Description

Technical Field

[0001] The present invention relates to a cooling system and a cooling device, and more particularly to an immersion cooling system and a cooling device for cooling a server. Background Art

[0002] Immersion cooling is a type of liquid cooling technology. For example, the server is directly immersed in a non-conductive coolant. The heat energy generated by the server components is transferred to the coolant. The coolant with increased temperature is cooled by circulating cooling and then flows back to continue to absorb the heat energy of the server. Therefore, no other active cooling parts (such as fans) are required to cool the server, which helps to improve energy efficiency.

[0003] The traditional practice is to place multiple servers directly in a coolant tank, use a pump to push the flow of coolant, allow coolant with a lower temperature to enter the tank, and discharge the heated coolant in the tank for cooling, thereby achieving the purpose of cooling the server through heat exchange of the coolant. However, in the existing practice, regardless of the wattage of the heat generated by different servers, or whether the position of the server in the tank is close to the inlet and outlet of the hot and cold coolants, the server is directly placed in the tank, hoping that the heat generated by different servers can be cooled by the coolant in the tank to achieve the purpose of cooling. However, in actual situations, due to the different heat generation of different servers, or the different positions in the tank, or the different structures of the cooling liquid due to the server, the flow rate of the coolant fluid flowing through each server is different, resulting in inconsistent heat dissipation efficiency of each server, which may cause local overheating of the server and the risk of increasing pump power consumption.

[0004] Therefore, how to provide a cooling system that can adjust the heat dissipation performance of servers at different positions in the storage tank according to demand while avoiding the risk of increasing the pump power consumption due to local overheating of the server and thus increasing the flow rate of the coolant is a topic of great importance in the industry. Summary of the invention

[0005] In view of the above problems, the purpose of the present invention is to provide a cooling device and a cooling system, which can adjust the heat dissipation performance of servers at different positions in the storage tank according to needs, and at the same time avoid the problem of overheating of local hot spots in the server and the need to increase pump power consumption.

The adjustment structure is movably arranged in the receiving tank and has an adjustment plate whose position corresponds to the groove. The control mechanism is arranged in the receiving tank and connected to the adjustment structure, and the control mechanism is suitable for controlling the adjustment plate to move between a first position and a second position; wherein, when the adjustment plate moves from the first position to the second position, the adjustment plate passes through the groove into the liquid inlet space to separate the liquid inlet space into a first chamber corresponding to the first plate portion and a second chamber corresponding to the second plate portion.

[0007] To achieve the above-mentioned purpose, the present invention also proposes a cooling system, comprising at least two servers, a receiving tank, a spoiler, an adjustment structure and a control mechanism. The receiving tank is suitable for accommodating the servers and a coolant. The spoiler is arranged in the receiving tank to separate the receiving tank into a liquid inlet space and a cooling space, wherein the servers are located in the cooling space, wherein the spoiler comprises a groove, wherein the groove divides the spoiler into a first plate portion and a second plate portion opposite to each other, wherein the first plate portion and the second plate portion respectively have a plurality of connecting holes connected to the liquid inlet space and the cooling space. The adjustment structure is movably arranged in the receiving tank and has an adjustment plate whose position corresponds to the groove. The control mechanism is arranged in the receiving tank and connected to the adjustment structure, wherein the control mechanism is suitable for controlling the adjustment plate to move between a first position and a second position; wherein, when the adjustment plate moves from the first position to the second position, the adjustment plate passes through the groove into the liquid inlet space to separate the liquid inlet space into a first chamber corresponding to the first plate portion and a second chamber corresponding to the second plate portion.

[0008] In one embodiment, the accommodating tank has a liquid inlet pipeline and a confluence space connected to the liquid inlet pipeline, and the confluence space is communicated with the first chamber.

[0009] In one embodiment, the cooling device (cooling system) also includes a first baffle and a second baffle, which are respectively arranged in the first chamber and the second chamber and extend along the extension direction of the groove, and the thickness of the first baffle and the second baffle gradually increases in the direction away from the liquid inlet pipeline.

[0010] In one embodiment, the control mechanism includes a controller, and the adjustment structure also includes a connecting portion, wherein the two ends of the connecting portion are respectively connected to the controller and the adjustment plate, wherein the controller is fixed to a top of the accommodating groove and drives the adjustment plate to move between the first position and the second position through the connecting portion.

