Sony's recently launched flagship smartphone, the Sony Xperia Z2, reportedly features liquid heat-pipe cooling technology to prevent it from overheating in adverse conditions.
This liquid heat-pipe cooling technology is said to be rarely used in a smartphone, making Sony Xperia Z2 the second smartphone to carry such technology after Japan-based firm NEC's MediaS X06E smartphone, reports DigiTimes.
It has been also understood that as compared to PC and laptop heat pipes, which range from 0.8mm to 2mm, the liquid heat pipe placed inside the Sony Xperia Z2 is as thin as 0.6mm and is said to have better heat-dissipation effect than graphite carbon fibre sheets.
The liquid heat pipes work in a very simple process. When the lower end of the pipe is exposed to heat, the liquid coolant inside it starts to vaporise and reaches the top most part, where the vapour cools down and condenses. The condensed liquid then trickles down due to gravitational pull and again converts into vapour.
Additionally, it is being reported that some Sony Xperia Z2 users in Singapore have been complaining about their smartphones overheating while shooting 4K videos. Sony has replied to complaints and has recommended users to utilise a high capacity SD card.
"We are aware of some users encountering issues when shooting 4K video for extended periods. Shooting movies in high quality 4K resolution can make significant demands on your phone's processor and battery life, as well as phone memory. Therefore for the best experience, we recommend you install a high capacity SD card (Xperia Z2 can take a card up to 128GB) and shoot 4K video in short bursts of no longer than a few minutes at a time," says Sony, as reported by Xperia Blog.
