Abstract
A liquid cooling heat dissipation system is disclosed, including: a primary side cooling unit, a secondary side cooling unit and a heat exchange unit, wherein an outlet of the primary side cooling unit is in communication with a primary side inlet of the heat exchange unit, and a primary side outlet of the heat exchange unit is in communication with an inlet of the primary side cooling unit.
Claims19
A liquid cooling heat dissipation system, comprising a primary side cooling unit, a secondary side cooling unit and a heat exchange unit, wherein an outlet of the primary side cooling unit is in communication with a primary side inlet of the heat exchange unit, and a primary side outlet of the heat exchange unit is in communication with an inlet of the primary side cooling unit;
- and the secondary side cooling unit comprises a pump drive unit, a static pressure water tank and a load unit, wherein an inlet of the pump drive unit is in communication with an outlet of the load unit, an outlet of the pump drive unit is in communication with the static pressure water tank, the static pressure water tank is in communication with the atmosphere and is also in communication with a secondary side inlet of the heat exchange unit, a secondary side outlet of the heat exchange unit is in communication with an inlet of the load unit, and the pump drive unit is a water pump for pumping water to an inlet side of the pump drive unit;
- wherein the secondary side cooling unit comprises a secondary side liquid return unit, wherein the secondary side liquid return unit comprises an exhaust tank, a bottom outlet of the static pressure water tank and the outlet of the load unit are both in communication with a top inlet of the exhaust tank, a bottom outlet of the exhaust tank is in communication with the inlet of the pump drive unit, and a pressure-stabilizing exhaust valve is provided at a top of the exhaust tank.
A liquid cooling heat dissipation system, comprising:
- a pump drive unit configured to perform a water pumping operation on a line on an inlet side of the pump drive unit, such that a line flowing from a static pressure water tank to the pump drive unit in a secondary side cooling unit is in a negative pressure state to form a negative pressure line;
- a static pressure water tank in communication with ambient atmospheric pressure and configured to establish a pressure difference between the ambient atmospheric pressure and the negative pressure in the negative pressure line to establish a circulation flow power of the coolant in the secondary side cooling unit via the pressure difference;
- and
- a load unit configured to deliver a low-temperature coolant to a load and performing heat exchange with the load under the circulation flow power to form a high-temperature coolant;
- wherein the secondary side cooling unit comprises a secondary side liquid return unit, wherein the secondary side liquid return unit comprises an exhaust tank, a bottom outlet of the static pressure water tank and the outlet of the load unit are both in communication with a top inlet of the exhaust tank, a bottom outlet of the exhaust tank is in communication with the inlet of the pump drive unit, and a pressure-stabilizing exhaust valve is provided at a top of the exhaust tank.
