FIG. 1 is an exploded perspective view of a heat exchanger assembly according to a first embodiment of the present invention. The heat exchanger assembly 100 is installed in an engine room of an automobile, and includes a first heat exchanger 10 that is an intercooler for turbo, a second heat exchanger 20 that is a radiator for cooling water, and a car cooler. And a third heat exchanger 30 which is a condenser.

  As shown, the core 13 of the first heat exchanger 10 is disposed between the two tanks 11 and 12. Similarly, the cores 23 and 33 of the second heat exchanger 20 and the third heat exchanger 30 are also disposed between the two tanks 21 and 22 and the tanks 31 and 32, respectively.

  FIG. 2 is a longitudinal sectional view of the first heat exchanger shown in FIG. As shown in FIG. 2, a plurality of tubes 16 that connect the tank 11 and the tank 12 are disposed inside the core 13 of the first heat exchanger 10. A fin 15 is provided between each of the plurality of tubes 16 so as to contact the tubes 16. For simplification of the drawing, only a single fin 15 and tube 16 are shown in FIG.

  Furthermore, as can be seen from FIG. 2, an inner fin 18 that promotes a cooling action is provided inside each tube 16 of the first heat exchanger 10 so as to contact the inner wall of the tube 16. As can be seen from FIG. 2, the orientation of the inner fins 18 is perpendicular to the orientation of the fins 15. Instead of the inner fin 18 shown in FIG. 2, an inner pillar (not shown) may be disposed in the tube 16. These inner fins 18 or inner pillars serve to support the tube 16 from the inside, and as a result, increase the robustness of the first heat exchanger 10.

  Although not shown in the drawing, the core 23 of the second heat exchanger 20 and the core 33 of the third heat exchanger 30 have substantially the same configuration as the core 13 of the first heat exchanger 10, and are shown in FIG. It is sufficient to change the tenth digit of “2” or “3”. Therefore, the description of the core 23 of the second heat exchanger 20 and the core 33 of the third heat exchanger 30 is omitted. However, in the case of the core 23 of the second heat exchanger 20, the core 13 of the first heat exchanger 10 and the second heat exchanger 20 of the second heat exchanger 20 are not provided in that no inner fins or inner pillars are disposed in the tube 26. Different from the core 23.

  Referring again to FIG. 1, the horizontal bracket 62 extends from the top of the tanks 11, 12 of the first heat exchanger 10 so as to be separated from the core 13. Similarly, horizontal brackets 61 extend perpendicularly from the tops of the tanks 11 and 12 to the length of the core 13, respectively. As shown in the figure, holes are formed in the brackets 61 and 62. Two similar holes 63 are also formed on the top surface of the core 13 of the first heat exchanger 10. Although not shown in the drawing, it is assumed that the holes and the holes 63 of the horizontal bracket 62 are also formed on the bottom surface side of the first heat exchanger 10 in the same manner.

  The bracket 61 and the bracket 62 may be integrated with each other, or may be integrally formed with the tanks 11 and 12, respectively. Further, holes 75 perpendicular to the length of the core 13 are formed below the tanks 11 and 12 of the first heat exchanger 10.

  On the other hand, holes 71 corresponding to the holes of the bracket 61 of the first heat exchanger 10 are also formed on the top surfaces of the tanks 21 and 22 of the second heat exchanger 20 that is a radiator. In addition, a vertically oriented bracket 65 extends below the tanks 21 and 22 of the second heat exchanger 20 so as to be separated from the core 23. These brackets 65 may be formed integrally with the tanks 21 and 22, respectively. As shown in the drawing, these brackets 65 are also formed with holes similar to those described above.

  Furthermore, the protrusion 34 extends in the vertical direction from the top and bottom surfaces of the tank 31 of the third heat exchanger 30 that is a condenser for the car cooler and from the top and bottom surfaces of the edges of the core 33. Instead of extending from the edge top surface and bottom surface of the core 33, the protrusion 34 may extend from the top surface and bottom surface of the tank 32.

