摘要:
A cooling system equipped with an advection-type fan is disclosed. The cooling system includes a casing (1, 3) and an advection-type fan (2, 4). The casing (1, 3) has a compartment (11, 31). The cooling system is characterized in that the compartment (11, 31) of the casing (1, 3) receives a heat-emitting source (111, 311) or a heat-conducting element (112). The casing (1, 3) further comprises at least one radial air-guiding opening (12, 32) communicating with the compartment (11, 31). The advection-type fan (2, 4) has a frame (21, 41) disposed in the compartment (11, 31). The frame (21, 41) has an air-guiding lateral wall (211, 411) defining a radial air channel (212, 412). The frame (21, 41) has a radial air inlet (213, 413) and a radial air outlet (214, 414), both the radial air inlet (213, 413) and the radial air outlet (214, 414) communicate with the radial air channel (212, 412). The radial air channel (212, 412) receives an impeller (22, 42) that causes air advection to dissipate the heat of the heat-emitting source (111, 311) or the heat-conducting element (112). The frame (21, 41) has two sides in an axial direction of the impeller (22, 42) that are completely laid open.

A fan module includes a housing (1, 1a, 1b, 1c, 1d, 1e, 5) and at leas one impeller. The housing (1, 1a, 1b, 1c, 1d, 1e, 5) includes first and second air channels (11, 51 and 12, 52). The housing (1, 1a, 1b, 1c, 1d, 1e, 5) further includes an axial air inlet (13, 53) in communication with the first air channel (11, 51) and a radial air inlet (14, 54) in communication with the second air channel (12, 52).

The at least one impeller (2, 2a, 2b, 2c, 2d, 2e, 3, 3a, 3b, 3c, 3d, 3e, 6) draws external air into the housing (1, 1a, 1b, 1c, 1d, 1e, 5) via the axial air inlet (13, 53) or the radial air inlet (14, 54) and expels air out of the housing (1, 1a, 1b, 1c, 1d, 1e, 5) via the at last one radial air outlet. By such an arrangement, external air can be guided into the fan module via different directions, providing enhanced cooling effect.
