A theoretical analysis on heat pipe thermal performance using Deionized water or n-pentane as the working fluid has been carried out. Analysis on the maximum heat and capillary limitation is conducted for three microgroove cross sections: rectangular, triangular, and trapezoidal. The effect of microgroove height and width, effective length, trapezoidal microgroove inclination angle, and microgroove shape on heat pipe performance is analysed. Theoretical and experimental investigations of the heat pipes\u2019 heat transport limitations and thermal resistances are conducted.<\/jats:p>","DOI":"10.3390\/e20010044","type":"journal-article","created":{"date-parts":[[2018,1,11]],"date-time":"2018-01-11T13:36:15Z","timestamp":1515677775000},"page":"44","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Impact of Microgroove Shape on Flat Miniature Heat Pipe Efficiency"],"prefix":"10.3390","volume":"20","author":[{"given":"Fran\u00e7ois","family":"Ternet","sequence":"first","affiliation":[{"name":"Normandy University, Unicaen-LUSAC, 120 Rue de L\u2019exode, 50000 Saint L\u00f4, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hasna","family":"Louahlia-Gualous","sequence":"additional","affiliation":[{"name":"Normandy University, Unicaen-LUSAC, 120 Rue de L\u2019exode, 50000 Saint L\u00f4, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"St\u00e9phane","family":"Le Masson","sequence":"additional","affiliation":[{"name":"Orange Labs, 2 Avenue Pierre Marzin, 22307 Lannion, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,1,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.expthermflusci.2011.10.013","article-title":"Experimental study of slug flow for condensation in a single square microchannel","volume":"38","author":"Odaymet","year":"2012","journal-title":"Exp.
