Abstract
According to one embodiment, a heat dissipation system includes an elongated radar absorbing member configured with a thermal dissipation mechanism. The radar absorbing member extends proximate a junction of a microwave antenna enclosure that houses an antenna and a radome that covers an opening in the microwave antenna enclosure. The radar absorbing member absorbs electro-magnetic energy incident upon the junction. The thermal dissipation mechanism absorbs heat generated by the absorbed electro-magnetic energy.
Claims23
A microwave transmission system comprising:
- a microwave antenna enclosure;
- a radome that covers an opening in the microwave antenna enclosure, the microwave antenna enclosure and the radome made of differing materials such that an electrical discontinuity is formed at a junction of the microwave antenna enclosure and the radome;
- an elongated radar absorbing member extending proximate the junction, the radar absorbing member operable to absorb electro-magnetic energy incident upon the junction;
- and
- one or more hollow tubes operable to convey a coolant through the elongated radar absorbing member, the one or more hollow tubes fluidly coupled to a cooling system of a microwave antenna configured in the microwave antenna enclosure having one or more radiating elements, the cooling system operable to remove heat from the radiating elements and the radar absorbing member.
A heat dissipation system comprising:
- an elongated radar absorbing member extending proximate a junction of a microwave antenna enclosure and a radome that covers an opening in the microwave antenna enclosure, the microwave antenna enclosure and the radome made of differing materials such that an electrical discontinuity is formed at the junction, the radar absorbing member operable to absorb electro-magnetic energy incident upon the junction;
- and
- a thermal dissipation mechanism configured in the elongated radar absorbing member and operable to remove heat away from the elongated radar absorbing member, wherein the thermal dissipation mechanism comprises one or more hollow tubes that are operable to convey a coolant through the elongated radar absorbing member for removing heat from the elongated radar absorbing member.
