Abstract

PURPOSE:To obtain the heat exchanger, eliminating an useless gap which is not contributing heat radiation, small in size and having a good heat radiating property, by a method wherein the end of a fluid tube is connected to a header plate with the elliptical section itself. CONSTITUTION:The end of the fluid tube 13, provided with a multitude of heat dissipating fins 14 in parallel and having the elliptical section, is inserted into the collared opening 11a of the header plate 11, the whole of the end of the tube is expanded into an elliptical shape at the inserting part, the collared opening 12a of a gasket 12 is pressed into and interposed inbetween the expanded part 13a and the internal surface of the collared opening 11a of the header plate 11 to attach the tube to the header plate 11 air-tightly, and the long arc part, symmetrical to the long axis of the ellipse at the opening end of the expanded part 13a, is expanded further to obtain a retainer 13b, holding the tube so as to prevent the slip-off thereof from the header plate 11 by a force applied to F- direction by pressure fluid in the tube. According to this method, the useless part, in which the elliptical section is turning into a circular section gradually, may be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a fluid tank with one 111! An aperture opening is provided in the hengoo grate that forms the I wall, and a fluid Ih° with heat dissipation fins arranged side by side is added to this opening in the divine direction and flows into the fluid pipe/passing through the a body and the fin surface. A type of heat exchanger that performs a hot exchange between the primary fluid and the primary fluid, for use in the entire scooping system, or for turning off the engine tS. This glazed heat exchanger [the curved cedar shape of the fluid pipe, which is currently in use in large numbers, is B shape, and this shape of flow f4-
Although it is easy to manufacture a heat exchanger that uses intelligence, there is a problem that the pressure loss of the air is large.
In order to reduce air pressure loss, a heat exchanger in which the cross-sectional shape of the fluid pipe is oval is already well known.

A gasket is placed on the pressure 1illI surface where tX'+% pressure acts and the inner peripheral surface of the collared opening +11. The end of the fluid tube +41 is inserted through it, and the entire end of the fluid tube +41 is enlarged at this insertion part, and a 00 mark is formed between the inner surface of the collared opening (1 m) of the hengoo plate (1). The collar of Gas Gund +21 is open (2 &
FC is sealed, and the entire length of the fluid pipe + 41 is enlarged to the length, and a gasket (2J collared opening (2a

The hengoo plate il+ is held so that it does not come off from the fluid pipe (4) due to the force acting in the direction.

By the way, when using the conventional θIJ notation and one exchanger, the end of fluid '1ii (4j) is
In order to connect C, the base of the fluid' et al. (0 is created, and this part is a random gap that does not affect the heat radiation.The only way to do this is to install a heat radiation fin and unpack it.) There was also a small Zen stand for heat dissipation and pressure relief.

This invention solves the above drawbacks and improves and eliminates them.% 17

Next, the assembly procedure of the above embodiment will be explained. First, push the fluid pipe α, 3jtl- through the oval collared extension hole (14a) of the required number of heat dissipation fins (14I).
Using an optional elliptical expansion jig (not shown) for the fluid pipe I, expand the fluid pipe 4 using this tool W, and attach the radiation fin α to the fluid pipe. )! If you add ff1a, you will get a heat exchanger core made of fluid pipes with many radiation fins arranged in parallel! ; make it happen. This yarn-exchanger core (Hengoo gray) (+1 is placed and a white clover hengoo plate (gasket is placed on the pressure surface where the pressurizing body of IIJ acts and the inner space of the collared opening (1la)) u4'
Temporarily, connect the end of the fluid pipe 04 to the collared opening (l1m) of the heng grate (11), and attach the end of the fluid pipe 04 to the collared opening (l1m) of the heng grate (11).
Optional carvings with an oval shape throughout (not shown)
As shown in Figures 2 and 2, it expanded into an elliptical shape, and a gas gap (1 m) was formed between the bulge 141j (13 m) and one river of the collared opening (l1 m) of the Hengu plate (1υ).
2J collared opening (12m)? ]: The fluid tube is inserted into the fluid tube with pressure and pressure.

Next, insert an arbitrary punch (not shown) with an exit capital on the symmetrical inner arc circumference of the elliptical cylinder into the enlarged part (13&) of the fluid pipe O:1. The elongated arc portion symmetrical to the long axis of the ellipse at the opening end of the ampullae (13&) of the fluid ejecting tube is expanded to its full length using a punch to form a pull-out stop portion (13b). Accordingly, it is possible to assemble the heat exchanger shown in FIGS. 3 to 5.

According to the above-mentioned heat exchanger of this invention, the end of the fluid pipe 04 is elliptical so that viscosity can be achieved. The deformable part (wasteful gap for odor is eliminated), and the size of the part can be reduced.

If the core is the same size as the core for the exchanger, the heat dissipation fin (14J) can be increased to improve the heat dissipation. 13b) as the enlarged part (131L) of the fluid pipe l131 in the same way as the conventional fluid pipe itl.
When attempting to shape the entire circumference of the fluid pipe 04, stress concentrates on the part A of the enlarged part (13a) shown in FIG.
There is a risk of cracking, etc., and the size is 8jS (13&)
It is 1 distance to form a pull-out stop part in the A part. Furthermore, the pull-out stopper (13b) formed in the enlarged part (13m) of flow f+ and evacuation a4 is not limited to the shape shown in Fig. 5, and examples thereof are shown in Fig. 2 and Fig. 1O. It may be formed into a shape.

Fig. 77 shows an example in which this pseudo-elliptical shape, for example, a streamlined fluid pipe, is applied to a heat exchanger for transporting water. The large 1ll IS (13a') is enlarged to form an elongated arc symmetrical to its long axis to form a pull-out stop (+ on 13), achieving the same effect as the iij ribbon. can.
