The Future of Heat Sink

A heat sink is a passive heat exchanger that removes heat from a surface by conduction and dissipates it into the surrounding atmosphere. In electronics, a heat sink is typically a solid block of copper or aluminum with multiple heat sinks that increase the available surface area for heat transfer. With the never-ending quest to package more processing power into a more diminutive form, heat sink innovation is more critical than ever.

With the development of technology, the production process of heat sinks, as well as the use of materials, will continue to progress. Although we have not been able to determine the future of heat sinks in the end what will be, according to the technology available and the direction of research and development of significant heat sink brands, we can also make some simple predictions style of heat sinks, the following CPU heat sink manufacturer Coolsolte to talk to you about The future development of the radiator.

The future development of the radiator

Regarding radiators, researchers have been working for years on some exciting materials that could be game-changers. As I promised earlier, here are some more exotic materials in the field of heat sink design.

Carbon nanotubes (CNTs) have impressive electrical and thermal properties (thermal conductivity of 3000-6000 W/mK), so it's not surprising that researchers are experimenting with CNT heat sinks and copper CNT composites. Sadly, it will be some time before they are commercially available.

Diamond heat sinks are already available. Metal-diamond composites have a reduced coefficient of thermal expansion (6-12 ppm/K) and high thermal conductivity (300-650 W/mK).

Graphene is another carbon-based metamaterial that has attracted scientists. Here is a paper on graphene-carbon-metal composite films for flexible heat sinks.

HOPG (highly ordered pyrolytic graphite) is an anisotropic material with thermal conductivity of about (2000 W/mK).

The primary trend in improving heat sink materials is to use old-fashioned copper or aluminum and to dope the metal matrix with a high thermal conductivity metamaterial (usually carbon). While it is impossible to predict which of these materials will dominate the future of radiators, one thing is always sure: the best thermal management solutions take a holistic approach, combining the radiator with other cooling technologies (such as heat sinks, heat pipes, and steam chambers.

Regardless of which cooling method or heat sink you want, the right ECAD/MCAD tool will help you design your power electronics heat sink and implement the best cooling strategy. If you have stepped DFX, IDX, or IDF files of standard or custom heat sink, you can import these models into OrCAD and merge them into your board design. You can also add fans and support electrical components as needed. To verify the effectiveness of the heat sink, it is essential to use the appropriate simulation tools.

Whether you are developing a high-power device that requires extensive cooling or a more traditional electrical design that requires a conventional device, Cadence's suite of design and analysis tools will meet all your needs. With OrCAD, you will have the layout tools necessary to consider any thermal issues in your electrical designs.
