[0034] Embodiment 1

[0035] An immersion liquid cooling server, such as Figure 1 and Figure 2 As shown, the cooling box 1 includes a cooling box 1, a cooling medium 2, a server 3 and a heat dissipation component 4, wherein the cooling medium 2 is filled in the cooling box 1, and the cooling box 1 is a rectangular parallelepiped structure, and has a box cover 5. When the box cover 5 is tightly covered on the cooling box 1, a sealed box filled with the cooling medium 2 is formed. A first exhaust valve 6 is arranged on the box cover 5, and a drain valve 7 is arranged at the bottom of the cooling box 1, so that when the cooling medium 2 is added to the cooling box 1, the gas in the cooling medium 2 is discharged through the exhaust valve at the top, and when the cooling medium 2 in the cooling box 1 needs to be discharged, it is discharged through the drain valve 7 at the bottom.

[0036] It should be noted that the cooling medium 2 in this embodiment is a non-conductive liquid, including but not limited to fluorinated liquid and insulating oil.

[0037] Among them, a support frame is also provided at the bottom of the cooling box 1, and one or more servers 3 can be carried on the support frame to realize cooling and heat dissipation of multiple servers 3 at the same time. A liquid outlet and a liquid inlet are provided on one side of the cooling box 1, and the liquid outlet and the liquid inlet are arranged from top to bottom along the height direction of the cooling box 1. The liquid outlet is connected to the liquid outlet pipe 8, and the liquid inlet is connected to the liquid inlet pipe 9, that is, the liquid outlet pipe 8 and the liquid inlet pipe 9 are arranged up and down in a direction perpendicular to the first main pipeline 402; at the same time, the other ends of the liquid outlet pipe 8 and the liquid inlet pipe 9 are connected to the heat dissipation component 4 to realize that the cooling medium 2 enters the heat dissipation component 4 from the cooling box 1 through the liquid outlet pipe 8, and is cooled and dissipated by the heat dissipation component 4. The cooling medium 2 cooled and cooled by the heat dissipation component 4 flows back to the cooling box 1 through the liquid inlet pipe 9, and is used to cool the server 3 again.

[0038] Among them, two liquid outlets and liquid inlets are respectively arranged at the same height on the outside of the cooling box 1, and two corresponding liquid outlet pipes 8 and liquid inlet pipes 9 are also respectively arranged. The ends of the two liquid outlet pipes 8 away from the cooling box 1 are respectively connected to the two ends of the first main pipeline 402, so that the cooling medium 2 at the same horizontal height in the cooling box 1 can be simultaneously output to the first main pipeline 402 along the two liquid outlet pipes 8, and transported to the middle through the two ends of the first main pipeline 402 at the same time, so as to achieve the efficiency of transporting the cooling medium 2 to most of the heat sinks 401 through the first main pipeline 402. Similarly, the ends of the two liquid inlet pipes 9 away from the cooling box 1 are respectively connected to the two ends of the second main pipeline 403, so as to achieve the efficiency of the cooling medium 2 in the heat sink 401 flowing back to the cooling box 1.

[0039] like Figure 3 As shown, the heat dissipation component 4 in this embodiment includes a plurality of heat sinks 401, a first main pipeline 402, and a second main pipeline 403, wherein the heat sink 401 is hollow, and a plurality of heat sinks 401 are arranged at intervals along the length direction of the first main pipeline 402, the first main pipeline 402 is connected to the end of the liquid outlet pipe 8 away from the cooling box 1, the second main pipeline 403 is connected to the end of the liquid inlet pipe 9 away from the cooling box 1, the first main pipeline 402 and the second main pipeline 403 are respectively connected to the two ends of the heat sink 401, and are connected to the inside of the heat sink 401; so that the cooling medium 2 flows into the first main pipeline 402 through the liquid outlet pipe 8, and flows into the plurality of heat sinks 401 through the first main pipeline 402, and is cooled in the heat sink 401, and when the cooling medium 2 is cooled to a preset temperature, it is discharged from the heat sink 401 through the second main pipeline 403 and enters the cooling box 1.

[0040] It should be noted that, in order to achieve the regulation of the flow rate of the cooling medium 2 in the cooling box 1, a first regulating valve 10 and a first regulating pump 11 are sequentially arranged on the liquid inlet pipe 9, and the first regulating valve 10 and the first regulating pump 11 are used to regulate the flow rate of the cooling medium 2 entering the cooling box 1; at the same time, a second regulating valve 12 and a second regulating pump (not shown in the figure) are sequentially arranged on the liquid outlet pipe 8, and the second regulating valve 12 and the second regulating pump are used to regulate the flow rate of the cooling medium 2 flowing out of the cooling box 1.

