<p>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 housing (1, 1a, 1b, 1c, 1d, 1e, 5) further includes at least one radial air outlet (15, 55) in communication with the first and second air channels (11, 51 and 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.</p> |
