Description

Data center cooling system based on immersion method using water, heat generating unit case and manufacturing method thereof

[0001] The present invention relates to a data center cooling system based on a water immersion method, a heat generating unit case, and a method for manufacturing the same, and more specifically, to a data center cooling system based on a water immersion method, a heat generating unit case, and a method for manufacturing the same, which can efficiently cool a data center through a water immersion method using water as a refrigerant by cooling the hardware of the data center by immersing it in water.

[0002] Recently, with the popularization of online ecosystems based on wired and wireless Internet, corporations, public institutions, broadcasters, and others are building IT infrastructure for data storage, management, and system operation. In particular, data processing centers capable of handling massive amounts of data are being built to implement systems that require processing, storing, managing, and operating massive amounts of data, such as platform provision systems for building online shopping malls, big data processing systems, and cloud infrastructure.

[0003] In general, systems that include large-scale computer hardware, such as data centers, generate a lot of heat due to the operation of the central processing unit, etc., so cooling devices must be installed to prevent damage to the equipment due to overload, fire, etc.

[0004] Therefore, conventional data center servers are equipped with heat sinks or cooling fans to dissipate generated heat to the outside. However, this air-cooling method suffers from poor cooling efficiency, resulting in excessive power consumption and low cooling effectiveness. In fact, 60 to 70 percent of the total energy consumed in data centers is actually spent on cooling.

[0005] Recently, liquid-based cooling methods have been proposed, offering superior cooling efficiency compared to air-cooling methods. Immersion cooling involves immersing a heat-generating unit in a non-conductive liquid to dissipate heat. This immersion cooling method is being studied as a solution for cooling computer hardware components used in data centers by submerging them in an insulating fluid.

[0006] These conventional liquid immersion cooling methods use non-conductive liquids such as fluorinated ketones, hydrofluoro ethers (HFEs), and perfluorinated compounds (PFCs) as refrigerants. Fluorinated ketones are artificially created by replacing hydrogen atoms in ketones with fluorine, and are fire retardants manufactured by 3M in 2002.

[0007] However, fluorinated compounds, including fluorinated ketones, are quite expensive. Consequently, implementing and maintaining large-scale cooling systems, such as data centers, using liquid immersion cooling is expensive. Therefore, there is an urgent need to develop an immersion cooling system that offers high cooling efficiency and high insulation while maintaining low equipment and maintenance costs.

[0008] The present invention is intended to solve such problems, and its purpose is to provide a data center cooling system, a heat generating unit case, and a manufacturing method thereof based on a water immersion method that uses water as a refrigerant to reduce installation and maintenance costs and provide excellent cooling efficiency.

[0009] To achieve the above object, one aspect of the present invention provides a data center cooling system based on a water immersion method.

[0018] The above-mentioned space may be filled with at least one material selected from the group consisting of silicon, silica nanoparticles, fluorine-based resin, Parylene N, Parylene C, Parylene F, polyurethane, epoxy resin, ceramic material, and acrylic.

[0019] The control unit can analyze sensing information collected from a sensor within the heat generating unit package and control the water circulation unit so that the temperature of the heat generating unit is maintained within a predetermined temperature range. The water circulation unit can supply water at a predetermined temperature to the chamber or discharge water within the chamber according to the control of the control unit.

[0020] The above control unit can control the water circulation unit to discharge water within the chamber to a predetermined level when a water leak detection signal is received from a sensor within the heating unit package.

[0021] In order to achieve the above-described object, one aspect of the present invention provides a heat generating unit case.

[0028] In a state where the first case is accommodated in the second receiving portion of the second case, a space spaced apart by a set distance along the outer surface of the first case can be formed between the first case and the second receiving portion of the second case.

[0029] The above-mentioned space may be filled with at least one material selected from the group consisting of silicon, silica nanoparticles, fluorine-based resin, Parylene N, Parylene C, Parylene F, polyurethane, epoxy resin, ceramic material, and acrylic.

