Apple Considers Using Magnets to Cool Overheating Devices
Apple is exploring the possibility of using magnets to cool down overheating devices, such as the iPhone and iPad. The proposed cooling system would involve the circulation of liquid and the removal of heat through the use of magnets.
In today’s technologically advanced world, electronic devices, especially when subjected to intensive usage, are prone to overheating. For instance, leaving an iPhone on a car holder under direct sunlight can cause it to overheat and potentially shut down. This happens because the device is constantly working, receiving and displaying new data.
A recently issued patent by Apple, called “Liquid Heat Exchange Electronic Device,” aims to address this issue. Instead of cooling the device itself, the patent suggests a method of dissipating heat before components become damaged. The proposed cooling system includes a tube containing a liquid and a magnetic piston that moves within the tube under the influence of a magnetic field, thereby creating a circulation of the liquid.
Contrary to initial assumptions, the patent clarifies that this innovation is intended for all Apple devices, ranging from Macs to iPhones. Its purpose is to enhance user experience, prevent damage to components, and extend the lifespan of the device. While many devices already come equipped with fans for cooling, Apple’s new approach does not seek to undermine the advantages of fans. However, fans can generate noise and vibration, which are undesirable features for mobile devices.
Apple’s new proposal focuses on implementing a liquid heat exchanger to achieve these objectives. The patent describes different systems where magnets, electrodes, and power sources work together to create Lorentz power, which compels the conductive fluid to circulate within the tube. The patent is attributed to inventor Xiaoyi Huang.
