TRANSFORMER RADIATOR.
Application filed. December 21, 1920. Serial No. @2355.
My invention relates to radiators, and it has particular relation to radiators adapted for utilization with transformer cooling systems.
One of the objects of my invention is to provide a radiator of the character described having a relatively large radiating surface, as compared with the space occupied thereby.
Another object is to provide a transformer radiator having a compact arrangement of the various elements and one that may readily be assembled and disassembled with a minimum of time and labor.
Heretofore, certain types of transformer radiators have been constructed of a pluor M1 in UN! rality of separate and independent radiators arranged radially around the periphery of a transformer tank. These radiators generally comprise a plurality of vertically extending and communicating unitsarranged in spaced and parallel relation with eaclrother. Each of the units have, heretofore, been constructed with substantially the same crosssectional dimensions. When a plurality of complete radiators comprising units of such dimensions were arranged in position around the periphery of a transformer tank, the edges of the respective units of each adjacent radiator lay in diverging planes.
Such a construction was undesirable for the reason that considerable available space between the adjacent radiators was unoccupied. This unoccupied space increase-d outwardly as the space defined by the sides diverged, and was considerably greater than was necessary for an effective circulation of air.
According to my invention, I form the separate units of each radiator with the cross-sectional areas thereof having different transverse dimensions. When the units so formed are assembled with the size of the units progressivelv increasing outwardly having a plurality of radiators mounted thereon constructed in accordance with my invention.
Fig. 2 is a fragmentary view, partly in elevation and partly in vertical section, of a transformer tank and radiators.
Referring to the drawings, 1 indicates a transformer tank having plurality of radially extending radiator elements 2, mounted around the periphery thereof by means of couplings 3. The radiators each comprise a plurality of separately formed communieating units or cells l arranged in spaced and parallel relation.
The side walls 5 of each of the units are preferably formed of sheet metal blanks pressed into the desired shape and welded or otherwise suitably secured together. Each of the side walls 5 may be provided with a plurality of vertically extending reinforcing indentations 6. The upper and lower extremities of each of the side walls 5 are preferably formed with extensions 7 having extruded portions 8 and apertures 9 adapted to register with the corresponding extrusions and apertures of an adjacent unit to effect communication therebetween.
For convenience in manufacture, the units L are preferably arranged in groups, the major dimensions of the cross-sectional areas of the units of each respective group being SUbSi antially the same. The traniiiversc dimensions of the cross-sectional areas of the units of each group greater, however, than those the adjacent group nearest the center. That is to say, the confrontin edges of each pair of units of the adjacent radiators lie substantially in parallel planes, the distance between the innermost unit determining the distance between the adjacent radiators.
The units may be formed with ever increasing major dimensions with respect to the cross-sectional areas thereof. Such construction, however, requires dies or other suitable forming tools of correspondingly varying sizes. It is, therefore, preferred to construct a radiator of group units, the units of each group having the same size and with the edges of the respective groups arranged in spaced relation, as above set forth.
The construction of a radiator of grouped units of the same size, does not materially afiect the distance between adjacent radiators, as the difierence in size of the units of the different groups is so slight as to make a relatively small step.
