a cooling liquid moves automatically (and bi-directional) on a heated serrated surface.
from zdf.de joachim bublath [in german]

Transcript in English:
"... When such a computer runs, high temperatures appear in such microchips. Here they are already stacked one above the other to divert the heat. When one wants to cool such an element, a microscopic small pump is needed. And one idea is derived from a principle you probably all know already. When you have a hot cooking plate and you put water on it, then, as you can see, these droplets start to dance, run over the cooking plate. This happens because under the water droplets a cushion of steam is being built. And on this steam cushion the droplets can move along. And it was this idea that a scientist took up to develop a mini pump for electronics. We can have a look at the idea. As you can see, on a saw-toothed structure there's a droplet moving. This saw-toothed structure is being heated and as such a steam cushion is being created and you can see how the droplet crawls upwards on its own. When the surface is horizontal and flat, it comes to rest, only in the saw-toothed structure it can move itself forward. And now imagine that this is a cooling liquid that is being moved forward automatically by the saw-toothed structure."

  • ich denke durch das Dampfpolster kann die Kühlflüssigkeit nicht so effektiv Wärme aufnehmen, weil Dampf schlecht wärme leitet. außerdem ist es eher unpraktisch, wenn man dem system ständig Kühlflüssigkeit zufügen muss, weil die verdampft, und wohlmöglich an einem unpraktischen ort kondensiert

  • Währe net schecht, wenn du diese mal hochladen könntest, wenn du Zeit hast. mfg

  • Yo, hab noch einiges auf video=)

  • hallo er ist Physiker!! Von den ganzen koffern im tv ohne jeglicher mindestausbildung die wissenschaftssendungen moderieren, halte ich absolut null.

  • Hat jemand das alte Intro von Joachim Bublath aus den 80ern (Sendung: "Aus Forschung und Technik")?

  • die Sendung ist sehr geil, schade dass nur einmal im Monat und dann nur ne halbe Stunde:(

  • Bublath ist wirklich sehr gut..

    Seine Sendungen sind neutral und wirklich gut gemacht.

    Empfehlung: Joachim Bublath - Verblödet Deutschland...

    Zeigt u.a. Bildungsprobleme auf.

  • Amazing. What an idea!
