[0080] The common controller cooling flow channel and internal spoiler structure is a fixed arrangement, which cannot adjust the length and structure shape of the cooling flow channel according to the heat generation of the controller and the size of the cooling flow. This will cause waste of cooling capacity and uneven and uncontrollable cooling; secondly, due to the change of flow, flow separation and wake vortex and other phenomena are easy to cause, so as to cause the cooling water channel resistance is larger, the pump body 320 power demand is multiplied, the low-temperature cooling system energy consumption increases.

[0081] Embodiment one:

[0082] As shown in Figure 2 , Figure 7 , the embodiment one of the present application provides an adjusting device 140, comprising:

[0083] The blocking structure 120 is at least partially arranged in the cooling flow channel 110, and the blocking structure 120 is at least partially movable to adjust the flow resistance of the cooling medium in the cooling flow channel 110.

[0084] The cooling flow channel 110 is used to flow the cooling medium.

[0085] By arranging the adjusting device 140 at least partially in the cooling flow channel 110, the flow resistance of the cooling medium in the cooling flow channel 110 is adjusted by the movement of the adjusting device 140, so that the cooling capacity of the cooling device 100 is controllable, the uniformity and utilization of cooling are improved, the waste of cooling capacity is avoided, and the cooling range of the cooling device 100 is increased, so that the cooling device 100 can adapt to more heat dissipation scenarios, and the heat dissipation efficiency and heat dissipation interval of the cooling system 200 are enhanced, and the reliability of the cooling system 200 is improved.

[0086] The cooling flow channel 110 for the flow-through cooling medium is provided with an adjusting device 140. The substance form of the cooling medium includes but is not limited to liquid, gas, solid-liquid mixture, and gas-liquid mixture. Here, the flow direction of the cooling medium in the cooling flow channel 110 is not limited, and can be fixed or variable. Meanwhile, the number of the flow channel inlet 151 and the flow channel outlet 152 is not specifically limited, such as Figure 1 the configuration of one flow channel inlet 151 and one flow channel outlet 152 shown in FIG. 1, or the configuration of one to two flow channel inlets to multiple flow channel outlets, which can be designed according to the requirements of the cooling flow channel and the object to be cooled.

[0087] The adjusting device 140 is at least partially arranged in the cooling flow channel 110. Specifically, the adjusting device 140 is completely arranged in the cooling flow channel 110, or 50% or 30% of the adjusting device 140 is arranged in the cooling flow channel 110.

[0088] The adjusting device 140 can be arranged as a whole movable member or a partial movable member according to requirements. For example, when the adjusting device 140 needs to be limited in a certain direction, part of the structure of the adjusting device 140 needs to be arranged as a relatively fixed component, such as Figure 4 、 Figure 5 、 Figure 6 、 Figure 2 The connecting end 123 is a relatively fixed component. When the adjusting device 140 can move as a whole in a certain direction, it can be arranged as a whole movable member, such as only controlling the movement of the adjusting device 140 along the Z direction in Figure 4 、 Figure 5 、 Figure 9 The adjusting device 140 is a whole movable member.

[0089] The adjusting device 140 is arranged in the interior of the cooling flow channel and is in contact with the inner walls of the cooling flow channel on both sides from time to time, or the adjusting device 140 can be in contact with the inner walls of the cooling flow channel. The adjusting device 140 is arranged in the interior of the cooling flow channel and is in contact with the inner walls of the cooling flow channel on both sides from time to time, which can more conveniently and efficiently adjust the flow resistance; the adjusting device 140 is arranged in the interior of the cooling flow channel and is at least partially in contact with the inner walls of the cooling flow channel, and when the adjusting device 140 is mostly in contact with the inner walls of the cooling flow channel, the cooling range of the cooling device 100 can be maximized under the premise of realizing the adjustment of the flow resistance.

[0090] Further, the blocking structure 120 extends along the first direction;

[0091] The included angle between the first direction and the second direction can be varied within a preset range to adjust the flow resistance of the cooling medium in the cooling flow channel 110;

[0092] and / or,

[0093] The blocking structure 120 can extend, retract, or move in the first direction to adjust the flow resistance of the cooling medium in the cooling channel 110.

[0094] The second direction is the direction in which the cooling medium flows.

[0095] By adjusting the length of the internal blocking structure 120 of the cooling channel, such as by extending, retracting, or moving it, flow separation and the generation of wake vortices can be reduced, thereby decreasing flow resistance. Wake vortices are detached vortices, such as those found on the back of a two-dimensional cylinder, including the well-known karman vortex street and vortices that begin to roll up at the trailing edge of an airfoil. After a certain distance from the blocking structure 120, the wake vortices gradually coalesce into a pair of vortexes with vortex nuclei. Subsequently, due to convection and viscous dissipation of vorticity, the vortex radius gradually expands, and the internal pressure and velocity gradually approach the incoming flow values. The wake vortices of the blocking structure 120 increase the resistance to the flow of the cooling medium, reducing cooling efficiency.

[0096] By adjusting the angle between the internal blocking structure 120 of the cooling channel and the flow direction or plane of the cooling medium, flow separation and the generation of wake vortices are reduced, flow resistance is decreased, making it suitable for a wider range of cooling needs, while the scope for improvement and optimization is limited. This not only enhances the efficient heat dissipation range of the cooling system 200, but also ensures the high reliability of the cooling system 200.

[0097] The barrier structure 120 is made of a material with high thermal conductivity, preferably a metal. When aluminum is chosen as the material for the barrier structure 120, the barrier structure 120 is lighter and easier to control, thus contributing to the lightweighting of the cooling device 100.

