Description

Technical Field

[0001] The present application relates to the technical field of flow regulation, and in particular to a flow regulation device, a cooling system and a cabinet. Background Art

[0002] With the development of technology in the computer field, the integration of data centers is getting higher and higher, and the heat generated by data centers during operation is getting higher and higher, resulting in higher and higher demand for heat dissipation in data centers. When data centers use liquid cooling for heat dissipation, if a single motor is used to adjust the flow of multiple liquid cooling pipes at the same time, only the synchronous adjustment of multiple liquid cooling pipes can be achieved. Different equipment in the data center generates different amounts of heat, and synchronously adjusting the flow of the liquid cooling pipes will increase energy consumption; if multiple motors are used to adjust the flow of multiple liquid cooling pipes separately, the increase in the number of motors not only leads to an increase in the volume occupied, but also increases the cost. Summary of the invention

[0003] The present application provides a flow regulating device, a cooling system and a cabinet which are small in size and can perform synchronous and asynchronous regulation on multiple valve bodies.

[0004] In a first aspect, the present application provides a flow regulating device, which includes a coupling, a first valve body assembly and a second valve body assembly, wherein the coupling is rotatable; the first valve body assembly has a first coupling state and a first decoupling state, the first valve body assembly includes a first drive disk module and a first valve body, the first drive disk module and the coupling are relatively fixed in the circumferential direction of the coupling, in the first coupling state, the first drive disk module is coupled to the first valve body so that the coupling drives the first valve body to rotate, and in the first decoupling state, the first drive disk module is decoupled from the first valve body; the second valve body assembly has a second coupling state and a second decoupling state, the second valve body assembly includes a second drive disk module and a second valve body, the second drive disk module and the coupling are relatively fixed in the circumferential direction of the coupling, in the second coupling state, the second drive disk module is coupled to the second valve body so that the coupling drives the second valve body to rotate, and in the second decoupling state, the second drive disk module is decoupled from the second valve body.

[0005] Wherein, the flow regulating device is used to regulate the flow of the fluid in the first pipeline and the second pipeline.

[0006] The first drive disk module and the second drive disk module are both fixed on the connecting shaft, and the connecting shaft can drive the first drive disk module and the second drive disk module to rotate when rotating, and the rotation speed of the first drive disk module and the second drive disk module is equal to or approximately equal to the rotation speed of the connecting shaft. In one embodiment, the connecting shaft is fixed to the output shaft of the first motor, and the first motor drives the connecting shaft to rotate. In one embodiment, the first drive disk module and the second drive disk module are arranged at intervals, and in other embodiments, the first drive disk module and the second drive disk module can also be arranged in contact. In one embodiment, the first drive disk module and the second drive disk module are annular and are sleeved on the outer circumference of the connecting shaft. In one embodiment, the first drive disk module and the second drive disk module can also be block-shaped.

[0007] The first valve body assembly can switch between a first coupling state and a first decoupling state. In the first coupling state, the first drive disk module rotates to drive the first valve body to rotate. The first valve body is located in the first pipeline. The rotation of the first valve body can adjust the opening size of the first valve body. The larger the opening of the first valve body, the greater the flow rate through the first pipeline.

[0008] In the first coupling state, during the rotation of the first valve body, the opening of the first valve body is in a constantly changing state, and the opening size of the first valve body is related to the time when the first valve body assembly is in the first coupling state.

[0009] In the first decoupling state, the first drive disk module rotates but the first valve body does not rotate, the opening of the first valve body does not change, and the opening of the first valve body is the opening before the first decoupling state and in the first coupling state. When the flow in the first pipeline needs to be adjusted, the first valve body assembly is controlled to change from the first decoupling state to the first coupling state, the first valve body rotates to a preset opening, and the first valve body assembly is controlled to change from the first coupling state to the first decoupling state, at which time the flow in the first pipeline is adjusted to a preset flow at a preset opening.

[0010] The second valve body assembly can switch between a second coupling state and a second decoupling state. In the second coupling state, the rotation of the second drive disk module can drive the second valve body to rotate. The second valve body is located in the second pipeline. The rotation of the second valve body can adjust the opening size of the second valve body. The larger the opening of the second valve body, the greater the flow rate through the second pipeline.

[0011] In the second coupling state, the opening of the second valve body is in a constantly changing state during the rotation of the second valve body, and the opening of the second valve body is related to the time when the second valve body assembly is in the second coupling state.

[0012] In the second decoupling state, the second drive disk module rotates but the second valve body does not rotate, the opening of the second valve body does not change, and the opening of the second valve body is the opening before the second decoupling state and in the second coupling state. When the flow in the second pipeline needs to be adjusted, the second valve body assembly is controlled to change from the second decoupling state to the second coupling state, the second valve body rotates to a preset opening, and the second valve body assembly is controlled to change from the second coupling state to the second decoupling state, at which time the flow in the second pipeline is adjusted to a preset flow at a preset opening.

[0013] In one embodiment, when the first valve body assembly is in a first coupling state, the opening change rate of the first valve body is equal to the opening change rate of the second valve body assembly is in a second coupling state, so that the flow changes in the first pipeline and the second pipeline are the same.

[0014] In one embodiment, the opening change rate of the first valve body when the first valve body assembly is in the first coupling state is not equal to the opening change rate of the second valve body when the second valve body assembly is in the second coupling state, so that the flow changes in the first pipeline and the second pipeline are different, which can be applied to different scene requirements.

