Liquid cooling device

Abstract

A liquid cooling device includes an upper plate and a lower plate. The upper plate and the lower plate are combined together to define a chamber. A liquid working medium is accommodated within the chamber. The chamber includes a heat-absorbing section, a heat-radiating section and a driving section. The heat-absorbing section is in thermal contact with a heat generation element to absorb heat from a heat generation element. The heat is transferred to the liquid working medium, and a temperature of the liquid working medium is increased. The heat-radiating section is connected with a heat dissipation device. The heat is removed by the heat dissipation device, so that the temperature of the liquid working medium is decreased. The driving section is connected with a driving device. The liquid cooling medium with the decreased temperature is driven by the driving device and returned back to the heat-absorbing section.