[0098] The shape of the blocking structure 120 is not specifically limited; it can be a cylinder, prism, sphere, or a combination of these shapes. Cylinders include cylindrical or elliptical cylinders, prisms include triangular, quadrangular, or polyhedral prisms, and spheres include spherical or ellipsoidal spheres. The shapes of the blocking structure 120 are all exemplified as three-dimensional shapes. This does not mean that the shapes of the blocking structure 120 do not include two-dimensional or even one-dimensional shapes, but rather that the size of an object is related to the reference object, and in the product state, it is difficult for an object to exist in an absolutely two-dimensional or absolutely one-dimensional state.

[0099] like Figure 1 As shown, the first direction is the Y direction and / or the Z direction; the second direction is the X direction, which is the direction of cooling medium flow. The angles between the X, Y, and Z directions are greater than 0° and less than 90°. The angle between the Z direction and the cooling plane is greater than 0° and less than 90°. The cooling plane is the plane containing the X and Y directions.

[0100] The adjusting device 140 can be arranged in the cooling flow channel 110 at a fixed ratio, for example, 50% of the adjusting device 140 is arranged in the cooling flow channel 110, and the adjusting device 140 can move in the cooling plane (X direction, Y direction) carrying the cooling medium. The specific movement form is that the adjusting device 140 changes the angle between the Y direction and the X direction, or the blocking structure 120 stretches or moves in the Y direction, or the adjusting device 140 changes the angle between the X direction and the Y direction, and the blocking structure 120 stretches or moves in the Y direction. If the cooling medium contains liquid, it is relatively preferred to arrange the adjusting device 140 in the cooling flow channel 110, which is more convenient for sealing. If the sealing problem can be solved, the adjusting device 140 can also be partially arranged in the cooling flow channel 110.

[0101] The adjusting device 140 can also be arranged in the cooling flow channel 110 within a certain range, for example, 50%-100% of the adjusting device 140 is arranged in the cooling flow channel 110, and the adjusting device 140 can move in the Z direction and / or the cooling plane. The specific movement form is that the adjusting device 140 changes the angle between the Z direction and / or the Y direction and the X direction, or the blocking structure 120 stretches or moves in the Z direction, or the adjusting device 140 changes the angle between the X direction and the Z direction and / or the Y direction, and the blocking structure 120 stretches or moves in the Z direction and / or the Y direction.

[0102] The angle between the blocking structure 120 and the X direction can change within a preset range. In the case where the preset X direction is a ray pointing in a certain direction, the preset range is 0°-360°; in the case where the preset X direction is a straight line extending along a certain direction, the preset range is 0°-180°. Therefore, the preset range is different according to different reference objects, and when the X direction is a ray, the preset range is zero when the preset range exceeds 360°, and the preset range is recalculated, which still belongs to the preset range claimed in the application. In specific implementation, the difference from the previous preset range can be expressed by adding a zero-one parameter, for example, the number of turns is increased by 1; or the difference can be expressed by calculating the multiple of 360.

[0103] When the blocking structure 120 stretches in a certain direction, the blocking structure 120 can be configured as any commonly used stretchable member, and the specific scheme includes but is not limited to that the blocking structure 120 is internally provided with an elastic structure, or the blocking structure 120 is configured as a stretchable pipe structure, or the blocking structure 120 is configured as a stretchable structure in the form of inflation or liquid filling.

[0104] The blocking structure 120 is generally a fixed shape structure when moving in a certain direction. At this time, the blocking structure 120 can also be a telescopic member, so that the blocking structure 120 can complete the telescopic and moving actions synchronously or distributedly, thereby further increasing the cooling range of the cooling device 100 and enhancing the heat dissipation efficiency and heat dissipation range of the cooling device 100. At the same time, the movement of the blocking structure 120 in a certain direction can be the movement of the blocking structure 120 in the Z direction, so that the volume of the blocking structure 120 in the cooling flow channel 110 changes, thereby adjusting the flow resistance; or the movement of the blocking structure 120 in the cooling plane, such as moving along the X direction and / or the Y direction, so that the blocking structure 120 moves between different flow density corresponding positions of the cooling medium, thereby adjusting the flow resistance in the cooling flow channel 110 and improving the cooling efficiency and cooling range.

[0105] Further, as shown in Figure 3 、 Figure 2 , the blocking structure 120 includes a baffle 121, and the baffle 121 is at least partially arranged in the cooling flow channel 110.

[0106] The angle between the baffle 121 and the second direction can change within a predetermined range, and / or the baffle 121 can be telescopic or movable in the first direction, and / or the baffle 121 can be telescopic or movable in the Z direction.

[0107] Embodiments of the angle change of the baffle 121 include but are not limited to: the angle change of the baffle 121 between the Z direction and the X direction, the angle change of the baffle 121 between the Y direction and the X direction, the angle change of the baffle 121 between the Z direction and the Y direction and the X direction at the same time, and the angle change of the baffle 121 between the Z direction and the Y direction and the X direction at different times.

[0108] The implementation of the angle change of the baffle 121 includes but is not limited to: when the rotation axis direction of the baffle 121 is the Z direction, the angle change of the baffle 121 between the Y direction and the X direction; when the rotation axis direction of the baffle 121 is the Y direction, the angle change of the baffle 121 between the Z direction and the X direction; when the rotation axis direction of the baffle 121 is variable, the angle change of the baffle 121 between the Z direction, the Y direction and the X direction.

