1Temperature
If nanometer-scale heat dissipation holes are created on the housing surface, then heat dissipation efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The housing is designed with a porous structure containing numerous nanometer-scale heat dissipation holes distributed on its surface. This porous configuration dramatically increases the surface area available for heat exchange, enabling efficient thermal dissipation while maintaining the housing's structural integrity and aesthetic appearance.
Solution Approach 2:
The invention transitions from conventional two-dimensional heat dissipation surfaces to a three-dimensional porous structure with nanometer-scale holes penetrating through the housing. This dimensional transformation creates extensive internal surface area for heat exchange, significantly enhancing heat dissipation efficiency without increasing the housing's external dimensions.
2Area of stationary object
If nanometer-scale holes are formed using photolithography and chemical etching, then heat dissipation surface area is increased, but manufacturing precision requirements increase
Solution Approach 1:
The invention replaces conventional mechanical drilling or punching methods with photolithography and chemical etching processes. This substitution enables precise control over hole dimensions and uniform distribution at the nanometer scale, achieving the required manufacturing precision through photochemical reactions rather than mechanical force.
Solution Approach 2:
The manufacturing process utilizes controlled changes in chemical concentration, exposure time, and etching parameters to achieve consistent nanometer-scale hole dimensions. By precisely adjusting these process parameters, the invention achieves uniform hole sizes and optimal density distribution across the housing surface.
