Definitions

  • the invention relates to a cross-flow cooler or heat exchanger, a flowing medium (heat exchange liquid) being cooled or heated by a cooling or heat flow running transversely to the direction of flow of the medium.
  • cross-flow heat exchangers usually consist of a device with horizontal lines (e.g. pipes or channels) for the heat exchange liquid and fans that generate an air flow that flows around the lines and thus the medium e.g. cools.
  • Water is often used as the heat exchange fluid.
  • the e.g. Radiator pipes can be emptied with compressed air, or it is necessary to add antifreeze.
  • the object of the invention is to provide an improved cross-flow heat exchanger which allows simple and automatic emptying of the line of the heat exchange liquid.
  • the invention is based on the basic idea of providing the otherwise horizontally running line of the heat exchange liquid with a slight slope so that, while observing the principle of the cross-flow heat exchanger, the heat exchange liquid can flow out of the line automatically when the heat exchanger is shut down.
  • the advantages of the invention lie in a quick and cost-saving emptying of the line of the heat exchange liquid and in the avoidance of additional work.
  • the cross-flow heat exchanger 1 consists of a housing 7 and fans 8 which suck air 4 through the housing from bottom to top.
  • lines (pipes) 2 for the heat exchange liquid one of which is shown in dash-dot lines, are arranged with a forward and a return line 2A and 2B, respectively, around which the sucked-in air flows.
  • fins are arranged on the tubes to improve the heat transfer.
  • the line 2 forms a loop with a slight slope and has an inlet 5 and an outlet 6 on one side (front side - left in FIG. 1)) of the heat exchanger 1.
  • the outgoing line 2A from the inlet 5 is at the bottom right inclined and the return line 2B inclined from the right to the bottom left to the drain 6.
  • the two pipe sections 2A and 2B are connected to one another via a U-pipe section 2C.
  • the respective inclination of the forward and return lines 2A and 2B with respect to the horizontal is in each case, for example, -1 to -2 ° or +1 to + 2 °.
  • FIG. 2 shows a front view of an embodiment according to the invention, each with two inflows and outflows 5 and 6 for the lines 2.
  • the inflows and outflows 5 and 6 are each connected in parallel through the distributor pipes 9 and 9 '.
  • the inflows and outflows 5 and 6 are laterally offset and in their continuation into the interior of the heat exchanger, the lines 2 form a laterally offset loop.
  • FIG. 3 shows a circuit diagram for the connections of the inflows and outflows 5 and 6 in an embodiment according to the invention with a large number of lines 2 (dashed lines).
  • the inflows 5 are arranged one above the other in levels A, B, C and connected via the lines 2 to the outlets 6 arranged in levels A ', B', C ', so that the lines 2 are nested, laterally offset loops nested inside the heat exchanger train with a slight slope.
