Definitions

  • the invention relates to a plate heat exchanger comprising a dryer and a water-cooled condenser, the condenser comprising a plurality of plates and two end plates, possibly with an integrated receiver.
  • the invention further relates to a plate for a plate heat exchanger having an opening, and its use.
  • Plate heat exchangers are a special design of a heat exchanger which consist of plates which are assembled in such a way that the medium to be heated up and then the heat-emitting medium flows in the successive interspaces in each case.
  • the plate pack is sealed to the outside and between the media.
  • water-cooled condensers are fabricated in a plate-plate or plate-lamellar design. Due to the design of water-cooled condensers, drying agent is introduced and stored in a separate external refrigerant collector dryer container.
  • FR3001795 B1 discloses a plate heat exchanger for an air conditioning circuit in which a plurality of plates that are arranged between two end plates, are interconnected.
  • the plate heat exchanger has a cylindrical collector dryer which is arranged (externally) on one of the two end plates, as shown in FIG. 1 .
  • a dryer that is arranged externally on one of the end plates has the disadvantage that the dimensions of the water-cooled condenser assembly are enlarged.
  • connecting pipes or a connecting block are/is required.
  • screw-on receiver drier bottles sometimes require an additional assembly process.
  • the object of the invention is to provide a heat exchanger, which has smaller dimensions and is inexpensive to manufacture.
  • the object of the present invention is achieved by a plate heat exchanger of the afore-mentioned type in which the collector dryer is integrated in the condenser, the plates have an opening, wherein the opening is designed such that when a plurality of plates are arranged side by side, the openings in the plates form a cavity, and/or at least one of the end plates has a cavity, wherein the cavity is suitable for receiving a dryer and/or a drying agent.
  • the collector dryer or the receiver dryer bottle is arranged in the inner part of the condenser, has a comparatively smaller dimension of the condenser, which is particularly advantageous when installing the heat exchanger in a motor vehicle.
  • the manufacture of the heat exchanger is simplified and the costs of the heat dryer are thus also reduced.
  • Another advantage of such an embodiment is that the dimensions turn out to be smaller compared to a design in which a receiver dryer bottle is attached externally to the condenser.
  • additional components such as connecting pipes or a connecting block with which the receiver dryer bottle is connected to the condenser can be dispensed with.
  • the inner part of the condenser is preferably formed by brazing, such as, for example, vacuum brazing, in a plate-plate or plate- (cooling) fin configuration, wherein the condenser has refrigerant-carrying layers (refrigerant channels) and water-carrying layers (water channels).

  • the dryer preferably has at least one dryer opening, wherein the at least one dryer opening is designed such that the dryer opening is connected to the refrigerant-carrying layer or one or more of the refrigerant channels so that refrigerant can be channeled into the dryer.
  • This allows the refrigerant to flow through the drying agent arranged in the cavity, or to be in material contact with said drying agent and to bind the liquid.
  • a flow-through through the drying agent is not necessary, an opening as a means for diffusion is enough.
  • the drying agent attracts the moisture, wherein in this case water from the heat-receiving or heat-emitting medium does not flow through the dryer.
  • the cavity formed by the plates is connected to the refrigerant filled space of the condenser via the at least one dryer opening.
  • the at least one dryer opening is preferably arranged in one or more of the refrigerant-carrying layers of the condenser, or connected to one or more of the refrigerant channels.
