Theoretical and experimental investigation of plate screen mesh heat pipe solar collector

A solar heat pipe collector was designed and fabricated to study its performance of the outdoor test condition. The thermal performance of the wickless heat pipe solar collector was investigated for pure water and nanofluid with varied range of CNT nanofluid concentration (0.15%, 0.45%, 0.60%, and 1% by volume) and various tilt angles (20 deg, 32 deg, 40 deg, 50 deg, and 60 deg). CNT nanoparticles with diameter 10–12 nm and 0.1–10 μm length are used in the present experimental investigation. The optimal value of CNT nanofluid concentration for better performance is obtained from the investigation. The thermal performance of the heat pipe solar collector with CNT nanofluid is compared to that of pure water.

Flat Plate Solar Collector

The objective of the present study is to investigate the performance of solar collector with serpentine shape of heat pipe and water-ethanol as a working fluid. Serpentine shape is easy of manufacturing and also to reduce cost of manufacturing. In this work, heat pipe is made from copper tube having ID 10mm and OD 12mm.The tube is bent in serpentine manner and filled with Water-ethanol as a working fluid with 70% filling ratio. The length of evaporator, adiabatic and condenser section was 480mm, 50mm and 65mm respectively. The test is conducted for coolant flow rate 4.5 kg/hr different angle of collector 20°, 31.5°, 40°, 50°, 60°. Result shows that water-ethanol collector gives better performance than collector with water as a working fluid. Maximum efficiency is observed at 31.5° inclination.
