Shared-Sheet Heat Pipe Assembly to Reduce Solar Collector Warping

The patent merges multiple heat pipe reservoirs into a single common reservoir formed by first and second sheets, allowing multiple heat pipes to share the same fluid chamber. This combining approach reduces the number of separate components that need to be manufactured and assembled, thereby lowering production costs while maintaining the functional integrity of each heat pipe through individual hot parts and shared cold parts

The patent segments the heat pipe structure into distinct hot parts and cold parts, with the hot parts remaining separate for individual solar collector integration while the cold parts converge to form a common reservoir. This segmentation allows each heat pipe to maintain its structural identity and thermal performance while benefiting from the cost savings of a shared reservoir structure

The patent merges multiple cold parts into a single integrated cold part structure that forms part of the common reservoir. This merging provides structural rigidity and stability, reducing the warping risk that would occur if each cold part were separately connected to the conduit. The unified cold part structure distributes thermal stresses more evenly while maintaining effective heat exchange with the conduit

The patent employs different materials for the first and second sheets (potentially including metallic materials with appropriate thermal and mechanical properties) to create a composite structure that balances thermal conductivity for heat exchange with mechanical strength to resist warping. The material selection and configuration provide both heat transfer efficiency and structural stability under thermal loading conditions
