Liquid cooling device

Abstract

A liquid cooling device includes a heat dissipating module and a container thermally connected to the heat dissipating module. The heat dissipating module includes a chamber, a first liquid inlet accessing the chamber and a first liquid outlet accessing the chamber. The container includes a liquid feeding channel and a liquid releasing channel isolated from each other. The liquid feeding channel accesses the chamber via the first liquid inlet. The liquid releasing channel accesses the chamber via the first liquid outlet. Heat absorbed by the heat dissipating module is taken away by a coolant successively flowing through the liquid feeding channel, the first liquid inlet, the chamber, the first liquid outlet and the liquid releasing channel.
