Application filed December 30, 1916. Serial No. 189,770.
To all whom it may concern:
Be it known that I, ARTHUR B. MopiNn, a citizen of the'Unitedbtates, residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in a Radiator, of whlch the following is a description.
My invention relates to; means for controlling the te'mperature of the cooling fluid f3: an internal coinbustionengine or the l' e.
The object of my invention is to produce a simple, efficient, reliable, light and comparatively cheap device of the kind. described, in which the circulating fluid and air ar so manipulated that the size and weigh of the radiator'may be greatly reduced without reducing the capacity of the radiator.'

device. 1
To this end my invention consists in the Fig. 4 is a section taken substantially on line of 4-4 of Fig. 3. I i
Figp5 is a front elevation of a complete Fig. 6 is: afragmentarv side elevation of "another modified form of my device.
Fig. 7 is a section taken substantially on view of one Fig. 8 is a fragmentary-plan v of the vanes shown in Figs. (Sand 7.
Fig. 9 is a view similar to Figs. land 3 but showing a'modified form of vane. i
Fig. 11 is a view similar to Fig. 1 showing another sli htly modified form of mv device.
Fig. 12 is a view similar to Fig. 1 showing another modified form of my device.
In the form shown in the drawin s my improved radiator comprises a plurality of substantially vertical tubes 1- -1 each formed of copper or other suitable material adapted to readily transmit the heat from the fluid the radiator between them to control the temperature of the fluid in the'tubes.
In the preferred construction each wall of the tube is provided with a series of transverse substantially semi-cylindrical corrugations throughout its length, the corrugations on one side of the tube being spaced intermediate the corrugations upon the opposite side so that the cross section of tube remains approximately uniform throughout its length while the center line of the tube follows a zig-zag course. The projecting margins of the tube however are substanperpendicular throughtially straight and out their length.
In the preferred construction the several tubes are suificiently spaced from each other to receive a spiral vane between them each snugly fitting in the corrugations 2 and 3 in within the tube to the air passing through adapted to readily transmit and rad ate heat and are each soldered. brazed or otherwise hermetically attached to the wall of the tube so as to facilitate the transmission of heat to the vane thereby increasing the available radiating sur ace of each tube. ,In t e preferred construction the vanes or plates .4 are each twisted or curved so that air passing through the radiator be ween the tubes and vanes will receive a spiral or whirling .motion thus forcing by centrifugal action the cooler and heavier air outward against the radiating surface of .the tubes as it .passes through the spaces between them and will also contact with the surfaces of the vanes and prevent a layer ,of partially warmed air enveloping the various heating surfaces. Obviously the coolest air will be thrown against the tube surfaces and the outer portions of the vanes,while the warmer air will seek the central portion of the tubes where the vanes have radiated a considerable portion of their heat. thus actually arranging the air as itpasses through the radiator to obtain the greatest possible efiiciency in dissipating the heat from the cir-,
the tubes 8' and 9 and connected thereto by the'plates or vanes 11 and 12 respectively. The strip 10 and plates 11 and 12 are preferably connected to each other and to the tubes 8 and 9 by brazin'g,soldering or other hermetical attachment so as to provide for the greatest possible tran mission of heat to the plates and strip to secure the greatest heat dispersing efliciency, and while the dissipation of heat will ordinarily be less in this form of my device than in the form previously described, the construction renders it very desirable under some conditions.
In the form shown in Figs. 9 and 10 the tubes are constructed and arranged substantially as shownin Figs. 1 and 2. The vanes for each pair of tubeshowever are formed ofa'single strip 1 1 corresponding in length to the length of each tube and of approximately the same or a corresponding width. A plurality of lateral slits or openings are, formed in the strip 14 each extending from one edge of the strip to a point near the. opposite edge, the several slits being spaced v to accurately correspond to the spacing of the corrugations upon the tubes and the parts or tongues 15 thus formed are each twisted or formed into a spiral vane s'ubstantially as hereinbefore described and the entire strip ispositioned between the tubes with the several spiral tongues positioned in the corrugations and hermetically attached thereto as hereinbefore described. 7
In .the form shown in Figs. 6 and 7 the radiator comprises a plurality of suitable tubes 16 arranged in rows both laterally and transversely of the radiator and a series of plates 17 are positioned between the several tubes; each extending through a suitable opening in each of the plates 17 to'rigidly maintain the .tubes in'position. In this form v a plurality of sections 18 are severed from the plate 17 along two edges and one end leaving, each section attached to the plate at one end only. Each section is then twisted to form a spiral and the several sections are so spaced and positioned as to substantially 'form a continuous spiral extending transversely of the tubes the entire width of the plate 17 whereby the air passing through the radiator betweenthe tubes will be given a spiral or whirling motion as hereinbefore described. The operation of this form is not as effective under ordinary circumstances as the forms hereinbefore described but increases the efi'ciency of this type of radiator materially.
In the-form shown in Fig. 8 the spiral 19 corresponding to the spiral 18 hereinbefore tubes 20 howeverare bent to form substantially rectangular passages through the radiator with the walls ofthe passages substantially horizontal and perpendicular while in Fig. 12 my spirals are provided in rectangular passages, the walls of 'which are inclined at substantially forty-five degrees. The operation however in each case remains substantially the same as hereinbefore described. The whirling,motion imparted to the air by the vanes 22 and 23 respectively tends to produce greatly increased efliciency in a radiator.
:Having thusdescribed my improvement it is obvious that various immaterial modifications may be made in my device without departing from the spirit of my invention, hence I do not wish to -be understood as limiting myself to the exact form or construction shown.
What I claim as new and desire to secure by Letters Patent is.
1. In a radiator construction of the kind described and in combination, a "plurality of water tubes suitably spaced from each other to form bounding walls of air spaces therebetween, and a plurality of spaced radiating plates formed toprovide a plurality of spirals and arranged with a spiral positioned between the tubes andin contact therewith substantially all along" their length for agitating the air. passing therebetween.
