In many applications with high-performance FPGAs, power dissipation in excess of 30 W can occur. Since there is often very little space above the chip to ensure adequate cooling, the existing space must therefore be used as effectively as possible.
In this case, pin heatsinks in the form of Alutronic’s Powerblocs range, in combination with SEPA fans, come in handy, while also boasting low production costs. They are only 10 mm high together with a radial fan, and provide a cooling solution with a very low thermal resistance of 0,95 K/W. The fan is supplied with a tacho and PWM input, and features long-lasting Magfix bearing technology.
All parameters of the pin heatsinks – size, pin space, thickness of the base plate, height of the pins – can be adapted to reach the right compromise between the longest possible pins and a base plate that is not too thin. The base plate not only acts as a support for the pins and should therefore not bend easily, but it is also the heat spreader that draws the heat into the surface and thus distributes it over a wide area.
Alutronic specialises in customised ideas for these types of cooling solutions.
