Description

Technical Field

[0001] The present application relates to the technical field of cooling equipment, and in particular to a cooling device with uniform flow of coolant. Background Art

[0002] With the rapid development of server technology, the heat dissipation problem caused by high-performance computing and high-density storage has become increasingly prominent. Oil cooling technology has been initially applied in the field of server heat dissipation due to its efficient heat dissipation performance and has the potential to replace water cooling technology.

[0003] During the oil cooling process, the cooling oil needs to be recovered and reused. However, most equipment allows the cooling oil to flow directly between the equipment and the recovery pipe after using the cooling oil. However, during the recovery flow of the cooling oil, a large number of bubbles will be mixed into the cooling oil after the cooling oil comes into contact with the air, which will lead to a decrease in the cooling and heat dissipation effect during the subsequent use of the cooling oil, affecting the performance of the cooling device. Summary of the invention

[0004] In order to improve the convenience of a cooling device with uniform flow of coolant during operation, the present application provides a cooling device with uniform flow of coolant.

[0005] The present application provides a cooling device with uniform coolant flow, which adopts the following technical solution: A cooling device for uniform flow of coolant, comprising a support frame, a heat sink box being mounted on the support frame, a transport component for filling the heat sink box with coolant being connected to the support frame, a flow guide component for controlling the flow of coolant being mounted in the heat sink box, an oil drain component for diverting the coolant being connected to the heat sink box, the oil drain component comprising an oil drain tank, the oil drain tank being mounted on the support frame, a first buffer plate and one or more second buffer plates being mounted in the oil drain tank, the first buffer plate being arranged above the second buffer plate, the oil drain tank located on the upper side of the first buffer plate being connected to the heat sink, an oil drain pipe being connected to the oil drain tank, and the connecting position between the oil drain pipe and the oil drain tank is located below the second buffer plate.

[0006] By adopting the above technical solution, the server chassis is placed in the heat sink, and the transport component sends the cooling oil into the heat sink. The flow of the cooling oil is controlled by the guide component so that the cooling oil can be evenly filled in the heat sink, ensuring uniform heat dissipation of the server chassis by the cooling oil. After passing through the server chassis, the cooling oil will flow into the oil drain tank, and the cooling oil will be buffered by the first buffer plate and the second buffer plate, so that the cooling oil can finally fall down evenly on the second buffer plate, which is convenient for uniform recovery of the cooling oil. The cooling oil is recovered at a uniform speed and the height of the cooling oil drop is reduced to prevent the cooling oil from contacting with the air to generate bubbles, thereby affecting the subsequent cooling effect on the server chassis.

[0007] In a specific feasible implementation scheme, a third oil outlet hole is opened on the second buffer plate, and the third oil outlet hole is arranged along the length direction of the second buffer plate. The aperture of the third oil outlet hole close to the connection position between the oil drain pipe and the oil drain tank is the smallest, and the aperture of the third oil outlet hole away from the connection position between the oil drain pipe and the oil drain tank tends to gradually increase.

[0008] By adopting the above technical scheme, because the cooling oil flows out from the oil drain pipe, the coolant flow rate near the oil drain pipe is larger, and the cooling oil falling from the third oil outlet hole near the oil drain pipe will be discharged from the oil drain tank in priority to the cooling oil falling from the third oil outlet hole far away from the oil drain pipe, which will cause the flow speed of the cooling oil far away from the oil drain pipe to slow down and cannot be discharged in time. By changing the size of the aperture of the third oil outlet hole, the speed of the cooling oil flowing down from the second buffer plate near the oil drain pipe is reduced, and the speed of the cooling oil leaving the second buffer plate far away from the oil drain pipe is increased, so that the cooling oil can flow quickly to the oil drain pipe in the oil drain tank, which is convenient for uniform recovery of the cooling oil.

[0009] In a specific possible implementation scheme, the flow guide component includes a diverter cover, which is installed at the bottom of the heat sink, and a diverter hole is provided on the diverter cover. A support plate is installed on the heat sink, and the support plate is arranged above the diverter cover. A first oil hole is provided on the support plate. The transport component is connected to the heat sink, and the oil outlet position is located below the diverter cover.

