What is claimed is: 1. A guide vane for a gas turbine engine, said guide vane comprising: an aerodynamic outer shell; a mechanical load carrying spar disposed within said outer shell and separated therefrom by a gap therebetween; a plurality of stiffeners mounted on said spar; at least a portion of each stiffener including a longitudinal thermal fin for dissipating heat from said outer shell to said gap and said spar; and at least one of said longitudinal thermal fins extending partially into said gap; wherein said stiffeners are generally T-shaped in cross-section, each comprising a base mounted on said structural spar and said longitudinal thermal fin extending outwardly from said base toward said aerodynamic outer shell. 2. The guide vane of claim 1 wherein at least one of said longitudinal thermal fins engages an inner surface of said outer shell. 3. The guide vane of claim 1 wherein said spar is hollow. 4. The guide vane of claim 3 wherein said spar includes at least one stiffening rib connected at opposed edges thereof to generally opposed locations on the interior of said spar. 5. A guide vane for a gas turbine engine, said guide vane comprising: an aerodynamic outer shell; a mechanical load carrying spar disposed within said outer shell and separated therefrom by a gap therebetween; a plurality of stiffeners mounted on said spar; at least a portion of each stiffener including a longitudinal thermal fin for dissipating heat from said outer shell to said gap and said spar; and at least one of said longitudinal thermal fins extending partially into said gap; wherein said spar is solid.