[0030] In order to achieve the above-described object, one aspect of the present invention provides a method for manufacturing a heat generating unit case. The method for manufacturing a heat generating unit case may include a cooling system including a chamber formed to contain water therein and immerse a heat generating unit package in the contained water, a water circulation unit for supplying water into or discharging water from the chamber and maintaining the temperature of the water in the chamber such that the temperature of a heat generating unit included in the heat generating unit package is maintained within a predetermined temperature range, and a control unit for collecting sensing information from a sensor in the heat generating unit package and analyzing the collected sensing information to control the water circulation unit, wherein a method for manufacturing a heat generating unit case for accommodating the heat generating unit may include the steps of: generating, at a server, a case design drawing having a receiving portion corresponding to the external shape information of the heat generating unit using an artificial intelligence engine; transmitting the case design drawing to a 3D printer; and generating, by the 3D printer, a heat generating unit case having a receiving portion formed therein to correspond to the external shape of the heat generating unit and capable of forming the heat generating unit package by accommodating the heat generating unit in the receiving portion, based on the case design drawing.

[0055] The present invention is susceptible to various modifications and embodiments. Specific embodiments are illustrated and described in detail in the drawings. However, this is not intended to limit the present invention to specific embodiments, but rather to encompass all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention.

[0056] While terms such as "first" and "second" may be used to describe various components, these components should not be limited by these terms. These terms are used solely to distinguish one component from another. For example, without departing from the scope of the present invention, a first component may be referred to as a "second component," and similarly, a second component may also be referred to as a "first component." The term "and / or" includes any combination of multiple related items described herein or any item among multiple related items described herein.

[0057] Hereinafter, with reference to the attached drawings, preferred embodiments of the present invention will be described in more detail. In order to facilitate an overall understanding in describing the present invention, identical reference numerals will be used for identical components in the drawings, and redundant descriptions of identical components will be omitted.

[0058] Figure 1 is a schematic diagram showing the configuration of a system for liquid immersion cooling using water according to a preferred embodiment of the present invention.

[0059] As illustrated in FIG. 1, water (20) is contained inside the chamber (10) as a refrigerant for cooling the heat generated from the heat generating unit. The heat generating unit is accommodated by the heat generating unit case to form a heat generating unit package. The heat generating unit package is cooled by being immersed (i.e., precipitated) in the water (20) contained in the chamber (10). The water circulation unit (30) can supply water (20) into the chamber (10) or discharge water (20) from the chamber (10). That is, the water circulation unit (30) can circulate the water (20) within the chamber (10). For example, the water circulation unit (30) can control and maintain the temperature of the water (20) within the chamber (10) so that the temperature of the heat generating unit is maintained within a predetermined temperature range. The control unit (40) can collect sensing information from a sensor within the heat generating unit package and analyze the collected sensing information to control the water circulation unit (30).

[0060] The above-described heat generating unit may be a hardware device constituting a data center. For example, the heat generating unit may be a server device, a component, a circuit board, or a hardware package containing such components. In the description of the present embodiments, the server device is assumed to be a hardware package. However, this is not limited, and the heat generating unit refers to all devices, components, circuit boards, etc. constituting a server.

[0061] These heat generating units are packaged by a heat generating unit case. The heat generating unit case is made of an electrically insulating material and has a receiving portion formed to correspond to the outer shape of the heat generating unit therein, and the heat generating unit package is accommodated in the receiving portion. The heat generating unit case accommodates and strictly seals the heat generating unit, thereby preventing water (20) from flowing into the heat generating unit. In this way, a structure in which the heat generating unit case accommodates the heat generating unit and is electrically insulated from an external fluid and can be safely precipitated in water (20) within the chamber (10) is referred to as a heat generating unit package. That is, the heat generating unit package is formed by accommodating the heat generating unit in the receiving portion of the heat generating unit case. The heat generating unit package is sealed by the heat generating unit case, so that water (20) does not penetrate into the heat generating unit.

[0062] A heating unit package may include one or more heating unit cases. Fig. 2 is a cross-sectional view illustrating the structure of a heating unit package according to one embodiment of the present invention, showing a heating unit package including one heating unit case.

[0063] As illustrated in FIG. 2, the heat generating unit package (100) is formed by a first heat generating unit case (110) encasing the heat generating unit (50). The first heat generating unit case (110) is formed to correspond to the outer shape of the heat generating unit (50) and has a first receiving portion (111) capable of accommodating and seating the heat generating unit (50).

[0064] In a state where the heating unit (50) is installed in the first receiving portion (111), the inner surface of the first receiving portion (111) may be in close contact with the outer surface of the heating unit (50), or the inner surface of the first receiving portion (111) may be in contact with the outer surface of the heating unit (50) at a predetermined distance.

