Variable-part liquid cooling pumping unit

A liquid cooling pumping unit, comprising:

• a water block unit comprising:
• a water block set;
• a water block cover assembled to the water block set;
• and
• a flow guiding plate, assembled to and communicating with and between the water block set and water block;
• and
• a pump unit comprising:
• a chamber body mounted to and communicating with the water block cover opposite the water block set, the chamber body comprising an impeller cavity having a diameter and a flow adjusting disc opposite the mounted water block cover;
• and
• a rotor assembly unit, assembled to the chamber body opposite the water block cover, configured to increase a pressure and a flow of a working liquid flowing through the water block unit,
• wherein an inlet port and an outlet port of the liquid cooling pumping unit is positioned on a same side of and plane as the pump housing assembly, parallel to planes of the flow guiding plate and rotor assembly unit, respectively, and
• wherein the flow adjusting disc is configured to decrease turbulence of the working liquid flowing into the impeller cavity.
