Liquid cooling system

Abstract

A liquid cooling system includes a heat-absorbing unit, a heat-dissipating unit, at least one pipe, a coolant and a magnetic field generator for generating a magnetic field. The pipe interconnects the heat-absorbing unit and the heat-dissipating unit, thereby the heat-absorbing unit, the heat-dissipating unit and the pipe cooperatively form a circulatory channel. The coolant is received in the circulatory channel, the coolant comprises a liquid and a plurality of magnetic particles dispersed in the liquid. At least one of the heat-absorbing unit and the heat-dissipating unit is located in the magnetic field. The liquid cooling system increases the thermal conductivity of the coolant by making the coolant flow turbulently. The efficiency of the liquid cooling system resultantly being increased.
