To provide a lightweight and compact device that can efficiently cool an inverter for controlling an in-wheel motor.SOLUTION: A cooling device of an in-wheel motor comprises: an inverter case 17 in an airtight structure for storing an inverter 19, which is provided inside a wheel 1 together with a motor 5; a cooling medium 23 with electrical insulation enclosed in the inverter case 17, which is evaporated by receiving heat from the inverter 19 so that at least a portion of the inverter 19 is immersed therein; a heat radiator 18 that radiates heat from steam of the cooling medium 23 to condense the vapor; a steam tubing 24 through which the inverter case 17 is communicated with the heat radiator 18 so that the steam of the cooling medium 23 is flown from the inside of the inverter case 17 to the heat radiator 18; and a liquid return pipe conduit 25 through which the heat radiator 18 is communicated with the inverter case 17 so that the cooling medium 23 condensed by the heat radiator 18 is refluxed from the heat radiator 18 to the inverter case 17.SELECTED DRAWING: Figure 2

    【課題】インホイールモータを制御するインバータを効率よく冷却できる軽量・コンパクトな装置を提供する。【解決手段】インバータ19を収容しかつホイール1の内側にモータ5と共に設けられた気密構造のインバータケース17と、インバータ19の少なくとも一部を浸漬させた量でかつ前記インバータ19から熱を受けて蒸発するインバータケース17に封入された電気絶縁性の冷却媒体23と、冷却媒体23の蒸気から放熱させて蒸気を凝縮させる放熱器18と、冷却媒体23の蒸気をインバータケース17の内部から放熱器18に流動させるようにインバータケース17と放熱器18とを連通させている蒸気管路24と、放熱器18で凝縮した冷却媒体23を放熱器18からインバータケース17に還流させるように放熱器18とインバータケース17とを連通させている液戻り管路25とを備えている。【選択図】図2