[0065] FIG. 3 is a cross-sectional view illustrating the structure of a heat generating unit package according to one embodiment of the present invention, showing a heat generating unit package including a plurality of heat generating unit cases.

[0066] As illustrated in FIG. 3, the heat generating unit package (101) may include a first heat generating unit case (110) and a second heat generating unit case (120). The first heat generating unit case (110) may have a first receiving portion (111) formed to correspond to the outer surface shape of the heat generating unit (50) so as to accommodate and secure the heat generating unit (50). The second heat generating unit case (120) may have a second receiving portion (121) formed to correspond to the outer surface shape of the first heat generating unit case (110) so as to accommodate the first heat generating unit case (110).

[0067] The heating unit case can be formed of an electrically insulating material such as polycarbonate, polyurethane, epoxy resin, polytetrafluoroethylene (PTFE, Teflon), fiber-reinforced plastic (FRP), silicone, polymethyl methacrylate (PMMA, acrylic), aluminum with ceramic, etc.

[0068] In one embodiment of the present invention, the first heat generating unit case (110) may be formed of a first electrically insulating material, and the second heat generating unit case (120) may be formed of a second electrically insulating material. Here, the first electrically insulating material and the second electrically insulating material may be different materials. That is, the first heat generating unit case (110) and the second heat generating unit case (120) may be formed of the above-mentioned electrically insulating material, but may be cases formed of different materials.

[0069] In a state where the heating unit (50) is installed in the first receiving portion (111), the inner surface of the first receiving portion (111) may be in close contact with the outer surface of the heating unit (50), or the inner surface of the first receiving portion (111) may be in contact with the outer surface of the heating unit (50) at a predetermined distance.

[0070] In a state where the first heating unit case (110) is installed in the second receiving portion (121), the inner surface of the second receiving portion (121) may be in close contact with the outer surface of the first heating unit case (110), or the inner surface of the second receiving portion (121) may be in contact with the outer surface of the first heating unit case (110) at a predetermined distance apart from each other.

[0071] For example, when the first heat generating unit case (110) is accommodated in the second receiving portion (121) of the second heat generating unit case (120), a space may be formed between the first heat generating unit case (110) and the second receiving portion (121) of the second heat generating unit case (120) at a set distance along the outer surface of the first heat generating unit case (110). At least one material may be filled in this space.

[0072] FIG. 4 is a cross-sectional view showing a state in which a specific material is filled between a plurality of heating unit cases according to one embodiment of the present invention.

[0073] As illustrated in FIG. 4, when the first heat generating unit case (110) is accommodated in the second receiving portion (121) of the second heat generating unit case (120), a space spaced apart by a set distance is formed along the outer surface of the first heat generating unit case (110) between the first heat generating unit case (110) and the second receiving portion (121) of the second heat generating unit case (120), and at least one material may be filled in this space space to form a filling layer.

[0074] For example, the above-mentioned space may be filled with at least one material selected from the group consisting of silicon, silica nanoparticles, fluorine-based resin, Parylene N, Parylene C, Parylene F, polyurethane, epoxy resin, ceramic material, and acrylic.

[0075] Meanwhile, according to one embodiment of the present invention, the heat generating unit case may include a connecting portion that is detachably connected to another heat generating unit case. That is, the heat generating unit package may be connected to another heat generating unit package by the connecting portion. When the heat generating unit cases are in a state where they are in contact with each other, the heat generating unit case and the other heat generating unit case are spaced apart by a predetermined distance, and when the heat generating unit cases are immersed in water (20), the space formed by the separation is filled with water (20).

[0076] Figure 5 is a cross-sectional view showing a state in which heat generating unit packages are connected to each other based on a connection formed in a heat generating unit case.

[0077] As illustrated in FIG. 5, a connection portion (200a) is formed on one side of a heat generating unit case (100a), and a connection portion (200b) is formed on the opposite side of another heat generating unit case (100b) to be aligned with and fastened to the connection portion (200a) of the heat generating unit case (100a). For example, in the example illustrated in FIG. 5, the heat generating unit case (100a) and the other heat generating unit case (100b) are fastened by a sliding fastening structure (200a, 200b) that slides from the side while matching the male and female. Meanwhile, the sliding fastening structure (200a, 200b) can be detached by sliding in the opposite direction again in a fastened state. In other words, the two heat generating unit cases (100a, 100b) are detachable from each other.

