Application filed February This invention relates to radiators for in? vteriial combustion engines and proposes a novel core construction which is designedto improve the structural characteristics 'of the radiator as well as to enhance its efficiency as a heat dissipatiiig unit. l
One of the objects of the invention is the provision of water tubes arranged in adjacency and formed to encompass the maX- imuiii amount of air at the forwardfend of the radiator and to deflect it `against the in' as the air becomes warmer so that the thick#l ness of the film of circulating liquid to be cooled is direct-ly proportioned at any point to the rate of heat exchange.
A further object of the invention is the-A provision of a core comprising vertical tubes each extendingin a widthV direction sub!v stantially the full thickness of the core, the front of said tubebeing formed as an edge in order to oppose minimum resistance to the air and to vpermit a maximum quantity of air topass through said radiator, the walls of said'tube toward the rear being corrugated to provide for expansion should the cooling liquid therein contained become frozen.v
A still further object of the invention isil the relative arrangement of adjacent tubes to forni an air conduit diverging from an intermediate point both forwardly and rearwardly and having the rear walls thereof provided with mea-ns for deflecting thev current of air flowing through said ,conduit in a zigzag direction from one side to the other to ensure complete' and continuous renewal of the air along the surfaces of said tubes.
With the above and other objects in view,
my invention consists in the improved ra-vv 7, 1923. serial No. 617,595.l i
Vas will be robvious to those skilled in the,v
art to which my invention relates.
- Inthe drawings accompanying and forming a part of this specification, and ,l
wherein the preferred embodiment of my invention is illustrated: Y
Figure l is a front elevationwofV my im proved radiator.
Figure 2 is' across section ofa portion thereof, on an enlarged scale', taken along the line 2-2 of Figure V1.
Figure 3 is a side sectional view taken along tlieline 3*-3 of Figure l.
Figure 4 is a perspective view of a p0rtion of one of the tubes and the spacers associated therewith.
Referring now in detail to the several ligures, the numerals l and 2 represent,l respectively, the upper and lower headers ofthe radiator, thefformer beingatank of considerable capacity, as shown in Figure 3. Conduits 4 and 5 lead respectively, from the upper and lower headers' of the radiator to the cylinder jacket of the internal combustion engine, not shown. The upper header is providedwth a filling opening 6, and an overflow pipe 7 originates iny said opening and passes in a water-tight'manner through an aperture in the header 1, as shown at 8, and downwardly closely adjacent the rearface of thecore, the lower end of said overiiow pipe terminating below the radiator. The features thus far enumerated are conventional and, in themselves form part of the'present invention only broadly in combination with the structurenow tobe described. The upper and lowerheaders are joined to the opposite ends of aseries of vertical tubes 10, with which they are in communication. These tubes are soldered to the adjacent faces `of the upper and lower edge'frll and rear edge 12, with an inter' mediate portionwhich is widest in cross section at a point adjacent the front of the tube as shown atgl. That portion of the n'alls of said tube which lies forwardly of the widest part 13 is smooth whilethat por# Vtion to the rear of the widest part is formed The tubes are with Vertical corrugations. arrangedv` in paifallelisrnbetween thel upperL and lower headers, as shown inFigiirelQ; from which figure it will be noted that the rear vportions of the'tubesar'e disposed anguiar-ly to the forward portions so that air sarily forin'ed, the saine" being preferably entering 'between adjacentr tubes 'longitud nally of the direction of inotion of the Vehicle upon which the r-adiatoris Inou'nted, isY