[0015] By setting the first drive disk module and the second drive disk module, the coupling shaft does not directly control the opening of the first valve body and the second valve body, but indirectly controls the opening of the first valve body and the second valve body through the first drive disk module and the second drive disk module respectively. When the coupling shaft rotates, it can drive the first drive disk module and the second drive disk module to rotate at the same time, and can simultaneously control or separately control the coupling and decoupling of the first drive disk module and the first valve body, and the coupling and decoupling of the second drive disk module and the second valve body, so as to achieve synchronous or asynchronous adjustment of the opening of the first valve body and the second valve body, so that the flow through the first valve body and the second valve body can be adjusted and flexibly controlled as needed to meet the requirements of the flow size in the first pipeline and the second pipeline in different scenarios, save energy consumption, and the flow control device is more widely used. On the other hand, one coupling shaft can realize the control of the opening of the first valve body and the second valve body, which can reduce the volume of the flow control device, reduce energy consumption, and save costs.

[0016] In a possible implementation, when the first valve body assembly is in the first coupling state, the second valve body assembly is in the second coupling state. The first drive disk module is controlled to couple with the first valve body and the second drive disk module is controlled to couple with the second valve body to synchronously adjust the opening of the first valve body and the second valve body, thereby adjusting the flow of the first pipeline and the second pipeline.

[0017] In a possible implementation, when the first valve body assembly is in the first decoupling state, the second valve body assembly is in the second decoupling state. At the same time, the first drive disk module is controlled to be decoupled from the first valve body and the second drive disk module is controlled to be decoupled from the second valve body, so as to synchronously adjust the opening of the first valve body and the second valve body, thereby adjusting the flow of the first pipeline and the second pipeline.

[0018] In a possible implementation, when the first valve body assembly is in a first decoupled state, the second valve body assembly is in a second coupled state. When the first valve body assembly is in the first decoupled state, the first drive disk module is controlled to be decoupled from the first valve body, and the second valve body assembly is in the second coupled state, and the second drive disk module is controlled to be coupled to the second valve body, so as to adjust the different openings of the first valve body and the second valve body, thereby achieving asynchronous adjustment of the flow rates of the first pipeline and the second pipeline.

[0019] In a possible implementation, when the first valve body assembly is in a first coupling state, the second valve body assembly is in a second coupling and decoupling state. When the first valve body assembly is in the first coupling state, the first drive disk module is controlled to couple with the first valve body, and the second valve body assembly is in a second decoupling state, and the second drive disk module is controlled to decouple with the second valve body, so as to adjust the different openings of the first valve body and the second valve body, thereby achieving asynchronous adjustment of the flow rates of the first pipeline and the second pipeline.

[0020] In one embodiment, the first valve body may also be a valve with adjustable opening, such as a ball valve, a disc valve, or a butterfly valve.

[0021] In one embodiment, the second valve body may also be a valve with adjustable opening, such as a disc valve or a butterfly valve.

[0022] In a possible implementation, the first valve body assembly further includes a first transmission component, and the first drive disk module and the first valve body are coupled or decoupled through the first transmission component.

At this time, the first elastic member is compressed to a greater extent than when the first excitation coil is not energized; when the first excitation coil is de-energized, the magnetic force generated by the first excitation coil disappears. At this time, since the first elastic member is compressed, the elastic force of the first elastic member enables the first moving disk to move along the axial direction of the connecting shaft away from the first excitation coil.

[0026] In one embodiment, the first elastic member may be a spring, a spring sheet or an elastic body, etc. In one embodiment, the first elastic member is a spring, which is sleeved on the outer peripheral side of the connecting shaft. In other embodiments, the first driving disk module may also include a plurality of springs, which are located on the outer peripheral side of the connecting shaft, and both ends of the plurality of springs are respectively connected to the first moving disk and the first excitation coil.

[0027] In a possible implementation, the second valve body assembly further includes a second transmission component, and the second drive disk module and the second valve body are coupled or decoupled via the second transmission component. In a second coupled state, the second drive disk module drives the second transmission component to rotate, thereby driving the second valve body to rotate. In a second decoupled state, the second drive disk module is decoupled from the second transmission component, the second transmission component and the second valve body do not rotate, and the flow in the second pipeline does not change.

In one embodiment, the third transmission disc is provided with stoppers at both ends of the axial direction of the coupling shaft, so that the third transmission disc cannot move in the axial direction of the coupling shaft. In one embodiment, the third transmission disc is annular and the third transmission disc is sleeved on the outer peripheral side of the coupling shaft.

[0029] In one possible implementation, the second drive disk module includes a second moving disk, a second excitation coil and a second elastic member, the second excitation coil is fixed to the connecting shaft, the second moving disk is sleeved on the connecting shaft, the second elastic member is connected between the second moving disk and the second excitation coil, when the second excitation coil is energized, the second moving disk is arranged close to the second excitation coil, when the second excitation coil is de-energized, the second moving disk is arranged away from the second excitation coil, and the second moving disk and the third transmission disk are coupled or decoupled by the second excitation coil and the second elastic member.

