The object ci' the present invention is a therinic exchanger, allowing the caloric or frio-critic energy of one fluid to pass over to another iiuid in a continuous manner, by means of the interposition of a ceramic, nietallic, mixed or other sortoi'partition; the said exchanger being particularly characterized by the fact that the channels, ink which the fluids circulate, are arranged in such a Way that all the partitions are substantially in Contact with'the two fluids, thus reducing the weight and encumbrance of the apparatus to ka minimum `for the same'exchanging capacity.

According to another particularity of the invention, thevwhole apparatus is built Vup by placing side by side alternately two types oi piling up elements, conveniently lodged in interlocking relation so as to constitute alternatively in the succeeding pilings rec-- tangularly directedV conducts, intended resiectivel for thepcirculation oithe one orV l y I the other i'luid. Y

Other characteristics will result from the following description: Y

In' the annexed drawing, which is given merely by way of example:

Figure l is a vertical longitudinal section on the line l-l in Figure 2 of one exchanger, according to the invention;

Figure 2 is a vertical transversal section on the line 2 2 of Figure 3.

Figure 3 is a horizontal section on the line 3-3 oi Figure l.

Figure 4lis a horizontal section on the line ll-lof Figure 2.

Figure'5 is an elevational view of a constitutive element of the iirst type of pilings. Figure '6 is the corresponding plan view.- Figure' 7 isy a vertical section on the line 7 7 of Figure 6.' i n Figure S is an elevational view of a second element cooperating with the preceding in the formation of the first pilings.

FigureQ is the corresponding plan view.

ve'scapeat B, after passing as per arrow fully traced Ythrough the horizontal channels C. The horizontal and vertical baille platesk D and E allow to increase considerably thev travel of the fumes. y

The cold air, which is to be heated, arrives 'from below in F and raises as per dotted arrows into the conduits G and passes out into the upper collector H from which the warm air issues bythe conduit l;

lt will be seen from this that the recovery is methodical, since the fumes travel in an opposite direction to the air that is being heated;

'Accordingto one of the features of this inf vention, the elements that constitute the conduits .C and G are such that'ally their partitions are in contact with the two fluids@ in 'this particular instance, thisy result'is 'obtained by placing side'by side two types A.of vpilings J1 J2 shown especially in-'Figure 2. i

@The pilings yJ are obtainedby the superposition of rows, which are formed alter- 'natively by placingside by side the elements Kand L. The elements K (Figures 2-5-6-7) have a vertical U-shaped section, transversal tojthejpilings J1' 5). The elements L (Figures 2-8-9-10) have avertical T-shaped seetionltransversal to the'pilings J1 (Figure parallel y to the piling v,J1 (Figure 8) The .pilings J2 'are constituted bythe super-vv 7^ position; ofidentic yrows formed by placing side f by side elements M (Figures 2-11- '12?13), of vvertical T-shaped section, .pen

pendi'cularltothe pilings2 (Figure V13) and".

1 of horizontal section in forni of a double ico The lateral wings m of said elements M eX- tend between two consecutive U-shaped members K.

The Echanger is, of course, completed by any other elements of current or yspecial shapes intended for making bellies and channels near the walls. Y

Furthermore, in the case oi ceramic `partitiene, these are disposed in such a way as to allow the free expansion oi all their` parts, so as to avoid their'rupture and to prevent the mixture of the two fluids, the ioints being, for this same purpose, conveniently vcrossed and provided with suitably placed ointings, thus allowing a construction composed of several materials of different nature.

The invention is not limited to the embodiments shown and described, which have merely been chosen as Van example. It has been supposed that the pilings were vertical, but it is quite evident that the invention applies to exchangers in which the pilings Il and J2, or similar, might be replaced .by s uperposed layers. i y

Having no-w described my inventionV what I claim as new and desire to secure by Letters Patent is: Y

l. In a heat exchanger` a number of aligned spaced longitudinal conduits 'for a first liuid, spacing members between each two consecutive conduits, and `partitions on either side of said aligned conduits and separated from said conduits, whereby transversal conduits are formed for a second fluid between each partition and the alignedlongitudinal conduits. y e

2. In a heat exchanger a number of aligned spaced longitudinal conduits for a first fluid,

spacing members between each two consecutive conduits, and partitions on either side of said aligned conduits, separated from said conduits and provided with ribs extending between each two consecutive longitudinal conduits, whereby transversal conduits are formed for a second fluid between each partition and the aligned longitudinal conduits.r

y y3. In a heat exchanger a number of aligned U-shaped spaced members, a T-shaped member between each two consecutive U-shaped members and adapted to close the open side of one of said U-shaped members and to bear of aligned U-sliaped spaced members, a T- shaped member between each two consecutive U-shaped members and adapted to close the open side of one of said U-shaped meinbers and to bear against the middle web of tie other U-shaped member, whereby long"- tudinal conduits are formed by the hollow spaces in each U-shaped member for a first fluid and partitions between each two consecutive rows of aligned" U-shaped members provide-d with Vribs extending between each two consecutive -sliaped members in the spaces left free between the wings of the T-haped members, whereby transversal conduits are formed for a. second fluid between each partition and each row of aligned U-shaped members.

5. In a heat exchanger a numberof rows of aligned U-shaped spaced members, a T- shaped member between each two consecutive U-shapcd members and adapted to close the open side of one of said U-shaped members and te bear against the middle webA of the other tlf-shaped member whereby longitudinal conduits are formed by the hollow spaces in each lll-shaped member for a first fluid, and aligned adjacent T-shaped partitions betweeneach two consecutive rows of aligned 'Ll-shaped members having their lateral wings extending between each two consecutive lai-shaped members in the spaces left free between the wings of the T-sliaped members, whereby transversal conduits are formed for a second fluid between the T- shaped partitions and the U-shaped members.
