In recent years, Hoi Po was devoted to perform researches in improving heat dissipation efficiency of heatsinks and finally achieved a patented design at the end of 2008. (China Patent No. 200720056708.4)

The patent would be mainly on the subject of increasing the surface areas of the fins of the heatsinks in a homogeneous product design. The fins are hence modified using specially designated machines into different orientated shapes and of different angles in 3-dimensional matrix, including trapezoidal, triangular, rectangular or even wavy fins. The fins could be machined in different surfaces of the base as devised, while various bundles could be fabricated throughout the heatsink base length for further liquid or fluid cooling.
