Solution Approach 1:

The patent employs a vapor chamber containing a working fluid that undergoes phase transitions (liquid to vapor and back to liquid) to transfer heat from the processor. The heating surface causes the working fluid to evaporate, and the vapor condenses on the cooling surface, creating a highly efficient heat transfer mechanism that achieves superior cooling performance while maintaining a relatively simple device structure compared to traditional liquid cooling systems.

Solution Approach 1:

The vapor chamber leverages the latent heat of vaporization and condensation of the working fluid to efficiently manage the increasing heat output from high-performance processors. As the processor generates more heat, the working fluid continuously evaporates at the heating surface and condenses at the cooling surface, providing scalable heat dissipation capacity that matches the increasing thermal load without requiring proportionally larger or more complex cooling systems.