[0078] In a state where a heat generating unit case (100a) and another heat generating unit case (100b) are connected by a fastening structure (200a, 200b), a separation space (210) determined by the physical shape of the connecting portion fastening structure (200a, 200b) is secured between the heat generating unit case (100a) and the other heat generating unit case (100b). The separation space (210) secured in this way is filled with water (20). Therefore, even in a structure where a plurality of heat generating unit cases are connected, a structure in which water (20) circulates is naturally secured, thereby preventing a decrease in cooling efficiency.

[0079] Figure 6 is a cross-sectional view showing a state in which heat generating unit packages are connected to each other based on a plurality of connecting portions formed in a heat generating unit case.

[0080] As shown in Fig. 5, a first connection part (200d) is formed on one side of the heat generating unit case (100a), and a second connection part (200c) is formed on the opposite side of the other heat generating unit case (100b) to be aligned and fastened with the first connection part (200d) of the heat generating unit case (100a).

[0081] Additionally, a third connection part (200f) is formed on the other side of the heating unit case (100a), and a fourth connection part (200e) is formed on the opposite side of another heating unit case (100b) to be aligned and connected with the third connection part (200f) of the heating unit case (100a).

[0082] In the example illustrated in Fig. 6, the heat generating unit case (100a) and another heat generating unit case (100b) are fastened by a plurality of sliding fastening structures (200d-200c, 200f-200e) that slide from the side to match the male and female sides. Meanwhile, these plurality of sliding fastening structures (200d-200c, 200f-200e) can be detached by sliding in the opposite direction again while in a mutually fastened state. In other words, the two heat generating unit cases (100a, 100b) are mutually detachable.

[0083] In a state where a heat generating unit case (100a) and another heat generating unit case (100b) are connected by a plurality of fastening structures (200d-200c, 200f-200e), a separation space (210) determined by the physical shape of the plurality of connecting fastening structures (200d-200c, 200f-200e) is secured between the heat generating unit case (100a) and the other heat generating unit case (100b). The separation space (210) secured in this way is filled with water (20). Therefore, even in a structure where a plurality of heat generating unit cases are fastened by a plurality of fastening structures, a structure in which water (20) circulates is naturally secured, thereby preventing a decrease in cooling efficiency.

[0084] According to one embodiment of the present invention, the connection between the plurality of heating unit cases can be implemented not only by the aforementioned sliding method, but also by a screw-based connection structure, a magnet-based connection structure, a force-fit structure, etc.

[0085] Fig. 7 is an exemplary diagram showing an example of arranging a plurality of heat generating unit cases by connecting them laterally according to one embodiment of the present invention. As illustrated in Fig. 7, based on connecting a plurality of heat generating unit cases laterally, an integrated package including a plurality of heat generating unit packages can be formed in a form in which the plurality of heat generating unit packages are laterally stacked. In this case, the plurality of heat generating unit packages are immersed in water (20) within the chamber (10) while being connected laterally or transversely.

[0086] Fig. 8 is an exemplary diagram showing an example of arranging a plurality of heat generating unit cases by connecting them upwards according to one embodiment of the present invention. As illustrated in Fig. 8, based on connecting a plurality of heat generating unit cases upwards, an integrated package including a plurality of heat generating unit packages can be formed by stacking a plurality of heat generating unit packages upwards. In this case, a plurality of heat generating unit packages are contained in the chamber (10) in a state of being connected upwards or in a vertical direction.

[0087] According to one embodiment of the present invention, an integrated case may be provided that accommodates a plurality of heat generating unit packages. A large-scale data center package may be formed by accommodating a plurality of interconnected heat generating unit packages within the integrated case.

[0088] Meanwhile, a water leak detection sensor for water leak detection may be provided on one side of the heating unit case. Referring to FIGS. 2 and 3, for example, the first heating unit case (110) illustrated in FIG. 2 is provided with a water leak detection sensor for water leak detection.

[0089] As illustrated in FIG. 3, when a plurality of heating unit cases are provided in a heating unit package, the first heating unit case (110) may include a first individual water leak detection sensor, and the second heating unit case (120) may include a second individual water leak detection sensor.

[0090] In this way, when multiple heating unit cases are provided and each heating unit case is provided with an individual water leak detection sensor, the location of the water leak can be easily identified and maintenance is also easier.

[0091] For example, as shown in FIGS. 7 and 8, when a plurality of heating unit cases corresponding to a plurality of heating units are provided, each heating unit case may be provided with an individual water leak detection sensor for water leak detection, and an integrated case water leak detection sensor for detecting water leaks in the integrated case may be provided on one side of an integrated case that accommodates a plurality of heating unit cases.

