Canon Has Designed a Magnetic Liquid Cooled Camera

    Canon has patented a design for liquid iron cooled mirrorless cameras. The designs indicated that the liquid would be moved around inside the camera using a series of magnets.

    Originally filed with the US Patent Office in February but published on August 18, patent – US number 20220264767 as noted by Canon Watches – describes a device that circulates magnetic fluid through the camera body to move heat away from this part of the camera and to another area where it is cooled.

    The system uses a combination of gravity and magnets to move liquid around the camera and “smooth” the fluid to move heat away from critical components and cooled through a seemingly located in the handle of the camera. Since the liquid cooling system requires some space to function properly, the space between the lens mount and the handgrip seems to be a bit wider than on current Canon mirrorless cameras or other models. previous DSLR cameras.

    The patent describes a system that pulls the tip away from the sensing area, down a conduit that moves the now heated magnetic fluid (and therefore iron) to the right and up the clamp where it is. cooled and then returned to the sensing area.

    Liquid cooling is nothing new, and many high-end PCs use this concept in place of fans to keep modern CPUs cool during heavy workloads. The idea of ​​using this concept in cameras is not new either. At the end of 2020, Matthew Perks from Do-it-yourself privileges built a water-cooled unit for his Canon EOS R5 camera. The camera, which is notorious for overheating when shooting at the highest resolution, can shoot at unlimited 8K thanks to liquid cooling.

    It’s not clear if Canon credited the idea when creating the design or if they worked on the liquid-cooled camera concept, but Canon filed an initial patent in February 2021 in Japan – after when Perks announced. video.

    Either way, the idea of ​​liquid cooling has been taken by Canon to another level with the integration of black liquid. There have been a few studies looking at different forms of magnetic refrigeration and liquid iron over the past few years, but the concept is not universal. Not only is Canon trying something on the bleeding edge of cooling technology, but it also needs to miniaturize it for use in a handheld device. The idea sounds promising, but it could very well be a while before the technology hits the market – if at all.
