"Análisis comparativo del rendimiento térmico de colectores solares con adición de aletas y variación de altura en la placa absorbedora"

The following technological proposal deals with flat plate solar collectors that absorb solar radiation in the absorber plate and convert it into thermal energy that is transferred to the fluid that circulates through the collecting chamber, the applications are very wide, such as for heating homes or hospitals, wood drying, refrigeration systems, among the factors that affect improving the performance of the system is the increase in the total area of the collector plate through the adhesion of different geometric shapes, in this case rectangular, triangular fins , cylindrical, and height variation; the parameters of the fins were developed by calculating the effectiveness as the literature says; heat transfer by natural or free and forced convection (6m/s; 7m/s; 8m/s; 9m/s) was studied; where he managed to verify two important points that in the study of natural or free convection the best thermal performance was obtained with respect to the pattern; between the three types of fins; the cylindrical fins were where the highest thermal performance was obtained up to 46%; triangular fins up to 29% with radiation values of 280.3 W/m²; rectangular fins up to 26%; the height variation was the one with the least comparative thermal performance, obtaining up to 24% with radiation values of 380.1 W/m²; and the other important point that the higher the speed of the blower, the thermal performance of the different solar collectors decreases.
