Heat pipes have immense potential in the future of thermal management in electronic devices. As a passive device, they rely solely upon capillary forces to recirculate the coolant from the condenser to the evaporator via a wicking structure. In intermediate temperature heat pipes the limiting factor for heat removal is the capillary limit, which indicates the maximum recirculation rate that the...

This paper presents the fabrication and application of a micro-scale hybrid wicking structure in a flat polymer-based heat pipe heat spreader, which improves the heat transfer performance under high adverse acceleration. The hybrid wicking structure which enhances evaporation and condensation heat transfer under adverse acceleration consists of 100 μm high, 200 μm wide square electroplated copp...

Thin-film evaporation in wick structures for cooling high-performance electronic devices is attractive because it harnesses the latent heat of vaporization and does not require external pumping. However, optimizing the wick structures to increase the dry-out heat flux is challenging due to the complexities in modeling the liquid-vapor interface and the flow through the wick structures. In this ...

Purpose An integral component in heat pipes (HPs) and vapor chambers (VCs) is a porous wicking structure. Traditional methods for manufacturing structures within HPs VCs involve secondary processes are generally limited to simple geometries. This work aims leverage the unprecedented level of design freedom laser powder bed fusion (LPBF) additive (AM) produce integrated VCs. Design/methodology/a...

Service providers have been frustrated with the lack in availability of specialised long-term supported accommodation for older people, particularly older homeless people, living with an acquired brain injury (ABI) and significant behaviours of unmet need. Although the incidence of ABI (particularly alcohol-related brain injury) is far wider than being confined to the homeless population, it is...

The crucial role of capillary pumping has motivated recent innovations in porous wicking materials for many energy and environment applications. Herein, the wick-based liquid propagation along with a surface, including both macroscopic water transport behavior microscopic dynamics, group nanostructured surfaces, is investigated. These hybrid surfaces are fabricated scalable way by bonding coppe...