[0030] Among them, the second excitation coil can rotate with the connecting shaft, the second excitation coil and the connecting shaft are relatively fixed in the circumferential direction of the connecting shaft, and the second excitation coil and the connecting shaft are relatively fixed in the axial direction of the connecting shaft, that is, the second excitation coil is stationary relative to the connecting shaft, and the second excitation coil cannot move relative to the connecting shaft in the axial direction and the circumferential direction; the second movable disk can rotate with the connecting shaft, the second movable disk and the connecting shaft are relatively fixed in the circumferential direction of the connecting shaft, but the second movable disk and the connecting shaft are not fixed in the axial direction of the connecting shaft, the second movable disk can move along the axial direction of the connecting shaft, the second movable disk and the second excitation coil are connected by the second elastic member, and the second elastic member can elastically expand and contract along the axial direction of the connecting shaft. When the second excitation coil is energized, the second excitation coil generates a magnetic force, so that the second moving disk can move along the axial direction of the connecting shaft toward the second excitation coil. At this time, the second elastic member is compressed to a greater extent than when the second excitation coil is not energized; when the second excitation coil is de-energized, the magnetic force generated by the second excitation coil disappears. At this time, since the second elastic member is compressed, the elastic force of the second elastic member enables the second moving disk to move along the axial direction of the connecting shaft away from the second excitation coil.

[0031] In one embodiment, the second elastic member may be a spring, a spring sheet or an elastic body, etc. In one embodiment, the second elastic member is a spring, which is sleeved on the outer peripheral side of the connecting shaft. In other embodiments, the second driving disk module may also include a plurality of springs, which are located on the outer peripheral side of the connecting shaft, and both ends of the plurality of springs are respectively connected to the second moving disk and the second excitation coil.

[0033] Wherein, the first excitation coil is located at a side of the first movable disk away from the first transmission disk. When the first excitation coil is energized, the first excitation coil generates a magnetic force, so that the first movable disk moves along the axial direction of the connecting shaft close to the first excitation coil and moves away from the first transmission disk. The first transmission disk is spaced apart from the first movable disk. The rotational force on the first transmission disk cannot be transmitted to the first transmission disk, the first transmission disk does not rotate, and the first drive disk module is in a first decoupled state. When the first excitation coil is powered off, the magnetic force generated by the first excitation coil disappears. During the process of restoring the first elastic member in a compressed state, the elastic force of the first elastic member causes the first movable disk to move along the axial direction of the connecting shaft close to the first transmission disk until it abuts against the first transmission disk. The elastic force of the first elastic member can press the first movable disk and the first transmission disk tightly, so that the rotational force on the first transmission disk is transmitted to the first transmission disk.

When the second excitation coil is energized, the second excitation coil generates a magnetic force, so that the second movable disk moves along the axial direction of the connecting shaft close to the second excitation coil and moves away from the third transmission disk. The third transmission disk is spaced apart from the second movable disk, and the rotational force on the third transmission disk cannot be transmitted to the third transmission disk, the third transmission disk does not rotate, and the second drive disk module is in a second decoupled state; when the second excitation coil is powered off, the magnetic force generated by the second excitation coil disappears, and during the process of the second elastic member in the compressed state restoring to its original state, the elastic force of the second elastic member causes the second movable disk to move along the axial direction of the connecting shaft close to the third transmission disk until it abuts against the third transmission disk. The elastic force of the second elastic member can press the second movable disk and the third transmission disk tightly, so that the rotational force on the third transmission disk is transmitted to the third transmission disk, and the third transmission disk rotates to adjust the opening of the second valve body. At this time, the second drive disk module is in a second coupled state. By controlling the power-off time of the second excitation coil, the coupling time of the second moving plate and the third transmission plate can be controlled to adjust the opening of the second valve body and realize the control of the flow rate in the second pipeline.

[0036] In a possible implementation, the first excitation coil and the first moving disk are respectively located on both sides of the first transmission disk along the axial direction of the connecting shaft. When the first excitation coil is energized, the first drive disk module is in the first coupling state; when the first excitation coil is de-energized, the first drive disk module is in the first decoupling state.

[0037] When the first excitation coil is powered on, the first excitation coil generates a magnetic force, so that the first movable disk moves along the axial direction of the coupling shaft close to the first excitation coil and moves close to the first transmission disk until it abuts against the first transmission disk. The magnetic force of the first excitation coil can press the first movable disk and the first transmission disk tightly, so that the rotational force on the first transmission disk is transmitted to the first transmission disk, and the first transmission disk rotates to adjust the opening of the first valve body. At this time, the first elastic member is in a compressed state, and the first drive disk module is in a first coupling state. By controlling the power-on time of the first excitation coil, the coupling time of the first movable disk and the first transmission disk can be controlled to adjust the opening of the first valve body and realize the control of the flow size in the first pipeline. When the first excitation coil is powered off, the magnetic force generated by the first excitation coil disappears, and the elastic force of the first elastic member causes the first movable disk to move along the axial direction of the coupling shaft away from the first transmission disk and the first excitation coil.

[0039] When the second excitation coil is energized, the second excitation coil generates a magnetic force, so that the second movable disk moves along the axial direction of the connecting shaft close to the second excitation coil and close to the third transmission disk until it abuts against the third transmission disk. The magnetic force of the second excitation coil can press the second movable disk and the third transmission disk tightly, so that the rotational force on the third transmission disk is transmitted to the third transmission disk, and the third transmission disk rotates to adjust the opening of the second valve body. At this time, the second elastic member is in a compressed state, and the second drive disk module is in a second coupling state. By controlling the energization time of the second excitation coil, the coupling time of the second movable disk and the third transmission disk can be controlled to adjust the opening of the second valve body, thereby realizing the control of the flow rate in the second pipeline.

The third transmission disk is spaced apart from the second moving disk, and the rotational force on the third transmission disk cannot be transmitted to the third transmission disk, so the third transmission disk does not rotate, and the second drive disk module is in a second decoupling state.

[0040] In a possible implementation, the flow regulating device further includes a first controller, which is electrically connected to the first excitation coil and is used to control power on and power off of the first excitation coil.

