3 Claims. 257-262) My invention relates to that class of devices which are employed in the transference of heat from 'or to a fiuid flowing through a conducting tube, and an object of my invention, among o hers, is to create a radiator of this type that all be simple in construction and particularly eflicient in operation.
One form of a radiator embodying my invention and in the construction and use of which 0 the objects herein set out, as well as others, may
be attained is illustrated in the accompanying drawing in which- Figure 1 is an end view diator.
Figure 2 is a view in front elevation with the central parts broken away.
Figure 3 is a view in section on a plane denoted by the dotted line 3-3 of Fig. 2.
Figure 4 is an end view showing a modified go form of apparatus embodying the invention.
Figure 5 is a view similar to Fig. 2 of this last mentioned device.
Figure 6 is a view in section on a plane denoted by the dotted line 66 of Fig. 5.
This invention embodies that type of a radiator comprising coils for the circulation of a fluid for the purpose of transferring heat and while it is particularly applicable for refrigerating purposes it will be understood that it is not necessarily limm ited to such.
In the accompanying drawing the numeral 1 denotes a tube or tubes in the form of a coil or coils and which is employed for the purpose of conducting a fluid from one point to another, the fluid as it flows through the coil either collecting heat from the surrounding atmosphere or transferring heat thereto, depending upon the particular use for which the apparatus is designed. Ends 8 and 9 are suitably connected to sources of supply and delivery in a manner that will be thoroughly un derstood by those skilled in the art and for which reason a showing of such is omitted herein. The coils are commonly supported in a frame comof my improved raprising end plates l0 and II in any suitable greater degree if desired.
manner.
In the use of apparatus of this kind it has been common practice to attach radiating elements as flns or plates to the coils, arranging such fins at slight distances apart along the coils and at 50 right angles to the axis thereof, said fins having holes through which the coils extend and which serve as a means for attaching the fins to the coils as by soldering or otherwise. It is a purpose of the present invention to increase the efliciency of these radiating elements by constructing them such currents to impinge but instead of being of in such manner that a mazdmum amount of the fins may be in contact with the coils to produce increased radiating effects, and also in so disposing the fins thatfincreased efliciency in their action may be produced. In eifecting this pur- 5 pose'the flns, in one form of the invention, are of V-shape comprising branches |2l3 projecting across the coils and disposed with their planes extending lengthwise of the coils, as shown in Fig. 2. These fins or plates are preferably ar- 10 ranged in inclined positions relatively to the general direction of flowof air between the tubes, as indicated by the arrows in Fig. 3 of the drawing. The efiect of this arrangement is to deflect the air currents from the general direction ll of flow between the coils or tubes and cause against the fins and thereby increase the conductivity of such fins find consequently the rate of transference of eat.
As hereinlbefore remarked the coils extend between the branches of the fins, and in order to obtain a maximum amount of contact between such coils and the fins the latter are provided with recesses I 4 on their inner surfaces, in the preferred form of construction the fins being bent to shape as shown in Fig. 3 to create such recesses. These recesses envelop the coils to a considerable extent and a maximum area of contact is therefore obtained between the fins 3 and the coils. If desired the fins may be secured as by soldering or otherwise. In that form of the structure shown in Figs. 4 to 6 the coils or tubes I are arranged substantially as hereinbefore explained between fins. The fins are arranged 5 diagonally to the direction of flow of air currents V-shape, as shown in Fig. 3, these fins constitute substantially onehalf of the structures shown in Fig. 3, as if the upper part of each of the fins shown in Fig. 3 were omitted. In this arrangement of the fins 40 the recesses l6 envelop the tubes or coils to a somewhat greater extent than in the other form of the structure and they may be inclined to-a In both forms of structure, however, the fins preferably extend for the whole length of thecoils between the plates l0-l I. The end plates ll may be connected as by means of rods I7, such rods, however, being omitted from the showing in Figs-.2 and 5 in order not to obstruct the view.
In accordance with the provisions ofthe patent statutes I have described the principles of operation of my invention together with the device which I now consider to represent the best 5 2 embodiment thereof; but I desire to have it understood that the device trative and that the invention may be carried out by other means and applied to uses other than those above set out.
I claim:
l. A radiator comprising a tube having a fln of v-shape in cross section extending longitudin'ally of said tube, each branch or leg of said fin being recessed longitudinally intermediate its free edge and the apex to engage opposed wall portions of said tube.
2. A radiator comprising a series of tubes, and a fin of V-shape in cross sectionextending longitudinally of each of said tubes, each branch or shown is only illusleg of said iln being recessedlongitudinally intermediate, its free edge and the apex to engage opposed wall portions oi each of said tubes.
3. A radiator comprising a series of tubes, and
a series of fins each of V- nape in cross section extending longitudinally of each of the tubes with all of the similarly positioned sides of the diflerent tins arranged in parallel relation at an angle to the direction of intended flow 'of air relative to said tubes, each branch or leg of said fln being recessed longitudinally intermediate its free edge and the apex to engage opposed wall portions of each of said tubes.
