Plastic Heat Sink Material

The most common heat sink materials are aluminium alloys.

Plastic heat sink material.

Aluminium alloys 6060 and 6063 are commonly used with thermal conductivity values of 166 and 201 w m k respectively. The values depend on the temper of the alloy. In this study a heat sink was designed in 3d cad to cool a dual core host processor. This innovation allows for plastic components that match the heat removal of metals but with reduced weight manufacturing cost and more design freedom.

Which material should be used for heat sinks. Until fairly recently that is. In computers heat sinks are used to cool cpus gpus and some chipsets and ram modules. In addition the soft material allows for the elimination of thermal interface materials in many.

3 12 14 imagine if all the metal components of the common light fixture could be consolidated to just a few plastic parts. The metal heat sinks represent a substantial part of the cost of led luminaires. The material of the heat sink plays an instrumental role in determining the efficiency of a heat sink. Material suppliers believe that the use of plastic heat sinks would prove beneficial for the vast majority of led luminaires as they can reduce assembly costs increase design freedom and consolidate parts.

Light weight 3d printed heat sinks heat sink performance is dominated by surface. The stated thermal properties of engineered graphite foams have enhanced their consideration as heat sink materials. Elk grove village il. The performance of both an aluminum and copper design was then evaluated using cfd.

As an injection molding contractor with expertise in lighting components kruunutekniikka knew it could provide improved manufacturability and performance in led lighting by producing non metal heat sinks at scale. Heat sinks and other heat removal applications are among the last areas where thermoplastics inherent thermal insulators have yet to replace metals. Now the million dollar question. Laboratory tests of copper aluminum and graphite foam.

In the two polyone case studies this certainly proved true. This is because the thermal conductivity of the material that is being used to make the heat sink directly affects the dissipation capacity of the heat sink. More expensive than steel and solid surface sinks. This blend of quartz dust and acrylic resins offers the appeal of stone for less quality.

Every light fixture needs a way for the heat from the light source to escape the fixture a component commonly referred to as the heat sink. Manufacturers typically build heat sinks from die cast aluminum effective but costly to buy and work with. Can be damaged by extreme heat price.
