Specification of Letters Patent.
Patented May to, 1922.
Application filed January 22, 1918. Serial No. 213,265.
useful Improvements in a Radiator Core,-
of which the following is a description.
My invention relates to means for controlling the temperature of the cooling fluid for an internal combustion engine or the like.
The object of my invention is to provide a-simple, efficient and reliable device of the kind described in which the air is so directed as.to greatly increase the efiiciency of the device. y
To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described,.
and more particularly pointed out in the v claim.
In the accompanying drawings wherein like or similar reference characters indicate like or corresponding parts,
Fig. 1 is a front elevation of my improved 5 radiator.
Fig. 2 is a side elevation of the same with a part of the frame broken away to show the general construction of my device.
F ig. 3 is an enlarged section taken :substantially on line 3-3 of Fig. 2.
Fig. 4 is a section taken ubstantially on line 4 -4 of Fig.3. Y
Fig; 5 is a view similar to Fig. 4 but showing a slightly modified form of my device.
Fig. 6 is also av view similar to Fig. 4: but showing another slight modification.
In the form shown in the drawings my improved radiator comprises a plurality of substantially parallel vertical tubes 1.l pref- 0 erably arranged in rows both longitudinally:
and transversely of the radiator and connected at their ends to provide for the free and as far as possible, uniform circulation of the cooling fluid through the tubes. In
the preferred form the tubes 1 are each connected at their upper ends, to a reservoir 2 and at their lower ends to a reservoir 3 in the usual or any desired manner 'sothat the cooling fiuid may freely pass between 0 the reservoirs through the tubes which are preferably formed of copper or other'material adapted to freely transmit heat from the fluid 'in thetubes to the air surrounding' them.
In the preferred form also a.plural1ty of transverse partitions 4-4. are provided be tween the reservoirs 2 and 3 each soldered or otherwise connected to the several tubes 1 to provide a metal contact between the partitions and tubes 'to aid in the transmission of the heat from the tubes to the artitions. The partitions serve both to direct the air passing through the radiator between the tubes and as radiating platesor fins to assist in dissipating the heat I from the tubes by providing an increased radiating surface for transmitting the heat from the fluid in the tubes to the air passing between the partitions.
Obviously the efficiency of the cooling-system is dependent upon the intimate contact of the air with the various radiating surfaces as well as the temperature of the air in contact with these surfaces and where the plates are so formed that the spaces between them are substantially straight and unobstructed the air tends to move more rapidlly in the central art of each of the spaces between the partitions and tubes while the ai in contact with the partitions is retarded in its movement by friction and otherwise thus in effect forming an insulating layer of partially heated air adjacent the various radiating surfaces thereby greatly reducing the efficiency of the device. In the form shown in Figs. 3 and 4 the partitions are corrugated longitudinally of the radiator so that air passing between the partitions will be alternately deflected against the upper and lower radiating surfaces of adjacent partitions the velocity of" the air in its movement serving to bring thesame more intlmately lnto contact witlrthe partitions particularly at each point of its deflection, and preventing the formation of a partially heated stratum of airat these points.
In the preferred construction shown each partition is provided with a longitudinal corrugation 5 between each row oftubes' the height of the corrugations corresponding .with the distance between the partitions, that is, in the form shown, each longitudinal row of tubes passes through the several partitions at the bottom of a longitudinal corrugation 0 6 in the several partitions the margins of which extend upward to form an interme diate corrugation 5 and the upper faces of the several corrugations 5 are substantially in line with the lower faces of the corrugations 6 of the next adjacent partition above. The several corrugations are preferably so formed that the air current passing between them will freely follow their general form.
As shown a plurality of projections 88 and 9-9are provided upon the surfaces of each partition, the several projections are preferably formed by partially severing a small portion of each partition along two converging lines and bending the severed portion at an angle to the partition. \Vith the air passing through the radiator in the direction shown the several projections 8 are formed upon the upper face of the partition and are bent upward upon the upwardly inclined sides of each corrugation while the projections 9 are formed upon the lower face of the partitions and are bent downward on each downwardly inclined portion of each corrugation. In the preferred construction the face of each projection is positioned at an angle laterally to the normal direction of the air passing between the partitions so that each projection tends to deflect the air laterally toward the tubes and into the spaces between them thereby tending to secure a substantially uniform movement of the air through the entire length of the radiator.
In the form shown in Fig. 5 the partitions 12 are not corrugated as hereinbefore described, the several projections 1e114 and 15'l5 on each partition are formed substantially as hereinbefore described but are preferably slightly larger than in the radiators having corrugated partitions so that when air is passing through between the partitions in the direction indicated in the drawings the several projections tend to direct the air both against the surfaces of the adjacent partition and into the spaces be tween the tubes, thus operating in substantially similar manner to the form hereinbefore described.
In Fig. 6 the several partitions 16 are shown corrugated substantially as hereinbefore described but no projections are provided and while in practice it is found that the form of my device shown in Figs. 5 and G are considerably more eflicient than where a plane flat partition is employed, the form shown in Figs. 1, i2 and '3 is preferable as attaining the highest efficiency and while I have merely shown substantially continuous partitions with corrugations and projections to direct the air passing between the tubes.
It is obvious that various immaterial modifications may be made in my device whereby'the air currents are brought into intimate contact with the radiating surfaces and the formation of partially heated insulating strata of air adjacent such surfaces may be prevented, 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.
\Vhat I claim as new and desire to secure by Letters Patent is: l
A radiator, comprising suitable headers and a plurality of substantially vertical water conducting tubes, a plurality of trans versely corrugated plates interposed between the headers and surrounding the tubes, each plate having a plurality of alternately upwardly and downwardly struckup air defleeting projections positioned adjacent the tubes and arranged at an angle lateral to the normal direction of the air passing through the plates.
In testimony whereof, I have hereunto signed my name in the presence of two sub scribing witnesses.
