Abstract

Turbulent impinging slot jets at three different angles and four different impingement spaces were analyzed numaberically using the SIMPLE alogrithm and an RNG-based k - epsilon turbulence model to investigate the flow field structure and heat transfer characteristics. Under a certain condition, the heat board of a device is cooled by impinging jet, designed three Different jet angles, including 35ø,45øand 55ø, The results show that as the angle becomes large, the air convection in the low temperature region becomes stronger, and the heat exchange rate is larger in the high air domain. Namely, when the oblique impingement angle increases, the convective heat transfer in the air field at both sides of the low temperature zone and the high temperature zone is more severe, which is not conducive to the cooling of the core area. Four different partition schemes were designed to form different impinging jet space, the results show that in a certain range, the larger the jet space, the air field will have a larger vortex, which will reduce the cooling efficiency.
