EXPERIMENTAL INVESTIGATION OF THE EFFECT OF USING PULSATING HEAT PIPES ON THE PERFORMANCE OF A SOLAR AIR HEATER
The performance of a solar air heater operating in conjunction with a pulsating heat pipe (PHP) is investigated experimentally in this study.This research focuses on the climatic conditions of the Semnan(35° 35 N, 53° 25 E) region in Iran.Pulsating heat pipes (PHP) are high-efficiency heat transfer devices, in which a combination of events and mechanisms occur and do not require any external force.The device fabricated for this study includes three main sections: flat collector, pulsating heat pipe and heat exchanger.The evaporator of the PHP is located inside the flat collector, while the condenser is inside the heat exchanger.The PHP is fabricated using a copper pipe with an internal diameter of 2 mm, and consists of 21 turns with charging ratio of 65％.the effects of local time is investigated for three month.Results show that while solar radiation increased, the performance of solar air heater increased too.
