"220V AC Cooling Fan" system cooling mode selection should take full account of the many factors that system heat power, temperature / volume / weight requirements, protection, cooling equipment operability, price, and ultimately select the most suitable products, effective heat dissipation. "220V AC Cooling Fan" cooling are divided into: natural cooling, forced air cooling. Liquid cooling. Now widely used in cooling mode is still cooling. The following table reflects the relationship between heat flux and temperature conditions under different cooling methods. "220V AC Cooling Fan" Natural Cooling: air natural convection heat to the surrounding space. This cooling method can not use the heating power, weight, temperature and other demanding applications. Advantages: simple structure, no noise, low prices.
