Plastic Heat Sink Material

Aluminium alloy 1050a has one of the higher thermal conductivity values at 229 w m k but is mechanically soft.

Plastic heat sink material.

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. 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. This blend of quartz dust and acrylic resins offers the appeal of stone for less quality. In this study a heat sink was designed in 3d cad to cool a dual core host processor. 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.

The most common heat sink materials are aluminium alloys. More expensive than steel and solid surface sinks. The material of the heat sink plays an instrumental role in determining the efficiency of a heat sink. 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.

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. Now the million dollar question. The stated thermal properties of engineered graphite foams have enhanced their consideration as heat sink materials. 3 12 14 imagine if all the metal components of the common light fixture could be consolidated to just a few plastic parts.

Light weight 3d printed heat sinks heat sink performance is dominated by surface. Until fairly recently that is. Heat sinks and other heat removal applications are among the last areas where thermoplastics inherent thermal insulators have yet to replace metals. The performance of both an aluminum and copper design was then evaluated using cfd.

Elk grove village il. Which material should be used for heat sinks. Laboratory tests of copper aluminum and graphite foam. In the two polyone case studies this certainly proved true.

Aluminium alloys 6060 and 6063 are commonly used with thermal conductivity values of 166 and 201 w m k respectively. Manufacturers typically build heat sinks from die cast aluminum effective but costly to buy and work with. The values depend on the temper of the alloy.
