Heat Transfer Performance of Biphilic Surfaces With Diatomite‐Based Composite Coatings in a Closed Thermosyphon System

Heat Transfer, EarlyView.
ABSTRACT This study investigates the thermal performance of innovative biphilic boiling surfaces designed for CPU cooling applications using a two‐phase closed thermosyphon (TPCT) system. The surfaces were fabricated by applying composite coatings—comprising epoxy resin and diatomite particles functionalized with APTES and PFOTS silanes— onto Al1050 ...

Modeling and Optimization of the Immersion Evaporative Cooling Lithium‐Ion Battery System

Modelling and Simulation in Engineering, Volume 2026, Issue 1, 2026.
This paper focuses on the coupling mechanism, performance, and optimization of the immersion evaporative cooling lithium‐ion battery system (IECLBS). A novel dynamic coupling model is established based on the whole heat transfer path. We investigated the coupling mechanism of IECLBS by examining changes in the relevant parameters.

Characteristics of Enhanced Heat Transfer of Nanofluid in Microchannels Under Electric and Magnetic Co‐Excitation

Asia-Pacific Journal of Chemical Engineering, Volume 20, Issue 6, November/December 2025.
ABSTRACT Due to its small size, microchannel heat exchangers are widely used in fine engineering fields such as electronic equipment. In this paper, the boiling heat transfer characteristics of refrigerants and nanofluids in microchannels are studied by applying electric fields, magnetic fields, and electromagnetic synergistic fields.
