A vehicle cooling system includes a fan, a radiator, a charge air cooler upstream of the radiator, an air conduit supplying air to the charge air cooler, and a cooler for cooling the charge air cooler or air flowing through the air conduit. The cooler includes a housing surrounding a portion of the air conduit, an injector for injecting water into a space between the cooler housing and the air conduit, an outlet pipe for conducting vaporized water out of the space, and a pump for pumping water from a source to the injector. The cooler also includes heat conducting vanes which extend into the space and into an interior of the air conduit.

1. A vehicle cooling system, comprising: a fan;a radiator upstream of the fan;a charge air cooler upstream of the radiator;an air conduit connected to an air inlet of the charge air cooler; anda cooler for cooling the charge air cooler or air flowing through the air conduit, wherein:the cooler comprises:a hollow inner sleeve inserted between an upstream portion of the air conduit and a downstream portion of the air conduit;a hollow outer sleeve which surrounds the inner sleeve and which forms an annular space therebetween;a plurality of heat conducting vanes which extend into the annular space and into an interior of the inner sleeve, the vanes conducting heat away from charge air which flows through the inner sleeve;at least one nozzle for injecting water into the annular space; andan outlet pipe connected to the outer sleeve, so that water vaporized in the annular space can flow through and out of the annular space via the outlet pipe. 2. The cooling system of claim 1, wherein: water and vaporized water flows over an outer surface of the air conduit in a first axial direction; andcharge air flows through an interior of the air conduit in a second direction which opposite to said first direction. 3. The cooling system of claim 1, wherein: a hollow ring-shaped conduit surrounds a portion of the outer sleeve;a supply line connects the ring-shaped conduit with an outlet of a pump; anda plurality of spaced apart injector tubes are in communication with the ring-shaped conduit, each injector tube extending radially inwardly through the outer sleeve and forming a nozzle through which water from the ring-shaped conduit is injected into the annular space. 4. A vehicle cooling system, comprising: a fan;a radiator upstream of the fan;a charge air cooler upstream of the radiator;an air conduit connected to an air inlet of the charge air cooler; anda cooler for cooling the charge air cooler or air flowing through the air conduit, wherein:the cooler comprises a spray conduit positioned adjacent to a portion of an upstream side of the charge air cooler, the spray conduit having a plurality of spray nozzles being outside of the air conduit; anda pump for pumping water from a source to the spray conduit so that water sprays out of the spray nozzles and onto said upstream side and outside of the charge air cooler. 5. The cooling system of claim 4, wherein: the spray conduit comprises a first branch line, a second branch line and a third branch line, the first and second branch lines being connected together to form a loop and the third branch line bisecting said loop. 6. A vehicle cooling system, comprising: a fan;a radiator upstream of the fan;a charge air cooler upstream of the radiator;an air conduit connected to an air inlet of the charge air cooler; anda cooler for cooling the charge air cooler or air flowing through the air conduit, wherein:the cooler comprises a spray conduit forming a loop positioned adjacent to a portion of an upstream side of the charge air cooler, the spray conduit having a plurality of spray nozzles; anda pump for pumping water from a source to the spray conduit so that water sprays out of the spray nozzles and onto said upstream side of the charge air cooler. 7. The cooling system of claim 6, wherein: the spray nozzles are positioned on an interior surface of the loop. 8. A vehicle cooling system, comprising: a fan;a radiator upstream of the fan;a charge air cooler upstream of the radiator;an air conduit connected to an air inlet of the charge air cooler; anda cooler comprising:a cooler housing surrounding a portion of the air conduit;an injector for injecting water into a space between the cooler housing and the air conduit;an outlet pipe for conducting vaporized water out of said space; anda pump for pumping water from a source to the injector;a hollow inner sleeve inserted between an upstream portion of the air conduit and a downstream portion of the air conduit;a hollow outer sleeve which surrounds the inner sleeve and which forms an annular space therebetween; anda plurality of heat conducting vanes which extend into the annular space and into an interior of the inner sleeve, the vanes conducting heat away from charge air which flows through the inner sleeve, the injector comprises at least one nozzle for injecting water into the annular space, and the outlet pipe being connected to the outer sleeve, so that water vaporized in the annular space can flow out of the annular space via the outlet pipe. 9. The cooling system of claim 8, wherein: water and vaporized water flows over an outer surface of the air conduit in a first axial direction; andcharge air flows through an interior of the air conduit in a second direction which opposite to said first direction. 10. The cooling system of claim 8, wherein: a hollow ring-shaped conduit surrounds a portion of the outer sleeve;a supply line connects the ring-shaped conduit with an outlet of a pump; anda plurality of spaced apart injector tubes are in communication with the ring-shaped conduit, each injector tube extending radially inwardly through the outer sleeve and forming a nozzle through which water from the ring-shaped conduit is injected into the annular space.
