Abstract: We constructed a 3D steadystatus model for flat microheat pipe arrays solar energy air collector. We also performed grid segmentation and numerical calculation for the physical model of single heat collection unit with software Gambit and Fluent. We further simulated heat exchange and flow of single pipe and verified its effectiveness by experiments.Experimental results show that the simulated results fit well with the experimental results, less than 12% deviation.This demonstrates the rationality of the model. Our research can provide theoretical basis for optimization design of flat microheat pipe arrays solar energy air collector in future.
