Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to a cooling structure and a vehicle. Background Technology

[0002] When using a cooling structure to cool heat-generating components, especially when cooling domain controllers, the cooling channels of the cooling structure cannot be set to be continuous due to space and other factors. This results in unavoidable bends in the cooling channels, which cause the cooling medium to flow poorly in the bend areas of the cooling channels and easily stagnate, leading to low cooling efficiency of the cooling structure for heat-generating components. Utility Model Content

[0003] In view of this, this application provides a cooling structure that at least solves the problem of low cooling efficiency for heat-generating components. This application also provides a vehicle including the aforementioned cooling structure.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] A cooling structure for exchanging heat with a heat-generating element, the cooling structure including a flow channel in which a cooling medium for exchanging heat with the heat-generating element flows;

[0006] The flow channel is equipped with a flow-dispersing element, which includes multiple circumferentially distributed flow-dispersing blades. By rotating the flow-dispersing element, the flow-dispersing blades agitate the cooling medium, thereby increasing the turbulence of the cooling medium.

[0007] Optionally, the inner wall of the flow guiding channel is a wavy wall extending along the axial direction of the flow guiding channel.

[0008] Optionally, the baffle is disposed at the inlet end of the flow guiding channel.

[0009] Optionally, the axial direction of the deflector is the same as the flow direction of the cooling medium, and the deflector blade has a force-bearing surface that is inclined relative to the flow direction of the cooling medium so that the deflector blade rotates under the drive of the flowing cooling medium.

[0016] The cooling structure provided in this application includes a flow guide channel in which a cooling medium flows to exchange heat with a heat-generating component. The flow guide channel is equipped with a turbulence-inducing component, which comprises multiple circumferentially distributed turbulence-inducing blades. Rotation of the turbulence-inducing component causes the blades to agitate the cooling medium, thereby increasing its turbulence. This arrangement, by increasing the turbulence of the cooling medium within the flow guide channel, enhances the flowability of the cooling medium in the bends of the flow guide channel, preventing obstructed flow and reducing or even eliminating stagnation of the cooling medium in these areas.

[0028] This application provides a cooling structure that at least solves the problem of low cooling efficiency for heat-generating components. This application also provides a vehicle including the aforementioned cooling structure.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] like Figures 1 to 5 As shown in the figure, this application embodiment provides a cooling structure 1, which is used to exchange heat with a heat-generating component 2 to cool the heat-generating component 2. It should be noted that the heat-generating component 2 is not limited here; an exemplary heat-generating component 2 can be a battery, controller, or other components that need to be cooled. The cooling structure 1 mainly includes a flow channel 11, in which a cooling medium that exchanges heat with the heat-generating component 2 flows. The cooling medium circulates within the flow channel 11 to continuously exchange heat with the heat-generating component 2 to achieve cooling of the heat-generating component 2. The flow channel 11 is equipped with a flow-dispersing element 12, which includes multiple circumferentially distributed flow-dispersing blades 121. By rotating the flow-dispersing element 12, the flow-dispersing blades 121 agitate the cooling medium. The rotation of the flow-dispersing blades 121 can change the flow direction of the cooling medium in the flow channel 11, thereby increasing the degree of turbulence of the cooling medium flowing in the flow channel 11. In other words, it makes the movement of particles in the cooling medium in the flow channel 11 more chaotic and disordered, thereby reducing or even avoiding the retention of the cooling medium in the bend area of ​​the flow channel 11, and improving the heat exchange efficiency between the cooling medium and the heat-generating element 2 in the flow channel 11.

[0031] It should be noted that the rotation direction of the baffle blades 121 of the baffle member 12 is not limited to the flow direction of the cooling medium. For example: the rotation direction of the baffle blades 121 of the baffle member 12 can be perpendicular to the flow direction of the cooling medium; the rotation direction of the baffle blades 121 of the baffle member 12 can also form an acute angle with the flow direction of the cooling medium; the rotation direction of the baffle blades 121 of the baffle member 12 can also be parallel to the flow direction of the cooling medium.

[0032] It should also be noted that the number of deflectors 12 is not limited here. One or more deflectors 12 can be provided in the flow channel 11. Furthermore, the number of deflectors 121 provided on a single deflector 12 is not limited. Preferably, multiple deflectors 121 are provided, and multiple deflectors 121 are provided at equal intervals in the circumference of the deflector 12. In this way, when the deflectors 121 rotate, the vibration and noise caused by the dynamic balance problem of the deflectors 121 during rotation will be reduced.

[0033] It should also be noted that the form of the cooling medium is not limited here; the cooling medium can be a liquid cooling medium, a gaseous cooling medium, or a gas-liquid mixture. For example, the cooling medium can be water, Freon, liquid nitrogen, carbon dioxide, etc.

