Breathable radome
A “breathable” radome that has an air-permeable structure is disclosed. The air-permeable structure permits a relatively greater flow of cooling air to be drawn over the radiating elements of an air-cooling system that is used for the electronics that are being sheltered by the radome. The increase in cooling efficiency that results from the use of the breathable radome enables air-cooled systems to be used with relatively higher-powered electronics.
1. An apparatus comprising a radome for use with electronics equipment, wherein said radome comprises a shell that defines an internal environment and provides a barrier between said electronics equipment in said internal environment and an ambient environment, and wherein said shell comprises:
(a) a core, wherein said core has an open structure suitable for passing a flow of air; and
(b) a first layer of a composite material proximal to said internal environment and a second layer of said composite material proximal to said ambient environment, wherein said first layer and said second layer sandwich said core, and wherein said first layer and said second layer are physically adapted to pass a flow of air,
wherein the ability of said core, said first layer, and said second layer to pass a flow of air enables air-flow between said ambient environment and said internal environment.
2. The apparatus of claim 1 wherein said open structure of said core is cellular.
3. The apparatus of claim 2 wherein the geometry of said cellular and open-structure core is honeycomb.
4. The apparatus of claim 1 wherein said first layer and said second layer comprise perforations that permit the flow of air there through.
5. The apparatus of claim 1 wherein said shell further comprises a breathable fabric that covers said second layer of composite material.
6. The apparatus of claim 5 wherein said fabric is waterproof.
7. The apparatus of claim 1 wherein said apparatus is a air-cooling system, and wherein said air-cooling system further comprises heat-radiating elements, wherein said heat-radiating elements are disposed in said internal environment and are thermally coupled to said electronics equipment.
8. The apparatus of claim 7 further comprising a fan, wherein said fan generates said air-flow and draws said air flow over said heat-radiating elements.
9. The apparatus of claim 7 wherein said electronics equipment comprises electronics for use in conjunction with an antenna.
10. The apparatus of claim 7 wherein said electronics equipment comprises electronics for use in conjunction with radar.
11. The apparatus of claim 1 wherein said electronics equipment comprises electronics for use in conjunction with an antenna.
12. The apparatus of claim 1 wherein said electronics equipment comprises electronics for use in conjunction with radar.
13. An apparatus comprising a radome for use with electronics equipment, wherein said radome comprises:
a shell that defines an internal environment and provides a barrier between said electronics equipment in said internal environment and an ambient environment, and wherein said shell comprises:
(a) a core, wherein said core has an open structure suitable for passing a flow of air; and
(b) a first layer of a composite material proximal to said internal environment and a second layer of said composite material proximal to said ambient environment, wherein said first layer and said second layer sandwich said core, and wherein said first layer and said second layer are physically adapted to pass a flow of air;
and wherein the apparatus further comprises heat-radiating elements, wherein said heat-radiating elements are disposed in said internal environment and are thermally coupled to said electronics equipment for the purpose of removing heat from said electronics equipment.
14. The apparatus of claim 13 further comprising a fan, wherein said fan generates said flow of air and draws said flow of air over said heat-radiating elements.
15. An apparatus comprising a radome for use with electronics equipment, wherein said radome comprises:
a shell that defines an internal environment and provides a barrier between said electronics equipment in said internal environment and an ambient environment, and wherein:
(a) said shell is load sharing; and
(b) said shell is physically adapted to enable air to flow between said ambient environment and said internal environment;
and wherein the apparatus further comprises:
heat-radiating elements, wherein said heat-radiating elements are disposed in said internal environment and are thermally coupled to said electronics equipment for the purpose of removing heat from said electronics equipment; and
a fan, wherein said fan generates said flow of air and draws said flow of air over said heat-radiating elements through said shell to the ambient environment.
