The outlet of the first water pump 2 is arranged horizontally through a first connecting groove 4. The end of the first connecting groove 4 extends upward and is provided with an outlet connector 5 for connecting to an outlet pipe. The outlet of the second water pump 3 is arranged vertically and connected to the inlet of the water duct body 1. The inlet of the second water pump 3 is arranged horizontally through a second connecting groove 6. The end of the second connecting groove 6 extends upward and is provided with an inlet connector 7 for connecting to an inlet pipe. The main body 1 of the water drain includes a first water storage chamber 8, a second water storage chamber 9, a third water storage chamber 10 for refrigerant circulation, and multiple cooling pipes 11. The first water storage chamber 8 and the third water storage chamber 10 are located at one end of the main body 1, and the second water storage chamber 9 is located at the other end. The multiple cooling pipes 11 are divided into two groups. One group of cooling pipes 11 connects the first water storage chamber 8 and the second water storage chamber 9, and the other group of cooling pipes 11 connects the second water storage chamber 9 and the third water storage chamber 10. The inlet and outlet directions of the first water pump 2 and the second water pump 3 are perpendicular. Compared with the conventional structure where they are arranged in parallel, the water pumps fit more closely to the main body 1, and the two water pumps are respectively located at the inlet and outlet ends of the main body 1, which significantly increases the overall head and greatly improves the heat dissipation performance. Placing both the first water pump 2 and the second water pump 3 on the water drain not only makes the connection structure more stable, aesthetically pleasing, and space-saving, but also facilitates the installation of the main body 1 and the layout of the water pipes.

[0027] Specifically, the first water pump 2 includes a first mounting base 12, a first motor 13, and a first impeller 14. The first mounting base 12 is located on top of the first water storage chamber 8, and the first motor 13 is located on top of the first mounting base 12. The first mounting base 12 has a first connecting groove 4 and a first chamber 23 for accommodating the first impeller 14.

[0031] In operation, the first impeller 14 and the second impeller 17 rotate synchronously, the first water pump 2 pumps the refrigerant from the water discharge body 1 to the water cooling head, and the second water pump 3 pumps the refrigerant from the water cooling head to the water discharge body 1. Specifically, the first motor 13 drives the first impeller 14 to rotate, and the low-temperature refrigerant is sucked from the first water storage cavity 8 to the first cavity 23, and then pumped from the first cavity 23 to the first communication groove 4, and the low-temperature refrigerant flows from the water outlet connector 5 to the water cooling head; after the low-temperature refrigerant is heated to high-temperature refrigerant after heat exchange in the water cooling head, the second motor 16 drives the second impeller 17 to rotate, and the high-temperature refrigerant is sucked from the water inlet connector 7 to the second cavity 24 through the second communication groove 6, and then pumped from the second cavity 24 to the third water storage cavity 10, and then flows from the third water storage cavity 10 to the second water storage cavity 9 through the cooling pipe 11, from the second water storage cavity 9 to the first water storage cavity 8 through the cooling pipe 11, and is cooled to low-temperature refrigerant, and then flows to the water cooling head under the pumping of the first water pump 2, so as to circulate and heat exchange.
