Title:
WINDING UNIT
Document Type and Number:
Japanese Patent JP2019160925
Kind Code:
A
Abstract:
To provide a winding unit that improves heat dissipation efficiency of a winding part while suppressing heat generation of a case or the like based on a leakage magnetic flux of the winding part.SOLUTION: A winding unit 1 includes: a winding part 2; a case 3 that houses the winding part 2; a filling resin 4 filled in the case 3 and sealing the winding part 2; and a heat dissipating unit 5 made of a material having a higher thermal conductivity than the filling resin 4 and extending from an inner surface 23 of the case 3 toward the winding part 2 on an outer peripheral side of the winding part 2. At least a distal end portion 31 in an extending direction of the heat dissipating unit 5 is formed in a plate shape extending in a radial direction and an axial direction of the winding part 2.SELECTED DRAWING: Figure 1
