near nxcmena Application and October 21, 1924, Serial a... 745,023, and in France October so, 1923.
enables an exchange of heat to be-obtained which supplements that effected by means of.
the apparatus. This object isaccomplished by means of the hereinafter described device, which is characterized by a rotating member shaped and actuated in such a' way that its surface is bathed simultaneously in ally the fluids, by penetrating into their conduits though slits which it keeps obstructed the whole time.
' In the accompanying diagrammatic drawings, Figure 1 represents a sectional elevation on the line 1-1, Figure 3 of a simple type of air heater, which is given by way of example, Figure 2 is a sectional side elevation of the device shown in Figure 1, and 80 Figure 3 is a sectional plan on the line 3-3, Figure 1. -Figures 4 and 5' show, in thesame positions as in Figures 1 and 2, a modification of the wall which is common to the conduits.
Figures 6 and 7 are similar views of another modification of said wall.
In the embodiment shown in Fi ures 1,
2 and 3, the heat transmitting mem er is a rotating body and is composed of plain discs h threaded on a shaft 7 supported by bearings g. Two conduits, a for cold air and b for exhaust gases, are of rectangular section .in this instance and have a common wall a, and they are provided with an enlargement d in, which the movable member is housed. The'wall c is duplicated, round the shaft f, by a partition e, in such 'a way as to clear and enclose said shaft. Slits i are provided in the partitions c and re the passage of the discs h, tongues 7' being left between the slits.
It will be evident that when the movable member revolves, whether continuously or not, it will always occupy the samespace, will keep the slits z obstructed. all the time,
and will conveyheat-from one conduit to the other.
It is known that the coeflicient, of heat transmission between fluids and solids, such as the discs h, increases. with their relative yeloclty. Whatever the velocity of the fluids n the two conduits, it is always possible to lncrease their velocity in relation to' the movable member to an unlimited'extent by increasing the rotational velocity of this latter. Hence it ispossible, with a small apparatus, to obtain considerable exchanges of heat without the velocity of the fluids in their conduits being'high. p
The shaft 7' beingarranged transversel of the path of the fluids, it is possible, without lncreasing its operative portion lengthwise, to mount the bearings 9 outside, so as to facllitate cooling and inspection. Any desired de ree of tightness at the slits 2 may be obtaine by providing the edges of said slitsin the walls of the conduits either with members making a light frictional contact with the discs h, or by providing expansion chambers, of the baflle or labyrinth type, 'withoutcontact. By providing them with scrapers of any known type (not shown) the cleaning of the movable member can be effected automatically. J y
Finall any unavoidable leakages ma be rendere of no importance by causing them to return to one of the conduits, asthe result of a difference in pressure. For example, if it be desired to have the, air very pure, with a view to using it for drying, all that 'is needed is to adjust the fans in such away that the pressure in'the air section of the apparatus is higher than that in the gas sectlon. The gases will contain a' little air, but the air will be free om gas.
The tongues jleft between two consecutives slits'z' in the wall 0 ma instead of surrounding the shaft f as in igures 1, 2 and 3, simply clear it, as in Figures 4 and 5, or again may be cut off to allow it to pass, asinFi res6and7.
The air heater described'above' has given merel by way ofexample.-
WhatIcaim'is:- 1. A. heat' exchanging device comprising gnduits for .two different-fluids separated by common wall having a plurality of slits erein, a heat transmittin member formed of a plurality of rotatab e bodies passing through said slits and having a common axis arranged perpendicularly to the direction of flow of both fluids, and means for causing said bodies to. rotate whereby they pass alternately from one fluid to the other.
2. A heat exchanging device comprising conduits for two diflerent fluids separated by a' common wall having a plurality of slits therein, and a heat transmitting member consisting of a rotatable axle provided with a number of disks passing through said slits, the axle being arranged erpendicularly to the directionof flow of hot fluids.
3. A heat exchanging device including a plurality of conduits adapted to confine two fluids at difierent temperatures and havin a common wall between the same provided with a number of slits, a rotatable axle extending through opposite walls of said conduits, bearings for the axle situated ex teriorly of the conduits, and disks fixed on the axle and extendingv through the slits, whereby when the axle is rotated the disks will revolve through said slits from one conduit to the other.
In testimony whereof I hereunto afiix my signature.
