Heat Sink Fin Types

The pins can be cylindrical elliptical or square.

Heat sink fin types.

These are made by bonding individual fins of a metal to the base of a heat sink. Heat sinks categorized by use of water as clumsy as this category might sound it really just includes solid metal heat sinks assemblies heat sinks using two phase devices and pumped liquid heat sinks. One for the base and the other for the fins. They are produced from a solid block of metal.

A heat sink s fin style can significantly influence its ability to release thermal energy into the environment. However fin style is generally subject to the shape of the heat generating component. 3 skived heat sinks. These bga heat sink devices mount with ez snap mounting clips and or thermal tape to provide optimum cooling for various package sizes and airflow.

Radian s bga aluminum plate fin designs are high efficiency heatsink cooling products which are ideal for linear air flow environments. These are frequently used for physically large applications that require sensible performance like electric welding and dc dc brick applications. Some types of heat sinks such as bonded fin can be made of both materials. This utilizes power for cooling process.

But it is more expensive than aluminum. Citation needed a second type of heat sink fin arrangement is the straight fin. Active heat sinks are used in liquid cooling system. These heat sinks offer high design flexibility and you can achieve high fin density.

Aluminium heat sink with high efficiency cooling fins. Inverted fins cavities edit open cavities are defined as the regions formed between adjacent fins and stand for the essential promoters of nucleate boiling or condensation. A pin fin heat sink is a heat sink that has pins that extend from its base. In most of computer processor a fan is attached just above the heat sink.

When the heat sink does not utilize a fan it is passive heat sink. A pin is one of the more common heat sink types available on the market. Heat sinks produced through this method are normally made from copper. For example a proper design would utilize a radial fin style when cooling a cylindrical shape as opposed to a flat straight fin heat sink.

These run the entire length of the heat sink. Types of heat sink active heat sink. When the heat sink utilizes fan hsf it is active heat sink.
