A device was developed to enhance heat transfer from heated horizontal plates. The device consists of six gutters with slits at the center for introduction of air, Heat transfer coefficients were measured by altering the device height above the heated surface. A height of about 10mm was found to give rise to higher heat transfer coefficients. The device augmented heat transfer rates by 1.2∼1.4 times in comparison with the heat transfer rates without the device.
