Benefits of technology
The present invention provides a compact and economical condenser that can efficiently cool down a refrigerant and supply it for use. This invention has a simple structure and construction, making it an ideal choice for refrigeration systems.
Problems solved by technology
A drawback with the devices of the prior art is that the integration of condensers in stacked-plate construction, receivers and supercoolers is hitherto achieved in a very elaborate manner.
In addition to a complex structure, the condensers from the prior art are distinguished by an elevated production complexity.
This gives rise to additional costs in terms of using the condensers, which make their use unattractive.
However, as a result of the reduction of the heat transmission surface in the condensation region, which corresponds to the first region of the first flow channel, the heat transmission is worsened.
This impacts negatively on the pressure on the high pressure side crone refrigerant circuit, which, all in all, leads to a poorer system performance.
As a result, the heat transfer is particularly high.

Embodiment Construction
[0051]FIG. 1 shows a perspective view of a condenser 1 in stacked-plate construction. The condenser 1 here consists of a plurality of individual plate elements, which, stacked one on top of another, form the heat exchanger block 7. The heat exchanger block 7 is designed in its interior such that a plurality of channels are created between the individual plate elements. A number of these channels is assigned to a first channel, which can be flowed through by a refrigerant. A further number of the channels is assigned to a second flow channel, which can be flowed through by a coolant. Inside the heat exchanger block 7, the first flow channel is at least partially in thermal contact with the second flow channel, so that a heat transfer can take place between the first flow channel and the second flow channel.
[0052]By using various embodiments of the plate elements, the effect can be achieved that, inside the neat exchanger block 7, a plurality of flow paths for the first and second flo...

The invention relates to a condenser in stacked-plate design, wherein a heat exchanger block is formed by a plurality of plate elements, which form channels adjacent to each other between the plate elements when the plate elements are stacked on top of each other, wherein a first number of the channels is associated with a first flow channel and a second number of the channels is associated with a second flow channel, and a refrigerant can flow through the first flow channel and a coolant can flow through the second flow channel, wherein the first flow channel has a first region for desuperheating and condensing the vaporous refrigerant and a second region for subcooling the condensed refrigerant.
Description
TECHNICAL FIELD[0001]The invention relates to a condenser in stacked-plate construction, wherein a heat exchanger block is formed of a plurality of plate elements, which, stacked one on top of another, form mutually adjacent channels between the plate elements, wherein a first number of the channels is assigned to a first flow channel and a second number of the channels is assigned to a second flow channel, and a refrigerant is flowable through the first flow channel and a coolant is flowable through the second flow channel, wherein the first flow channel has a first region for the desuperheating and condensation of the vaporous refrigerant and a second region for the supercooling of the condensed refrigerant.PRIOR ART[0002]In refrigerant circuits of air conditioning systems for motor vehicles, condensers are used to cool the refrigerant to the condensation temperature and subsequently condense the refrigerant. Condensers regularly have a receiver in which a refrigerant volume is he...