[0109] The telescopic and moving embodiments of the baffle 121 include, but are not limited to: the baffle 121 telescopes in the Y direction, the baffle 121 telescopes in the Z direction, the baffle 121 telescopes in the Y direction and the Z direction simultaneously or at different times. The baffle 121 moves in the Y direction, the baffle 121 moves in the Z direction, the baffle 121 moves in the Y direction and the Z direction simultaneously or at different times. The baffle 121 telescopes and moves in the Y direction simultaneously, the baffle 121 telescopes and moves in the Y direction at different times, the baffle 121 telescopes and moves in the Z direction simultaneously, the baffle 121 telescopes and moves in the Z direction at different times, the baffle 121 telescopes and moves in the Y direction and the Z direction simultaneously, and the baffle 121 telescopes and moves in the Y direction and the Z direction at different times.

[0110] The implementation of the telescopic and moving of the baffle 121 includes, but is not limited to: when the baffle 121 is a telescopic component, the telescopic movement in the Y direction and the Z direction can be realized, thereby respectively corresponding to the regulation of the cooling medium flow resistance of the baffle 121 in the Y direction and the Z direction; when the baffle 121 is a non-variable component, the movement of the baffle 121 in the Y direction and the Z direction is controlled, thereby respectively corresponding to the regulation of the cooling medium flow resistance of the baffle 121 in the Y direction and the Z direction.

[0111] When the rotation axis direction of the baffle 121 is the Z direction, the angle between the baffle 121 in the Y direction and the X direction changes; when the rotation axis direction of the baffle 121 is the Y direction, the angle between the baffle 121 in the Z direction and the X direction changes; when the rotation axis direction of the baffle 121 is variable, the angle between the baffle 121 in the Z direction and the X direction changes, and / or the angle between the baffle 121 in the Y direction and the X direction changes.

[0112] The angle change and the telescopic and moving of the baffle 121 can be used alone or in combination.

[0113] Further, as shown in Figure 4 , Figure 5 , Figure 6 , Figure 1 The blocking structure 120 includes a baffle column 125, and the baffle column 125 is at least partially arranged in the cooling flow channel 110.

[0114] The baffle column 125 can telescope or move in the Z direction, and / or the baffle column 125 can telescope or move in the first direction.

[0115] The telescopic movement of the blocking column 125 includes, but is not limited to, the telescopic movement of the blocking column 125 in the Y direction, the telescopic movement of the blocking column 125 in the Z direction, and the telescopic movement of the blocking column 125 in the Y direction and the Z direction at the same time or at different times. The blocking column 125 moves in the Y direction, the blocking column 125 moves in the Z direction, and the blocking column 125 moves in the Y direction and the Z direction at the same time or at different times. The blocking column 125 telescopes and moves in the Y direction at the same time, the blocking column 125 telescopes and moves in the Y direction at different times, the blocking column 125 telescopes and moves in the Z direction at the same time, the blocking column 125 telescopes and moves in the Z direction at different times, the blocking column 125 telescopes and moves in the Y direction and the Z direction at the same time, and the blocking column 125 telescopes and moves in the Y direction and the Z direction at different times.

[0116] Compared with the blocking column 125, the blocking plate 121 is more suitable for adjusting the angle, and the blocking plate 121 is more suitable for a wide range of cooling requirements.

[0117] Further, as shown in Figure 1 The blocking structure 120 further includes a protruding structure 124 arranged on at least part of the surface of the blocking structure 120.

[0118] The outer surface of the protruding structure 124 is an arc surface and / or a folded surface, such as an arc surface with different radii, a folded surface with different bending angles, an outer surface formed by a plurality of folded surfaces, and a combination of these schemes. The combination scheme can be that the arc surface with different radii and the folded surface with different bending angles are spliced to form the outer surface of the protruding structure 124. Preferably, at least facing the direction of the inflow of the cooling medium, the outer surface of the protruding structure 124 is arranged as an arc surface, which is beneficial to the flow of the cooling medium, reduces the flow resistance, reduces the power loss of the pump body 320, and at the same time improves the stability of the cooling system.

[0119] The connection mode of the protruding structure 124 and the blocking plate 121 includes detachable connection or fixed connection, and the fixed connection mode includes integral connection and connection through fixed connection. The integral connection mode is a commonly used integral forming mode for those skilled in the art, including but not limited to injection molding. The fixed connection mode is a commonly used integral forming mode for those skilled in the art, including but not limited to welding, hinging, and bonding.

[0120] The materials of the protruding structure 124 and the blocking plate 121 can be the same or different. Preferably, the materials of the protruding structure 124 and the blocking plate 121 are the same, which is beneficial to heat conduction.

[0121] The protruding structures 124 on at least a portion of the surface of the baffle 121 increase the contact area between the cooling medium and the blocking structure 120, thereby enhancing the heat dissipation or cooling capacity of the cooling channel. The protruding structures 124 further ensure sufficient heat dissipation, shorten the flow path, reduce flow resistance, and also reduce the power loss of the pump body 320, while improving the stability of the cooling system. The pump body 320 provides the flow power for the cooling medium and includes, but is not limited to, a water pump. The protrusions on the surface of the blocking structure 120 increase the contact area, enhance the heat dissipation capacity of the cooling channel, ensure sufficient heat dissipation, minimize the flow path and flow resistance, reduce the power loss of the pump body 320, and improve system stability.

[0122] Furthermore, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 1 As shown, it also includes a drive member 130, which is connected to the blocking structure 120 and is used to drive the blocking structure 120 to be at least partially movable, thereby adjusting the flow resistance of the cooling medium in the cooling channel 110, expanding the cooling range, and expanding the applicable scenarios of the cooling device 100.

