Definitions

  • the present invention is based on the general idea of designing a flat tube for a heat exchanger in such a way that the flat tube can be flowed through by an associated fluid both in the longitudinal direction and at least partially perpendicularly or transversely to the longitudinal direction and thus has a flow direction component perpendicular to the longitudinal direction.
  • This makes it possible, in a designed according to the cross-flow principle heat exchanger in which the heat-exchanging fluids, fluidly separated, cross, increase the degree of heat exchange.
  • the flat tube has an inlet for introducing the first fluid into the flat tube and an outlet for discharging the first fluid from the flat tube, which are arranged at longitudinally opposite ends of the flat tube or along the end side of the flat tube.
  • the outlet and the inlet are each limited only to a partial cross-sectional area of the flat tube and arranged diagonally opposite one another.
  • flow elements are also provided in the flat tube, wherein the flow elements can be flowed around by the first fluid such that the first fluid has the flow direction component perpendicular or transverse to the longitudinal direction.
  • the amplification of the flow direction component perpendicular to the longitudinal direction may in this case be conditioned both by the design and by the arrangement of the flow elements.
  • the flow elements are preferably designed such that they build a pressure gradient in the transverse direction, such that the first fluid flows in the transverse direction and thus has the flow direction component perpendicular to the longitudinal direction.
  • the flow elements are preferably arranged in the flat tube or within the flat tube.
  • the flat tube has larger dimensions in the transverse direction than a thickness running transversely to the transverse direction and transversely to the longitudinal direction.
  • the extent of the flat tube in the transverse direction can be at least twice as large as the thickness.
  • the flat tube has a transversely extending inlet section, a transversely extending, in particular spaced from the inlet section, outlet section and a transversely disposed between the inlet section and the outlet section heat exchange section.
  • the inlet section includes the inlet
  • the outlet section includes the outlet.
  • the flow elements are arranged in the heat exchange section.
  • inlet section and outlet section are free of flow elements. This advantageously combines the advantages of the diagonal arrangement of the inlet and outlet as well as the flow elements.

  • embodiments in which the flow elements are arranged by rows spaced apart in the longitudinal direction in the rotor assembly relative to one another are particularly preferred. That means that the Flow elements of longitudinally adjacent lines, in particular of lines adjacent to each other in the longitudinal direction, are arranged transversely offset.
  • the flat tube with at least two columns of such flow elements, wherein the respective column has at least two longitudinally spaced flow elements and wherein the columns are spaced from each other in the transverse direction.

It is furthermore preferred if the flow elements are arranged offset in the longitudinal direction by columns which are adjacent in the transverse direction, in particular by gaps lying next to one another in the transverse direction, in particular in the form of a rotor bandage.
  • the flow elements are arranged such that a diagonal meandering flow of the fluid results in the flat tube. This is achieved in particular by such columns of flow elements.
  • the respective flow element can be configured as desired, provided that, at least with further flow elements, it leads to a flow direction component of the first fluid perpendicularly or transversely to the longitudinal direction.
  • the design of the respective flow element as a turbulator, a dimple, an inner rib, an embossment and the like is to be considered. It is also conceivable to design at least one such flow element as a porous structure. Also to be considered is variants in which at least one such flow element is a porous one Material, in particular a metal foam, or is formed as such a material, in particular metal foam.
  • the flow elements of the flat tube may have different shapes and / or sizes. It is also conceivable that the flow elements of the flat tube have a same shape and / or size.
  • the flow elements are formed as integral parts of the flat tubes, which significantly simplifies the production.
  • the flow elements are designed as inwardly directed deformations of the flat tube, in particular as embossing, for example as a dimple.

  • the flat tube according to the invention is preferably used in a heat exchanger which additionally has two opposing collectors for collecting and / or distributing the first fluid into the flat tube or from the flat tube.
  • One of the collectors may be formed as an inlet header for introducing the first fluid into the downcomer and the other header as an outlet header for discharging the first fluid from the flat tube.
  • the respective collector distributes the fluid between different flat tubes, ie both as an inlet collector and as Outlet collector acts or designed as a deflector. In the collectors and the flat tube thus flows the first fluid.
  • the flat tube is in this case flows around the second fluid.
  • the second fluid flows through the heat exchanger against the transverse direction or against the flow direction portion of the first fluid perpendicular to the longitudinal direction of the flat tube, such that the flat tube is flowed against the transverse direction of the second fluid.
  • This cross counterflow allows particularly high heat exchange rates between the first fluid and the second fluid and thus a particularly high efficiency of the heat exchanger.
  • the respective collector may have a bottom with passages in which the flat tubes are accommodated along the end.
  • the inlet and the outlet of the flat tube are each in fluid communication with the associated collector.
  • two or more such flat tubes can also run between the respective inlet header and the respective outlet header, wherein at least one such flat tube is designed according to the invention.
  • the heat exchanger can be used in any application for heat exchange between two fluids.
