BUSTOS BARRAGAN, Joaquín Mateo. Performance of a solar concentrator and influence of the tube’s hydrodinamic height on the termosiphon effect. Perfiles [online]. 2024, vol.1, n.31, pp.16-26. ISSN 2477-9105.  https://doi.org/10.47187/perf.v1i31.254.

The aim of the article was to investigate the impact of vacuum tube joints on the thermosiphon effect. The effect of the tube connections in the solar heater was analyzed using two different height arrangements. These configurations were simulated under the same conditions through software that allowed us to enter data related to the city of Riobamba, which has a low latitude. The first design was made by inserting the vacuum tubes in the middle of the tank, while the second was placed at the bottom of the tank. For the thermal-optical analysis, a solar reflector was used, and the data obtained during the simulation was manipulated. A greater temperature distribution was found in the tank for higher hydrodynamic heights. Acceptable values ​​of useful heat and heat losses were determined. The position of the joints directly influenced the thermosiphon effect since it increased the force with which the water circulated in the tank due to the greater volume of water in this configuration. The heat losses evidenced the need to use another type of cover. However, this model generated enough energy to be used domestically
