1 Claim.

This invention relates to an improved heat dissipating device for internal combustion engines of the V or radially disposed bank type.

An object of this invention is to provide a heat dissipating device for use in conjunction with liquid cooled engines and which taps an equal amount of coolant from` each bank of cylinders.

Another object of this invention is to provide a heat dissipating device of the character described which tends to heat each bank of cylinders at an even temperature by draining equal amounts of coolant from each bank thereof.

A further object of this invention is to provide a heat dissipating device adapted to conduct and give off through the medium of convection an optimum amount oi heat per unit area of the device when used in conjunction with a V type or radially disposed bank type engine.

A still further object of this invention is to provide a heat dissipation means for liquid cooled internal combustion engines of the multi-bank type, which has a radiator composedof a plurality of cells, each cell particularly adapted to be used with a single bank of cylinders in an engine.

A still further object of this invention is to provide a device of the character described which is ecient in operation and inexpensive lending Well to commercial manufacture.

With these objects in view and others which will be specifically pointed out or which will become readily apparent to those skilled in the art, reside in description of a single preferred embodiment of this inventive concept taken in conjunction with the appended drawings where- Figure 1 is a perspective view of the invention showing the same applied to a V type engine;

Figure 2 is a side view of the heat dissipating means forming part of the instant invention;

Figure 3 is a back view of the instant invention taken on Figure 2 in the direction of arrow 3;

Figure 4 is a sectional View of the heat dissipating means taken on Figure 2 and on the line i-4 in the direction of the arrows; and,

Figure 5 is a sectional plan View of Figure 2 taken on the line 5 5 thereof and in the direction of the arrows)i Referring now more in detail to the instant invention wherein like reference characters are used to indicate similar parts throughout the views of the invention, the reference numeral Way.

and 26.

A radiator or heat dissipating means housing l 2 composed of the conventional material, usually copper, is provided with the usual vertical tubes I4. The radiator forming |part of the instant invention is conventional in every respect except that it is provided in two sections or cells I6 and I8 having associated outlets 20 and 22 and having associated inlets 24 and 2E. As is apparent from an inspection of Figures 4 and 5 the only alteration necessary to convert a conventional radiator to this improved type used in conjunction with the instant invention, is the addition of the baiiies 28 and 30 and an extra pair of hose connections to the said conventional radiator.

The operation of the instant invention is as follows. Secured by means of suitable hose connections 38 to the engine liquid coolant outlet members 36 are the radiator inlet connectors 24 The- radiator outlet connections 20 and 22 are secured to the engine liquid coolant inlets 34 by suitable connectors such as the hoses 32 shown in Figure l. The advantages of this device in its operation are now quite evident. There has been great diiculty in providing an eiicient heat radiating means of this nature in V type engines since the conventional unit receives its liquid coolant from one bank of cylinders thus receiving not only the hottest portion of the liquid coolant but also the cooler portion. In the instant invention, the hottest water or other liquid coolant is drained from each bank of cylinders and is received in a separate cell for heat dissipation thereof. It is also noted that in a conventional device Water is drained from a single bank of cylinders thus affording more cooling to that particular bank and causes uneven and detrimental wear in the engine. As mentioned herein before only the hotter portion of the water in each bank is drained for use in the especially constructed heat dissipating means and an equal portion of water (or some other coolant) is drained from each individual bank.

While there is illustrated but a preferred ernbodirnent of the instant invention, it will become apparent to those skilled in the art that various changes, including additions and omissions, may be made herein Without departing from the spirit and scope of this invention as set Aforth in the accompanying claim.

Having thus described this invention, what is claimed is: y

In an internal combustion engine, a plurality of banks of cylinders, cylinder heads disposed on said banks, a plurality of liquid cooling systems in association with said banks of cylinders and said heads, outlet hoses extending from said heads to conduct heated fluid therefrom, and inlet hoses for conducting cooled liquid to said banks of cylinders, a multi-cell heat dissipating means operably associated with said engine, each of said cells receiving a selective portion of hottest portion liquid from the single cooling system associated with a single bank of cylinders, means connecting said heat dissipating means and said inlet hoses for conducting liquid from said heat dissipating means to said inlet hoses for recirculation of the liquid in the banks of cylinders and heads of the cooling systems.
