Description

High-efficiency immersion cooling system equipped with a cooling water flow motor driven by heat from immersion cooling oil and a control method thereof

[0001] The present invention relates to an immersion cooling system, and more specifically, to a high-efficiency immersion cooling system equipped with a cooling water flow motor driven by the heat of the immersion cooling oil, wherein the cooling water flow motor is driven by self-power using the heat of the immersion cooling oil, thereby facilitating the circulation of the immersion cooling oil by driving the cooling water flow motor, and a control method thereof.

[0002] Immersion cooling is a technology that uses liquid to cool electronic devices such as servers. Instead of traditional air cooling methods, more effective heat dissipation and energy efficiency can be achieved by immersing servers or data center equipment in insulating fluid. This technology is particularly useful for high-performance computing or large-scale data centers and is a field receiving increasing attention due to the recent rise in demands for improved energy efficiency and sustainability in data centers.

[0003] Conventional air cooling methods rely on numerous fans or air conditioners to dissipate heat within large servers; however, this approach is inefficient in large-scale data centers, and adequate thermal management becomes difficult with air cooling as server density increases. Furthermore, air cooling requires relatively large spaces and high power consumption. In contrast, immersion cooling utilizes insulating liquids with much higher heat transfer efficiency than air, allowing it to effectively absorb more heat while using less energy. Particularly in high-density server environments, it enables heat control with significantly less space and resources than air cooling, drastically reducing energy consumption and lowering the costs associated with fans and air circulation systems. Consequently, overall power consumption decreases, leading to reduced operating costs. Unlike traditional air cooling, immersion cooling systems absorb heat by directly submerging server hardware in cooling fluid. The heat-absorbing fluid is then released externally to remove heat via heat exchangers before being recirculated.

[0051] The above switch (134) is electrically connected to the second charging unit (120) and electrically connected to the cooling water motor (108), and is also electrically connected to the control unit (110), so that it is switched ON by a control signal from the control unit (110) to send electrical energy (or voltage) to the cooling water motor (108).

[0052] The manufacturing process of a high-efficiency cooling liquid immersion cooling system (100) equipped with a cooling water flow motor driven by the heat of the liquid immersion cooling oil according to the present invention, as described above, is as follows.

[0053] Here, the manufacturing process of the high-efficiency cooling immersion cooling system (100) equipped with a cooling water flow motor driven by the heat of the immersion cooling oil according to the present invention can be changed at any time depending on the manufacturer.

[0054] First, a liquid immersion cooling tank (102) having an internal storage space is prepared, and a server unit (106) is prepared.

[0055] Then, a cooling water flow motor (108) equipped with a shaft (not shown) is installed on one side of the server unit (106), and a control unit (110) is installed on one side of the cooling water flow motor (108).

[0056] And, a cooling water flow motor (108) is electrically connected to the control unit (110).

[0057] Then, a temperature measuring unit (112) is installed on one side of the server unit (106) at a certain distance from the control unit (110), and the temperature measuring unit (112) is electrically connected to the control unit (110).

[0058] Then, a flow rate measuring unit (114) is installed on one side of the server unit (106) at a certain distance from the temperature measuring unit (112), and the flow rate measuring unit (114) is electrically connected to the control unit (110).

[0059] Then, a flow rate measuring unit (116) is installed on one side of the server unit (106) at a certain distance from the flow rate measuring unit (114), and the flow rate measuring unit (116) is electrically connected to the control unit (110).

[0060] And, a water flow generating means (118) is installed on one side of the cooling water flow motor (108) at a certain distance from the above-mentioned flow rate measuring unit (116).

[0061] Looking further into the installation process of the above-mentioned water flow generating means (118), a thermoelectric element (120) is installed on one side of the cooling water flow motor (108) at a certain distance from the control unit (110).

[0062] Here, the thermoelectric element (120) receives heat generated from the liquid immersion cooling oil, converts the received heat into electrical energy, and sends the converted electrical energy to the first charging section and the second charging section.

[0063] Then, a first charging unit (122) is installed on one side of the cooling water flow motor (108) at a certain distance from the thermoelectric element (120), and the first charging unit (122) is electrically connected to the control unit (110) and the thermoelectric element (120).

[0064] And, a guide tube (128) having an intake port (124) and an exhaust port (126) is installed on one side of the cooling water flow motor (108) at a certain distance from the first charging part (122).

