Again or as shown in Figure 2, the radiating fin 20a of circle distribution is the center with central cylindrical heat conductor 21a, the fan 22a that arranges in pairs or groups scatters and reaches whole heat sinking function to circumference.
But, above-mentioned known heating radiator, the fan of all need arranging in pairs or groups dispels the heat, and can reach certain radiating effect, however the setting of fan except taking more space, also can cause the increase of cost.
Moreover, heating radiator with this moulding, the efficient of heat radiation is connected to an enclosed planar because of radiating fin with respect to the fan another side, and the heat-sinking capability in the finite space can't concentrate heat radiation, especially, known open radiating fin, the heat that produces of discharging because of open radiating fin is a solid matter, is conducted heat with heat exchange pattern, the heat of generation when speed is much slower than the thermal convection circulation institute central microprocessor that discharge and operates is so its radiating efficiency is not good.
So as from the foregoing, above-mentioned known heating radiator on reality is used, obviously has inconvenience and exists with defective, and wait to be improved.
