... prototype of Koukoravas et al. [ 20 ]. This system facilitates a phase-change closed chamber, with a wick evaporator opposing a wettability-patterned [ 21 ] condenser. This type of biphilic patterning [ 22 ] has been shown to improve the condensation heat transfer coefficient [ 23 ]. The wick-free condenser...

...Houxue Huang; Navid Borhani; John Richard Thome Multi-microchannel evaporators with flow boiling, used for cooling high heat flux devices, usually experience transient heat loads in practical applications. These transient processes may cause failure of devices due to a thermal excursion or poor...

... immersion cooling with fluorocarbons have shown the effectiveness of boiling enhancement structures in lowering boiling incipience, raising the critical heat flux, and reducing evaporator size. Two-phase thermosyphons are an alternative to liquid immersion cooling, where phase change liquid cooling can...

... a temperature range from 15 ° C to 100 ° C . The locations of the thermocouples monitored in the test are shown in Fig. 2 . The base temperature of the evaporator T base was measured with an embedded T-type thermocouple. The thermocouple was fitted into a 0.38 mm wide...

...Johnathan S. Coursey; Jungho Kim; Paul J. Boudreaux This paper presents the results of an investigation of the thermal performance of a graphite foam thermosyphon evaporator and discusses the foam’s potential for use in the thermal management of electronics. The graphitized carbon foam used...

...Y. H. Yan; J. M. Ochterbeck A cylindrical capillary pumped loop evaporator operating under steady-state conditions was studied using a two-dimensional numerical model. Parameters affecting the phase conditions in the wick structure and thermal-fluid behavior in the evaporator liquid core were...
