Background

With the rapid development of the communication and electronic industry, the deployment of high-density servers is a necessary trend of data center construction and development, the heat dissipation problem of the servers is more prominent than before, and if the heat dissipation problem of the servers cannot be effectively solved, the further development of the data center is influenced.

In the correlation technique, adopt immersion liquid cooling or fountain liquid cooling to reduce data center's heat dissipation capacity usually, immersion liquid cooling means: the heat dissipation element is immersed in the cooling liquid, and heat is taken away by means of the circulating flow of the cooling liquid. The spray type liquid cooling means that: the cooling liquid is sprayed on the heat dissipation elements from top to bottom in the server to absorb and take away heat.

Some embodiments of the present disclosure provide a cabinet 100. As shown in fig. 1, cabinet 100 includes an enclosure 10, a plurality of vertical servers 20, and a plurality of spray heads 30.

The housing 10 is used to provide a supporting foundation. The vertical servers 20 are disposed in the box body 10, and the plurality of vertical servers 20 are used for processing data and generating heat. A plurality of spray heads 30 are arranged in the box body 10, and each vertical server 20 comprises at least one spray head 30 along at least one side of the first direction X; the spray heads 30 are configured to spray the cooling liquid toward the side wall of the vertical server 20. Like this, the coolant liquid is sprayed on the lateral wall of vertical server 20, and the coolant liquid takes away most heat that vertical server 20 lateral wall produced to reach the purpose like this for vertical server 20 cooling, can improve the refrigeration efficiency of coolant liquid.

Illustratively, the spray head 30 may be an atomizing spray head. The atomizer can be a pressure atomizer, a rotary atomizer, a pneumatic atomizer, an ultrasonic atomizer or a whistle atomizer, and the embodiments of the present disclosure are not listed one by one. For example, the atomizer may be a pressure atomizer, such that the cooling liquid hits the sidewall of the vertical server 20 at a certain speed, the cooling liquid directly contacts the sidewall of the vertical server 20 to realize active heat exchange, and the cooling liquid takes away most of the heat generated by the vertical server 20, thereby cooling the vertical server 20.

For example, the pressure atomizing nozzle may include a thimble, and the thimble enables the pressure atomizing nozzle to be opened or closed by a certain pressure.

In some embodiments, as shown in fig. 1 to 3, the vertical server 20 includes a support plate 21, a service plate 22, and heat dissipation elements 23, illustratively, the support plate 21 and the service plate 22 are rectangular in shape, and a plurality of support plates 21 are arranged along a first direction X, which is parallel to a width direction of the support plate 21. One end of the service plate 22 is connected with one end of the support plate 21 along the second direction Y, a space is provided between the two service plates 22, and the service plate 22 comprises a first side wall 221 and a second side wall 222 which are oppositely arranged along the first direction X; the first direction X is perpendicular to the second direction Y. A plurality of heat dissipation elements 23 are disposed on the first sidewall 221 of the service plate 22. Wherein the shower head 30 is configured to spray the cooling liquid toward the first sidewall 221 of the service plate 22, and the shower head 30 is spaced apart from the first sidewall 221 in the first direction X. Thus, the area of the cooling liquid sprayed onto the first sidewall 221 by the spray head 30 is large, and the number of spray heads can be reduced.

In some embodiments, the first sidewall 221 and the second sidewall 222 of a plurality of service plates 22 have the same arrangement along the first direction X, and at least one showerhead 30 is included between two adjacent service plates 22. In this way, the risk of interference between spray heads 30 may be reduced.

Illustratively, as shown in fig. 2, the first side wall 221 and the second side wall 222 of the plurality of service boards 22 having the same arrangement order refer to: the first side wall 221 of each service panel 22 is located to the left of the second side wall 222.

In some implementations, the heat dissipation element 23 may include one or more of an optical module, a main control transmission module, a channel Processing board, a communication power supply module, a Central Processing Unit (CPU), and a Graphics Processing Unit (GPU). Embodiments of the disclosure are not listed one by one.