[0010] By adopting the above technical solution, when the cooling oil flows into the heat sink from the second connecting pipe, the cooling oil content near the connecting position between the second connecting pipe and the heat sink is larger and the flow speed is faster. The aperture of the diverter hole near the connecting position between the second connecting pipe and the heat sink is reduced to prevent a large amount of cooling oil from flowing out of the diverter hole near the connecting position, so as to facilitate the cooling oil to flow to the two ends of the heat sink in the diverter cover, thereby ensuring that the cooling oil can be evenly and quickly filled in the heat sink.

[0011] In a specific implementation manner, the diverter hole has the smallest aperture near the oil outlet where the transport component is connected to the heat dissipation box, and the aperture of the diverter hole away from the oil outlet gradually increases and then gradually decreases.

[0012] By adopting the above technical solution, after the cooling oil enters the heat sink, it is guided to both sides of the length direction of the heat sink through the diverter cover. After the cooling oil flows into the diverter cover, it flows out from the diverter hole to the width direction of the heat sink, which facilitates the cooling oil to be quickly filled into the heat sink.

[0013] In a specific possible implementation manner, a blocking plate for blocking the coolant is installed on the diverter cover, and the blocking plate is arranged on a side of the diverter hole away from the oil outlet position.

[0014] By adopting the above technical solution, since the cooling oil still tends to flow to both sides of the length direction of the diversion cover when flowing out of the diversion hole, the cooling oil is blocked by the blocking plate so that the cooling oil can be quickly filled to both sides of the width direction of the heat sink.

[0015] In a specific feasible implementation scheme, a second oil hole is provided on the support plate, the second oil hole is arranged directly above the diverter cover, the first oil hole is arranged close to the side wall of the heat dissipation box relative to the second oil hole, and the aperture of the second oil hole is larger than the aperture of the first oil hole.

[0016] By adopting the above technical scheme, when the cooling oil flows to the two side walls in the width direction of the heat sink, it will be blocked by the side walls of the heat sink. Because the cooling oil continuously flows out from the diverter hole, it is easy to cause the cooling oil level at the side walls on both sides of the heat sink to be higher than the cooling oil level at the diverter hole, so that the amount of oil at the side walls on both sides of the heat sink is relatively large, and the aperture of the first oil hole is smaller than the aperture of the second oil hole, so that the rising oil output near the side walls on both sides of the heat sink on the support plate is reduced, which is convenient for the cooling oil to flow to the top of the diverter cover and out of the second oil hole, so that the cooling oil can rise at a uniform speed from the bottom of the support plate to the top of the support plate to cool the server chassis, which is beneficial to improving the cooling effect.

[0017] In a specific feasible implementation scheme, a buffer assembly for controlling the flow rate of cooling oil is connected to the diverter hood, and the buffer assembly includes a first connecting platform, which is installed on the diverter hood, a first rack is slidably installed on the first connecting platform, a connecting plate is installed on the first rack, a first spring is installed on the first rack, one end of the first spring is connected to the connecting plate, and the other end is connected to the first connecting platform, and the first rack is connected to a baffle for slowing down the flow rate of cooling oil.

[0018] By adopting the above technical solution, when cooling oil begins to be filled into the cooling box or the flow rate of cooling oil in the cooling box needs to be accelerated to increase the oil filling speed, the cooling oil will rush onto the baffle after entering the diverter cover and will be decelerated by the baffle. The baffle pushes the first rack to move, and the movement of the first rack drives the connecting plate to compress the first spring. Through the first spring, the baffle can perform elastic buffering according to the flow rate of the cooling oil.

[0019] In a specific feasible implementation scheme, a second connecting platform is installed on the diversion cover, a rotating rod is rotatably installed on the second connecting platform, a first gear is connected to the rotating rod, the first gear is meshingly connected with the first rack, and the second gear is connected to the first rotating rod; a guide rail is installed on the blocking plate, a second rack is slidably installed on the guide rail, the second rack is meshingly connected with the second gear at one end close to the second gear, and a movable plate is connected to one end of the second rack away from the second gear.

