As the surface roughness increases, the heat transfer coefficient (HTC) also enhances owing to the increased number of bubble nucleation sites [21; 22; 23; 24]. Highly wetted surfaces exhibit lower HTCs at low heat-flux intervals because they require more thermal energy to activate bubble nucleation. Conversely, surfaces with lower wettability show higher HTCs at low heat-flux intervals because they allow for early bubble nucleation and more nucleation sites [25; 26; 27; 28]. The relationship between HTC and CHF has been established such that a surface with low wettability achieves an increased HTC at the expense of a decreased CHF. In contrast, a surface with high wettability achieves an increased CHF at the expense of a decreased HTC [29; 30; 31]. Owing to the development of two-phase immersion cooling, boiling with highly wetted liquids has been extensively studied in recent years. To improve the boiling heat transfer of a highly wetted liquid, surface modification methods, such as ultrafast laser texturing [32; 33; 34] and chemical coating [28; 35], have been widely used. [PERSON] et al. [32] conducted pool boiling experiments using water and FC-72 on laser-textured surfaces. The laser-textured surfaces offered multi-scale microcavities to facilitate nucleation. [PERSON] et al. [33] conducted pool boiling experiments using water and FC-72 as working fluids on surfaces produced using selective laser melting. They found that the fin separation of micro-fin surfaces had a significant impact on the HTC. Their results indicated that the optimal fin separation for micro-fin surfaces was 300 \(\upmu\)m. [PERSON] et al. [28] conducted pool boiling tests on graphene and fluorinated-graphene-coated surfaces, using R-141b as a working fluid. The superior heat transfer performance of the F-graphene-coated surface was attributed to its highest contact angle among the test surfaces, which led to a greater number of nucleation sites. To further enhance BHTC, the use of a biphilic surface as a boiling surface is beneficial because it exploits the advantages of high and low wettabilities. Inspired by biphilic surfaces [36; 37; 38], surfaces with anisotropic wettability also exhibit distinct wettability characteristics [39; 40; 41; 42; 43]. [PERSON] et al. [40] used a laser belt-processing method to create microgrooves on an Inconel 718 surface. The contact angle measured in the direction parallel to the groove was different from that measured in the normal direction. This phenomenon was attributed to variations in the energy barriers between the two directions.
