The most interesting is the one that uses USB/Firewire ports as vents.
These ports would theoretically (while they're not being used, of course) help increase airflow to vital hot parts, so that you wouldn't have to create more vents on the other parts of the laptop. The downside is that if you're the kind of person who likes to plug everything in and fill up all the holes of your laptop all the time, you're cutting off potential ventilation.
Two of the other patents, one for sensing airflow and making adjustments automatically, and the other using heat-conductive hinge assemblies, seem more obvious and less innovative. The last, though, uses the Peltier effect which...
defines when an electrical current runs through the junction of two different metals. When electrons flow from a region of high density to a lower one, it allows them to cool. The application describes a "solid-state cooling mechanism" that would employ two sides to transfer heat away from the machine and help dissipate it.
So it allows additional cooling, but without having to employ more fans. Another way for the device to keep small and sturdy without cutting more holes and adding more air-pushing components.