  By the way, in FIG. 1, the upper side connection member 50A and the lower side connection member 50B which are used to connect the first heat exchanger 10 and the third heat exchanger 30 are shown. Since these connecting members 50A and 50B have similar shapes, only the upper connecting member 50A will be described below.

  As can be seen from FIG. 1, the length of the upper connecting member 50 </ b> A that is a plate-like metal member is smaller than half the length of the cores 13 and 33 of the first heat exchanger 10 and the third heat exchanger 30. The width of the upper connecting member 50A is sufficiently long to connect the first heat exchanger 10 and the third heat exchanger 30 with a desired gap provided. Near the center of the upper connecting member 50A, a mount pin portion 55 extending perpendicularly to the upper connecting member 50A is attached. The mount pin portion serves to attach the entire heat exchanger assembly 100 to an engine room of an automobile via a rubber mount or the like. Although not shown in FIG. 1 and the like, the first heat exchanger 10 (intercooler) may be provided with another mount pin member for attaching the entire heat exchanger assembly 100 to an automobile engine room or the like.

  As shown in the drawing, three holes 52, 53, and 54 are formed in the upper connecting member 50A. Two of these three holes 52 and 53 are arranged in parallel to the length direction of the upper connecting member 50A. The distance between the holes 52 and 53 is substantially equal to the distance between the hole of the bracket 62 and the hole 63 described above. The remaining holes 54 are formed at positions shifted in the width direction of the upper connecting member 50 </ b> A from the line segment connecting the two holes 52 and 53.

As a result, the second heat exchanger 20 is attached to the first heat exchanger 10.

  As shown in FIGS. 1 and 3, it is preferable to use a screw 70 between a bracket 61 of the first heat exchanger 10 and the second heat exchanger 20 via a bush, for example, a rubber bush 80. Similarly, the lower screw 70 is preferably used via a rubber bush 80 between the bracket 65 of the second heat exchanger 20 and the first heat exchanger 10. Usually, since the material constituting the first heat exchanger 10 and the material constituting the second heat exchanger 20 are different, the thermal expansion coefficient and the operating temperature range of these materials are also different. When the assembly 100 is used, a difference in thermal expansion may occur between the first heat exchanger 10 and the second heat exchanger 20 and the tubes of the first heat exchanger 10 or the second heat exchanger 20 may be damaged. is there. However, in the present invention, since the rubber bush 80 absorbs such a thermal expansion difference, the tube of the first heat exchanger 10 or the second heat exchanger 20 is damaged when the heat exchanger assembly 100 is used. Can be avoided. Such a rubber bush 80 can also serve to absorb vibrations and mounting tolerances between the first heat exchanger 10 and the second heat exchanger 20.

Therefore, in the present invention, it can be said that the first heat exchanger 10 of the heat exchanger assembly 100 supports the entire heat exchanger assembly 100 in the engine room or the like via the mount pin portion 55. That is, the load of the second heat exchanger 20 and the third heat exchanger 30 is applied to the first heat exchanger 10.

  In this regard, in the present invention, the first heat exchanger 10 is an intercooler, and the inner fin 18 or the inner pillar is formed in the tube 16, so that other heat not provided with such an inner fin 18 or the like is provided. It is more rigid and robust than the exchanger 20. Therefore, even when the loads of the heat exchanger 20 and the third heat exchanger 30 are concentrated on the first heat exchanger 10, the heat exchanger assembly 100 is provided because the first heat exchanger 10 is robust. For example, damage to the tube netting can be prevented. As a result, the original functions of the heat exchangers 10, 20, and 30 of the heat exchanger assembly 100 can be maintained, and the positions of the mount pin portions 55 of the connecting members 50A and 50B can be arbitrarily set. The degree of freedom of mounting in 100 engine rooms increases.
