A flow regulating device and a liquid cooling cabinet

Abstract

The invention relates to the technical field of heat dissipation of electronic equipment, and discloses a flow regulating device and a liquid cooling cabinet. The flow regulating device includes: a partition, which is used to be arranged at the bottom of the cabinet of the liquid-cooled cabinet, and is provided with a plurality of openings passing through its thickness; a sealing head, corresponding to the openings one by one, including a first end oppositely arranged and the second end, and along the direction from the first end to the second end, the cross-sectional area of ​​the plugging head gradually increases; the adjustment mechanism corresponds to the plugging head one by one, and is used to adjust the depth of the plugging head extending into the opening. In the above embodiment, the partition divides the space inside the cabinet into two parts, the upper and lower parts, and the coolant can only enter the upper space through the openings on the partition. The coolant flow rate inside each electronic device has the advantages of simple structure, strong adaptability, and convenient adjustment.

Description

Technical field [0001] The present invention relates to the field of heat dissipation technology for electronic devices, in particular to a flow regulation device and a liquid-cooled cabinet. Background [0002] At present, due to the continuous innovation of science and technology, electronic equipment is developing in the direction of large power consumption and small volume, traditional air cooling due to the limitation of heat dissipation capacity, has been unable to meet the heat dissipation needs of electronic equipment, and immersion liquid cooling technology, due to its high efficiency and energy saving, low construction costs and other advantages, has become a new trend in the development of heat dissipation technology.

Problems solved by technology

[0002] At present, due to the continuous innovation of science and technology, electronic equipment is developing in the direction of large power consumption and small volume. Due to the limitation of heat dissipation capacity, traditional air cooling can no longer meet the heat dissipation requirements of electronic equipment, while immersion liquid cooling technology, then Due to its advantages of high efficiency, energy saving and low construction cost, it has become a new trend in the development of heat dissipation technology.

[0003] In immersion liquid cooling, the cooling liquid is usually fluorinated liquid, silicone oil, etc. This type of cooling liquid has good insulation properties, but its viscosity is high and its density is high, which will cause greater resistance when flowing in the cabinet. The greater the number of electronic devices in the cold cabinet, the greater the difference in flow into each electronic device. When electronic devices with different power consumption are placed in the cabinet at the same time, the difference in heat dissipation effect of each electronic device will be more obvious.

[0004] At present, research on the flow regulation of submerged liquid-cooled fluids mainly includes two aspects: cabinet structure improvement and centralized control. Starting from the cabinet structure, the overall structure has changed a lot, and electronic devices with different power consumption need to be designed correspondingly. structure, poor adaptability; starting from the control aspect, there are problems such as difficult control, high cost, and large size of the control device
