We at first see Fig. 1 and Fig. 2, the tube bank of forming by many pipes 4 on the heat exchanger 2, and the axis XX of pipe is parallel to each other, and is arranged into two parallel row R1, R2.
Pipe passes many fins 6.Fin is vertical with the axis XX of pipe.
The end 8 of pipe 4 can be installed on the tube plate 10 hermetically, and 6 areas under control 12 of wearing of tube plate are generally rectangle, has many with should be in the hole 14 of pipe 4 ends 8 on it.The shape of the shape in hole and pipe end 8 adapts, and the direction of Kong Bianxiang fin 6 stretches and forms one section tubular flange 16.
As seeing among Fig. 1, tube plate 10 has a circumferential chimb 18, and this chimb forms that a circumferential groove 20 and some can depress turns over pin 22.
Be placed with an attaching parts 24 that constitutes by elastomeric material in tube plate and fin 6 opposite one sides.
This attaching parts is having compressible flange 28 by the centre portion 26 in the tube plate poling district 12, flange is pressed between the end 8 of the flange 16 of tube plate 10 and pipe 4 with any suitable method easily, such as available pressure pipe end 8 is pressed and expands into toroidal as flange 28 or with pipe end.
Have a chimb 30 to be placed in the groove 20 around the centre portion 26 of attaching parts 24, the periphery 32 of liquid storage box 34 is pressed in the top.
Pin on the tube plate 22 is depressed, limit 30 is compressed, to guarantee the sealing between liquid storage box 34 and the tube plate 10.
Liquid storage box 34 is basin shapes, and flange 32 constitutes the limit of its opening directions, and it is parallel that the base plate 36 relative with flange 32 and tube plate 10 are similar to, and base plate is connected with lateral sidewalls 40 by longitudinal side wall 38 with flange 32.
The structure of heat exchanger described above is that everybody is familiar with, and no longer describes in detail.
In addition, inhibiting device 42 is arranged on the liquid storage box 34, its restriction even forbid that pipe 4 ends 8 move in the hole 14 of tube plate 10, particularly moving with respect to the flange 28 of seal adaptor 24.Inhibiting device be positioned at pipe at least one end near.
As shown in Figure 1, inhibiting device is a boss 44 that stretches out from liquid storage box 34 inside, particularly as shown in FIG., stretch out from the inner face of base plate 36, reach on the end face 46 of end 8 of cooresponding pipe always, the axis XX near normal of end face and pipe, and certain distance is arranged apart from the base plate 36 of liquid storage box 34.
As shown in Figure 2, more particularly, the free end 48 of boss 44 is planes, and is approximate parallel with pipe end face 46, and is pressed on the end face 46, but do not influence flowing of liquid in the pipe.Boss be positioned at end 8 near, but depart from the axis XX of pipe 4, so that the major part of boss is outside the zone of pipe end face 46 restrictions.
In addition, as can clearerly seeing among Fig. 2, boss 44 can be replaced by the rib on the longitudinal side wall 38 of liquid storage box 38 50.Its free edge 48 is pressed on 8 cross sections 46, end of pipe 4.This rib that stretches out along whole or a part of sidewall is approximate parallel with the axis XX of pipe, and the free edge 52 that it is relative with sidewall 38 and the axis of pipe 4 maintain a certain distance.
Above-mentioned rib 50 also can stretch out from the lateral sidewalls 40 of liquid storage box 34, and is pressed on 8 cross sections 46, end of pipe 4.
As shown in Figure 2, for each array of pipes R1 of finned-tube bundle, R2 all can design a rib 50 and link to each other with pipe 4.
Because this by the inhibiting device that places near the corresponding pipe boss or rib to form, pipe can not produce mobile along its axis XX again, has so just guaranteed the end of pipe and the perfect sealing between the tube plate.
We see Fig. 3 and Fig. 4 now, and they have shown another example of the present invention, and the label above them is constant.
In this example, the boss 44 that stretches out from the base plate 36 of liquid storage box 34 between adjacent two tubes 4, this two tubes adhere to separately tube bank two rows (R1, R2).
As shown in Figure 4, the section of this boss is a rectangle.Two minor faces of free end rectangle at it are pressed in respectively on the cross section 46 of cooresponding two adjacent pipe end 8.
This boss 44 can be connected on the lateral sidewalls 40 of liquid storage box by connecting panel 54, and connecting panel 54 connects the vertical limit and the lateral sidewalls of boss.
Boss and connecting panel have been formed the inhibiting device that compresses two adjacent pipe.
Our Fig. 5 and Fig. 6 now, they have shown another example of the present invention.
As can be seen, end 8 usefulness of pipe 4 are contained in the mode of its flue that rises on the tube plate 10 hermetically on figure.
This pipe process that rises enlarges body 56 in the position that pipe 4 is connected with tube plate 10, constitutes first exit skirt 58, compresses the sealing shroud 28 between pipe end outer wall and tube plate flange 16.
Because this process, tube plate 10 is guaranteed with the sealing of pipe 4 ends 8, formed a shoulder 60 radially simultaneously between the body 56 and first exit skirt 58.
In addition, preferably do an exit skirt 62 again between first exit skirt and pipe end 8 cross sections 46, this second exit skirt bigger than first exit skirt diameter can be fixed on pipe 4 in the hole 14.
This second exit skirt 62 formed second shoulder 64 between first exit skirt and second exit skirt, and with first shoulder 60 distance of being separated by.
In such structure, be pressed in the inhibiting device 42 on pipe 4 ends 8, can be pressed on the shoulder 60 of first exit skirt 58, also can be pressed on the shoulder 64 of second exit skirt 62.
Therefore boss 44 should be designed to stretch form down from the base plate 36 of liquid storage box, its free end 48 insertion first exit skirt 58 or second exit skirts 62, and be pressed on the corresponding shoulder.
Show that as Fig. 5 the free end 48 of boss 44 is pressed on second shoulder 64 of second exit skirt 62, and as shown in Figure 6, its section is similar to the base portion 66 of rectangle by one and forms at the thicker targeting part 68 at its two ends.Targeting part has a columniform outside face 70, and its diameter is consistent with cooresponding bell-mouthed diameter, is exit skirt 62 here.Two vertical walls 72 link to each other with the main body 66 of boss 44.
Distance A between the face of cylinder 70 should be approximate identical with corresponding flared end diameter, is exit skirt 62 here.Two vertical walls 72 link to each other with the main body 66 of boss 44.
Fig. 6 shows another kind of recommend method, tube end ovalize exit skirt, and the distance A on the face of cylinder is approximately equal to oval bell-mouthed minor axis.Free end 48 has an inclined-plane 74, and the inclined-plane of the shoulder that is compressed with it is consistent.The thickness B of main body 66 should be enough little, so that reduce the influence to flow of liquid in the pipe as far as possible.
The present invention is not limited to the example of above introduction, also comprises all change examples.
Especially, the inhibiting device in the above-mentioned example be with a pipe and (or) be in two adjacent pipes of two different rows.They also can be used for many pipes, and whenever will have all has an inhibiting device on the pipe, and also can (or) be used for two of delegation adjacent pipes.
