Let us consider the major types namely active heat sinks and passive heat sinks.
Different types of heat sinks.
Types of heat sink active heat sink.
They are relatively inexpensive once a design is made the manufacturing is highly automated and in most cases aluminum is the material used.
The picture is an example of a heat sink that has both active and passive cooling mechanisms.
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.
When the heat sink utilizes fan hsf it is active heat sink.
Extruded heat sinks come at a low cost and custom specifications can be easily manufactured.
The heat sinks are classified into different categories based on different criteria.
The process is useful for most applications.
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.
Extruded heat sinks are the utility infielder of our industry.
There are two distinct types of convection.
Active heat sinks are used in liquid cooling system.
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.
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 does not utilize a fan it is passive heat sink.
Let s take a look at 6 common heat sink types.
Some types of heat sinks such as bonded fin can be made of both materials.
Heat sinks categorized by use of water.
A heat sink is a device that incorporates a fan or another mechanism to reduce the temperature of a hardware component e g processor.
The performance of extruded heat sinks can range from low to high.
This utilizes power for cooling process.
There are two heat sink types.
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.
1 extruded heat sinks.
Extruded stamped bonded fin and folded fin.
Solid metal heat sink.
One for the base and the other for the fins.
