Here in part 1 we ll talk about the following heat sink types.
Different types of heat sinks.
The primary mechanism of heat transfer from the heatsink is convection although radiation also has a minor influence.
Extruded heat sinks are the utility infielder of our industry.
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.
Let us consider the major types namely active heat sinks and passive heat sinks.
The heat sinks are classified into different categories based on different criteria.
Pin straight and flared fin a pin fin heat sink is a heat sink that has pins that extend from its base.
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 majority of heat sinks are made from extruded aluminum.
One for the base and the other for the fins.
1 extruded heat sinks.
Heat sinks categorized by use of water.
Solid metal heat sink.
The picture is an example of a heat sink that has both active and passive cooling mechanisms.
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.
Let s take a look at 6 common heat sink types.
The performance of extruded heat sinks can range from low to high.
There are two distinct types of convection.
Extruded stamped bonded fin and folded fin.
When the heat sink does not utilize a fan it is passive heat sink.
Active heat sinks are used in liquid cooling system.
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.
In most of computer processor a fan is attached just above the heat sink.
The pins can be cylindrical elliptical or square.
Types of heat sink active heat sink.
Extruded heat sinks come at a low cost and custom specifications can be easily manufactured.
The process is useful for most applications.
