Description
Technical Field
The invention relates to a vertical dispenser for a server and the server.
Background
Most of computers used at present rely on cold air to cool machines, but in a data center, the air cooling alone is not enough to meet the heat dissipation requirement of a server with high heat flow density. The traditional air cooling mode is carried out by adopting an indirect contact cooling mode, the heat transfer process is complex, contact thermal resistance and convective heat transfer thermal resistance exist, the total sum of thermal resistance is large, the heat transfer efficiency is low, the temperature difference between high and low temperature heat sources in the heat transfer process is large, and the heat transfer process needs to be guided by a low outdoor low temperature heat source.
Liquid cooling utilizes a working fluid as a medium for intermediate heat transfer to transfer heat from a hot zone to a remote location for cooling. Because the specific heat of liquid is much larger than that of air, the heat dissipation speed is much higher than that of air, and therefore the refrigeration efficiency is far higher than that of air-cooled heat dissipation. Water cooling or liquid cooling has two major benefits: firstly, the coolant is directly guided to a heat source, rather than being indirectly refrigerated like air cooling; secondly, compared with air cooling, the heat transmitted by each unit volume, namely the heat dissipation efficiency, is up to 3500 times.
The biggest characteristics of liquid cooling system have two: the heat and low noise operation of the CPU are equalized. Because the specific heat capacity of the liquid is overlarge, a large amount of heat can be absorbed, the temperature can not be obviously changed, the temperature of a CPU in a liquid cooling system can be well controlled, and sudden operation can not cause instantaneous and large-amplitude change of the internal temperature of the CPU. Because the surface area of the heat exchanger is very large, the heat exchanger can achieve good effect only by radiating the heat by a fan with low rotating speed, and most of liquid cooling is matched with the fan with low rotating speed. In addition, the operating noise of the pump is generally not noticeable, so that the overall heat dissipation system is very quiet compared to an air-cooled system.
Evaporative cooling uses the latent heat of vaporization of a refrigerant when it boils to remove heat from the refrigerant in thermal principle. Since the latent heat of vaporization of liquid is much greater than that of heat, the cooling effect of evaporative cooling is more significant.
In the liquid cooling system, no matter water cooling or refrigerant cooling, no matter indirect liquid cooling system or direct immersion type liquid cooling system, no matter the CPU is cooled by using the temperature difference of the refrigerant, or evaporation cooling is performed by using the phase change principle, and a liquid distribution unit is needed before water or the refrigerant enters the server knife box. The liquid distribution unit distributes the cold fluid evenly to each knife box in the cabinet, called a vertical liquid distributor.
In the liquid cooling server in-service use, because power transmission and distribution unit PDU still has in the rack, when installing in limited rack space, both often can interfere each other, bring the difficulty to the actual equipment use of liquid cooling server.

Detailed Description
Referring now to the drawings, the present invention is described, and as shown in fig. 1 and 2, the present invention provides a vertical dispenser 10 for a server, the vertical dispenser 10 including a frame 12, a dispensing port 14, and a power interface 16.
Specifically, as shown in the figure, the liquid separation port 14 and the power interface 16 are respectively arranged on the surface of the frame 12, the power interface 16 is electrically connected with an external power supply, and a pipeline 18 for supplying refrigerant to the liquid separation port 14 is arranged inside the frame 12. Thus, the vertical liquid separator 10 of the present invention can simultaneously transport and supply the refrigerant, and has the functions of liquid separation and power distribution.
As further shown, in a preferred embodiment of the present invention, a plurality of dispensing ports 14 and a plurality of power interfaces 16 are disposed on the frame 12. Preferably, the structure of the dispensing ports 14 are the same or different from one another, and the structure of the power source interfaces 16 are different or at least partially the same as one another. It will of course be appreciated that the configuration and number of dispensing ports 14 and power interfaces 16 may be varied depending upon the particular application, and the invention is not limited thereto.
As shown in fig. 2, in one embodiment of the invention, the conduit 18 is housed inside the frame 12, and the conduit 18 includes a plurality of branches 20 corresponding one-to-one to the number of dispensing ports 14. As further shown, the frame 12 includes outer sidewalls and an interior cavity bounded by the outer sidewalls, wherein the tubing 18 is disposed in the interior cavity and the dispensing port 14 and power interface 16 are disposed on the outer sidewalls. Preferably, the dispensing port 14 and the power interface 16 are disposed on different surfaces of the outer sidewall.
In addition, the power interface 16 is electrically connected to an external power source via power lines, and the power lines are received within the interior cavity of the frame 12.

In the present invention, the vertical dispenser and the PDU (power distribution unit) are integrated, i.e., share a frame structure, for easy installation and use. On an integrated PCU (liquid separation and power distribution unit), there are both liquid separation interfaces for feeding to the horizontal liquid separators and also interfaces for power supply to supply power to the servers in the cabinet. In practice, the liquid cooling connector and the power connector may be distributed on different sides of the dispenser to prevent liquid from flowing into the interface when liquid leaks.
In the specific use process of the invention, the server adopts indirect liquid cooling. The indirect cooling type is a type in which the refrigerant is separated from the object to be cooled and does not directly contact the object to be cooled, and heat of the object to be cooled is transferred to the refrigerant by a high-efficiency heat transfer member such as a liquid cooling plate or a liquid cooling header.
In the server of the present invention, there are a horizontal distribution unit of the refrigerant and a vertical distribution unit of the refrigerant therein. During the working process of the liquid cooling heat dissipation system, the refrigerant enters and exits the refrigerant vertical distribution unit through the refrigerant inlet pipe header pipe joint and the refrigerant outlet pipe header pipe joint, then the refrigerant is distributed to the horizontal distribution unit through the vertical distribution unit, and finally the refrigerant is distributed to the tail end execution device (liquid cooling radiating fin). The refrigerant enters the blade server through a pipeline, after cooling the CPU, the temperature of the refrigerant rises or is gasified, the refrigerant enters the horizontal distribution unit again through an outlet pipe above the blade server, then the refrigerant is collected and enters the vertical distribution unit, the refrigerant is cooled with the assistance of an external cooling device, and then the refrigerant enters the vertical liquid distributor again, so that the refrigeration cycle is completed.
In summary, in the vertical liquid separator and the server of the invention, the liquid separating port and the power interface are arranged on the surface of the frame, the power interface is electrically connected with the external power supply, and the pipeline for supplying the refrigerant to the liquid separating port is arranged in the frame, so that the vertical liquid separator can simultaneously convey and supply the refrigerant, and has the functions of liquid separating and power distribution.
