Abstract

PURPOSE:To improve cooling efficiency and simplify the constitution by utilizing a frame commonly as cooling fin for the negative rectifier group and installing a cooling fin for the positive rectifier group on the outside of said frame through the intermediary of insulation material. CONSTITUTION:A cooling fin 31 for the negative rectifier group constituting an all-wave rectification device 3 is substituted by a frame constituting bracket for a bearing 23. Outside of joint-use frame for the negative cooling fin, the cooling fin 31 for the positive rectifier group is screwd down with a bolt 5. In addition, a cover 6 is attached in such manner as to protect the positive cooling fin 31. In this way, it is possible to increase the cooling area for improvement of cooling efficiency and make an easy assembly or disassembly operation.
