| Abstract: | The temperature and flow fields of CPU heat sink Cooled by vertical jet are investigated based on numerical method. Furthermore, the recirculating flow is found under the low part of the fin, and it would deteriorate the heat dissipation at a certain degree. The heat dissipation performance of CPU heat sink cooled by vertical uniform jet is analyzed by numerical simulation under different conditions. These results are useful for the design of the heat sink with efficient performance and the further research. |
