ffixma Industrie-Companie Kleine-wefers Konstruktions »und Hand el sge rope team from B. IDrefeld «Helanchthonstrasse 5 * associated with TTg heat exchangers with connected through the drilling BSd en *

The aim of all heat exchanger designs is to provide for oil individual bores largely independent expansion options that allow the bore to be lengthened compared to the cold state without it tearing off or the subsequent changes in length sax leaks.

In order to achieve this, it is proposed for heat exchangers according to the price increase that one of the two floors, in which the borehole is attached, be made of several layers of sheet metal lying on top of each other, so that this floor can bulge and still be in its entirety enough pressure and corrosion resistance. The bores are firmly embedded in a known manner in a rigid floor opposite the elastic floor; eiBEt »

In the case of more practical execution, a 4-way elastic base can be used . the. Hoehgebördelt drilling ends so that msn press the flanging onto the drill with a pushed-over bing. can. On the one hand, the resilient floor provides the drill with a bead or the like. provided in order to lay ÖexL soil in this way.

When the heat-emitting medium flows into the boring itself, becomes the elastic floor between the rigid and the "^ orestzboden attached and provided with the prefabricated floor. The effect in this case is the same as in an execution vso öer elastic base arranged at the outer drilling end will.

There are several exemplary embodiments on the drawing of heat exchangers according to the furnace, and ZTiar shows:

Pig. 1 schematically the section through an exchanger » Fig. 2 shows the formation of a drilling end in section. Fig. 3 shows another embodiment in section and 4 shows a further modification of the elastic base.

Uaen * 'ig. 1, the Böhrenvs arm exchanger consists of an elastic base 1 and a rigid base 2, into which the tubes 3 are inserted. " 33er elastic bottom 1 of according to the Äeuerujog of several layers of thin superimposed sheets consists, is at SSEx heating against the various Xängenänöerungen öex Drill 3 little resistance, so that si "can not sbreissen by Yiermedehnung and thus maintaining the seal. Protected from excessive temperature and thermal stresses by a door set floor 4 τ, 1x6 öer elastic floor 1,

According to FIG. 2, the elastic drill base 5 can be attached to the ear ends 6 by providing the base 5 on each drill with a bead 7 so that it can be covered with a welding rod. attached to ö.sb Eoiir 6 v? ird. This attachment can be done in a simple manner through

take place, vcobei the H ohr ft anö at the drilling end is tapered and to the strength öee? eissend en ^ lechee must be adapted to a large extent in order to avoid overheating en in the thin - ⁰ IeCh 5. .A sing 6 is pushed onto the flange 7, which removes the inheritance effect in <3 shots iron seam 5, which can occur with expansion of the drill 6 and the curvature of the bottom.

To further relieve the Schsveissnaht 9 you can Drilling in the in Pig. 2 shown way to the outside Place the Sing B and then drill 6 with a bead 10 ". In order to allow the bottom 5 to arch, the Bing 8 designed so that it only rests directly on the drill 6 on the floor 5.

. 3 shows an installation possibility of drilling 6 in a thin elastic floor 5, the weld 9 between floor 5 and drilling 6 is relieved by widening the drilling end 6 and by beads 10 _f which lie directly on the floor 5. Between the bottom 5 and the bore 6 ε-η derBöröelung by means of resistance, welding, a tack lens 13 or a non-welded seam can be attached. In this version, too, the base 5 is protected by an attachment base 11.

If the medium that gives the sound flows into the bores, then the door base 11 and not the elastic ear bores 5 must be provided for the outer boring, so a version according to 4 can be chosen * The protection of the thin sheet metal ” The bottom 20 is covered by the torsion body 21, in which the drill 18 is arranged in an isbest sealing ring 22 or the like, or in a yoke 23, can slide in the event of thermal expansion. Yfie can be seen from the drawing, the elastic drill floor should be used here

be shouted with the Vcr setzbodeji 21. The connection between the one-piece attachment base 21 and the elastic sheet metal base 20 can be made by means of an intermediate ring 24, creating a wall thickness transition between the gusts 20 and 21, which at the same time allows the elastic base 20 to bend at the connection point. Nsirel achieved this by a thin family 25 sn the intermediate ring 24 "with the diameter 25 of the lipped this elastically * bottom 20 corresponds etvsa uer strength.
