Description

Technical Field

[0001] This utility model relates to the field of data center heat dissipation devices, and in particular to an immersion liquid cooling system and communication equipment room equipment. Background Technology

[0002] Immersion liquid cooling technology is one of the main technical approaches to address the high power density and low PUE (Power Usage Effectiveness) requirements of future data centers. While immersion liquid cooling provides efficient heat dissipation, it also brings a series of design requirements, such as ensuring high system reliability, redundancy and safety, non-stop maintenance, ease of equipment installation and maintenance, and low environmental noise.

[0003] Most existing immersion liquid cooling applications are single-unit systems, meaning there is only one tank (immersion enclosure) paired with one or two CDUs (Cooling Distribution Units). Such systems lead to significant increases in cost and floor space when deployed on a large scale. A few systems are systems with one or two CDUs supporting multiple tanks, i.e., centralized CDU systems. Although such systems reduce equipment costs, they also cause problems such as increased size of plate heat exchangers and pumps, as well as significantly increased pump power consumption and noise, because the CDUs have to supply cooling to multiple tanks.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

Therefore, the directional terms used are for explanation and understanding of this invention, and not for limiting it. Furthermore, in the accompanying drawings, structures that are similar or identical are indicated by the same reference numerals.

[0027] Reference Figures 1 to 6 This utility model provides an immersion liquid cooling system. The structure and working principle of this immersion liquid cooling system will be described in detail below with reference to the accompanying drawings. Figure 1 As shown, the immersion liquid cooling system includes: a refrigeration unit 40 connected to a first ring pipe 11 and a second ring pipe 12, wherein the refrigeration unit 40 outputs low-temperature coolant through the first ring pipe 11 and recovers high-temperature coolant through the second ring pipe 12; a liquid cooling tank 20, wherein there are multiple liquid cooling tanks 20; and a cooling capacity distribution unit 30, wherein a plurality of cooling capacity distribution units 30 are cyclically and alternately connected to a plurality of liquid cooling tanks 20 to form a ring circuit, and each cooling capacity distribution unit 30 is connected to the first ring pipe 11 and the second ring pipe 12.

[0028] In practice, the immersion liquid cooling system can be applied to communication equipment in data center computer rooms to dissipate heat from servers and other communication devices. The immersion liquid cooling system mainly includes a cooling unit 40, a liquid cooling box 20, and a cooling capacity distribution unit 30. The cooling unit 40 can be a dry cooler or other device used to achieve cooling. The cooling unit 40 is connected to a first ring pipe 11 and a second ring pipe 12. Both ends of the first ring pipe 11 and the second ring pipe 12 are connected to the cooling unit 40 to form a ring circuit. The refrigeration unit 40 outputs low-temperature coolant through the first loop pipe 11 and recovers high-temperature coolant through the second loop pipe 12. Specifically, after recovering the high-temperature coolant through the second loop pipe 12, the refrigeration unit 40 cools the high-temperature coolant, converting it into low-temperature coolant, which is then output to the cooling capacity distribution unit 30 through the first loop pipe 11. The cooling capacity distribution unit 30 is responsible for distributing the low-temperature coolant to the liquid cooling tank 20. The liquid cooling tank 20 is used to house IT equipment such as servers and switches that require heat dissipation. The low-temperature coolant entering the liquid cooling tank 20 can completely immerse the equipment inside, and heat dissipation is achieved through heat exchange between the coolant and the equipment in the liquid cooling tank 20. Multiple cooling capacity distribution units 30 and liquid cooling tanks 20 are provided, and the specific number is not limited. Several cooling capacity distribution units 30 and several liquid cooling tanks 20 are cyclically and alternately connected to form a loop. Specifically, the number of cooling distribution units 30 corresponds to the number of liquid cooling boxes 20. The specific number of cooling distribution units 30 and liquid cooling boxes 20 can be set according to the actual number and scale of equipment that needs heat dissipation. Each pair of liquid cooling boxes 20 is connected by a cooling distribution unit 30, and they alternate in sequence to form a ring circuit. Each cooling distribution unit 30 is connected to the first ring pipe 11 and the second ring pipe 12. In practical applications, the refrigeration unit 40 outputs low-temperature coolant through the first loop pipe 11. The low-temperature coolant circulates in the first loop pipe 11 and is evenly distributed to each cooling capacity distribution unit 30. The cooling capacity distribution unit 30 distributes cooling to the liquid cooling tank 20. Each cooling capacity distribution unit 30 can simultaneously supply cooling to two liquid cooling tanks 20. The low-temperature coolant enters the liquid cooling tank 20, immersing the equipment inside and exchanging heat with the equipment, thus lowering the equipment temperature. After completing the heat exchange, the coolant temperature rises, becoming a high-temperature coolant. The high-temperature coolant then enters the second loop pipe 12 through the cooling capacity distribution unit 30 for circulation and is recovered by the refrigeration unit 40. The refrigeration unit 40 cools and lowers the temperature of the high-temperature coolant to regenerate the low-temperature coolant, which then re-enters the first loop pipe 11 for circulation, thereby achieving the purpose of circulating cooling of the equipment.In practical applications, even if one of the cooling distribution units 30 in the system fails, it will not affect the cooling supply of other normal cooling distribution units 30. Compared with traditional liquid cooling systems, the immersion liquid cooling system of this application not only has higher heat dissipation efficiency and better reliability, but also allows the cooling distribution unit 30 to be designed to be smaller and quieter under the same heat dissipation scale, and the equipment is easier to install and maintain.

