Heat sinks that cool electronics are mounted within a subsea housing or vessel. Springs are used to provide pressure between the heat sinks and a vessel wall. Vessel wall deformation caused by external seawater pressure is absorbed by the springs, which maintain a pre-load force according to the spring characteristics. The mechanism also allows for rack mounting of the electronics without the need for manual access in the relatively compact vessel or housing.

Systems according to the present disclosure provide one or more surfaces that function as heat or power radiating surfaces for which at least a portion of the radiating surface includes or is composed of fractal cells placed sufficiently closed close together to one another so that a surface (plasmonic) wave causes near replication of current present in one fractal cell in an adjacent fractal cell. A fractal of such a fractal cell can be of any suitable fractal shape and may have two or more iterations. The fractal cells may lie on a flat or curved sheet or layer and be composed in layers for wide bandwidth or multibandwidth transmission. The area of a surface and its number of fractals determines the gain relative to a single fractal cell. The boundary edges of the surface may be terminated resistively so as to not degrade the cell performance at the edges.
