- the invention has for its object to provide a capacitor of the type mentioned, with which it is possible that available cooling water for optimum heat transfer of cold media! to use the coolant, without causing too high pressure drops. Furthermore, the present during the condensation temperature profile should be able to be carried out more advantageously.

- Advantageous embodiments are the subject of the dependent claims.
- the object is achieved according to the invention in that the ratio of the two hydraulic diameter (D h coolant ) to (D h refrigerant ) is greater (>) 1, 3.
- the hydraulic diameter D h is a theoretical quantity to perform calculations on pipes or channels of non-circular cross-section. With the term can be expected as a round tube. It is the quotient of the fourfold flow cross section A and the circumference U wetted by the fluid (if applicable, inside and outside) of a measuring cross section.
- the hydraulic diameter (D h coolant ) can be between 1, 5 mm and 3 mm.
- the hydraulic diameter (D h coolant ) is defined, for example, by means of an intermediate element which may be designed in the manner of a turbo-molder.
- the intermediate element has a hydraulic diameter between 1, 5 mm and 3 mm.
- the flat tube and the intermediate element are heat-conductively connected to each other » soldered, for example.
- a combination takes place between the flat tube and the intermediate layer, through which the coolant flows past the flat tube in countercurrent or constant flow.
- a preferred embodiment for obtaining the specified cold-side flow cross-section is, for example, a flat tube with a plurality of flow channels.

- the flow cross-section of the refrigerant-side flow channels has a substantially right angular cross-sectional shape, wherein the width b of each flow channel is preferably at least slightly smaller than its height h.
- extruded flat tubes are used for the refrigerant flow. These consist for example of a pipe jacket and have to increase the strength and increase the heat transfer surface inner webs.
- a preferred tube has a greater height than width, since in this case by capillary effects, an additional performance advantage can be achieved.
- the flow cross-section of each tube is characterized by the hydraulic diameter.

- the refrigerant-side flow path is switched degressively, such that the flow cross-section of the last refrigerant-side flow path is at least slightly smaller than the refrigerant-side flow path of the first flow path.
- degressive means the relationship between two sizes, for example, when the hydraulic diameters and flow paths of coolant and refrigerant are adapted to the respective flow velocities or if the other increases as one of the sizes increases.
- the condenser itself the refrigerant is cooled down to its condensation temperature. Subsequently, the condensation of the refrigerant takes place before a further supercooling of the refrigerant to a temperature below the condensation temperature.

- the refrigerant flow is guided through the component in a plurality of flow paths arranged one behind the other, which have a flow cross-sectional area decreasing from path to path (-> degressive
- the refrigerant is first de-oiled, then condensed in the component (where the temperature remains constant over a wide range) and then subcooled. Therefore, in practice, the following requirements for the guidance of the coolant flow; the cooling center! should be introduced into the condenser in the area of subcooling and then run countercurrently;
- the constant temperature on the refrigerant side does not matter whether the flow is conducted in countercurrent or direct current
- the refrigerant should be run out of the apparatus in countercurrent overheating. This optimizes the driving temperature gradient in the heat exchanger / condenser and thus achieves high performance.
