Description
S. C. QUAGLIANA RADIATOR CORE Filed Oct. 17, 1922 lt atented Ed, 1925..
RADIATOR Application filed. October 17, 1&22.
To all whom it may concern:
Be it known that I, SAMUEL C. QUAGLIANA, a citizen of the United States, residing at ldufi alo, in the county of Erie and Stateof New York, have invented new and useful Improvements in Radiator Cores, of which the following is a specification.
This invention relates to a core for radiators oi the type in which the water tubes are made of opposing strips of sheet metal and the air passages are formed by means of radiating fins arranged between adjacent water tubes, said tubes and fins being provided with co-operating members to complete the air tubes.
It is the object of this invention to provide a radiator of this character in which the walls of the water tubes and the radiating fins are more securely interlocked, and thus materially increase the strength and durability of the core.
In the accompanying drawings: Figure 1 is a fragmentary sectional. elevation of a radiator having a core embodying my invention. Figure 2 is an enlarged view showing the interlocked joint between a radiating fin and two pleats of opposing water tubes. Figure 3 is a horizontal section taken on line 33, Fig. 1. Figure is a vertical section taken on line l l, Fig. 1. Figures 5 and 6 are fragmentary sectional perspective views of one of the radiating fins and a pleated wall of one of the water tubes. Figure 7 is a fragmentary elevation of a radiator core showing a modified form of my invention.
Similar characters of reference indicate corresponding parts throughout the several views.
In its general organization, the radiator shown in the drawings as embodying my invention comprises a water box or header 10, a plurality of upright water tubes 11 communicating at their upper ends with said water box, and a plurality of horizontal air passages 12 arranged between adjacent water tubes.
Each of the water tubes is constructed of two strips of sheet metal to form two upright walls 13, 13, which are arranged side by side but spaced apart to form the water tube between the same. The vertical edges of the walls are ol'l'set toward each other, as shown at 14, which offsets of companion walls are connected by solder so as to close COR-E.
Serial No. 595,063.
the joint between them and render the same water tight.
fit intervals each of the water tube walls is provided with a laterally projecting horizontal pleat. so that the pleats on the opposing walls of adjacent tubes project toward each other. Each of the pleats is formed by doubling the metal of the wall upon itself at regular distances apart. In the construction shown in Figs. 1, 2, and 6, each of these pleats has an enlarged head 15 at its free end and a reduced neck 16 connecting this head with the adjacent sections of the wall formed integrally therewith from a single strip of sheet metal.
Between every two adjacent water tubes an upright radiating fin is arranged which is constructed of a strip of sheet metal so as to form a plurality of webs 17 arranged in a vertical row, and a plurality of S- shaped bends 18 each of which forms two oppositely opening concave seats, the inner part 19 oi earh seat forming an enlarged socket and the outer part 20 forming a reduced throat. The socket of each seat on each i i-shaped bend receives the enlarged head of one of the walls of a water tube and the throat of each socket receives the reduced neck of the respective pleat, thereby firmly interlocking each pleat with the water tube walls on opposite sides of the latter and forming with the same two upright rows of horizontal air passages between every adjacent two water tubes.
In addition to being thus mechanically interlocked, each fin and the pleats of the water tube walls on opposite sides of the same may be secured together by soldering, thus holding these members against lengthwise displacement relatively to each other.
In the modified form of my invention shown in Fig. 7, the concave seats 21 of the S-ehaped bends in the fin are each of the same width throughout the depth of the same and the free ends 22 of the wall pleats 23 seated in the same are also of the same thickness, in which case these members when engaged are not interlocked in a lateral direction and therefore require soldering for holding them together.
In both the structures shown in Figs. 1-6 and 7, the central part of each 5-shaped bend of the radiating fins is engaged on its. opposite sides by the free ends of the pleats of the opposing walls of two adjacent Water tubes so as to form two upright rows of air passages each of which is substantially square in cross section and horizontally in line with the air passage on the opposite side of the intervening web of the radiating fin, thereby simulating the well known square tube radiator so much in public favor.
Aside from being attractive in appearance, this radiator also has greater strength on account ot the firm connection which is secured between the pleats overlapping central parts of the Sshaped bends in the fins.
I claim as my invention:
1. A radiator core comprising a plurality of water tubes and a plurality of air passages arranged between said water passages, each of said water tubes having longitudinal walls which are provided with laterally projecting pleats, the opposing walls of adjacent tubes having their pleats projecting toward each other, and a radiating tin arranged between adjacent tubes and having a pin 'ality of longitudinal webs which are arranged opposite the spaces be tween the pleats of adjacent tubes and an s-shaped bend connecting adjacent webs and the concave side of one turn of said bend receiving the free end of a pleat on the wall of one tube and the concave side of the other turn of said bend receiving the free end of a pleat on the opposing wall of the adjacent tube, the concave sides of said turns being out of line with each other and the pleats of said tubes engaging therewith being also out of line a corresponding extent.
2. A radiator core comprising a plurality of water tubes and a plurality of air passages arranged between said water passages, each of said water tubes having longitudinal walls which are provided with laterally projecting pleats. the opposing walls of adjacent tubes having their pleats projecting toward each other, each pleat having an enlarged head at its free end and a reduced neck connecting said head with the adjacent part of the respective wall, and a radiating fin arranged between adjacent tubes and having a plurality of longitudinal webs which are arranged opposite the spaces be tween the pleats of adjacent tubes and an S-shaped bend connecting adjacent webs and the concave side of one turn of said bend receiving the tree end of a pleat on the .wall of one tube and the concave side of the other turn of said bend receiving the free end of a pleat on the opposing wall of the adjacent tube.
3. A radiator core comprising a plurality of water tubes and a plurality of air passages arranged between said water passages, each of said ater tubes having longitudinal walls which are provided with laterally projecting pleats, the opposing walls of adjacent tubes having their pleats projecting toward each other, and a ra diating fin arranged between adjacent tubes andhaving a plurality of longitudinal webs which are arrangedopposite the spaces between the pleats otadjacent tubes and an S-shaped bend connecting adjacent webs and forming two oppositely opening concave seats, each seat having a wide inner part or socket which receives the head of one pleat and a narrow outer part or throat which receives the neck of the respective pleat.
