Heat-Dissipation Performance of Nanocomposite Phase-Change Materials in a Twin-Heat-Source System
Round 1
Reviewer 1 Report
This paper investigates a two-heat source system with the CuO/paraffin nanocomposite phase change materials. Heat transfer characteristics of the heat pipe-PCMs module is performed. The effects of fan power and heating power on the cooling module performance is studied. The results of this work is reasonable and vivid, so generally speaking, this work has the instructional value of the energy storage application, and it is recommended to be published after minor revision.
- The title of this paper is the “…..in a Multi-Heat Source System”. However, in the text, two heat sources is used, so it is not exact to say “a Multi-Heat Source System” in the title. It is recommended to be revised as “a Two-Heat Source System”.
- The “Introduction” should present the state-of-art of phase change materials as well as the research drawback. Besides, the problem this paper is aimed at to solve should be stated clearly, and the innovation should be highlighted.
- The mathematic principles this work follows has not be given, so it is recommended to add the fundamental principles of this study.
- To present more comprehensive background on this field, the following literature is recommended for authors to be compared and referenced in the literature review:

Reviewer 2 Report
The authors studied the heat transfer characteristics of the CuO/paraffin nanocomposite phase change materials. The work, of course, has a practical and scientific interest. However, the following issues should be addressed before the publication:
- Figure 1(b) would be good to replace with the scheme for composite preparation, for example.
- In the Experimental preparation section, I strongly encourage the authors to avoid using a table and preciously describe the procedure of the preparation and characterization of the composite material, because it is not clear now. The preparation section should be revised with more details (e.g. temperature control was provided or not, the condition of drying the material, etc.)
- “Experimental Uncertainty Analysis” what is the reason to put this section in the scientific article, what special interest in formula 1 to put this formula in the main text of the manuscript?
- Authors used “physical images” or “physical photos”. The term “physical” has some special sense here?
- In the capture to Figure 2. What does “(mm)” mean. The units should be provided to the image in the required place.
- Line 16. The authors should clarify the meaning of “10 W-10 W” in the abstract before using it.
- Line 25. If the authors mean the undercooling, they should use “supercooling” in place of “super cooling”.
