When the heat sink does not utilize a fan it is passive heat sink.
Different types of heat sinks.
Extruded heat sinks are the utility infielder of our industry.
The process is useful for most applications.
This utilizes power for cooling process.
When the heat sink utilizes fan hsf it is active heat sink.
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.
Here in part 1 we ll talk about the following heat sink types.
There are two distinct types of convection.
They are relatively inexpensive once a design is made the manufacturing is highly automated and in most cases aluminum is the material used.
One for the base and the other for the fins.
The heat sinks are classified into different categories based on different criteria.
The primary mechanism of heat transfer from the heatsink is convection although radiation also has a minor influence.
Active heat sinks are used in liquid cooling system.
Let us consider the major types namely active heat sinks and passive heat sinks.
Pin straight and flared fin a pin fin heat sink is a heat sink that has pins that extend from its base.
There are two heat sink types.
Some types of heat sinks such as bonded fin can be made of both materials.
Solid metal heat sink.
Heat sinks categorized by use of water.
Extruded heat sinks come at a low cost and custom specifications can be easily manufactured.
The pins can be cylindrical elliptical or square.
The majority of heat sinks are made from extruded aluminum.
1 extruded heat sinks.
The performance of extruded heat sinks can range from low to high.
A heat sink is a device that incorporates a fan or another mechanism to reduce the temperature of a hardware component e g processor.
Types of heat sink active heat sink.
The picture is an example of a heat sink that has both active and passive cooling mechanisms.
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 pin is one of the more common heat sink types available on the market.
Extruded stamped bonded fin and folded fin.