[0092] When a water leak detection signal is received from a sensor within the heating unit package, the control unit (40) can control the water circulation unit (30) to discharge water (20) within the chamber (10) to a predetermined level. For example, when a water leak detection signal is received from a sensor provided in a specific heating unit package, water (20) can be discharged to a preset level corresponding to the heating unit package so that water (20) no longer flows into the heating unit package.

[0093] The control unit (40) can analyze sensing information collected from a sensor within the heat generating unit package and control the water circulation unit (30) so that the temperature of the heat generating unit (50) is maintained within a predetermined temperature range. The water circulation unit (30) can supply water (20) at a predetermined temperature to the chamber (10) or discharge water (20) within the chamber (10) under the control of the control unit (40).

[0094] Meanwhile, sensors for detecting changes in the environment to protect the data center, such as temperature sensors and humidity sensors, may be provided within the heat generating unit package, and the control unit (40) may analyze sensing information received from these sensors and perform a corresponding action to control the water circulation unit (30) and the like along a predetermined route based on the analyzed information.

[0095] FIG. 9 is a flowchart illustrating a process for manufacturing a heating unit case according to one embodiment of the present invention.

[0096] As illustrated in Fig. 9, a server controlling the manufacturing of a heat generating unit case can obtain external shape information of a heat generating unit (50) and then use an artificial intelligence engine based on the obtained external shape information to generate a case design drawing having a receiving portion corresponding to the external shape information (step: S1).

[0097] Next, the server can transmit the case design drawing to a 3D printer (step: S2). Then, the 3D printer can generate a heat generating unit case that can form the heat generating unit package by having a receiving portion formed to correspond to the external shape of the heat generating unit (50) inside based on the received case design drawing and receiving the heat generating unit (50) in the receiving portion (step: S3).

[0098] FIG. 10 is a schematic diagram showing the configuration of a system for liquid immersion cooling using water (20) according to a preferred embodiment of the present invention. Hereinafter, an embodiment of forming a heat generating unit package based on a multilayer coating will be examined.

[0099] As illustrated in Fig. 10, water (20) is contained inside the chamber (10) as a refrigerant for cooling the heat generated from the heat generating unit. In the present embodiment, a heat generating unit package corresponding to the heat generating unit is formed by multi-layer coating the surface of the heat generating unit with at least one electrically insulating material to prevent water (20) from penetrating into the heat generating unit while maintaining heat conductivity.

[0100] The heat generating unit package (300) is immersed in water (20) contained in the chamber (10) and cooled by transferring heat generated from the heat generating unit (50) to the water (20). The water circulation unit (30) can supply water (20) into the chamber (10) or discharge water (20) from the chamber (10). That is, the water circulation unit (30) can circulate the water (20) within the chamber (10). For example, the water circulation unit (30) can control and maintain the temperature of the water (20) within the chamber (10) so that the temperature of the heat generating unit (50) is maintained within a predetermined temperature range. The control unit (40) can collect sensing information from a sensor within the heat generating unit package and analyze the collected sensing information to control the water circulation unit (30).

[0101] The above-described heat generating unit (50) may be a hardware device constituting a data center. For example, the heat generating unit (50) may be a server device, or a component, a substrate, or a hardware package in which these components are encased within the server device. In the description of the present embodiments, it is assumed that the server device is a hardware package. However, this is not limited, and the heat generating unit (50) refers to all devices, components, substrates, etc. constituting the server.

[0102] FIG. 11 is a flowchart illustrating a process for manufacturing a heating unit package according to a preferred embodiment of the present invention.

[0103] As illustrated in Fig. 11, the manufacturing device sets the heating unit on the process line to apply a multilayer coating to the heating unit (step: S11). The manufacturing device can apply a multilayer coating to the surface of the heating unit with at least one electrically insulating material to prevent water (20) from penetrating into the heating unit while maintaining thermal conductivity (step: S12).

[0104] Here, the multilayer coating may be a coating in which a basic coating layer, an electrical insulation layer, a heat dissipation layer, a waterproof and moisture-proof protective layer, and an outer protective layer are sequentially laminated from the outer surface of the heating unit.

[0105] Hereinafter, with reference to FIGS. 12 to 16, this multilayer coating will be examined in more detail.

