Concentric Heat Generator Design for High Capacity

The patent implements nesting by placing one cylindrical member inside another cylindrical member, creating concentric passages for fluid flow. The inner member contains an impeller that rotates within the outer member, maximizing the use of internal space. This nested configuration allows the heat generator to achieve large heating capacity without requiring a proportionally large external diameter, as the heating elements and fluid passages are efficiently arranged in concentric layers.

The patent transitions from a two-dimensional disc-like configuration to a three-dimensional cylindrical configuration with concentric passages. By utilizing the radial dimension and creating multiple fluid passages arranged concentrically around a central axis, the design achieves increased heat capacity without proportionally increasing the external footprint. The fluid flows through multiple concentric zones, effectively using vertical and radial space to maximize heating capacity within a compact cylindrical envelope.

The patent divides the heat generator into distinct functional segments: an outer member with an outer passage, an inner member with an inner passage, and an impeller. Each segment has a specific function - the outer member provides structural support and contains the outer fluid passage, the inner member contains the impeller and inner passage, and the impeller provides rotational motion. This segmentation allows for modular manufacturing and assembly, reducing overall device complexity compared to a monolithic design while still achieving large heating capacity through the combined functionality of multiple segments.

The rotating inner member serves multiple functions simultaneously: it acts as a structural component defining the inner passage, houses the impeller for fluid agitation, and functions as a heating element through eddy current induction. The outer member similarly serves as both a structural housing and a container for the outer fluid passage. This multi-functionality reduces the number of separate components needed, thereby reducing device complexity while maintaining large heat capacity.

The patent employs periodic action through the rotating impeller that periodically agitates and moves the fluid through the passages. The rotational motion creates periodic eddy currents in the conducting cylinder, which generates heat through electromagnetic induction. This periodic electromagnetic action ensures continuous heating as the fluid passes through, maintaining heating efficiency even at higher flow rates where the fluid spends less time in the heating zone. The periodic nature of the eddy current generation ensures consistent energy transfer to the fluid.

The patent ensures continuity of useful action by designing concentric passages that allow fluid to flow continuously through multiple heating zones. The outer and inner passages are arranged so that fluid flow through one passage can be followed by flow through the other, creating a continuous heating process. The rotating impeller maintains continuous agitation and heat generation through uninterrupted eddy current induction, ensuring that heating action continues without interruption even as fluid moves rapidly through the system, thereby maintaining efficiency at high flow rates.
