Evacuated Tube Solar Collector - an overview

Evacuated tube solar collectors operate different from the collectors presented so far as they usually consist of a heat pipe inside a vacuum-sealed tube. The area of one tube is small; therefore to increase the heat collection area many tubes are connected to the same manifold as shown in Fig. 4.13 (usually 10–20 tubes are used). The evacuated tube collector (ETC) usually employs a fin with
