Copper is always a preferred choice for heat sinks due to its cooling capacity being superior to aluminum; however, copper’s weight and cost limit the size, especially for large electronics systems.

many heat sinks are produced by an extrusion process. Thermal extrusions, as with most aluminum extrusions, are formed as two-dimensional parts along a length. Most extrusions are made in large ...

The heatsink chosen for this application is a gigantic cube of aluminum, most likely taken ... way [Eric] would have found a sufficiently large heat sink that would precisely fit the back of ...

This heavy-duty aluminum heat sink and ball-bearing fan, called the UNIVERSALHSF, fits the Intel PIII, Intel P4 up to 3.2 GHz, AMD Athlon XP 3000+, and AMD K7 and K8 CPUs. The extra-large aluminum ...

Above this base are fins or pins that provide a large surface area for heat ... Heat sinks – like this one from Okat – use basic physics: thanks to conductive materials such as aluminum ...

small, let's look at hot stuff. Here I have three aluminum objects. A large block, a small block, and a heat sink. Just for reference, the big block is about 14 centimeters long and the smaller ...