[0065] Then, after positioning the impeller (130) on one side inside the induction tube (128), the impeller (130) is installed on the shaft of the cooling water flow motor (108).

[0066] Here, the impeller (130) rotates according to the operation of the cooling water flow motor (108) to draw in the liquid immersion cooling oil through the suction port (124) of the guide pipe (128) and discharges the drawn-in liquid immersion cooling oil through the discharge port (126) of the guide pipe (128) to generate a water flow and cool the liquid immersion cooling oil.

[0067] The reason for generating the above-mentioned water flow (i.e., generating turbulence in the immersion cooling oil) is to enhance the cooling effect of the immersion cooling oil by increasing the absorption of heat generated by the data server.

[0068] Then, after installing a second charging unit (132) on one side of the cooling water flow motor (108), the second charging unit (132) is electrically connected to the thermoelectric element (120).

[0069] Then, after positioning the switch (134), the switch (134) is electrically connected to the second charging unit (120) and the cooling water flow motor (108).

[0070] And, a switch (134) is electrically connected to the control unit (110).

[0071] The operation (or control method) of the high-efficiency cooling liquid immersion cooling system (100) equipped with a cooling water flow motor driven by the heat of the liquid immersion cooling oil according to the present invention, manufactured as described above, is as follows.

[0072] Prior to the operation of the high-efficiency cooling immersion cooling system (100) equipped with a cooling water flow motor driven by the heat of the immersion cooling oil according to the present invention,

[0073] A data server (200) with electronic devices (not shown in the drawing) installed is positioned in the receiving space of the above-mentioned liquid cooling tank (102) as shown in FIG. 2.

[0074] Here, it is preferable that at least one data server (200) be located in the receiving space of the liquid immersion cooling tank (102).

[0075] When the data server (200) is positioned in the receiving space of the liquid immersion cooling tank (102) as described above, the data server (200) is electrically connected to an external device (not shown). Then, as shown in FIG. 2, liquid immersion cooling oil is introduced into the receiving space of the liquid immersion cooling tank (102).

[0076] Then, a server unit (106) including a cooling water flow motor (108), a control unit (110), a temperature measuring unit (112), a flow rate measuring unit (114), a flow velocity measuring unit (116), and a water flow generating means (118) is positioned in the receiving space of the above-mentioned liquid immersion cooling tank (102).

[0077] Here, the above-mentioned water flow generating means (118) includes a thermoelectric element (120), a first charging part (122), an induction tube (128) having an intake port (124) and an exhaust port (126), an impeller (130), a second charging part (132), and a switch (134).

[0078] Then, the data server (200) and server unit (106) housed in the housing space of the above-mentioned liquid immersion cooling tank (102) are operated.

[0079] When the server unit (106) and data server (200) are operated as described above,

[0080] Heat is generated in the above server unit (106) and data server (200). At this time, the liquid immersion cooling oil introduced into the receiving space of the above liquid immersion cooling tank (102) cools the heat generated in the above server unit (106) and data server (200).

[0081] When the liquid immersion cooling oil introduced into the receiving space of the above liquid immersion cooling tank (102) cools the heat generated in the above server unit (106) and data server (200),

[0082] The above-mentioned immersion cooling oil begins to heat up gradually. In other words, the heat of the above-mentioned immersion cooling oil rises.

[0083] As described above, when the heat of the liquid immersion cooling oil rises, the thermoelectric element (120) receives the heat generated from the liquid immersion cooling oil, converts the received heat into electrical energy, and sends the converted electrical energy to the first charging unit (122) and the second charging unit (132).

[0084] Here, the thermoelectric element (120) absorbs heat generated from the immersion cooling oil, thereby cooling the immersion cooling oil and increasing the additional cooling effect.

[0085] The second charging unit (132) charges the electrical energy sent from the thermoelectric element (120), and the first charging unit (122) charges the electrical energy sent from the thermoelectric element (120) and simultaneously sends the electrical energy (or voltage) to the control unit (110).

[0086] And the above control unit (110) sends a control signal to the cooling water flow motor (108).

[0087] The above cooling water flow motor (108) is driven according to a control signal from the control unit (110). As the cooling water flow motor (108) is driven, the impeller (130) rotates to draw in the liquid immersion cooling oil through the suction port (124) of the guide pipe (128) and discharges the drawn-in liquid immersion cooling oil through the discharge port (126) of the guide pipe (128) to generate a water flow. At this time, the liquid immersion cooling oil is cooled by the water flow.

