The invention discloses a
liquid cooling system utilizing condensation heat to be self-adaptive to refrigerating capacity, and the
system comprises a refrigerating
system and a cooling liquid circulating
system; the refrigerating system comprises a compressor, a condenser, an expansion valve and an
evaporator, which are sequentially and circularly connected with one another, and the
evaporator is provided with a liquid return inlet and a liquid return outlet; the cooling liquid circulating system comprises a solution tank which is connected with the liquid return outlet of the
evaporator, and the liquid return inlet of the evaporator and an outlet of the solution tank are respectively connected with a user side; and an air outlet of the compressor is connected with an air distributing valve, a liquid inlet of the expansion valve is connected with a liquid
inlet valve, a
heat exchanger is arranged inside the solution tank, the air distribution valve is connected with an inlet of the
heat exchanger, and the liquid
inlet valve is connected with an outlet of the
heat exchanger. The condensation heat discharged by the compressor is used for heating solution inside the solution tank, simultaneously the low-temperature liquid
refrigerant after the heat exchanging and the normal-temperature high-pressure liquid
refrigerant discharged by the condenser enter the evaporator to exchange heat and evaporate. By controlling the flow situation of the
refrigerant and the solution, the supplementary cooling amount of the solution inside the solution tank can be controlled.
