Claims

[Claims for Utility Model Registration] A large number of flat ducts for passing cold air are arranged in a case at predetermined intervals along the lateral direction, and a partition plate allows the inside of the case to extend along the length of the flat ducts. A heat exchanger with a structure divided into three chambers along the direction is attached to the upper part of the motor body, and air heated by the motor circulates through the gap between adjacent flat ducts and inside the case and the motor body. A heat exchange type cooling device configured to cool a variable speed motor by exchanging heat with cold air flowing in a flat duct and discharging the cold air as hot air. 1. A heat exchange type cooling device for a variable speed motor, characterized in that a cold air blowing fan is attached to the heat exchanger to be driven and rotated by a motor to forcibly send cold air into the flat duct.
