Abstract EN
In this work, a system of a heat pipe is implemented to improve the performance of flat plate solar collector.
The model is represented by square shape portion of the evaporator section of wicked heat pipe with a constant total length of 510 mm, and the evaporator section inclined by an angle of 30o.
In this models the evaporator, adiabatic and condenser lengths are 140mm, 140mm, and 230mm respectively.
The omitted energies from sunlight simulator are 200, 400, 600, 800 and 1000 W/m2 which is close to the normal solar energy in Iraq.
The working fluid for all models is water with fill charge ratio of 240% .
The efficiency of the solar collector is investigated with three values of condenser inlet water temperatures, namely (12, 16 and 20o C).
The numerical result showed an optimum volume flow rate of cooling water in condenser at which the efficiency of collector is a maximum.
This optimum agree well with the ASHRAE standard volume of flow rate for conventional tasting for flat plate solar collector.
When the radiation incident increases the thermal resistance of wicked heat pipe is decreases, where the heat transfer from the evaporator to condenser increases.
The numerical results showed the performance of solar collector with square shape evaporator greater than other types of evaporator as a ratio 15 In this work, a system of a heat pipe is implemented to improve the performance of flat plate solar collector.
