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

Evacuated Tubes, Solar Evacuated Tube - Apricus Solar

The heat produced by an evacuated tube can be extracted in a number of ways, depending on the design. The most common methods include direct water flow, U tube pipe, pipe-in-pipe or heat pipe. Apricus AP solar collectors use a heat pipe to extract the heat from within the evacuated tube and transfer it to heat exchanger part of the collector.

Thermal performance analysis of the glass evacuated tube

And in practical application of the glass evacuated tube solar collector with U-tube, the circular copper fin can not be tightly fitted inside the glass evacuated tube, so air is existing between the absorber tube and the copper fin due to the gap, which will also effect on the thermal efficiency of the solar collector.

Performance enhancement of filled-type solar collector

Mar 13, 2015 · In order to increase the efficiency of solar collector, a methodology is proposed based on the analysis of its influencing factors, such as thermal conductivity of filled layer, structure forms of filled layer and heat loss coefficient. The results of analysis show that the heat transfer between pipes in evacuated tube is one of the most important factors, which can lead to the decrease of the
