Abstract
Abstract A heating and cooling assembly in association with an internal combustion engine for minimizing the effect of temperature extremes on engine components. The assembly includes an enclosure which is located beneath or near the radiator such that the radiator traverses and divides the enclosure for forming air flow channels into the enclosure. The movement of air through the radiator passes across the channel openings and into the enclosure for creating a slight differential pressure which enhances the flow of air through the enclosure. Valves or baffles are provided such that the assembly may be switched from summer to winter operation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
105 words
An internal combustion engine mounted within a compartment, said engine having a fan assembly, and a radiator mounted within said compartment in proximity with said fan assembly, wherein the improvement comprising: an air flow directing assembly, said air flow assembly including an enclosure located adjacent said radiator, said enclosure having side walls and a bottom wall for supporting an engine component, said enclosure including first and second openings which are formed on opposite sides of said radiator, and said fan assembly directing air flow through said radiator and across said openings such that air flows through said enclosure for heating or cooling said engine component.
Claim 2
Dependent Claim
105 words
An internal combustion engine mounted within a compartment, said engine having a fan assembly, and a radiator mounted within said compartment in proximity with said fan assembly, wherein the improvement comprising: an air flow directing assembly, said air flow assembly including an enclosure located adjacent said radiator, said enclosure having side walls and a bottom wall for supporting an engine component, said enclosure including first and second openings which are formed on opposite sides of said radiator, and said fan assembly directing air flow through said radiator and across said openings such that air flows through said enclosure for heating or cooling said engine component.
Claim 3
Dependent Claim
37 words
In the construction as defined in claim 1 wherein said radiator traverses and divides said enclosure such that air flow is channeled through the enclosure below or near said radiator in a generally U-shaped air flow path.
Claim 4
Dependent Claim
37 words
In the construction as defined in claim 2 wherein said enclosure includes a third opening, and valve means for directing air flow between two of said openings for selectively permitting heating or cooling of said engine component.
