One very effective way to produce high efficiency The new heat sink design obtains greater resist- heat sinks with low weight to heat radiation ratios ante to fin damage without loss in cooling surface is to bond formed aluminum tins to a thick alumi- by bonding an addition cooling surface of material num base plate. These bonded metal heat sink tins similar to the cooling tins to the unsupported edge are quite thin and sensitive to damage. of the heat sink fins. This makes a much more rigid box structure and adds heat sinking surface at the One way to protect the tins would be to add same time. sheet metal sides or a cover plate to protect the fins but these approaches end up reducing the available tin cooling surface area.
