Flow adjusting device and liquid cooling cabinet

Abstract

The invention relates to the technical field of heat dissipation of electronic equipment, and discloses a flow adjusting device and a liquid cooling cabinet. The flow adjusting device comprises a partition plate which is arranged at the bottom of the liquid cooling cabinet and is provided with a plurality of open holes penetrating through the thickness of the partition plate, and plugging heads which are in one-to-one correspondence with the open holes and comprise first ends and second ends which are oppositely arranged, and the cross sectional areas of the plugging heads are gradually increased in the direction from the first ends to the second ends; the device further comprises adjusting mechanisms which are in one-to-one correspondence with the plugging heads and used for adjusting thedepths of the plugging heads extending into the open holes. In the embodiment, the partition plate divides the internal space of the cabinet body into the upper part and the lower part which are isolated from each other, cooling liquid can enter the upper-layer space only through the open holes in the partition plate, the flow of the cooling liquid entering each electronic device is changed by adjusting the flow area of the cooling liquid in the open holes, and the flow adjusting device has the advantages of being simple in structure, high in adaptability, convenient to adjust and the like.

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
