Background
With the development of the electronic technology in China, more and more electronic devices have been widely used.
Servers are important components in electronic devices, and are devices that provide computing services. Since the server needs to respond to and process the service request, the server generally has the capability of assuming and securing the service. The server is divided into a file server, a database server, an application server, a WEB server and the like according to different service types provided by the server. The main components of the server include a processor, a hard disk, a memory, a system bus, etc., similar to a general-purpose computer architecture, but the server needs to provide highly reliable services, and thus has high requirements on processing capability, stability, reliability, security, scalability, manageability, etc.

However, in the conventional immersed liquid cooling heat dissipation method, after the server is immersed in the cooling tank, the flow rate of the cooling liquid entering the cooling tank is low, and the flow rate is low when the cooling liquid flows to the server, so that the fluid disturbance effect is weak, the turbulence degree is low, the fluidity is poor, the heat exchange efficiency is low, and the server cannot be cooled quickly.
Therefore, how to improve the flow disturbance effect of the cooling liquid at the server, enhance the turbulence degree and the flow performance, and improve the heat exchange cooling efficiency is a technical problem faced by those skilled in the art.

The liquid inlet pipe 3 is communicated with the upper area of the box body 1 and is mainly used for introducing cooling liquid which flows circularly. The liquid outlet pipe 4 is connected to the lower region of the casing 1, and is mainly used for discharging the cooling liquid which flows circularly and absorbs the heat of the server.
Shunt tubes 5 are core components, and specifically distribute on the inner wall of box 1, are provided with many simultaneously generally to each shunt tube 5 all keeps the intercommunication with feed liquor pipe 3, can make during coolant liquid gets into respectively after box 1 from feed liquor pipe 3 flows into each shunt tube 5, realizes the reposition of redundant personnel effect.
Meanwhile, each of the flow dividing pipes 5 is provided with a plurality of spray holes 51, and each of the spray holes 51 faces the server, and is mainly used for accelerating the pressurized spraying of the cooling liquid in the flow dividing pipe 5 to the server by reducing the sectional area of the flow passage.
So, the submergence formula cooling install bin that this embodiment provided, because the coolant liquid is sprayed to server department with higher speed pressurization after through jet orifice 51, consequently can improve the fluid disturbance effect of coolant liquid in server department by a wide margin, strengthen turbulent degree and flow property, and then improve heat transfer cooling efficiency.
In an alternative embodiment regarding the box 1, considering that the server is generally rectangular, the box 1 is specifically rectangular, such as square or rectangular, etc. to facilitate the installation of the server.
In an optional embodiment of the mounting rails 2, in order to facilitate the taking, placing, dismounting and mounting operations of the servers in the box 1, each mounting rail 2 is connected between two sidewalls of the top of the box 1 along the horizontal direction, so that each server is inserted into the box 1 along the vertical direction, and vertical insertion is realized. Generally, the installation sliding rails 2 can be simultaneously arranged at 2 positions and respectively distributed at two side positions of the box body 1, so as to be conveniently connected with two side walls of the server in a sliding manner.
Furthermore, each installation slide rail 2 can all distribute along the length direction of box 1, so each installation slide rail 2 sets up respectively in the width direction both sides position of box 1 promptly, and the length direction both ends of each installation slide rail 2 link to each other with the front and back end inner wall of box 1 respectively, and then make each server along the length direction align to grid of box 1, realize the range upon range of installation in the horizontal direction.
Correspondingly, for making the coolant liquid spout the back and can flow to server department fast from the orifice 51, in this embodiment, the direction of distribution of each shunt tubes 5 and the installation direction phase-match of server, each shunt tubes 5 also all distributes on the inner wall of box 1 along vertical direction promptly, and simultaneously, each orifice 51 is along its length direction align to grid on shunt tubes 5, distributes along vertical direction equally promptly. So set up, spout simultaneously in each spout hole 51 behind the coolant liquid, the coolant liquid can cover the whole vertical direction region of server simultaneously to improve cooling efficiency.
Further, in view of the same, since the servers are arranged along the longitudinal direction of the mounting rail 2 and the mounting rail 2 is arranged along the longitudinal direction of the casing 1, the respective branch pipes 5 are arranged along the longitudinal direction of the casing 1 in the present embodiment, and the cooling liquid can be sprayed to the plurality of servers at the same time.
Generally, the respective branch pipes 5 are simultaneously distributed on both inner walls in the width direction of the casing 1 so as to be able to spray the cooling liquid to both sides of the respective servers at the same time. In order to make the cooling liquid quickly enter into each shunt pipe 5 after being introduced from the liquid inlet pipe 3, a liquid inlet loop pipe 6 is added in the embodiment.
Specifically, the liquid inlet loop 6 is disposed at the top of the tank 1, and is in a ring shape, such as a rectangular ring shape, and is circumferentially distributed on each inner wall of the tank 1. One end or two ends (or multiple ends) of the liquid inlet ring pipe 6 are communicated with the liquid inlet pipe 3, and the top pipe orifices of the shunt pipes 5 are respectively communicated with different positions of the liquid inlet ring pipe 6. So set up, after coolant liquid got into feed liquor pipe 3, will at first form the netted runner of annular along feed liquor ring canal 6 to in flow process enters into each shunt tubes 5 respectively, in order to make the coolant liquid divide the reposition of redundant personnel fast and enter into different shunt tubes 5, improve the flow efficiency of coolant liquid.
In addition, in order to ensure that the cooling liquid in the tank body 1 is kept within a predetermined range for a long time, the liquid equalizing tank 7 and the liquid level sensor are additionally arranged in the embodiment.
Wherein, level sensor mainly used detects the real-time liquid level in the box 1.

