- Abstract:
- The thermal performanee of sinusoidal-eorrugated solar air colleetors was studied by numerieal sim.ulation by using CF software, and the parallel and vertieal models were analyzed. When the flow is parallelto the corrugated plate, the heat exchanger between the plate and the air is fully with less heat loss, and theheat eollecting efficieney is improved by 4. 1696 than the vertieal model; when the llow is vertieal to the corru.gated plate , the outlet temperature is relatively low with larger heat loss and low elficieney because of the deacspace. The thermal performanee in the U type, X type, S type of the sinusoidal-corrugated solar air collectorwas also analyzed. Results show that type X is the best of three types with the highest outlet temperature, theminimum heat loss and pressure drop, and the average thermal ellicieney of collector can reach 83.54%.