[0029] In one embodiment, reference is made to Figure 2 and Figure 3 The cooling capacity distribution unit 30 is provided with a first liquid inlet 2, a second liquid inlet 3, a first liquid outlet 1, and a second liquid outlet 4. The liquid cooling box 20 is provided with a third liquid inlet 6, a fourth liquid inlet 8, a third liquid outlet 5, and a fourth liquid outlet 7. The first liquid inlet 2 and the second liquid inlet 3 are respectively connected to the fourth liquid outlet 7 and the third liquid outlet 5, respectively. The first liquid outlet 1 and the second liquid outlet 4 are respectively connected to the fourth liquid inlet 8 and the third liquid inlet 6, respectively. In specific implementation, each cooling capacity distribution unit 30 is provided with at least four ports: a first liquid inlet 2, a second liquid inlet 3, a first liquid outlet 1, and a second liquid outlet 4. Each liquid cooling box 20 is provided with four ports: a third liquid inlet 6, a fourth liquid inlet 8, a third liquid outlet 5, and a fourth liquid outlet 7. The first liquid inlet 2 and the second liquid inlet 3 of the cooling capacity distribution unit 30 are respectively connected to the fourth liquid outlet 7 and the third liquid outlet 5 of the liquid cooling box 20 through pipes. The first liquid outlet 1 and the second liquid outlet 4 of the cooling capacity distribution unit 30 are respectively connected to the fourth liquid inlet 8 and the third liquid inlet 6 of the liquid cooling box 20 through pipes. In practical applications, the low-temperature coolant circulating in the first loop pipe 11 enters each cooling distribution unit 30, where it undergoes heat exchange and distribution. The low-temperature coolant is output through the first outlet 1 and the second outlet of the cooling distribution unit 30, and enters one of the liquid cooling tanks 20 through the third inlet 6, and another through the fourth inlet 8, simultaneously supplying cooling to both liquid cooling tanks 20. The low-temperature coolant exchanges heat with the equipment in the liquid cooling tanks 20, thus becoming a high-temperature coolant. The high-temperature coolant is output through the third outlet 5 and the fourth outlet 7 of the liquid cooling tank 20, returning to the cooling distribution unit 30. It then returns to the cooling distribution unit 30 through the first outlet 1 and the second outlet 4, and then returns to the second loop pipe 12 for circulation and enters the refrigeration unit 40 for re-cooling, thereby completing the entire liquid cooling cycle and achieving efficient heat dissipation for the equipment in the liquid cooling tanks 20.

[0030] In a further embodiment, refer to Figure 4The cooling capacity distribution unit 30 is further provided with a fifth inlet 10 and a fifth outlet 9. The fifth inlet 10 is connected to the first ring pipe 11, and the fifth outlet 9 is connected to the second ring pipe 12. In specific implementation, each cooling capacity distribution unit 30 is provided with a fifth inlet 10 and a fifth outlet 9. The cooling capacity distribution unit 30 is connected to the first ring pipe 11 through the fifth inlet 10 and to the second ring pipe 12 through the fifth outlet 9. In practical application, the low-temperature coolant circulating in the first ring pipe 11 enters each cooling capacity distribution unit 30 through the fifth inlet 10, and the high-temperature coolant returning to each cooling capacity distribution unit 30 enters the second ring pipe 12 through the fifth outlet 9, thus realizing the circulation of coolant.

