Ats engineers used analytical modeling and cfd simulations to examine the thermal performance of two aluminum heat sink designs.
Most efficient heat sink design.
They are produced from a solid block of metal.
Bonded fin heat sinks use separate base and fins assembled to form a heat sink figure 3.
One of the most critical parameters of a heat sink is the material from which it is constructed.
When designing a heat sink for a cpu cooler what is the optimal design.
Analysis demonstrated that the design with heat pipes running above the components kept junction temperatures within 2 c of the original.
These heat sinks offer high design flexibility and you can achieve high fin density.
Bonded fin heat sinks generally offer moderate performance and come at a high cost.
One with heat pipes that stopped at the edge of the components and the other with heat pipes that ran above the components.
Heat sinks produced through this method are normally made from copper.
Increases in cooling surface area of 200 to 300 allow significant decreases in heat sink volume.
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.
Bonded fin heat sinks.
These designs are designed for thermal efficiency but contained by manufacturing process.
Some of the more common construction materials for heat sinks are aluminum and copper.
In computers heat sinks are used to cool cpus gpus and some chipsets and ram modules.
