But a new patent offers some insight into how Microsoft plans to cool both devices. According to a patent released on November 21, Microsoft plans to use vapour chamber cooling technology to cool it, but extend it over the hinges to ensure equal cooling on both sides of the device.

The exposed examples relate to heat transfer devices including vacuum cavity average heat plates and flexible hinges. A public example provides an electronic device consisting of the first and second parts, which are connected by the hinge area, and the vacuum cavity heat plate, which extends from the first part to the second part and passes through the hinge area. The second layer containing titanium is connected to the first layer to form a vacuum cavity average heat plate, the working fluid in the vacuum cavity average heat plate, and the third layer containing titanium between the first layer and the second layer, the third layer contains one or more working fluids constructed as conduction characteristics by capillary action.
