The heat sink is a device that transfers heat generated from a device to a fluid that can be air or a liquid coolant, then this heat is dissipated away from the device, thereby maintaining the device’s temperature. There are several applications of heat sinks in different fields like natural systems, thermal management or machinery, etc.
If you are not as familiar with the technology world then still, heatsink extrusion will be very simple for you. For getting heat out of any device, a special algorithm is used that is named a heat sink. This technique works by increasing the quantity of liquid having low temperature and the working area of the device.
Types Based On the Manufacturing Process
Heat sinks are manufactured in different ways and by using different materials for manufacturing. Each Heat sink manufacturing process has its advantages as well as drawbacks. There are several ways by which Heat sinks are made, let’s take an overview of heat sink types:
Extruded Type Heat Sink
As mentioned in its name, extruded aluminum is being utilized in the manufacturing of extruded-type heat sinks. As aluminum comes with several features and benefits in different fields therefore it is the most demanding heat sink material. It makes this type of aluminum extrusion heat sink cost-effective and its manufacturing process has also become very easy.
Forged Type Heat Sink
This type of heat sink has been manufactured by compression of copper and aluminum. Same as extruded type heat sinks, this type also has wide application all over the market. They can be produced at minimal cost for large volumes and have a medium level of performance. However, the Forged Heat Sink offers limited design capabilities.
Bonded Type Heat Sink
Bonded Heat Sink is used for applications that require large-size heat sinks. Because of having different fins and base materials, this type of heat sink is in great demand. Moreover, rather than using only one fin material, fins made of both aluminum and copper can be employed.
In this way, just by adding a small quantity of weight, its thermal performance can be increased to an extent. But the thing to keep in mind is that this type of heat sink is expensive compared to other types.
Stamped Type Heat Sink
This type of heat sink is named stamped type heat sink because it contains such metal fins that are stamped and then welded at the base of it. They are usually demanding where low-power applications are practiced. As this type has the facility of easy production hence is considered a low-cost heat sink. It has the drawback of low performance.
Skived Type Heat Sink
Skived Heat sinks are normally made of copper. A single piece of metal is utilized in the manufacturing of this type of heat sink. Skived heat sinks provide significant levels of design flexibility and fin density. Hence, more surface area and heat dissipation opportunity is being taken due to it. Although, it allows desired working its heavyweight act as a drawback for it.
CNC Machined Type Heat Sink
As the most difficult geometries can be obtained through this procedure and it has the facility of high thermal conductivity. It means we have plenty of flexibility in our design. But, the thing that makes this type of heat sink less ideal and demanding is its high cost hence most industries can’t afford to buy it.
Materials Used In Heat Sink
Materials that are used in heat sinks are Aluminum and Copper. The aluminum extrusion heat sink is suitable for most purposes. The metal is light in weight and has an excellent level of heat conductivity. Copper heat sinks have better thermal conductivity than aluminum only left stand because of their cost and weight.
Final Wording
A heat sink is effective at extracting heat from different appliances. To enhance the performance and lifetime of a device, a heat sink extracts heat from its components.