[0123] The connection between the drive component 130 and the blocking structure 120 makes the adjustment of the flow resistance of the cooling medium more convenient and automated, thus improving the adjustment efficiency.

[0124] The connection between the driving component 130 and the blocking structure 120 can be a one-to-one connection, with one driving component 130 connecting to one blocking structure 120; a one-to-many connection, with one driving component 130 connecting to multiple blocking structures 120; or a combination of partial one-to-one and partial one-to-many connections. The specific connection method can be set according to the design space requirements and the control scheme requirements.

[0125] Different driving components 130 can have different driving modes, thereby enabling more precise control over cooling efficiency, uniformity, and utilization rate according to cooling requirements. For example, different driving components 130 control the blocking structures 120 located at different positions. Some driving components 130 have large turning angles, while others have small turning angles. The included angle or extension length of the blocking structures 120 at corresponding positions changes, resulting in different flow resistance of the cooling medium at different positions. This allows for different cooling capacities at different positions, expanding the applicable scenarios of the cooling device.

[0126] The driving component 130 need only be able to drive the blocking structure 120 to achieve the preset activity effect; the form of the driving component 130 is not specifically limited. It can be, for example... Figure 2 , Figure 1The motor shown can also be a combination of a motor and a belt, or a combination of a motor and gears, etc.

[0127] The position of the drive component 130 is not specifically required; the drive component 130 can be as follows: Figure 2 , Figure 3 It is shown to be installed at one end of the blocking structure 120; it can also be installed outside the cooling device 100 and connected to the blocking structure 120 through a transmission structure.

[0128] Furthermore, the blocking structure 120 includes a connecting end 123, which is connected to the driving member 130.

[0129] The connecting end 123 can be located on one side or in the middle of the blocking structure 120, depending on the requirements. The middle position here includes any position not located on one side of the blocking structure 120, inside any baffle.

[0130] The connection end 123 can be located on one side or in the middle of the baffle 121, depending on the requirements. The middle position here includes any position inside the baffle that is not located on one side of the baffle 121.

[0131] When the connecting end 123 can be located on one side of the baffle 121, preferably, as follows: Figure 3 As shown, the adjusting device 140 can be located inside the cooling channel, at least partially in contact with the inner wall of the cooling channel. The connecting end 123 can be located on one side or in the middle of the baffle 121. Preferably, the adjusting device 140 can be located inside the cooling channel, and will not be in constant contact with the inner walls on both sides of the cooling channel.

[0132] The drive unit 130 and the connecting end 123 can be directly connected or indirectly connected through a transmission device, depending on the specific requirements. Direct connection is more suitable for one-to-one connections, while indirect connection is more suitable for one-to-many connections.

[0133] Furthermore, the blocking structure 120 also includes a movable end 122, which is disposed opposite to the connecting end 123.

[0134] The obstruction structure between the movable end 122 and the connecting end 123 interacts with the flow of the cooling medium, thereby affecting the flow resistance of the cooling medium. The change in the relative position of the movable end 122 and the connecting end 123 represents a change in at least one of the included angle and the extension length of the baffle 121.

[0135] like Figure 3 As shown, the angle of the blocking structure 120 changes when the movable end 122 is configured to rotate around the connecting end 123. The telescopic length of the blocking structure 120 changes when the distance between the movable end 122 and the connecting end 123 changes.

[0136] Further, the movable end 122 is arranged in an arc shape and / or arc surface, which is beneficial to reduce the resistance of the movable end 122 of the baffle 121 to the cooling medium, and facilitate the flow of the cooling medium.

[0137] Further, as shown in Figure 4 、 Figure 5 、 Figure 6 、 Figure 1 The adjusting device 140 includes a plurality of blocking structures 120. The more the number of blocking structures 120, the greater the range of regulating the flow resistance of the cooling medium.

[0138] At least two blocking structures 120 are arranged opposite to each other along the Y direction. At this time, the regulating ability of the plurality of blocking structures 120 to the flow resistance is further increased. In specific embodiments, the greater the angle between the Y direction and the X direction, the greater the regulating ability of the blocking structure 120 to the flow resistance, and the angle between the Y direction and the X direction is preferably greater than 45° and less than or equal to 90°.

[0139] Further, it includes a plurality of driving members 130, and the plurality of driving members 130 are connected one by one with the plurality of blocking structures 120.

[0140] Further, it includes one or more driving members 130, and each driving member 130 is connected with at least two blocking structures 120.

[0141] Embodiment two:

[0142] As shown in Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 7 The embodiment two of the present application provides a cooling device 100, which includes:

[0143] The cooling flow channel 110 is used for flowing the cooling medium;

[0144] According to the adjusting device 140, the flow resistance of the cooling medium in the cooling flow channel 110 is adjusted.

[0145] Further, as shown in Figure 3 It includes a first shell 114 and a cover plate 150, and the cover plate 150 and the first shell 114 surround to form the cooling flow channel 110.

[0146] The first shell 114 and the blocking structure 120 are provided with a sealing member, so as to further ensure the cooling efficiency of the cooling medium.

[0147] The shape and material of the first shell 114 are not limited. The first shell 114 can be tubular, columnar, or plate-shaped, and a flow channel for the cooling medium to pass through is required inside the first shell 114. The material of the first shell 114 is preferably selected so as not to react with the cooling medium, so as to reduce the service life of the cooling flow channel, or so as not to bring negative effects to the cooling effect.

[0148] The first shell 114 is further provided with a fixing portion 153 for fixing the first shell 114 and the cover plate 150, or for fixing the cooling device 100 and the second shell 210 of the cooling system 200. The fixing portion 153 can be in the form of a hole as shown in Figure 7 、 Figure 7 , and then fixed by screwing.

