Abstract
A flexible conduit assembly that includes a central fluid transfer conduit and at least two thermal fluid transfer conduits in overlying relationship to the central fluid transfer conduit at an orientation other than linear relative to the center axis of the central fluid transfer conduit. The flexible conduit assembly may also include an outer jacket concentrically disposed relative to the central fluid transfer conduit with the fluid transfer conduit interposed between the central fluid conveying conduit and the outer jacket.
Claims13
A hose assembly comprising:
- a unitary flexible process fluid conveying conduit having an inner process fluid contacting surface defining a hollow conduit and an opposed outer surface;
- and
- a thermal fluid transfer tubing assembly spirally wrapped around the opposed outer surface of the unitary process fluid conveying conduit, the thermal fluid transfer tubing assembly in thermal communication with the unitary process fluid conveying conduit, wherein the thermal transfer tubing assembly is composed of a plurality of individual thermal transfer fluid tubes, wherein each individual thermal transfer tube comprises an inner surface and an outer surface and wherein a portion of the outer surface each individual thermal transfer fluid tube is in movable abutting contact with the outer surface of at least one other individual thermal transfer fluid tube adjacent thereto, wherein an additional portion of the outer surface each individual thermal process tube contacts the opposed outer surface of the unitary flexible process fluid convey conduit, and wherein the individual thermal transfer fluid tubes move relative to the unitary flexible process fluid conveying conduit as the unitary flexible process fluid conveying conduit bends;
- wherein the unitary flexible process fluid conveying conduit is centrally disposed relative to the thermal transfer tubing assembly.

A flexible hose assembly comprising:
- a unitary flexible polymeric process fluid conveying conduit having an inner process fluid contacting surface defining a single hollow conduit and an opposed outer surface;
- a thermal fluid transfer tubing assembly spirally wrapped around the opposed outer surface of the unitary process fluid conveying conduit, the thermal fluid transfer tubing assembly exterior to and in thermal communication with the unitary process fluid conveying conduit, wherein the thermal transfer tubing assembly is composed of a plurality of individual thermally conductive polymeric thermal transfer fluid conduits, wherein the plurality of individual thermal transfer fluid conduits are each in longitudinal abutting relationship with two other thermal transfer tubes when the thermal transfer tubing assembly is in the spiral wrapped position, and wherein each of the abutting tubes are moveable relative to the unitary flexible polymeric process fluid conveying conduit as the unitary process fluid conveying conduit is bent;
- at least one jacket member concentrically disposed around the spirally wrapped thermal transfer tubing assembly;
- and
- at least one insulation layer interposed between the jacket member and the spirally wrapped thermal fluid transfer tubing assembly.
