Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation equipment, and particularly to an immersion liquid-cooled cabinet, a liquid-cooling control method and an overhaul method. Background Art

[0002] Refer to Figure 1 , a liquid-cooled cabinet has been developed, which includes a cabinet main body 1 and a refrigeration system 2. Among them, the cabinet main body 1 includes a main chamber 101 and an auxiliary chamber 102 that are interconnected. Servers can be placed in the main chamber 101, and the evaporator 204 of the refrigeration system 2 is placed in the auxiliary chamber 102. The cooling oil circulates between the main chamber 101 and the auxiliary chamber 102.

[0003] Specifically, when the server is working, it will release a large amount of heat, causing the temperature of the cooling oil in the main chamber 101 to rise. When the cooling oil flows to the auxiliary chamber 102, it absorbs the cold released by the evaporator 204 and the temperature drops, and then flows back into the main chamber 101 again to absorb heat for the server to cool down. This process repeats, thereby continuously cooling the server.

[0004] The problems of the existing liquid-cooled cabinet are as follows:

[0005] When the server needs to be taken out of the cabinet main body 1, it is necessary to first drain the cooling oil in the main chamber 101. However, in order to achieve the circulation of the cooling oil, both the main chamber 101 and the auxiliary chamber 102 are filled with cooling oil. Therefore, the cooling oil in the main chamber 101 cannot be directly transferred to the auxiliary chamber 102, and only the cooling oil in the main chamber 101 can be drained. After the server is put back into the main chamber 101, new cooling oil needs to be poured into the main chamber 101 again, resulting in serious waste.

[0006] Therefore, it is necessary to improve the existing liquid-cooled cabinet to solve the problem of wasting a large amount of cooling oil when taking in and out the server.

[0007] The above information disclosed in this background section is only included to enhance the understanding of the background of the present disclosure, and thus may include information that does not form the prior art known to those of ordinary skill in the art at present. Summary of the Invention

However, these implementation manners do not limit the present invention, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these implementation manners is included in the protection scope of the present invention.

[0060] The present invention provides an immersive liquid-cooled cabinet, and also provides a liquid-cooling temperature control method executed by the immersive liquid-cooled cabinet, and provides an overhaul method executed by the immersive liquid-cooled cabinet. It should be noted that the server can be placed in the immersive liquid-cooled cabinet of the present invention, so that the immersive liquid-cooled cabinet is applied to the application scenario of liquid-cooling the server, or other electronic devices or mechanical devices and other heat-generating devices can be placed in the immersive liquid-cooled cabinet, so that the immersive liquid-cooled cabinet is applied to the application scenario of liquid-cooling other heat-generating devices. The present invention does not make any limitation in this regard. For the convenience of understanding, the following takes the immersive liquid-cooled cabinet applied to liquid-cooling the server as an example to introduce the immersive liquid-cooled cabinet and its working principle.

[0061] Embodiment 1

[0062] This embodiment mainly introduces the specific structure of the immersive liquid-cooled cabinet.

[0063] See Figure 2 , the immersion liquid cooling cabinet includes a cabinet body 1 and a refrigeration system 2. The cabinet body 1 includes a main chamber 101 for storing servers and at least two auxiliary chambers 102 communicating with the main chamber 101; wherein, part of the auxiliary chambers 102 serve as circulation chambers 102a, and cooling oil circulates between the circulation chambers 102a and the main chamber 101; part of the auxiliary chambers 102 serve as temporary storage chambers 102b for temporarily storing the cooling oil in the main chamber 101. The refrigeration system 2 is used to provide cooling capacity to the cooling oil in the circulation chamber 102a.

