The early Windows phone devices were liquid-cooled, sort of

Jim Lyon shares this story about early Windows phone devices:

I remember during early development of Windows phones, our solution to the overheating problems. You would get two cans of soda from the fridge, set one on the desk, set the phone on top of that, and set the other on top of the phone. You were then good for an hour or so. We probably had the only liquid-cooled phones on the planet.

    I used a similar method to cool down my Google Glass and unfortunately the bag containing the ice broke :-(

    I used this for my laptop when playing particularly taxing games. I would prop the laptop up and fill a plastic bag with ice then put the bag under it.

    There is a story from one of the Commodore 128 engineers from when they developing the computer, that the programmer of the CP/M for that computer used to put a metal cup with an ice over the 80 column video chip to have half an hour of development time.

      Perhaps that half hour time was how long it took for the humidity in the air to condense on the outside of the metal cup, drip down onto the circuit board, and short out the IC.

        It’s commodore, shorting out the IC would make it work better.

          Gotta love the TED chip in the plus 4/ 16. Even underclocked they didn’t last long.

    My laptop’s fan started misbehaving to the point where it did nothing to cool the laptop and my screen would go all white, so I aimed an external fan at the hottest part of the laptop. It worked long enough to order a new laptop.

    This is also used to cool down computer keyboards. Conversely, coffee is often used to warm up keyboards.

      And I don’t even like coffee.

  6. That’s induction-cooled, not liquid-cooled.

    But of course, since that type of cooling was not a feature of the phone itself, the phone was neither liquid-cooled nor induction-cooled. It had no cooling features.

      Hence why Windows Phone was never cool.

    I’ve done similar things with a regular Android phone – while playing certain games or playing content on a TV via a Slimport adapter the phone would get quite warm if the phone was charging at the same time. I was quite worried that this would cause the battery to wear out faster among other issues, so I’d get a regular zip-lock bag filled with room temperature water and place in under the phone. It worked really well because of the huge contact area and the fact that it takes a lot of heat to notably raise the temperature of a 100ml of water.

    Just put the whole phone in a beer fridge and you phase-change cooling!
