Definitions
- the invention relates to a heat exchanger wound in a spiral, where the fluids arrive, circulate and open in countercurrent, in the direction of the winding axis.
- recuperators for gas turbines Indeed, they must be compact, high efficiency, inexpensive and reliable. Efficiency and compactness can be obtained by using the concept of primary surface, with channels of small hydraulic diameter and by circulating the two counter-current fluids.
- the cost price will be low if the exchanger consists of the assembly of a small number of printed elements and continuously wound to form a roll.
- the pressure drops will be reduced if the passage sections offered to the two fluids are sufficient: this is obtained by circulating the fluids axially and not tangentially in a spiral exchanger.
- the exchangers are subjected to high thermal loads and thermal shocks resulting from transient variations in the operation of the turbine. Reliability is linked to resistance to thermal shock.
- Heat exchangers consisting of a winding of a pair of sheets, between which the fluids pass countercurrently, in the axial direction of the roll thus formed, are known: see for example a recent patent (1995) from the company Rolls- Royce, where the flux is distributed by cutouts made in the sheet and welded in pairs at the time of winding.
- the invention as defined in claim 1 relates to a heat exchanger formed by winding a pair of sheets in which the fluids circulate in opposite directions in the direction of the axis of the winding and arrive and open on the faces opposite of the cylindrical roller formed by the winding of the sheets.
- This avoids creating distribution cutouts inside the exchanger, which eliminates both stress concentrations, welding problems, inspection and repair of these flanges embedded in the mass of the exchanger. This results in greater freedom in the choice of dimensions and shapes of the distributor-collectors, since they are external to the exchanger itself.
- Figure 1 is a perspective view of the exchanger showing the flow of fluids (air and gas) entering and leaving the exchanger.
- FIG. 2 is a partial view of the air and gas distribution openings on one of the faces of the exchanger.
- Figure 3 shows an air supply sector capped with its distribution scoop, in exploded view.
- Figure 4 shows one of the two sheets, before winding, in partial plan view.
- Figure 5 shows the other sheet, before winding, in partial plan view.
- FIG. 6 represents a pair of sheets placed side by side in the exchanger, in radial section.
- FIG. 7 shows the path of air and gas, between a pair of sheets, from one side of the exchanger to the other, in partial view.
- the exchanger consists of a core 1 to which are attached scoops 8 for supplying and discharging air 2, FIGS. 1 and 3.
- the air penetrates by angular sectors 5 regularly spaced and alternating with angular sectors 6 for the outlet of the gases.
- the core consists of a winding of a pair of sheets a and b around a z axis, figure 1
- the sheet a is wrinkled longitudinally. that is to say along the winding axis z, while the sheet b is transversely, that is to say along the tangential winding direction ( Figures 4 and 5).
- the sheet a has three axial zones of wrinkles: zones II and IV near the edges and zone III central (figure 4).
- the sheet b is wrinkled on these same three zones and also comprises, on the zones I and V of entry-exit, flanges 7 offset alternately to form the openings of arrival-exit of the fluids (FIGS. 5 and 2) .
- the offset edges of b come against the edge of a and vice versa, during winding. They are definitively brazed together, once the core has been wound up ( Figure 2). The alternative offset of the edges of b must be done during winding and in synchronization with it. It is indeed necessary that the gills thus formed are of increasing length at each winding turn and in angular phase to form very regular angular sectors.
- the scoops 8 are then brazed on the faces of the core 1, with their edges 9 brazed on the edges 10 of the angular sectors, as indicated in FIG. 3.
- the sum of the heights of the wrinkles of a and b is constant over all the zones; it is worth the offset of b on the zones I and V and allows the winding without radial deformation of the pair ab, because it is of constant thickness equivalent to the sum of the heights of the wrinkles of a and b, as illustrated by the figure 6.
- zones II and IV. the wrinkles of a and b have comparable heights: being perpendicular and in contact with their crests, they allow the passage of air and gas in both directions, axial and tangential: these zones are zones of distribution of the flow from the entrance sectors towards zone III; these are cross-flow zones, as indicated in FIG. 7
- zone III the flows are essentially parallel and opposite; that is to say against the current (Figure 7), because the tangential wrinkles of b are minimal and those of a, axial, are large ( Figure 6).
- This type of exchanger can also be produced by replacing the wrinkles printed in relief by fins of the same height, filling with flat sheets.
