Description

Technical Field

[0001] The present invention relates to the technical field of server refrigeration, and specifically to a liquid cooling module and a liquid cooling server. Background Art

[0002] With the booming development of graphics processing unit computing, the actual business has higher and higher requirements for the computing power of the underlying hardware infrastructure. The improvement of server performance directly leads to an increase in server power consumption. At the same time, the process upgrade brings not only a leap in computing power, but also a significant increase in overall power consumption and heat generation. With the number of servers in a single cabinet remaining unchanged, the substantial increase in the power consumption of the entire cabinet poses a great challenge to the heat exchange in the data center. To address the above challenges, the cooling technology of servers also needs to be innovated. Traditional air cooling has gradually approached its limit. Facing servers with high integration, high power consumption, and high heat generation, liquid cooling technology can take away the heat generated inside the server through liquid circulation, and has the advantages of high heat dissipation efficiency, low noise, and high energy efficiency, and is widely used;

[0018] The beneficial effects of the present invention are:

[0019] 1. This liquid cooling module and liquid cooling server are provided with a temperature-controlled driving mechanism. The temperature-controlled driving mechanism can absorb the heat from the heating element to heat and expand the thermal expansion and contraction liquid inside it. After the thermal expansion and contraction liquid expands, it will use hydraulic pressure to squeeze the piston assembly outward. After the piston assembly is squeezed by the hydraulic pressure, it can drive the sawtooth plate to move to one side through the telescopic slide rod. During the movement of the sawtooth plate to one side, it can drive the flow regulating mechanism to rotate a certain angle, increase the flow of coolant flowing into the liquid cooling mechanism to accelerate cooling and heat dissipation. The higher the temperature on the heating element, the corresponding temperature inside the temperature-controlled driving mechanism. The greater the volume of the thermal expansion and contraction liquid is, the greater the rotation angle of the flow regulating mechanism under the drive of the serrated plate will be, and the flow rate of the coolant flowing into the liquid cooling mechanism can be increased according to the temperature of the surface of the heating element to speed up the cooling. On the contrary, when the temperature of the surface of the heating element that needs to be cooled is low, the volume of the thermal expansion and contraction liquid will be smaller due to heat expansion, and the flow regulating mechanism will be driven by the serrated plate to rotate and open at a smaller angle, and the flow rate of the coolant flowing into the liquid cooling mechanism will be smaller accordingly, so overcooling will not occur, and precise cooling can be performed according to the actual heating conditions of different heating elements.

[0020] 2. When the liquid cooling module and the liquid cooling server are installed and used, the refrigeration plate member and the heat exchange box are connected by a gravity heat pipe. The number, size and shape of the gravity heat pipes can be changed according to the installation space inside the chassis within the allowable range. The layout range and occupied space inside the chassis are small, and it is less restricted by the internal space of the chassis. By arranging an isolation guide plate member inside the heat exchange box of the liquid cooling mechanism, the isolation guide plate member can divide the inside of the heat exchange box into a serpentine structure, so that the condensate can flow in a serpentine shape inside the heat exchange box, which can increase the flow path of the condensate inside the heat exchange box and improve the heat exchange speed.

[0021] 3. When the liquid cooling mechanism is fixedly connected to the collector through the connecting component, the connecting component can press down and open the sealing component through the pressing pipe fitting at the bottom end. At this time, the collector is connected to the liquid cooling mechanism in a through manner. When it is necessary to repair or replace the liquid cooling mechanism and remove the liquid cooling mechanism from the top of the collector, the sealing component can automatically block the first threaded connection nozzle and the second threaded connection nozzle at the top end of the collector, which can not only prevent the coolant from leaking, but also will not affect the normal use of other liquid cooling mechanisms.

[0047] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for explaining and illustrating the present invention and are not used to limit the present invention.

[0048] Embodiment: As Figure 1-11 shown, a liquid cooling module includes a collector 1, a liquid inlet pipe 2 and a liquid outlet pipe 3 fixedly arranged on one side of the collector 1. Water pipe connectors 4 are fixedly arranged at the ends of the liquid inlet pipe 2 and the liquid outlet pipe 3. Flow rate adjusting mechanisms 5 are symmetrically arranged inside the collector 1. One end bottom of the flow rate adjusting mechanism 5 is meshed and connected with a temperature-controlled driving mechanism 6. A liquid cooling mechanism 7 is threadedly connected to the top of the collector 1. A sealing assembly 8 is fixedly arranged at the top of the inner cavity of the collector 1. When it is necessary to repair or replace the liquid cooling mechanism 7 and the liquid cooling mechanism 7 is removed from the top of the collector 1, the sealing assembly 8 can automatically block the top end of the collector 1, which can not only avoid the leakage of the coolant, but also does not affect the normal use of other liquid cooling mechanisms 7;

