Title:
液冷装置及び液冷装置を備えた回転電機
Document Type and Number:
Japanese Patent JP7433078
Kind Code:
B2
Abstract:
To easily fit two members composed of a nipple and a water channel portion by improving fixing force even when a temperature is increased or decreased compared to that at the time of fitting.SOLUTION: A liquid cooling device includes a water channel connection portion 11 disposed on a water channel portion 1 and connecting a water channel and the outside, and a press-fitting portion 100 disposed on the water channel connection portion 11 to press-fit a nipple 3. A thermal setting portion 110 is disposed on the water channel connection portion 11, the nipple 3, and a fixing member 2 and the water channel portion 1 are successively disposed from a press-fitting central axis of the nipple 3 toward a radial direction on the thermal fixing portion 110. A thermal expansion coefficient of the nipple 3 is smaller than a thermal expansion coefficient of the water channel portion 1, and a thermal expansion coefficient of the fixing member 2 is larger than the thermal expansion coefficient of the water channel portion 1.SELECTED DRAWING: Figure 2