[0106] Fig. 12 is a cross-sectional view exemplarily showing a state in which a basic coating layer is formed on the outer surface of a heating unit.

[0107] Referring to Fig. 12, a basic coating layer (310) is formed on the outer surface of the heating unit (50). The basic coating layer (310) can be formed by performing primer coating. The primer coating can be formed by applying at least one of a silicone primer and a polyurethane primer to the surface of the heating unit (50) and drying it to strengthen the adhesion between the hardware component of the heating unit (50) and the upper coating layer and to make the component surface uniform.

[0108] This basic coating layer (310) provides strong adhesion to the surface of the heating unit (50), such as a package or component, so that the coating to be applied later can be evenly attached, and can fill in fine defects or imbalances on the surface to ensure consistency of the coating.

[0109] Fig. 13 is a cross-sectional view exemplarily showing a state in which an electrical insulation layer is formed on the surface of a basic coating layer (310).

[0110] As illustrated in Fig. 13, an electrical insulation layer (320) is laminated on the surface of the basic coating layer (310). The electrical insulation layer (320) can be formed by performing a non-conductive insulation coating. The non-conductive insulation coating can be formed by performing at least one of vacuum deposition and coating using at least one of parylene, polyurethane, epoxy, and nano-silica to block electrical conductivity between the heating unit (50) and the outside to prevent electrical short-circuiting when in contact with water (20).

[0111] The above-mentioned electrical insulation layer (320) provides very high electrical insulation, so that the heating unit (50) can be protected from electrical damage even when the heating unit (50) and water (20) come into direct contact, and thin and uniform application is possible.

[0112] Fig. 14 is a cross-sectional view showing an example of a state in which a heat dissipation layer is formed on the surface of an electrical insulation layer (320).

[0113] As illustrated in Fig. 14, a heat dissipation layer (330) is formed and laminated on the surface of the electrical insulation layer (320). The heat dissipation layer (330) can be formed by performing a thermally conductive coating. The thermally conductive coating is intended to quickly transfer heat generated from the heat generating unit (50) to water (20) to increase thermal conductivity, and the heat dissipation layer can be formed by performing one of coating, vacuum deposition, and nano-coating using at least one of alumina (Al2O3), aluminum nitride (AlN), and silicon-based nanomaterials.

[0114] This heat dissipation layer (330) helps to maximize the cooling effect by quickly dispersing heat without it accumulating inside the heat generating unit (50), and adopts a material that provides excellent thermal conductivity along with electrical insulation, thereby ensuring both cooling efficiency and stability.

[0115] Fig. 15 is a cross-sectional view exemplarily showing a state in which a waterproof and moisture-proof protective layer is formed on the surface of a heat dissipation layer (330).

[0116] As shown in Fig. 15, a waterproof and moisture-proof protective layer is formed and laminated on the surface of the heat dissipation layer (330).

[0117] The above waterproof and moisture-proof protective layer (340) can be formed by applying a fluorine-based material and silicone rubber on the heat dissipation layer to protect the heating unit (50) from physical contact with water (20) and prevent water (20) from penetrating. The above waterproof and moisture-proof protective layer can prevent performance degradation even when immersed in water (20) for a long period of time by increasing waterproofing and moisture resistance, and can protect the coating from damage by having excellent flexibility and durability.

[0118] Fig. 16 is a cross-sectional view exemplarily showing a state in which an outer protective layer is formed on the surface of a waterproof and moisture-proof protective layer.

[0119] As illustrated in Fig. 16, an outer protective layer (350) is formed and laminated on the surface of the waterproof and moisture-proof protective layer (340). The outer protective layer (350) may be formed by a durable and chemically resistant coating. The durable and chemically resistant coating may be formed by applying polyurethane, acrylic, or epoxy on the waterproof and moisture-proof protective layer (340) to protect the heating unit (50) from external physical impact, wear, and chemical corrosion.

[0120] The above outer protective layer (350) can extend the life of the coating by protecting it from external physical impact or wear and tear and can extend the life of the coating from corrosive substances or other chemical factors.

[0121] The multilayer coated heating unit (50) may be subjected to at least one of a battery insulation test to check whether the multilayer coated heating unit (50) is completely electrically insulated and operates without electrical damage from water (20) under test conditions, a waterproof test to check whether the multilayer coated heating unit (50) operates without water leakage under test conditions, and a heat dissipation test to check whether the multilayer coated heating unit (50) dissipates a set amount of heat into water (20) under test conditions.