[0041] In a possible implementation, the flow regulating device further includes a second controller, and the second controller is electrically connected to the second excitation coil and is used to control power on and power off of the second excitation coil.

[0042] In a possible implementation, a first groove is provided on the surface of the first transmission disc facing the first moving disc. When the first transmission disc is coupled with the first moving disc, the first moving disc is located in the first groove, and the first moving disc and the first transmission disc are relatively fixed in the circumferential direction of the coupling shaft. Wherein, the size of the first moving disc is smaller than the size of the first transmission disc. When the first drive disc module is in the first coupling state, the first moving disc can drive the first transmission disc to rotate through the friction between the first groove and the first moving disc. In one embodiment, the rotation speed of the first transmission disc is smaller than the rotation speed of the first moving disc. At this time, the first transmission disc and the first moving disc move relative to each other in the circumferential direction, which not only causes greater wear on the first transmission disc and the first moving disc, but also causes energy loss. Therefore, the friction between the first groove and the first moving disc can be strengthened, so that the rotation speeds of the first transmission disc and the first moving disc are equal or approximately equal, that is, the first moving disc and the first transmission disc are relatively fixed in the circumferential direction of the coupling shaft. On the one hand, the wear of the first transmission disc and the first moving disc is reduced, and energy consumption is saved; on the other hand, the volume of the flow regulating device is reduced, so that the flow regulating device can adapt to small-sized application scenarios.

[0043] In a possible implementation, a first limiting portion is provided on the side wall of the first groove, and a second limiting portion is provided on the outer circumference of the first movable plate. When the first transmission plate is coupled with the first movable plate, the first limiting portion and the second limiting portion cooperate to relatively fix the first movable plate and the first transmission plate in the circumferential direction of the coupling shaft. The first limiting portion and the second limiting portion are used to enhance the friction between the first transmission plate and the first movable plate, so that the first movable plate can better drive the first transmission plate to rotate.

[0044] In one embodiment, both the first limiting portion and the second limiting portion are gears, and the transmission between the first movable plate and the first transmission plate is achieved through the meshing of the first limiting portion and the second limiting portion. In one embodiment, the first limiting portion is a boss, and the second limiting portion is a recessed hole. When the first transmission plate is coupled with the first movable plate, the first limiting portion is located in the second limiting portion. In other embodiments, the first limiting portion and the second limiting portion are not limited to the above forms. In one embodiment, the size of the first movable plate is larger than the size of the first transmission plate, and a groove is provided on the surface of the first movable plate facing the first transmission plate. When the first transmission plate is coupled with the first movable plate, the first transmission plate is located in the groove of the first transmission plate.

[0045] In one embodiment, the first limiting portion may also be arranged on the groove bottom of the first groove, and the second limiting portion may also be arranged on the side of the first moving plate close to the first transmission plate.

[0046] In a possible implementation, a second groove is provided on the surface of the third transmission disc facing the second movable disc, and when the third transmission disc is coupled with the second movable disc, the second movable disc is located in the second groove, and the second movable disc and the third transmission disc are relatively fixed in the circumferential direction of the coupling shaft. The size of the second movable disc is smaller than that of the third transmission disc, and when the second drive disc module is in the second coupling state, the friction between the second groove and the second movable disc enables the second movable disc to drive the third transmission disc to rotate. In one embodiment, the rotation speed of the third transmission plate is less than the rotation speed of the second moving plate. At this time, the third transmission plate and the second moving plate move relative to each other in the circumferential direction, which will not only cause greater wear to the third transmission plate and the second moving plate, but also cause energy loss. Therefore, the friction between the second groove and the second moving plate can be strengthened to make the rotation speeds of the third transmission plate and the second moving plate equal or approximately equal, that is, the second moving plate and the third transmission plate are relatively fixed in the circumferential direction of the connecting shaft. On the one hand, the wear of the third transmission plate and the second moving plate is reduced, saving energy; on the other hand, the volume of the flow regulating device is reduced, so that the flow regulating device can adapt to small-sized application scenarios.

[0047] In a possible implementation, a third limiting portion is provided on the side wall of the second groove, and a fourth limiting portion is provided on the outer circumference of the second movable plate. When the third transmission plate is coupled with the second movable plate, the third limiting portion and the fourth limiting portion cooperate to relatively fix the second movable plate and the third transmission plate in the circumferential direction of the coupling shaft. The third limiting portion and the fourth limiting portion are used to enhance the friction between the third transmission plate and the second movable plate, so that the second movable plate can better drive the third transmission plate to rotate.

[0048] In one embodiment, the third limiting part and the fourth limiting part are both gears, and the transmission between the second movable plate and the third transmission plate is achieved through the meshing of the third limiting part and the fourth limiting part. In one embodiment, the third limiting part is a boss, and the fourth limiting part is a recessed hole. When the third transmission plate is coupled with the second movable plate, the third limiting part is located in the fourth limiting part. In other embodiments, the third limiting part and the fourth limiting part are not limited to the above forms. In one embodiment, the size of the second movable plate is larger than the size of the third transmission plate, and a groove is provided on the surface of the second movable plate facing the third transmission plate. When the third transmission plate is coupled with the second movable plate, the third transmission plate is located in the groove of the third transmission plate.

[0049] In one embodiment, the third limiting portion may also be arranged on the groove bottom of the second groove, and the fourth limiting portion may also be arranged on the side surface of the second moving plate close to the third transmission plate.

