Heat Sink Fin Types

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.

Heat sink fin types.

Types of heat sink active heat sink. These are made by bonding individual fins of a metal to the base of a heat sink. However fin style is generally subject to the shape of the heat generating component. Some types of heat sinks such as bonded fin can be made of both materials.

These heat sinks offer high design flexibility and you can achieve high fin density. This utilizes power for cooling process. In most of computer processor a fan is attached just above the heat sink. Heat sinks produced through this method are normally made from copper.

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. Copper has around twice the thermal conductivity of aluminum and faster more efficient heat absorption. 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. Active heat sinks are used in liquid cooling system.

Aluminium heat sink with high efficiency cooling fins. Bonded fin heat sinks generally offer moderate performance and come at a high cost. Citation needed a second type of heat sink fin arrangement is the straight fin. 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.

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. They are produced from a solid block of metal. These run the entire length of the heat sink. The pins can be cylindrical elliptical or square.

A pin fin heat sink is a heat sink that has pins that extend from its base. One for the base and the other for the fins. 3 skived heat sinks. A pin is one of the more common heat sink types available on the market.

But it is more expensive than aluminum. When the heat sink utilizes fan hsf it is active heat sink. A heat sink s fin style can significantly influence its ability to release thermal energy into the environment.
