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.
Claims9
A heat-dissipating module, comprising:
- a first fan unit located on an air inlet side, said first fan unit including a casing having a plurality of side walls and an impeller received in said casing of said first fan unit, said side walls of the first fan unit integrally forming at least one engaging groove;
- and
- a second fan unit located on an air outlet side, said second fan unit including a casing having a plurality of side walls and an impeller received in said casing of said second fan unit, said side walls of the second fan unit integrally forming at least one engaging lug to engage with said engaging groove;
- 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 at least one of said side walls of said casing of said first fan unit and at least one of said side walls 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 of the side walls of the first fan unit and said engaging lug of the side walls of the second fan unit.
