Because coolant liquid is reserved in each part of the whole system, the pipeline interface and the liquid storage tank 04, absolute air tightness cannot be achieved, small gaps possibly exist at the connecting interface to allow air circulation, and small-molecule coolant liquid can slowly diffuse and volatilize into the air through parts such as water pipes and connectors, so that the coolant liquid in a cold system can be reduced along with the application of a liquid cooling heat dissipation system, the air in a water tank and the system can be gradually increased, and larger bubbles are accumulated. Meanwhile, in order to improve the cooling effect, the cooling liquid needs to flow in a circulating mode in the system, the cooling liquid in the system evaporates or volatilizes to cause the liquid level of the water tank to be reduced, a large amount of bubbles are generated after the backflow liquid impacts the liquid level of the water tank, the bubbles are difficult to dissolve in the cooling liquid at one time, and the cooling liquid in the water tank is quickly pumped away to perform cooling circulation.
Air bubbles contained in the cooling liquid can cause failure to occur: 1. when the bubbles collapse, liquid particles collide with each other and also collide with the metal surface, noise with various frequencies is generated, and when the noise is serious, the explosion sound of 'crack' in the pump can be heard, and meanwhile, the unit vibrates; 2. cavitation occurs and the performance of the pump is reduced. Cavitation is the phenomenon of cavitation corrosion damage on the metal surface contacted with fluid under the conditions of high-speed flow and pressure change of the fluid. A large amount of bubbles are generated in the liquid cooling system to block a flow channel, so that the continuous flow of liquid in the pump is damaged, and the flow, the lift and the efficiency of the pump are obviously reduced; 3. the overflowing part is damaged, because of the action of mechanical ablation, the part damaged by cavitation is mostly near the outlet of the impeller, and the surface of the impeller presents the marks of sponge, groove, honeycomb, fish scale and the like; in severe cases, the blades or the front and rear cover plates may be perforated, and even the impeller of the circulation pump may be damaged.
