Different Types Of Heat Sinks

The pins can be cylindrical elliptical or square.

Different types of heat sinks.

The performance of extruded heat sinks can range from low to high. 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. The process is useful for most applications. This utilizes power for cooling process.

Here in part 1 we ll talk about the following heat sink types. A pin is one of the more common heat sink types available on the market. The heat sinks are classified into different categories based on different criteria. 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. When the heat sink utilizes fan hsf it is active heat sink. Let s take a look at 6 common heat sink types. 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.

There are two distinct types of convection. Solid metal heat sink. The picture is an example of a heat sink that has both active and passive cooling mechanisms. There are two heat sink types.

In most of computer processor a fan is attached just above the heat sink. The primary mechanism of heat transfer from the heatsink is convection although radiation also has a minor influence. The majority of heat sinks are made from extruded aluminum. Some types of heat sinks such as bonded fin can be made of both materials.

Types of heat sink active heat sink. Let us consider the major types namely active heat sinks and passive heat sinks. They are relatively inexpensive once a design is made the manufacturing is highly automated and in most cases aluminum is the material used. Heat sinks categorized by use of water.

Extruded heat sinks are the utility infielder of our industry. 1 extruded heat sinks. A heat sink is a device that incorporates a fan or another mechanism to reduce the temperature of a hardware component e g processor. When the heat sink does not utilize a fan it is passive heat sink.

One for the base and the other for the fins.
