[0028] Embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary.

[0029] Reference will be made below to Figures 1-5 to describe the diverter structure 100 according to an embodiment of the present utility model, which can maintain a certain pressure difference between the heat exchange medium at the liquid inlet channel 11 and the liquid outlet channel 12, thereby increasing the pressure of the heat exchange medium in the heat exchange structure 200, increasing the evaporation temperature of the heat exchange medium, and further reducing the temperature difference between the battery cells at different positions in the battery pack, avoiding the problem of increased inconsistency between the battery cells.

[0030] In conjunction with Figures 1-5As shown, the diverter structure 100 according to the first aspect embodiment of the present utility model includes a diversion assembly 1 and a throttling assembly 2. Among them, the diversion assembly 1 can divert the heat exchange medium (that is, the heat exchange medium), and the throttling assembly 2 can control the system pressure by adjusting the flow rate of the heat exchange medium.

[0031] Specifically, the diversion assembly 1 is provided with an inlet liquid channel 11 and a plurality of outlet liquid channels 12. The inlet liquid channel 11 and the plurality of outlet liquid channels 12 are arranged at intervals. The inlet liquid channel 11 is used to convey the heat exchange medium to the heat exchange structure 200, and the outlet liquid channel 12 is used to receive the heat exchange medium conveyed by the heat exchange structure 200. The throttling assembly 2 is arranged in the outlet liquid channel 12 and selectively opens the outlet liquid channel 12 under the action of pressure. Among them, the heat exchange structure 200 can be a direct cooling plate, and the direct cooling plate is usually arranged on the upper part of the battery pack.

[0032] Specifically, the inlet end of the heat exchange structure 200 is connected to the inlet liquid channel 11 of the diversion assembly 1. The heat exchange medium can enter the interior of the heat exchange structure 200 through the inlet liquid channel 11 on the diversion assembly 1, and the plurality of outlet liquid channels 12 on the diversion assembly 1 can allow the heat exchange medium to be diverted from the interior of the heat exchange structure 200 to the throttling assembly 2 according to the flow path layout requirements inside the heat exchange structure 200, so as to facilitate the continuous heat exchange work of the heat exchange medium on the heat exchange structure 200.

[0033] Among them, the diverter structure 100 can control the flow rate of the heat exchange medium entering each outlet liquid channel 12, reduce the pressure of the heat exchange medium, and can also adjust the distribution of the heat exchange medium according to the flow path layout requirements, thereby improving the flexibility and adaptability of the flow path.

[0034] Furthermore, the throttling assembly 2 in the outlet liquid channel 12 will open the outlet liquid channel 12 after being subjected to a certain heat exchange medium pressure. This will enable the heat exchange medium inside the heat exchange structure 200 to achieve the effect of communicating with the outside world, thereby increasing the pressure of the heat exchange medium inside the heat exchange structure 200, increasing the evaporation temperature of the heat exchange medium, and further reducing the temperature difference between the heat exchange structure 200 and the battery cell, ensuring the cooling uniformity of the battery cell. The throttling assembly 2 can keep a certain pressure difference at the inlet and outlet of the heat exchange structure 200 for the heat exchange medium, that is, the throttling assembly 2 can only open the outlet liquid channel 12 after being subjected to a certain pressure, so as to effectively improve the cooling effect of the battery cell and the balance of the temperature difference between different positions of the battery cell, and further ensure the increased consistency of the battery cell and extend the service life of the battery pack.

[0035] Therefore, by setting up the diverter structure 100, it is convenient for the heat exchange medium to enter the heat exchange structure 200 from an inlet channel 11 and then be diverted to multiple outlet channels 12 according to the flow path layout requirements, thereby improving the flexibility of the flow path; it is also possible to maintain a certain pressure difference between the heat exchange medium at the inlet channel 11 and the outlet channel 12, thereby increasing the pressure of the heat exchange medium in the heat exchange structure 200, increasing the evaporation temperature of the heat exchange medium, and then reducing the temperature difference of the battery cells at different positions in the battery pack, avoiding the problem of increased inconsistency between the battery cells.

[0036] According to some optional embodiments of the present invention, combined with Figure 4 and Figure 5 As shown, the throttling assembly 2 includes a throttling member 21 and an elastic member 22, the throttling member 21 is disposed in the liquid outlet channel 12, the elastic member 22 is disposed in the liquid outlet channel 12, and the elastic member 22 abuts between the wall of the liquid outlet channel 12 and the throttling member 21, and the throttling member 21 closes the liquid outlet channel 12 under the elastic force of the elastic member 22. For example, the elastic member 22 can be a spring, but is not limited thereto.