Illustratively, the central processing units are divided into a first central processing unit and a second central processing unit, and the graphics processing unit is also divided into a first graphics processing unit and a second graphics processing unit. The first cpu and the first graphic processor are used for overcomputing, have high power consumption and high heat dissipation capacity, and are high-density heat dissipation elements 23. The high-density heat dissipation element 23 may further include a main control transmission module and a channel processing board. The second cpu and the second graphic processor are used for general power calculation, power consumption centering, heat dissipation centering, and are the dense heat dissipation elements 23. The medium dense heat dissipating element 23 may further include a communication power supply module. The optical module has low power consumption and low heat dissipation, and is a low-density heat dissipation element 23. The distribution density of the nozzles 30 corresponding to the high-density heat dissipation elements 23 is high density, the distribution density of the nozzles 30 corresponding to the medium-density heat dissipation elements 23 is medium density, and the distribution density of the nozzles 30 corresponding to the low-density heat dissipation elements 23 is low density. The position where the distribution density of the heat radiating members 23 is high corresponds to the division density of the heads 30 being high. The distribution density of the heat dissipation elements 23 is middle density, which corresponds to the position of the spray head 30. The position where the distribution density of the heat radiating members 23 is low corresponds to the division density of the heads 30 being low.

In this way, the density distribution of the plurality of heads 30 is adapted to the distribution density and the work load of the plurality of heat radiating elements 23. The cooling liquid can accurately cool the side wall of the vertical server 20, and the risk that the high-density radiating element 23 is not timely cooled and the low-density radiating element 23 is excessively cooled can be reduced. The refrigeration efficiency of the cooling liquid can be further improved.

In this way, the resistance of the coolant in the distributor 40 to flow into each spray head 30 can be reduced.

For example, as shown in fig. 3, one liquid supply hose 50 may be connected to one spray head, or one liquid supply hose 50 may be connected to a plurality of spray heads, which is not limited in the embodiments of the present disclosure. The liquid supply hose 50 has strong oxidation resistance and high temperature resistance. Thus, the liquid supply hose 50 can be used in the case of high power consumption and high heat dissipation of the vertical server 20. For example, the liquid supply hose 50 may be made of polyphenylene sulfide, poly-p-phenylene terephthalamide, or polyamide fiber, and the examples of the disclosure are not illustrated.

The drip pan 60 is disposed at the bottom of the plurality of vertical servers 20 and spaced apart from the plurality of vertical servers 20, and is configured to collect the cooling liquid for recycling.

The machine room cooling system 1000 further comprises a water circulating pump 600, and the water circulating pump 600 is arranged on the liquid return pipeline 500. The circulating water pump 600 delivers the cooling liquid in the liquid collecting tray 60 to the liquid distributing tray 40, so as to improve the utilization efficiency of the cooling liquid.

The coolant sprayed on the vertical servers 20 absorbs heat and flows back to the liquid collecting tray 60 under the action of gravity, the coolant in the liquid collecting tray 60 flows into the first coolant passage 310 in the process of flowing back to the liquid collecting tray 60 or in the liquid collecting tray 60, the coolant in the cooling tower 200 flows into the second coolant passage 320 through the first coolant outlet 220, the coolant in the first coolant passage 310 exchanges heat with the coolant in the second coolant passage 320, the temperature of the coolant is reduced, the temperature of the coolant is increased, the cooled coolant is conveyed into the liquid distributing tray 40 through the liquid supply pipeline 400 and then flows into each spray head 30 and then is sprayed onto the side wall of the vertical servers 20, the coolant after cooling of coolant circulation is conveyed into the liquid distributing tray 40, and the coolant with the increased temperature is conveyed into the cooling tower 200 through the second coolant passage 320 and the first coolant inlet 210, so that coolant circulation is completed.
