ABSTRACT:
A cooling device includes a liquid chamber having a liquid inlet and a liquid outlet. A bent pipe includes a straight tubular heat pipe component provided extending from the inside to the outside of the liquid chamber. A spiral heat pipe component communicating with the straight tubular heat pipe component and extending to surround the same spirally is provided. In an internal space where the spiral heat pipe component and the straight tubular heat pipe component communicate with each other, a working fluid serving as a heat carrier is sealed. An ultrasonic motor for rotating integrally the straight tubular heat pipe component and the spiral heat pipe component is provided. A radiating fin structure is provided on the straight tubular heat pipe component positioned outside the liquid chamber. As a result, it is possible to make the device lighter, smaller and more reliable without decreasing the cooling performance as compared to conventional cooling devices.
