Description
June 12, 1951 w. POWELL RADIATOR Filed Aug. 5, 1948 William L. Powell IN VEN TOR.
BY W M4,
Patented June '12, 1951 UNITED STATES PATENT OFFICE RADIATOR William L. Powell, Kissimmee, Fla. Application August 5,1948, Serial No. 42,715
Thisv invention relates generally to heat exchangers and more particularly to a radiator of the type employed in automotive vehicles for air cooling the water in the water jacket of the engme.
A primary object of this invention is to provide a radiator with a lower tank having a sediment bowl and a bottom wall sloping toward said bowl, and also providing vertical tubes having tapered bores between the top and lower headers of the radiator and with the greater diametered end of the tube being disposed toward the lower header tank, so that sediment and material boiled out of water in the radiator is made free to gravitate downwardly through the tapered vertical tubes, along the sloping bottom wall of the lower header tank and into the sediment bowl.
Another object of this invention is to provide a sediment bowl of flexible material and removably secured on the lower tank by means of a split clamp of the type ordinarily known as hose clamps.
Still another object of this invention is to provide, in conjunction with the above mentioned tapered tubes, a plurality of substantially horizontal fins, each fin having a plurality of apertures to receive said tubes, and the difierent fins having differently sized apertures to fit different portions of said tubes, whereby assembly of the radiator is facilitated.
With these and other objects which will appear hereinafter as this description proceeds, this invention resides in certain novel features of construction, combination and arrangement of elements and portions as will be hereinafter described in detail in the specification, particularly pointed out in the appended claim, and illustrated in. the accompanying drawings which form a material part of this application, and in which:
Figure 1 is an elevational view of a radiator constructed according to this invention, a portion of the lower header tank, sediment bowl, and pipe fitting therefor being broken away and these parts being shown in vertical section to facilitate the illustration of this invention;
Figure 2 is a horizontal transverse sectional view, taken on the line 2-2 in Figure l; and
Figure 3 is a vertical fragmentary sectional view, taken substantially upon the line 3-3 in Figure 2.
Similar characters of reference designate similar or identical elements and portions throughout the specification and throughout the several views in the drawing.
1 Claim. (Cl. 257125) Referring now to the drawing in detail, this invention includes a radiator comprising a top header tank, a bottom header tank, indicated at H] and 12, respectively, the top header tank having a filler tube I4 and a cooling Water outlet 16 and a horizontal attachment flange I8. This structure is conventional, as is the provision of an apertured top plate 20 which will be soldered or otherwise secured to the flange l8 and to outturned flanges 22 on side plates 24 associated according to conventional practice with the core portion of the radiator.
The side plate 24 is provided in duplicate and flanges 26 of the side plates are secured to an aperturecl bottom plate 28, which is in turn secured, as by soldering, to a flange 30 on the bottom header tank [2. A water inlet tube 32 will be incorporated with this lower header tank l2 and this tank will have a sloping bottom wall 34, with a sediment bowl attachment pipe fitting 35 integral with the same near the lowest point thereof. A sediment bowl 38, preferably constructed of resilient material, is secured on the pipe fitting 36 by a split hose clamp 40.
The core portion of the radiator includes a plurality of horizontally spaced, vertically extending tubes 42 which are tapered'throughout their lengths, the larger ends of the bores of the tubes being connected to the bottom header tank [2, and the smaller ends of these tubes being secured to the top header tank l0, so that communication is provided between the two tanks according to conventional practice, except that the tapering of the tubes facilitates the downward movement therethrough of sediment and material boiled out of the water in the radiator, thus helping materially to prevent the clogging of the tubes at their upper ends, where such clogging ordinarily is encountered in radiators of completely conventional type.
It should be very carefully noted that the tapering of the tubes, the sloping of the bottom wall 34 of the tank l2, and provision of the sediment bowl 38 are all coasting elements in a radiator constructed with a View to minimizing the tendency to clog due to accumulation of material at the upper ends of the tubes.
A plurality of substantially horizontally disposed fins 44, each comprising a thin apertured plate, are provided to complete the construction of this radiator. Each fin has a plurality of apertures to receive said tubes, and the different fins have differently sized apertures to fit different portions of the tubes. Since the apertures in any one fin will be uniform in size, it follows that selection of different fins according to the size of apertures therein will facilitate the temporary location of the fins on the tubes during the assembly of the radiator, the fins being rigidly secured, as by soldering the tubes to the fins and/or soldering the fins to the side plates 24.
The operation of this invention will be clearly understood from a consideration of the foregoing description of the mechanical details of thi invention, taken in conjunction with the drawings and the above recitation of objects.
Variation in form and proportionment of the various elements may be resorted to without departure from the spirit of the invention, and the scope of the invention should be determined only as limited by a proper interpretation of the following claim.
Having described the invention, what is claimed as new is.
A radiator comprising a top header tank, a bottom header tank, a plurality of tubes communicating with and extending between said tanks, said tubes having tapered bores with the larger ends of the bores at the bottom, and a removable sediment bowl operatively mounted on REFERENCES CITED The following references are of record in the file of this patent:
