Apple is Granted a Patent for a Future iPhone Heat Exchanger that uses a Magnet to Circulate Cooling Fluid
In a new report today by China's IT Home, they noted that according to the 3DMark Wildlife Extreme benchmark test results, the GPU performance of Samsung Galaxy S23 Ultra is better than that of iPhone 15 Pro Max. Further, test results show that iPhone 15 Pro Max users may experience a sudden drop in frame rate during gaming. Although the A17 Pro uses the latest 3nm process, it has low energy efficiency and lacks an adequate cooling system, making the device easily hot.
Today, the U.S. Patent and Trademark Office officially granted Apple a patent that relates to a heat exchanger and, more particularly, to a heat exchanger that uses a magnet to circulate cooling fluid that may be implemented in a future iPhone.
Liquid Heat Exchanger For Electronic Device
Apple's granted patent that was never made public before, generally relates to a heat exchanger and, more particularly, to a heat exchanger that uses a magnet to circulate cooling fluid.
In some examples, a system can include an electronic device and a cooling system configured to transfer heat from one component of the electronic device that can generate heat to a housing of the system (e.g., a housing of the electronic device).
In some examples, the cooling system can include a magnetic piston within a piston housing of the cooling system. The piston housing can be fluidly coupled to a pipe containing a fluid, such as water, for example.
In some examples, the cooling system can further include one or more electromagnetic coils coupled to a power supply (e.g., an AC power supply) that are configured to generate a magnetic field. The magnetic piston can move back and forth within the piston housing to cause the liquid to circulate in the fluid pipe, for examples. In some examples, the moving fluid can transfer heat between components of the system.
In some examples, the cooling system can include a magnet and one or more pairs of electrodes coupled to a power supply (e.g., a DC power supply) coupled to or in proximity to one or more pipes containing a conductive cooling fluid. The magnet, electrodes, and power supply can generate a Lorentz force that can cause the conductive cooling fluid to circulate within the fluid pipe. In some examples, the circulating fluid can transfer heat between components of the system.
Apple's patent FIGS. 3A-3B below illustrate an exemplary cooling system including a magnetic piston; FIG. 4A illustrates an exemplary cooling system that utilizes Lorentz force to circulate a conductive cooling fluid; FIG. 4B illustrates an exemplary Lorentz force generated by a current and magnetic field.
Apple's patent FIG. 2 above illustrates an exemplary system that can include a cooling system.
While the focus of the device is an iPhone, Apple makes it clear that the invention could also apply to all of their current devices: iPad, Apple Watch Vision Pro, Macs and possible future products including projectors, gaming consoles and more.
During Apple's iPhone event earlier this month, Ubisoft noted that the iPhone A17 Pro allowed them to push the quality of games. And with Resident Evil Village coming next month and Assassins Creed Mirage will be coming to iPhone in early 2024. This will be the first Time the console version of Assassin's Creed will be natively available on a smartphone. So looking to the future as processors and GPUs advance, the iPhone will need to have a superior cooling system to keep games playing at top performance.
