Abstract
Power equipment, e.g. in the form of an electrical sub-station, for use underwater incorporates heat exchange equipment for dissipation of heat to the surrounding water. The equipment may utilise a casing having a hollow tubular element (50) extending therethrough or may utilise an arrangement with two chambers (111, 112) between which a fluid is circulated.
Claims23
Power equipment for use when submerged in water, the power equipment comprising an exterior casing enclosing at least one power device of a type which produces heat when in use, the exterior casing being in heat exchange relationship with the at least one power device so as to put the at least one power device into heat exchange relationship with water surrounding the exterior casing when the power equipment is submerged, the power equipment further comprising a passage penetrating the exterior casing and extending at least partially through the power equipment in heat exchange relationship with the at least one power device, which passage is open to ingress of the water surrounding the exterior casing so as to put the at least one power device into heat exchange relationship with water in the passage when the power equipment is submerged.
Power equipment for use underwater, the power equipment comprising a pressure vessel having
- a first chamber in which is mounted at least one power device which produces heat in use and
- a second chamber at least partially filled with a fluid, the second chamber being in heat conductive relationship with the power device and also having a wall in contact with the water surrounding the power equipment, whereby heat produced by the power device is transmitted to the second chamber and thence transmitted to the surrounding water.