[0049] The temperature-controlled driving mechanism 6 includes a liquid storage tank 601 and a thermal expansion and contraction liquid 602 filled in the inner cavity of the liquid storage tank 601. A heat-conducting plate 603 is fixedly inserted at an equidistant distance on one side of the liquid storage tank 601. A heat-absorbing plate 604 is fixedly connected to one end of the heat-conducting plate 603. An extension pipe 605 is fixedly provided through one side of the liquid storage tank 601 away from the heat-conducting plate 603. A telescopic slide rod 606 is movably inserted at one end of the extension pipe 605. Piston assemblies 607 are fixedly connected to both ends of the telescopic slide rod 606. The serrated plate 608 is meshed with the flow regulating mechanism 5, and the telescopic slide rod 606 is inserted into the extension pipe 605. One end of the extension pipe 605 is sleeved with a return spring 609. The temperature-controlled driving mechanism 6 can absorb the heat from the heating element through the heat-conducting plate 603 and the heat-absorbing plate 604 on one side to heat and expand the heat-expanding and cold-contracting liquid 602 inside. After the heat-expanding and cold-contracting liquid 602 expands, it will squeeze the piston assembly 607 outwards by hydraulic pressure. The piston assembly 607 is subjected to the liquid After squeezing, the telescopic sliding rod 606 can drive the serrated plate 608 to move to one side. During the movement of the serrated plate 608 to one side, the flow regulating mechanism 5 can be driven to rotate a certain angle, and the flow rate of the coolant flowing into the liquid cooling mechanism 7 is increased to accelerate cooling and heat dissipation. The higher the temperature on the heating element, the larger the volume of the thermal expansion and contraction liquid 602 inside the corresponding temperature-controlled driving mechanism 6 will expand, and the larger the angle at which the flow regulating mechanism 5 rotates under the drive of the serrated plate 608 can be increased according to the temperature of the surface of the heating element to accelerate cooling. On the contrary, when the temperature of the surface of the heating element that needs to be cooled is low, the volume of the thermal expansion and contraction liquid 602 expanded by heat will be relatively small, and the flow regulating mechanism 5 is driven by the serrated plate 608 to rotate and open. The smaller the angle, the smaller the flow rate of the coolant flowing into the corresponding liquid cooling mechanism 7 will be, and overcooling will not occur. Accurate cooling can be performed according to the actual heating conditions of different heating elements.

[0050] Among them, the current collector 1 includes a current collector housing 101. Inside the current collector housing 101, a U-shaped liquid inlet channel 102 and a linear liquid outlet channel 103 are provided. Inside the cavity of the U-shaped liquid inlet channel 102, a flow rate regulating mechanism installation cavity 104 is provided. Symmetrically and fixedly provided above the flow rate regulating mechanism installation cavity 104 at the top of the current collector housing 101 are first threaded connection nozzles 105. At the top of the linear liquid outlet channel 103, a second threaded connection nozzle 106 is fixedly provided through and through. During use, the liquid inlet pipe 2 is connected through and through with the U-shaped liquid inlet channel 102, and the liquid outlet pipe 3 is connected through and through with the linear liquid outlet channel 103. After the coolant is introduced into the U-shaped liquid inlet channel 102 through the liquid inlet pipe 2, the coolant can flow into the liquid cooling mechanism 7 through the first threaded connection nozzle 105 at the top of the current collector 1 to cool and lower the temperature of the first heating element 11 and the second heating element 12. After cooling and temperature reduction, the coolant then flows back into the linear liquid outlet channel 103 from the second threaded connection nozzle 106 and finally is discharged from the liquid outlet pipe 3. Through a set of current collectors 1, the diversion and collection of the coolant can be realized, and the space utilization rate can be effectively improved.

[0051] Among them, the flow rate regulating mechanism 5 includes a rotating shaft rod 501 rotatably inserted through the front side of the current collector housing 101 through a bearing. At both ends of the rotating shaft rod 501, a linkage gear 502 and a cylindrical sealing valve core 503 are respectively fixed. A through port 504 is provided in the middle of the cylindrical sealing valve core 503. When the temperature on the surface of the heating element is relatively low and water cooling is not required for temperature reduction, the flow rate regulating mechanism 5 is in a closed state, and at this time, the coolant does not flow. When the temperature on the surface of the heating element gradually rises, the heating element heats and expands the thermal expansion and contraction liquid 602 through the heat on the surface. After the thermal expansion and contraction liquid 602 expands, it uses hydraulic pressure to extrude the piston assembly 607 outward. After being hydraulically extruded, the piston assembly 607 can drive the sawtooth plate 608 to move to one side through the telescopic slide rod 606. During the process of the sawtooth plate 608 moving to one side, it can drive the cylindrical sealing valve core 503 on the flow rate regulating mechanism 5 to rotate a certain angle in a linkage manner, gradually opening the flow rate regulating mechanism 5 and increasing the flow rate of the coolant flowing into the liquid cooling mechanism 7 to accelerate cooling and heat dissipation.

