Definitions

  • the invention relates to a radiator, in particular for a motor vehicle, having at least one coolant line device, in particular a plurality of coolant line devices, such as pipes, through which a cooling medium to be cooled flows.
  • the object of the invention is to provide a cooler, in particular for a motor vehicle, with at least one coolant line device, in particular a plurality of coolant line devices, such as pipes, which is or are to be flowed through by a cooling medium to be cooled, which has a better efficiency than conventional coolers.
  • the object is achieved in a cooler, in particular for a motor vehicle, with at least one coolant line device, in particular a multiplicity of coolant line devices, such as pipes, through which a cooling medium to be cooled flows, or are thereby dissolved, the coolant-conducting device is formed integrally from two parts, in particular halves, which are connected to one another by a bending edge running in the longitudinal direction of the coolant-conveying device. Since the two parts or halves are already connected to one another at the bending edge in one piece, they only have to be soldered together on one side. As a result, the cross section through which the cooling medium flows increases. In addition, the number of individual parts required is reduced by half, since only one part is required per coolant line device.
  • a preferred exemplary embodiment of the cooler is characterized in that the coolant line device is formed by a substantially rectangular plate, which is divided by the bending edge into two elongate halves which are folded together.
  • the plate is preferably an embossed stamped part made of a metallic material which can be produced simply and inexpensively. In the folded state, the plate halves are congruent to each other.
  • the plate has a peripheral edge which is opposite the plate surface.
  • the plate is impressed within the peripheral edge, wherein the depth of the embossed surface is half the inside diameter of the coolant line device.
  • Another preferred exemplary embodiment of the cooler is characterized in that the peripheral edge is interrupted at the points of intersection with the bending edge. In the area of the bending edge, the plate has the same depth over the entire length of the bending edge. This avoids unwanted damage to the plate material in the region of the bending edge during folding.
  • Another preferred exemplary embodiment of the cooler is characterized in that the two plate halves rest against each other in the folded state with the peripheral edge. Preferably, the plate halves are soldered to each other at the peripheral edge.
  • Another preferred exemplary embodiment of the cooler is characterized in that in each case a connecting piece is formed at the ends of the plate halves.
  • the connection stubs are preferably formed by deep-drawn cups, which serve to connect two superimposed coolant line devices with one another. This has the advantage that separate connecting pipes can be omitted.
  • Another preferred exemplary embodiment of the cooler is characterized in that a plurality of elevations are formed on each plate half, which abut one another in the folded state of the plate halves.
  • the elevations which are soldered together are preferably embossed studs which contribute to improving the heat transfer and as tie rods to increase the strength.
  • Another preferred exemplary embodiment of the cooler is characterized in that a turbulence insert is arranged between two folded plate halves.
  • the preferably soldered with the plate halves turbulence insert serves to improve the heat transfer and as a tie rod to increase the strength.
  • a further preferred exemplary embodiment of the cooler is characterized in that a plurality of coolant line devices are stacked on top of one another and in each case an air guide device is arranged between two coolant line devices.
  • the louver preferably comprises a plurality of air guide ribs which are integrally connected to each other.
  • a further preferred exemplary embodiment of the cooler is characterized in that the coolant line device and the air guide device are formed from the same sheet metal material, in particular from aluminum sheet. This has the advantage that the complete radiator is formed only from one material and is therefore easily recyclable. - A -
