Description

Technical Field

[0001] The invention belongs to the technical field of cooling equipment, and in particular relates to an immersion server oil cooling system. Background Art

[0002] The server will generate a lot of heat during operation, especially core components such as CPU and GPU will generate a lot of heat under high-intensity computing. If this heat cannot be dissipated in time, the chip temperature will be too high, and then trigger the overheating protection mechanism, causing the server to automatically reduce the frequency or even shut down, seriously affecting the server performance and stability.

[0003] The traditional server cooling method is mainly air cooling, which is achieved by installing multiple fans inside the server to circulate air to reduce the temperature. These fans are usually arranged on the front and rear panels of the server, the radiator and the inside of the chassis. In addition, radiators are installed on structures that generate more heat, such as CPU radiators and GPU radiators. The radiator brings the heat to the cooling fins, and the fan blows the air to take the heat away. However, this air flow cooling method is not effective when applied to large servers. The heat dissipation efficiency is low and it cannot effectively dissipate the large amount of heat that is quickly dissipated by large servers. If the air cooling heat dissipation capacity needs to be increased, more electricity will be consumed, which will increase electricity consumption. Therefore, liquid cooling can be introduced to dissipate the heat of large servers in order to achieve better heat dissipation effects. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, an object of the present invention is to provide an immersion server oil cooling system to solve the problem of poor heat dissipation effect of traditional server air cooling.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An immersion server oil cooling system, comprising:

[0007] An installation shell, in which a server TANK is placed, and the server TANK is filled with a coolant;

[0008] A power unit, the power unit is arranged on the immersion shell and connected to the server TANK for replacing the coolant;

[0009] a plate heat exchanger connected to the power unit via a first connecting pipe;

[0010] The dry cooler is connected to the plate heat exchanger through a second connecting pipe.

[0011] Preferably, the power unit comprises an output pump and an input pump connected to the mounting shell, and the output pump and the input pump are respectively connected to the plate heat exchanger through the first connecting pipe.

[0012] Preferably, the power unit further comprises a controller connected to the mounting shell, and the controller is signal-connected to the power unit.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention fills the server TANK with coolant, and then discharges the high-temperature coolant from the server TANK through a power unit. The high-temperature coolant is cooled by a plate heat exchanger and a dry cooler to become a low-temperature coolant. The low-temperature coolant is input into the server TANK again through the power unit to absorb heat. The temperature of the server TANK is maintained within a set temperature range through the circulation of the coolant. The heat generated inside the server TANK is dissipated in the plate heat exchanger and the dry cooler. The coolant can effectively absorb the heat dissipated by the server TANK immersed therein, so the heat dissipation efficiency is higher and the energy consumption is lower.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example:

[0021] See also Figure 1 As shown, an immersion server oil cooling system includes:

[0022] An installation shell 1, in which a server TANK2 is placed, and the server TANK2 is filled with a coolant 10;

[0023] A power unit, which is arranged on the immersion shell 1 and connected to the server TANK2 for replacing the coolant 10;

[0024] The plate heat exchanger 6 is connected to the power unit via a first connecting pipe 8;

[0025] The dry cooler 7 is connected to the plate heat exchanger 6 via a second connecting pipe 9 .

[0026] As can be seen from the above, by filling the coolant 10 inside the server TANK2, and then discharging the high-temperature coolant 10 from the server TANK2 through the power unit, the high-temperature coolant 10 is cooled through the plate heat exchanger 6 and the dry cooler 7 to become the low-temperature coolant 10, and the low-temperature coolant 10 is input into the server TANK2 again through the power unit to absorb heat. The temperature of the server TANK2 is maintained within the set temperature range through the circulation of the coolant 10, and the heat generated inside the server TANK2 is dissipated in the plate heat exchanger 6 and the dry cooler 7. The coolant 10 can effectively absorb the heat dissipated by the server TANK2 immersed therein, and the heat dissipation efficiency is higher and the energy consumption is lower.

[0027] The power unit includes an output pump 3 and an input pump 4 connected to the mounting shell 1. The output pump 3 and the input pump 4 are respectively connected to the plate heat exchanger 6 through the first connecting pipe 8. The output pump 3 sucks out the high-temperature coolant 10 in the server TANK2 through the pipe, and the input pump 4 inputs the low-temperature coolant 10 into the server TANK2 through the pipe.

[0028] The power unit also includes a controller 5 connected to the mounting shell 1, and the controller 5 is signal-connected to the power unit. The user can set an operating program inside the controller 5 to control the start-up time and start-up frequency of the power unit to maintain the environmental dimensions of the server TANK2 within an appropriate range.

[0029] A pressure sensor and a temperature sensor are provided in the connecting pipe between the power unit and the server TANK2, and the pressure sensor and the temperature sensor are respectively connected to the controller 5 by signal. The pressure sensor and the temperature sensor can obtain the pressure data and temperature data inside the connecting pipe of the server TANK2 in real time, so as to judge the environmental conditions inside the server TANK2. When the temperature inside the server TANK2 is relatively high and continues to rise, the controller 5 receives the signal from the temperature sensor, and increases the flow rate of the output pump 3 and the input pump 4, increases the circulation speed of the coolant inside the server TANK2, and thereby reduces the internal temperature of the server TANK2. The flow rates of the output pump 3 and the input pump 4 can also be adjusted according to the pressure data inside the server TANK2, so that the internal pressure of the server TANK2 is maintained in a suitable range.

[0030] The coolant 10 comprises synthetic acetylene, antioxidant, heat stabilizer and fluidity regulator, is colorless, clear and transparent, has a chromaticity of less than 0.5, a pour point of less than -60°C, and a density of 796.4 kg / m at 20°C. 3 , flash point 164℃, initial boiling point greater than 300℃, decomposition temperature greater than 350℃, insoluble in water, soluble in organic solvents, kinematic viscosity at 40℃ is 5,2mm 2 / s, non-explosive, non-oxidizing.

[0031] When in use, the heat emitted by the internal structure of the server TANK2 will be absorbed by the coolant 10. After the controller 10 detects the rise in the internal temperature of the server TANK2 through the temperature sensor, it controls the output pump 3 and the input pump 4 to start. The output pump 3 pumps the high-temperature coolant 3 out of the server TANK2 and pumps it into the plate heat exchanger 6 through the first connecting pipe 8, and then dissipates the heat for the first time. The coolant 10 after the first heat dissipation of the plate heat exchanger 6 enters the dry cooler 7 for cooling to form a low-temperature coolant 10. The input pump 4 draws the low-temperature coolant 10 through the first connecting pipe 8, the plate heat exchanger 6 and the second connecting pipe 9 in turn, and the low-temperature coolant 10 enters the server The high-temperature coolant 10 is replaced in the server TANK2, and the heat emitted by the server TANK2 is repeatedly circulated to absorb. If the internal temperature of the server TANK2 rises quickly, the flow rates of the output pump 3 and the input pump 4 are increased to speed up the circulation rate of the coolant 10. If the internal pressure of the server TANK2 increases, in addition to increasing the circulation rate, the flow rate of the output pump 3 can be increased or the flow rate of the input pump 4 can be reduced to reduce the internal pressure of the server TANK2. Conversely, if the internal pressure of the server TANK2 decreases, the flow rate of the output pump 3 can be reduced or the flow rate of the input pump 4 can be increased to increase the internal pressure of the server TANK2.
