- the line regions between the heat exchanger block and the collector shown here in Figures 3 to 5 can be realized in each case by externally attached to the condenser piping, but also by a skillful interconnection of the inner disc elements and an arrangement of the collector directly to one of the outer surfaces of the heat exchanger block ,
- the individual connecting lines between heat exchanger block and collector can either be soldered directly to the heat exchanger block or subsequently realized by internal or external pipes. Likewise, it is providable to make the supply or discharge between heat exchanger block and collector via a corresponding design of the two outer Scheibeneiemente. For example, it is conceivable that channels are integrated into the two outer or in only one of the outer disk elements, which can be used as a supply or discharge.
- FIG. 8 shows a schematic sectional view of the capacitor. In particular, the individual disk elements can be seen » between which the channels are formed that belong to the first flow channel or to the second flow channel. The first flow channel is flowed through by a refrigerant.
- FIG. 6 illustrates the thermal separation layer 92, which is arranged between the condensation region 90 and the subcooling region 91 of the capacitor. The thermal separation layer 92 prevents unwanted heat transfer between the fluids in the subcooling region 91 and the condensation region 90.
- the thermal separation layer can be formed, for example, by an air-filled channel between two disk elements, by an air gap between two adjacent disk elements or an arrangement of several coolant channels next to each other.
- the aforementioned possibilities for forming a thermal separating layer are exemplary and have no limiting character.
- the heat transfer to the refrigerant ie a heating of the refrigerant is avoided.
