HENRI STURM in PARIS.

Patented in the German Empire on May 16, 1906.

The invention relates to a device for the transfer of heat to gaseous or liquid ^ means in which the gas to be heated, water or the like. In fine and long beams is passed through the device. This device consists of elements, each of which in a known manner consists of several concentrically plugging into one another, with their walls

ίο including thin, helical channels Cylinders is put together. The novelty of such a known device is that the cylinders of each element on a single one in the upper part of the element and outside of the fire lying contact point interchangeably connected to each other and the upper ends of each cylinder are designed to be conical contact surfaces that by simply tightening one on the top exposed ends of the outer cylinder screwed on union nut the mutual concentric position of all cylinders secures.

Two embodiments of the subject matter of the invention are shown in the drawings. 1 and 2 each show a device in longitudinal section and FIGS. 3 and 4 show the corresponding top views.

Every element. consists in a known manner of several concentrically nested Pipe bodies 1, 2, 3, 4 with external thread to form fine channels 13, 14, 16. A Another fine channel 4 ″ is provided in the tube 4 by a threaded one Solid body 4 'formed.

By one provided with a metal insert 15 ' Flange 15 on tubular body 3, channels 16 and 13 are separated from one another.

In Fig. Ι the inner tube 4 runs into a conical extension 18 and in Fig. 2 the solid body 4 'in a conical extension 19 through which a tight seal is achieved. The body 4 'is also provided in FIG. 2 with a channel A' which is connected to an annular chamber 10 "by means of openings A".

In order to establish the connection between the individual pipes are now after of the invention, the tubes 1, 2, 4 provided with conical lugs 5, 6, 18 which according to Figure 1 are pressed against one another by a screwed-on union nut 9; this nut 9 sits on the external thread 9 'at the top of the pipe 1 and acts against one Flange 9 "on the pipe 4.

In the embodiment of FIG. 2, however, are. the individual parts with each other held in place by a threaded pin 9 '"provided in the lower part of the solid body 4', which is in an internal thread provided approach is screwed inside the outer tubular body I.

In both versions of the individual element, all threads of the line open 14 in an upper annular chamber 10, from which the heated. Liquid through one Nozzle 11 is derived.

. The pipe 4 ^{for the} introduction of gas, water or the like opens at the bottom at some distance from the bottom of the outer pipe body I. The pipe 3 serves to deflect the agent emerging from the bottom of the pipe 4 upwards into the channel 16 and opens at the top at a short distance from the .. upper closure wall in a chamber 10 ', from which the agent enters the channel 13 formed between the tubes 3 and 2; from the latter, the agent again strokes upwards in order to escape to the outside through the drainage pipe 11 after passing through the screw ducts.

The direction of the agent to be heated or cooled is indicated by arrows F.

With the relatively very long way of the medium flowing around very quickly any deposition of calcareous substances: prevented in the element.

Should the elements of the described arrangement be used as or for steam generators find, they are inserted into the flame immediately above the grate, causing an accelerated flow around and very rapid evaporation of the water flowing through is achieved. Through the The connecting points of the individual come from the peculiar design of the device Pipes not in contact with the fire.

The individual elements can be used independently or in groups and a number of such elements can be switched off or off, thereby in some cases at the required point a reinforcement of the performance take place and that as a result of the broadcast as well as by the Condensation, a steam line that causes considerable heat loss, is eliminated can.

Those that are circular, rectangular, perpendicular to one another or in oblique directions Pipe elements according to the invention can

as superheaters or as drying devices for steam in connection with existing steam generators and especially used where there is an additional service, such as at Warships, torpedo boats and the like in the shortest possible time without excessive stress the steam generator used for normal service should be available.

The assembly and disassembly of the parts of the individual element for the purpose of replacement and cleaning can be due to the peculiar design of the individual Element in the shortest possible time. To switch off an element during operation for replacement or cleaning purposes, the supply line and the discharge line are first shut off, whereupon the conical Connections, one of which connects the element to a tank or to the feed pump and their connect the other to a steam collector, unscrewed.

The element can be completely dismantled by loosening the nut 9 (Fig. 1) or the threaded full body 4 '(Fig. 2) with the following Removal of the individual tubular body achieved.

Claims (1)

Patent claim: Heat exchange device, the elements of which are made up of several concentric with one another stuck, enclosing thin, helical channels with their walls Cylinders are assembled, of which the outer cylinder is closed at its lower end, thereby characterized in that the cylinders (1, 2, 3, 4) of each element a single, in the upper part of the element and outside the area of the Fire's lying point of contact interchangeably connected to each other and the upper ends of each cylinder too conical contact surfaces (5, 6, 18) are designed, which by tightening a screwed onto the upper exposed end of the outer cylinder (1) Union nut (9) or by screwing down the middle solid body (19) are pressed against each other and then the mutual concentric position more velvety Secure cylinder. 1 sheet of drawings.
