Heat exchanger

The invention relates to heat exchangers between at least two fluids ». In particular concerns the invention heat exchangers for at least two media. In particular, the invention is concerned with heat exchangers with at least two trees enveloping one another in spirals, the heat exchanger has a substantially cylindrical shape.

According to the known state of (Pechnik, Proposed heat exchangers of this type in which at least one of the media or fluids flows in (or emerges from) its barely over a store arranged in the middle of the turns to around the circumference to leave (or to enter). another storage device arranged outside the windings. In order to be able to absorb the pressures of the media, it is necessary either to have an external steam or

To use vapor space that holds the spiral bundle, it should be noted that the fluid = passage through the Briidenrauia to a considerable Weakening leads or making the spaces or chambers from a fairly thick sheet of metal, so that last turn, which is bent in an expedient manner and welded to itself, the same Result with external reinforcements, achieved »

The first solution leads to considerable and almost unavoidable difficulties in the practical implementation of the tight connection between the heat exchanger surface and the external storage tank above the vapor chamber, these organs of considerably different thickness and dissimilar thermal changes being exposed to considerable stresses in the the most difficult places. The second solution is difficult and not very economical. None of the! Solutions is suitable for increased pressures. Also, it is observed that the cost price of Wäraieaustauscher scroll type makes no means suited the other Wärmeaus'bauscfcerbauarten _t example Mehrröhronbauarten to displace "

The aim of the inventive heat exchanger in which a share price between half and a third of the usual heat exchangers is achieved, it is theirs outside of the steam or vapor room arranged memory, as mentioned above, to be omitted by either the heat exchange walls winding around the inlet and outlet reservoirs of the same fluid by having the passage of the dsm Fluids through, laterally recessed in the flanks of the spiral body (for larger quantities)

provides openings. This eliminates all of the above-mentioned disadvantages in the other two cases. In this way, a spiral bundle is produced independently of the external vapor area, which is intended to absorb the pressures; simple guide devices are also provided according to the invention in order to force a complicated path on at least one medium. The fact that the bundle has been separated from the vapor space is a significant advantage that enables very thin heat exchanger walls to be used, even at high pressures, by using two central reservoirs as a framework, which is designed to hold the thrust of the against the Center-facing interior Λ

pressures as well as an outer ring or boiler shell shot, which is intended to withstand the Thrust of internal pressures directed against the circumference to record. It is advantageous to use smocks to create a punch between the walls, which help supposed to lead the media. Thus, according to a preferred embodiment of the invention, the heat exchangers are spaced apart from one another by cherwandungen Hold projections which are intended to guide the medium either directly or for positioning Contribute to the partition walls by having four other functions to keep the poles at a distance. keep the exchange surface (by extending the Metals) to increase the rigidity of the sheet, which makes it possible to increase its thickness reduce and generate l \ irbulence, which is intended are to increase the heat exchange coefficient.

Another aim of the invention is that it becomes possible to use these exchangers to treat fluids whose inlet temperatures are extremely

are different, what is possible with a concentric arrangement of the central memory, whereby absolutely any stress due to thermal expansion disappears and the device easily turns can be dismantled

According to another embodiment of the invention, a further additional film or an additional sheet is used as a spacer, this film at the same time "serving to a considerable extent with this. To the exchange surface in contact with the medium enlarge. This is how the boiler and air-to-air cooler are manufactured.

From the advantages mentioned, it follows * that the heat exchanger according to the invention is an exceptional one have favorable thermal efficiency, are very compact, with two to three times less material can be manufactured and mass production is easily made possible, since they can be used with almost all Adjust heat exchanger problems. Your manufacturing price is a third or half of that of the known heat exchangers with higher performance at the same time.