[0122] Meanwhile, the control unit (40) can analyze sensing information collected from a sensor that detects the condition of the heating unit (50) and control the water circulation unit (30) so that the temperature of the heating unit (50) is maintained below a predetermined temperature. The water circulation unit (30) can supply water (20) at a predetermined temperature to the chamber (10) or discharge water (20) within the chamber (10) according to the control of the control unit (40).

[0123] The above control unit (40) can control the water circulation unit (30) to discharge water (20) within the chamber (10) to a predetermined level when a water leak detection signal is received from a sensor within the heating unit package.

[0124] FIG. 17 is a schematic diagram showing the configuration of a system for liquid immersion cooling using water (20) according to a preferred embodiment of the present invention. Hereinafter, an embodiment of forming a heat generating unit package based on a heat generating unit case and a multilayer coating will be examined.

[0125] As illustrated in Fig. 17, water (20) is contained inside the chamber (10) as a refrigerant for cooling the heat generated from the heat generating unit (50). In the present embodiment, the heat generating unit (50) is accommodated by at least one heat generating unit case and is coated by a multi-layer coating layer using a plurality of different materials to form a heat generating unit package (400).

[0126] The above-mentioned heat generating unit package (400) may include at least one heat generating unit case that accommodates the heat generating unit (50) and a multi-layer coating layer using a plurality of different materials so as to prevent water (20) from penetrating the heat generating unit (50) while maintaining thermal conductivity with water (20).

[0127] The heating unit package (400) is cooled by being immersed in (i.e., settled in) water (20) contained in the chamber (10). The water circulation unit (30) can supply water (20) into the chamber (10) or discharge water (20) from the chamber (10). That is, the water circulation unit (30) can circulate the water (20) within the chamber (10). For example, the water circulation unit (30) can control and maintain the temperature of the water (20) within the chamber (10) so that the temperature of the heating unit (50) is maintained within a predetermined temperature range. The control unit (40) can collect sensing information from a sensor within the heating unit package and analyze the collected sensing information to control the water circulation unit (30).

[0128] The above-described heat generating unit (50) may be a hardware device constituting a data center. For example, the heat generating unit (50) may be a server device, or a component, a substrate, or a hardware package in which these components are encased within the server device. In the description of the present embodiments, it is assumed that the server device is a hardware package. However, this is not limited, and the heat generating unit (50) refers to all devices, components, substrates, etc. constituting the server.

[0129] FIG. 18 is a flowchart illustrating a process for manufacturing a heating unit package according to a preferred embodiment of the present invention.

[0130] As illustrated in Fig. 18, the manufacturing device can create at least one heating unit case that accommodates the heating unit (50) using an electrically insulating material based on a 3D printer (step: S21).

[0131] When at least one heat generating unit case is created, the manufacturing device can form a multilayer coating layer using a plurality of different materials that is formed to contact at least one of the heat generating unit cases so that the heat generating unit (50) is secured in the heat generating unit case and then casing the heat generating unit (50) so that water (20) does not penetrate the heat generating unit (50) but maintains thermal conductivity with the water (20) (step: S22).

[0132] Fig. 19 is a cross-sectional view exemplarily showing a heating unit package in which a heating unit (50) is placed in a heating unit case, a multi-coating layer is formed, and then the case is cased.

[0133] As illustrated in Fig. 19, the first heat generating unit case (410) may be provided with a first receiving portion (411) for receiving the heat generating unit (50). The first receiving portion (411) is formed to allow the heat generating unit (50) to be placed and seated in accordance with the external shape of the heat generating unit (50). When the heat generating unit (50) is seated in the first receiving portion (411), the inner surface of the first receiving portion (411) may face the outer surface of the heat generating unit (50) so as to be in close contact with the outer surface of the heat generating unit (50), or the inner surface of the first receiving portion (411) may face the outer surface of the heat generating unit (50) at a predetermined distance along the outer surface.

[0134] The first heating unit case (400) may be formed of a first electrically insulating material. For example, the heating unit case may be formed of an electrically insulating material such as polycarbonate, polyurethane, epoxy resin, polytetrafluoroethylene (PTFE, Teflon), fiber-reinforced plastic (FRP), silicone, polymethyl methacrylate (PMMA, acrylic), aluminum with ceramic, etc.

