register. It is also ideal for geo-thermal plants.
  • the heat exchanger according to the invention can also be used to obtain thermo-power according to the Peltier effect.

  • the heat exchanger can also be used as a mixer. As shown in FIG. 8, the cover 18, from which the warmer flow medium emerges, then also extends over the bypass channel 16.
  • FIGS. 9 and 10 differs from that according to FIG. 5 essentially in that the two blades 10, 11 of each pair act at a first predetermined angle ⁇ and the inner blade 11 turns with the outer blade 10 of the adjacent inner Winding after a second predetermined angle ß, the predetermined to the first Angle ⁇ , are interconnected to form the channels 20.1, 20.2, 20.3 for one and 21.1, 21.2 and 21.3 for the other flow medium.

Abstract

Echangeur de chaleur pourvu de passages (3.1, 3.2,...) séparés par des parois de séparation, qui sont traversés en alternance à contre-courant par l'un ou l'autre des milieux d'écoulement (W, K). Ledit échangeur de chaleur est formé d'une matière (1) en forme de feuille enroulée en spirale. Les spires (2.1, 2.2,...) de la spirale forment les parois de séparation entre les passages (3.1, 3.2,...). Les passages (3.1, 3.2,...) sont en outre séparés les uns des autres par des nervures de séparation (4.1, 4.2,...) situées entre des spires voisines (2.1, 2.2,...).
