Abstract
A heating apparatus for a fluid flow system having a fluid conduit includes at least one heater element and a support member within the conduit. The at least one heater element includes a resistance wire, a sheath, and an electrically insulating material. The sheath has a closed profile shape that extends along a tortuous path through the container body and surrounds the resistance wire along the tortuous path. The insulating material is disposed about the wire between the wire and the sheath. The support member restricts movement of the at least one heater element relative to the fluid conduit. The support member defines a corrugated geometry that follows the tortuous path while contacting the sheath along a majority of a length of the sheath. The support member increases heat transfer from the at least one heater element to a fluid flowing through the fluid conduit.
