Heat Sink Fin Types

In most of computer processor a fan is attached just above the heat sink.

Heat sink fin types. Aluminium heat sink with high efficiency cooling fins. 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. When the heat sink does not utilize a fan it is passive heat sink. These run the entire length of the heat sink.

These are frequently used for physically large applications that require sensible performance like electric welding and dc dc brick applications. These are made by bonding individual fins of a metal to the base of a heat sink. They are produced from a solid block of metal. Citation needed a second type of heat sink fin arrangement is the straight fin.

A pin is one of the more common heat sink types available on the market. A pin fin heat sink is a heat sink that has pins that extend from its base. The most common heat sink materials are aluminum alloy has one of the higher thermal conductivity values at 229 w mk but is mechanically soft. 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.

Types of heat sink active heat sink. Active heat sinks are used in liquid cooling system. A heat sink s fin style can significantly influence its ability to release thermal energy into the environment. One for the base and the other for the fins.

These heat sinks offer high design flexibility and you can achieve high fin density. The pins can be cylindrical elliptical or square. 3 skived heat sinks. But it is more expensive than aluminum.

Bonded fin heat sinks generally offer moderate performance and come at a high cost. Heat sinks produced through this method are normally made from copper. This utilizes power for cooling process. 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.

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. Radian s bga aluminum plate fin designs are high efficiency heatsink cooling products which are ideal for linear air flow environments. When the heat sink utilizes fan hsf it is active heat sink.