[0037] Among them, the elastic member 22 undergoes elastic deformation and generates an elastic force, which can provide an elastic reset force away from the liquid outlet direction to the throttling member 21. For example, the throttling member 21 is simultaneously subjected to the elastic force from the elastic member 22 and the heat exchange medium pressure of the heat exchange medium, and the two forces are in opposite directions. When the heat exchange medium pressure on the throttling member 21 is less than the elastic force of the elastic member 22, the throttling member 21 will not move along one side of the liquid outlet direction, thereby achieving a state of keeping the liquid outlet channel 12 closed; for another example, when the heat exchange medium pressure on the throttling member 21 is greater than the elastic force of the elastic member 22, the throttling member 21 will move along one side of the liquid outlet direction, thereby achieving the effect of opening the liquid outlet channel 12, thereby enabling the heat exchange medium inside the heat exchange structure 200 to communicate with the outside of the diverter structure 100.

[0038] Specifically, combined Figure 4 and Figure 5 As shown, the liquid outlet channel 12 is configured with a conical section 121 with a cross section increasing in the liquid outlet direction, and the throttling member 21 and the elastic member 22 are arranged in the conical section 121 .

[0039] It can be understood that the cross section of the conical section 121 in the liquid outlet direction gradually increases, so that the space requirement for accommodating the throttling member 21 and the elastic member 22 can be defined.

[0040] Among them, the throttle member 21 is configured as a sphere, and the diameter of the sphere is greater than the minimum diameter of the conical section 121 and less than the maximum diameter of the conical section 121. On the one hand, this can enable the conical section 121 to form a limiting effect on the throttle member 21 and the elastic member 22 in the direction away from the liquid outlet, preventing the two from moving to an undesired position in the liquid outlet channel 12, thereby ensuring the effect that the throttle assembly 2 can selectively open the liquid outlet channel 12. On the other hand, it can also facilitate the accommodation of the throttle member 121 in the conical section 121, thus facilitating assembly and further improving the rationality of its layout.

[0041] Moreover, the throttle member 21 is configured as a sphere, and the spherical structure can evenly distribute the force, resulting in high structural strength and stability, and it is not easy to have stress concentration at a certain point. In addition, the curve on the outer surface of the sphere is smooth and symmetric, which allows connection from multiple directions, increasing the connection flexibility and versatility of the structure, thereby ensuring that the throttle member 21 can stably maintain contact with the wall of the conical section 121 under the condition that the liquid outlet channel 12 cannot be opened.

[0042] Furthermore, as shown in Figures 3-5 the flow splitting assembly 1 includes a first flow splitter 13 and a second flow splitter 14. The second flow splitter 14 is connected to the first flow splitter 13, and the liquid inlet channel 11 extends in the first flow splitter 13 and the second flow splitter 14. Among them, the liquid outlet channel 12 is configured as a first cylindrical section 122 and a second cylindrical section 123, and the conical section 121 is connected between the first cylindrical section 122 and the second cylindrical section 123. The first cylindrical section 122 and the conical section 121 are located in the first flow splitter 13, and the second cylindrical section 123 is located in the second flow splitter 14.

[0043] That is to say, partial segments of the liquid inlet channel 11 and the liquid outlet channel 12 extend in both the first flow splitter 13 and the second flow splitter 14. The first cylindrical section 122 and the conical section 121 of the liquid outlet channel 12 are both located in the first flow splitter 13, and along the liquid outlet direction, the first cylindrical section 122, the conical section 121, and the second cylindrical section 123 are sequentially connected. Since the conical section 121 is only provided on one side of the first flow splitter 13 close to the second flow splitter 14, this can facilitate the processing and manufacturing of the conical section 121, thereby improving the manufacturing efficiency.

[0044] Specifically, as shown in Figures 3-5 a ring-shaped boss 141 surrounding the second cylindrical section 123 is provided on the end face of the second flow splitter 14 facing the first flow splitter 13, and the elastic member 22 is sleeved on the ring-shaped boss 141.

[0045] Among them, with the above arrangement, the ring-shaped boss 141 can form a limiting effect on the elastic member 22, thereby improving the position stability of the elastic member 22, preventing the risk of the elastic member 22 from moving around, and further ensuring that the elastic member 22 continuously maintains a normal elastic force effect on the throttle member 21.

