This invention 'relates vto means for. ltrans- -erring :heat .from oneyphysical medlum to another and ymore especially to .devices commonly fknown .as radiators such Vlas used, `.for
instance, in connection with -internal comibustion engines and the like.v
Thefmain objects of the invention are to .provide a .complete combined `radiator and circulating unit of .improved .formand construction; `to provide a radiator device inl such Vform and adapted ifor'such operation -as to increase the heat transfer eiect per .unit
of water or other .heat carrying medium.; to provide a long .travel path both for the water and for ztheV-air Yin a radiator .of this kind;
to provide for movement of these mediain Y mutually opposite directions substantially;
to utilize vthe natural draft eiiect ofga column of warm air .for .supplementing'the .fan
. series stage form. Theseand other 'objects Y fao effect; to provide such a vradiator adapted for heavy duty zon a minimum supply .of water; to provide such la device as a whole 'in compact and unitary form `adapted for "minimum .ground .space consistent with -accessibility and convenience 1n control and upkeep; and vto provide a vvertical unit ra diator of the character described in upright will more fully appear.
The following is a brief description of a 'vertical unit type .of radiator 'with a fan combined therewith. This was developed primarily for installation `in the -oil .fields where there lare many engines operating lfrom y3.0 'to 80 H; P. .in pumpingfplants, .and for.
other Vuses where ,a thermo-Siphon system vis used in connection. with a water. tank placed either on the roof or on a trestle adjacent thereto. While athermo-siphon system operatesreasonably well .under ordinary conditions on a pumping well, when loperated `under a heavy load themotor .usually'runs `very hot. Furthermore, :when moving the `installations from one .location to Yanother it is necessary :to dismantle 4the wooden .tanks which are commonly used .for water storage K purposes, and this `occasions y'serious delay,
which the present invention overcomes. The
v.radiator herein described and claimed is :designed on ythe counter-current `principle `room also 'being indicated by -dot and 'dash whereby fthe hottest fwater'comes in contact withlthe .hottest `air when the latter is leavzing `:the radiator, and the cooled water about Ito Vleave vthe radiator vcomes :in contact with the'coldest incoming air. The radiator isfdesigned Eto obtain primarily a longer Itravel .of the Waterfthan is'usual inthe lordinary square ftype of radiator, and also to yobtain a longer travel of the air than is1usual, 4and to reduceithe size ofthe fan l'required and the 'power consumed. In thecasenof a small vertical unit for a 40 P. engine the radiator is 24 wide and 40 high, and lthe ifan 20 :in diameter requiring approximately 1% H. P., whereas ythe-usual type of radiatorwould be 30 :square and would use a 26 fan, requiring aboutf21/ H. P.
rEhe .apparatus 2hereshown uses `a blower ...type .of fan,'whereasra suction type'l of fan lhas usuallylbe'en used heretofore. .This fan drives 70 vthe air through the lower portion ofthe radiator and through 'a she'etmetal frontconnecation and .through ithe upper portion lof the radiator. Ashallowftyp'e of corefis used, fand henc'etmore eiicientresu'lts areobtained .from the air delivered. Furthermore by connecting astack throughthe vroof tothe discharge casing, not only does the stackassist-the small lsize fan in pulling 'the air `through the 'radiyzator core, but in rcold weather under ,some S0 v:conditions Ait lis'practicable to remove the belt from .the 'fan pulley A.and use only natural .draft for lthe purpose.
f An illustrative embodiment of thisinvention :is shownlby the accompanying drawings B5 .in which shown vin Fig.` v3, as viewed from the left with the pump vand its supporting plate omitted. m
`diagonally adjacent oriV the floor,
'In the construction shown in the drawings, referringfirst to Figs. 1 and 2, the improved radiator unit 1' and the internal combustion engine 2 arel built separately and are mounted They are 'Y connectedl by pipes 3 and Il for circulation of 'Water throughthe engine jacket and the 'ra- Carries diator as will be apparent. VPipe '3 cooled water frointhe base of theradiator to the -lowerpartqof the-engine jacket, and pipe lcarries hot waterfrom the upper part of the jacket to the top of the radiator.A VVAir,
for .cooling the radiator is admitted intherv A lower Vpart at, under forced drafti; Iytpassestf* directly through the lowermost stage 6 of the The water is drivenff'rom pump 17 through the upper section of pipe 3 to the jacket of engine2, thence through pipe 4 to entrance 4 at the top of theradiator, thence down through thecore sections 21 past stages 8 6 to the exitV 3 at the bottom of the radif ator, andthence'through' the lower section of radiator, thence upward throughthefront casing vmember 7 thence-backward. through the second stage 8k of theradiator to 4the discharge chamber 9 from' wliencethe aire in its heated state ris discharged upward through the connector 10Vinto v the stack 11 leading upward throughthe roof tothe openair. *In
. `order to provideforthe escape of steam from the radiator 1 a vent itubey 12 isfprovidedV a limited extrasupply ofwwaterto replace evaporation or otherloss'.Y` r
' lnorde'rto provide a positive/and .forced tvdraft intothe radiator intake 5, a fan lrof the blower type is mountedthereinandV operated by connection `to the engine, the belt 141 ,being carried bythe engine.v ily wheelandV the relatively small VKpullej,7 16 on the fan shaft 13. Afrotary pump 17 is: connected v'in the I" ,water circuit' as-.in thelpipe 3. This pumpis f driven'by abelt 1 8' carried'on the pump pulley 19 andfon theouter edge offan pulley "16, which is grooved at 16 to .receive the narrow -A `V-belt 1'8. The pump rests -on across plate Ifr'lhe"radialtor a whole, referring now to Figs. 3 and 4, comprises mainly a rec-l tangular frame'20, a plurality/of interchanger./andsa-id members Z, 9and 13;, Theframe 2O includes a, pairY ofl uprightiside-bars'f23,`aitop manifold 24 and a'y bottom irnanifold 25,foot f therefor also extending togthe open air. yThis tube also serves as a stand-.pipe reservoirfor Apipe 3 back to the pump.

:The initial cost of the outfit as a whole is also minimized due to the smaller permissible size ofiinit resulting from a vmore intensive use of given volumes of air and water and a wider range of the'temperature cycle for the water. It is readilyfinstalled in .connection vwith ai plant already.` inV use and withoutV disturbing the setting oftheold engine. It will be noted that the wat-er 'connection from the engineruns into `the top cast iron sectionfior'manifold of the radiator, and that directly. overiv sameis alarge vent pipe con- ;nection, which in the 'event ofany steam developing I dueY to overload ywillv immediately vent the radiator Vthrough the roof instead of vthrough the usual overiiow connection. Y This vent'pipe'alsoserves the'purpose of an .eX- --pansion tanlrfwhen the volume of water is inthrought-he overflow l.pipe'on the ordinary type of radiator. Adjacent to the vent pipe :is an overiiow filler connection 28 and loosening the plugin this connection will always in'- dicatewliether or not the system is filled with able upright core,V sections 21, a fan casing.22,-
' the sections 21 connecting said manifolds are correspondingly long, thusproviding ,for the s'eriesls'ta'ge ,vertical -unit operation, air Vpassing through the sections; reversely at the .r55'top'and bottom respectively, as Vindicated by ,the arrows.