[0135] A multilayer coating layer may be formed on the outer surface of the first heating unit case (410) that accommodates the heating unit (50). Here, the multilayer coating may be a coating in which a basic coating layer (420), an electrical insulation layer (430), a heat dissipation layer (440), a waterproof and moisture-proof protective layer (440), and an outer protective layer (450) are sequentially laminated from the outer surface of the first heating unit.

[0136] Referring to Fig. 19, a basic coating layer (420) is formed on the outer surface of the first heating unit case (400). The basic coating layer (420) can be formed by performing primer coating. The primer coating can be applied to the surface of the heating unit (50) using at least one of a silicone primer and a polyurethane primer and dried to form a basic coating layer in order to strengthen the adhesion between the hardware component of the heating unit (50) and the upper coating layer and to make the component surface uniform.

[0137] This basic coating layer (420) provides strong adhesion to the surface of the heating unit (50), such as a package or component, so that the coating to be applied later can be evenly attached, and can fill in fine defects or imbalances on the surface to ensure consistency of the coating.

[0138] As illustrated in Fig. 19, an electrical insulation layer (430) is laminated on the surface of the basic coating layer (420). The electrical insulation layer (430) can be formed by performing a non-conductive insulation coating. The non-conductive insulation coating can be formed by performing at least one of vacuum deposition and coating using at least one of parylene, polyurethane, epoxy, and nano-silica to block electrical conductivity between the heating unit (50) and the outside to prevent electrical short-circuiting when in contact with water (20).

[0139] The above-mentioned electrical insulation layer (430) provides very high electrical insulation, so that the heating unit (50) can be protected from electrical damage even when the heating unit (50) and water (20) come into direct contact, and thin and uniform application is possible.

The thermally conductive coating is intended to quickly transfer heat generated from the heat generating unit (50) to water (20) to increase thermal conductivity, and the heat dissipation layer (440) can be formed by performing one of coating, vacuum deposition, and nano-coating using at least one of alumina (Al2O3), aluminum nitride (AlN), and silicon-based nanomaterials.

[0141] This heat dissipation layer (440) helps to maximize the cooling effect by quickly dispersing heat without it accumulating inside the heat generating unit (50), and adopts a material that provides excellent thermal conductivity along with electrical insulation, thereby ensuring both cooling efficiency and stability.

[0142] A waterproof and moisture-proof protective layer (450) is formed and laminated on the surface of the heat dissipation layer (440). The waterproof and moisture-proof protective layer (450) can be formed by applying a fluorine-based material and silicone rubber onto the heat dissipation layer (440) to protect the heat generating unit (50) from physical contact with water (20) and prevent water (20) from penetrating. The waterproof and moisture-proof protective layer can prevent performance degradation even when immersed in water for a long time by increasing waterproofing and moisture resistance, and can protect the coating from damage by having excellent flexibility and durability.

[0143] An outer protective layer (460) is formed and laminated on the surface of the waterproof and moisture-proof protective layer (450). The outer protective layer (460) can be formed by a durable and chemically resistant coating. The durable and chemically resistant coating can be formed by applying polyurethane, acrylic, or epoxy on the waterproof and moisture-proof protective layer to protect the heating unit (50) from external physical impact, wear, and chemical corrosion.

[0144] The above outer protective layer can extend the life of the coating by protecting it from external physical impact or wear and tear and can extend the life of the coating from corrosive substances or other chemical factors.

[0145] The first heat generating unit case (410) on which the multilayer coating layers are laminated is accommodated by the second heat generating unit case (470). The second heat generating unit case (470) may include a second receiving portion (471) that accommodates the first heat generating unit case (410) on which the multilayer coating layers are laminated so as to be in close contact with the uppermost layer of the multilayer coating layers. That is, when the second receiving portion of the second heat generating unit case (470) accommodates the first heat generating unit case (410) on which the multilayer coating layers are laminated, the second receiving portion (471) of the second heat generating unit case (470) is in close contact with the uppermost layer of the facing multilayer coating layers, for example, the outer protective layer.

That is, the first heating unit case (410) and the second heating unit case (470) may be made of the electrically insulating material mentioned above, but may be cases made of different materials.

[0148] In one embodiment described with reference to FIG. 19, an embodiment is described in which a heat generating unit (50) is cased with a first heat generating unit case (410), a multi-layer coating layer is formed on the first heat generating unit case (410), and then the case is cased with a second heat generating unit case (470).