[0020] By adopting the above technical solution, when the baffle drives the first rack to move, the first rack pushes the first gear to rotate, and the rotation of the first gear drives the second gear to rotate through the rotating rod. The second gear controls the second rack to slide on the guide rail. The second rack pushes the movable plate to move to increase the area of ​​the baffle plate, thereby enhancing the buffering effect of the baffle plate on the cooling oil, making it easier for the cooling oil to be quickly and evenly filled into the cooling box.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. Place the server chassis in the heat sink, and the transport component delivers the cooling oil to the heat sink. The flow of the cooling oil is controlled by the guide component so that the cooling oil can be evenly filled in the heat sink to ensure uniform heat dissipation of the server chassis by the cooling oil. After passing through the server chassis, the cooling oil will flow into the oil drain tank, and the cooling oil will be buffered by the first buffer plate and the second buffer plate, so that the cooling oil can finally fall down evenly on the second buffer plate, which is convenient for uniform recovery of the cooling oil. The cooling oil is recovered at a uniform speed and the height of the cooling oil drop is reduced to prevent the cooling oil from contacting with the air to generate bubbles, which affects the subsequent cooling effect on the server chassis.

[0022] 2. Through the setting of the buffer component, when the cooling oil starts to be filled into the cooling box or the circulation of the cooling oil in the cooling box needs to be accelerated to increase the oil filling speed, the cooling oil will rush onto the baffle after entering the diverter cover and will be decelerated by the baffle. The baffle pushes the first rack to move, and the movement of the first rack drives the connecting plate to compress the first spring. Through the first spring, the baffle can perform elastic buffering according to the flow rate of the cooling oil. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-9 This application is described in further detail.

[0033] Example: The present application discloses a cooling device for uniformly distributing cooling liquid, referring to Figure 1 and Figure 2 , including a support frame 1, a heat sink 2 is fixedly installed on the support frame 1, a transportation component 3 for delivering cooling oil to the heat sink 2 is installed on the support frame 1, a guide component 4 for controlling the uniform flow of the cooling oil is installed on the heat sink 2, and the heat sink 2 is connected to an oil discharge component 5 for recovering the cooling oil.

[0034] The transport component 3 delivers the cooling oil into the heat sink 2, and the guide component 4 guides the cooling oil so that the cooling oil is evenly filled in the heat sink 2. After the cooling oil absorbs the heat of the server chassis in the heat sink 2, it is finally refluxed and recovered through the oil discharge component 5 to prevent the heated cooling oil from staying in the heat sink 2 and affecting the heat dissipation effect.

[0035] The transport component 3 includes a first connecting tube 31, which is fixedly mounted on the support bracket 1 and arranged below the heat sink 2. One end of the first connecting tube 31 located below the heat sink 2 is fixedly connected to the second connecting tube 32. The first connecting tube 31 is connected to the middle position of the second connecting tube 32. The first connecting tube 31 is arranged along the length direction of the heat sink 2, and both ends of the first connecting tube 31 are connected to the heat sink 2.

[0036] The cooling oil flows from the first connecting pipe 31 into the second connecting pipe 32 and is divided through the second connecting pipe 32. The cooling oil enters the heat sink 2 from both ends respectively, which helps to speed up the speed at which the cooling oil enters the heat sink 2 and facilitates the cooling oil to be quickly filled into the heat sink 2.

[0037] Reference Figure 2 and Figure 3 The flow guide assembly 4 includes a flow diverter cover 41, which is fixedly mounted on the bottom of the heat sink 2. The flow diverter cover 41 is arranged along the length direction of the heat sink 2. The oil outlet position where the second connecting pipe 32 is connected to the heat sink 2 is located below the flow diverter cover 41. The side walls on both sides of the flow diverter cover 41 are provided with flow diverter holes 411. The aperture of the flow diverter hole 411 close to the connecting position between the second connecting pipe 32 and the heat sink 2 is the smallest. The aperture of the flow diverter hole 411 away from the connecting position between the second connecting pipe 32 and the heat sink 2 shows a trend of gradually increasing and then gradually decreasing. A blocking plate 42 is fixedly mounted at the position of each flow diverter hole 411 on the flow diverter cover 41. The blocking plate 42 is arranged on the side of the flow diverter hole 411 away from the connecting position between the second connecting pipe 32 and the heat sink 2.

