10 Claims.
The invention relates generally to heat radiating units and` primarily has for anV object. to provide a novel form of such. unit in which water isheated and circulated in a highly efcient manner andthe heat of the water effectively transferred by radiation` to the surrounding atmosphere.
In its more detailed nature the invention resides inthe provision of a novel heat radiating unit including a water tank, a. heating element supporting water distributing body,. water tubesfor carrying heated water from the distributor body to the water tank and cooperating radiating fins for effectively radiating the heat of the water, a. duct of novel shape for delivering water from a low point in the tank to the distributor body, and an electrical heating element mounted in a novel manner in said duct, allbeing cooperatively arranged whereby a very high degree of heat radiatingl eiliciency isA assured The invention further resides in the provision of means for assuring against use of an electrical heating element having a hea-ting capacity in excess of that desired for cooperation with the radiating surface area presented' by a particular design of heat radiating unit.
With these and other objects` in vievvlwhichY will more fully appear; the nature of the inverntion will be more clearly understood by following the description, the appended claims,l and the several views illustrated in the: accompanying drawings. l
Inthe drawings:-
Figure 1 is a front elevation of4 my improved heat radiating unit,. parts being shown in: longitudinal section.
Figure 2 is a vertical cross section taken. on thev line 2-2 on Figure 1.`
Figure 3 is a right hand end view of they unit, 4:0V the electrical heating element being removed.
Figure 47 is an inverted plan viewv of the unit.
Figure 5is a detail perspective view of. the electrical heating element.
Like reference numerals designate correspondingf partsthroughout the several figures of the drawmgs.
In the practical use of my invention my iVm-- proved heat radiating unit is supported in and encased by any suitable design of cabinet or r housing but sincei such cabinets arewell known:
in theart detail disclosure of the encasing struc-- ture is `thought to beinmecessary.' The end walls of: such a structure which serve tol support my improved! unitare indicated. however ands gener- V5v5 ally designated 5.
19.34, Serial No. 718,298
(Cl` 21'9-38)y One end wall 5 of the cabinet or housing has secured thereto by welding or otherwise a bracket angle 6, and thewall 5` at the opposite end oi the cabinet is equipped withv a. cross channel member 7 similarly secured thereto by welding.. My improved unit, removably supported by the elements 6 and '7,4 includes a, water tank generally designated 8 and preferably composed. of indi.- vidualcopper bronze casting sections 9 and 10. The section 10. comprises a flat cover plate portion 11 and a dished or shell-like enlargement 12, and the whole of the section. 9' is inthe nature of an open rectangular shell, both sections being equipped with complementary flanges 13 which.k are welded together to complete the tank. The lower portion` of the tank thus formed` is in the nature of a relatively narrow vertically disposed water chamber and, because of the enlarged shell portion 12 of the section 10f, the upper portion of the tank forms a relatively spacious Water head chamber.
Ay relief valve of any improved. form generally designated 1.4 may be mounted. at a high point in the water tank for the purpose ofV relieving any excess pressure generated during operation of the unit and any suitable means may be provided for administrating a supply of water into the tank such as the simple form of filler-neck indicated at l5. It willv be observed by reference to. Figure 1. of the drawings that the water tank is supported upon the bracket flange 6.
At the opposite end. of. the unit I provide a heatingelement supporting water distributing unit in thenatureof a copper bronze casting gen-V erally designated. 16 and which includes a supporting or seat. portion 17 forming the lower terminusv of` arelatively narrow, rectangular and vertically disposed. heated water distributing chamber 18, andv a lower rela-tively large cross chamber 19 whichcommunicates withI the chamber 1,8 A! bearing extension 20 depends from the portion of thebody inwhich. is formed the chamber 19 and. this extension includes. an inclined` bore 21` and a passageway or duct 22 which affords communicationbetween the interior of! the bore the chamber 19, and through the latter,` with` the chamber 18.v
The extension 20 also includes a, counterbore 23 at its left endf` andA a counterbore 24 at its right end, said right hand end alsov being pro-` videdrwith flange extensions or ears 25 which are thread-tappedat 26to receive clamp screws for apurpose soon to be described.y
Ann upper' series ci copper tubes 27 affords communication between the distributor' body chamthe lower portion of the tank 8 to the distributer body 16. The pipe preferably extends horizon-A tally a short distance to the right of its connection with the water tank and thence extends upwardly to the distributer body at an incline of approximately 8 as indicated at 32, the right hand end of the pipe being received in the coun-- terbore 23 at the left hand end of the distributer body extension 20. The parts thus far described preferably are welded in assembly so as to assure steam tight connections. f
An electrical heating element 33 is removably supported by the vdistributer body extension 20 and extends into the upwardly inclined portion 32 of the pipe 31 as indicated in Figure l.
, The electrical element may be of any approved form well known in the art and in this particular use includes a clamp flange 34 of the same shape as the flanged portion 25 of the distributer body extension and is secured to said extension by clamp screws 35 which pass through holes 36 in the element flange and into the tapsl 26 with which the distributer body extension v flanges are provided; A ring washer 37 is interposed `between clamp anges and by suitably tightening the vscrews. 35 a steam tight mounting ofthe heating element is secured.
It will be observed by reference to Figure l of the drawings that the external diameter ofthe heating element is slightly less than the internal diameter of the pipe 31, 32 and thus a restricted angular space 38 is provided between the element and pipe wall for passage of water, and because of this restricted passage it is possible tok very rapidly heat the water which is circulated by thermo-siphonic action.
In the practical use of my improved heatingy unit it is my intention toy provide a predetermined amount of heat radiating surface in eachv unit and to standardize the parts comprising the unit.l V When a greater heating capacity is demanded the units are constructed in greater lengths and as the radiating `surface is increased heating elements of greater heating capacity must be used. In order to assure against the use in a heating unit of given radiating surface of a heating element of greater capacity than is necessary or desirable, I mount a stop lug 39 in the upwardly inclined portion 32 of the pipe 31 which will prevent insertion into said pipe of a heating element longer, and therefore of greater capacity, than the element designed for use with the particular unit. The removable heating element may include a cap 40.` removably secured In vuse the delivery pipe 31, 32 takes waterv from the lower end of the relatively narrow ver-` tically disposed tank portion and delivers it.'
through the duct 22 into the distributer body chambers 19 and 18 from which it flows into the tubes 28 and 27` back to the tank. While passing through the tubes 27 and 28 the water heated by the element 33 while owing through the restricted space surrounding said element gives up its heat to the radiating fins 29 and therefrom to the surrounding atmosphere. The particular shape and mounting of the delivery pipe 31, 32, the distributer body, the tubes 27 and 28 and ns 29 -provide for a very efficient heating and rapid circulation of the water.
If desired a holddown screw 44 may be utilized for securing the distributer body end of the unit inY its mounting in the cross channel 7.
It is of course to be understood that the details of structure and arrangement of parts may be vvariously changed and modified without departing from the spirit and scope of my invention.