Meanwhile, an overflow pipe 71 is provided on the homogenization tank 7 and is in communication with the upper region of the tank 1 through the overflow pipe 71, and the communication position is high and generally exceeds a preset threshold (upper limit). So set up, when the coolant liquid in box 1 is too much and the liquid level surpassed preset threshold value, excessive coolant liquid will be stored to automatic overflow to the samming case 7 in through overflow pipe 71.
Further, the coolant in the tank 1 may overflow due to an excess, or may not submerge the server, and for this reason, the liquid replenishment pipe 72 is additionally provided to the liquid equalizing tank 7 in the present embodiment. Specifically, the liquid equalizing tank 7 is communicated with the lower area of the tank body 1 through the liquid supplementing pipe 72, and a control valve for controlling the on-off of the pipeline is arranged at the pipe orifice of the liquid supplementing pipe 72 and is in signal connection with the liquid level sensor. Under normal conditions, the liquid level of the cooling liquid in the box body 1 is above a preset threshold (lower limit), the control valve is kept closed, and the cooling liquid in the liquid equalizing box 7 cannot flow into the box body 1 through the liquid supplementing pipe 72; when the amount of the cooling liquid is insufficient, the liquid level of the cooling liquid in the tank body 1 is below a preset threshold (lower limit), at this time, the liquid level sensor sends a corresponding control instruction to the control valve to open the valve of the control valve, and the cooling liquid in the liquid equalizing tank 7 flows into the tank body 1 through the liquid supplementing pipe 72 to supplement the flow rate of the cooling liquid in the tank body 1.
In addition, considering that the coolant is ejected from each of the ejection holes 51 and then flows out from the liquid outlet pipe 4 with a large kinetic energy and pressure, which may affect components such as an external heat exchanger, the present embodiment adds the flow equalizing plate 8.

Of course, the outlet pipe 4 is located in the area below the flow equalization plate 8. Meanwhile, a plurality of flow equalizing holes 81 are formed in the flow equalizing plate 8, the diameter of each flow equalizing hole 81 is the same, the flow equalizing holes are uniformly distributed, and the flow equalizing plate is mainly used for enabling the intercepted cooling liquid to uniformly flow out of each flow equalizing hole 81 and then be discharged through the liquid outlet pipe 4. So set up, through the effect of damming of flow equalizing plate 8 and the partial pressure effect of each flow equalizing hole 81, can make the coolant liquid discharge from drain pipe 4 steadily, evenly.
In order to ensure the sealing performance of the box body 1, the top cover 9 is arranged at the top end of the box body 1. Specifically, the top cover 9 can be easily attached and detached to facilitate the attachment and detachment of the server. Meanwhile, in order to facilitate the user to observe the situation inside the box body 1 at any time, the top cover 9 is made of transparent materials, such as tempered glass.
In addition, in order to ensure the normal power supply of each server, the present embodiment is further provided with a power taking bar 10 at the bottom end of the box 1. Generally, the power taking row 10 is installed on the surface of the current equalizing plate 8 and distributed along the length direction of the installation slide rail 2.
