Keeping equipment cool

Stay cool

Cooling electronic equipment and its parts and components presents system designers and hardware developers with ever increasing challenges. Because not only is power throughput continually rising, but packing density, too, is increasing, allowing systems less and less space for cooling and heat dissipation.

It is therefore important to incorporate electronics cooling into the overall plan at an early stage in the design process.

Equipment level

Cooling from component to system level

This begins with the simulation of the thermal behavior of individual components such as processors, chips, LEDs or IGBTs. Depending on output, design and the materials used, heat generation can vary here, too, and can play a vital role in the placement of components within the device.

6SigmaET, now part of Cadence imports all the details of your individual components from your CAD data and combines them with the available datasheet values and a comprehensive material library. Components can be modeled accurately thanks to intelligent parametric specification, allowing for a realistic simulation of the heat generated.

This gives you the basis for an efficient thermal design – realistic and reliable.


Cooling entire systems

Interaction between individual components, their configuration within the equipment and additional features such as housing material obviously also play a key role here. This also applies to the type of usage: because whereas stationary electronic equipment is usually exposed to only slight temperature fluctuations, devices such as smartphones etc. are sometimes left to lie in the direct sunlight and can thus overheat more easily. When simulating complete systems, 6SigmaET, now part of cadence, also relies on your CAD data. The individual elements can be assigned different parameters, which results in a realistic model. In this way it is possible for 6SigmaET to produce simulations with detailed electronic equipment in a realistic environment with up to 700 million cells in acceptable computation times.