[0073] The following will refer to the relevant drawings to describe the cooling device and cooling system according to the embodiments of the present invention, wherein the same elements will be described with the same reference symbols. The various elements appearing in the following embodiments are only used to illustrate their relative relationships and do not represent the proportions or sizes of the actual elements.

[0074] Figure 1 is a three-dimensional schematic diagram of a cooling system 1 according to an embodiment of the present invention, Figure 2 and Figure 3 They are Figure 1 A partial three-dimensional schematic diagram of a cooling system 1, Figure 4 for Figure 1 A schematic diagram showing the relationship between the spoiler 12, the adjustment structure 13 and the control mechanism 14 of the cooling device 10 in the cooling system 1, Figure 5 for Figure 1 A partial three-dimensional schematic diagram of a cooling system 1, Fig. 6A for Figure 1 A cross-sectional schematic diagram of the cooling system 1 of the cooling device 10 when the adjustment plate 131 of the adjustment structure 13 is at the second position P2, Figure 6B for Fig. 6A An enlarged schematic diagram of the control mechanism 14, Figure 6C for Fig. 6A A partial enlarged schematic diagram of Fig.6D for Figure 1 A cross-sectional schematic diagram of a cooling system 1 in which the adjustment plate 131 of the adjustment structure 13 of the cooling device 10 is at the first position P1, Fig. 6E for Fig.6D The enlarged schematic diagram of the control mechanism 14 is shown in FIG. Fig. 6F for Fig.6D In order to clearly show the relative relationship between the components, Figure 2 , Figure 3 , Figure 6C and Fig. 6F Servers 2a and 2b are not shown. In addition, in order to clearly show the relative relationship between the adjustment structure 13 and the spoiler 12, Figure 3 , Figure 4The baffle 15 is not shown.

[0075] Please refer to Figures 1 to 5 The cooling system 1 includes a cooling device 10 and at least two servers 2a and 2b. The cooling device 10 includes a receiving tank 11, a spoiler 12, an adjustment structure 13 and a control mechanism 14. In addition, the cooling device 10 of this embodiment may also include a baffle 15. Here, the cooling device 10 is suitable for an immersion cooling system, and cooling two servers 2a and 2b is taken as an example, but it is not limited to this. In different embodiments, the cooling device 10 can also be used to cool three or more servers.

[0076] The receiving tank 11 is suitable for receiving the servers 2a, 2b and the cooling liquid, and has a liquid inlet pipe I and a liquid outlet pipe O. The relatively low-temperature non-conductive cooling liquid can enter the receiving tank 11 through the liquid inlet pipe I located at the lower side of the receiving tank 11 and pass through the servers 2a, 2b, and then leave through the liquid outlet pipe O located at the upper side, thereby taking away the heat generated by the servers 2a, 2b.

[0077] The spoiler 12 is disposed in the receiving tank 11 to divide the receiving tank 11 into a liquid inlet space S1 and a cooling space S2, and the servers 2a and 2b are located in the cooling space S2. Here, the liquid inlet pipeline I is connected to a confluence space S3 located in the receiving tank 11, and the confluence space S3 is connected to the liquid inlet space S1. Therefore, after the coolant enters a confluence space S3 through the liquid inlet pipeline I, it can enter the liquid inlet space S1 through the confluence space S3, and then enter the cooling space S2 through the spoiler 12 to cool the servers 2a and 2b.

[0078] The spoiler 12 includes a groove 121 ( Figure 4 ), the groove 121 divides the spoiler 12 into a first plate portion 122a and a second plate portion 122b opposite to each other, and the positions of the servers 2a and 2b correspond to the first plate portion 122a and the second plate portion 122b, respectively. In other words, the position of the server 2a in the cooling space S2 is located on the upper side of the first plate portion 122a, and the position of the server 2b in the cooling space S2 is located on the upper side of the second plate portion 122b. Here, the groove 121 extends along a direction D2 (extension direction), and the liquid inlet pipeline I and the first plate portion 122a are located on the same side of the groove 121, while the first plate portion 122a and the second plate portion 122b are located on opposite sides of the groove 121. The first plate portion 122a and the second plate portion 122b respectively have a plurality of connecting holes 123, so that the liquid inlet space S1 can be connected to the cooling space S2 through the connecting holes 123, so that the coolant can enter the cooling space S2 from the liquid inlet space S1 to cool the servers 2a and 2b.

