RADIATOR Filed July 27. 1932 INVENTUR ATTORNEY Patented Aug. 8, '1933 I RADIATOR Fred M. Young, Racine, Wis.
Application July 27, 1932. Serial No. 624,972-
2 Claims.
This invention relates to certain new and useful improvements in radiators, and refers more particularly to radiator core units for concealed radiation.
Radiator core units for this type of radiation comprise a plurality of tubes through which the heating medium circulates and a multiplicity of thin sheet metal fins mounted on the tubes to effect an eflicient heat transfer from the tubes to the air which is circulated through the unit in any suitable manner.
The radiating fins, being formed of very thin gage metal are easily bent and therefore subject to substantial injury unless protected, especially during the period of installation when the units are apt to be roughly handled.
It is therefore an object of this invention to provide a radiator core unit having provision for protecting the fins against deformation by contact with external objects. 7
A more specific object of this invention is to I provide a protecting outer shell including side walls which extend across the opposite-side marginal edges or the fins and are so mounted that expansion and contraction thereof does not impart disturbing stresses to the fins.
Another object of this invention is to provide a protection for the endmost fins ef the core unit against the intensive heat which is applied during the brazing of the usual headers to the ends of the tubes.
With the above and other objects in view which will appear as the description proceeds,
' this invention residesin the novel construction,
combination and arrangement of parts substantially as hereinafter described and more partiedlarly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.
In the accompanying drawing, one complete example of the physical emboent of this invention is illustrated constructed according to the best mode so far devised for thepractical ing the manner in which the headers are secured to the unit. Referring now more particularly to the accompanying drawing, the numerals 4, 5, 6 and '7 represent the tubes of the core unit which extend longitudinally throughout its entire length. These tubes, as best illustrated in- Figure 3, are preferably of elliptical cross section and the ends thereof aresecured to headers 8.
Mounted on the tubes is a plurality of thin gage sheet metal fins 9 crimped vertically as at 10 between adjacent tubes to strengthen the same. The fins 8 are assembled on the tubes and secured thereto in any suitable manner and are preferably of rectangular shape. The exposed edges of the fins are protected against damage by a pair of side plates 11 which e'xtendalong the entire length of the core unit and are slightly wider than the fins to project above and beneath the same. These side plates 11 are held in proper position by being attached to end plates 12 and an intermediate cross plate 13. The intermediate cross plate 13 is preferably located centrally of the length of the core except in instances where the core is of excessive length where several intermediate cross plates may be employed. 1
The end plates and the cross plate 13 are suitably. apertured to receive the tubes 4, 5, 6 and 7 and have substantially the same area as the line 8 with their marginal end edges lying in the plane of the adjacent ends of the fins.
Extended from the ends of the plates 12 and 13 are tangs 14 which are received in suitable apertures 15 in the side plates and then struck over, to hold the side plates in position in a simple but emcient manner. The apertures 15 through which thetangs 14 project are slightly wider than the tangs to facilitate the application of the side plates thereto.
It is observed that this manner of mounting the side plates permits independent movement, on the part of the side plates with respect to. the fins, efiected by expansion and contraction so that any such movement of the side plates does not disturb the fins and does not set up undesirable strains in the core unit. 1 Further protection against internal stresses resulting from expansion and contraction of the various elements of the unit, and particularly be tween the side walls and the radiating fins is obviated by reason of the fact that the cross plates 12 and 13 being directly attached to the tubes'and having substantially the same area as no the fins, expand and contract practically in her" mony with the expansion and contraction of the fins. Any diiiferentiel in expansion of the cross pistes end fins is sccommodsted by the vertical crimes or needs is in the fins which set suhsten tie-11y as expansion joints. As 9. result, the side pistes 1.1 me be said to breathe with the expansion and; contraction of the moisten" unit.
The enei plates 12 further serve to protect the encirnost fins against the encwsive nest incidental to farming the tube enzis to the headers, the end; pistes being of snostsntisi weight to ebsoflo the heat and keep it from the From the foregoing description taken in conneotion with the accompanying drawing, it will be resoily apparent to those skilled in the to which an invention of the character described e'gxperteins, that this invention efiords a novel with the tube end extending therebeyond; sine pistes extending; ocross the opposite marginal neonate edges of the fins, trsnsverse pistes entries by the tube snti connected with the miss to hold the some in position adjacent to the sold opposite msminsl edges of the fins, tint independent-is thereof said transverse pistes t e-,- ing formed of sheet metal ens: expanding and contracting sufostentiaily in lion-many with the expansion and contraction of the fins, and compensating mesns formed in the fins to compen sste for any differential m expansion and contraction between the transverse. pistes snot fins,
