Water block pressure regulation structure

A water block pressure regulation structure, comprising:

• a top cover having a pressure reduction chamber and an outlet and an inlet;
• the pressure reduction chamber including a water-out compartment and a water-in compartment located at positions corresponding to the outlet and the inlet, respectively;
• a partitioning plate being provided on one side with an upward extended valve receiving section consisting of a first zone and a second zone, which are communicable with each other;
• the partitioning plate being further provided with a first bore and a second bore in the first and the second zone, respectively;
• the first zone having a first valve and an elastic element provided therein for opening or closing the first bore and the second zone having a second valve provided therein for opening or closing the second bore;
• the partitioning plate being further provided outside of the valve receiving section with a first penetrating opening and a second penetrating opening;
• and the pressure reduction chamber in the top cover correspondingly covering the first and the second zone to form an independent buffer space around an outer side of the first and the second zone;
• and
• a heat absorbing member having a heat absorption surface and a heat dissipation surface;
• the partitioning plate being superposed on the heat absorbing member with a heat exchange chamber defined between the heat dissipation surface of the heat absorbing member and the partitioning plate;
• the heat exchange chamber being communicable with the water-in compartment and the water-out compartment via the inlet and the outlet, respectively, to form a cooling liquid circulation path;
• the buffer chamber and the heat exchange chamber being independent of each other but communicable via the first and the second bore only;
• wherein when the heat exchange chamber has a relatively high internal pressure or when a cooling liquid in the cooling liquid circulation path is insufficient, the first and the second valve automatically open or close the first and the second bore, respectively, to achieve regulation of pressure and replenishment of the cooling liquid in the heat exchange chamber.
