Abstract

PURPOSE: To economize a material and raise a cooling effect, by using a fan-shaped core as both its side faces are exposed and by stratifying sheets with one another so that comb-like projections are located on both the ends of the sheets.
CONSTITUTION: The internal and lateral faces of the fan-shaped core 9 are exposed as they are. Core bolts 10 are engated in round slots 5 of the fan-shaped core 3 to hold it. The core bolts 10 are fixed in prescribed positions inside a frame 11. A ventilation passage 12 is defined between the fan-shaped core 3 and the frame 11. The half parts of the sheets are alternately stratified with one another to make the fan-shaped core 3. The comb-like projections are provided on the inside of the core. This results in economizing the material, increasing the surface area of the core and raising the cooling effect.
