Torsten Ramn, Stockholm, Sweden Application June 14, 1945.;SerialNo;599,461.

In Sweden A ugustf'i, .1941

Section 1, Public Law 690; August 8'; 1946 Patent expires August 7', 1961 The present invention relates to apparatus for heat exchange between liquids of the kind in which. a great number of conduits are arranged in a casing for the passage-of one liquid, while. the other liquid is conducted between or'around said channels;

The object of the invention is to provide an improved heat exchange-apparatus of said kind in which the conduit" for the passage of, one of the liquids may be inspected and cleansed from deposits and which at the same time has a good,

According to a suitable embodiment of the invention each of the elements comprises two plates welded together along the edges, which plates are provided with longitudinal grooveshaped stampings, which stiffen the elements and which may be arranged opposite to each other and of such depth that they touch each other thereby together forming distance pieces between the two plates of an element.

The plates that form theelements-are further preferably provided with projecting pressed out portions forming distance pieces between adjacent elements.

An embodiment of a heat exchange apparatus according to the invention is shown on the accompanying drawings.

Figs. 1 and 2 show two longitudinal sections at right angles to each other through the apparatus, the section in Fig. 1 being taken between two adjacent elements.

Fig. 31 shows a section taken along the line IIIIII in Fig. 1.

Fig. 4 shows on an enlarged scale a fragmentary side view of one of the elements included in the apparatus.

Fig. 5 shows a section through a pair of the elements taken along the line V-V in Fig. 4. I Figure 6 is a sectional view on an enlarged scale taken on lines VIVE[ of Figure 2 and illustrating the manner in which the plate elements are attached to the frame elements.

11.0mm. (ci- 257445) a it.

Figure? isa; sectional view taken along line The,- he-at. exchange. apparatus consists of a l. substantially rectangular, elongated? casing i in which arelinserted aigreat number of hollow: flat parallel elements 2. which form: channels: for the passage of: one -:liquid, .while the otherv liquidfiows through the: spaces; 3; between: said elements; Each of thev elements:v consists: of' twov plates welded together. at: ivalong the edges. The-open ends offthe. elements are-i welded to: trays-like frames 5 and 6 respectively shown in Figures 6 and '7. As indicated, the open ends of the flat element are bent outwards and are welded to the adjacent elements in such a way that the welded, bent out parts together form a separat ng wall in the spaces between the elements, whereafter the ends of the set of elements thus welded together are welded to the frames 6 as shown at IS in Fig. 6.

The casing l is provided with in etand outlet-pipes 1 and 8 for the liquid that is flowing through the spaces 3 between the elements. To

the frame 5 is weded a flange 9, which is fastened between a flange ll] of the casing and a connecting pipe II for the connection of the heat exchanger with a supplyor d scharge-pipe for the other liquid flowing through the elements. The other frame 6 is welded to a tube I2 on the end of which is screwed a flange I3 for connection to a pipe line. On the upper part of the casing I is welded a tube M which surrounds the tube I2 and together with the dispaceable packing gland l5 forms a stufiing box, which is adapted to tighten against the tube [2. All the elements 2 together with the frames 5 and 6 and the parts fastened to the same form a single unit which can be loosened and. taken out for inspection and cleansing. For this purpose at first the flange l3 hasto be unscrewed and the gland l5 loosened. The pipe II is next detached after which the whole set of elements can be taken out through the bottom of the casing. Whie the whole set of elements is rigidly connected to the casing I by means of the flange 9, the other end of the set of elements is displaceable relatively to the casing by means of the stuffing box [4, l5 for permitting the elements and the casing to freely expand and contract during changes of temperature. v

In the plates forming the elements longitudinal groove-shaped stampingslfi are made for stiffening the elements.

These stampings can be arranged opposite to each other and be so deep that they touch each Apparatus for heat exchange between liquids,

comprising, in combination, a casing, a set of fiat, substantially rectangular hollow elements within said casing for the passage therethrough of one liquid, said elements being disposed in parallel relationship and spaced apart from each other, the other liquid being passed between and around said elements, each of said elements comprising twoplates secured together along their longitudinal edges, said plates being provided with longitudinal grooves extending along the whole length of the elements and arranged opposite each other and of such a depth that they touch each other, thereby together forming distance pieces between the two plates and at the same time serving to stiffen the element against pressure from outside, said plates being further provided with projecting, pressed out small knobshaped distance pieces serving to stiffen the element against pressure from within, said knobs be- 7 ing arranged in longitudinal rows about half-way between the longitudinal grooves leaving free spaces between adjacent knobs for the liquid flowing along the outside of the elements, frames attached to the ends of said elements and so arranged that the elements together with said frames can be removed from the casing as a single unit for inspection or cleansing, means rigidly connecting the whole set of heating elements with the casing at one end, a stuffing box, the other end of the set of elements being held tightly against the casing by said stufflng-box and being displaceable relatively to the casing, so as to permit the elements and the casing to expand and contact freely relatively to each other upon changes in temperature.