[0064] It should be noted that, generally, servers are placed in the main chamber 101. The main chamber 101 and the auxiliary chambers 102 serving as circulation chambers 102a are both filled with cooling oil, and the temporary storage chamber 102b is empty. The temporary storage chamber 102b has sufficient space to hold the cooling oil in the main chamber 101. At this time, the cooling oil absorbs heat in the circulation chamber 102a and then enters the main chamber 101 to cool the servers; when the servers need to be taken out of the main chamber 101, the flow of the cooling oil between the circulation chamber 102a and the main chamber 101 is interrupted, so that the cooling oil in the circulation chamber 102a remains in the circulation chamber 102a, and then the cooling oil in the main chamber 101 is transferred to the temporary storage chamber 102b, thereby emptying the cooling oil in the main chamber 101 to facilitate the removal of the servers. After the servers are put back into the main chamber 101, the cooling oil in the temporary storage chamber 102b is sent back to the main chamber 101, and then the cooling oil is circulated between the circulation chamber 102a and the main chamber 101 again, and the heat dissipation and cooling of the servers can continue. Therefore, the immersion liquid cooling cabinet provided in this embodiment can realize the reuse of the cooling oil when taking in and out the servers, effectively solving the problem that a large amount of cooling oil is wasted when taking in and out the servers in the existing liquid cooling cabinets.

[0065] Optionally, the number of the refrigeration systems 2 is the same as the number of the auxiliary chambers 102, and each auxiliary chamber 102 is correspondingly configured with one refrigeration system 2. Such a setting can make each auxiliary chamber 102 serve as a circulation chamber 102a, and each circulation chamber 102a can be switched to a temporary storage chamber 102b when necessary.

[0066] In this embodiment, the refrigeration system 2 includes a compressor 201, a condenser 202, a throttling device 203, and an evaporator 204 connected in sequence; wherein, the compressor 201, the condenser 202, and the throttling device 203 are all located outside the cabinet body 1; the evaporator 204 is located in the corresponding auxiliary chamber 102.

[0067] In this embodiment, the immersive liquid-cooled cabinet further includes at least two liquid inlet assemblies 3 and at least two liquid drain assemblies 4. Among them, each of the auxiliary chambers 102 is correspondingly configured with one of the liquid inlet assemblies 3; the liquid inlet assembly 3 communicates with the auxiliary chamber 102 and the main chamber 101, and is used to convey the cooling oil in the auxiliary chamber 102 to the corresponding main chamber 101. Each of the auxiliary chambers 102 is correspondingly configured with one of the liquid drain assemblies 4; the liquid drain assembly 4 communicates with the main chamber 101 and the auxiliary chamber 102, and is used to convey the cooling oil in the main chamber 101 to the corresponding auxiliary chamber 102.

[0068] Further, both the liquid inlet assembly 3 and the liquid drain assembly 4 are connected to the bottom of the main chamber 101 and the bottom of the auxiliary chamber 102, so as to prevent the transfer of the cooling oil from being unable to be realized when the liquid level of the cooling oil in the main chamber 101 or the auxiliary chamber 102 is too low.

[0069] Specifically, both the liquid inlet assembly 3 and the liquid drain assembly 4 include pipelines, stop valves and liquid pumps. By opening the stop valve and the liquid pump, the cooling oil can be driven to flow; by closing the stop valve and the liquid pump, the flow of the cooling oil can be blocked.

[0070] The detailed working process of the immersive liquid-cooled cabinet provided in this embodiment is as follows:

[0071] (1) Before taking out the server from the main chamber 101:

[0072] ① First, close the liquid inlet assembly 3 between the circulation chamber 102a and the main chamber 101, and close the liquid inlet assembly 3 between the temporary storage chamber 102b and the main chamber 101;

[0073] ② Only open the liquid drain assembly 4 between the temporary storage chamber 102b and the main chamber 101. After all the cooling oil in the main chamber 101 is transferred to the temporary storage chamber 102b through the liquid drain assembly 4 between the temporary storage chamber 102b and the main chamber 101, then close the liquid drain assembly 4 between the temporary storage chamber 102b and the main chamber 101;

[0074] ③ At this time, most of the cooling oil is stored in the circulation chamber 102a and the temporary storage chamber 102b. The liquid level of the cooling oil in the main chamber 101 is relatively low. Even if the main chamber 101 is opened, the cooling oil will not overflow. Therefore, the main chamber 101 can be directly opened to take out the server.

