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.
Claims20
A line of sight blocker, comprising:
- a cover defining a duct bounded by the cover and a heated surface when the cover is fastened over the heated surface, wherein:
- 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 heat from the heated surface to escape through the vent.
2 more elements
An apparatus, comprising:
- a device including a heated surface emitting infrared radiation when the device is in operation;
- a cover disposed over the heated surface;
- and
- a gap between the cover and the heated surface, wherein the gap comprises a path for latent heat from the heated surface to escape from between the cover and the heated surface.
1 more element
An apparatus comprising:
- a shroud that removably and retrofittably couples to a mast, wherein the shroud is sized and shaped to draw air in a gap between the shroud and the mast, and
- the gap forms an insulation layer and provides a path for latent heat from the mast to escape.
