AI Technical Summary
Traditional plug-in type heat sinks have a small contact area between the heat sink fins and the base, resulting in slow heat conduction and poor heat dissipation.
A heat dissipation base is designed with slots, through which heat sinks are fixed by soldering and connected in groups by latches, increasing the contact area between the heat sinks and the base. Solder paste is used for fixing, thereby improving the connection strength between the heat sinks and the base.
By increasing the contact area between the heat sink and the base, the heat dissipation speed is significantly accelerated, and the heat dissipation effect is improved.
