Provided is a water cooling type cooling system for an electronic device having a plurality of coolant circulation units and coolant supply units separable from each other to be interconnected in series or parallel. The water cooling type cooling system includes a coolant circulation unit including heat exchangers contacting heat sources inside the electronic device and internal circulation lines disposed inside the electronic device for circulating a coolant in the heat exchangers, a coolant supply unit including external circulation lines connected to the internal circulation lines of the coolant circulation unit and extending outside the electronic device so as to circulate the coolant outside the electronic device, heat-dissipating devices connected to the external circulation lines for emitting heat of the coolant into the air, circulation pumps connected to the external circulation lines for forming hydraulic pressure of the coolant, a coolant tank in which the coolant is stored, and a casing for protecting the heat-dissipating devices, the circulation pumps and the coolant tank, and a controller for controlling the circulation pumps by applying control signals to the circulation pumps. Therefore, components inside the electronic device are simplified, thereby facilitating assembling and maintenance works and reducing the internal temperature of the electronic device. Also, noise and vibration of the electronic device can be reduced. Further, since a plurality of small-sized electronic components are interconnected in series or parallel, a detachable, rack mount type, large-sized electronic device can be operated in a water cooling type.
