Heat dissipation system

Abstract

An exemplary heat dissipation system includes a built-in heat dissipation module for being positioned in a computer case, a liquid pump communicating with the built-in heat dissipation module, and an add-on heat dissipation module for being positioned outside of the computer case. The built-in heat dissipation module includes cooling fluid. The add-on heat dissipation module includes a receiving frame and a heat dissipation device fixed to the receiving frame. The receiving frame engages with the heat dissipation device to receive the cooling fluid. The receiving frame communicates with the built-in heat dissipation module and the liquid pump, such that the cooling fluid can be circulated between the built-in heat dissipation module and the receiving frame under the control of the liquid pump.
