Things about Heat sink

Heat sink

Useful qualities :

  • a heat sink is an object that disperses heat from another object.
  • heat sink has a thermal conductor
  • thermal conductivity, is how heat sinks transfer heat away from the computer’s processor.
  • Heat sinks are usually made of metal
  • The higher the thermal conductivity of the metal, the more efficient it is at transferring heat.
  • One of the most common metals used in heat sinks is aluminum.
  • One of the best and most common materials used to make heat sinks is copper. Copper has a very high thermal conductivity of 400 W/mK.
  • some heat sink producers are bonding copper and aluminum together. The design consists mainly of aluminum (for its lightweight properties) surrounded by a copper plate (for its high rate of thermal conductivity).
  • In October 2008, the firm Applied Nanotech announced that the future of heat sinks is an isotropic material called CarbAl. CarbAl is made up of 20 percent aluminum and 80 percent of two different carbon-derived materials with excellent thermal conductivity. Applied Nanotech was excited about the material because it has a thermal conductivity of 425 W/mK
  • Another material that’s gaining popularity with heat sink producers is a natural graphite composite material. It’s not as conductive as copper, but it’s close with a thermal conductivity of 370 W/mK. But the real advantage of graphite is its weight — it weighs just 70 percent of the weight of aluminum.
Looking for making a 3D sink by hacking a Hair Curler
  • an electrical resistor positioned inside them in order to generate heat.
  • a circuit board made of material that does not conduct electricity, is used to hold the electronic components such as capacitors and resistors that hold and manage the electrical charge.
  • Heat transfer elements inside the curlers for conducting heat from the resistors to the cylindrical walls include
    • a heat-sink, a device which transfers heat.
    • This surrounds the resistor and conforms to the inner surface of the hair roller.
    • These electronic components carry the heat of the resistors to the outer wall of the curler.