[0088] When the cooling water flow motor (108) is driven as described above, the control unit (110) sends a control signal to the temperature measuring unit (112), the flow rate measuring unit (114), and the flow velocity measuring unit (116) after a certain period of time according to a preset program.

[0089] The above temperature measuring unit (112) measures the temperature of the liquid immersion cooling oil introduced into the receiving space according to the control signal of the control unit (110) and sends the measured temperature value to the control unit (110).

[0090] The control unit (110) compares the preset temperature value with the measured temperature value, and if the measured temperature value is higher than the preset temperature value, turns on the switch (134).

[0091] When the switch (134) is turned on, the second charging unit (120) sends electrical energy to the cooling water flow motor (108). At this time, the cooling water flow motor (108) receives electrical energy simultaneously from the first charging unit (120) and the second charging unit (120), so the driving speed increases and the rotation of the shaft increases.

[0092] As described above, when the shaft rotation of the cooling water flow motor (108) increases, the rotation of the impeller (130) connected to the shaft increases, and the impeller (130) rapidly sucks the liquid immersion cooling oil into the suction port (124) of the guide pipe (128) and discharges the sucked liquid immersion cooling oil into the discharge port (126) of the guide pipe (128) to generate a water flow. At this time, as the water flow is rapid, the liquid immersion cooling oil is rapidly cooled.

[0093] Therefore, the cooling effect of the immersion cooling oil is enhanced by the turbulence generated by the above-mentioned immersion cooling oil.

[0094] Meanwhile, the above flow rate measuring unit (114) measures the flow rate of the liquid immersion cooling oil introduced into the receiving space according to the control signal of the control unit (110) and sends the measured flow rate value to the control unit (110).

[0095] The control unit (110) compares the measured flow rate value with the preset flow rate value, and if the measured flow rate value is lower than the preset flow rate value (i.e., the temperature of the liquid immersion cooling oil is considered to be higher than the preset temperature value), it turns on the switch (134).

[0096] When the switch (134) is turned on, the second charging unit (120) sends electrical energy to the cooling water flow motor (108). At this time, the cooling water flow motor (108) receives electrical energy simultaneously from the first charging unit (120) and the second charging unit (120), so the driving speed increases and the rotation of the shaft increases.

[0097] As described above, when the shaft rotation of the cooling water flow motor (108) increases, the rotation of the impeller (130) connected to the shaft increases, and the impeller (130) rapidly sucks the liquid immersion cooling oil into the suction port (124) of the guide pipe (128) and discharges the sucked liquid immersion cooling oil into the discharge port (126) of the guide pipe (128) to generate a water flow. At this time, as the water flow is rapid, the liquid immersion cooling oil is rapidly cooled.

[0098] On the other hand, the above flow rate measuring unit (116) measures the flow rate of the liquid immersion cooling oil introduced into the receiving space according to the control signal of the control unit (110) and sends the measured flow rate value to the control unit (110).

[0099] The control unit (110) compares the preset flow rate value with the measured flow rate value, and if the measured flow rate value is lower than the preset flow rate value (i.e., the temperature of the liquid immersion cooling oil is considered to be higher than the preset temperature value), it turns on the switch (134).

[0100] When the switch (134) is turned on, the second charging unit (120) sends electrical energy to the cooling water flow motor (108). At this time, the cooling water flow motor (108) receives electrical energy simultaneously from the first charging unit (120) and the second charging unit (120), so the driving speed increases and the rotation of the shaft increases.

[0101] As described above, when the shaft rotation of the cooling water flow motor (108) increases, the rotation of the impeller (130) connected to the shaft increases, and the impeller (130) rapidly sucks the liquid immersion cooling oil into the suction port (124) of the guide pipe (128) and discharges the sucked liquid immersion cooling oil into the discharge port (126) of the guide pipe (128) to generate a water flow. At this time, as the water flow is rapid, the liquid immersion cooling oil is rapidly cooled.

[0102] Accordingly, the present invention is equipped with a cooling water flow motor driven by self-power using the heat of the immersion cooling oil, and by driving the cooling water flow motor, the circulation of the immersion cooling oil can be facilitated, thereby enhancing the cooling effect of the immersion cooling oil.

[0103] The detailed description of the invention above is merely illustrative of the invention and is used only for the purpose of explaining the invention, not to limit the meaning or the scope of the invention as defined in the claims.

[0104] Therefore, those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of the present invention should be determined by the technical concept of the appended claims.
