1933- R. s. WENTWORTH RADIATOR.

between the two ends.
for instance, eleven inches high, the upper seven inches have a very low efiiciency as compared with the bottom four inches. As shown by the chart, at eleven inches a unit of surface functions at only of the normal rating. From this it is evident that an ideal radiator must provide for a very short air travel in contact with the radiator, but there must be a large surface with which the air can initially contact.
My invention contemplates the use of a section, the mid portion of which is out of horizontal alinement with the end portions, whereby the barrel portion of the section is no longer than it is where the barrel extends in a straight line More especially, the invention contemplates arching the section into the form of a V, or a U, or an inverted V, or an inverted U, providing in eifect two barrels in the same space where only one has been used before,
sloping fin section of the type disclosed in my said copending applications and which is marked G. The distance from the center of the nipple port at the bottom of this section to the center of the nipple port at the top of this section may,
for the purpose of illustration, be assumed to be 10 inches. The transverse thickness of the barrel from the upper edge to the lower edge is four inches. This means that the air rising up through the flue A has to pass through the radiator G and in doing so flows in contact with the radiatorfor a distance slightly in excess of four inches. i
In the same figure I have shown in full lines a section embodying the present invention and markedI-L This section is shown as being in the form of an inverted V, and the thickness through each barrel is just half the transverse thickness through the barrel G.
Assuming the same spacing of fins on the two sections, the section I-I will have just about the same area as the section G. In the case of section G,-however, the air remains in contact with the radiator through four inches of travel, whereas in section H the air is in contact with the radiator only during two inches of travel.
Referring to Figure 8, it will be seen that each unit of area on the section I-I will function at a much higher eificiency than each unit of area on the section 'G. This means that in the improved section II there will be a greater rate of heat transfer per pound of metal in the radiator than there is in the section G. a
My-invention affords, therefore,.a greater efficiency per pound of metal or per unit of surface than has been heretofore obtainable. In Figure '7 I have shown the sections G and H as being of I the same, height and having, therefore, substantially the same surface area. Because, however, of'the greater efficiency of the V-shaped type, the
section H may actually be made shorter than the section G in vertical height and consequently lighter. By makingthe sections shorter a still greater advantage obtains because there is a. greater mean effective draft head in the flue A several of these sections securedtogether in faceto-face relation as disclosed in my said copending application Serial No. 513,883. At the lowerend of each of the barrels 6 and 2 is a header portion 9, the header. portions 9 also having nipple ports therein.
On each of the barrels 6 and '7 are laterally projecting sloping fins 10. The fins on the barrels'slope away. from each other,'i. e., outwardly and upwardly from the center of the V. The fins are set at an angle to both the longitudinal and transverse axes of the legs or barrels, the angles of these fins preferably being within therange specified in my said copending applications, 1. e., at an angle ranging between 27 andp45. to the plane of the transverse axis of the barrel, and preferably at an angle of 33 with respect thereto. -The section shown'in this figure corresponds to the section H illustrated in Figure 7. The cold air entering the enclosure flows up into the crotch of the V, escaping to the upper sides of the ra diator by flowing through the channels between thefins. p
In Figure 2 I have shown a section similar to Figure 1 and have used corresponding reference numerals to indicate the corresponding parts. The only difference, however, is that the section is inverted with respect to the section shown in Figure 1-.
'In the arrangement shown in Figure 3 the sec.- tion is also V-shaped and may be inverted or upright. It has two legs 11 and 12 and differs from the arrangement shown in Figure 1 only in the fact that no header 8 is provided at the apex of the section. Sections of this type can be used in certain steam heating installations.
The arrangement shown in Figure 4 provides a radiator having diverging barre- ls 13 and 14, which barrels are provided with the sloping fins as described. The barrels l3 and 14 may comprise single straight sections similar to the sections G and similar-to the sections disclosed in my-said copending applications. Instead of being used in the single arrangement as disclosed in my said applications, they are arranged in downwardly diverging pairs as shown. A special'end fitting 15 at each end of the radiator thus fabricated establishes communication between all of the sections. tutes the subject matter of a copending application in which it is specifically described and claimed, and which is Serial No. 601,325, filed March 26, 1932. Y
The advantage of the arrangement shown in Figure 4 is that it permits the use of the single straight sections disclosed in my'said copending This special end fitting l5 constiapplications, and the barrels 13 and 14 can be header for the two diverging legs and conseprovided at the top of the bend in the U, as indicated at 19, or the header at this point can be dispensed with similar-to the arrangement shown in Figure 3. The lower ends of the barrels 17 and 18 are provided with headers 20. The section shown in Figure 5 may of course be inverted to a position corresponding to the position of the sec-, tion shown-in Figure 2. This, 'in effect, is secured byproviding a section substantially in the form of an arch which is either upright or inverted.
Obviously,,various otherchanges and modifications may beimade in the particular construction and disposition of various elements of the section withoutdeparting from the spirit of my invention; As explained, the invention has the advantage of providing a section in. which every unit of surface functions at an efficiency much higher than has been obtainable in any other type of radiator with which I am familiar.
