A numerical study of free convection cooling of electronic equipment
Abstract
A numerical analysis of free convection from electronic components on PWB placed horizontally in the cabinets is described. The effects of aspect ratio H/L (H is the height of cabinet, L is length of it), dimensionless heat conductance of cabinet walls and baffle plate located at open side of cabinets on the free convection heat transfer in the cabinets were numerically investigated using finite difference method. It was clarified that the overall heat transfer coefficient was about 20% lower than that of an upward facing heated plate placed horizontally in semi-infinite space, and the streamline patterns obtained by present numerical analysis were in good agreement with the flow patterns visualized in the previous experiments.
