Heat Sink Fin Types

A heat sink s fin style can significantly influence its ability to release thermal energy into the environment.

Heat sink fin types. Active heat sinks are used in liquid cooling system. This utilizes power for cooling process. 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.

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. 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. They are produced from a solid block of metal.

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. However fin style is generally subject to the shape of the heat generating component. These are frequently used for physically large applications that require sensible performance like electric welding and dc dc brick applications. These heat sinks offer high design flexibility and you can achieve high fin density.

When the heat sink utilizes fan hsf it is active heat sink. 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. When the heat sink does not utilize a fan it is passive heat sink. Types of heat sink active heat sink.

3 skived heat sinks. One for the base and the other for the fins. The pins can be cylindrical elliptical or square. A pin is one of the more common heat sink types available on the market.

Radian s bga aluminum plate fin designs are high efficiency heatsink cooling products which are ideal for linear air flow environments. Bonded fin heat sinks generally offer moderate performance and come at a high cost. Copper has around twice the thermal conductivity of aluminum and faster more efficient heat absorption. In most of computer processor a fan is attached just above the heat sink.

Citation needed a second type of heat sink fin arrangement is the straight fin. Some types of heat sinks such as bonded fin can be made of both materials. Heat sinks produced through this method are normally made from copper.
