All purpose aluminium heat sink. Suitable for subwoofer amplifiers, electronic applications, PC mounts, Power Supply etc. Specifically designed fins to get maximum surface area and thermal conductance. The heatsink section profiles have been designed to provide an optimum fin profile for a given fin height, length and convection condition. Adequate section thicknesses are provided to maintain conservative temperature gradients across all heatsink surfaces and ensure ample mechanical strength which is necessary for mounting components.
