220V AC Cooling Fan convective heat transfer law domination

Factors that affected by heat convection heat transfer law governed, and governed by the laws of fluid flow, heat transfer process is a kind of complex, convective heat transfer performance in "220V AC Cooling Fan" more.
1. "220V AC Cooling Fan" for different reasons generated by fluid flow can be divided into natural and forced convection.
2. Press the flow properties to distinguish, there's not laminar and turbulent. "220V AC Cooling Fan" fluid transition from laminar to turbulent flow due to the loss of stability of the results. Generally Reynolds number (Re) of size, as laminar or turbulent judgment basis.
3. Effect on convective heat transfer fluid properties. For example, viscosity, density, thermal conductivity, specific heat, thermal diffusivity, and so on, they differ with the fluid, with the temperature changes, thus changing the convective heat transfer effect.
4. "220V AC Cooling Fan" geometry influence on the heat transfer surface convective heat transfer.
