US 2020/0029466 A1 · LIQUID-HEAT-TRANSMISSION DEVICE

Abstract

A liquid-heat-transmission device includes a vapor chamber, a cover, and a channel structure. The cover covers on a surface of the vapor chamber and a flow chamber is defined thereby. A water inlet and a water outlet respectively communicated with the flow chamber are defined on the cover. The channel structure is arranged in the flow chamber. The flow channel structure includes multiple fins arranged between the water inlet and the water outlet and with an interval apart. Each fin is extended in a longitudinal direction on a surface of the vapor chamber and connected to the vapor chamber and the cover. The vapor chamber is attached to a heat source, and a working fluid flows through the flow chamber from the water inlet of the cover and is drained after fully exchanging heat with the vapor chamber.
