Exhaust Gas Heating Conductor With Throughflow Openings

The heating conductor is designed with throughflow openings that create a porous-like structure, allowing exhaust gas to flow through the conductor itself rather than around it. This increases the effective heat transfer surface area while maintaining low counter pressure, as the gas passes through the openings rather than being blocked by a solid barrier.

The heating conductor transitions from a two-dimensional surface structure to a three-dimensional volume-utilizing structure by incorporating throughflow openings. This allows the conductor to occupy space in a way that maximizes heat transfer surface area while permitting gas flow through its volume, effectively using the third dimension to resolve the contradiction between surface area and flow restriction.

The heating conductor features a meandering or serpentine geometry with curved sections instead of simple linear paths. This curved configuration increases the heat transfer surface area within the same spatial envelope while still being manufacturable using standard forming processes for metal flat materials, balancing manufacturing simplicity with enhanced heat transfer capability.

The meandering structure of the heating conductor allows it to fold back on itself multiple times, effectively nesting the conductor path within a compact volume. This nested-like configuration maximizes the heat transfer surface area by having the conductor traverse the available space multiple times in a space-efficient manner, while maintaining a relatively simple single-piece construction.