[0034] The cooling structure 1 described above, by setting the flow-deflecting element 12, increases the degree of turbulence of the cooling medium in the flow-guiding channel 11, thereby improving the flowability of the cooling medium in the bending area of ​​the flow-guiding channel 11, avoiding poor flow of the cooling medium in the bending area of ​​the flow-guiding channel 11, reducing or even avoiding the stagnation of the cooling medium in the bending area, improving the circulation efficiency of the cooling medium in the flow-guiding channel 11, and thus improving the cooling efficiency of the cooling structure 1 for the heat-generating element 2.

[0035] In some embodiments, please refer to Figure 3 and Figure 4 The flow-deflecting element 12 is disposed at the inlet end of the flow-guiding channel 11. Thus, when the cooling medium enters the flow-guiding channel 11, the flow-deflecting element 12 immediately agitates the flowing medium, increasing the turbulence of the medium and ensuring its smooth flow within the channel. This further prevents the cooling medium from remaining in the bend section 16 of the flow-guiding channel 11, thereby further improving the heat exchange efficiency between the cooling structure 1 and the heat-generating element 2.

[0036] In addition, the flow deflector 12 can also be disposed at other locations in the flow guide channel 11. For example, the flow deflector 12 can also be disposed in the middle part of the flow guide channel 11. Preferably, the flow deflector 12 is disposed in the upstream area of ​​the bend section 16 of the flow guide channel 11. This can increase the degree of turbulence of the cooling medium flowing to the bend section 16, thereby reducing or even avoiding the retention of the cooling medium in the bend section 16.

[0037] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4 The axial direction of the baffle 12 is the same as the flow direction of the cooling medium; that is, the rotation direction of the baffle blades 121 of the baffle 12 is perpendicular to the flow direction of the cooling medium. The baffle blades 121 have a force-bearing surface 1211 that is inclined relative to the flow direction of the cooling medium, so that the baffle blades 121 rotate under the drive of the flowing cooling medium. Thus, when the flowing cooling medium reaches the location of the baffle 12, the cooling medium impacts the force-bearing surface 1211 of the baffle blades 121, causing the baffle blades 121 to rotate due to the impact force of the cooling medium, thereby agitating the cooling medium and increasing its turbulence.

[0038] It should be noted that the flow direction of the cooling medium is... Figure 1 The direction indicated by the middle arrow A.

[0039] In addition, the rotation of the baffle blade 121 can also be achieved in other ways, such as: a motor is installed inside the baffle 12, and the baffle blade 121 installed on the baffle 12 is driven by the motor to achieve the rotation of the baffle blade 121, thereby increasing the degree of turbulence of the cooling medium in the guide channel 11.

[0040] Based on the above embodiment, the rotation axis of the baffle 12 is located on the axis of the guide channel 11. That is, the rotation axis of the baffle 12 is located at the radial center of the guide channel 11, that is, the baffle 12 is centrally located within the guide channel 11. In this way, when the rotating cooling medium flows towards the baffle 12, the baffle 12 can apply a more uniform force to the cooling medium in the radial direction of the guide channel 11, thereby balancing the force in the cooling medium distribution area and improving the uniformity and stability of the cooling medium flow.

[0041] In some embodiments, the angle between the force-bearing surface 1211 and the flow direction of the cooling medium is R, where R satisfies: 5°≤R≤30°. On the one hand, if the angle between the force-bearing surface 1211 and the flow direction of the cooling medium is too small, the impact force on the force-bearing surface 1211 when the flowing cooling medium impacts the baffle 121 is small, resulting in a smaller rotation amplitude of the baffle 121 and a smaller increase in the turbulence of the cooling medium by the baffle 12. On the other hand, if the angle between the force-bearing surface 1211 and the flow direction of the cooling medium is too large, the impact force on the force-bearing surface 1211 when the flowing cooling medium impacts the baffle 121 is large, resulting in a larger rotation amplitude of the baffle 121, which in turn generates greater resistance to the cooling medium and affects the flow velocity of the cooling medium. This configuration ensures both the rotation amplitude of the turbulence blades 121 to maintain the degree of turbulence in the cooling medium and avoids excessive resistance generated by the cooling medium through the turbulence blades 121, thus ensuring the flow velocity of the cooling medium.

[0042] For example, the angle R between the force-bearing surface 1211 and the flow direction of the cooling medium can be 5°, 6°, 8°, 10°, 15°, 20°, 25°, 28°, 29°, 30°, etc.