[0075] (2) After putting the server into the main chamber 101:

[0076] ① First, open the liquid inlet component 3 between the temporary storage chamber 102b and the main chamber 101 (other liquid inlet components 3 and the liquid discharge component 4 remain closed). After the liquid inlet component 3 between the temporary storage chamber 102b and the main chamber 101 sends the cooling oil in the temporary storage chamber 102b back to the main chamber 101, close the liquid inlet component 3 between the temporary storage chamber 102b and the main chamber 101;

[0077] ② Then, open the liquid inlet component 3 between the circulation chamber 102a and the main chamber 101. The refrigeration system 2 corresponding to the circulation chamber 102a will provide cooling capacity to the cooling oil in the circulation chamber 102a, causing the temperature of the cooling oil in the circulation chamber 102a to drop;

[0078] ③ Next, the liquid inlet component 3 connected to the circulation chamber 102a sends the cooled cooling oil in the circulation chamber 102a into the main chamber 101. The cooling oil in the main chamber 101 directly immerses the server. After absorbing the heat released by the server, the temperature rises. The liquid discharge component 4 connected to the circulation chamber 102a sends the heated cooling oil in the main chamber 101 back to the auxiliary chamber 102, where it is re-cooled by the refrigeration system 2, realizing the circulating flow of the cooling oil between the circulation chamber 102a and the main chamber 101, and thus realizing the continuous liquid cooling heat dissipation operation of the server.

[0079] In this embodiment, the number of the auxiliary chambers 102 is two, which are respectively located on the left and right sides of the main chamber 101. Generally, the left auxiliary chamber 102 can be used as the circulation chamber 102a, and the right auxiliary chamber 102 can be used as the temporary storage chamber 102b. When necessary, the right auxiliary chamber 102 can be used as the circulation chamber 102a, and the left auxiliary chamber 102 can be used as the temporary storage chamber 102b.

[0080] Of course, in some other embodiments, the number of the auxiliary chambers 102 can be three, which are respectively arranged on the left, right, and back of the main chamber 101. One is used as the circulation chamber 102a and two are used as the temporary storage chambers 102b, or two are used as the circulation chambers 102a and one is used as the temporary storage chamber 102b; or the number of the auxiliary chambers 102 can be four, which are respectively arranged on the left, right, back, and top of the main chamber 101, etc. One is used as the circulation chamber 102a and three are used as the temporary storage chambers 102b, or two are used as the circulation chambers 102a and two are used as the temporary storage chambers 102b, or three are used as the circulation chambers 102a and one is used as the temporary storage chamber 102b. This embodiment does not limit the upper limit of the number of the auxiliary chambers 102 and their specific positions.

[0081] In this embodiment, a main liquid level sensor 6 is provided in the main chamber 101 to obtain the actual liquid level of the cooling oil in the main chamber 101; a main temperature sensor 5 is also provided in the main chamber 101 to obtain the main actual liquid temperature of the cooling oil in the main chamber 101. A sub-temperature sensor 7 is provided in the sub-chamber 102 to obtain the sub-actual liquid temperature of the cooling oil in the sub-chamber 102.

