SEALED HOUSING STRUCTURE OF MOTOR DRIVER

摘要

PROBLEM TO BE SOLVED: To enhance heat dissipation efficiency of a sealed housing structure for motor driver while sustaining its sealability without altering the external dimensions significantly. SOLUTION: A sealed housing structure 11 for motor driver comprises a sealed housing 12, and a metallic partitioner 14 dividing the inner space 13 vertically into two wherein outer air flows from one of vents 12e, 12f made in the left and right sidewalls of a housing 12 into a vent 14c made in the partitioner 14 and flows out from the other vent. Surface area in the housing can be increased while sustaining its sealability without altering the external shape of the housing significantly and heat dissipation efficiency of the housing can be enhanced significantly because air can be passed through.
