摘要： An electric heater includes a first busbar, a second busbar, a third busbar, a neutral busbar, a plurality of first heating elements, a plurality of second heating elements, and a plurality of third heating element. A first end of each first heating element is coupled to the first busbar for electrical communication therewith. A second end of each first heating element is coupled to the neutral busbar for electrical communication therewith. A first end of each second heating element is coupled to the second busbar for electrical communication therewith. A second end of each second heating element is coupled to the neutral busbar for electrical communication therewith. A first end of each third heating element is coupled to the third busbar for electrical communication therewith. A second end of each third heating element is coupled to the neutral busbar for electrical communication therewith.

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.

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 heater assembly includes a continuous series of perforated helical members and a plurality of electrical resistance heating elements. The perforated helical members cooperate to define a geometric helicoid disposed about a longitudinal axis of the heater assembly. Each perforated helical member defines opposed edges and a predetermined pattern of perforations. The perforations extend through each perforated helical member parallel to the longitudinal axis. The heating elements extend through the perforations.