[0041] In order to make the cooling box 1 applicable to various external environments, that is, in different external environments, the cooling box 1 can still be used to cool down the server 3, a liquid replenishing component 13 is arranged on the upper part of the heat dissipation component 4, and the liquid replenishing component 13 is used to accommodate the cooling medium 2 from the heat dissipation component 4 when the temperature of the cooling medium 2 in the heat dissipation component 4 exceeds the first preset threshold value; and when the temperature of the cooling medium 2 is less than the second preset threshold value, the cooling medium 2 is replenished into the heat dissipation component 4. The temperature of the cooling medium 2 in the heat dissipation component 4 is obtained by collecting the temperature of the cooling medium 2 in the first main pipeline 402.

[0042] In a specific embodiment, Figure 4 and Figure 5 As shown, the fluid infusion assembly 13 includes a connecting pipe 1301 and a receiving chamber 1302, wherein the connecting pipe 1301 is detachably connected to the first main pipeline 402 and communicates with the first main pipeline 402, and is communicated with the receiving chamber at one end of the connecting pipe 1301 away from the first main pipeline 402. An airbag 20 is arranged in the receiving chamber 1302, and the airbag 20 can be enlarged or reduced in volume according to its internal air pressure. A cooling medium 2 is stored in the receiving chamber 1302, and the cooling medium 2 is located at the bottom of the airbag 20. An exhaust channel 14 and a second exhaust valve 15 are arranged on the upper part of the receiving chamber 1302, and the exhaust channel 14 is communicated with the external air environment, wherein the exhaust pipe of the airbag 20 is passed through and placed in the exhaust channel 14, and the second exhaust valve 15 is arranged on the top surface of the receiving chamber 1302 to release the air in the cooling medium 2 in the receiving chamber 1302.

[0043] In a specific embodiment, a dehumidification device (not shown in the figure) is also connected to the exhaust pipe outlet of the airbag 20 to avoid the generation of water vapor in the airbag 20; specifically, when the temperature of the cooling medium 2 in the heat dissipation component 4 or the cooling box 1 increases, the cooling medium 2 expands due to the heat and increases in volume. At this time, the cooling medium 2 will enter the containing chamber 1302 through the connecting pipe 1301 and compress the airbag 20, so that the air in the airbag 20 is discharged through the exhaust pipe; when the temperature of the cooling medium 2 in the heat dissipation component 4 or the cooling box 1 decreases, the total volume of the cooling medium 2 shrinks, and the airbag 20 expands under the pressure of the external air to fill the containing chamber 1302. At this time, the cooling medium 2 in the containing chamber 1302 will flow back to the heat dissipation component 4 or the cooling box 1.

[0044] Since the capacity of the storage chamber 1302 is limited, in order to increase the adjustment space for the volume of the cooling medium 2 in the heat dissipation component 4 through the fluid replenishment component 13, an infusion pipeline 19 is connected to the storage chamber 1302, and the infusion pipeline 19 is connected to an external fluid supply device. At the same time, a third regulating valve 1616 is provided on the infusion pipeline 19, wherein the third regulating valve 16 is used to adjust the flow rate of the cooling medium 2 delivered by the external fluid supply device to the first main pipeline 402 through the infusion pipeline 19.

[0045] like Figure 6 As shown, the arrow direction indicates the flow direction of the cooling medium 2. When a large amount of cooling medium 2 needs to be added to the cooling box 1, the second exhaust valve 15 on the upper part of the storage chamber 1302 can be opened, and the third regulating valve 16 can be opened at the same time to input the cooling medium 2 into the storage chamber 1302 through the infusion pipeline 19. At the same time, the cooling medium 2 passes through the connecting pipe 1301 and enters the first pipeline to flow into the cooling box 1 through the liquid inlet pipe 9; after the air is exhausted, the infusion channel and the second exhaust valve 15 are closed, so that the cooling medium 2 in the storage chamber 1302 is isolated from the outside. When the excess cooling medium 2 in the cooling box 1 needs to be discharged, the storage chamber 1302 can be disassembled from the end of the connecting pipe 1301, and the second exhaust valve 15 and the third regulating valve 16 can be opened at the same time to discharge the cooling medium 2.

