Patent ID: 7766074

Claim:
A heat-dissipating device having an air-guiding structure, comprising: a heat-conducting seat; a fin assembly positioned above the heat-conducting seat and formed by arranging a plurality of heat-dissipating fins at intervals, an airflow path formed between each heat-dissipating fin for laterally flowing the air; a heat pipe having a portion to be heated and a heat-dissipating portion, the heat-dissipating portion of the heat pipe penetrating into each heat-dissipating fin and the portion of the heat pipe to be heated thermally connected to the heat-conducting seat; a fan assembly unit provided at one side of the fin assembly; and an air flow diverter having a top plate and straddling the fin assembly for locking the fan assembly unit onto the one side of the fin assembly, said top plate having two slots allowing top ends of the heat pipes to pass therethrough, wherein a space for lateral airflow is formed between the heat-conducting seat and the fin assembly, the other side of the fin assembly is provided with an air-guiding member, and the air-guiding member has a guiding space for laterally communicating with the space formed between the heat-conducting seat and the fin assembly; after the air blown by the fan assembly unit passes through the space formed between the heat-conducting seat and the fin assembly and is received by the air-guiding member, the air is guided to portions to the heat-dissipating portion of the heat pipe in a periphery of the heat-conducting seat via the air-guiding member.
