A first conduit extends from the housing to direct infrared energy generated by the infrared energy source to a windshield of a vehicle. A second conduit extends from the housing to direct the infrared energy to a passenger cabin of the vehicle. ## Claims ### Claim 1 A vehicle infrared heating assembly comprising: an infrared energy source within a housing; a first conduit extending from the housing to direct infrared energy generated by the infrared energy source to a windshield of a vehicle; and a second conduit extending from the housing to direct the infrared energy to a passenger cabin of the vehicle. ### Claim 2 (depends on 1) The vehicle infrared heating assembly of claim 1, wherein the infrared energy source is an infrared light. ### Claim 3 (depends on 1) The vehicle infrared heating assembly of claim 1, wherein the housing includes a reflective inner surface operable to at least partially reflect the infrared energy. ### Claim 4 (depends on 1) The vehicle infrared heating assembly of claim 1, wherein the first conduit is a fiber optic cable. ### Claim 5 (depends on 1) The vehicle infrared heating assembly of claim 1, further comprising a first door rotatable between a first position in which the first door permits passage of infrared energy through the first conduit, and a second position in which the first door restricts passage of infrared energy through the first conduit. ### Claim 6 (depends on 5) The vehicle infrared heating assembly of claim 5, further comprising a second door rotatable between a first position in which the second door permits passage of infrared energy through the second conduit, and a second position in which the second door restricts passage of infrared energy through the second conduit. ### Claim 7 (depends on 1) The vehicle infrared heating assembly of claim 1, further comprising a third conduit extending from the housing to direct the infrared energy to the passenger cabin of the vehicle; wherein the second conduit is configured to extend towards an upper portion of the passenger cabin, and the third conduit is configured to extend towards a lower portion of the passenger cabin. ### Claim 8 (depends on 1) The vehicle infrared heating assembly of claim 1, wherein the vehicle infrared heating assembly includes only a single infrared energy source. ### Claim 9 (depends on 1) The vehicle infrared heating assembly of claim 1, wherein the infrared energy source is a first infrared energy source, the assembly further comprising: a second infrared energy source within the housing; a divider within the housing separating the housing into a first portion including the first infrared energy source and a second portion including the second infrared energy source, the divider at least substantially restricts passage of infrared energy therethrough, the first conduit and the second conduit extend from the first portion of the housing to conduct infrared energy generated by the first infrared energy source; a third conduit extending from the second portion of the housing to direct infrared energy generated by the second infrared energy source to the windshield of the vehicle; and a fourth conduit extending from the second portion of the housing to direct infrared energy generated by the second infrared energy source to the passenger cabin of the vehicle. ### Claim 10 A vehicle infrared heating assembly comprising: an infrared energy source within an inner housing; an outer housing spaced apart from the inner housing to define a conduit therebetween: an inlet port in communication with the conduit for conveying fluid into the conduit to be heated by infrared energy generated by the infrared energy source; and an outlet port in communication with the conduit to convey fluid out from within the conduit. ### Claim 11 (depends on 10) The vehicle infrared heating assembly of claim 10, wherein the inner housing provides the conduit with a spiral shape. ### Claim 12 (depends on 10) The vehicle infrared heating assembly of claim 10, further comprising a plurality of spaced apart fins extending from the inner housing to the outer housing. ### Claim 13 (depends on 10) The vehicle infrared heating assembly of claim 10, wherein the inlet port and the outlet port are configured to convey at least one of the following through the conduit: engine coolant, wiper fluid, fuel, engine oil, brake fluid, transmission fluid, battery coolant, or power steering fluid. ### Claim 14 A vehicle infrared heating assembly comprising: an infrared energy source within a first housing; a second housing mounted relative to the first housing; and a first conduit defined by the second housing; wherein infrared energy generated by the infrared energy source heats fluid in the first conduit. ### Claim 15 (depends on 14) The vehicle infrared heating assembly of claim 14, further comprising a second conduit extending from the first housing to direct infrared energy generated by the infrared energy source to a target area. ### Claim 16 (depends on 15) The vehicle infrared heating assembly of claim 15, further comprising a third conduit extending from the first housing to direct infrared energy generated by the infrared energy source to a vehicle passenger cabin. ### Claim 17 (depends on 14) The vehicle infrared heating assembly of claim 14, wherein the fluid is at least one of engine coolant, wiper fluid, transmission fluid, battery coolant, fuel, engine oil, brake fluid, or power steering fluid. ### Claim 18 (depends on 14) The vehicle infrared heating assembly of claim 14, wherein the second housing is mounted to an exterior of the first housing. ### Claim 19 (depends on 14) The vehicle infrared heating assembly of claim 14, wherein the second housing is mounted to an interior of the first housing. ### Claim 20 (depends on 14) The vehicle infrared heating assembly of claim 14, wherein the first housing includes a parabolic reflector for the infrared energy source.
