Abstract

PURPOSE:To accomplish the improvement of cooling effect of the cooling fin for the subject rotary machine, especially when it is in high-speed operation, by a method wherein a plurality of vane plates are inserted alternately, heading to the direction of axis shaftline, into the discharge space along the circumferential direction. CONSTITUTION:In a plurality of disc-shaped fins 16, an air vent 20, having holes on the circumferential surface around a coil maintaining proper intervals, is formed on each fin 16, excluding the extreme outside two fins 16 and a radiation space 18 is formed between the adjoining two cooling fins 16. In the alternately provided radiation spaces of these radiation spaces 18, a vane plate 22 is provided almost at equal intervals heading toward the circumferential direction, each vane plate 22 has a vertical vane face on the disc-shaped fin 16 supporting the vane plates and these vane plates are provided in such a manner that they are heading toward the axial center of a heatpipe axle 12. As a result, the endothermic effect of the cooling heatpipe is greatly improved and an excellent cooling effect can be obtained.
