PURPOSE:To form rapid current of cooling fluid even in the rear current of a boss, and to hold a high heat transfer rate by a method wherein guide vanes are provided on the plate of an auxiliary fin. CONSTITUTION:A flat element is placed between both the side fins, and generated heat in the element passes the boss of the main fin 3 and is transferred from the plate of the auxiliary fin 4 to the circumferential fluid. When the guide vanes 5 are provided on the fin plate, a dead water region is not generated in the rear of the boss, average heat transfer rate is enhanced, and cooling capacity of the fin can be enlarged remarkably. |
