Abstract
The heat pipe solar water heater utilizes an evaporator to capture heat which is then used to heat water in the condenser section. The greater the heat that is able to be absorbed on the evaporator, can improve the overall performance of the solar water heater. Fins are added to the evaporator to increase the heat absorption area, but the shape of the fins can also affect the amount of heat absorbed. This research was conducted to determine the effect of fin shape on heat absorption in the evaporator section. Fins on the evaporator are made in a circular and flat shape with a width of 43 mm, a length of 516 mm for a flat fin and a diameter of 43 mm totaling 50 for a circular fin. From the test results it was found that the circular fin can reduce thermal resistance 43.48% greater than the flat fin and 9.89% of the solar water heater heat pipe without fins.
