Abstract

A cooling system for use in association with an engine encased within an engine compartment, having a remotely positioned cooling fan and radiator. The cooling system includes a containment member operably positioned within the engine compartment. The containment member includes an exposure opening which defines a cavity. The cooling system likewise includes a conduit associated with the containment member. The conduit includes a first end placed in fluid communication with the cavity and a second end extending outside of the engine compartment which is placed in fluid communication with the cooling fan. Circulation of the fan directs the passage of fluid from within the cavity and the conduit.

Claims

1. A cooling system for use in association with an engine encased within an engine compartment, having a remotely positioned cooling fan and radiator comprising:

at least one containment member operably positioned within the engine compartment, the at least one containment member having an exposure opening which defines a cavity; and

at least one conduit associated with each of the at least one containment member, the at least one conduit having a first end placed in fluid communication with the cavity and a second end extending outside of an engine compartment, and placed in fluid communication with the cooling fan, wherein circulation of the fan directs the passage of fluid from within the cavity and the conduit,

wherein the cooling fan rotates such that fluid is passed from within the cavity through the conduit and ultimately beyond the cooling fan.

2. The cooling system of claim 1 wherein the conduit is positioned substantially in parallel with the radiator, to, in turn, preclude the passage of air from within the conduit through the radiator.

3. The cooling system of claim 1 wherein the at least one containment member comprises a plurality of containment members.

4. The cooling system of claim 1 wherein the at least one containment member includes an inlet to facilitate the ingress of air into the cavity.

5. The cooling system of claim 1 wherein at least a portion of the cavity of the at least one containment member includes a sound absorbing material.

6. A method for cooling an engine within an engine compartment comprising:

providing at least one containment member;

positioning the at least one containment member so as to place the exposure opening proximate a source of radiant heat;

providing a conduit;

associating a first end of the conduit with the at least one containment member;

extending a second end of the conduit from within the engine compartment;

associating the second end of the conduit with a circulating fan, wherein the fan draws air from the second end of the conduit; and

drawing air sequentially through the at least one containment member and subsequently through the conduit, toward ultimate drawing beyond the circulating fan.

7. The method of claim 6 further comprising the step of:

reducing the propagation of noise from within the engine compartment.

8. The method of claim 7 wherein the step of reducing the propagation of noise comprises the step of:

positioning sound absorbing material within the cavity of the at least one containment member.

9. A cooling system for use in association with an engine encased within an engine compartment, having a remotely positioned cooling fan and radiator comprising:

a plurality of containment members, each containment member having an exposure opening which defines a cavity;

wherein the cavity is positioned to overlie a source of radiant heat within the engine compartment; and

at least one conduit associated with each containment member, the at least one conduit having a first end placed in fluid communication with the cavity and a second end extending outside of an engine compartment, and placed in fluid communication with the cooling fan, wherein each containment member and associated conduit are structurally configured such that circulation of the fan draws air from proximate each source of radiant heat which is associated with each containment member, through the cavity of each containment member, through the at least one conduit associated with each containment member, ultimately beyond the cooling fan.

10. The cooling system of claim 9 wherein at least one of the containment members further includes a lining positioned within the cavity, to, in turn, absorb noise.

11. The cooling system of claim 9 wherein at least one of the containment members is structurally configured to correspond in shape to a source of radiant heat within the engine compartment.