[0079] The adjustment structure 13 is movably disposed in the receiving groove 11, and has an adjustment plate 131 disposed at a position corresponding to the groove 121. The adjustment plate 131 of this embodiment is located at the lower side of the adjustment structure 13, and can be regarded as a gate for controlling the flow direction of the coolant, and the position and size of the adjustment plate 131 correspond to the groove 121. When the adjustment structure 13 moves up and down along another direction D1 perpendicular to the direction D2, the adjustment plate 131 can pass through the groove 121.

[0080] The control mechanism 14 is disposed in the receiving groove 11 and connected to the adjustment structure 13, and the control mechanism 14 is suitable for controlling the adjustment plate 131 to move between a first position P1 and a second position P2. When the control mechanism 14 controls the adjustment plate 131 to move downward from the first position P1 to the second position P2 along the direction D1 ( Figure 5 , Fig. 6A ), the adjusting plate 131 can pass through the groove 121 and enter the liquid inlet space S1 to separate the liquid inlet space S1 into a first chamber S1a corresponding to the first plate portion 122a and a second chamber S1b corresponding to the second plate portion 122b. Conversely, when the control mechanism 14 controls the adjusting plate 131 to move upward from the second position P2 to the first position P1 along the direction D1 ( Fig.6D ), the first chamber S1a and the second chamber S1b will form a complete liquid inlet space S1 due to the departure of the adjustment plate 131.

[0081] For details, please refer to Figures 1 to 5 And cooperate 6A to 6F As shown, the control mechanism 14 has a controller 141, and the controller 141 is fixed to a top 111 of the receiving tank 11. In addition, the adjustment structure 13 further has a connecting portion 132, and the two ends of the connecting portion 132 are respectively connected to the controller 141 and the adjustment plate 131. Therefore, the controller 141 can adjust the position of the adjustment plate 131 through the connecting portion 132, so that the adjustment plate 131 moves between the first position P1 and the second position P2 along the direction D1. In this embodiment, the number of the connecting portion 132 and the controller 141 is two, that is, the adjustment structure 13 has two connecting portions 132, and the two connecting portions 132 and the two controllers 141 are correspondingly arranged on the two opposite inner side walls of the receiving tank 11, and the two connecting portions 132 are respectively connected to the two sides of the adjustment plate 131. Here, the two inner side walls of the receiving tank 11 are respectively provided with two fixed structures 17a and 17b, the server 2a is arranged between the two fixed structures 17a, and the server 2b is arranged between the two fixed structures 17b. In addition, each connecting portion 132 is sandwiched between the fixing structures 17a and 17b and can move up and down relative to the fixing structures 17a and 17b along the direction D1.

[0082] like Fig. 6AAs shown, the aforementioned second position P2 is the position when the adjustment structure 13 (adjustment plate 131) is downward (closed), so the first chamber S1a and the second chamber S1b are blocked by the adjustment plate 131. Since the liquid inlet pipeline I is connected to the first chamber S1a via the confluence space S3, the coolant entering the first chamber S1a through the liquid inlet pipeline I through the confluence space S3 cannot directly enter the second chamber S1b. The coolant can only enter the cooling space S2 through the connecting hole 123 of the first plate portion 122a to cool the server 2a. In addition, as Fig.6D As shown, the aforementioned first position P1 is the position when the adjustment structure 13 (adjustment plate 131) is upward (opened), and the coolant can immediately flow into the second chamber S1b after entering the first chamber S1a through the liquid inlet pipe I, and then enter the cooling space S2 through the connecting holes 123 of the first plate portion 122a and the second plate portion 122b to cool the servers 2a and 2b, and the higher temperature coolant flows out from the liquid outlet pipe O. After external heat exchange, the lower temperature coolant enters the containing tank 11 through the liquid inlet pipe I to carry out the next cooling cycle.