[0149] Further, a partition plate 113 is arranged in the cooling flow channel 110 to form at least two sub-flow channels that are in communication with each other.

[0150] The partition plate 113 is connected to the first shell 114 at one side, and at least one side of the partition plate 113 is not connected to the inner wall of the first shell 114, thereby forming the communication between the two sub-flow channels. The partition plate 113 is detachably connected or fixedly connected to the first shell 114, and the fixed connection includes integral connection and connection by a fixed connection method, such as welding.

[0151] The cooling flow channel 110 is divided into a first sub-flow channel 111 and a second sub-flow channel 112 by the partition plate 113. As shown in Figure 8 、 Figure 7 , the flow channel inlet 151 is in communication with the first sub-flow channel 111, and the flow channel outlet 152 is in communication with the second sub-flow channel 112. It can also be that the flow channel inlet 151 is in communication with the second sub-flow channel 112, and the flow channel outlet 152 is in communication with the first sub-flow channel 111.

[0152] Further, the adjusting device 140 is arranged at the communication position of the two sub-flow channels in communication with each other, so as to adjust the flow resistance between the sub-flow channels. At the same time, the flow resistance of the cooling medium in the two sub-flow channels is further improved, and the efficiency of the cooling adjustment is further improved. The adjusting device 140 at the communication position of the two sub-flow channels and the adjusting device 140 at other positions can be synchronously adjusted and / or asynchronously adjusted according to requirements, so as to achieve more accurate control, a wider cooling range, improve the cooling utilization rate, and avoid waste of cooling capacity.

[0153] As shown in Figure 8 , the flow channel inlet 151 is in communication with the first sub-flow channel 111, and the flow channel outlet 152 is in communication with the second sub-flow channel 112.

[0154] Embodiment Three:

[0155] As shown in Figure 9 ,Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 10 As shown in FIG. 3, the embodiment three of the present application provides a cooling system 200, comprising:

[0156] a to-be-cooled object;

[0157] According to the cooling device 100, the cooling device 100 is used for cooling the to-be-cooled object.

[0158] The cooling capacity of the cooling device 100 is controllable, thereby cooling the to-be-cooled object, enhancing the heat dissipation efficiency and heat dissipation range of the cooling system 200, and improving the reliability of the cooling system 200.

[0159] Further, the cooling system 200 further comprises a second shell 210, and the second shell 210 is used for accommodating the to-be-cooled object.

[0160] The to-be-cooled object is arranged in the second shell 210, and the to-be-cooled object exchanges heat with the cooling medium through the first shell 114, the second shell 210, or the first shell 114 and the second shell 210. The flow resistance of the cooling medium is adjusted through the adjusting device in the cooling flow channel 110, thereby controlling the heat exchange efficiency between the to-be-cooled object and the cooling medium, so that the to-be-cooled object is in a reasonable working range, and the service life of the to-be-cooled object is improved.

[0161] The to-be-cooled object is arranged on one side of the second shell 210, and the cooling device 100 is arranged on the other side of the second shell 210. Preferably, the projection of the to-be-cooled object and the cooling device 100 in at least a certain direction at least partially overlaps, such as shown in FIG. 4, the projection of the to-be-cooled object and the cooling device 100 in the Z direction at least partially overlaps, and preferably the projection of the to-be-cooled object in the Z direction is not greater than the projection of the cooling device 100 in the Z direction, thereby improving the cooling efficiency of the to-be-cooled object. Figure 10

[0162] Further, the first shell 114 and the second shell 210 are integrally arranged, which reduces the heat exchange resistance between the to-be-cooled object and the cooling medium and improves the heat exchange efficiency while ensuring the mutual heat exchange between the to-be-cooled object and the cooling medium. The integral arrangement of the first shell 114 and the second shell 210 is not limited in specific, such as being integrally formed by injection molding or being integrally welded.

[0163] Embodiment four:

[0164] The embodiment four of the present application provides a cooling control method, applied to the cooling system 200, comprising:

[0165] ​Based on the cooling requirements of the object to be cooled, the movement of the blocking structure 120 is controlled to adjust the flow resistance of the cooling medium in the cooling channel 110.

[0166] There can be one or more objects to be cooled. The cooling requirements of different locations of one object to be cooled may be the same or different. The cooling requirements of multiple objects to be cooled may be the same or different.

[0167] The cooling requirements of the object to be cooled include, but are not limited to: the location requiring cooling, the amount of cooling required, the load on the object, and the flow resistance requirements of the cooling system 200. Based on the cooling requirements of the object, the cooling system 200 uses the intelligent control and adjustment device 140 to adjust the structure within the cooling channel 110, thereby regulating the flow resistance of the cooling medium within the channel 110 and minimizing the temperature gradient and flow resistance of the cooling system 200.

[0168] By intelligently identifying and controlling the structure of the cooling channel, precise and controllable cooling of the object to be cooled is achieved, and precise control of the cooling flow rate is realized to ensure that the heat dissipation of the object to be cooled is controllable and the cooling flow rate requirement is minimized, so that the cooling system 200 operates in a low energy consumption load range.

