Abstract

The availability of fossil energy sources is rapidly decreasing because it is one of the main energy source therefore alternative energy is a need as a substitute for fossil energy, one of which is solar energy. Solar energy is used as a heater or dryer, in this case, a solar water collector. Solar air collector is one of the heat exchangers that converts solar energy into heat energy. The performance of the solar air heater collector can be improved in several ways, including changing the shape of flat plate absorber to v-corrugated with an inline dimple to expand the absorption area and heat transfer on the absorber plate. Some researchers reported that v-corrugated absorber plates provide better heat transfer than flat plates and others also concluded that the addition of dimple can increase the heat transfer area in an air heater solar collector compared to a flat plate. The dimple diameters used are 5 mm; 7 mm; and 9 mm; towards the direction of the flow of working fluid under the absorbent plate with the air mass rate is 0.001 kg/s, 0.002 kg/s, 0.004 kg/s and 0.006 kg/s and the radiation intensity of 431 W/m2, 575 W/m2 and 719 W/m2. The experimental results show that the 9mm dimple with a mass flow rate of 0.006 kg/s and radiation intensity of 719 W/m2 produced the greatest heat output (Quse) of 51.59 Watt. The greatest efficiency on the v-corrugated absorber plate with dimple diameter of 9 mm at a mass flow rate of 0.006 kg/s with a radiation intensity of 431 W/m2 is 0.48.
