My inventionrelates to that class of apparatus which is employed for changing temperatures of fluids for Various purposes, and an. object of my invention, amongothers, is the product ionlof apparatus of this sortfwhich is simple in con"- struction and particularly eflicient in the results obtained by its use. I v

One form of a deviceembodying my invention and in the construction and use of which the objects herein set out,`as well as others,y may be attained is .illustrated in the accompanying drawing, in which Figure 1 is a side view of a radiator unit embodying my invention.

Figure 2 is an end view of the same.

Figure 3 is a view in section on a plane denoted by the dotted line 3-3 of Fig. 1.

Figure 4 is an edge View.

Figure 5 is a view in section on a plane denoted by the dotted line 5-5 of Fig. l.

Figure 6 is an isometric View of a fragment of the unit with parts broken away to show construction.

Figure 7 is a detail view on enlarged scale of'a portion of one of the radiating plates.

Figure 8 is a view similar to Fig. 6 but illustrating a'modied form of the invention.

As hereinbefore mentioned my improved aplparatus is for the purpose of changing temperatures by means of fluids Vcirculating through tubes, in some instances the apparatus being employed to lower the temperatures of fluids circulating through such tubes and in other instances the temperatures of fluids owing through the tubes being radiated to lower temperatures outside of the tubes.

A unit comprising a portion of such an apparatus and embodyingmy invention includes a series of radiating plates all of which plates are generally of the same construction,` each plate 9 preferably being of considerable widthA as compared with its length and having notches I0 formed in one edge and preferably evenly spaced from one another.` A flange I I vextends around the border of each notch,'these anges being formed by bending the material outwardly substantially at right angles to the plane of the plate to form the notches and as clearly shown in Fig. 7 of the drawing. These anges may each be unbroken, but I prefer to form them in sections, in the structure shown each flange comprising three pieces, but it willbe understood that 'my invention is not limited in this respect but may consist of any desired number of pieces.

The notches I0 are formed to receive a conducting tube or tubes I2 which vpreferablyare bent to provide parallel lengths separated at distances equal to the distances between the notches IB so that a tube so bent maybe placed in .the

notches in the plates, and as shown in Figs. land 5' 2 'of the drawing. 'The ends I3 of the-1tube are extended for the purpose of connectiontosources of fluid and for the discharge of suchuid whic is circulated through the tubes.

" The flanges Ii are 'for the purpose of properly l0 spacing the conducting plates so that the intervals between the plates will be substantially the same throughout the unit, the flanges .on each plate resting yagainst the surface of the adjoining plate and thereby avoiding any necessity l5 Y for special means for properly spacing the plates,

the anges serving this purpose. As a `means for maintaining uniform spacing ofthe plates between the tubes and the opposite edges of the plates spacers I 4 lare stamped out 20 'from the plate and bent at an angle thereto and y as shown in Fig. 3 of the drawing. These spacers are tapered from a narrow dimension atlthe Vsurface of the plate to a wider dimension at the outer end of the spacer. When the spacers are thus 5 bent into spacing position it will be noted that the wide outer end of each spacer is located opposite the narrow end of the opening in the adjacent plate so that there is no dangerof the spacer entering said opening and the plates are thus 30 properly spaced.

As a means for defiecting currents of air flowing through the unit between the radiating plates curved ribs I5 extend lengthwise of the plates between the two rows of spacers I4 and as shown in Fig. 3 of the drawing. These ribs are'curved crosswise of the plates, and as clearly shown in Fig. 7, and in additionto the function of deflecting currents of air these ribs alsoserve toy stiffen the plates and thereby provide a very rigid 40 structure. Each unit is 'provided at opposite sides with holding plates I6 having flanges II similar to the flanges II hereinbefore described, the flanges I'I encountering the curved portions of the tubes 45 serving to position the set of radiating plates and'thereby to secure such plates in place upon the tubes.v Brackets I8 are formed at the ends of the holding plates for the purpose of securingv the unit as a whole in place for use. 50 The structure shown in Fig. 8 is substantially the same as that hereinbefore described with the exception that the radiating plates I 9 are extended as at 20 beyond the tube I2, Yas shown in Fig. 8, but as in the case of the apparatus rst described the tubev when bent is inserted in place in the unit from one edgeV thereof, being placed in the notches 2l and then slid into position. Any suitable means for securing the tube within the notches in the radiating platesmay be employed as desired.

In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best I embodiment thereof; but I desire to haveit un' A derstood that the device shown is only illustrative and that the inventiongmay be carried out by uses other than those Y 4.
