Abstract
A heat-dissipating module includes a first fan unit and a second fan unit, which are serially connected together to provide an air inlet and an air outlet. Each of the first fan unit and the second fan unit includes a casing and an impeller. At least one side air inlet is defined in at least one of a plurality of sides of the casing of the first fan unit and a plurality of sides of the casing of the second fan unit. The air inlet amount and the air outlet amount of the second fan unit are increased by the side air inlet. The air density distribution is uniform, and the wind noise during operation is lowered.

A heat-dissipating module, comprising:
- a first fan unit located on an air inlet side, said first fan unit including a casing having at least one side wall and an impeller received in said casing of said first fan unit, said side wall of the first fan unit integrally forming at least one engaging groove or at least one engaging lug;
- and
- a second fan unit located on an air outlet side, said second fan unit including a casing having at least one side wall and an impeller received in said casing of said second fan unit, said side wall of the second fan unit integrally forming at least one engaging lug or at least one engaging groove to engage with said engaging groove or said engaging lug of said first fan unit;
- said first fan unit and said second fan unit being serially connected by engaging said engaging lug with said engaging groove, at least one side air inlet being integrally formed in said side wall of said casing of said first fan unit or said side wall of said casing of said second fan unit for increasing an air inlet amount and an air outlet amount of said second fan unit, said side air inlet being located at a position adjacent to one of said engaging groove or said engaging lug of said first fan unit and said engaging lug or said engaging groove of said second fan unit.
A heat-dissipating module, comprising:
- a first fan unit located on an air inlet side, said first fan unit including a casing having at least one side wall and an impeller received in said casing of said first fan unit;
- and
- a second fan unit located on an air outlet side, said second fan unit including a casing having at least one side wall and an impeller received in said casing of said second fan unit;
- said first fan unit and said second fan unit being serially connected, at least one side air inlet being integrally formed in said side wall of said casing of said first fan unit or said side wall of said casing of said second fan unit for increasing an air inlet amount and an air outlet amount of said second fan unit, said side air inlet being located at a position adjacent to a boundary line between said side wall of said first fan unit and said side wall of said second fan unit.
