"24V DC Cooling Fan" is air-cooled radiator integral part of the cooling effect plays a vital role, is the only active radiator parts; at the same time, more work on the radiator has a decisive noise impact. "24V DC Cooling Fan" duties for the heat of: by virtue of their diversion effect, making the air to a certain speed, a certain way through the heat sink, the heat exchange between the air and the fins away deposited thereon heat, in order to achieve "24V DC Cooling Fan" "forced convection" cooling mode.
