Liquid metal can be driven by the magnetic field of the motor stator to induce current with no dynamic seal problem. In the present study, a shaft cooling structure of a motorized spindle with Galinstan liquid metal as the working fluid was designed and the heat transfer perfo...
Here, we demonstrate an integrated liquid cooling system by utilizing a small droplet of liquid metal Galinstan, which is placed over the hot spot. Energizing the liquid metal droplet with a square wave signal creates a surface tension gradient across the droplet, which induces Marangoni flow over...
liquid metal, surface topology, interfacial tension, and diameter of thenozzle tipwere the key parameters that determined the resolution of the resulting patterns.Fig. 4E demonstrates an EGaIn pattern with a 200μmline width, with covering the pattern by additional PDMS after cooling below the ...

Analyses of conventional microchannel and microgap cooling show that galinstan, a recently developed non-toxic liquid metal that melts at -19掳C, may be more effective than water for high flux thermal management applications. This is because its thermal conductivity is nearly 28 times that of ...
Galinstan, a gallium, indium, and tin eutectic, may be utilized for single-phase liquid metal cooling of microelectronics due to its subambient melting temperature and high thermal conductivity. This paper describes the fabrication and assembly of water-based microchannel and Galinstan-based minichannel...
According to the present invention, the method to remove an oxide film on the surface of liquid metal using a coplanar microfluidic channel comprises: a step of applying a polydimethylsiloxane (PDMS) solution on the top of a microfluidic channel mold after the microfluidic channel mold is ...
Two-phase modelMelting behaviorMini/microchannel cooling performance can be improved with microencapsulated phase change material (MPCM) slurry as coolant by utilizing latent heat absorption capacity of MPCM. Compared with existing water, using liquid metal (LM) as basefluid can combine the advantages ...
