Definitions

  • the invention relates to a manifold for a heat exchanger apparatus, according to the preamble of independent claim 1, a heat exchanger apparatus according to the preamble of independent claim 9 and a method for emptying a heat exchanger apparatus according to the preamble of independent claim 12.
  • EP 1 811260 A2 describes such a manifold.
  • Heat exchanger devices can be found in a variety of technical applications, such as refrigeration and domestic refrigeration equipment and devices, in heating and air conditioning systems for buildings or transportation such as cars, buses, ships and airplanes, or as coolers in power plants, internal combustion engines, computers, or other heat generating facilities.
  • the heat exchanger device is often connected to a circuit containing a fluid, ie a heat transfer medium, for example, a coolant, the heat exchanger devices heat directly, ie without phase change from the liquid or gaseous fluid record or deliver to the same, or as a capacitor or evaporator for the fluid can be effective.
  • a laminated heat exchanger device consists of a tube for the passage of a fluid and of a plurality of fins which are connected to the tube and in operation communicate with a second medium.
  • This design is particularly useful when the second medium is gaseous and, for example, consists of ambient air, since this has a comparatively low heat transfer coefficient, which can be compensated by a correspondingly large surface of the slats.
  • the laminated heat exchanger device may also contain a plurality of tubes for more than one fluid, or the tubes may be connected in parallel and / or in series as needed.
  • the efficiency is essentially determined by the temperature difference between the fins on the one hand and the or the pipes on the other hand.
  • the temperature difference is the smaller, i. the more effective the heat transfer, the greater the conductivity and the thickness of the fins, and the smaller the mutual distance of the tubes. In terms of efficiency, it is thus advantageous if many tubes are used. However, many tubes also mean higher material and processing costs, so higher efficiency is usually associated with higher costs.
  • the well-known laminated heat exchanger device serves to transfer heat between two media, eg for transferring a fluid to air or vice versa, as is known, for example, from a classic household refrigerator, over the heat exchanger device to produce a heat exchanger device Cooling power inside the refrigerator heat is dissipated to the ambient air.
  • the second medium outside the heat exchanger device for example water, oil or often simply the ambient air, for example, absorbs the heat or is transferred from the heat to the heat exchanger device is either cooled or heated accordingly.
  • the second medium eg the air
  • the medium with the high heat transfer coefficient flows in the tube, which on the outside by thin sheets (ribs, fins) has a greatly enlarged surface at which the heat transfer takes place, for example, with the air.
  • this so-called laminated heat exchanger device is carried out according to a long-known standardized process:
  • the slats are punched with a press and a special tool and put into packages to each other.
  • the tubes are inserted and expanded either mechanically or hydraulically so that a very good contact and thus a good heat transfer between the tube and lamella arises.
  • the individual tubes are then connected by arches and manifold and manifold, often soldered together.
  • the efficiency is essentially determined by the fact that the heat that is transferred between the fin surface and the air, must be transmitted through heat conduction through the fins to the pipe.
  • the pipe spacing should be as small as possible, but this leads to the problem that you need many pipes.
  • many pipes also entail high costs because the pipes (usually made of copper) are considerably more expensive than the thin fins.
