First Claim
Patent Images
1. A fluid-cooled a.c. generator for use in a vehicle, comprising:
- a rotary shaft driven by an engine of the vehicle;
a rotor core fixed to said rotary shaft and adapted to be excited by an excitation coil;
a stator core surrounding said rotor disposed opposite an outer periphery of said rotor core and mounting a stator coil wound on said stator core;
a one piece thermoconductive fluid tube located within said generator and defining a cooling-fluid passage; and
a bracket member on which a tube trough is formed, and a bracket cover to close said tube trough;
wherein said one piece thermoconductive fluid tube is placed within said tube trough and in an internal space of said bracket member so as to house the tube therein.

Abstract
A liquid cooled a.c. generator whose cooling-fluid passage is formed with a thermoconductive tube in order to offer not only excellent watertight reliability but also greater cooling efficiency. In other words, a cooling-fluid passage for use in cooling any part to be liquid-cooled is formed with a good thermoconductive tube.
