HEAT RADIATOR

摘要

PROBLEM TO BE SOLVED: To provide a heat radiator for preventing only one radiation fin from being cooled by adjusting the flow of wind near the fin in the heat radiator for carrying out compulsory air cooling by a fan by allowing a plurality of radiation fins different in fin pitch to be opposed to each other. SOLUTION: Radiation fins 1 and 2 are formed by providing a plurality of projected fins 12 and 22 on bottom plates 11 and 21, respectively such that the fins are in parallel with each other. The radiation fins 12 and 13 are arranged to be opposed to each other by allowing the projected fins 12 and 22 to be opposed to each other. The radiation fins 1 and 2 arranged to be opposed to each other are different in the pitch of the projected fins 12 and 22. Radiation is carried out by allowing wind to circulate between the projected fins 12 and 22 arranged to be opposed to each other. A shielding plate 13 for adjusting the amount of circulating wind is provided on the radiation fin 1 whose pitch is broad. COPYRIGHT: (C)2006,JPO&NCIPI