[0031] In a further embodiment, refer to Figure 5 The cooling capacity distribution unit 30 includes a plate heat exchanger 31, a pump body 32, and several first manual valves 34. The plate heat exchanger 31 is connected to the inlet of the pump body 32. The first liquid inlet 2 and the second liquid inlet 3 are each connected to the plate heat exchanger 31 through a first manual valve 34. The first liquid outlet 1 and the second liquid outlet 4 are each connected to the outlet of the pump body 32 through a first manual valve 34. The fifth liquid inlet 10 and the fifth liquid outlet 9 are each connected to the plate heat exchanger 31 through a first manual valve 34. In specific implementation, each cooling capacity distribution unit 30 includes a plate heat exchanger 31, a pump body 32, and several first manual valves 34. The plate heat exchanger 31 is usually composed of heat exchange channels made up of several metal plates, which can realize the heat exchange between the coolant and the external heat source. The pump body 32 is mainly used to provide power for the flow and circulation of the coolant. The first manual valve 34 is a valve structure that can be manually controlled to open and close, specifically a ball valve. Inside the cooling capacity distribution unit 30, a plate heat exchanger 31 is connected to the inlet of the pump body 32. The first liquid inlet 2 and the second liquid inlet 3 are each connected to the plate heat exchanger 31 via a first manual valve 34. The first liquid outlet 1 and the second liquid outlet 4 are each connected to the outlet of the pump body 32 via a first manual valve 34. The fifth liquid inlet 10 and the fifth liquid outlet 9 are also each connected to the plate heat exchanger 31 via a first manual valve 34. The first manual valves 34 allow for manual control of both the input and output of the coolant, facilitating maintenance and replacement in case of a malfunction in the cooling capacity distribution unit 30 without affecting the continuous operation of the liquid cooling system.

[0032] In a further embodiment, refer to Figure 5The cooling capacity distribution unit 30 also includes a one-way valve 33. The inlet of the one-way valve 33 is connected to the outlet of the pump body 32, and the first liquid outlet 1 and the second liquid outlet 4 are connected to the outlet of the one-way valve 33 through the first manual valve 34. In specific implementations, each cooling capacity distribution unit 30 also includes a one-way valve 33, which is a unidirectional valve body structure with the flow direction from the inlet end to the outlet end. Inside each cooling capacity distribution unit 30, the inlet of the one-way valve 33 is connected to the outlet of the pump body 32, and the first liquid outlet 1 and the second liquid outlet 4 are connected to the outlet of the one-way valve 33 through the first manual valve 34. In practical applications, the one-way valve 33 can ensure that the coolant does not flow back into the pump body 32 and damage the pump body 32, thus improving the stability of the system.

[0033] In a further embodiment, refer to Figure 5 The plate heat exchanger 31 has two inlets and two outlets. The first inlet 2 and the second inlet 3 are connected to one inlet of the plate heat exchanger 31 through the first manual valve 34. The fifth inlet 10 is connected to the other inlet of the plate heat exchanger 31 through the first manual valve 34. One outlet of the plate heat exchanger 31 is connected to the inlet of the pump body 32. The fifth outlet 9 is connected to the other outlet of the plate heat exchanger 31 through the first manual valve 34. In specific implementation, each cooling capacity distribution unit 30 has two inlets and two outlets in its plate heat exchanger 31. Inside each cooling capacity distribution unit 30, the first liquid inlet 2 and the second liquid inlet 3 are connected to one of the inlets of the plate heat exchanger 31 through the first manual valve 34. The fifth liquid inlet 10 is connected to the other inlet of the plate heat exchanger 31 through the first manual valve 34. One outlet of the plate heat exchanger 31 is connected to the inlet of the pump body 32. The fifth liquid outlet 9 is connected to the other outlet of the plate heat exchanger 31 through the first manual valve 34. Through the cooperation of the two inlets and two outlets of the plate heat exchanger 31, the distribution of coolant is realized.

