Definitions

  • the invention relates generally to a radiator intended especially for motor vehicles.
  • the invention is directed to a radiator including a plurality of cooling tubes arranged in a U-shaped, wherein each of the cooling tubes has a helical portion.
  • Radiators in the art often include tube bundles for passing a medium therethrough.
  • An example of a conventional tube bundle is described in Chinese Utility Model Pat. Pub. No. CN 201221907Y, in which a radiator includes a plurality of U-shaped tubes, each of the tubes including a helical groove with a constant pitch and a constant depth.
  • Another similar example is described in German Pat. Appl. Pub. No. DE 102007013302, in which a radiator includes a plurality of U-shaped tubes, each of the tubes including a smooth surface.
  • a flow of a fluid in a conventional tube bundle including a plurality of cooling tubes arranged in a U-shaped configuration is unevenly distributed in the tubes.
  • the uneven distribution of the fluid leads to less than optimal operation and a drop in the pressure value in the radiator.
  • a radiator having a plurality of cooling tubes arranged to provide a substantially uniform distribution of fluid in the tubes without a drop in a pressure value in the radiator has surprisingly been discovered.
  • a radiator comprises: a supporting part including a plurality of through openings formed therein; and a plurality of cooling tubes, each of the cooling tubes received in at least one of the through openings formed in the supporting part, each of the cooling tubes having a generally U-shaped configuration, wherein a first one of the cooling tubes includes a first helical portion having a first pre-determined depth and a second one of the cooling tubes includes a second helical portion having a second pre-determined depth different from the first pre-determined depth.
  • a radiator comprises: a supporting part including a plurality of through openings formed therein; a first cooling tube received in at least a first one of the through openings formed in the supporting part, the first cooling tube having a first helical portion with a first pre-determined depth; and a second cooling tube received in at least a second one of the through openings formed in the supporting part, the second cooling tube having a second helical portion with a second pre-determined depth, wherein the second pre-determined depth is greater than the first pre-determined depth.
  • a radiator comprises: a supporting part including a plurality of through openings formed therein; a first cooling tube received in at least a first one of the through openings formed in the supporting part, the first cooling tube having a helical portion with a first pre-determined depth; a second cooling tube received in at least a second one of the through openings formed in the supporting part, the second cooling tube having a helical portion with a second pre-determined depth, wherein the second pre-determined depth is greater than the first pre-determined depth; and a third cooling tube received in at least a third one of the through openings formed in the supporting part, the third cooling tube having a helical portion with a third pre-determined depth, wherein the third pre-determined depth is greater than the second pre-determined depth.
  • FIG. 1 illustrates a radiator according to an embodiment of the present invention.
  • the radiator includes a supporting part 1 , which is provided with an even number of through openings arranged one above the other (i.e. in a linear configuration).
  • six openings are arranged in the supporting part 1 for securing the ends of a plurality of U-shaped cooling tubes 2 .
  • the U-shaped portion of the cooling tubes 2 are concentrically arranged to substantially align the ends of each of the cooling tubes.
  • each of the cooling tubes 2 is arranged adjacent each other along a single plane.
  • any number (e.g. eight, ten, or more) of paired openings can be formed in the supporting part 1 .
  • each of the cooling tubes 2 includes a helical portion/design 3 (e.g. groove).
  • a depth h 2 of the helical portion 3 created on an intermediate cooling tube 2 a of the radiator is less than a depth h 1 of the helical portion 3 created on the one of the cooling tubes 2 adjacent the intermediate cooling tube 2 a on an inside of the “U” shaped configuration.
  • the depth h 2 of the helical portion 3 created on the intermediate cooling tube 2 a of the radiator is more than a depth h 3 of the helical portion 3 created on the one of the cooling tubes 2 adjacent the intermediate cooling tube 2 a on an outside of the “U” shaped configuration.
  • Each of the cooling tubes 2 , 2 a has a substantially constant diameter along its entire length.
  • the radiator according to the present invention provides a substantially uniform distribution of fluid in the cooling tubes 2 to optimize operation of the radiator without a drop in a pressure value in the radiator.