[0169] The main principle of this application is as follows: when the heat generated by the object to be cooled is at its maximum, the flow resistance of the cooling medium in the cooling channel 110 is at its minimum, ensuring sufficient local and overall heat dissipation; as the heat generated by the chip decreases, the flow resistance of the cooling medium in the cooling channel 110 gradually increases to ensure sufficient heat dissipation; as the heat generated by the chip further decreases, the flow resistance of the cooling medium in the cooling channel 110 increases to its maximum; when the flow resistance of the cooling medium in the cooling channel 110 increases to its maximum, such as... Figure 10 to Figure 13 As shown in the Tesla-type reverse flow channel structure, the heat generated by the chip is still decreasing, so the power of the pump body 320 can be gradually reduced. At this time, the cooling flow rate is controlled by both the flow channel structure and the speed of the pump body 320, which improves the cooling efficiency, expands the cooling range, reduces the overall energy consumption, effectively avoids energy waste, and keeps the entire cooling system in the optimal energy utilization state at all times.

[0170] Furthermore, based on the cooling requirements of the object to be cooled, the movement of the blocking structure 120 is controlled to adjust the flow resistance of the cooling medium within the cooling channel 110, including:

[0171] Based on the cooling requirements of the object to be cooled, the angle between the first direction and the second direction is adjusted to adjust the flow resistance of the cooling medium in the cooling channel 110.

[0172] The first direction is the direction in which the blocking structure 120 extends; the second direction is the direction in which the cooling medium flows.

[0173] Based on the cooling demand of the object to be cooled, the angle adjusted by the driving member 130 changes within a preset range to adjust the flow resistance of the cooling medium in the cooling flow channel 110; the angle is the included angle between the blocking structure 120 and the second direction or the cooling plane, the second direction is the direction of the flow of the cooling medium, and the cooling plane is the plane carrying the cooling medium.

[0174] By changing the angle of the blocking structure 120, the form of the cooling flow channel structure is changed. The driving member 130 adjusts the angle of the blocking structure 120 in real time according to the cooling demand of the object to be cooled, thereby controlling the temperature gradient and the flow resistance of the cooling medium in the cooling flow channel 110 to be the smallest, so as to ensure that the heat dissipation of the object to be cooled is controllable and the cooling flow demand is the lowest, so that the cooling system 200 operates in a lower energy consumption load range, realizes precise and controllable cooling of the object to be cooled, and realizes precise control of the cooling flow.

[0175] The angle is the included angle between the blocking structure 120 and the X direction or the cooling plane, which can be realized by rotating the blocking structure 120 on the Y direction or the Z direction, and can also be realized by stretching and contracting the blocking structure 120 on the Y direction and / or the Z direction.

[0176] The angle is the length change of the blocking structure 120 in the Y direction or the Z direction, which can be realized by stretching and contracting the blocking structure 120 on the Y direction and / or the Z direction, and can also be realized by moving the blocking structure 120 on the Y direction and / or the Z direction.

[0177] Further, based on the cooling demand of the object to be cooled, the included angle between the first direction and the second direction is adjusted, including:

[0178] In the case where the cooling demand is greater than the first threshold, the included angle is controlled to be greater than the first preset angle; and / or,

[0179] In the case where the cooling demand is less than or equal to the first threshold, the included angle is controlled to be less than or equal to the first preset angle.

[0180] According to the cooling demand of the object to be cooled, such as the arrangement position, heat generation, load, etc. of the object to be cooled, the angle and / or length of the blocking structure 120 at each position in the cooling flow channel is adjusted to ensure that the cooling capacity of each part is optimal, and the flow is precisely controlled through the cooling flow channel structure and the rotating speed of the pump body 320, thereby improving the stability and reliability of the whole vehicle low-temperature cooling system, ensuring sufficient heat dissipation while reducing cost.

[0181] The cooling demand of the object to be cooled is proportional to the size of the angle. In practical applications, the first threshold value can be multiple or one, and the first angle can also be multiple or one. The value of the first threshold value can be fixed or variable. At the same time, the value of the first angle can be fixed or variable.

[0182] Generally, the number of first threshold values corresponds to the number of first angles. However, if there is an external adjustment factor, the number of first threshold values can be greater than the number of first angles, such as adjusting the flow of cooling medium by the pump body 320 outside the cooling device 100.

[0183] The speed of the pump body 320 can be affected by the power of the pump body 320. As shown in Figure 13 The number of first threshold values is 4, and the number of first angles is 3, as shown in detail below:

[0184] As shown in Figure 12 When the heat generation of the object to be cooled is at the maximum level, the cooling demand of the object to be cooled is the largest, the cooling demand is greater than the first sub-threshold value, the temperature of the object to be cooled is greater than the first temperature limit value, and the driving member 130 controls the blocking structure 120 to form an L-shaped straight channel structure. At this time, the angle is greater than the first sub-angle, the flow resistance of the cooling medium is the smallest, and the local and overall heat dissipation is sufficient. The maximum heat generation of the object to be cooled is, for example, when the heat generation Q of the high-voltage controller is greater than 1500W, or when the heat generation Q of the low-voltage intelligent product working in medium load is greater than 80W, it belongs to the maximum heat generation of the control component 310. The duration of the control component 310 in the maximum load condition is usually short, such as 15s-3min.

[0185] As shown in Figure 11 When the heat generation of the object to be cooled is at the medium level, the cooling demand of the object to be cooled is relatively large, the cooling demand is not greater than the first sub-threshold value, and the temperature of the object to be cooled is not greater than the first temperature limit value. The driving member 130 controls the blocking structure 120 to form an S-shaped flow channel structure. At this time, the angle is not greater than the first sub-angle, the flow resistance of the cooling medium is relatively large, the overall heat dissipation is sufficient, and the system flow resistance is reduced. The medium heat generation of the object to be cooled is, for example, when the heat generation of the high-voltage controller is 800W

[0186] As shown in Figure 10As shown, when the heat generation of the to-be-cooled object is in a small or medium level, the cooling demand of the to-be-cooled object is relatively small, the cooling demand is not greater than the second sub-threshold value, the temperature of the to-be-cooled object is not greater than the second temperature limit value, the driving member 130 controls the blocking structure 120 to form a Z-shaped flow channel structure, at this time, the angle is not greater than the second sub-angle, and the flow resistance of the cooling medium is relatively large, which ensures that the heat dissipation is sufficient and the system flow resistance is minimized. When the heat generation of the high-voltage controller is 300W < Q < 800W, or the heat generation of the low-voltage intelligent product working in a medium load is 20W < Q < 50W, the heat generation of the control component 310 is in a medium level. The second sub-threshold value is less than the first sub-threshold value, the second temperature limit value is less than the first temperature limit value, and the second sub-angle is less than the first sub-angle.

