A liquid cooling device for a server with an adjustable return tank for central jetting

Abstract

The invention discloses a liquid cooling device for a server with an adjustable middle injection liquid return tank, which relates to the technical field of heat dissipation for servers. The device includes a box body and an upper cover. The inner space of the box is sequentially divided into a liquid storage buffer zone and an immersion zone from left to right. A plurality of servers are fixedly arranged sequentially from front to back in the immersion area. The tank body is respectively provided with a first liquid inlet pipe and a liquid return pipe connected with the immersion area and the liquid storage buffer area, and the liquid return pipe is connected with the first liquid inlet pipe through a pipeline, and A cooling device and a liquid storage tank are connected in series on the pipeline. The middle part of the right side plate of the box body is provided with a liquid distribution pipe, and the left side of the liquid distribution pipe is provided with liquid spray ports corresponding to the servers one by one. The device not only improves the heat dissipation effect but also solves the problem of local heating by increasing the fluidity of the local cooling liquid in a targeted manner without increasing the displacement of the pump.

Description

Technical field[0001]The present invention relates to the field of heat dissipation techniques, and in particular, a central injection can regulate the liquid cooling device.Background technique[0002]With the rapid development of mobile data, cloud computing and large data services, data center construction is getting bigger and larger, and the data center owner's demand for energy saving of data centers has gradually highlighted. In recent years, many data centers have emerged, with the generation of direct immersion liquid-cooled servers in electronic refrigerant techniques, high availability, high density, ultra-low PUE, etc. Technical cognition for energy saving consumption consumption of data centers.[0003]Direct immersion liquid-cooled servers are completely immersed in coolant, with good heat dissipation effect, but there is still the following technical problems on the current immersion liquid cooling servers.[0004]First, the direct immersion liquid-cooled server is complete...

AI Technical Summary

Problems solved by technology

[0004] First, because the direct immersion liquid cooling server is completely submerged in the cooling liquid, the amount of cooling liquid is relatively large, limited by the displacement of the pump, and the fluidity of the cooling liquid in the box is poor, which will inevitably affect the heat dissipation effect

[0005] Second, after the traditional direct immersion liquid-cooled server coolant enters the box from the liquid inlet, it flows upward evenly with the rise of the liquid level, but the heating points of the servers in the box are not uniform, so direct immersion Although the liquid cooling method is better than the traditional air cooling method, it still cannot solve the problem of local heating.
