  • the tube-side end plate 21 is constituted of a flat plate with its edges bent toward the pipe-side tank member to form a fitting frame 25, into which the pipe-side tank member 20 is fitted.

  • the heat exchanger described above since it is possible to mount the tube elements 1 after setting their lengths arbitrarily by cutting, a heat exchanger with specific variations in the length of the tube elements 1 can be constituted with relative ease and at low cost.
  • the lengths of the tube elements 1 can be varied simply by changing the length of a single type of tube element formed in a single metal die and it becomes possible to produce a heat exchanger with tube elements of differing lengths (different variations) on a single automated assembly production line.
  • each tube element 1 is brazed while fitted into a tube fitting notch 33 of the partitioning plate 22 inside the tank 5, a fillet is formed on the tank at the time of brazing the tube-side end plate 21 of the tank 5 and the tube elements 1. Consequently, there is no danger of the brazing material being drawn away to the fins 2, and thus, brazing material shortage is prevented, ensuring good brazing.
  • FIGS. 5 and 6 Note that components with identical structures to those in the first embodiment are assigned the same reference numbers and their explanation is omitted here.
  • the difference between the heat exchanger in the second embodiment according to the present invention and the one in the first embodiment described earlier is that, as shown in FIG. 5, a plurality of indented portions for cutting 41 are provided at appropriate locations toward the outside in the direction of the width of a tube element 40.
  • the other structural features are identical to those in the heat exchanger in the first embodiment.
  • each tube element 40 at least one indented portion for cutting 41, which is indented from the outside of the tube to the inside is provided along the length of the tube whose cross section shape is formed consistent from the intake / outlet ports 16a and 16a formed at the intake / outlet portion 16 to the flow path U-turn area 17, and the length of the tube element 40 can be set arbitrarily by cutting at a given indented portion for cutting 41 to a specific length (for instance, L1, L2, L3 or L4 in the figure).
  • the shape of the cross section of the front ends of the intake / outlet ports 16 and 16 remains unchanged after the tube element 40 is cut at the specific position mentioned above, and also, under the indented portion for cutting 41, a tank contact portion 42 for positioning the tube element 40 through its contact with the tube-side end plate 21 of the tank 5 is formed after the cut.
  • the method of assembling the heat exchanger does not change because of the cutting in any way whatsoever (see FIG. 6).
  • tube elements 40 that are inserted in the tube element insertion holes 27 of the tank 5 are brazed with their tube partitioning portions 18 fitted into the tube fitting notches 33 of the partitioning plate 22, as in the case of the heat exchanger in the first embodiment (see FIG. 6).
  • the heat exchanger described above since it is possible to mount the tube elements 40 after setting their lengths at arbitrary lengths by cutting them at a specific position, a heat exchanger with a number of variations in the length of the tube elements 40 can be constituted with relative ease and at low cost.
  • the lengths of the tube elements 40 can be varied simply by changing the length of a single type of tube element formed in a single metal die and it becomes possible to produce a heat exchanger with differing lengths of tube elements (different variations) on a single automated assembly production line.
  • the shoulder of the remaining portion of the indented portion for cutting 41 that has been cut functions as a tank contact portion 42 which performs positioning by placing the tube element 40 in contact with the tube-side end plate 21 of the tank 5.
  • the tube elements 40 do not hit the partitioning plate 22 and consequently, no gap is formed between the partitioning plate 22 and the tube-side end plate 21 during assembly, which in turn prevents leak inside the tank 5.
  • a protrusion 36 which fits into the tube partitioning portion 18, is formed on both sides of each tube element insertion hole 27 at approximately the middle thereof.
  • the shape of the tube element insertion hole 27 is formed identical to the shape of the cross section of the tube element 1. Because the protrusions 36 are provided, no protrusion is formed at the sides of the tube fitting notches 33 of the partitioning plate 22 and, therefore, only the tube fitting notches 33 are formed, and the shape of the partitioning plate 22 is simplified.
  • the other features have identical structures to those in the first embodiment, are assigned the same reference numbers and their explanation is omitted here.
  • the lengths can be achieved by simply changing the length of a single type of tube element formed in a single metal die and it becomes possible to produce a heat exchanger with differing lengths of tube elements (different variations) on a single automated assembly production line.
  • each tube element is brazed while fitted into a tube fitting notch of the partitioning plate inside the tank, a fillet is formed on the tank at the time of brazing the tube-side end plate of the tank and the tube elements. Consequently, there is no danger of the brazing material being drawn away to the fins, and a brazing material shortage is thus prevented, ensuring good brazing.
  • the intake / outlet portion of the tube element is divided into an intake side and an outlet side by the partitioning plate of the tank, no leak of heat exchanging medium occurs.