[0083] Please refer to Fig.6D The baffle 15 is located in the cooling space S2 and is arranged (fixed) on the spoiler 12 along the extension direction of the groove 121 (direction D2), and extends from one side of the groove 121 to the direction of the servers 2a and 2b (direction D1). Here, the highest point of the baffle 15 is lower than the bottom of the servers 2a and 2b. In addition, when the adjustment plate 131 is in the first position P1 (open position), the coolant flowing from the first chamber S1a to the second chamber S1b will move upward through the connecting hole 123 of the second plate portion 122b, that is, toward Fig.6D The baffle 15 can prevent the coolant on the left side of the cooling space S2 from quickly flowing back to the right side of the cooling space S2, thereby adjusting the flow direction of the coolant and preventing the coolant flowing to the server 2b through the connecting hole 123 of the second plate portion 122b from flowing back to the server 2a.

[0084] Please also refer to Figure 5 and Fig.6D, the cooling system 1 of the present embodiment may further include a first baffle 16a and a second baffle 16b, the first baffle 16a and the second baffle 16b are respectively disposed in the first chamber S1a and the second chamber S1b, and extend along the extension direction (direction D2) of the groove 121. Here, the first baffle 16a and the second baffle 16b are disposed at the inner bottom of the accommodating groove 11. In addition, the thickness of the first baffle 16a and the second baffle 16b gradually increases in the direction away from the liquid inlet pipeline I, that is, the height of the first baffle 16a away from the liquid inlet pipeline I is greater than the height of the side adjacent to the liquid inlet pipeline I, and the height of the second baffle 16b away from the liquid inlet pipeline I is greater than the height of the side adjacent to the liquid inlet pipeline I. Specifically, a cross-section of the first baffle 16a and the second baffle 16b of the present embodiment respectively forms a triangle ( Fig.6D ), and has the characteristics that the part adjacent to the liquid inlet pipeline I is lower and the part away from the liquid inlet pipeline I is higher. By this, in addition to concentrating the coolant to flow to the cooling space S2 on the upper side, the problem of coolant backflow from the liquid inlet pipeline I into the liquid inlet space S1 can also be avoided.

[0085] It should be noted that in the existing immersion cooling system, the storage tank is not provided with an adjustment structure (adjustment plate). Therefore, the coolant entering the liquid inlet space of the storage tank through the liquid inlet pipe will immediately flow to the space corresponding to the second chamber and then flow upward to cool the server, resulting in inconsistent heat dissipation performance of the servers on both sides (usually the cooling effect of the server corresponding to the second chamber is better), which will lead to the risk of local overheating of the server and the need to increase the power consumption of the pump.

[0086] However, in the cooling system 1 of the present embodiment, the flow direction of the coolant can be changed and the flow rate of the coolant from the first chamber S1a to the second chamber S1b can be adjusted by adjusting the position of the adjustment structure 13 (adjustment plate 131) through the control mechanism 14 (controller 141). That is, the flow rate of the coolant to the servers 2a and 2b (cooling space S2) can be adjusted according to the heat dissipation requirements of the servers 2a and 2b, so that the servers 2a and 2b can achieve better heat dissipation performance. At the same time, it can also avoid overheating of a local hot spot in a server, thereby increasing the pump power consumption problem caused by increasing the flow rate of the coolant.

[0087] The following specifically describes how to adjust the position of the adjustment structure 13 (adjustment plate 131) through the control mechanism 14. The adjustment of the adjustment structure 13 can be divided into manual adjustment or electric adjustment.

[0088] Take manual adjustment as an example, please refer to 6A to 6FAs shown, the controller 141 of this embodiment includes an adjustment rod 1411 perpendicular to the spoiler 12, and a matching piece 1412 corresponding to the adjustment rod 1411, and the matching piece 1412 is connected (fixed) to a bending area 1321 of the connecting portion 132. Here, the adjustment rod 1411 can be, for example, a screw and has a first end E1 and a second end E2 opposite to each other, and the matching piece 1412 can be, for example, a nut that cooperates (meets) with the screw. The first end E1 of the adjustment rod 1411 passes through the matching piece 1412 and the bending area 1321. When the adjustment rod 1411 is rotated, for example, when the second end E2 of the adjustment rod 1411 (screw) is rotated with a wrench, the mutual meshing action between the adjustment rod 1411 and the matching piece 1412 can drive the matching piece 1412 and the bending area 1321 (connecting portion 132) to move up or down along the direction D1 (for example, by Figure 6B become Fig. 6E ), thereby driving the adjustment plate 131 to move between the first position P1 and the second position P2, thereby adjusting the flow direction and flow rate of the coolant through the adjustment plate 131.