[0050] In a possible implementation, the flow regulating device further includes a first motor, which is located at one end of the coupling shaft and is used to drive the coupling shaft to rotate. The first motor drives the coupling shaft to rotate and simultaneously provides power to the first valve body assembly and the second valve body assembly to regulate the flow in the first pipeline and the second pipeline, thereby achieving high-efficiency operation of the flow regulating device and reducing the volume of the flow regulating device.

[0051] In a possible implementation, the flow regulating device further includes a second motor, which is located at one end of the connecting shaft away from the first motor. By setting two motors at the same time, on the one hand, sufficient power can be provided to drive the connecting shaft to rotate, especially when the flow regulating device includes more than two valve body assemblies, the two motors can provide greater power to drive the connecting shaft to rotate; on the other hand, the two motors working at the same time make the flow regulating device more reliable, when one of the motors is damaged, the other motor can still work, and the flow regulating device can still play the role of regulating the flow; on the other hand, only two motors are needed to regulate the flow of two or more pipelines, so as to realize the high-efficiency operation of the flow regulating device.

[0052] In a second aspect, the present application provides a cooling system, which includes a first pipe, a second pipe and a flow regulating device as described in any one of the above items, wherein the first valve body is connected to the first pipe, and the second valve body is connected to the second pipe, and the flow of the first pipe and the second pipe are respectively adjusted by rotating the first valve body and the second valve body.

[0053] In one embodiment, the connection method between the valve body and the pipeline includes, but is not limited to, flange connection, clamp connection, butt welding connection, threaded connection, ferrule connection, clamp connection and the like.

[0054] In one embodiment, the cooling system further comprises a first cold plate and a second cold plate, the first cold plate and the second cold plate are respectively connected to the first pipe and the second pipe, and the first cold plate and the second cold plate are used to increase the cooling area. In one embodiment, the first cold plate and the second cold plate are provided with cooling liquid, and the flow rate of the first pipe and the second pipe is adjusted by the flow regulating device to adjust the cooling efficiency of the first cold plate and the second cold plate.

[0055] It should be noted that the use scenario of the flow regulating device of the present application is not limited to cooling systems, and can be applied to other liquid systems that require multi-valve regulation.

[0056] In a third aspect, the present application provides a cabinet, the cabinet comprising a first heat source, a second heat source and a cooling system as described above, the first pipe is used to cool the first heat source, and the second pipe is used to cool the second heat source. The first heat source and the second heat source can be a server, a power module or a switch, etc., or a data processor, a central processing unit or other devices, which is not limited in the present application. The cooling system is fixed to the frame of the cabinet, and a coolant is provided in the first pipe and the second pipe. When the coolant flows in the first pipe and the second pipe, the heat generated by the first heat source and the second heat source is taken away, thereby achieving heat dissipation of the first heat source and the second heat source.

[0057] In one embodiment, the cooling system further includes a first cold plate and a second cold plate, and the first cold plate and the second cold plate are respectively arranged in contact with the first heat source and the second heat source. The cooling system can adjust the flow rate of the coolant flowing through the first cold plate and the second cold plate according to the heating conditions of the first heat source and the second heat source, so as to better cool the first heat source and the second heat source and save energy. For example, when the heat generation of the first heat source increases, the flow rate of the first pipeline is adjusted to increase to improve the cooling effect of the first cold plate on the first heat source; when the heat generation of the second heat source decreases, the flow rate of the second pipeline is adjusted to decrease to reduce energy consumption. The first cold plate can be located on the upper surface, lower surface or peripheral side of the first heat source, and the second cold plate can be located on the upper surface, lower surface or peripheral side of the second heat source, which can be set according to needs.

[0058] In one embodiment, the cooling system further includes a pump and a cooler, wherein the pump is used to drive the coolant to flow in the first pipe, the second pipe, the first cold plate, and the second cold plate. During the circulation of the coolant, the cooler converts the inflowing coolant with a higher temperature into a coolant with a lower temperature, and the coolant with a lower temperature flows into the first cold plate and the second cold plate to cool the first heat source and the second heat source, and the coolant with a higher temperature in the first cold plate and the second cold plate flows out to the cooler for cooling to continue to participate in the circulation.

[0059] In the present application, by setting the first drive disk module and the second drive disk module, the connecting shaft indirectly controls the opening of the first valve body and the second valve body through the first drive disk module and the second drive disk module respectively, and the connecting shaft can drive the first drive disk module and the second drive disk module to rotate at the same time when rotating, and can simultaneously control or separately control the coupling and decoupling of the first drive disk module and the first valve body, and the coupling and decoupling of the second drive disk module and the second valve body, so as to achieve synchronous or asynchronous adjustment of the opening of the first valve body and the second valve body, so that the flow through the first valve body and the second valve body can be adjusted and flexibly controlled as needed to meet the requirements of the flow size in the first pipeline and the second pipeline in different scenarios, save energy consumption, and the flow regulating device is more widely used. On the other hand, one connecting shaft can realize the control of the opening of the first valve body and the second valve body, which can reduce the volume of the flow regulating device, reduce energy consumption, and save costs.

[0078] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0079] In this document, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0080] Coupling: Coupling refers to two or more systems that influence each other and even combine through interaction. For example, component 1 is coupled with component 2, and when component 1 rotates, component 2 can be driven to rotate. Component 1 and component 2 can be coupled directly or indirectly through other components.

[0081] Decoupling: Decoupling refers to the separation of two or more systems and their independence from each other. For example, component 1 and component 2 are decoupled, and when component 1 rotates, component 2 cannot be driven to rotate.

