,a-m m Patented oct. 1, 1935 Application May 4, 193a, Serial No. 000,441 In Norway May 7, 1983 '9 Claims. I (01. 251-139) The invention relates to radiators of the kind comprising two plates connected preferably by means of welding along their edges, one plate being provided with hollow ribs for the'heating medium.
Known radiators of this kind have the disadvantage that the hollow ribs with a view to securing sufliclent strength can be made with a comparatively small height only, as at the working pressure commonly used they easily expand with the result that both plates bend which may give rise to leakage. Such radiators therefore could be given only a comparatively small heating surface relatively to their dimensions (heigl$ and breadth); According to the present invention this disadvantage is removed. The hollow ribs are curved in the longitudinal (vertical) direction in the form of a waving lineor similar curved or broken line, instead of being made straight as usual. Tests as well as experience in useha've proved that the height of such ribs may be increased to more than double the height allowable for straight ribs. A further advantage in connection wi-th the .said curving of the ribs is that their heat emission by convection is materially increased. 7 The necessary communication between' the ribs I for the circulation of the heat medium-as a'rule steam or hot water-through the radiator may be secured by providing the plate, connected with. the plate with the said ribs, with channels, preferably depressed in the plate, which are open towards said ribs. The said channels may be arranged'in a. suitable number transversally to the ribs in the other plate (1. e. horizontally) ,or
one or more horizontal channels may be arranged at the upper and lower ends of the radiator and connected by means of vertical channels.
The plate (hereinafter termed front plate) connected with the rib pla-te (hereinafter termed back plate) also may be quite plane, which often is desirable from an architectonic point of view and which also gives a cheaper construction of the radiator. According to the invention the communication between the ribs in this case may be obtained thereby, that the parts between the ribs, in a plane normal to the front plate, are bent in a wavy line or broken line in such way that the said parts only in some places extend to the front plate and may be welded to the same, whereas in other placesthere is a free opening between adjacent ribs.
The number and location of the free openings betweentheribsmayvary. Witha view toobtaining cheap manufacture, all ribs and all parts between adjacent ribs preferably are given the same shape, so that the said free openings between the ribs are located on a straight line across the radiator.
According to another embodiment of the invention, the communication between the ribs is secured by inserting flat iron pieces or pieces of other profiles between the two plates which pieces are welded to the front plate for stiffening the "10 same, and preferably also to the parts between the ribs of the back'plate, free passages between the ribs being left between the said-flat iron or the like pieces. The front plate in this case is preferably made plane and with a bent flange 15 along the edges, with a height corresponding to the height of the said pieces.
Further features of the invention are described hereinafter referencebeing had to the drawings which illustrate embodiments of the invention.
Like reference numbers indicate corresponding parts in all figures.
Fig. 1 is a rear elevational view :of a radiator showing the curved ribs, Big. 2 is a vertical section through the radiator between two ribs, Fig. 3 is a horizontal section taken on the line 0-0. of Fig. 1. Fig. 4 is a front elevational view opposite to that shown in Fig. 1.
Fig. 5 is a rear elevational view of a modified design, Fig. '6 is a'vertical section through the same. Figs. 7 and 8 are horizontal sections taken on lines b-b and o- -c respectively of Fig. 5. Fig.9 showsin a partial vertical section a modification of the radiator.
Fig. 10 is a rear elevational view of a further modified construction, Fig. 11 is a vertical. section through the same and Fig. 12 "a horizontal section taken on the line H of Fig. 10.
In the drawings I indicates the rear plate of the radiator with hollow. ribs 2 which accordingto the invention are curved in the longitudinal or vertical direction in a wavy line. The ribs are closed at their topand bottom ends, preferably by welding. 3 indicates the plate-in this specification referred to as the front plate-eonnected to the rib plate I along the edges of bothv plates.
In the embodiment illustrated in Figs. 1-4, the front plate 3 is provided with depressions 4, I,
forming horizontal and vertical channels communicating with the hollow ribs so as to secure circulation of the heating medium through the radiator. In order to accommodate the inlet and outlet sockets I and I for the heating medium, the two outermost ribs 2a and 2!: do not extend to the top and bottom of the radiator, and the plate I in this place is flat so'as to cover the channel 4. The path of the heating medium through the radiator is indicated with dotted lines in Fig. 4.
In the embodiment illustratedin Figs. 5-8, the communication between adjacent ribs 2 is obtained by bending the material between the ribs in certain places in the direction away from the front plate 3, so that passages as indicated at 9, 9 are formed between the ribs. The front plate 3 is plane with a bent flange l along the edges, where it is welded to the edges of the rib plate I. The parts between the ribs are in the places where they are not bent, in contact with the front plate and may be welded to this plate at as many places as considered necessary for the stifiening of the same. The amount that the outer wall of the outermost ribs on both sides of the radiator projects forwardly is decreased corresponding to the extent of the flange of the front plate and welded to the same as indicated atll,inFig.7.
In the modification shown-in Fig. 9, the front plate 3 is wholly plane, the bent parts of the plate I between the ribs being located at some distance from the ends of the ribs. In other respects the construction is the same as shown in Figs. 8, of course with the exception that the horizontal dimension of the outer walls of the outermost ribs on both sides of the radiator is the same as the amount of projection of the ribs.
Figs. -12 illustrate an embodiment of the radiator in which the communication between the ribs is obtained by fitting of fiat iron pieces l2, l2 between the plates. These pieces are welded to the front plate 3 at as many places as necessary for stiffening of the plate, and preferably also welded to the parts of the back plate between the ribs. The front plate is provided with a bent flange around its edges, projecting an amount corresponding to the width of the fiat iron pieces, and welded to the rib plate.
In the embodiment shown the flat iron pieces are parallel and the same distance one from the other, and perpendicular to the ribs, but they may be arranged at different distances and at other angles to the ribs as may be found suitable for the stifieni g of the front plate and the communication between the ribs.
In the radiators illustrated in the Figs. 59
. and Figs. 10-12, the outer rib 20 on the left-hand side oi. the drawings is made somewhat broader than the other ribs in order to obtain across section sufliciently large to enable the inlet and outlet sockets 6 and for the heat medium to be located on the side of'the rib.
Preferably, flat iron pieces l3 are arranged transversally on the top of the ribs in the upper and lower part of the radiator as shown in Figs. 5-8, welded to some or all oi. the ribs and serving partly for stiflening the ribs and partly for supporting the radiator.
What I claim is:
1. A radiator comprising two plates connected along their edges, one of the plates being pro- 5 vided with hollow ribs for the heating medium, the parts of this plate between the ribs being bent in some places in the direction away from the other plate so as to form passages between adjacent ribs.
