Abstract

A line of sight blocker including a cover defining a duct bounded by the cover and a heated surface when the cover is fastened over the heated surface. The cover blocks transmission of infrared radiation emitted from the heated surface; the cover comprises a material having a lower thermal conductivity than the heated surface; and the duct comprises a vent and a path for latent heat from the heated surface to escape through the vent.
