摘要： A heater includes a flow guide and electrical resistance heating elements. The flow guide defines a continuous geometric helicoid disposed about a longitudinal axis and defines perforations that extend in a longitudinal direction through a first longitudinal length of the geometric helicoid. The first longitudinal length is less than a full longitudinal length of the geometric helicoid. The electrical resistance heating elements extend through the perforations. For each electrical resistance heating element, a length of that electrical resistance heating element and a pitch of the geometric helicoid at a distal end of that electrical resistance heating element are such that the distal end of that electrical resistance heating element is a distance X from the geometric helicoid at the distal end of that electrical resistance heating element. The distance X is less than or equal to 40% of the pitch at the distal end of that electrical resistance heating element.

摘要： A termination assembly for a heater assembly includes a plurality of resistive heaters arranged in discrete power phases, each resistive heater comprising a resistive heating element surrounded by dielectric material and a sheath. The termination assembly includes a plurality of electrically nonconductive members. Each electrically nonconductive member includes a plurality of apertures configured to receive power pins of the plurality of resistive heaters. The termination assembly includes a plurality of connectors configured to connect the power pins to the electrically nonconductive members. Each electrically nonconductive member includes a number of the plurality of connectors corresponding to a number of power pins being terminated. The termination assembly includes an electrical circuit embedded in or disposed on at least one of the plurality of electrically nonconductive members.

摘要： A heater assembly includes a pair of heating sections and a coupling assembly. The heating sections each include a conductive portion. The coupling assembly includes a coupling enclosure and a coupling member disposed inside the coupling enclosure. The conductive portions of the pair of heating sections are connected by the coupling member inside the coupling enclosure.

摘要： A terminal assembly for a heater system includes a plurality of resistive heating elements arranged in multiple power phases includes a plurality of power busbars, a neutral busbar, a phase barrier disposed between each of the plurality of power busbars, and a plurality of interchangeable couplers. Each power busbar corresponds to a power phase of the multiple power phases and is configured to connect a power lead from one of the multiple power phases and a first end of a plurality of resistive heating elements. The resistive heating elements are in electrical communication with the power lead. The neutral busbar is offset longitudinally from the power busbars and configured to receive a second end of the resistive heating elements. The interchangeable couplers are configured to connect at least a subset of the resistive heating elements to at least one power busbar or at least one neutral busbar.

摘要： A heater includes a flow guide and a plurality of electrical resistance heating elements. The flow guide defines a continuous geometric helicoid disposed about a longitudinal axis of the heater assembly. The flow guide defines a predetermined pattern of perforations that extend in a longitudinal direction through a first longitudinal length of the geometric helicoid, the longitudinal direction being parallel to the longitudinal axis. The plurality of electrical resistance heating elements extend through the perforations. At least one electrical resistance heating element of the plurality of electrical resistance heating elements has a first region with a first watt density and a second region with a second watt density. The second region is located farther in the longitudinal direction than the first region. The second watt density is less than the first watt density.

The flow guide defines a continuous geometric helicoid disposed about a longitudinal axis of the heater assembly. The flow guide defines a predetermined pattern of perforations that extend in a longitudinal direction through a first longitudinal length of the geometric helicoid. The longitudinal direction is parallel to the longitudinal axis. The geometric helicoid has a first pitch at a first zone along the longitudinal axis and a second pitch at a second zone along the longitudinal axis. The second pitch is shorter than the first pitch. The electrical resistance heating elements extend through the perforations.