[0052] Among them, the size of the cylindrical sealing valve core 503 matches the size of the flow rate regulating mechanism installation cavity 104. The linkage gear 502 is meshed with the sawtooth plate 608. The meshing connection between the linkage gear 502 and the sawtooth plate 608 enables the cylindrical sealing valve core 503 on the flow rate regulating mechanism 5 to rotate a certain angle in a linkage manner during the movement of the sawtooth plate 608.

[0053] Among them, the liquid cooling mechanism 7 includes a heat exchange box 701. Symmetrically fixed on the outer side of the heat exchange box 701 are fixed ears 702. Threaded fixing rods 703 are inserted through the fixed ears 702. Equally spaced and fixed on the bottom of the heat exchange box 701 are gravity heat pipes 704. Fixed to the bottom ends of the gravity heat pipes 704 are refrigeration plate parts 705. Fixed to one side of the heat exchange box 701 are a water inlet pipe 706 and a water return pipe 707. Fixed to one end of the water inlet pipe 706 and one end of the water return pipe 707 are connection components 708. The heat exchange box 701 can be fixedly installed through the threaded fixing rods 703. After the liquid cooling mechanism 7 is installed, the refrigeration plate part 705 on it adheres to the surface of the first heating element 11 or the second heating element 12 that needs to dissipate heat and cool down. The refrigeration plate part 705 can exchange heat with the coolant circulating in the heat exchange box 701 through the gravity heat pipes 704, dissipating heat and cooling down the first heating element 11 and the second heating element 12.

[0054] The top ends of the gravity heat pipes 704 penetrate into the interior of the heat exchange box 701, and equally spaced and fixed on the outer sides of the top ends of the gravity heat pipes 704 are heat exchange fins 709. The refrigeration plate part 705 is connected to the heat exchange box 701 through the gravity heat pipes 704. The quantity, size, and shape of the gravity heat pipes 704 can be changed according to the installation space inside the chassis 9 within the allowable range. Their layout range and occupied space inside the chassis 9 are small, and they are less restricted by the internal space of the chassis 9.

[0055] Among them, an isolation and diversion plate part 710 is fixedly installed in the inner cavity of the heat exchange box 701. The isolation and diversion plate part 710 divides the interior of the heat exchange box 701 into a serpentine structure. By arranging the isolation and diversion plate part 710 inside the heat exchange box 701, the isolation and diversion plate part 710 can divide the interior of the heat exchange box 701 into a serpentine structure, enabling the condensate to flow in a serpentine shape inside the heat exchange box 701, increasing the flow path of the condensate inside the heat exchange box 701 and improving the heat exchange speed.

[0056] Among them, the connection component 708 includes a threaded connection sleeve 7081 that is rotatably sleeved on one end of the water inlet pipe 706 and one end of the water return pipe 707 through bearings, and the size of the threaded connection sleeve 7081 matches the sizes of the first threaded connection nozzle 105 and the second threaded connection nozzle 106. A pressing pipe fitting 7082 is fixedly arranged in the middle of the threaded connection sleeve 7081, and the top end of the pressing pipe fitting 7082 is connected to the water inlet pipe 706 and the water return pipe 707 in a through manner. An inlet through hole 7083 is opened on the outer side of the bottom end of the pressing pipe fitting 7082. When the liquid cooling mechanism 7 is fixedly connected to the header 1 through the connection component 708, the connection component 708 can press down and open the sealing component 8 through the pressing pipe fitting 7082 at the bottom end. At this time, the header 1 and the liquid cooling mechanism 7 are connected in a through manner. When it is necessary to repair or replace the liquid cooling mechanism 7 and the liquid cooling mechanism 7 is removed from the top of the header 1, the sealing component 8 can automatically block the first threaded connection nozzle 105 and the second threaded connection nozzle 106 at the top end of the header 1, which can not only prevent the coolant from leaking, but also does not affect the normal use of other liquid cooling mechanisms 7.

