| Abstract: |
| Objective To research the airflow decomposition method for large electronic racks. Methods With temperature difference and Nu as parameters for describing heat transfer performance, and based on the similar convection method, heat transfer performance in the decomposed fixture was made equivalent to the performance in the large rack before decomposition. Results After the airflow was decomposed, its cooling performance in the decomposed fixture was equivalent to the performance in the large rack. Conclusion The cooling airflow can be effectively decomposed by the method which can be applied to practical engineering. |
