あつた。 By the way, in the conventional heat exchanger, in order to reliably connect the ends of the fluid pipes 4 to the header plate 1, the ends of the fluid pipes 4 are deformed from an elliptical cross-sectional shape to a circular cross-sectional shape. Ta. For this reason, a portion l that gradually deforms from an oval shape to a circular shape is created, and this portion l becomes a wasted gap that does not contribute to heat radiation, and the overall dimension increases by this dimension, or the mounting area of the heat radiation fin decreases, resulting in poor heat radiation performance. There were some inconveniences, such as making things worse.

てを終えることができる。 Next, the assembly procedure of the above embodiment will be explained. First of all,
The fluid pipe 13 is inserted into the oval collared insertion hole 14a of the heat dissipation fin 14 stacked in the required number of layers, and then an arbitrary oval pipe expansion jig (not shown) is inserted into the fluid pipe 13. With this jig, the fluid pipe 13
is expanded and the heat radiation fins 14 are securely fixed in contact with the fluid pipes 13 to form a core for a heat exchanger in which a large number of heat radiation fins 14 are arranged in parallel on the fluid pipes 14. Header plates 11 are disposed on both sides of the heat exchanger core, and gaskets 12 are fully bonded to the pressure surface of the header plate 11 on which the pressurizing body acts and the inner surface of the collared opening 11a. Thereafter, the end of the fluid pipe 13 is inserted into the collared opening 11a of the header plate 11, and the entire end of the fluid pipe 13 at this insertion portion is cut with an arbitrary elliptical expansion jig (not shown). , as shown in FIGS. 6 and 7, an enlarged portion 13a having a larger oval cross section is formed, and the collar of the gasket 12 is inserted between this enlarged portion 13a and the inner surface of the collared opening 11a of the header plate 11. The fluid pipe 13 is hermetically inserted into the header plate 11 by compressing the opening 12a. Next, the enlarged portion 13 of the fluid pipe 13
An arbitrary punch (not shown) having a protrusion on the circumferential surface of an elongated arc symmetrical to the long axis of the elliptical cylinder is inserted into a, and this punch punches the elliptical shape of the opening end of the enlarged part 13a of the fluid pipe 13. The elongated arc portion symmetrical about the long axis is further expanded outward to form a retaining portion 13b as shown in FIGS. 3-5. With this, the assembly of the heat exchanger can be completed.
この発明の上記熱交換器によれば、流体管１３

ができる。 According to the heat exchanger of the present invention, the fluid pipe 13
Since the end portion of the header plate 11 can be connected to the header plate 11 as long as it is oval, there is no unnecessary gap in the portion l that gradually deforms from an oval shape to a circular shape as in the conventional case.
The overall size can be reduced by that amount. Alternatively, if the heat exchanger cores have the same dimensions, the mounting area of the heat radiation fins 14 can be increased, and heat radiation performance can be improved.

Stress is concentrated in the fluid pipe 1
3 may be cracked, etc., and it is difficult to form a retaining portion at portion A of the enlarged portion 13a. Further, the retaining portion 13b formed in the enlarged portion 13a of the fluid pipe 13 is not limited to the shape shown in FIG. 5, but may be formed in the shape shown in FIGS. 9 and 10, for example.

An elongated arc portion symmetrical to the long axis of the enlarged portion 13a' is expanded to form a retaining portion 13b', and the same effect as described above can be obtained.

利である。 As explained above, the present invention includes: a header plate having a plurality of elliptical collared openings; a gasket having a plurality of elliptical collared openings facing the collared openings of the header plate;
It consists of a plurality of fluid pipes each having a plurality of elliptical cross-sectional shapes, each having a plurality of heat dissipation fins arranged side by side and whose ends are inserted into the collared opening of the header plate, and a fluid tank fitted into the header plate. , a gasket is disposed in close contact with the entire surface of the header plate on the pressure surface on which fluid pressure acts and the inner peripheral surface of the collared opening, and the end of the fluid pipe is inserted into the collared opening of the header plate. In this insertion part, the entire end of the fluid pipe is expanded into an elliptical shape, and the collared opening of the gasket is compressed and interposed between the inner surface of the collared opening of the header plate and the fluid pipe is hermetically inserted. , because the pipe wall corresponding to the long arc portion of the elliptical cross section at the open end of the fluid pipe is partially pressed radially outward to expand and prevent the header plate from slipping out between the fluid pipe. Therefore, it is possible to provide a heat exchanger that can eliminate wasteful gaps that do not contribute to heat radiation, has a small overall size, and has improved heat radiation performance. Moreover, according to this invention, when attaching the fluid pipe having an oval cross section to the header plate,
Instead of first transforming the cross section into a circular cross section and then expanding it to a larger diameter circular cross section as in the past, we decided to expand the oval shape and expand the long arc portion of the oval cross section. Since the pipe is designed to prevent it from coming off, there is no risk of damage to the small diameter part, which has an oval cross section, if excessive force is applied to the fluid pipe, and this also improves work efficiency. It's advantageous.
