Solution Approach 1:

The patent transforms the traditional single-dimension vertical channel structure into a multi-dimensional alternating pattern with radial delimiting walls that extend in multiple directions. This creates a checkerboard arrangement where channels are defined by alternating first and second delimiting walls, effectively utilizing spatial dimensions to enhance convective exchange without increasing overall panel height or material consumption.

Solution Approach 2:

The convector panel is segmented into multiple functional zones using alternating first and second delimiting walls that radially extend from the central axis. This segmentation creates numerous small convective channels arranged in a checkerboard pattern, increasing the surface area for heat exchange while maintaining compact dimensions and reducing material usage compared to traditional single-channel designs.

Solution Approach 1:

The patent compensates for reduced material thickness by enhancing the three-dimensional convective structure with alternating radial delimiting walls. This multi-dimensional approach increases the effective heat exchange surface area and promotes turbulent flow, thereby improving overall thermal performance despite using thinner sheet metal with lower intrinsic heat conduction.

Solution Approach 2:

The invention changes the geometric parameters of the convective channels by introducing alternating first and second delimiting walls with specific radial extensions. This parameter optimization creates a checkerboard arrangement that enhances convective efficiency and turbulence, allowing thinner material to achieve comparable or superior thermal performance through improved flow dynamics rather than relying solely on material thickness.
