Definitions

  • Spiral heat exchangers are technical devices that are relatively small Construction volume a high effective heat exchange between the same or allow different media.
  • spiral heat exchangers Another peculiarity of the known spiral heat exchangers are their relative high pressure drops. If these are to be reduced, however, the compactness limited.
  • This spiral heat exchanger is also designed as a so-called safety spiral heat exchanger with only one exceptionally high effort possible.
  • the object of the invention is based on the prior art to create a spiral heat exchanger that is avoiding of the disadvantages mentioned above is simple and, in particular in mass production for integration in automobiles with fuel cells, can be manufactured efficiently and inexpensively.
  • Such a spiral heat exchanger comprises at least two spiral elements, in which media of different temperatures flow. It can different media or identical media. Every spiral element is made up of a partially longitudinally slit central tube with at least a front media connection as well as one in the area of the longitudinal slot transversely attached to the central tube, spirally around the Central tube curved multi-channel profile together, the width of one Multiple times the height. The end section facing away from the central tube defines an overflow area for a medium. Each in heat exchange standing media enter a multi-channel profile through a central tube and flow in this up to the overflow area. This can be connected to the overflow area of another spiral element be axially attached to the first spiral element.
  • a spiral element can but also by an appropriate inner design one from the central tube to an overflow area and from this overflow area again complete flow path directed back to the central tube for a medium have.
  • a spiral heat exchanger designed in this way guarantees a perfect heat exchange between the Media in the intimately surrounding spiral elements.
  • the supply and discharge The media is only supplied via the core area of the spiral heat exchanger central tubes.
  • Each spiral element can have several spiral elements nested tightly one inside the other and, depending on the application, also carry more than two media.
  • the spiral heat exchanger is therefore extremely compact and can be used high exchange performance can be configured comparatively small volume. This makes the use in automobiles with fuel cells particularly advantageous.
  • the invention allows only the spiral elements to carry the media or additionally the areas between two nested ones Spiral elements are loaded with at least one medium.
  • the Areas between the spiral elements are then optionally over a multi-channel central feed pipe and also under Under certain circumstances, multi-channel central discharge pipe with feed and discharge lines connected.
  • the invention allows the radial width of the spiral elements can be designed differently, so that the throughput quantities can vary.
  • thermodynamic efficiency By dividing a single media stream into a larger number of spiral elements with a reduced radial width per media stream can also reduce the pressure drop while at the same time Improvement in thermodynamic efficiency can be effected.
  • the Spiral heat exchanger no complicated, especially spiral, To be welded.
  • the connections of the multi-channel profiles the central tubes are only through longitudinal seams, in particular through Welding ensured. Due to the multi-channel nature, the flow paths are short. This results in low temperature stresses.

  • a performance adjustment be made during operation. So the entire facility for example when starting with a lower output and smaller ones Exchanger surfaces are operated. Only after reaching the full load situation all exchanger surfaces are switched on. Depending on the current The entire facility can then operate with the optimal efficiency. Also a shutdown a spiral heat exchanger or several spiral heat exchangers during an operation is quite possible.

This is e.g. then expedient if the spiral heat exchanger is used as an evaporator, for example of gasoline, as part of a so-called fuel cell to be used. It is to accelerate the evaporation effect then it makes sense to set the spiral heat exchanger in rotation. Because of the medium to be evaporated accelerates during rotation in the radial direction, associated with an increase in pressure, which in turn is synonymous with faster evaporation.
  • the spiral heat exchanger according to the invention When the spiral heat exchanger according to the invention is used as a compressor should be, especially if air is to be compressed, so becomes an acceleration due to the rotation of the entire spiral heat exchanger the air reaches in the radial direction. This is an increase pressure, which leads to faster compression of the air.
