Abstract
A fluid swivel which will tend to generate heat by the sliding friction of the seals on the mandrel which has cooling through the central portion which has enhanced cooling by providing a greater heat transfer area in a restricted area than would be available from a common circular drilled hole.
Claims16
A swivel for the rotary connection of a fluid passageway from a non-rotating location to a rotating location, comprising
- an outer body having one or more fluid inlet ports and having one or more cooling fluid ports,
- a mandrel having one or more fluid passages and one or more cooling passages,
- two or more seals sealing between said outer body and said mandrel which generate heat due to the sliding motion between said seal and said mandrel or said seal and said outer body,
- said cooling passage for communicating a cooling medium thru said mandrel,
- said cooling passage having a cross section area and having heat transfer surfaces to communicate said heat from the materials of said mandrel to said cooling fluid,
- said heat transfer surface area being greater than the heat transfer surface area that would be provided by a cylindrical passage of the same cross section area.
In a reel for handling one or more hoses from an offshore floating facility such as a drilling vessel or a service vessel to subsea drilling or service equipment, a swivel with an internal cooling passage having a surface area for transferring seal friction generated heat from said swivel to a cooling medium,
- said surface area being greater than the surface area of a circular hole of the same cross section area.
