And the direction in which the airflow enters the fan device 4 is also different from the air inlet direction D of the first embodiment (see FIG. 3), but flows through the heat absorbing member 443 from the outside in the radial direction of the heat absorbing member 443 and then through the air suction port. 414 enters the fan unit 4.

A third embodiment of the fan unit 4 is described below. Referring to FIG. 4, FIG. 7, and FIG. 9, each fan unit 4 includes a housing 41 and a blade 42. The first embodiment is different from the first embodiment. Implementation state The outer contour of the casing is rounded so that it can be easily placed into the first receiving pocket 2 of the heat sink (see Fig. 1), and the design of the suction opening 414 becomes a plurality of elongated strip-shaped openings. In addition, the fan device 4 of the embodiment may be externally connected to the air duct connector 43 or the cooling module 44 as shown in the first two embodiments, and only needs to be adjusted to match the embodiment. The housing 41 is sufficient.
