. V The invention relates to a heat exchanging Fig 6 is an 'end elevation of a heat exelement working according to the cross curchangmg batte composed of'six elements;
rent eprinciple which consists of any number Fig. 7 is a si e elevation of Fig. 6; 55 of c is composed of lates which have angle F1 8 and 9 showotwo ways of arrang- 5 portions cut out of t e corners. mg t e element in (connection with a fan.
The free edges of the plates are alter- Fig. 10 .is a detail per tiveview of the nately bent upward ordownward so that lower portion of one of t e corner pieces and these superposed plates form cells, which a corner of the bottom plate with the angle so may be sealed at the edges. The cells. bars thereof, the interfitting parts being 10 formed are alternately open at the longiseparated.
tudinal sides and at he cross sides so that\ The heat exchanging element 0 consists in the element two sets of channels one set of abottom plate 1, a top plate 2, and in- I for the air and the other for the heating termediate plates 3. All these plates have as, gases, are produced, which are utilized for angle portions 4 cut out atthecorners, The 16 the exchange of heat, the separation of the intermediate plates 3 have two of their ed air and gas channels, the one from the other bent upward and two bent downward so 52 is effected bymeans of corner pieces fitting for instance the edges 5 at the front and into the cut out portions at the corners of rear of the lower intermediate plate 3 are 10 the latcs. bent downward and the edges 5 at the sides so e independent cells are" subdivided by of the lower intermediate late 3 are bent undulated stri s of sheet metal and all the" upward, while the next fol owing plate has parts of the e ement are connected the one the edges at the front and rear-bent u ward with the other by transverse bolts and nuts and the side edges bent downward. f B1 this" ll so that the plates forma rigid body without manner, cells 6 are formed, between the soldering o the edges of the plates which superposed plates 3 the said cells being alterare in contact. nately opened or closed at two opposite sides The transverse bolts can be tubular and whereby two flues, each havin a plurality provided with holes so that if the outer ends of passages are formed, of w oh the one so of the said bolts are connected with a steam serves for. the air or other medium to be pipe, the cells can be easily cleaned by blowheated andthe other for the heating gases. mg'the same out or in any other convenient The gas and air flues are separate one manner. from the other by means of corner pieces In order that the invention ma be clearly 7 (Fig.. 1) which are inserted where the r- 5 understood, I shall proceed to esicribe the tions 4 at the corners of the element ave same with reference to the several forms of been cut; out. Y construction shown by way of example on The individual cells are subdivided by the accompanying drawings, wherein undulated strips 8 of sheet metal arranged Figure 1i! aperspective-view of aheat exparalleltothe closed ends of the cells and changing element, the corner piece having serving-at the same time for spacing the 1 i been removed from the front corner; plates 3. In the outer plates 1 and 2, as
Fig. 2 is 'aview similar to Figure '1, the well as in the intermediate plates 3, holes slide frames and the upper end plate being are ,provided which serve for the reception removed the u per intermediate plate being of. the transverse bolts 9. Them bolts are as shown partly roken away; arranged in such a manner that'they are-sit- Fig. 3 is'a detail view on a larger scale uated alternately first 0 one side and then of one of the corner pieces; on the other of the undu ated strips'8, 8' of Fig; 4 is a. detail view illustrating how sheet metal. All of the plates of anelement the corner piece'is fixed between the outer are rigidly connected one with theother by 100 walls of the element; means of nuts 10 screwed upon the threaded Fig. 5 is a section on theline 5-15 ofFig. ends of the transverse bolts 9. If the ress- 7 of. an element with tubular transverse ing together of the plates by the nuts ouldbolts for the blowing out of the gas cells not be suflicient to make airtight joints ber so that the gas flues can be blown out and cleaned by steam under pressure. The cleaning may be clearly done mechanically. The bottom plate 1 and the top plate 2 have flanges 14 between which thecorner ieces 7 are inserted. The corner pieces are built up of large angle bars 15 and smaller angle bars 16 and the angle bars 15 are fitted against the plates where the portions have been cut out at the corners. To make thejoints gastight the plates may be secured to the bars 15 by soldering.
Although the heat exchanging elements can be made in anyrequired dimensions, the sides of the same are however limited by the fact that in commerce, plates of sheet iron are to be obtained, only in determined dimensions. An enlargement of the elements by welding or riveting! together the sheet iron plates found on the market would be much too expensive and troublesome, not'to mention that it would be scarcely possibleto protect such large lates against ;warping under the heat. If, ,t erefore, larger heating surfaces are required than those of one element, several elements a arecombined into agroup (Figs. 6 and 7), return bends a being used for connecting the elements of the superposed rows in such-a manner that the cells of the elements which are open at the side are connected the one with the other. Air is sentthrough aggregations of the elements in the direction ofarrow 2, the heat ing gases flowing through'the aggregation of elements in the direction of, arrow 1 and having their direction offlow changed by the return bends 8. By the arrangement described, a combined cross current of the two media, is produced which ensures an intense utilization of the heat. The individual elements 'can-be connected. andarranged in any convenient manner in accordance with the requirements of a determined direction of current. The returnbe'nds can be used either for the air flues flor for theflues of heating gases or for both flues according to a the type of the plant. :Theendboxesmf the gas channels of a group-of elements and the return bends s servelas se arators for the impurities admixed with-t eas so that the cleaning of the apparatus is facilitated- If the media traverse such an aggregate a loss of speed will occur ateach changeof direction whereby the lossesresulting from friction are considerably increased so that an undesirable decrease of speed might occur. This inconvenience may be avoided as shown in Figs. 8 and 9," by substituting a fan '0 for" one of the return bends s.
In the form of construction shown in Fig. I
8, thedirection of the air current only is altered-and the speed of the air, is mai n-,
