Patent Description:
The present specification relates to the technical field of cooling devices, and in particular, to a cooling cabinet and a cooling system.

With the rapid development of cloud computing technology (i.e., large-scale distributed system technology), the requirements for computing performance of servers are getting increasingly higher. While server performance is improving, power consumption is increasing rapidly, and the power consumption of the cabinet has increased exponentially. The data shows that the power density of data center cabinets has increased by nearly <NUM> times in the past decade. In the past, the power consumption of a cabinet was generally <NUM> kW-<NUM> kW. However, some cabinets have partially reached as high as <NUM> kW-<NUM> kW.

At present, servers in data centers usually adopt the way of air conditioning and air cooling, which are consuming a large amount of energy, space and cost, and the consumption is increasing. However, with the steady increase in power density, the cooling capacity provided by many data centers is currently approaching the limit, and this trend of rapid increase in power density will have an adverse effect. Therefore, the conventional way of air conditioning and air cooling has been unable to meet the cooling demand of the servers in the data centers.

Further, there may be two first diversion outlets, which are respectively disposed on two sides of the cabinet body; there may be two second diversion portions which communicate with the two third tube bodies in one-to-one correspondence.

Further, the plurality of fourth tube bodies may include two groups arranged in a staggered manner; one group of the fourth tube bodies and one of the third tube bodies may be integrally formed, and the other group of the fourth tube bodies and the other third tube body may be integrally formed.

In the case of no conflict, the features in the following embodiments and implementations may be combined with each other.

Referring to <FIG>, an embodiment of the present specification provides a cooling cabinet <NUM> adopting a single-phase immersion liquid cooling technology for cooling a to-be-cooled device <NUM>. The to-be-cooled device <NUM> may be a server in a data center, or may be other heating devices that need to be cooled. The cooling cabinet <NUM> includes a cabinet body <NUM>, a first diversion assembly <NUM> and a second diversion assembly <NUM>. The cabinet body <NUM> may contain a non-conductive cooling medium for at least partially immersing the to-be-cooled device <NUM>, and the cabinet body <NUM> is provided with a first diversion inlet <NUM> for introducing the cooling medium and a first diversion outlet <NUM> for discharging the cooling medium. The first diversion assembly <NUM> is provided in communication with the first diversion inlet <NUM>, and the first diversion assembly <NUM> is provided with a second diversion outlet <NUM> for discharging the cooling medium into the cabinet body <NUM>; after flowing through the to-be-cooled device <NUM>, the cooling medium can cool the to-be-cooled device <NUM>. The second diversion assembly <NUM> is provided in communication with the first diversion outlet <NUM>, and the second diversion assembly <NUM> is provided with a second diversion inlet <NUM> for introducing the cooling medium flowing through the to-be-cooled device <NUM>. Optionally, the first diversion assembly <NUM> and the second diversion assembly <NUM> are both disposed in the cabinet body <NUM>, and the first diversion assembly <NUM> and the second diversion assembly <NUM> are respectively located on two sides of the to-be-cooled device. In the example shown in the figures, the first diversion assembly <NUM> and the second diversion assembly <NUM> are respectively located on two sides of the to-be-cooled device in the vertical direction, so that the flow field of the cooling medium is a straight path in the vertical direction, which can avoid extra energy consumption due to gravity when the cooling medium moves in the lateral direction. It should be noted that the cooling medium may completely immerse the to-be-cooled device <NUM>, or may partially immerse the to-be-cooled device <NUM>, which may be set according to actual needs.

In this embodiment, the cooling medium completely immerses the to-be-cooled device <NUM>, and the cooling medium is a liquid <NUM> electronic fluorinated liquid. The cooling medium is discharged into the cabinet body <NUM> through the first diversion assembly <NUM>, and the cooling medium flowing through the to-be-cooled device <NUM> is discharged out of the cabinet body <NUM> through the second diversion assembly <NUM>. However, in other embodiments, it is also feasible that the first diversion assembly <NUM> is provided in communication with the first diversion outlet <NUM>, and the second diversion assembly <NUM> is provided in communication with the first diversion inlet <NUM>. The setting is equivalent to introducing the cooling medium into the cabinet body <NUM> through the second diversion assembly <NUM>, and discharging the cooling medium flowing through the to-be-cooled device <NUM> out of the cabinet body <NUM> through the first diversion assembly <NUM>.

As can be seen from the above technical solution, in the cooling cabinet <NUM> of the present specification, the cooling medium enters the cabinet body <NUM> from the first diversion inlet <NUM> of the cabinet body <NUM> and is then discharged to the to-be-cooled device <NUM> through the second diversion outlet <NUM> of the first diversion assembly <NUM>; the cooling medium flowing through the to-be-cooled device <NUM> takes away the heat of the to-be-cooled device <NUM>, and then enters the second diversion assembly <NUM> through the second diversion inlet <NUM> of the second diversion assembly <NUM>, and finally is discharged out of the cabinet body <NUM> through the first diversion outlet <NUM> of the cabinet body <NUM>. In this way, the purpose of dissipating the heat of the to-be-cooled device <NUM> is achieved. By arranging the first diversion assembly <NUM> and the second diversion assembly <NUM> on two opposite sides of the to-be-cooled device <NUM>, the flow field of the cooling medium flowing through the to-be-cooled device <NUM> is a straight path, so that the entire liquid flow path of the cooling medium is the shortest, the resistance is the smallest, and the energy consumption required to drive the liquid is correspondingly greatly reduced, thereby achieving the effect of minimum energy consumption. In addition, the cooling medium flows along a linear flow path, and cold and hot fluids are completely isolated, which can prevent the cold and hot fluids from mixing with each other, thereby achieving the optimal cooling effect.

For example, the cross-sectional structure of the to-be-cooled device <NUM> is rectangular, and the tube bank structure of the tube bank portion <NUM> is a rectangular tube bank structure corresponding to the cross-sectional structure.
