Special Issue Information

Dear Colleagues,

To date, more than 90% global energy consumption is related to thermal energy conversion, transportation, storage and management. Thermal materials play increasingly important roles in improving energy utilization efficiency, pursuing sustainable development of low-carbon human society, and ensuring a safe and stable operation of electronic devices as well. Recent years have witnessed a rapid development of nano-enhanced thermal functional materials. For example, various nanostructured solar absorbers have been compounded with thermal fluids or solid–liquid phase change materials to enable high-efficiency direct absorption-based solar–thermal energy harvesting, which in turn drives many solar–thermal processes such vapor/steam generation, seawater desalination, sterilization, domestic and industrial heating and electricity generation. The incorporation of functional nanofillers can not merely boost the thermal conductivity of polymeric packaging materials but also impart them with electromagnetic screening capabilities. In addition to single phase heat transfer, nanostructured fillers can also help enhance performances of liquid–gas phase change-based thermal management devices and systems.

This Special Issue of Nanomaterials aims to highlight recent research advances in developing advanced nano-enhanced thermal functional materials for a variety of heating/cooling related applications. We are looking forward to receiving contributions in the form of both research articles and review articles related to the synthesis, characterization, application of nano-enhanced thermal functional materials from diverse research disciplines to promote further rapid growth of the field.

Potential topics include, but are not limited to, the following:

  • Nanostructured thermal conversion materials: photo-thermal conversion materials, electro-thermal conversion materials, magnetic-to-thermal conversion materials;
  • Nano-enhanced thermal storage materials: solid sensible thermal storage materials, thermal nanofluids, solid–liquid phase change composites;
  • Nano-enhanced thermal management materials: nanostructured thermal fillers, thermal interface materials, high-thermal-conductivity nanocomposites, thermal insulation nanocomposites, radiative cooling materials;
  • Nano-enhanced thermal responsive materials: thermal actuation composites, thermal sensing and detection materials, infrared stealth composites;
  • Mechanistic understanding of nano-enhancement effect: modeling, simulation, theoretical prediction;
  • Diverse thermal-related applications: conversion and utilization of renewable thermal energy, personal thermal management, thermal management of electronic devices, advanced thermal-enabled material synthesis and fabrication techniques.

As electronic components progressively downsize and their power intensifies, thermal management has emerged as a paramount challenge. This study presents a novel, high-efficiency finned heat exchanger, termed Flat-Plate Oscillating Heat Pipe Finned Radiator (FOHPFR), which employs arrayed flat-plate oscillating heat pipes (OHP) as heat dissipation fins. Three-dimensional (3D)-printed techniques allow the internal microchannels of the FOHPFR to become rougher, providing excellent surface wettability and capillary forces, which in turn significantly improves the device’s ability to dissipate heat. In this study, the 3D-printed FOHPFR is compared with traditional solid finned radiators made of identical materials and designs. The impacts of filling ratio, inclination angle, and cold-end conditions on the heat transfer performance of the 3D-printed FOHPFR are investigated. It is demonstrated by the results that compared to solid finned radiators, the FOHPFR exhibits superior transient heat absorption and steady-state heat transfer capabilities. When the heating power is set at 140 W, a decrease in thermal resistance from 0.32 °C/W in the solid type to 0.11 °C/W is observed in the FOHPFR, marking a reduction of 65.6%. Similarly, a drop in the average temperature of the heat source from 160 °C in the solid version to 125 °C, a decrease of 21.8%, is noted. An optimal filling ratio of 50% was identified for the vertical 3D-printed FOHPFR, with the minimal thermal resistance achieving 0.11 °C/W. Moreover, the thermal resistance of the 3D-printed FOHPFR is effectively reduced compared to that of the solid finned radiator at all inclination angles. This indicates that the FOHPFR possessed notable adaptability to various working angles. Full article
