(1) understand the "Waterproof Cooling Fan" curtain of paper thickness, and now the market is only 10 centimeters curtain paper with 15 cm thickness. So why the cooling effect of the thickness of 15 cm to 10 cm than good? In fact, it plainly is very simple, such as a red-hot iron bar, drop by a half a meter thick pool temperature is certainly no more than the pool by one meter thick decline, the; because iron bars in a meter deep pool longer in time reasons. By the same token hot air through the 10 cm thick curtain of paper longer than 15 cm thick curtain through the paper to be less, so the cooling effect is more than 15 centimeters lower paper curtain. If you want to increase the "Waterproof Cooling Fan" cooling effect can be replaced 15 cm thick.
(2) for a corrugated wave height and the inclination of the air curtain in the flow path will also be finalized, the air flow boundary condition is also to be determined. At this time, the air flow pattern "Waterproof Cooling Fan" depends on the air flow inside.
