AI Technical Summary
The heat pipes of existing 3D vapor chambers lack vertical support structures, which leads to poor return of the working fluid and can easily cause dry burning in the evaporation zone and heat dissipation failure.
The heat dissipation structure adopts a column and a connecting ring. The connecting ring is integrally formed with the column and is connected to the heat pipe opening at the top, ensuring that the working fluid flows in both horizontal and vertical directions and improving the return flow efficiency.
The vertical structural strength of the heat pipe has been enhanced to ensure smooth return of the working fluid, prevent dry burning in the evaporation zone, and improve heat dissipation efficiency.
