Definitions

  • the invention relates to a gas / liquid or gas / gas heat exchanger with layers, each having a plurality of mutually parallel one-piece heat-conducting fins, which transfer the heat from one medium to a second in a countercurrent process.
  • Air / water and air / air heat exchangers of various types are known. These have plates or lamellae and / or pipes, the two streams of air and / or water being conducted through lines or channels and, in the meantime, one of the two media giving off its heat to the other medium. The highest degree of temperature exchange is achieved with countercurrent heat exchangers.
  • the object of the invention is to provide a heat exchanger which has a very high degree of temperature exchange, is easy to repair and can be assembled and disassembled without great effort.
  • the heat exchanger is divided into heat exchanger layers, each of which forms a complete heat exchanger which guides both media and has a group of parallel heat-conducting fins, which are insoluble and are at the same height, that each layer is parallel to the other layers with their two inlets and outlets are separately connected to the main inlet and outlet lines of the entire heat exchanger, and that the layers are detachably connected to adjacent layers.
  • Such a heat exchanger is divided into individual, in the countercurrent principle heat exchanging and functional layer modules.
  • the required heat exchanger length can be selected for any heat exchange task, efficiently manufactured in modules and assembled on site at the application site. Transport and assembly are extremely simple and maintenance is not labor intensive. In the event of a defect, only the relevant heat exchanger layer needs to be repaired or replaced.
  • the heat exchanger Since the heat exchanger is divided into many individual layers, it can be used for heat exchange or for required temperature exchange degree required exchanger surface in front of each other - that is, in countercurrent - are arranged.
  • a block construction - as previously known - can be manufactured but is not practical. It is particularly advantageous if the height of each slat is a multiple of the distance between the slats. This means that the heat transfer takes place essentially over the fins and not over the walls separating the medium channels.
  • the lamella thickness is dimensioned in relation to the lamella material in such a way that low-energy loss heat conduction occurs.
  • a separating surface can be attached between the individual layers of the heat exchanger, which separates the medium flow of one layer from the medium flow of the adjacent layer. This means that cross turbulence is prevented and pressure losses are particularly low. Furthermore, the condensate that forms in one layer cannot run into other layers and can increasingly generate pressure losses there.
  • the fins extend into both media paths of different warmth, since it is ensured, in particular when the fins are narrow, that the heat transfer occurs essentially only via the fins and thus exergy losses are particularly low.
  • the heat flow from one medium to another is essentially only via the fins.
  • the gas / liquid, in particular air / water, heat exchanger shown in FIG. 1 is flowed through from right to left by gas or air and in the counterflow of liquid or water. It is divided into five layers 2, which form functional modules that each form a complete heat exchanger. Each layer 2 is connected separately at the inlet 3 and outlet 4 of the gas as well as at the inlet 5 and outlet 6 of the liquid, so that the entire gas flow and the entire liquid flow are divided into individual flows, a flow of both media being provided for each layer is and behind the heat exchanger these flows are again combined into a total flow. While the gas streams 7 flow straight through the individual layers, the liquid flows back and forth in a pipe coil 8 in each layer 2, whereby the liquid stream crosses and flows against the air stream.
  • each layer 2 numerous fins 9 are fastened to the tubes 8 parallel to the gas flow, the fins 9 being perpendicular to the regions of the tubes 8 which run through the family of fins.
  • the lamella thickness is dimensioned in relation to the lamella material in such a way that low-energy loss heat conduction occurs.
  • a separating surface 10 which separates the gas paths of each layer.
  • each layer is connected at the beginning and end of the layer via a valve 11 to the inlet 5 and outlet line 6, respectively, so that the layers can be vented when they are put into operation for the first time and after closing two valves 11 each layer is easily taken out of operation, checked , can be cleaned or dismantled on the liquid side without disassembly.
  • the gas / gas, in particular air / air, heat exchanger shown in FIGS. 3 and 4 can have exhaust gas (exhaust gas) or outside air 12 flowing through them from left to right and a second gas stream 13 flowing from right to left.
  • the heat exchanger is divided into five individual, functional layer modules 2, each module having finned heat-conducting surfaces in order to extract and transfer heat from the gas flows flowing in countercurrent.
  • Each layer 2 has a separating plane 14 in the center, on which the slats 9 are fastened at right angles and parallel to one another. The two gas streams are separated from one another by these levels 14, so that apart from the outer areas, i.e. 4 the upper and lower region, the gas flows each flow through two adjacent layers 2.
  • Each layer 2 is connected separately from the other layers to the inlet and outlet of both gas streams, so that, as in the first exemplary embodiment, both media streams are divided and flow through each layer with partial streams and are then led to the two outlets without leading to one to get to the next layer.
  • the lamellae 9 thus extend into the paths of two different media, and the lamellae 9 are so close together that a heat flow essentially only via the slats.
  • the height of the slats H is a multiple of the distance A from each other.
  • the lamella thickness is dimensioned in relation to the lamella material in such a way that low-energy loss heat conduction occurs.
  • Parallel separating surfaces 10 are arranged between the individual module layers 2 of the heat exchanger, and the same medium flow flows around them on both sides.
  • each layer 2 is releasably attached to the adjacent layer or layers, so that they can be easily replaced and assembled and removed.
  • Both heat exchangers can be used not only in the horizontal position shown in the figures, but also in other positions, in particular in a vertical position.
  • the degree of temperature exchange is 75 to 90%.
