Samsung engineers explain the Galaxy S7 and Galaxy S7 edge cooling system

The Galaxy S7 and Galaxy S7 edge aren’t the first smartphones to feature a liquid-based cooling solution, but Samsung’s latest flagships do carry out the cooling procedure in the smallest such setup seen on a mobile device. That’s just one interesting nugget the company’s engineers have shared in Samsung’s latest post about what makes the Galaxy S7 and Galaxy S7 edge so special.

Samsung highlighted the thermal cooling solution on the S7 lineup at the devices’ announcement, and it is now sharing what makes the solution stand out. The heat pipe on the S7 and S7 edge is only 0.4 mm in diameter, making it the smallest yet on a smartphone. The heat pipe – or the thermal spreader – “uses changes in the phases of water to radiate heat.” The water inside the solution absorbs the heat produced by the device and turns into steam, which is then dissipated via the heat pipe.

This steam then turns back into water, and in turns fuels the constant heat dissipation process. As the post explains, the physical cooling system works hand in hand with software algorithms to keep the S7 and S7 edge running cool. It is rather interesting to see how it all goes down inside devices that are so small and compact. The source link has the full rundown, so go ahead and find out how those powerful chipsets inside the S7 and S7 edge are kept in check.
