Heat pipes for passive solar heating systems

Abstract

In the presented research work, heat pipes of gravitational and ring type were investigated. Two types of heat pipes were fabricated and tested under natural conditions for the study. According to the results of experiments, depending on the materials and dimensions of the heat pipes under study, the average value of the temperature difference in the gravitational heat pipe is 1.7 times higher, and the thermal resistance is 1.3 times lower.
