## Abstract

An intercooler assembly for cooling charge air to be delivered to an internal combustion engine is disclosed. The said assembly is disposed along an axis in the axial direction, including an intercooler housing having a housing cavity for receiving an intercooler core therein. Conventional cooling fluid is channeled axially through an axial chamber of the intercooler core for cooling the core and charge air is channeled around the outer surface of the core for cooling the charge air, wherein the core assembly further including a means for rotating the intercooler core about the axis, thereby increasing the cooling of the charge air as it flows around the outer surface of the intercooler core.

## Claims

### Claim 1

An intercooler assembly for cooling charge air to be delivered to an internal combustion engine comprising:
a) a core assembly disposed along an axis in the an axial direction;
b) the core assembly including an intercooler housing having a housing cavity for receiving an intercooler core therein;
c) wherein cooling fluid is channeled axially through an axial chamber of the intercooler core for cooling the core and charge air is channeled around the outer surface of the core for cooling the charge air;
d) wherein the core assembly further including a means for rotating the intercooler core about the axis thereby increasing the cooling of the charge air as it flows around the outer surface of the intercooler core.

### Claim 2 (depends on 1)

The intercooler assembly claimed in claim 1 wherein the rotating means including a motor connected to a drive sprocket driving a driven sprocket attached to the intercooler core thereby rotating the core.

### Claim 3 (depends on 1)

The intercooler assembly claimed in claim 1 wherein the rotating means including axial ribs projecting radially from the outer surface of the intercooler core for rotatably urging the intercooler core when air received through an air inlet in the intercooler housing impinges on the radial ribs.

### Claim 4 (depends on 3)

The intercooler assembly claimed in claim 3 wherein the intercooler housing including angled air passageways for directing the charge air at an angle towards the axial ribs.

### Claim 5 (depends on 1)

The intercooler assembly claimed in claim 1 wherein the rotating means including a turbine connected to the intercooler core, the core assembly adapted to direct cooling fluid over the turbine thereby rotating the core when cooling fluid passes over the turbine.

### Claim 6 (depends on 1)

The intercooler assembly claimed in claim 1 wherein the core assembly mounted to the intercooling housing with bearings and including seals to prevent cooling fluid from leaking form the axial chamber.
