Engineer has developed a new method of overheating redundant heat

The researcher has developed a planar bridge heat diode that allows you to effectively control the thermal regime of electronics, an airplane and even the spacecraft.

The team under the leadership of the Association of the Department of Mechanical Engineering of Polytechnic University Virginia Jonathan Boreiko created a device of two copper plates in a hermetic medium separated by microscopic gap. One plate has a fityl structure to hold water, and the other is covered with a water-repellent layer.

When water on the absorbent surface heats up, it begins to evaporate. When passing steam through a narrow gap, it is cooled and condensed on the hydrophobic side. These drops grow large enough to «overlap» the gap, and again suck in the wick, starting a new cycle.

If the heat source is located with a hydrophobic side, then the pair cannot form, since water remains in the wick. Therefore, the device can only carry out in one direction.

In practice, when the diode is connected to the overheating object, the heat released is transmitted through the conductive plate to the water, which turns into steam and removes from the source. The hydrophobic non-conductive side prevents heat from entering through air or other heat sources that can be nearby, allowing a diode to control heat only from its main object.
