J. E. n-mlxnrY ET AL RADIATOR Filed NOV. 14, 1954 ATTOWNEY Patented Apr. 7, 1936 UNITED STATES PATENT OFFICE RADIATOR James E. Hunt, Hampton, and Theodore Thornton, Jonesboro, Ga.

1 Claim.

This invention relates to radiators for use in cooling systems of motor vehicle internal combustion engines and has for the primary object the provision of a device of this character which will be inexpensive to manufacture and may be readily repaired and will have maximum cooling capacity for the liquid of the cooling system.

With these and other objects in View, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding o-f our invention, reference is to be had to the following description and accompanying drawing, in which Figure l is a front elevation illustrating a radiator constructed in accordance with our in- Vention.

Figure 2 is a fragmentary sectional view taken in the line 2 2 of Figure 1.

Figure 3 is a fragmentary sectional view taken on the line 3 3 of Figure 1.

Figure 4 is a perspective View illustrating one of the air passage units.

Referring in detail to the drawing, the numeral I indicates a radiator casing of any conventional design and constructed to have the usual water chambers 2 at the upper and lower ends thereof connected by a water passage 3 30 including front and rear walls 4 and 5. The

water gravitates from the upper chamber to the lower chamber by way of the passage 3 and the front and rear walls 4 and 5 of said passage are provided with a plurality of substantially ovalshaped openings in which are removably mounto ed air passage units 6 of substantially tubular shape. The openings of the walls 4 and 5 and units 6 are arranged in superimposed rows, the units of one row being arranged in staggered relation to the units of the row adjacent thereto. The units project beyond the front and rear walls 4 and 5 and flanges 1 are formed on the walls 4 and 5 about the openings to form seats for the units 6 and said units are secured 45 to the front and rear walls at the openings by solder. The units 6 are arranged horizontally and air is adapted to pass therethrough with the water passing upon the exterior thereof. Also, the water may pass through said units by a series of tubes 8 traversing each unit. The tubes will be contacted by the air passing through the units so that said air may readily absorb heat from the tubes and consequently lower the temperature of the water passing through the tubes. The air also absorbs heat from the walls of the unit so that the water contacting with the exterior walls of the units will be lowered in temperature.

One end of each unit is bent upon itself to form an exterior reinforcing flange 9 which will abut the front wall 4 While the opposite end of the unit is bent upon itself to form an internal reinforcing flange l0. The flanges 9 and l0 thus formed on the unit will permit the unit to be readily removed from the front and rear walls when the solder securing the front and rear walls to said unit is removed. This arrangement permits any one of the units to be readily removed when damaged and replaced by another, consequently materially reducing the cost of repairing the radiator when defective or damaged.

Opposite walls of each unit are crimped or bent inwardly to form spaced internal ribs Il acting as air delectors. The air passing through the units striking the ribs is deflected against the tubes assuring quicker and better cooling of the water passing through the tubes.

Having described the invention, we claim:

A radiator comprising a casing including upper and lower water chambers connected by a water passage having front and rear walls provided with rows of openings with the openings of one row arranged in staggered relation to the openings of the adjacent row, air passage units extending through said openings and secured to the front and rear walls, water tubes traversing each unit so that air passing through the units may contact with the tubes, said units having opposite walls thereof provided with spaced elongated oifsets to form grooves arranged exteriorly of the units and to provide ribs interiorly of said units for deflecting the air passing through` the units against the tubes, flanges formed on the front and rear walls about the openings and forming seats for the units, each unit having one end bent upon itself to form an external ange to abut the front wall and its opposite end bent upon itself to form an internal reinforcing flange.
