Hi it’s Steven Mill, last time I wrote about Magneto-electric Hexaferrite Films and their Applications in Electrical Devices. Today I’m still in the “magnetic” topic applied to heat dissipation, so here’s my contribution to the community.


Dissipation of heat in electrical systems and power generators has always been a great challenge. This is because, without proper dissipation of heat, an electrical system will become vulnerable to potential damage and malfunction issues.

In most parts of the world, cooling is mainly done by pumping cold water through pipes to remove undesirable heat. However, research is being carried out to introduce a cooling method that is much better, effective and cheaper than this primitive technique.

Research teams at MIT and in Australia successfully developed one such method that involves the use of magnetic nanoparticles. This superb technology is very effective and can be used to dissipate heat from simple electrical systems to even a nuclear reactor.


Warmth, cold, humidity: the proper atmosphere inside the enclosures

Most of the electrical panels and switchboards don’t need any thermal management for their internal atmosphere. The variation range of their internal temperature remains acceptable through the seasons and stays within the limitations imposed by the incorporated devices. However, some electrical switchboards should deal with extremely cold temperatures (technical rooms in the mountain) or with very warm or humid atmospheres (installations in Africa, in the Far East,…). Without going that far, some electrical switchboards contain a high density of power electronics devices. These electronic devices are more and more compact and generate a high level of heat dissipation. It is particularly true as examples for transformers, and for variable speed drives too. This situation is also frequent in little or big computing rooms. So, what are the solutions for electrical switchboards? (more…)
