The shape of the heat sink

Fin shape


now that is to expand the area of the radiator, so how to maximize the surface area, is the material is decided the design of the important key, ordinary heat sink is die casting, the shape of the common leek glyph in just a few more leaves, the cooling effect of cooling fin is the most common, more high-grade heat sink is used aluminum mold after lathe cutting, after cutting the shape of a multiple dentate cylinder, the heat sink, commonly used in high-end graphics CARDS and some of the original machine. Fin shape to the great influence of the heat dissipation effect, in the same volume of cases, if the heat sink has the more the number of fins or dentate cylinder, then the surface area of affirmation. Even made some good heat sink, using a piece of metal plate and lined with very thin heat dissipation fins design, maximize the expanded surface area, but in the case of attaches great importance to the cooling area, good heat sink can't ignore the thickness of the metal plate at the bottom of the base, must guarantee a certain thickness, usually can make the heat conduction effect is better.
