One piece pin array heat sinks made from 99.6% pure aluminium

 

 
 

Pinbloc heatsinks are pressed from a single aluminium block to take the form of an array of pins on a base. This is not extrusion!

The pure aluminium has a high thermal conductivity of 220 W/mK. The design is very effective in natural convective cooling, as well as in the forced-air configuration.

 Independent tests have measured thermal performance 30% better than extruded heatsinks of comparable dimension, and 40% better than cast structures.
Pinbloc heat sinks can be round, square, rectangular and even customised irregular shapes. For any base size the pins can be cut to a preferred length.

Applications for Pinbloc heat sinks are many and varied but IC and LED cooling are the most popular.
