Water-cooling heat dissipation system

Abstract

A water-cooling heat dissipation system for dissipating a heat-generating device includes a water pump, a water-cooling apparatus, and a cooling apparatus. The water pump is configured for transferring coolant via a first pipe. The water-cooling apparatus is capable of mounted on the heat-generating device and receiving the coolant from the water pump via the first pipe to cool the heat-generating device, and then outputting heat absorbed coolant heated the heat from the heat-generating device. The cooling apparatus is configured for receiving the heat absorbed coolant from the water-cooling apparatus via a second pipe, and removing heat from the heat absorbed coolant, and then transferring the coolant to the water pump via a third pipe.