[0082] See also Figure 1 , Figure 1 1 is a schematic diagram of a flow regulating device provided by an embodiment of the present application. An embodiment of the present application provides a flow regulating device 10, which includes a connecting shaft 300, a first valve body assembly 100 and a second valve body assembly 200; the connecting shaft 300 can rotate; the first valve body assembly 100 has a first coupling state and a first decoupling state, the first valve body assembly 100 includes a first drive disk module 110 and a first valve body 120, the first drive disk module 110 and the connecting shaft 300 are relatively fixed in the circumferential direction C of the connecting shaft 300, and in the first coupling state (such as Figure 6 As shown), the first drive disk module 110 is coupled to the first valve body 120 so that the shaft 300 drives the first valve body 120 to rotate. In the first decoupling state (as shown Figure 5 As shown in FIG. 1 ), the first drive disk module 110 is decoupled from the first valve body 120; the second valve body assembly 200 has a second coupled state and a second decoupled state, the second valve body assembly 200 includes a second drive disk module 210 and a second valve body 220, the second drive disk module 210 and the connecting shaft 300 are relatively fixed in the circumferential direction C of the connecting shaft 300, and in the second coupled state (as shown in FIG. Figure 6 As shown), the second drive disk module 210 is coupled to the second valve body 220 so that the shaft 300 drives the second valve body 220 to rotate. In the second decoupling state (as shown Figure 5 As shown in FIG. 2 , the second driving disk module 210 is decoupled from the second valve body 220 .

[0083] The flow regulating device 10 is used to regulate the flow of the fluid in the first pipe 21 and the second pipe 22 (eg Figure 1When the first pipe 21 is connected to the first valve body 120, the first valve body 120 rotates to adjust the flow rate in the first pipe 21 and can control the opening and closing of the first pipe 21. When the second pipe 22 is connected to the second valve body 220, the second valve body 220 rotates to adjust the flow rate in the second pipe 22 and can control the opening and closing of the second pipe 22.

[0084] The first drive disk module 110 and the second drive disk module 210 are both fixed on the connecting shaft 300. When the connecting shaft 300 rotates, it can drive the first drive disk module 110 and the second drive disk module 210 to rotate. In this embodiment, the rotation speed of the first drive disk module 110 and the second drive disk module 210 is equal to or approximately equal to the rotation speed of the connecting shaft 300. In one embodiment, the connecting shaft 300 is fixed to the output shaft of the first motor 510, and the first motor 510 drives the connecting shaft 300 to rotate. In one embodiment, the first drive disk module 110 and the second drive disk module 210 are arranged at intervals. In other embodiments, the first drive disk module 110 and the second drive disk module 210 can also be arranged in contact. In one embodiment, the first drive disk module 110 and the second drive disk module 210 are annular and sleeved on the outer peripheral side of the connecting shaft 300. In one embodiment, the first drive disk module 110 and the second drive disk module 210 can also be block-shaped.

[0085] The first valve body assembly 100 can be switched between a first coupled state and a first decoupled state. Figure 6 As shown in the figure, the rotation of the first drive disk module 110 can drive the first valve body 120 to rotate. The first valve body 120 is located in the first pipe 21. The rotation of the first valve body 120 can adjust the opening size of the first valve body 120. The larger the opening size of the first valve body 120 is, the greater the flow rate through the first pipe 21 is.

[0086] In the first coupling state, the opening of the first valve body 120 is in a constantly changing state during the rotation of the first valve body 120, and the opening of the first valve body 120 is related to the time when the first valve body assembly 100 is in the first coupling state. For example, if the first valve body assembly 100 is in a closed state before the first coupling state, the opening of the first valve body 120 is the smallest, that is, the opening is zero, and the first pipeline 21 is not flowing. At this time, when the first valve body assembly 100 is transformed into the first coupling state, the opening of the first valve body 120 first gradually increases to the maximum opening, and then gradually decreases to zero, and this cycle can continue.

[0087] In the first decoupling state (such as Figure 5As shown in FIG. 1 , the first drive disk module 110 rotates but the first valve body 120 does not rotate, and the opening of the first valve body 120 does not change. The opening of the first valve body 120 is the opening before the first decoupling state and in the first coupling state. When the flow in the first pipeline 21 needs to be adjusted, the first valve body assembly 100 is controlled to change from the first decoupling state to the first coupling state, the first valve body 120 rotates to a preset opening, and the first valve body assembly 100 is controlled to change from the first coupling state to the first decoupling state. At this time, the flow in the first pipeline 21 is adjusted to the preset flow at the preset opening.

[0088] The second valve body assembly 200 can switch between a second coupled state and a second decoupled state. Figure 6 As shown in the figure, the rotation of the second drive disk module 210 can drive the second valve body 220 to rotate. The second valve body 220 is located in the second pipe 22. The rotation of the second valve body 220 can adjust the opening size of the second valve body 220. The larger the opening size of the second valve body 220 is, the greater the flow rate through the second pipe 22 is.

[0089] In the second coupling state, the opening of the second valve body 220 is in a constantly changing state during the rotation of the second valve body 220, and the opening of the second valve body 220 is related to the time when the second valve body assembly 200 is in the second coupling state. For example, if the second valve body assembly 200 is in a closed state before the second coupling state, the opening of the second valve body 220 is the smallest, that is, the opening is zero, and the second pipeline 22 is not flowing. At this time, when the second valve body assembly 200 is transformed into the second coupling state, the opening of the second valve body 220 first gradually increases to the maximum opening, and then gradually decreases to zero, and this cycle can continue.