[0082] In this embodiment, the main liquid level sensor 6 may include a floating ball liquid level switch fixed to the upper part of the main chamber 101 (when the liquid level reaches this floating ball liquid level switch, it is considered that the liquid level reaches the preset upper limit liquid level of the main chamber 101, and the replenishment of the cooling oil to the main chamber 101 should be stopped) and a floating ball liquid level switch fixed to the lower part of the main chamber 101 (when the liquid level is lower than this floating ball liquid level switch, it is considered that the liquid level reaches the preset lower limit liquid level of the main chamber 101, and the replenishment of the cooling oil to the main chamber 101 should be started). Alternatively, the main liquid level sensor 6 may be a differential pressure liquid level sensor installed at the lower part of the main chamber 101. The actual liquid level height in the main chamber 101 is calculated according to the hydraulic pressure sensed by the differential pressure liquid level sensor, and then it is evaluated whether the current liquid level is between the preset upper limit liquid level and the preset lower limit liquid level. Otherwise, operations such as stopping liquid filling or starting liquid filling are carried out accordingly. Of course, there are many types of liquid level switches on the market that can realize the liquid level detection of the main chamber 101, and then judge whether the actual liquid level in the main chamber 101 is between the preset upper limit liquid level and the preset lower limit liquid level. This is not the focus of the present invention, so it will not be elaborated.

[0083] Optionally, the main temperature sensor 5 is located below the main liquid level sensor 6 to ensure that even when the liquid level in the main chamber 101 is low, the main temperature sensor 5 can still obtain the temperature of the cooling oil in the main chamber 101.

[0084] Optionally, a transfer chamber 103 is provided at the bottom of the main chamber 101, and the main chamber 101 and the sub-chamber 102 are connected through the transfer chamber 103.

[0085] The immersion liquid cooling cabinet provided in this embodiment has the following advantages:

[0086] ① When taking out and putting in the server, the cooling oil in the main chamber 101 can be temporarily stored in the temporary storage chamber 102b, and after taking out and putting in the server, the cooling oil in the temporary storage chamber 102b can be reused, effectively solving the problem of serious waste caused by pouring out the cooling oil when taking out and putting in the server in the existing liquid cooling system;

[0087] ② The circulation chamber 102a and the temporary storage chamber 102b can be switched with each other to improve the flexibility of the temporary storage of the cooling oil.

[0088] Embodiment 2

[0089] This embodiment provides a liquid cooling temperature control method, which is executed by the immersion liquid cooling cabinet described in Embodiment 1 and has the same functions and beneficial effects.

[0090] See Figure 2 and Figure 3 , the liquid cooling temperature control method includes:

[0091] S201: Obtain the main actual liquid temperature of the cooling oil in the main chamber 101 and the secondary actual liquid temperature of the cooling oil in the circulation chamber 102a;

[0092] S202: Control the working states of the circulation chamber 102a and the refrigeration system 2 according to the main actual liquid temperature and the secondary actual liquid temperature.

[0093] Further, step S202 can be refined to include:

[0094] S2021: Specify a preset circulation temperature and a preset refrigeration temperature;

[0095] Specifically, through experiments, the preset circulation temperature and the preset refrigeration temperature can be directly defined before the immersion liquid cooling cabinet leaves the factory, or the preset circulation temperature and the preset refrigeration temperature can be dynamically updated and optimized through big data.

[0096] S2022:

[0097] If the main actual liquid temperature < the preset circulation temperature, it means that the temperature of the cooling oil in the main chamber 101 is relatively low at this time, the server is not started or the heat generation is relatively low, and there is no need for circulating heat dissipation. Therefore, the circulating flow of the cooling oil between the main chamber 101 and the circulation chamber 102a can be interrupted;

[0098] If the following conditions are simultaneously met: the secondary actual liquid temperature < the main actual liquid temperature, the secondary actual liquid temperature < the preset refrigeration temperature, and the main actual liquid temperature > the preset circulation temperature, it means that although the temperature of the cooling oil in the main chamber 101 is relatively high, it has not reached the level where the refrigeration system 2 must be used. At this time, for energy conservation, the refrigeration system 2 can be turned off, and the cooling oil circulation between the main chamber 101 and the circulation chamber 102a can be made to flow, and the server can be cooled solely by the circulating flow of the cooling oil. The main power consumption is the power consumption of the liquid pump;

[0099] If the following conditions are simultaneously met: the secondary actual liquid temperature < the main actual liquid temperature, the secondary actual liquid temperature ≥ the preset refrigeration temperature, and the main actual liquid temperature > the preset circulation temperature, it means that the temperature of the cooling oil in the main chamber 101 is already relatively high and has reached the level where the refrigeration system 2 must be used. The refrigeration system 2 can be turned on, and the cooling oil circulation between the main chamber 101 and the circulation chamber 102a can be made to flow.

