An apparatus (10) for the controlled heating of fluid comprises a general elongated electrically heating core (16) with an exterior surface (36) formed of a material having a high thermal conductivity and frustoconically shaped to slidingly receive an assembly (14) so that the assembly envelops the surface along at least a portion of the length of the core. The assembly (14) forms a sealed passageway (46) for generally unidirectional sheet-like flow upward along the core (16). A control system (20) selectively operates the heating core (16) so that the fluid, under varying flow rates, is warmed to a desired temperature without overheating, before the fluid flows from the passageway (46).

[ What is claimed is:] [6.] An apparatus for warming a flow of fluid comprising:an assembly shaped generally frusto-conical and defining a longitudinal axis, the assembly forming an inlet and outlet and a sealed passageway for the fluid from the inlet to the outlet, the inlet being proximate one end of the assembly and the outlet being proximate the other end of the assembly, the assembly including an exterior restraint defining an outer boundary of the passageway;a general elongated heated mandrel defining a longitudinal axis, the mandrel having an exterior surface with at least a portion formed of a material having a high thermal conductivity and shaped to slidingly receive the assembly so that the assembly envelops the exterior surface along at least a portion of the length of the mandrel, the exterior surface defining an inner boundary of the passageway, the assembly and the exterior surface of the mandrel being configured to form the passageway with a generally constant thickness over at least a portion of the length of the passageway when the assembly is disposed in a desired position relative to the mandrel.
