[0022] The inlet flow channel 14 is composed of a first flow channel 6, a second flow channel 7, and a third flow channel 8. The ends of the first flow channel 6, the second flow channel 7, and the third flow channel 8 are all connected to a curved flow channel 13. The end of the curved flow channel 13 is fixedly connected to a confluence channel 9. The confluence channel 9 is connected to the outlet flow channel 10.

[0023] Multiple groups of dividing protrusions 12 are arranged inside the inlet flow channel 14 , the confluence channel 9 and the outlet flow channel 10 , and the first flow channel 6 , the second flow channel 7 , the third flow channel 8 and the outlet flow channel 10 are divided into multiple thin flow channels by the multiple groups of dividing protrusions 12 .

[0024] In this embodiment, the mounting member 3 on one side of the flat plate 2 is connected to the battery. When the battery generates heat, ethylene glycol solution is introduced into the inlet 4 on one side of the flat plate 2. The solution first passes through the first flow channel 6, the second flow channel 7, and the third flow channel 8 in the inlet flow channel 14. The solution first passes through a plurality of thin flow channels separated by the dividing protrusion 12, and then passes through the curved flow channel 13 and converges into the converging flow channel 9. The converging flow channel 9 contacts the dividing protrusion 12 to extend the flow time. After converging, the flow channels are formed as a whole through the outlet flow channel 10 to absorb and discharge the heat generated by the battery, increase the flow channel area as a whole, and improve the internal solution flow, thereby improving the heat exchange efficiency, reducing the temperature difference of the battery, and keeping the temperature of the equipment within a safe range.

[0025] As an implementation method, Figure 1 and Figure 3 As shown, a plurality of notches 11 are provided on one side of the confluence channel 9, and the notches 11 are arranged in an arc shape.

[0026] In this embodiment, by providing the arc-shaped notch 11 , after the solution converges to the inside of the confluence channel 9 , the internal fluid velocity is increased after the impact between the solution and the notch 11 .

[0027] As an implementation method, Figure 1 and Figure 3 As shown, the curved channel 13 is arranged in an S-shaped structure, and a separation protrusion 12 is arranged in the end of the curved channel 13 .

[0028] The curved flow channel 13 and the confluence channel 9 are arranged perpendicular to each other, and the curved flow channel 13 and the outlet flow channel 10 are arranged on the same side of the confluence channel 9 .

[0029] In this embodiment, an S-shaped bend channel 13 is utilized to increase the flow path of the solution from the fluids in the first channel 6, the second channel 7, and the third channel 8. At the same time, in cooperation with the separation protrusion 12, the end of the bend channel 13 is divided into thin channels to evenly dissipate heat and increase the convective heat transfer effect.

[0030] As an implementation method, Figure 1 and Figure 3 As shown, the first flow channel 6, the second flow channel 7, the third flow channel 8 and the outlet flow channel 10 are arranged parallel to each other.

[0031] The interiors of the inlet flow channel 14 and the outlet flow channel 10 are both configured to be curved.

[0032] In this embodiment, the curved inlet channel 14 and outlet channel 10 are used to improve the solution flow path and reduce the channel impact of the solution inside the channel. The entire channel is completed through the inlet channel 14, the curved channel 13, the confluence channel 9 and the outlet channel 10.

[0033] Working principle: When in use, the mounting piece 3 on one side of the flat plate 2 is connected to the battery. When the battery generates heat, ethylene glycol solution is introduced into the inlet 45 on one side of the flat plate 2. The solution first passes through the first flow channel 6, the second flow channel 7, and the third flow channel 8 in the inlet flow channel 14. The solution first passes through a plurality of thin flow channels separated by the dividing protrusion 12, and then passes through the curved flow channel 13 and converges into the confluence channel 9. The confluence channel 9 contacts the dividing protrusion 12 to extend the flow time. At the same time, after the impact of the solution and the recess 11 in the confluence channel 9, the internal fluid velocity is increased. After converging, it passes through the outlet flow channel 10 to form an overall flow channel, absorbs and discharges the heat generated by the battery, increases the flow channel area as a whole, and improves the internal solution flow, thereby improving the heat exchange efficiency, reducing the temperature difference of the battery, and keeping the temperature of the equipment running within a safe range.