[0187] As shown, Figure 14 When the heat generation of the to-be-cooled object is in a small or medium level, the cooling demand of the to-be-cooled object is relatively small, the cooling demand is not greater than the second sub-threshold value, the temperature of the to-be-cooled object is not greater than the second temperature limit value, the driving member 130 controls the blocking structure 120 to form a Z-shaped flow channel structure, at this time, the angle is not greater than the second sub-angle, and the flow resistance of the cooling medium is relatively large, which ensures that the heat dissipation is sufficient and the system flow resistance is minimized. When the heat generation of the high-voltage controller is 300W < Q < 800W, or the heat generation of the low-voltage intelligent product working in a medium load is 20W < Q < 50W, the heat generation of the control component 310 is in a medium level. The second sub-threshold value is less than the first sub-threshold value, the second temperature limit value is less than the first temperature limit value, and the second sub-angle is less than the first sub-angle.

[0188] When the heat generation of the to-be-cooled object is in a small or medium level, the cooling demand of the to-be-cooled object is relatively small, the cooling demand is not greater than the second sub-threshold value, the temperature of the to-be-cooled object is not greater than the second temperature limit value, the driving member 130 controls the blocking structure 120 to form a Z-shaped flow channel structure, at this time, the angle is not greater than the second sub-angle, and the flow resistance of the cooling medium is relatively large, which ensures that the heat dissipation is sufficient and the system flow resistance is minimized. When the heat generation of the high-voltage controller is 300W < Q < 800W, or the heat generation of the low-voltage intelligent product working in a medium load is 20W < Q < 50W, the heat generation of the control component 310 is in a medium level. The second sub-threshold value is less than the first sub-threshold value, the second temperature limit value is less than the first temperature limit value, and the second sub-angle is less than the first sub-angle.

[0189] Each of the above-mentioned levels can be a range value and / or a point value, such as a maximum level of 80%~100%, 80%~100% or 100%, a middle level of 60%~90%, 70%~90% or 60%~80%, a middle-small level of 40%~60%, 40%~70% or 50%~70%, a small level of 20%~40%, 20%~50% or 30%~40%, and a minimum level of 0%~20% or 0%~30%.

[0190] In addition to the above examples, the cooling flow channel structure can be combined with the rotation speed of the pump body 320 to adjust the resistance of the cooling system in parallel, to ensure sufficient heat dissipation while achieving lower cooling flow, and to reduce the energy consumption of the pump body 320.

[0191] The position of the object to be cooled, the heat load of the chip, and the flow resistance requirement of the cooling system. The driving member 130 adjusts the cooling flow channel structure form, and adjusts the heat dissipation capacity through the cooling flow channel structure form and / or the rotation speed of the pump body 320, and minimizes the temperature gradient and the flow resistance of the cooling system; through active adaptive working condition and cooling flow channel structure form matching control, precise and controllable cooling of the object to be cooled and precise control of the optimal cooling flow are realized; the heat dissipation is controllable and the cooling flow demand is the lowest, so that the cooling system operates in a lower energy consumption load range.

[0192] Further, based on the cooling demand of the object to be cooled, the blocking structure 120 is controlled to move to adjust the flow resistance of the cooling medium in the cooling flow channel 110, including:

[0193] Based on the cooling demand of the object to be cooled, the blocking structure 120 is adjusted to stretch or move in the first direction to adjust the flow resistance of the cooling medium in the cooling flow channel 110. The first direction is the direction in which the blocking structure 120 extends.

[0194] By stretching or moving the blocking structure 120 in the Y direction and / or the Z direction, the cooling flow channel structure form is changed. The driving member 130 adjusts the angle change of the blocking structure 120 in real time according to the cooling demand of the cooling object, and then controls the temperature gradient and the flow resistance of the cooling medium in the cooling flow channel 110 to be the smallest, to ensure that the heat dissipation of the object to be cooled is controllable and the cooling flow demand is the lowest, so that the cooling system 200 operates in a lower energy consumption load range, realizes precise and controllable cooling of the object to be cooled, and realizes precise control of the cooling flow.

[0195] Stretching is the stretching or contraction movement of the blocking structure 120 in the Y direction and / or the Z direction. It can be realized by stretching or contraction movement of the blocking structure 120 in the Y direction, or by stretching or contraction movement of the blocking structure 120 in the Z direction, or by stretching or contraction movement of the blocking structure 120 in the Y direction and the Z direction.

[0196] The movement is the change of the length of the blocking structure 120 in the Y direction and / or the Z direction within the cooling flow channel 110. The length of the blocking structure 120 within the cooling flow channel 110 is changeable, or the blocking structure 120 is not always located within the cooling flow channel 110, and the blocking structure 120 exists in the moment of being partially located within the cooling flow channel 110. That is, the blocking structure 120 within the cooling flow channel 110 is the effective part of truly adjusting the flow resistance of the cooling medium, which can be called the effective part of the blocking structure 120.