[0038] Reference Figure 4 and Figure 5 A supporting plate 43 for placing the server chassis is fixedly installed on the heat dissipation box 2. The supporting plate 43 is arranged above the diverter cover 41 and has a distance from the diverter cover 41. A first oil hole 431 and a second oil hole 432 are opened on the supporting plate 43. The second oil hole 432 is arranged just above the diverter cover 41, and the aperture size of the second oil hole 432 is larger than the aperture size of the first oil hole 431.

[0039] Reference Figure 3 , Figure 4 and Figure 5After the cooling oil enters the heat sink 2, it is guided to both sides of the length direction of the heat sink 2 through the diverter cover 41. When the cooling oil flows into the heat sink 2 from the second connecting pipe 32, the cooling oil content near the connecting position between the second connecting pipe 32 and the heat sink 2 is large and the flow speed is fast. The aperture of the diverter hole 411 near the connecting position between the second connecting pipe 32 and the heat sink 2 is reduced to prevent a large amount of cooling oil from flowing out of the diverter hole 411 near the connecting position, so that the cooling oil can flow to both ends of the heat sink 2 in the diverter cover 41, ensuring that the cooling oil can be evenly and quickly filled in the heat sink 2. After the cooling oil flows into the diverter cover 41, it flows out from the diverter hole 411 and flows in the width direction of the heat sink 2. Because the cooling oil still has a tendency to flow to both sides of the length direction of the diverter cover 41 when flowing out of the diverter hole 411, the cooling oil is blocked by the blocking plate 42 so that the cooling oil can be quickly filled to both sides of the width direction of the heat sink 2.

[0040] When the cooling oil flows toward the two side walls of the heat sink 2 in the width direction, it will be blocked by the side walls of the heat sink 2. Because the cooling oil continuously flows out from the diverter hole 411, it is easy to cause the cooling oil level at the side walls of the heat sink 2 on both sides to be higher than the cooling oil level at the diverter hole 411, so that the oil volume at the side walls of the heat sink 2 on both sides is relatively large. The aperture of the first oil hole 431 is smaller than the aperture of the second oil hole 432, so that the rising oil volume on the supporting plate 43 close to the side walls of the heat sink 2 on both sides is reduced, which is convenient for cooling. The oil flows toward the top of the diverter cover 41 and flows out from the second oil hole 432, so that the cooling oil can rise uniformly from the bottom of the supporting plate 43 to the top of the supporting plate 43. The uniformly rising liquid level of the coolant can evenly take away the heat on the server chassis when slowly passing through the server chassis, thereby cooling the server chassis as a whole and preventing the cooling oil from flowing through part of the server chassis, resulting in the overall temperature of the server chassis not being uniform. The rising liquid level uniformly absorbs the heat of the server chassis, which is beneficial to improving the cooling effect.

[0041] Reference Figure 7 and Figure 8 A buffer assembly 45 for controlling the flow rate of cooling oil is connected to the flow divider 41. The buffer assembly 45 includes a first connecting platform 451, which is fixedly mounted on the flow divider 41. A first rack 452 is slidably mounted on the first connecting platform 451, a connecting plate 453 is fixedly mounted on the first rack 452, a first spring 454 is sleeved on the first rack 452, one end of the first spring 454 is fixedly connected to the connecting plate 453, and the other end is fixedly connected to the first connecting platform 451. A baffle 455 for slowing down the flow rate of cooling oil is fixedly connected to the first rack 452.

[0042] A second connecting platform 461 is fixedly mounted on the flow divider 41, a rotating rod 462 is rotatably mounted on the second connecting platform 461, a first gear 463 is fixedly mounted on the rotating rod 462, the first gear 463 is meshedly connected with the first rack 452, and a second gear 464 is fixedly connected to the rotating rod 462. A guide rail 465 is fixedly mounted on the blocking plate 42, a second rack 466 is slidably mounted on the guide rail 465, one end of the second rack 466 close to the second gear 464 is meshedly connected with the second gear 464, and one end of the second rack 466 away from the second gear 464 is fixedly connected to a movable plate 467.

