ay portion ance with a portion of a cooler on and'Fig. 4- 1s a sectlon fve'd longitudinallyfe'xtending ngitudinally-e `g With al plurality ovideda plurality of corrugated of oppositely-disiosedcorrugation' forming substansides Aof a square.v and 'a porverticaleection In the construction secure this object tructed i 'the cooler that the Xtending portions oi"y one set into the corrngation of Xte'n'ding portions into rpernsverselyextending' municatofwith eachand. transverse portions.v

formed vof .opposite.llVf-diS-lAv posed parallel Walls'lll and 1`5v-n the: cual-actors "or"y diagonal connecting portions 13 ofthe 'con-f is a section parallel to` the end elevation shownr in Fig'.` 1,' and showing the. conduits in section; Fig. 3 is a. perspective View o' an enlarged Scale, d similar to Fig, 2, lbut showing the, corrugavtions With cui portions.

conduit were not ink duits these Walls extend parallel and at anangle to theadjacent Wal portions, and are spaced .apart a distance equal tothe Width of the conduit at the longitudinally and at the transversely-extending portions thereof. The length of the diagonal connecting portions 13 is such that the Walls of the1longitudinally-extending portion 11 of each conduit at the point at which it bridges thecorrugation of the adjacent conduit is in perfect alinement with the Walls of each alternate extending portion of said last-mem tioned conduit, thus greatlyv strengthening the construction as a Whole, eliminating the right-angle turns in the co/nduits, and facllitating the flow of fluid therethrpugh.

For spacing the wall plates the proper dis' tance apart, I preferably provide a Wire 16 bent to the desired form and of any suitable shape, as, for instance, square in crosssection. One of the plates, as plate 15, is of somewhat greater length thanthe opposite' plate`14, and .this longer plate is bent to extend across to the outer surface 17 of the Wire 16 and to form an mWardly-directed flange 18 in engagement with the plate 14,

as is clearly illustrated in Fig. 3. The Wire at the intersection ofthe longitudinally-extending portion and the transversely-extending portion is` of reduced cross section, so

' that the longitudinally-extending portions present straight vertical columns,.the diagonal meeting line being largely concealed by the solder which is applied `to secure the parts together. Y At a point closely adjacent the wire 16 the Wall forming the inner surface of the. corrugation is bent to form the diagonal inner wall'of the connecting -portion 13 of the conduit. so that the flow of the fluid `throughthe conduit is unrestricted, but' this diagonal Wall is practically invisible from the outer surface of the cooler and does not detract from the.straight column eiect produced by the successive longitudinally-- extending portions. y

Preferably the walls forming the conduit are parallel at all points, but it is not essential that they extend perfectly straight. In Fig. 4, the longitudinally-extending-portion 11* is formed of parallel Walls, but these parallel -walls are each curved not only to increase the radiating surface, but also to increase the strength of the apparatus and to prevent the adjacent Walls from collapsing under excessive strain. Identically the same spacing Wires are employed in connection with the form illustrated in Fig. 4 as those illustrated in the lother figures. In each case, the spacing strips or wires have straight longitudinally-extending portions and vstraight transversely-extending portions at the intersection of A'which there is a right angle on the inner side and abeveled or flattened surface on the outerside. iWhere the lcngitudinallyfextending;\fpgijtons" of each corrugation are also corrugated, these vcorrugationsextend only to the spacing strips and are practically invisible from the front side of Ithe cooler. In each case the straight column effect is produced and the`union ofv the severalfco'nduits and their lines of interf j section are concealed by the solder.

Having, thus described my invention. I claim as new and desire to secure by Letters Patent: i

AnV apparatus of the class described. comprising corrugated 'conduits juxtaposed to' form intervening spaces or passages, the bends or corrugations in one conduit being in alinement with and bridged by eorrespond-ig corrugationsy of an adjacent con duit. and the bridging portion of each bend or corrugation being itselflcorrugated and communicating with Veach adjacent side portion by an unrestricted 'diagonally-disposed connecting portion having oppositely-v disposed parallel Walls. f
