Plastic Heat Sink Material

In this study a heat sink was designed in 3d cad to cool a dual core host processor.

Plastic heat sink material.

Light weight 3d printed heat sinks heat sink performance is dominated by surface. 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. The performance of both an aluminum and copper design was then evaluated using cfd. Laboratory tests of copper aluminum and graphite foam.

The most common heat sink materials are aluminium alloys. 3 12 14 imagine if all the metal components of the common light fixture could be consolidated to just a few plastic parts. Elk grove village il. The material of the heat sink plays an instrumental role in determining the efficiency of a heat sink.

The values depend on the temper of the alloy. Until fairly recently that is. Aluminium alloy 1050a has one of the higher thermal conductivity values at 229 w m k but is mechanically soft. 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.

This blend of quartz dust and acrylic resins offers the appeal of stone for less quality. Manufacturers typically build heat sinks from die cast aluminum effective but costly to buy and work with. More expensive than steel and solid surface sinks. This innovation allows for plastic components that match the heat removal of metals but with reduced weight manufacturing cost and more design freedom.

Aluminium alloys 6060 and 6063 are commonly used with thermal conductivity values of 166 and 201 w m k respectively. In addition the soft material allows for the elimination of thermal interface materials in many. Which material should be used for heat sinks. In the two polyone case studies this certainly proved true.

Modifying plastics to improve their thermal conductivity is a burgeoning area of opportunity for a handful of compounders. Can be damaged by extreme heat price. 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. Now the million dollar question.

Heat sinks and other heat removal applications are among the last areas where thermoplastics inherent thermal insulators have yet to replace metals. 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. In computers heat sinks are used to cool cpus gpus and some chipsets and ram modules.