[0043] In some embodiments, please refer to Figure 3 and Figure 4 The cooling structure 1 includes a support member 13 that supports the flow-deflecting element 12. The support member 13 is connected to the flow-guiding channel 11. By providing the support member 13, the stability of the support for the flow-deflecting element 12 is ensured. Furthermore, the cross-sectional area of ​​the support member 13 increases gradually in the direction of cooling medium flow. Thus, when the cooling medium flows through the location of the support member 13, the resistance generated by the support member 13 to the flow of the cooling medium is reduced due to the gradually expanding structure of the support member 13 in the direction of cooling medium flow, thereby increasing the flow rate of the cooling medium.

[0044] Furthermore, based on the above embodiments, the cross-section of the support member 13 is a conical surface. In this way, during the flow of the cooling medium, the resistance generated by the support member 13 to the cooling medium can be further reduced, the flow rate of the cooling medium can be further increased, and the heat exchange efficiency between the cooling structure 1 and the heat-generating element 2 can be improved.

[0045] Because the cooling medium has poor flowability near the bend 16 of the guide channel 11 during its flow, the heat exchange efficiency between the cooling medium flowing through the bend 16 and the heat-generating element 2 is low. Therefore, in some embodiments, please refer to... Figure 1 , Figure 2 and Figure 5The inner wall of the flow channel 11 is a wavy wall extending along the axial direction of the flow channel 11. In this way, when the cooling medium flows through the wavy wall of the flow channel 11, it can cause the cooling medium to flow turbulently, that is, increase the degree of turbulence of the cooling medium. By further increasing the degree of turbulence of the cooling medium, the retention of the cooling medium in the bend section 16 of the flow channel 11 is reduced or even avoided, thereby improving the heat exchange efficiency of the cooling structure 1 to the heat-generating component 2.

[0046] It should be noted that one or more walls of the flow channel 11 can be set as wavy walls, or all walls of the flow channel 11 can be set as wavy walls.

[0047] In some embodiments, please refer to Figure 1 and Figure 5 Multiple heat dissipation columns 14 are provided within the flow channel 11. The heat dissipation columns 14 are thermally connected to the heat-generating element 2. By providing the heat dissipation columns 14, the contact area between the cooling structure 1 and the heat-generating element 2 can be cooled, thereby improving the heat exchange effect between the cooling structure 1 and the heat-generating element 2. Furthermore, the cross-sectional profile of the heat dissipation columns 14 is streamlined. When the cooling medium flows within the flow channel 11, the streamlined cross-sectional profile of the heat dissipation columns 14 further reduces the resistance to the flow of the cooling medium, thereby improving the heat exchange efficiency between the cooling medium and the heat-generating element 2.

[0048] In some embodiments, please refer to Figure 1 and Figure 5 Multiple heat dissipation columns 14 are spaced apart along the axial direction of the flow channel 11; and / or, multiple heat dissipation columns 14 are spaced apart along the radial direction of the flow channel 11. This embodiment includes three implementation methods: multiple heat dissipation columns 14 are spaced apart along the axial direction of the flow channel 11; multiple heat dissipation columns 14 are spaced apart along the radial direction of the flow channel 11; and multiple heat dissipation columns 14 are spaced apart both along the axial and radial directions of the flow channel 11. In other words, the heat dissipation columns 14 are alternately arranged in the direction of cooling medium flow. This arrangement further agitates the flow state of the cooling medium as it flows within the flow channel 11, allowing the high-temperature cooling medium heated by the shell to mix fully with the unheated low-temperature cooling medium within the flow channel 11. This allows more low-temperature cooling medium to participate in the heat exchange with the shell, thereby increasing the heat exchange efficiency of the cooling structure 1.

[0049] In some embodiments, please refer to Figure 1The flow guiding channel 11 includes straight sections 15 at both ends and a bent section 16 in the middle. The straight sections 15 are the areas where the flow guiding channel 11 is in a straight state, while the bent section 16 is the area where the flow guiding channel 11 bends. By configuring the flow guiding channel 11 with straight sections 15 at both ends and a bent section 16 in the middle, and by configuring the flow guiding channel 11 as a U-shaped structure, the number of bends in the flow guiding channel 11 can be reduced, thus reducing the flow resistance of the flow guiding channel 11 and increasing the flow velocity of the cooling medium within the flow guiding channel 11, thereby improving the heat exchange efficiency of the flow guiding structure for the heat-generating element 2.

[0050] In some embodiments, please refer to Figure 1 and Figure 5 The cooling structure 1 also includes an inlet pipe 17 connected to one end of the flow channel 11 and an outlet pipe 18 connected to the other end of the flow channel 11. The cooling medium flows into the flow channel 11 through the inlet pipe 17 and flows out of the flow channel 11 through the outlet pipe 18.

[0051] This application also provides a vehicle including a heat-generating element 2 and a cooling structure 1 as described in any of the above claims, wherein the heat-generating element 2 is a domain controller. For example, the domain controller in the vehicle may be a cockpit domain controller, a driver assistance domain controller, a body domain controller, etc.