[0046] In order to further improve the cooling effect of the cooling medium 2 in the cooling box 1 through the heat dissipation component 4, a fan component 17 is arranged at the bottom of the heat dissipation component 4, and the outlet end of the fan component 17 faces the heat sink 401, wherein the heat sink 401 is placed in a vertical direction, and the air flow outlet in the fan component 17 is in a vertical upward direction, so that the air flow direction generated by the fan component 17 is opposite to the flow direction of the cooling medium 2 in the heat sink 401, thereby enhancing the heat dissipation effect of the fan component 17 on the cooling medium 2 in the heat sink 401.

[0047] It should be noted that the first regulating pump 11 and the second regulating pump in this embodiment can be configured as submerged pumps, and the first regulating valve 10, the second regulating valve 12 and the third regulating valve 16 can be configured as butterfly valves or ball valves.

[0048] In a specific embodiment, a power module and a sensor assembly are arranged in the cooling box 1, and the power module is used to convert 220Vac into 54Vdc or 12Vdc power supply, that is, the power module is used to supply power to the server 3, the sensor assembly and the fan assembly 17; the sensor assembly is used to detect the first temperature of the internal components of the server 3, the second temperature of the power module, the liquid inlet temperature of the cooling box 1 and the liquid outlet temperature of the cooling box 1.

[0049] It should be noted that the power supply module in this embodiment is also used to supply power to the first regulating pump 11 and the second regulating pump to realize the operation of the first regulating pump 11 and the second regulating pump.

[0050] In a specific embodiment, a connecting frame 18 is further provided at the bottom of the accommodating bin 1302, one end of the connecting frame 18 is connected to the accommodating bin 1302, and the other end is connected to the upper part of the first main pipe 402, so that the accommodating bin 1302 can be disassembled and installed on the first main pipe 402 through the first connecting frame 18, and through the setting of the connecting frame 18, the installation and disassembly of the accommodating bin 1302 can be conveniently realized, thereby improving the convenience of repairing the accommodating bin 1302 and the heat dissipation component 4.

[0051] In a specific embodiment, the immersion liquid cooling server 3 also includes a management module, which controls the opening and closing of the fan assembly 17 and adjusts the fan speed in the fan assembly 17 by obtaining the first temperature of the internal components of the server 3 detected by the sensor assembly, the second temperature of the power module, the liquid inlet temperature of the cooling box 1, and the liquid outlet temperature of the cooling box 1.

[0052] Specific implementation process: When the cooling medium 2 begins to circulate in the circulation loop formed between the cooling box 1 and the heat dissipation component 4 to cool the server 3 in the cooling box 1, the cooling medium 2 flows out through the upper liquid outlet pipe 8 and enters the first main pipeline 402, and enters the multiple heat sinks 401 along the first main pipeline 402. After being cooled by the hollow heat sink 401, the cooled cooling medium 2 enters the second main pipeline 403, and flows back to the cooling box 1 through the second main pipeline 403 and the liquid inlet pipe 9 to further cool the server 3. At the same time, when the temperature of the cooling medium 2 exceeds the first preset threshold value and the volume of the cooling medium 2 increases, the cooling medium 2 will enter the containing chamber 1302 through the connecting pipe 1301 and compress the airbag 20, so that the air in the airbag 20 is discharged through the exhaust pipe; and when the temperature of the cooling medium 2 is lower than the second preset threshold value and the volume of the cooling medium 2 decreases, the airbag 20 expands under the pressure of the external air, and the cooling medium 2 in the containing chamber 1302 will flow back to the heat dissipation component 4 or the cooling box 1.

The heat dissipation component 4 includes a plurality of heat dissipation fins 401 arranged at intervals and a fan component 17 is arranged at the bottom of the heat dissipation component 4, so that cold air can be blown into the heat dissipation fins 401 in a vertical direction through the fan component 17, thereby improving the cooling effect of the cooling medium 2 in the heat dissipation fins 401.

[0057] Furthermore, the immersion liquid cooling server 3 also includes a storage bin 1302, and the sensor assembly is also used to detect the liquid level of the cooling medium 2 in the storage bin 1302.

[0058] In this embodiment, the temperature of the cooling medium 2 in the heat dissipation component 4 is obtained. When the temperature of the cooling medium 2 in the heat dissipation component 4 exceeds a first preset threshold value and the first temperature of the internal components of the server 3 exceeds a first threshold value, the volume of the cooling medium 2 in the storage bin 1302 increases. By adjusting the third regulating valve 16 to open, part of the cooling medium 2 in the storage bin 1302 is discharged, and at the same time, the first regulating valve 10 and the first regulating pump 11 are adjusted to increase the flow rate of the cooling medium 2 into the cooling box 1, thereby improving the conduction cooling effect of the cooling medium 2.
