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

ABSTRAKT

In the presented study, a novel micro cooling system for electronic devices using a micro capillary groove evaporator was proposed. Based on experimental data in open (atmospheric) condition, we found that liquid level has an obvious influence on evaporating heat flux. For a given liquid level, there exists an optimum groove size, which maximizes evaporation heat transfer capacity. By using the optimum groove sizes in the open condition, two types of closed cooling systems for CPU chips for personal computers were designed: one was for desktop models and the other for notebook models. Their cooling performance to keep CPU chip temperature below 90 °C reached 3.35 × 105 W/m2 and 2.51 × 105 W/m2, respectively, for the desktop model by using ethanol and the notebook model by using methanol. Experimental results show that the maximum cooling capacities strongly depend on the condensation capacities of condensers in the closed cooling systems and volume fractions of working liquid in the evaporators.
