Abstract

A heat dissipating device has a thermal board, at least one cooling fin, and a working fluid. The thermal board has at least one chamber and a passive one-way valve section. Each of the at least one chamber has a first inlet and at least one first outlet. Each of the at least one cooling fin has an inner space, at least one second inlet, and a second outlet. The second inlet is connected to the first outlet. The second outlet is connected to the first inlet. The working fluid is filled in the chamber and the inner space. The passive one-way valve section is configured to limit the working fluid to cycle in the chamber and the inner space along a single direction. The heat dissipating device facilitates the cycling capability of two phases flow coolant and provides a heat dissipating capability.