[0090] In the second decoupling state (such as Figure 5 As shown in FIG. 2 , the second drive disk module 210 rotates but the second valve body 220 does not rotate, and the opening of the second valve body 220 does not change. The opening of the second valve body 220 is the opening before the second decoupling state and when it is in the second coupling state. When the flow in the second pipeline 22 needs to be adjusted, the second valve body assembly 200 is controlled to change from the second decoupling state to the second coupling state, and the second valve body 220 rotates to a preset opening. The second valve body assembly 200 is controlled to change from the second coupling state to the second decoupling state. At this time, the flow in the second pipeline 22 is adjusted to the preset flow at the preset opening.

[0091] In one embodiment, the opening change rate of the first valve body 120 when the first valve body assembly 100 is in the first coupling state is equal to the opening change rate of the second valve body 220 when the second valve body assembly 200 is in the second coupling state, so that the flow changes in the first pipeline 21 and the second pipeline 22 are the same.

[0092] In one embodiment, the opening change rate of the first valve body 120 when the first valve body assembly 100 is in the first coupling state is not equal to the opening change rate of the second valve body 220 when the second valve body assembly 200 is in the second coupling state, so that the flow changes in the first pipeline 21 and the second pipeline 22 are different, which can be applied to different scenarios.

[0093] In a possible implementation, when the first valve body assembly 100 is in the first coupling state, the second valve body assembly 200 is in the second coupling state. At the same time, the first drive disk module 110 is controlled to couple with the first valve body 120 and the second drive disk module 210 is controlled to couple with the second valve body 220 to synchronously adjust the opening of the first valve body 120 and the second valve body 220, thereby adjusting the flow of the first pipeline 21 and the second pipeline 22.

[0094] In a possible implementation, when the first valve body assembly 100 is in the first decoupling state, the second valve body assembly 200 is in the second decoupling state. At this time, the opening of the first valve body 120 and the opening of the second valve body 220 can be the same or different, and the first drive disk module 110 is controlled to be decoupled from the first valve body 120 and the second drive disk module 210 is controlled to be decoupled from the second valve body 220, so as to synchronously adjust the opening of the first valve body 120 and the second valve body 220, thereby adjusting the flow of the first pipeline 21 and the second pipeline 22.

[0095] In a possible implementation, when the first valve body assembly 100 is in the first decoupling state, the second valve body assembly 200 is in the second coupling state. When the first valve body assembly 100 is in the first decoupling state, the first drive disk module 110 is controlled to be decoupled from the first valve body 120, and the second valve body assembly 200 is in the second coupling state, and the second drive disk module 210 is controlled to be coupled with the second valve body 220, so as to adjust the different openings of the first valve body 120 and the second valve body 220, thereby realizing asynchronous adjustment of the flow of the first pipeline 21 and the second pipeline 22. Exemplarily, the opening of the first valve body 120 is greater than the opening of the second valve body 220, so that the flow of the first pipeline 21 is greater than the flow of the second pipeline 22. Exemplarily, the opening of the first valve body 120 is less than the opening of the second valve body 220, so that the flow of the first pipeline 21 is less than the flow of the second pipeline 22.

[0096] In a possible implementation, when the first valve body assembly 100 is in the first coupling state, the second valve body assembly 200 is in the second coupling and decoupling state. When the first valve body assembly 100 is in the first coupling state, the first drive disk module 110 is controlled to couple with the first valve body 120, and the second valve body assembly 200 is in the second decoupling state, and the second drive disk module 210 is controlled to decouple with the second valve body 220, so as to adjust the different openings of the first valve body 120 and the second valve body 220, thereby realizing asynchronous adjustment of the flow of the first pipeline 21 and the second pipeline 22. Exemplarily, the opening of the first valve body 120 is greater than the opening of the second valve body 220, so that the flow of the first pipeline 21 is greater than the flow of the second pipeline 22. Exemplarily, the opening of the first valve body 120 is less than the opening of the second valve body 220, so that the flow of the first pipeline 21 is less than the flow of the second pipeline 22.

[0097] If the first drive disk module 110 and the second drive disk module 210 are not provided, the first valve body 120 and the second valve body 220 are directly connected to the connecting shaft 300, and the connecting shaft 300 rotates and drives the first valve body 120 and the second valve body 220 to rotate at the same time. When the connecting shaft 300 stops rotating, the first valve body 120 and the second valve body 220 also stop rotating immediately. This implementation can only achieve synchronous adjustment of the opening of the first valve body 120 and the second valve body 220, and cannot achieve asynchronous adjustment of the opening of the first valve body 120 and the second valve body 220. For example, this implementation cannot achieve the adjustment of the opening of only one valve body while the opening of the other valve body remains unchanged. At this time, if different pipelines have different flow requirements, energy consumption loss of one pipeline will be caused at the same flow rate. If asynchronous regulation is required, two connecting shafts 300 need to be set up. The two connecting shafts 300 are respectively connected to the first valve body 120 and the second valve body 220, and the two connecting shafts 300 respectively control the opening of the first valve body 120 and the second valve body 220. At this time, the number of connecting shafts 300 is increased, the volume of the flow regulating device 10 is increased, and the cost is increased.