[0034] In one embodiment, reference is made to Figure 6The liquid cooling tank 20 includes a tank body 24 and a flow equalization plate 21. The flow equalization plate 21 is located at the bottom of the tank body 24. The third liquid inlet 6 and the fourth liquid inlet 8 are connected to the flow equalization plate 21. The flow equalization plate 21 is used to inject low-temperature coolant into the tank body 24 from different positions at the bottom of the tank body 24 at the same flow rate. In specific implementations, each liquid cooling tank 20 includes a tank body 24 and a flow equalization plate 21. The tank body 24 is a structure that houses various equipment, and the coolant immerses the equipment within the tank body 24. A flow equalization plate 21 is located at the bottom of the housing 24. The third liquid inlet 6 and the fourth liquid inlet 8 of the liquid cooling tank 20 are both connected to the inlet of the flow equalization plate 21. The flow equalization plate 21 is used to inject low-temperature coolant into the housing 24 from different positions at the bottom of the housing 24 at the same flow rate. Specifically, the flow equalization plate 21 has one liquid inlet and several liquid outlets, each of which is connected to the liquid inlet. The third liquid inlet 6 and the fourth liquid inlet 8 are both connected to the liquid inlet of the flow equalization plate 21. The flow equalization plate 21 is arranged at the bottom of the housing 24, so that the liquid outlets on the flow equalization plate 21 are distributed... The coolant is distributed at the bottom of the housing 24. Due to the different distances between the outlet and inlet at different locations, the liquid pressure is different, and the diameter of the outlet at different locations on the flow equalization plate 21 is also different. This is to ensure that the outflow rate of each outlet is the same. After the low-temperature coolant enters the flow equalization plate 21, it is output through the outlet on the flow equalization plate 21. Since the flow equalization plate 21 is arranged at the bottom of the housing 24, the coolant output from the outlet on the flow equalization plate 21 will be evenly injected into the housing 24 from different locations at the bottom of the housing 24 to ensure the uniformity of the coolant entering the housing 24.

[0035] In a further embodiment, refer to Figure 6 The liquid cooling box 20 also includes a buffer pool 22, which is formed in the box body 24. The third liquid outlet 5 and the fourth liquid outlet 7 are connected to the buffer pool 22. In specific implementation, the liquid cooling box 20 also includes a buffer pool 22, which is formed in the box body 24. Specifically, the buffer pool 22 is an independent space in the box body 24, with an open design, and is connected to the air pressure inside the box body 24. The third liquid outlet 5 and the fourth liquid outlet 7 of the liquid cooling box 20 are both connected to the buffer pool 22. The coolant in the box body 24 must pass through the buffer pool 22 before it can be discharged from the box body 24 through the third liquid outlet 5 and the fourth liquid outlet 7 and enter the cooling capacity distribution unit 30. The setting of the buffer pool 22 can prevent the cooling capacity distribution unit 30 from directly drawing the coolant in the box body 24, and prevent the low temperature coolant from being discharged directly from the box body 24 before it has had time to exchange heat with the equipment in the box body 24. This can improve the heat exchange efficiency and also prevent the third liquid outlet 5 and the fourth liquid outlet 7 from interfering with each other. Even if the liquid flow rates of the third liquid outlet 5 and the fourth liquid outlet 7 are different, it will not affect the heat dissipation of the system.

[0036] In a further embodiment, refer to Figure 6The liquid cooling tank 20 also includes multiple second manual valves 23. The third inlet 6 and the fourth inlet 8 are each connected to the flow equalization plate 21 via a second manual valve 23, and the third outlet 5 and the fourth outlet 7 are each connected to the buffer tank 22 via a second manual valve 23. In specific implementations, each liquid cooling tank 20 also includes multiple second manual valves 23. Each second manual valve 23 is a valve body structure that can be manually controlled to open and close, specifically a ball valve. Inside the liquid cooling tank 20, the third inlet 6 and the fourth inlet 8 are each connected to the inlet of the flow equalization plate 21 via a second manual valve 23, and the third outlet 5 and the fourth outlet 7 are each connected to the buffer tank 22 via a second manual valve 23. Through the setting of the second manual valves 23, the input and output of the coolant can be manually controlled, facilitating maintenance and replacement in case of a malfunction in the liquid cooling tank 20 without affecting the continuous operation of the liquid cooling system.

[0037] In summary, compared with traditional liquid cooling systems, the immersion liquid cooling system provided by this utility model not only has higher heat dissipation efficiency, but also allows for a smaller cooling capacity distribution unit with lower noise, lower deployment cost, and easier installation and maintenance under the same heat dissipation scale.

[0038] This utility model also provides a communication equipment room device, which is equipped with the immersion liquid cooling system described in the above embodiments. The immersion liquid cooling system can be integrated with the communication equipment room device, which can be used to house various IT equipment such as servers and switches. The immersion liquid cooling system can dissipate heat from the various IT equipment in the cabinet, thereby improving equipment operating efficiency. Since the specific structure and working principle of the immersion liquid cooling system have been described in detail in the preceding description, they will not be repeated here for the sake of brevity.

[0039] The communication equipment room equipment in this embodiment, by adopting the immersion liquid cooling system provided by this utility model embodiment, can efficiently dissipate heat from IT equipment, improve the operating efficiency of the equipment, and make installation and maintenance more convenient.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
