Abstract:
A heat exchanger system for dissipating heat generated by components contained within a thermally insulated antenna mounted atop a periscope tube, comprising:a first wall of thermally conductive material having a first face and a second face, said first face shaped to substantially contact an internal portion of said periscope tube;a plurality of ribs made from thermally conductive material fixedly coupled to said second face of said first wall for good heat transfer therebetween;a second wall of thermally conductive material opposing said second face of said first wall and in tangential contact with said plurality of ribs to form a fluid seal therewith, wherein at least one channel is formed between said first wall and said second wall;said plurality of ribs each having two ends, each said end being offset from each end of adjacent ones of said plurality of ribs such that said at least one channel defines a flow path having a first end and a second end;a heat pipe residing partially in said thermally insulated antenna and partially in said periscope tube, wherein said components generating heat are thermally coupled to said heat pipe; anda liquid coolant delivery system coupled to said first end and said second end of said flow path, said liquid coolant delivery system pumping a liquid coolant into said first end and recapturing said liquid coolant exiting said second end, said liquid coolant delivery system passing said liquid coolant exiting said second end over a portion of said heat pipe in said periscope tube, wherein heat transfer between said liquid coolant and an ambient environment is transferred primarily from said plurality of ribs through said first wall and said periscope tube.