[0098] In the present embodiment, by providing the first drive disk module 110 and the second drive disk module 210, the connecting shaft 300 does not directly control the opening of the first valve body 120 and the second valve body 220, but indirectly controls the opening of the first valve body 120 and the second valve body 220 respectively through the first drive disk module 110 and the second drive disk module 210. When the connecting shaft 300 rotates, it can drive the first drive disk module 110 and the second drive disk module 210 to rotate at the same time, and can simultaneously control or separately control the coupling and decoupling of the first drive disk module 110 and the first valve body 120, and the coupling and decoupling of the second drive disk module 210 and the second valve body 220, so as to achieve synchronous or asynchronous adjustment of the opening of the first valve body 120 and the second valve body 220, so that the flow through the first valve body 120 and the second valve body 220 can be adjusted and flexibly controlled as needed to meet the requirements of the flow size in the first pipeline 21 and the second pipeline 22 in different scenarios, save energy consumption, and the flow regulating device 10 is more widely used. On the other hand, one connecting shaft 300 can realize the control of the opening of the first valve body 120 and the second valve body 220, which can reduce the volume of the flow regulating device 10, reduce energy consumption and save costs.

[0099] In one embodiment, the first valve body 120 is a ball valve (such as Figure 2 As shown in FIG. 1 , the first valve body 120 includes a shell 121, a sphere 122 and a connecting rod 123. The shell 121 is provided with a first hole 1211, and both ends of the first hole 1211 are connected to the first pipe 21. The sphere 122 is provided with a second hole 1221 that penetrates the sphere 122. The sphere 122 is located in the shell 121 and the sphere 122 and the connecting rod 123 are fixedly connected. The connecting rod 123 is used to couple or decouple with the first drive disk module 110. In the first coupling state, when the connecting rod 123 is coupled with the first drive disk module 110, the rotation of the first drive disk module 110 can drive the connecting rod 123 on the first valve body 120 to rotate, thereby driving the sphere 122 to rotate, and the sphere 122 rotates to adjust the opening size of the first valve body 120.

[0100] For example, when the extension direction of the first channel 1211 is perpendicular to the extension direction of the second channel 1221 (eg Figure 2 As shown), the opening of the first valve body 120 is zero, and the first valve body 120 is in a fully closed state. At this time, the fluid in the first pipeline 21 stops flowing.

[0101] For example, when the connecting rod 123 drives the ball 122 to rotate, the extension direction of the first hole 1211 intersects with the extension direction of the second hole 1221 (eg, Figure 3 As shown), the first valve body 120 is in an open state. At this time, the fluid flows into the first valve body 120 from one end of the first channel, flows through the second channel 1221 and then flows out from the other end of the first channel 1211.

[0102] For example, when the extension direction of the first channel 1211 is parallel to the extension direction of the second channel 1221 (eg Figure 4 As shown), the opening of the first valve body 120 is the largest, and the first valve body 120 is in a fully open state.

[0103] In one embodiment, the first valve body 120 may also be a valve with adjustable opening, such as a ball valve, a disc valve, or a butterfly valve.

[0104] In one embodiment, the second valve body 220 may also be a disc valve, a butterfly valve, or other valves that can adjust the opening. In one embodiment, the first valve body 120 and the second valve body 220 are of the same type, for example, the first valve body 120 and the second valve body 220 are both ball valves or both butterfly valves. In one embodiment, the first valve body 120 and the second valve body 220 may also be of different types, for example, the first valve body 120 is a ball valve and the second valve body 220 is a butterfly valve, or the first valve body 120 is a butterfly valve and the second valve body 220 is a ball valve, which may be selected according to the actual requirements for the valve.

[0105] See also Figure 5 and Figure 6 In a possible implementation, the first valve body assembly 100 further includes a first transmission component 130, and the first drive disk module 110 and the first valve body 120 are coupled or decoupled via the first transmission component 130. Figure 6 As shown), the first drive disk module 110 is coupled to the first transmission component 130, and the first drive disk module 110 drives the first transmission component 130 to rotate, thereby driving the first valve body 120 to rotate to adjust the flow in the first pipeline 21; in the first decoupling state (as shown Figure 5 As shown in the figure), the first drive disk module 110 is decoupled from the first transmission component 130, the first transmission component 130 and the first valve body 120 do not rotate, and the flow in the first pipeline 21 does not change.

In the first coupling state, the first drive disc module 110 is coupled with the first transmission disc 131, the first drive disc module 110 drives the first transmission disc 131 to rotate, the first transmission disc 131 rotates and drives the second transmission disc 132 to rotate, and then drives the first valve body 120 to rotate, so as to adjust the flow in the first pipeline 21; in the first decoupling state, the first drive disc module 110 is decoupled from the first transmission disc 131, the first transmission disc 131, the second transmission disc 132 and the first valve body 120 do not rotate, and the flow in the first pipeline 21 does not change. In one embodiment, the first transmission disc 131 is provided with stoppers at both ends along the axial direction A of the connecting shaft 300 so that the first transmission disc 131 cannot move in the axial direction A of the connecting shaft 300. In one embodiment, the first transmission disc 131 is annular and is sleeved on the outer peripheral side of the connecting shaft 300.

[0107] In a possible implementation, the first drive disk module 110 includes a first moving disk 111, a first excitation coil 112, and a first elastic member 113 (eg, Figure 5 and Figure 6 As shown in the figure, the first excitation coil 112 is fixed to the connecting shaft 300, the first moving disk 111 is sleeved on the connecting shaft 300, and the first elastic member 113 is connected between the first moving disk 111 and the first excitation coil 112. When the first excitation coil 112 is energized, the first moving disk 111 is close to the first excitation coil 112. When the first excitation coil 112 is de-energized, the first moving disk 111 is away from the first excitation coil 112. The first moving disk 111 and the first transmission disk 131 are coupled or decoupled through the first excitation coil 112 and the first elastic member 113.