[0197] No matter whether the blocking structure 120 adopts the contraction and / or movement scheme, it itself is to realize the adjustment of the length or volume of the effective part, and then realize the adjustment of the flow resistance within the cooling flow channel.

[0198] The cooling demand is the heat generation of the object to be cooled.

[0199] Embodiment five:

[0200] The embodiment five of the present application provides a storage medium, which comprises a stored program, wherein the program controls a device where the storage medium is located to execute the cooling control method when the program is running.

[0201] Embodiment six:

[0202] The embodiment six of the present application provides a computer program product, which comprises a computer program, and the computer program realizes the steps of the cooling control method when the computer program is executed by a processor.

[0203] Embodiment seven:

[0204] The embodiment seven of the present application provides a controller 300, which comprises a control assembly 310 and the cooling device 100, and the control assembly 310 and the cooling device 100 can mutually transfer heat.

[0205] With the development of the integration of the controller, the heat flow density of the controller is increasing day by day, and higher requirements are put forward for the cooling of the control assembly 310. When the control assembly 310 is in the maximum load working condition, the heat generation of the control assembly 310 is the largest. For example, the heat generation Q of the high-voltage controller is greater than 1500W, or the heat generation Q of the low-voltage intelligent product working in the medium load is greater than 80W, which belongs to the maximum heat generation of the control assembly 310. The duration of the control assembly 310 in the maximum load working condition is usually short, such as 15 seconds-3 minutes.

[0206] The cooling medium flows through the cooling flow channel via the flow channel inlet 151, passes the blocking structure 120, and preferably passes the protruding structure 124 on the surface of the blocking structure 120 to generate turbulence and increase the heat dissipation area. According to the load size and / or heat generation of the control assembly 310, the driving member 130 drives the blocking structure 120 to form various flow channel structure forms, so as to ensure that the local and overall heat dissipation is sufficient. The flow channel inlet 151, the cooling flow channel 110, the flow channel outlet 152, and the external cooling branch form a cooling loop of the control assembly 310. The cooling flow channel is enclosed by the shell and the cover plate 150 to form a real-time, continuous, and stepless controller 300. The turbulence form in the cooling flow channel of the controller 300 is adjustable.

[0207] Figure 14 The controller is schematically shown in the figure, and at least a pump body 320 is arranged in the external cooling branch. Figure 10

[0208] Further, the second shell 210 is arranged to connect the control assembly 310 and the cooling device 100. The control assembly 310 and the cooling device 100 are in heat transfer with each other through the second shell 210. The second shell 210 is preferably made of a material with good heat conduction performance, such as metal.

[0209] The control assembly 310 is arranged in the second shell 210. The control assembly 310 is in heat exchange with the cooling medium through the first shell 114, the second shell 210, or both the first shell 114 and the second shell 210. The flow resistance of the cooling medium is adjusted by the adjusting device in the cooling flow channel 110, so as to control the heat exchange efficiency between the control assembly 310 and the cooling medium. The control assembly 310 is in a reasonable working range, and the service life of the control assembly 310 is improved.

[0210] The control assembly 310 is arranged on one side of the second shell 210, and the cooling device 100 is arranged on the other side of the second shell 210. Preferably, the projection of the control assembly 310 and the cooling device 100 in at least one direction at least partially overlaps, as shown in the figure. The projection of the control assembly 310 and the cooling device 100 in the Z direction at least partially overlaps, and preferably the projection of the control assembly 310 in the Z direction is not greater than the projection of the cooling device 100 in the Z direction, so as to improve the cooling efficiency of the control assembly 310. Figure 15

[0211] The first shell 114 and the second shell 210 are integrally arranged. In the case of ensuring the heat exchange between the control assembly 310 and the cooling medium, the heat exchange resistance between the control assembly 310 and the cooling medium is reduced, and the heat exchange efficiency is improved. The first shell 114 and the second shell 210 are integrally arranged in a manner not limited, such as being integrally formed by injection molding or being integrally welded. ​​

[0212] Embodiment eight:

[0213] As ​ shown, embodiment eight of the present application provides a vehicle comprising the adjusting device 140, or the cooling device 100, or the cooling system 200, or the controller 300, or performing the cooling system control method.

[0214] In the case of the control component 310 being a chip or power module on the vehicle, when the control component 310 is at maximum load, the whole vehicle is usually in a starting working condition or a steep slope working condition.

[0215] The present patent first controls the blocking structure 120 to actively partition the overall cooling flow channel or form a main flow channel with different structural shapes, and performs real-time, continuous, and stepless mode matching of the cooling system according to the position, working condition, and load of the control component 310. The cooling flow channel with different structural forms and / or different angles is automatically and continuously adjusted by controlling the driving member 130 to form, so as to ensure that the heat dissipation amount is sufficient and the water channel flow resistance is overall small. The cooling system resistance can also be adjusted in parallel through the pump body 320 speed and the cooling flow channel structure, so as to realize a lower cooling flow while ensuring sufficient heat dissipation amount. At the same time, this can also reduce the system pipeline pressure load, enhance the system cooling capacity adjustment range, and improve the energy efficiency and reliability of the low-temperature cooling system. The present patent actively and adaptively adjusts the cooling flow channel through a real-time, continuous, and stepless adjustable cooling system, so as to ensure that the cooling system matches the control mode with the heat dissipation working condition, heat source position, and load, and greatly improves the reliability of the cooling system.

[0216] Although the embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present application, and those of ordinary skill in the art can make changes, modifications, replacements, and variations to the above embodiments within the scope of the present application.
