[0025] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail by combining with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0026] Referring to Figures 1-4 The high-power energy storage converter module heat dissipation structure 100 provided by the utility model, the high-power energy storage converter module heat dissipation structure 100 includes a first box 10, an internal circulation heat dissipation assembly arranged in the first box 10 and an external circulation heat dissipation assembly arranged at the bottom of the first box 10. The high-power energy storage converter module heat dissipation structure 100 further includes a second box 20, and the second box 20 is provided with an external circulation air inlet 21 and an external circulation air outlet 22 for connecting the external circulation heat dissipation assembly with the external environment. The internal circulation heat dissipation assembly blows out the heat outside the first box 10, and the external circulation heat dissipation assembly blows out the heat outside the second box 20 through the external circulation air outlet 22. The high-power energy storage converter module heat dissipation structure 100 provided by the utility model can realize the operation of discharging the heat generated by the components in the first box 10 into the external circulation heat dissipation assembly and discharging the heat outside the second box 20 through the external circulation air outlet 22 on the second box 20 by the external circulation heat dissipation assembly, so as to realize the operation of discharging the heat generated by the components outside the first box 10 under the condition of meeting the requirement of IP66 protection, and further meet the requirement of heat dissipation under the condition of high protection and sealing.

[0027] As Figure 1 and Figure 3As shown, in the embodiment provided by this utility model, a power board 11 is provided on one side of the first housing 10, and components are provided on the power board 11. The internal circulation heat dissipation assembly includes a first internal circulation fan 30 disposed on the power board 11 and an air duct baffle 31 disposed above the power board 11. The internal circulation heat dissipation assembly also includes a second internal circulation fan 33 disposed on the other side of the first housing 10 and an internal circulation radiator 32 for connecting the internal circulation heat dissipation assembly and the external circulation heat dissipation assembly. The first internal circulation fan 30 cools down the components on the power board 11 that generate heat due to the interference of the air duct baffle 31, thus controlling the temperature rise at that location. At the same time, it blows the heat to the opposite side inside the first housing 10, and then blows the heat generated by the components into the second internal circulation fan 33. The second internal circulation fan 33 blows the heat into the internal circulation radiator 32, and after entering the internal circulation radiator 32, the heat is blown out of the external circulation outlet 22 of the second housing 20 through the external circulation radiator inside the second housing 20.

[0028] like Figure 1 and Figure 3 As shown, in the embodiment provided by this utility model, the radiator outlet 322 of the internal circulation radiator 32 is located at the location of the second internal circulation fan 33, and the radiator inlet 321 of the internal circulation radiator 32 is disposed opposite to it on the other side inside the first housing 10. The second internal circulation fan 33 blows heat into the internal circulation radiator 32, so that the heat enters the internal circulation radiator 32 through the radiator inlet 321 disposed opposite to it on the other side inside the first housing 10. In addition, the internal circulation heat dissipation assembly also includes a third internal circulation fan 34 disposed at the radiator outlet 322 and an air duct cover 35 covering the third internal circulation fan 34. The air duct cover 35 at the air inlet of the internal circulation radiator 32 forms a sealed chamber through structural design. By installing the third internal circulation fan 34 inside the air duct cover 35 at the air inlet of the internal circulation radiator 32, and using the third internal circulation fan 34 to blow air towards the air inlet 321 of the radiator, since the entire cavity of the internal circulation radiator 32 from the air inlet 321 to the air outlet 322 of the radiator is sealed, a negative pressure is formed at the air outlet 322 of the radiator. The third internal circulation fan 34 blows the air inside the air duct cover 35 out of the air duct cover 35, so that the heat entering the internal circulation radiator 32 from the air inlet 321 flows to the air outlet 322 of the radiator under the action of negative pressure.

[0029] like Figure 4As shown, the internal circulation radiator 32 provided by this utility model also includes a plurality of harmonica tubes 323 disposed between the radiator air inlet 321 and the radiator air outlet 322, and a plurality of fins 324 disposed within the harmonica tubes 323. The second internal circulation fan 33 blows hot air around the radiator air inlet 321 into the harmonica tubes 323 of the internal circulation radiator 32. The heat contacts the wall of the aluminum profile harmonica tube 323 and is transferred to the outer surface of the harmonica tube 323 and the fins 324 in contact with the outer surface of the harmonica tube 323 through radiation, thereby completing the internal circulation heat dissipation operation. The external circulation air inlet 21 on the second housing 20 connects the harmonica tube 323 and fins 324 of the internal circulation radiator 32 with the external environment, thereby achieving the effect of blowing the heat on the harmonica tube 323 and fins 324 of the internal circulation radiator 32 out of the external circulation air outlet 22 of the second housing 20 through the external circulation radiator inside the second housing 20, thus meeting the heat dissipation requirements under a highly protected and sealed state.

[0030] like Figure 2 and Figure 4 As shown, in the embodiment provided by this utility model, the external circulation heat dissipation assembly includes a main power heat sink 41, an inverter inductor 42, and an external circulation fan 40 disposed at the bottom of the first housing 10. The bottom of the second housing 20 also has an external circulation air duct cover 23. The second housing 20 is installed at the bottom of the first housing 10 to enclose the external circulation heat dissipation assembly inside the second housing 20. Under the action of the internal circulation heat dissipation component, the heat of the components in the first housing 10 is transferred to the outer wall of the harmonica tube 323 and the fins 324 of the internal circulation heat sink 32. At this time, the external circulation fan 40 blows air towards the main power heat sink 41 and the inverter inductor 42. Meanwhile, the cold air in the external environment enters the second housing 20 through the external circulation air inlet 21 and flows through the outer wall of the harmonica tube 323 and the fins 324 of the internal circulation heat sink 32. This causes the heat on the outer wall of the harmonica tube 323 and the fins 324 of the internal circulation heat sink 32 to flow to the main power heat sink 41 and the inverter inductor 42 through radiation and air convection. The external circulation fan 40 blows air towards the main power heat sink 41 and the inverter inductor 42, so that the heat on the main power heat sink 41 and the inverter inductor 42 will flow out from the external circulation air outlet 22 of the second housing 20 through air convection, thereby achieving the heat dissipation effect.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
