The thermal performance of finless heat exchangers is lower than that of louver fin heat exchangers under dry conditions.
“However, the thermal performance of finless heat exchangers is lower than that of louver fin heat exchangers under dry conditions.”
In finless heat exchangers, condensate can drop rapidly under the influence of gravity because there are no fins in the way.
“For finless heat exchangers, the condensate can drop rapidly under the influence of gravity because there are no fins in the way, as shown in Fig. 19 (b).”
Under wet conditions, the finless heat exchanger with LVG performs similarly to the louver fin heat exchanger in terms of thermal-hydraulic performance due to its excellent drainage performance.
“Under wet conditions, the finless heat exchanger with LVG performed similarly to the louver fin heat exchanger in terms of thermal-hydraulic performance due to its excellent drainage performance.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