[0043] When cooling oil starts to be filled into the heat sink 2 or the flow rate of cooling oil in the heat sink 2 needs to be accelerated to increase the oil filling speed, the cooling oil will hit the baffle 455 after entering the diverter cover 41, and will be decelerated by the baffle 455. The baffle 455 pushes the first rack 452 to move, and the movement of the first rack 452 drives the connecting plate 453 to compress the first spring 454. Through the first spring 454, the baffle 455 can perform elastic buffering according to the flow rate of the cooling oil.

[0044] When the baffle 455 drives the first rack 452 to move, the first rack 452 pushes the first gear 463 to rotate, and the rotation of the first gear 463 drives the second gear 464 to rotate through the rotating rod 462. The second gear 464 controls the second rack 466 to slide on the guide rail 465. The second rack 466 pushes the movable plate 467 to move to increase the area of ​​the baffle plate 42, thereby enhancing the buffering effect of the baffle plate 42 on the cooling oil, which is convenient for the cooling oil to be quickly and evenly filled into the heat sink 2.

[0045] Reference Figure 1 , Figure 8 and Fig. 9 The oil drain assembly 5 includes an oil drain box 51, which is fixedly mounted on the support frame 1. A first buffer plate 52 and a second buffer plate 53 are fixedly mounted on the oil drain box 51. The first buffer plate 52 is located above the second buffer plate 53. The first buffer plate 52 and the second buffer plate 53 divide the oil drain box 51 into three parts. The part of the oil drain box 51 located above the first buffer plate 52 is connected to the inside of the heat sink 2, and the part of the oil drain box 51 located below the second buffer plate 53 is connected to an oil drain pipe 54.

[0046] The first buffer plate 52 is provided with a first oil passage groove 521, which is a long waist-shaped through groove. The second buffer plate 53 is provided with a third oil outlet hole 531, which is arranged along the length direction of the second buffer plate 53. The third oil outlet hole 531 close to the connection position between the oil drain pipe 54 and the oil drain tank 51 has the smallest aperture, and the aperture of the third oil outlet hole 531 far from the connection position between the oil drain pipe 54 and the oil drain tank 51 tends to gradually increase.

[0047] After the cooling oil cools down the server chassis, the cooling oil will remain in the oil drain tank 51. After entering the oil drain tank 51, the cooling oil will preferentially fall on the first buffer plate 52. After the cooling oil is buffered by the first buffer plate 52, the cooling oil will fall from the first oil groove 521 on the first buffer plate 52 to the second buffer plate 53. Because the cooling oil flows out from the oil drain pipe 54, the coolant flow rate near the oil drain pipe 54 is larger, and the cooling oil falling from the third oil outlet hole 531 near the oil drain pipe 54 will be discharged from the oil drain tank 51 preferentially over the cooling oil falling from the third oil outlet hole 531 far from the oil drain pipe 54, which will cause the cooling oil far from the oil drain pipe 54 to flow out of the oil drain tank 51. 4 and cannot be discharged in time, by changing the size of the third oil outlet hole 531, the speed of the cooling oil flowing down from the second buffer plate 53 near the oil drain pipe 54 is reduced, and the speed of the cooling oil leaving the second buffer plate 53 away from the oil drain pipe 54 is increased, so that the cooling oil can flow quickly from the oil drain box 51 to the oil drain pipe 54, which is convenient for uniform recovery of the cooling oil, and the cooling oil is respectively received by the first buffer plate 52 and the second buffer plate 53 to prevent bubbles from being easily mixed in the cooling oil due to the large height when the cooling oil falls from the heat sink 2, thereby affecting the subsequent heat dissipation effect of the cooling oil.

[0048] The implementation principle of the embodiment of the present application is as follows: the transport component 3 delivers the cooling oil into the heat sink 2, and the guide component 4 guides the cooling oil so that the cooling oil is evenly filled in the heat sink 2. After the cooling oil absorbs the heat of the server chassis in the heat sink 2, the cooling oil is finally received by the first buffer plate 52 and the second buffer plate 53 respectively, to prevent the cooling oil from being mixed with bubbles when falling from the heat sink 2 due to its large height, thereby affecting the subsequent heat dissipation effect of the cooling oil.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
