Description

June 20, 1933., M. NEWMAN AUTOMOBILE RADIATOR Filed Feb. 14,

Patented June 20, 1933 UNITED STTES MORRIS NEWMAN, OF KINGSTON, NEW YORK AUTOMOBILE RADIATOR Application filed February 14, 1930.

My invention relates to improvements in automobile radiators and the object of the invention is to devise a radiator which will produce greater cooling eiiect upon the water or other cooling medium circulated therethrough, thus enabling a radiator of smaller liquid capacity to be used than is normally the oase. Alternatively, a radiator of standard capacity when constructed according to my invention will give increased cooling eect.

Another object is to construct a radiator in such a manner that it will be readily adaptable to production in quantity with a consel quent saving in cost, and which in addition can be readily repaired should it be damaged.

With these and other object-s in view which will hereinafter appear, my invention consists of an automobile radiator constructed and arranged, all as hereinafter more particularly described and illustrated in the accompanying drawing in which Fig. l represents a front elevation of a radiator constructed according to my invention.

Fig. 2 is a vertical cross section thereof taken on the line 2-2 Fig. l.

Fig. 3 is an enlarged fragmentary horizontal section through the radiator on line 3-3, Fig. 1, and

Fig. 4 is a similar vertical section on line 4-4, Fig. 2.

Fig. 5 is a plan view of a portion of the strips Jforming the cooling medium passage walls.

Fig. 6 is a similar View of a portion of a combined spacer and radiation strip adapted to be inserted between the exterior faces of adjacent cooling medium passage wall strips, and

Fig. 7 is a side view of the strip illustrated in Fig. 6.

Like characters of reference indicate corresponding parts in the diierent views.

The usual radiator shell 1 extends around Serial No. 428,350.

the radiator proper' and the upper and

lower headers

2 and 3 respectively communicating therewith.

In the present embodiment of the invention the radiator proper comprises a plurality ofL vertical strips 4 with the portions of their faces in the vicinity of their side edges oi set so that they abuteach other and are secured together by any suitable means such as soldering, thus leaving a space between the c strips of each pair which constitutes a water passage extending from the upper header 2 to the lower header 3. rllhe strips 4 have preferably transversely disposed arrowshaped corrugations 6 therein to increase the cooling area, to cause the water in circulating down through the passage 5 to follow a tortuous path and also to add rigidity to the structure.

In forming the radiator instead of each 1 rial forming the strips 4 to close the air spaces g 7 to the

headers

2 and 3 while permittingof communication being established between the water passages 5 and such headers.

A spacer and radiation strip 8 is introduced into each air space 7 formed by the cellular section, and such strips have front and back portions bent angularly to constitute deiiecting baiiies 9 to cause the air drawn through the air spaces 7 to follow a zigzag; course, thus producing the. maximum cooling effect on the strips 4 constituting the side walls of the water passages 5. The construction of such strips 8 is clearly illustrated in Figs. 6 and 7. To increase the rigidity and maintain the proper positioning Q0 of the spacer strips 8 they may be provided with a plurality of corrugations 10.

In constructing the radiator proper the respective sections are formed up and assembled side by side. The edges are then laid in solder with the result that the offset faces of abutting strip portions 4 are sealed together. The

headers

2 and 3 are then soldered on in the usual manner.

In appearance a radiator constructed according to my invention approximates aL honeycomb radiator but is not liable to be- Colney choked up with deposits from the cooling medium, it can be manufactured eX- ceedingly economically and is susceptible to easy repair.

Vhat I claim is my invention is:

l. In an automobile radiator the combination with the adjacent walls of spaced adjacent water passages, of a combined spacer and radiation strip inserted into the space between each adjacent pair of water passages and comprising a strip having its vertical marginal edges laterally slit to constitute a plurality of baflies twisted into a horizontal position and abutting the inner faces of the vertical walls of the cell.

2. In an automobile radiator the combination with the adjacent walls of spaced adjacent water passages, of a combined spacer and radiator strip inserted into the space between each adjacent pair of water passages and comprising a strip the body portion of which is corrugated and the vertical marginal edges laterally slit to constitute a plurality of baliies twisted into a horizontal position and abutting the inner faces of the vertical walls of the cell.

3. In an automobile radiator in combination, an upper and lower header, a plurality of strip members, each of which is bent into elongatedy box-like form to constitute an integral cell, the body portions of the vertical walls of adjacent cells being corrugated and the vertical side edge portions being plane surfaces offset from the corrugated body portionsand secured together whereby water passages are constituted communicating with the upper and lower headers, including a vertical combined spacer and radiation strip inserted into each cell and comprising a strip having its vertical marginal edges laterally slit to constitute a plurality of bales twisted into a horizontal position and abutting the inner faces of the vertical walls of the cell.

4. In an automobile radiator in combination, an upper and lower header, a plurality of strip members, each of which is bent into elongated box-like form to constitute an integral cell, the body portions of the vertical walls of adjacent cells being corrugated and the vertical side edge portions being plane surfaces offset from the corrugated body portions and secured together whereby Water