[0057] Among them, the sealing component 8 includes a spring member 801 fixedly arranged at the top of the inner cavity of the header 1. The bottom end of the spring member 801 is fixedly connected with a sealing plug 802, and the size of the sealing plug 802 matches the sizes of the first threaded connection nozzle 105 and the second threaded connection nozzle 106. The first threaded connection nozzle 105 and the second threaded connection nozzle 106 at the top end of the header 1 can be automatically blocked through the sealing component 8.

[0058] Among them, the thermo - expansion liquid 602 uses kerosene. Insulating heat - conducting silica gels are provided at the bottom end of the liquid cooling mechanism 7 and the end of the temperature - controlled driving mechanism 6 far from the header 1. The melting point of kerosene is - 50°C and the boiling point is 80°C, which has good heat - expansion performance. The insulating heat - conducting silica gel can improve the heat - conducting performance between the liquid cooling mechanism 7, the first heating element 11, the second heating element 12 and between the temperature - controlled driving mechanism 6, the first heating element 11, the second heating element 12.

[0059] A liquid - cooled server includes a chassis 9 and a liquid - cooling module as described in any one of claims 1 - 9. It is characterized in that the liquid - cooling module is fixedly installed inside the chassis 9. A circuit board 10 is fixedly installed in the inner cavity of the chassis 9 through screws. A first heating element 11 and a second heating element 12 are fixedly installed on the top of the circuit board 10. Connection pillars 13 with threaded holes are fixedly arranged around the first heating element 11 and around the second heating element 12. The connection pillars 13 match the threaded fixing rods 703 on the liquid cooling mechanism 7. The liquid cooling mechanism 7 can be fixedly installed through the connection pillars 13 and the threaded fixing rods 703.

[0060] During operation, the liquid inlet pipe 2 is connected with the U-shaped liquid inlet channel 102, and the liquid outlet pipe 3 is connected with the straight liquid outlet channel 103. After the coolant is introduced into the U-shaped liquid inlet channel 102 through the liquid inlet pipe 2, the coolant can flow into the liquid cooling mechanism 7 through the first threaded connection nozzle 105 at the top of the collector 1 to cool the first heating element 11 and the second heating element 12. After cooling and cooling, the coolant flows back from the second threaded connection nozzle 106 to the straight liquid outlet channel 103, and is finally discharged from the liquid outlet pipe 3.

[0061] The temperature-controlled driving mechanism 6 can absorb the heat on the heating element through the heat-conducting plate 603 and the heat-absorbing plate 604 on one side to heat and expand the thermal expansion and contraction liquid 602 inside it. After the thermal expansion and contraction liquid 602 expands, it will use hydraulic pressure to squeeze the piston assembly 607 outward. After the piston assembly 607 is squeezed by the hydraulic pressure, it can drive the serrated plate 608 to move to one side through the telescopic slide rod 606. During the movement of the serrated plate 608 to one side, it can drive the flow regulating mechanism 5 to rotate a certain angle, increase the flow rate of the coolant flowing into the liquid cooling mechanism 7 to accelerate cooling and heat dissipation. The higher the temperature on the heating element, the corresponding temperature inside the temperature-controlled driving mechanism 6 The larger the volume of the thermal expansion and contraction liquid 602 expands, the larger the rotation angle of the flow regulating mechanism 5 driven by the sawtooth plate 608 is, and the flow rate of the coolant flowing into the liquid cooling mechanism 7 can be increased according to the temperature of the surface of the heating element to accelerate the cooling. On the contrary, when the temperature of the surface of the heating element to be cooled is low, the volume of the thermal expansion and contraction liquid 602 will be smaller due to the heat expansion, and the smaller the rotation opening angle of the flow regulating mechanism 5 driven by the sawtooth plate 608 is, the smaller the flow rate of the coolant flowing into the liquid cooling mechanism 7 is, and the overcooling phenomenon will not occur. Accurate cooling can be performed according to the actual heating conditions of different heating elements.

[0062] When the liquid cooling mechanism 7 is fixedly connected to the collector 1 through the connecting component 708, the connecting component 708 can press downward to open the sealing component 8 through the pressing tube 7082 at the bottom. At this time, the collector 1 and the liquid cooling mechanism 7 are through-connected. When the liquid cooling mechanism 7 needs to be inspected or replaced and the liquid cooling mechanism 7 is removed from the top of the collector 1, the sealing component 8 can automatically seal the first threaded connection nozzle 105 and the second threaded connection nozzle 106 at the top of the collector 1, which can not only prevent the leakage of the coolant, but also will not affect the normal use of other liquid cooling mechanisms 7.

[0063] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention.
