Do you believe emerging cooling technologies will effectively reduce the energy demands of large data centers?
Researchers in Japan and Germany have developed an elastocaloric cooling prototype using titanium-nickel alloy films. The system generates 2.09 milliwatts of cooling power without the need for a conventional motor.
Why it matters
Data centers currently require substantial electricity and water for cooling, necessitating more efficient alternatives. This new technology could eventually reduce the environmental footprint of computing infrastructure.
The system utilizes a thermal actuator made of shape memory alloy film to generate the mechanical force required to manipulate the refrigerant film. This cycle involves precise stages of heating, deformation, cooling, and film recovery.
The players
Nature Energy
This is a monthly peer-reviewed scientific journal that publishes high-quality research on energy-related topics.
The details
The cooling unit works by manipulating titanium-nickel alloy films through a series of deformation and recovery cycles. By eliminating the conventional motor, the design aims to simplify the cooling process for compact devices.
