Abstract
The heat transfer analysis and temperature distribution inside printed circuit
board (PCB) enclosures for different geometries was investigated in this paper.
Herein, the computational fluid dynamic (CFD) solver caffa3d.MB was
employed to simulate the 3D incompressible Navier-Stokes equations. The
numerical method uses a spatial discretization based on block-structured, nonorthogonal
body fitted grids. Numerical simulations for two different PCB
geometry configurations are analysed using eight Reynolds numbers. The
temperature field is practically the same above the plate encasing the PCB,
differences appear below the plate. While analysing the plane just below for the
open geometry the main consideration is the presence of a hot zone. The greater
heat transfer is obtained in the top channel for both geometries. In turn, in the
bottom channel the heat transfer is greater in the closed geometry than the open
one. The calculating results show that the cooling of the PCB is more efficient
for the closed geometry.
