Liquid cooling device

Abstract

A liquid cooling device includes a liquid block, a heat-dissipating plate, a thermal-conductive pipe, a pump and a heat sink. The liquid block, the pump, and the heat sink are connected by ducts. The pump drives a coolant to circulate among them. The thermal-conductive pipe is mounted on the heat-dissipating plate. Both ends of the thermal-conductive pipe are connected to the liquid block for the coolant to flow through. The liquid block and the heat sink are respectively mounted on the corresponding electronic devices to absorb heat using the circulating coolant. The heat sink is used to dissipate heat from another heat-generating electronic device. Therefore, one less liquid block is required, and the production cost becomes lower.
