Title:
LIQUID COOLING STRUCTURE OF ROTATING ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/049831
Kind Code:
A1
Abstract:
Provided is a liquid cooling structure of a rotating electric machine, with which it is possible to prevent cooling efficiency from lowering even in a coil using a flat conducting wire. Guide block walls 12Ac are provided on both sides of a bobbin 12 in the width direction along the axial direction of a stator 10 so as to be each positioned between tooth portions 11b adjacent in the circumferential direction of the stator core 11 of the stator 10. Gaps are formed between coils 13 and the guide block walls 12Ac. Meanwhile, the guide block walls 12Ac are made adjacent to each other so as to close between the guide block walls 12Ac of adjacent bobbins 12.
