Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Example 1: Reference Figure 1-4The illustrated device is a flow-adaptive intelligent temperature control system based on a gearbox water-cooling system. It includes a cooling tank 1, which holds the coolant and provides space for the heat dissipation process. A tiered heat dissipation assembly is installed inside the cooling tank 1. This assembly includes a heat-conducting plate 6 fixedly connected to the inner side of the cooling tank 1. The heat-conducting plate 6 transfers heat from the coolant to the inner wall of the cooling tank 1, assisting in heat dissipation. A first heat-conducting baffle 11 is fixedly connected to the inner side of the cooling tank 1. This baffle divides the interior of the cooling tank 1 into different areas, guiding the coolant flow path, extending the coolant heat dissipation time, and improving heat dissipation efficiency. A second heat-conducting baffle 12 is also fixedly connected to the inner side of the cooling tank 1. This baffle also serves to divide the area and guide the coolant flow, enhancing the heat dissipation effect. A first cooling channel 8 is provided between the heat-conducting plate 6 and the first heat-conducting baffle 11, providing an initial heat dissipation channel for the coolant. A second cooling channel 9 is provided between the first heat-conducting baffle 11 and the second heat-conducting baffle 12, where the coolant further dissipates heat, and the temperature of the coolant decreases further after two heat dissipation processes. A third cooling channel 10 is provided between the second heat-conducting baffle 12 and the inner wall of the cooling tank 1, where the coolant completes the final stage of heat dissipation, ensuring that the temperature of the coolant flowing out of the cooling tank 1 reaches the ideal state. A first connecting pipe 14 is provided through the outer side of the first heat-conducting baffle 11, with both ends of the first connecting pipe 14 extending to the first cooling channel 8. The second cooling channel 9 connects the first cooling channel 8 and the second cooling channel 9, allowing the coolant to flow between the two channels and achieve tiered heat dissipation. A second connecting pipe 15 is provided through the outer side of the second heat-conducting baffle 12. The two ends of the second connecting pipe 15 extend into the second cooling channel 9 and the third cooling channel 10, respectively, to connect the second cooling channel 9 and the third cooling channel 10, ensuring that the coolant flows sequentially throughout the tiered heat dissipation assembly and continuously dissipates heat. A first slot 17 adapted to the first connecting pipe 14 is provided on the outer side of the first heat-conducting baffle 11, which facilitates the installation and fixation of the first connecting pipe 14, ensures the connection is sealed, and prevents coolant leakage. The outer side of the second heat-conducting baffle 12 is provided with a second slot 18 that matches the second connecting pipe 15. Similarly, this provides space for the installation of the second connecting pipe 15, ensuring a secure and well-sealed installation. Both sides of the first heat-conducting baffle 11 and the second heat-conducting baffle 12 are provided with wavy turbulence patterns 13. These patterns disrupt the flow of the coolant, increasing the contact area and time between the coolant and the baffle, thereby improving heat dissipation efficiency. An external radiator 3 is provided on the outside of the cooling box 1. The external radiator 3 can further reduce the coolant temperature and enhance the overall heat dissipation capacity. Multiple heat dissipation fins 4 are fixedly connected to the top and bottom of the external radiator 3. These fins increase the contact area between the external radiator 3 and the air, accelerating heat dissipation into the surrounding air and enhancing the heat dissipation effect.

[0022] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment further proposes that the return end of the external radiator 3 is fixedly connected to a return pipe 5. The return pipe 5 serves to guide the coolant after it has been cooled by the external radiator 3 back to its original position. One end of the return pipe 5 passes through the cooling box 1, precisely delivering the coolant back into the cooling box 1. The other end of the return pipe 5 extends to the third cooling channel 10, allowing the coolant to smoothly enter the third cooling channel 10 and cool the relevant components within the channel. The input end of the external radiator 3 is fixedly connected to an output pipe 16. A flow valve is installed on the outside of the output pipe 16, and a temperature monitoring device is installed on the outside of the heat conduction plate 6. This allows the coolant flow rate to increase as the temperature increases, achieving adaptive cooling. Temperature control is implemented. The output pipe 16 is used to deliver the coolant in the cooling tank 1 to the external radiator 3. A liquid pump is installed on its outside, which provides power for the circulation of the coolant, driving the coolant to circulate throughout the cooling system. This ensures that the coolant can continuously flow from the cooling tank 1 to the external radiator 3 through the output pipe 16. One end of the output pipe 16 passes through the first cooling channel 8, allowing the coolant to exchange heat with surrounding heat-generating components within the first cooling channel 8, removing heat. An IGBT module 7 is installed on the outside of the heat-conducting plate 6. The heat-conducting plate 6 can quickly conduct away the heat generated by the IGBT module 7 during operation, preventing the IGBT module 7 from overheating and causing performance degradation or damage, thus improving its operational stability and reliability. A sealing plate 2 is installed on the outside of the cooling tank 1 to prevent coolant leakage, ensuring the airtightness of the cooling system and maintaining normal coolant circulation and cooling effect.

[0023] The working principle of this utility model is as follows: The heat-conducting plate 6 conducts heat to the IGBT module 7. The control pump directs the coolant to the first cooling channel 8 through the output pipe 16. After absorbing the heat of the IGBT module 7 along the longitudinal channel, the coolant flows into the second cooling channel 9 through the first connecting pipe 14. The water flow direction in the second cooling channel 9 is opposite to that in the first cooling channel 8 (reverse flow design). It exchanges heat with the first cooling channel 8 through the first heat-conducting baffle 11. After cooling down, it enters the third cooling channel 10 through the straight second connecting pipe 15. The laminar boundary layer is broken: the texture protrusion causes the water flow to periodically separate and reattach, transforming laminar flow into turbulent flow and increasing the effective heat transfer area. The coolant finally flows back to the external heat sink 3 through the return pipe 5. The setting of multiple heat dissipation fins 4 accelerates the cooling of the coolant.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
