Liquid cooling heat exchange apparatus

A liquid cooling heat exchange apparatus configured to be flow through by a working fluid, comprising:

• a water block set, comprising:
• a water block, having a heat transfer surface comprising a width, configured to exchange heat with the working fluid;
• a water block cover, securely mounted on the water block facing the heat transfer surface, the water block cover comprising:
• an inlet port;
• a cover diversion opening;
• a cover outlet through hole;
• and
• an outlet port;
• and
• a surge directing plate, assembled to and communicating with and between the water block cover and water block;
• and
• a pump unit, securely mounted on the water block set, comprising:
• a rotor housing, securely mounted on and communicating with the water block cover opposite the water block, the rotor housing comprising an impeller cavity having an impeller cavity inlet and an impeller cavity outlet;
• a stator assembly, assembled to the rotor housing opposite the impeller cavity, facing the water block cover, configured to increase a pressure and flow through of the working fluid;
• and
• a pump cover, securely mounted on the rotor housing opposite the stator assembly,
• wherein the working fluid flows through the inlet port and cover diversion opening before flowing through the impeller cavity inlet and impeller cavity outlet, and then through the cover outlet through hole and throughout the heat transfer surface, and then through the outlet port, and
• wherein the inlet port and outlet port are on a same side of the water block cover, the cover diversion opening is near to the same side of the inlet and outlet ports and the cover outlet through hole is near to an opposite side of the inlet and outlet ports.
