Abstract
A liquid supply device includes a casing, a cover, a plunger, a driving unit and a sensing unit. The casing has a liquid outlet. The cover is connected to the casing. A chamber is formed between the casing and the cover. The chamber communicates with the liquid outlet. The plunger is movably disposed in the chamber. The driving unit is disposed in the chamber and used for driving the plunger to move. The sensing unit is selectively disposed on one of the cover and the plunger. The sensing unit outputs a sensing signal according to a current position of the plunger.
Claims13
A liquid cooling system comprising:
- a liquid supply device comprising:
- a casing having a liquid outlet;
- a cover connected to the casing, a chamber being formed between the casing and the cover, the chamber communicating with the liquid outlet;
- a plunger movably disposed in the chamber;
- a driving unit disposed in the chamber, the driving unit driving the plunger to move;
- and
- a sensing unit selectively disposed on one of the cover and the plunger, the sensing unit outputting a sensing signal according to a current position of the plunger;
- an alarm unit;
- and
- a processing unit electrically connected to the sensing unit and the alarm unit, the processing unit converting the sensing signal into a liquid level and calculating a decreasing rate of the liquid level, the processing unit controlling the alarm unit to send out an alarm message when the processing unit determines that the decreasing rate is larger than an evaporation rate.
