MEANS FOR COOLING HEATED SURFACES.
Application filed March 21, 1923.
. 'Ihis inventionrelates to the art of cooling heated surfaces and particularly the cylinders of internal combustion engines.
Theobject of the invention is to efliciently cool and maintain at effective thermal efficiency, the cylinders of an engine by the use of air under such conditions as to conserve the expenditure of energy while obtaining the requisite velocity of air flow and the necessary air pressure.
\Vith the above and other objects in View, the invention consists in the novel construction, combination and arrangement herein described, shown, and claimed.
In the accompanying drawings:
Fig. 1 is a front elevation of one form of my invention showing the air jacket in section. r
Fig.- 2 is a side elevation of the arrangement shown in Fig. '1.
Fig. 3 is a side elevation of a modification showing the air jacket in section.
eferring to the drawings, 1 designates an engine having cylinders 2 provided with air cooling flanges or fins 3 which extend circuinferentially around the cylinders and transversely of the air flow as will appear.
These fins 3 are of graded sizes asshown so that large air eddies will be set up as shown by arrow a between the large fins, and also smaller eddies b will be set up between each of the adjacent fins. The greatest cooling effect will be obtained by using fins of this character which are positioned at right angles to the cooling air flow.
As shown in Figures 1 and 2 the engine cylinder is surrounded by the air jacket 4, which is outwardly flared at 5 at the upper end. The lower end of the air jacket is also outwardly flared as at 6 in such a manner as to provide a constantly and gradually increasing cross sectional area topermit the Serial N 0. 626,548.
gradual expansion of the heated air before its discharge to the outside air. A fan 7 is provided at the upper end to cause a downward blast of air. It will be seen that the arrangement described imparts to the air passageway a changing cross sectional area analogous to that in a Venturi tube efficiently inducing the necessary air flow velocity and pressure by utilizing the expansion of the heated gas to help induce this air flow.
In Figure 3 invention is shown as applied to a four cylinder engine, the air jacket 8 being outwardly flared at its upper end as at 9 in order to cause a high velocity of the air flow past the heated cylinders. The heated air is drawn out of the lower end of the air-jacket by suction fans 10, 11 and 12 of graduated sizes, operating in a fan casing 13, which communicates with the outlet flared portion 14 of the air jacket.
The fans 10, 11 and 12 and the corresponding parts of the casing 13 are of progressively constricted diameters to correspond to the altering air flow velocity, and the discharge end portion 14 is so shaped as to efiicientiy utilize the energy expended in approaching atmospheric conditions to help induce the air I claim- Cooling means for the cylinders of an internal combustion engine including a plurality of cooling flanges on the cylinders interposed with each other said flanges having uniformly increasing and decreasing diameters and an air confining acket surrounding the cylinders and spaced therefrom, and having entrance and exit passages located to cause a turbulent air current past the cylinders by contact with the flanges of different sizes at right angles thereto.
In testimony whereof I affix my signature.
