The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 2.3 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.2 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00037 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.6 SJR: 0.433 SNIP: 0.593 CiteScore™:: 4.3 H-Index: 35

要約

For highly efficient solving of the power dissipation problem of electronic components with high heat flux, experimental study of the flow-jet combined boiling heat transfer on silicon chips was conducted. Micro-pin-fins with dimensions of 30×60 µm2 and 30×120 µm2 (thickness × height) were fabricated on the chip surfaces by the dry etching technique. The experiments were made at three different cross-flow velocities Vc (0.5,1.0, 1.5 m/s) and different jet velocities Vj (0-2 m/s) with two liquid subcooling ΔTsub (25° C and 35° C). A smooth surface was also tested for comparison. The micro-pin-fins showed a considerable heat transfer enhancement due to an increase in effective heat transfer surface area caused by micro-convection around micro-pin-fins. The maximum allowable heat flux qmax is increased and the wall superheat is decreased greatly. For a given Vc, the heat transfer enhancement is more significant as Vj increases, but the qmax increment decreases as Vc increases. The fin efficiency decreases as Vc or/and Vj increases or the heat flux q increases. The maximum qmax can reach 161 W/cm2 at Vc = 1.5 m/s, Vj = 2 m/s, ΔTsub = 35°C for chip PF30-120.