[0089] In addition, in order to allow the adjustment structure 13 to stably move along the direction D1, the controller 141 of this embodiment also includes a fixed seat 1413 and a guide member 1414. The fixed seat 1413 has a protrusion 1417 and a guide slot H extending in a direction perpendicular to the spoiler 12. The second end E2 of the adjustment rod 1411 passes through the protrusion 1417. The guide member 1414 is fixed to the connection portion 132 and is movably arranged in the guide slot H, so that the adjustment structure 13 is guided by the guide member 1414 and the guide slot H when moving up and down, and is more stable. Here, the guide member 1414 can be, for example, a screw used in combination with a locking member 1415 to ensure that the guide member 1414 can stably move up and down in the guide slot H and play the role of guiding the connection portion 132. In addition, in one embodiment, a scale can be provided on one side of the fixed seat 1413 (refer to Fig. 7A ), thereby knowing the opening height (or position) of the adjustment plate 131.

[0090] Fig. 7A for Fig.6D An enlarged schematic diagram of another embodiment of the control mechanism of Figure 7B for Fig. 7A Here, Fig. 7A and Figure 7B The control mechanism 14a is used as an example to adjust the regulating structure 13 in an electric manner.

[0091] like Fig. 7A and Figure 7BAs shown, the control mechanism 14a is substantially the same as the control mechanism 14 of the above-mentioned embodiment. The main difference from the control mechanism 14 is that the controller 141a of the control mechanism 14a of this embodiment may further include a driving member 1416 and a sensing unit 18 (electrically) connected to the driving member 1416. The driving member 1416 may include, for example but not limited to, a motor (and a transmission gear) to drive the second end E2 of the adjustment rod 1411 to rotate, thereby driving the adjustment plate 131 to move between the first position P1 and the second position P2.

[0092] The sensing unit 18 is suitable for sensing the temperature of the servers 2a and 2b. When the sensing unit 18 senses that the temperature of the server 2a corresponding to the first plate portion 122a is greater than the temperature of the server 2b corresponding to the second plate portion 122b, the driving member 1416 can drive the adjustment rod 1411 to rotate so that the adjustment plate 131 moves from the first position P1 to the second position P2, and the partition of the adjustment plate 131 is used to reduce the flow of the coolant flowing from the first chamber S1a to the second chamber S1b, thereby increasing the flow of the coolant flowing from the first chamber S1a to the server 2a and enhancing the heat dissipation effect of the server 2a. In one embodiment, the sensing unit 18 may include at least two temperature sensors respectively disposed on the servers 2a and 2b.

[0093] In addition, other technical features of the control mechanism 14a are the same as those of the control mechanism 14 and will not be further explained.

[0094] In summary, in the cooling device and cooling system of the present invention, the adjustment structure (adjustment plate) is controlled by the control mechanism to move between the first position and the second position; wherein, when the control mechanism controls the adjustment plate to move from the first position to the second position, the adjustment plate passes through the groove of the spoiler plate into the liquid inlet space, so as to divide the liquid inlet space into a first chamber and a second chamber corresponding to the first plate portion and the second plate portion of the spoiler, respectively. The structural design enables the cooling system of the present invention to change the flow direction of the coolant entering the accommodating tank and adjust the flow rate of the coolant entering the cooling space from the first chamber and the second chamber, thereby cooperating with the heat dissipation requirements of servers at different positions to achieve better heat dissipation performance, and also avoid overheating of local hot spots in the server, thereby avoiding the problem of increased pump power consumption caused by increasing the flow rate of the coolant.

[0095] The above description is for illustrative purposes only and is not intended to be limiting. Any equivalent modifications or changes made thereto without departing from the concept and scope of the present invention should be included in the claims.
