Blast heat dissipation device with bidirectional air outlets

The utility model discloses a blast heat dissipation device with bidirectional air outlets. The blast heat dissipation device comprises a base and a blast fan, wherein the base comprises a pedestal; a wall is arranged above the pedestal and a space is defined; air outlets are respectively formed in the two symmetric sides of the wall; an airflow through hole is formed in the pedestal and arranged in the center of the space; air inlets are respectively formed in the two opposite sides below the pedestal; the blast fan is arranged at the position, corresponding to the central axis of the airflow through hole, of the space; the heat dissipation device is mounted on a radiator; when the draught fan is operated, the airflow is horizontally drawn by the air inlets, passes through each fin of the radiator, then enters into the space above the base through the airflow through hole, and is finally discharged from the air outlets at the two sides above the base.
