Definitions

  • the invention relates to a condenser for an air conditioner, in particular a motor vehicle according to the preamble of patent claim 1.
  • Condensers for air conditioning systems are arranged in the front engine compartment of a motor vehicle, usually together with a cooler as a so-called cooling module and are flowed through by ambient air, ie the wind of the motor vehicle or a fan-assisted air flow.
  • a cooling module consisting of coolant radiator and condenser, also associated with a charge air cooler, which is arranged in the air flow direction in front of the capacitor and covers a lower portion of the end face of the capacitor.
  • a condenser for an automotive air conditioning system consists of a finned tube block, the tubes are flowed through by a refrigerant, which is distributed over laterally arranged from the block manifolds, deflected and collected.
  • Capacitors are often flowed through with multiple floods, ie from the inlet of the gaseous refrigerant to the outlet of liquid refrigerant.
  • the last through-flowed tubes of the block form a so-called subcooling section (also: subcooling), in which the already liquid refrigerant is cooled below its condensation temperature.
  • subcooling section also: subcooling
  • the installation conditions for the installation of a capacitor in the front engine compartment of a motor vehicle are very different: sometimes there are limitations in the width, some restrictions in the height of the installation space and sometimes the ventilation conditions for the capacitor are different, for example, with additional arrangement of a charge air cooler in the air flow direction the capacitor. In this case, an undercooling line below is insufficiently cooled.
  • the collector or the dryer bottle is arranged above the condenser block. This results in the advantage of a smaller installation width for the condenser, consisting of Kondensatvrblock and laterally arranged headers,
  • the capacitor is designed as a cross-flow capacitor with an overhead subcooling, d. H. it is traversed essentially from bottom to top of multiple fl ow of refrigerant.
  • the collector by means of holders on the capacitor block, preferably attached to the side part.
  • the holder can thus be formed as sheet metal parts, which are soldered to the collector.
  • the collector arranged substantially above the condenser block is offset or arranged in the air flow direction in front of or behind an end face of the condenser. This results in the advantage of better space utilization and a slightly lower height.
  • Fig. 1 shows a capacitor 1 for a motor vehicle air conditioning system, not shown.
  • the condenser 1 is designed as a cross-flow condenser with a condenser block (also called fins / tube block) consisting of non-illustrated flat tubes and corrugated fins and has two laterally and vertically arranged headers 3, 4 - in this position, the condenser 1 is not in the illustrated front engine compartment of the vehicle installed and there flows through ambient air or the wind, which enters through a grill, not shown, in the front region of the vehicle.
  • At the two manifolds 3, 4 holders 5, 6, 7, 8 are fixed, with which the capacitor 1 in the vehicle in a manner not shown, for. B. is attached to a coolant radiator.
  • the condenser 1 is flowed through by a plurality of refrigerant, which enters via a refrigerant inlet line 9 into the collector 4, which is divided into chambers, not shown.
  • the approximately 40 tubes having condenser block 2 is four-flow flows through from bottom to top, wherein the flow cross-section of each through-flow in one tubes decreases gradually.
  • a so-called subcooling path UK which consists of about four pipes, not shown, which lead substantially liquid refrigerant and open into an upper chamber 4a of the manifold 4.
  • a collector 10 which is known per se is arranged, which is of tubular design and is also referred to as a dryer bottle because it contains a dryer, not shown here.
  • the collector 10 is arranged substantially horizontally and fixed to the capacitor block 2.
  • the interior of the collector 10 is connected via a short line section 11 with the upper chamber 4a of the manifold 4 and thus with the subcooling UK.
  • the collector 10 also serves for the storage of refrigerant.
  • the refrigerant passes from the collector 10 to a connection flange 13, via which the condenser 1 can be connected to a refrigerant circuit, not shown.
  • FIG. 2 shows a perspective view of the upper part of the capacitor 1 according to FIG. 1 in a view from the rear, ie the capacitor 1 is rotated approximately 180 degrees about its vertical axis relative to the view in FIG.
  • the collector 10 is attached via two holders 14, 15 on the capacitor block 2, which has on its upper side a side part 12, consisting of a flat or profiled sheet.
  • the entire capacitor 1 is brazed, ie also the side part 16 is soldered to the block 2 and thus forms a stable base for holding the collector 10. It can be seen from this illustration that the upper subcooling UK is undisturbed by air can flow and thus is well cooled.
  • Fig. 3 shows the capacitor 1 (again the same reference numerals are used for the same parts) in a side view, ie with a view towards the manifold 3, wherein the capacitor 1, however, is slightly inclined towards vome, so that the side part 16 is shortened recognizable.
  • the holders 14, 15 are inclined slightly upwards relative to an imaginary horizontal and at the same time act as spacers between the collector 10 and the condenser block 2-
  • the air flow direction is represented by an arrow L, ie in the drawing from left to right;
  • the reverse direction represented by a dashed arrow L ', is also possible. In both cases, the above-lying subcooling UK is flowed virtually undisturbed, even in the air flow direction L '.
  • the collector 10 is - as the drawing shows - arranged offset in the air flow direction L relative to the capacitor block 2, wherein at the same time a certain overlap between upper edge block 2 and lower edge collector 10 results. It is essential, however, that both subcooling UK and collector 10 are at the top, ie have approximately the same height and thus only a short connection on the refrigerant side.
  • the connecting flange 13 takes - as well recognizable here - the refrigerant inlet line 9 and the refrigerant outlet line 12 in corresponding holes and connects both in a manner not shown with corresponding mating connections of the refrigerant circuit, not shown, the motor vehicle air conditioning.
