The effect of inclination angle on the natural convection heat transfer from an inclined heated plate with rectangular grids is investigated. Experiments are performed in air for inclination angles in the range of -30 to +60 degrees measured from a vertical plane, for grid heights in the range of 5 to 10 mm, and for four values of the diagonal length of the grid. For each configuration, the surface heat flux ranges from 50 to 200 W/m^2. It is found that the rectangular grids enhance local heat transfer coefficients when these grids are applied to an inclined plate. The rectangular grids enhance the average heat transfer coefficients along the horizontal center line of the plate by up to 20 percent when compared to those coefficients for a smooth plate, even when the angles of inclination are ±30 degrees.
