1. A water cooling structure, comprising:
a plurality of water cooling heads, each of the plurality of water cooling heads comprising a housing, and the housing comprising a water inlet and a water outlet;
a plurality of connectors, each comprising a first connecting tube connected to the water inlet or the water outlet, and a second connecting tube formed substantially perpendicularly to the first connecting tube;
a plurality of connecting pipes, connected between any two adjacent water cooling heads, and each of the plurality of connecting pipes comprising one end connected substantially in parallel with a bottom surface of the housing to the second connecting tube of the connector installed in the water inlet of one of the two adjacent water cooling heads and another end connected substantially in parallel with the bottom surface of the housing to the second connecting tube of the connector installed in the water outlet of another one of the two adjacent water cooling heads to connect the water cooling heads in line with a series connection;
a water-inlet pipe, having one end connected substantially in parallel with the bottom surface of the housing to the second connecting tube of the connector installed in the water inlet of one of the water cooling head located outermost in the water cooling heads, and another end connected substantially in parallel with the bottom surface of the housing to a water-inlet pump; and
a water-outlet pipe, having one end connected substantially in parallel with the bottom surface of the housing to the second connecting tube of the connector installed in the water outlet of another one of the water cooling heads located outermost in the water cooling heads, and another end connected substantially in parallel with the bottom surface of the housing to a water-inlet pump;
wherein the housing comprises a lower seat and an upper seat, and the lower seat comprises a lower chamber;
a plurality of water cooling fins are disposed in the lower chamber; and
the upper seat comprises the water inlet and the water outlet, and the upper seat is combined with the lower seat to cover the lower chamber;
wherein the water inlet and the water outlet are located in the upper seat and above a middle of the plurality of water cooling fins to facilitate working fluid inside the water cooling head flowing uniformly, and a gap is formed between a top side of the plurality of water cooling fins and the water inlet and the water outlet.
