▎ 摘  要

In the present study thermal performance of heat pipe were validated experimentally. Circular, auxiliary grooved heat pipe were charged with graphene nanofluid with different concentrations (0.6%, 0.75%), orientation, and flow rate are fixed as 90 degrees and 100 mL per minute. All the experimental results are validated and compared to base fluid (deionized water). From the experimental results, increasing nanofluid concentrations increases thermal performance and decreases thermal resistance. Although the wall temperature of heat pipe higher with graphene/water nanofluid than base fluid. Thus, graphene nanoparticles are suitable for heat pipe to increase their performance and capillary action.