[0100] The liquid cooling temperature control method provided in this embodiment plans several heat dissipation solutions according to the temperature of the cooling oil in the main chamber 101. When the temperature of the cooling oil in the main chamber 101 is relatively low, the refrigeration system 2 is not enabled. When the temperature of the cooling oil in the main chamber 101 is relatively high, the refrigeration system 2 is enabled, which helps to reduce the overall power consumption of the immersion liquid cooling cabinet under comprehensive working conditions.

[0101] Embodiment 3

[0102] This embodiment provides an overhaul method, which is executed by the immersion liquid cooling cabinet described in Embodiment 1 and has the same functions and beneficial effects.

[0103] See Figure 2 and Figure 4 , the overhaul method includes:

[0104] S301: Close the liquid inlet component 3 and the liquid discharge component 4 between the main chamber 101 and the circulation chamber 102a, thereby interrupting the circulating flow of the cooling oil between the main chamber 101 and the circulation chamber 102a;

[0105] S302: Close the liquid inlet component 3 between the main chamber 101 and the temporary storage chamber 102b, open the liquid discharge component 4 between the main chamber 101 and the temporary storage chamber 102b, and thereby transfer the cooling oil in the main chamber 101 to the temporary storage chamber 102b;

[0106] S303: Overhaul the server or the main chamber 101;

[0107] S304: Designate at least one of the auxiliary chambers 102 as the circulation chamber 102a and designate at least one of the auxiliary chambers 102 as the temporary storage chamber 102b;

[0108] It can be understood that after step S302 is completed, the original circulation chamber 102a and the temporary storage chamber 102b both store cooling oil. Therefore, in this step S304, the original circulation chamber 102a can be designated as the circulation chamber 102a in the subsequent step S306 and the original temporary storage chamber 102b can be designated as the temporary storage chamber 102b in the subsequent step S305, or the original circulation chamber 102a can be designated as the temporary storage chamber 102b in the subsequent step S305 and the original temporary storage chamber 102b can be designated as the circulation chamber 102a in the subsequent step S306.

[0109] S305: Transfer the cooling oil in the designated temporary storage chamber 102b to the main chamber 101;

[0110] Specifically, step S305 can be refined to include:

[0111] S3051: Obtain the actual liquid level of the cooling oil in the main chamber 101;

[0112] S3052: If the actual liquid level is lower than the preset upper limit liquid level of the main chamber 101, it indicates that the cooling oil in the main chamber 101 is not full yet. At this time, the liquid inlet assembly 3 of the temporary storage chamber 102b can be opened to supplement the cooling oil to the main chamber 101 through the temporary storage chamber 102b until the actual liquid level reaches the preset upper limit liquid level of the main chamber 101;

[0113] Otherwise (that is, the actual liquid level reaches the preset upper limit liquid level of the main chamber 101), it indicates that the cooling oil in the main chamber 101 is full, and then the liquid inlet assembly 3 of the temporary storage chamber 102b can be closed to stop supplementing the cooling oil to the main chamber 101 through the temporary storage chamber 102b.

[0114] S306: Make the cooling oil circulate between the main chamber 101 and the specified secondary chamber 102, so as to continuously dissipate heat and cool down the server.

[0115] The maintenance method provided in this embodiment has the following advantages:

[0116] ① After taking in and out the server, the recycling of the cooling oil can be realized to avoid waste;

[0117] ② After taking in and out the server, the temporary storage chamber 102b and the circulation chamber 102a can be re-specified, which is flexible and changeable.
