Definitions

  • a heat exchanger with at least one inflow channel and at least one outflow channel and at least one collector, which has at least two adjacent plates and with a flow device, which can be flowed through by a first medium and a second medium, wherein the first Medium is distributed from an inflow channel to the collector and to the flow device and can be conducted to an outflow, provided, wherein at least one further channel for distributing the refrigerant is provided, which is communicatively connected by at least one opening with the inflow channel.
  • the openings are arranged along the entire length of the further channel.
  • the number of openings corresponds to the number of flat tubes, so that an opening in the further channel is provided for each flat tube, which is preferably in the immediate vicinity of the respective flat tube.
  • two or more further channels are arranged within the inflow channel.
  • the refrigerant flows in this case first into the first further channel, then into the further channels and finally into the inflow channel, from where the refrigerant is distributed to the flow device.
  • two or more further channels are arranged outside the inflow channel and connected to each other in a serial communication.
  • the refrigerant therefore flows first into the first further channel, then into the further channels and finally into the inflow channel, from where the refrigerant is distributed to the flow device.
  • the two or more further channels can be embodied, for example, as tubes or as plates, which stacked form cavities in which the refrigerant is distributed to the inlet channel and the flow-through device.
  • the two openings 19 communicating the further channel with the inflow channel are arranged substantially on opposite sides of the further channel and in alignment in a direction perpendicular to the evaporator level.
  • FIG. 9 to 11 three further embodiments of an inflow channel according to the present invention are shown in a side view.
  • the Fig. 12 shows a front view of the fourth embodiment according to Fig. 11 .
  • the two openings 19 are spaced from the center of the inflow channel.
  • the further channel 4 is closed in the flow direction after the openings 19 by a partition wall 22 to counteract a negative effect of the refrigerant backflow.
  • the further channel is concentric or eccentric in the inflow channel (see 11 and FIG. 12 ).
  • the fifth embodiment is shown in a side and front view.
  • the further channel 4 is inserted in the inlet channel 2 and has a recess 23, so that there is a longitudinal gap 24, in which the refrigerant is distributed through the openings 21 to the tubes.
  • the course of the at least one opening 19 is formed substantially perpendicular or obliquely to the inflow channel.
  • Fig. 23 shows the ninth embodiment and a development of the heat exchanger according to the FIGS. 21 and 22 .
  • the inflow channel, the outflow channel and the further channel are designed as tubes in triangular shape.
  • the at least one opening which communicates the further channel with the inflow channel is preferably arranged in the middle or at any other points of the further channel and the inflow channel.
  • the tenth embodiment is shown in a front view.
  • the inflow channel, the outflow channel and the further channel are formed by deformed metal sheets which are connected to one another in a positive and / or cohesive manner.
  • the cross sections of the inlet and outlet are substantially semicircular and the cross section of the further channel is substantially circular.
  • any other shape of the cross section is possible. With this configuration, a particularly favorable production method of the various channels is possible.
  • the two half shells 2a and 2b are in particular positively and / or materially connected to each other, for example, clipped together.
  • alternative has a half-shell crenellated projections 28 which engage in corresponding recesses of the other half-shell ( Fig. 41 ).
  • the invention has been explained with reference to a heat exchanger in which the refrigerant flows parallel to the inlet channel in the heat exchanger.
  • the refrigerant flows perpendicular to the inflow in and / or out of the heat exchanger.
  • the inlet and / or outlet openings are in this case in the middle of the inflow and / or outflow or spaced from the center.
