Patent ID: 7380584

Claim:
A pump-free water-cooling system, comprising: a heat-exchange circulating solution container in which heat-exchange circulating solution and vapor of the circulating solution are contained; a heat radiator provided on an outer wall of the container; a solution outlet for discharging from the container the heat-exchange circulating solution in the container; a gas-liquid two-phase fluid inlet for charging into the container gas-liquid two-phase fluid composed of the heat-exchange circulating solution at high temperature and vapor bubbles of the circulating solution; a first transportation route along which a sensible-heat-emitting heat exchanger is provided, the first transportation route linking with the solution outlet; a second transportation route along which heat exchange is carried out between heat-exchange circulating solution therein and the heat-exchange circulating solution in the container, or between the heat-exchange circulating solution therein, and the heat-exchange circulating solution in the container and the vapor of the heat-exchange circulating solution in the container; a third transportation route along which a heating heat exchanger is provided, the third transportation route linking with the gas-liquid two-phase fluid inlet; and a circulating-solution transporting route in which the first transportation route is linked to the second transportation route and the second transportation route is linked to the third transportation route.
