Problems solved by technology
[0005] However, in the above-mentioned known water-cooling system, due to the phenomenon that the pipeline is too large or there is air remaining in the pipeline, etc., it is easy to cause the flow resistance of the coolant to change and affect the liquid flow.
In addition, it is known that the gas pressure in the water cooling system is mostly the ambient air pressure, which is the same as the external air pressure of the water cooling system. If the pipeline is damaged, it is easy to cause the problem of coolant leakage

The invention relates to a negative pressure water cooling system, a negative pressure monitoring device and a negative pressure monitoring method. The negative pressure water cooling system is used for pumping a cooling liquid for circulation. The negative pressure water cooling system comprises a cooling liquid box, a pump piece, a heat-sink piece, a negative pressure device and a monitoring device. The cooling liquid box is provided with a first opening, a second opening and a third opening; the first opening and the third opening are positioned below the liquid level of the cooling liquid; the second opening is positioned above the liquid level of the cooling liquid. The pump piece extracts the cooling liquid in the cooling liquid box from the first opening. The heat-sink piece is connected with the pump piece so as to allow the cooling liquid to carry out heat exchange through the heat-sink piece. The negative pressure device is connected with the third opening, and further forms a passage with the cooling liquid box. The monitoring device comprises a control unit electronically connected with the negative pressure device; a preset time value is stored in the control unit, and when the running time of the negative pressure water cooling system meets the preset time value, the control unit sends out a control signal to enable the negative pressure device to start to draw air in the passage and enable the value of air pressure inside the passage to be lower than the value of the air pressure outside the passage.
Description
【Technical field】 [0001] The invention relates to a water cooling system for electronic devices, in particular to a negative pressure water cooling system for electronic devices. 【Background technique】 [0002] The development of electronic products tends to be integrated and miniaturized, resulting in doubled heat output per unit area of electronic devices such as central processing units or chips. How to control the problems caused by a large amount of heat output, such as affecting the running speed of the product, noise, etc., is an important issue. Therefore, electronic products need a heat sink that can ensure sufficient cooling capacity in a narrow area, so that the operating temperature of each electronic component in the electronic device can be kept within a reasonable range to promote heat exchange between it and the environment, thereby protecting Electronic components, to avoid damage to electronic components or computer system crashes due to overheating. ...
