AI Technical Summary
Common thermal pads are prone to bending during use and have limited heat dissipation effect, failing to effectively improve heat dissipation efficiency.
Multiple heat-conducting rods are movably inserted into the grooves on the heat-conducting pad, and connecting rods are fixedly installed on the top of the heat-conducting rods. The heat is then connected to the heat sink plate and nuts, and the heat is conducted to the heat sink plate through the heat-conducting rods and connecting rods, thereby increasing the heat dissipation area.
It effectively prevents the gasket from bending and quickly conducts heat to the heat sink through the heat-conducting rod and connecting rod, thus improving the heat dissipation effect.
