Scientists from City University of Hong Kong and Huazhong University have made a breakthrough in the field of processor cooling by creating a unique passive device. Based on the use of salt water, this device not only cools the processor, but also refills itself with moisture from the air, thanks to which the processor can work a third more efficiently. The system, called HSMHS, is impressive in its performance: it contains lithium bromide salt inside a porous membrane, which ensures efficient evaporation and, as a result, cooling.
This discovery is an important step in thermal management, especially with the rapid advancement of electronics and the increased heat generated by modern processors. Traditional cooling methods often require an external energy source and can be inefficient or harmful to the environment. In contrast, the developed device operates without external energy and without mechanical components, which makes it more durable and reliable, as well as more resistant to malfunctions.
This cooling system is especially useful for data centers and computer servers, where it is necessary to process huge volumes of data and maintain processors in optimal thermal conditions. With such a device, they can significantly reduce energy consumption and improve their environmental sustainability. Given the recent focus on environmental sustainability and energy efficiency, the discovery also opens up new prospects for the green technology field.