[0046] Furthermore, in combination with Figure 5 as shown, the height of the annular boss 141 is h1, and h1 satisfies the relationship: 0.5 mm ≤ h1 ≤ 1.5 mm.

[0047] That is to say, the height of the annular boss 141 is relatively small. In this way, on the premise of forming a stable limiting effect on the elastic member 22, additional material consumption can be avoided, thereby improving economy. For example, the height h1 of the annular boss 141 can be 0.5 mm, 0.7 mm, 1 mm, 1.2 mm, and 1.5 mm, and is not limited thereto.

[0048] Specifically, in combination with Figure 3 and Figure 4 as shown, the second diverter 14 is provided with a liquid inlet 142 and a liquid outlet 143. There is one liquid inlet 142 which is communicated with the liquid inlet channel 11, and there is one liquid outlet 143 which is communicated with a plurality of liquid outlet channels 12.

[0049] It can be understood that one liquid inlet 142 is communicated with the liquid inlet channel 11, so as to ensure the pressure and flow velocity of the heat exchange medium when the heat exchange medium enters the interior of the heat exchange structure 200. The plurality of liquid outlet channels 12 can facilitate the heat exchange medium inside the heat exchange structure 200 to flow out of the heat exchange structure 200 along different liquid outlet paths. And the plurality of liquid outlet channels 12 are communicated with one liquid outlet 143, so that the heat exchange medium in the plurality of liquid outlet channels 12 can be converged to one liquid outlet 143. In this way, the structure of the liquid outlet channels 12 can be simplified, the number and layout complexity of the liquid outlet 143 can be reduced, and the pressure and rate of the heat exchange medium at the liquid outlet 143 can be increased after the convergence of the plurality of liquid outlet channels 12, thereby accelerating the circulating flow velocity of the heat exchange medium.

[0050] Furthermore, in combination with Figure 5 as shown, the diverter structure 100 further includes a seal 3. The seal 3 is arranged in the conical section 121, and the seal 3 is used for sealing cooperation with the throttle member 21. For example, the seal 3 can be a rubber ring, and is not limited thereto.

[0051] That is to say, the seal 3 is installed and fitted on the wall of the conical section 121, and the seal 3 is in sealing cooperation with the throttle member 21. In this way, the risk that the heat exchange medium leaks out from the gap between the throttle member 21 and the wall of the conical section 121 can be prevented, so as to ensure that the pressure of the heat exchange medium and the evaporation temperature of the heat exchange medium in the heat exchange structure 200 are relatively high, thereby reducing the temperature difference between the battery cells at different positions in the battery pack and avoiding the problem of increased inconsistency between the battery cells.

[0052] In combination with Figure 1 and Figure 2As shown in the figure, the battery pack according to the second aspect embodiment of the present invention includes a plurality of battery cells, the shunt structure 100 of the above embodiment, and the heat exchange structure 200. The shunt structure 100 is located at one end of the plurality of battery cells, and the heat exchange structure 200 is disposed on one side of the plurality of battery cells. The heat exchange structure 200 is respectively communicated with the liquid inlet channel 11 and the liquid outlet channel 12.

[0053] Specifically, the shunt structure 100 can be located at one end of the plurality of battery cells (such as the front end, the rear end, not limited thereto), so that the spatial layout can be more regular, thereby improving the rationality of the spatial layout.

[0054] Specifically, the heat exchange structure 200 is adjacent to the battery cells, and the heat at the battery cells is conducted to the heat exchange structure 200. The heat exchange medium can flow into the heat exchange structure 200 after passing through the liquid inlet channel 11 of the shunt structure 100. After the heat exchange medium contacts the heat exchange structure 200, heat exchange occurs, so that the heat on the battery cells can be taken away, thereby forming a cooling effect on the battery cells.

[0055] For example, when the cooling system is not working, the throttle member 21 is in close fit with the seal member 3 under the elastic support of the elastic member 22, and at this time, the liquid outlet channel 12 is in a closed state. When the cooling system is working, when a certain pressure difference is formed between the heat exchange media at the throttle member 21 in the liquid inlet channel 11 and the liquid outlet channel 12, the elastic member 22 is compressed under the action of the pressure, and the throttle member 21 is separated from the liquid outlet channel 12. At this time, the liquid outlet channel 12 is in an open state.

[0056] The vehicle according to the third aspect embodiment of the present invention includes the battery pack of the above embodiment. Thus, the vehicle with this battery pack can extend the battery pack life and improve the safety of the battery pack, thereby enhancing the market competitiveness of the vehicle.
