Until fairly recently that is.

Plastic heat sink material.

Elk grove village il. The metal heat sinks represent a substantial part of the cost of led luminaires. 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. The performance of both an aluminum and copper design was then evaluated using cfd.

Can be damaged by extreme heat price. Manufacturers typically build heat sinks from die cast aluminum effective but costly to buy and work with. 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. Laboratory tests of copper aluminum and graphite foam.

Heat sinks and other heat removal applications are among the last areas where thermoplastics inherent thermal insulators have yet to replace metals. This innovation allows for plastic components that match the heat removal of metals but with reduced weight manufacturing cost and more design freedom. Aluminium alloy 1050a has one of the higher thermal conductivity values at 229 w m k but is mechanically soft. 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 this study a heat sink was designed in 3d cad to cool a dual core host processor. 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. In the two polyone case studies this certainly proved true. In addition the soft material allows for the elimination of thermal interface materials in many.

Light weight 3d printed heat sinks heat sink performance is dominated by surface. The most common heat sink materials are aluminium alloys. Modifying plastics to improve their thermal conductivity is a burgeoning area of opportunity for a handful of compounders. Which material should be used for heat sinks.

In computers heat sinks are used to cool cpus gpus and some chipsets and ram modules. 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. More expensive than steel and solid surface sinks.

The values depend on the temper of the alloy. A heat sink also commonly spelled heatsink is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium often air or a liquid coolant where it is dissipated away from the device thereby allowing regulation of the device s temperature. Aluminium alloys 6060 and 6063 are commonly used with thermal conductivity values of 166 and 201 w m k respectively.
