Plate Heater Layout for Uniform End-Region Heat Shrinking

The patent applies local quality by varying the density of heating tubes across different regions of the heater. Specifically, the end regions have a higher density of heating tubes compared to the middle region, creating non-uniform heating tube distribution that compensates for heat loss at the ends. This localized adjustment of heating tube density achieves uniform temperature distribution without requiring a completely complex redesign of the entire heating system.

The patent implements local quality by extending the heating wire length specifically in the end region heating tubes compared to the middle region. This localized increase in heating wire length allows the end regions to generate sufficient heat to compensate for greater heat loss, achieving uniform temperature distribution. The manufacturing complexity is managed by only modifying the heating wire length in specific regions rather than redesigning the entire heating structure.

The patent applies the blessing in disguise principle by converting the harmful heat loss through openings at the ends of the heater into a beneficial design feature. Instead of simply trying to eliminate the openings, the patent uses adiabatic sponges to line the interior walls of the housing, which reflect and retain heat that would otherwise be lost. This transforms the problem of heat loss into an opportunity to implement an energy-efficient heating system with improved uniformity.

The patent applies segmentation by dividing the heating system into multiple discrete heating tubes arranged in a sequence along the longitudinal direction of the housing. Each heating tube can be independently positioned and adjusted, allowing the heating region to be extended to cover all cable clamps. This segmented approach to heating tube arrangement makes it easier to achieve precise positioning and ensures uniform heating across the entire width of the heat shrink tube without requiring extremely high manufacturing precision for the entire system.
