Abstract
The utility model provides a built-in combined type heat sink, which comprises a radiator plate series and a fan (4). The series of radiator plates consists of a plurality of radiator plates (1) vertically arranged on a heat-radiating substrate (2) in parallel. The utility model is characterized in that two series of radiator plates (1) on the heat-radiating substrate (2) are provided, which are arranged respectively at the two ends of the heat-radiating substrate (2); a blowing zone (3) is formed between the two series of radiator plates (1); the fan (4) is a centrifugal fan arranged in the blowing zone (3) of the channel flow. The utility model changes the prior piling up arrangement of the fan and the radiator plate series into prior embedding arrangement, and discharges the air drawn by the beam-barrel to the two lateral sides of the channel flow by the centrifugal fan. Compared with prior heat-radiating structure, the type of heat-radiating structure greatly reduces the height of heat-radiating structure, makes the structure more compact, reduces heat-radiating material, and reduces the weight of the heat-radiating structure. Since the blowing direction of the fan is in parallel with the channel flow, the wind resistance of the fan is low and the fan blows air directly to the root of the radiator plates, with good heat-radiating effect.
