Heat Sink Material

The most common heat sink materials are aluminium alloys.

Heat sink material.

Heat sinks are usually made from aluminum or copper. The graphite heat sink s thermal performance was only 12 lower than aluminum at low flow rates. However the performance difference increased to 25 30 as the flow rate increased table 3. Aluminum heat sink material is aluminum alloy and aluminum alloy a relatively common heat sink manufacturing material in the current market which is more high quality aluminum alloy 6063 and 6061.

These heat sinks have flanges with mounting slots for installation in frames and. Aluminium alloys 6060 and 6063 are commonly used with thermal conductivity values of 166 and 201 w m k respectively. Each has its own advantages. For example some heat sink producers are bonding copper and aluminum together.

Let s talk about the main differences between them. A fan cools water as it moves through the tubes to dissipate heat. 1 1 8 5 32 1 8 chrome plated copper. In computers heat sinks are used to cool cpus gpus and some chipsets and ram modules.

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. Heat sinks are available at mouser electronics from industry leading manufacturers mouser is an authorized distributor for many heat sink manufacturers including aavid thermalloy advanced thermal solutions cts ohmite sensata te connectivity wakefield vette more. This behavior is evident in the table below and when comparing the different heat sink materials. Aluminium alloy 1050a has one of the higher thermal conductivity values at 229 w m k but is mechanically soft.

If replacing a kitchen sink you ll think about style size and perhaps most importantly material. In particular extruded aluminum heat sinks fit the needs of most projects. Although the heat dissipation performance is not as good as copper the heat dissipation coefficient can reach 201w. Aluminum is the most common material for heat sinks.

Heat sink material. The design consists mainly. Companies are constantly striving to find lighter more conductive materials to make efficient heat sinks. The values depend on the temper of the alloy.

Heat sinks are like any other product in the always advancing field of computers. They don t need to be made from just one material.
