Different Types Of Heat Sinks

One for the base and the other for the fins.

Different types of heat sinks. Extruded heat sinks come at a low cost and custom specifications can be easily manufactured. There are two distinct types of convection. Heat sinks categorized by use of water. Let us consider the major types namely active heat sinks and passive heat sinks.

The process is useful for most applications. Some types of heat sinks such as bonded fin can be made of both materials. They are relatively inexpensive once a design is made the manufacturing is highly automated and in most cases aluminum is the material used. Here in part 1 we ll talk about the following heat sink types.

The picture is an example of a heat sink that has both active and passive cooling mechanisms. Types of heat sink active heat sink. There are two heat sink types. Let s take a look at 6 common heat sink types.

The majority of heat sinks are made from extruded aluminum. Extruded heat sinks are the utility infielder of our industry. Natural convection where the movement of the fluid particles is caused by the local changes in density due to transfer of heat from the surface of a solid to the fluid particles in close proximity. Pin straight and flared fin a pin fin heat sink is a heat sink that has pins that extend from its base.

Among the different types of heat sinks two phase forced convection cooling of high heat flux high power electronic devices is one of the most effective means of thermal management. A heat sink is a device that incorporates a fan or another mechanism to reduce the temperature of a hardware component e g processor. Solid metal heat sink. Active heat sinks are used in liquid cooling system.

Extruded stamped bonded fin and folded fin. The performance of extruded heat sinks can range from low to high. This utilizes power for cooling process. 1 extruded heat sinks.

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. The primary mechanism of heat transfer from the heatsink is convection although radiation also has a minor influence. In most of computer processor a fan is attached just above the heat sink. When the heat sink utilizes fan hsf it is active heat sink.

When the heat sink does not utilize a fan it is passive heat sink.
