In general, everything that is hot but shouldn’t be should be placed on a heat sink. In order to safeguard the entire system and its components heat dissipation is required for any equipment or device having a heat source whether it be mechanical electrical chemical nuclear solar or frictional.

Heat sinks are frequently used in electronics to provide cooling for battery packs IT telecommunication cooling, and controllers for electric vehicles. As a result it is clear that heat sinks are used in a variety of settings from massive power equipment to small electronics like laptops cellphones and tablets.

Extruded heat sinks also go by the names extruded aluminum heat sinks and heat sink extrusions. These heat sinks have attractive looks are lightweight have strong heat dissipation capabilities and have an energy saving effect. Here we will learn more about the aluminum extrusion heat sinks and the working technique.

Working Of The Aluminum Extruded Heat Sinks

  • The typical high power heat sink and heat sink system is the aluminum extrusion heat sink.
  • The heat sink surface area can be increased by these intricate fins which also speed up and lower the cost of manufacturing aluminum blocks.
  • Simply defined the process of producing an extruded heat sink material using aluminum heat sink extrusion technology involves heating aluminum ingots to a temperature between 520°C and 540°C at a high temperature and high pressure.
  • The extruded aluminum heat sink that we frequently see is then produced after numerous cuts are made to the heat sink extrusion material.
  • The aluminum heat sink material AL6063 which has good thermal conductivity and machinability is frequently utilized.

Benefits Of Aluminum Extruded Heat Sinks

Usage In Industries

A wide variety of industries employ aluminum extrusion heat sinks because of their superior thermal conductivity, corrosion resistance, and long service lives.

Longer Life

The aluminum alloy material can develop a thick oxide film, which can be utilized for a long period to heat water or car water tanks with a pH of 9. The aluminum heat sink can be utilized for a longer time in various materials with a pH of up to 12 owing to its specific surface treatment.

Simple Installation

It has straightforward installation and easy maintenance. The cross section of the aluminum heat sink is wide and normal because the aluminum alloy has the least density and can be processed into pieces of multiple forms and needs making it simple for surface treatment and product assembling. It may be installed right there on the job site, which will save you a lot of installation money.


This is lightweight and simple to move and install. The weight of the aluminum heat sink is just one-eleventh as notable as the iron heat sink when the dissipation of heat is the same as a third of the copper heat sink and a sixth of the steel heat sink.

Energy Conserving

Energy conservation lower consumption and affordable use are some benefits. The aluminum heat sink dissipates heat 2.5 times faster than the cast iron radiator when the distance between the radiator’s inlet and outlet and the temperature of heat conduction is equal.

Concluding Remarks

Because of their high strength excellent water and air tightness, outstanding heat conduction, exquisite look, and ease of manufacturing, extruded aluminum heat sinks are utilized extensively. Aluminum heat sinks are currently utilized in a variety of products such as electronic electrical computer sunflower aluminum profile radiator electricity semiconductor heat sink profiles etc.
