PROBLEM TO BE SOLVED: To achieve size reduction and manufacturing-cost reduction of a heat sink, while enhancing heat-dissipation performance by making the air flow smooth. SOLUTION: The heat sink 1 is provided with a heat-receiving plate 2 mountable to a heat source, heat dissipating sections 3, 21 provided on the heat-receiving plate 2, and a cooling fan 4 provided so as to be capable of sending cooling air to the heat dissipating sections 3, 21. The heat dissipators 3, 21 are respectively provided with heat transfer plates 5, 22 erected on the heat-receiving plate 2, at a prescribed interval and heat-dissipating fins 6, 24 vertically interposed between the respective heat transfer plates 5, 22. Spaces 7 for sucking/exhausting the cooling air are formed between the lower end of the heat-dissipating fin 6 and the heat-receiving plate 2. Similarly, spaces 27 for sucking/exhausting the cooling air are formed between the lower end 26 of the heat-dissipating fin 24 and the heat-receiving plate 2. COPYRIGHT: (C)2007,JPO&INPIT
