[0032] Example 1

[0033] like Figures 1-7 As shown, this embodiment provides a high-voltage box with liquid cooling and dehumidification function, which includes: a high-voltage box body 100, the high-voltage box body 100 including a high-voltage box main body 200 and a dehumidification and heat dissipation part 300 disposed on one side of the outer wall of the high-voltage box main body 200; the high-voltage box main body 200 is provided with an installation cavity 210 for installing electronic components inside, and the high-voltage box main body 200 is provided with an installation port 220 communicating with the installation cavity 210 on the outer wall of the side of the high-voltage box main body 200 near the dehumidification and heat dissipation part 300; the dehumidification and heat dissipation part 300 includes a heat sink assembly 310 disposed at the installation port 220 and a dehumidification and heat dissipation air duct assembly 320 for blowing external air to the heat sink assembly (310); the dehumidification and heat dissipation air duct assembly 320 covers the heat sink assembly 310.

[0034] The dehumidification and heat dissipation unit 300 in this embodiment integrates heat dissipation and dehumidification functions, reducing the need for external equipment and improving space utilization.

[0035] In this embodiment, the radiator assembly 310 dissipates heat through heat conduction and convection, thereby improving heat dissipation efficiency. The dehumidifying and heat dissipation duct assembly 320 guides external airflow through the radiator assembly 310 to achieve dehumidification while enhancing heat dissipation.

[0036] In this embodiment, the heat sink assembly 310 includes a high-pressure tank heat sink 311 arranged at the mounting port 220, and a high-pressure tank liquid cooling plate 312 fixedly connected with the high-pressure tank heat sink 311. The high-pressure tank heat sink 311 is provided with first heat dissipation teeth 313 extending into the mounting cavity 210, and the high-pressure tank liquid cooling plate 312 is provided with second heat dissipation teeth 314 facing the outside of the high-pressure tank body 200.

[0037] By the way of combining the high-pressure tank heat sink 311 and the high-pressure tank liquid cooling plate 312 in this embodiment, double heat dissipation is achieved. The first heat dissipation teeth 313 extend into the inside of the mounting cavity 210 to directly absorb the heat generated by the electronic components, and the second heat dissipation teeth 314 face the outside of the high-pressure tank to facilitate heat exchange with the external air, thereby enhancing the heat dissipation effect. In addition, when condensation occurs, the condensation will appear on the second heat dissipation teeth 314 and will fall due to the effect of gravity, thereby reducing the humidity.

[0038] In this embodiment, the side of the first heat dissipation teeth 313 away from the high-pressure tank liquid cooling plate 312 is provided with an internal heat dissipation fan 230 for blowing out the heat in the mounting cavity 210.

[0039] By the arrangement of the internal heat dissipation fan 230 in this embodiment, the air in the mounting cavity 210 can be blown onto the first heat dissipation teeth 313 of the high-pressure tank heat sink 311. Since the high-pressure tank liquid cooling plate 312 is in close contact with the high-pressure tank heat sink 311, when the internal temperature of the high-pressure tank is higher than the temperature of the high-pressure tank liquid cooling plate 312, the high-pressure tank liquid cooling plate 312 can continuously cool the inside of the high-pressure tank.

[0040] In this embodiment, the high-pressure tank liquid cooling plate 312 is fixedly connected with a high-pressure tank liquid cooling pipe 315 arranged along the length direction of the high-pressure tank body 200. The side of the high-pressure tank liquid cooling pipe 315 away from the high-pressure tank liquid cooling plate 312 is connected with an external cooling loop.

[0041] By the arrangement of the high-pressure tank liquid cooling pipe 315 in this embodiment, the cooling liquid is ensured to circulate in the high-pressure tank liquid cooling plate 312 to achieve continuous heat dissipation. The external cooling loop can provide low-temperature cooling liquid to maintain the heat dissipation capacity of the high-pressure tank liquid cooling plate 312.

[0042] In this embodiment, the dehumidification and heat dissipation air duct assembly 320 includes a dehumidification air cover 321 fixedly connected with the side outer wall of the high-pressure tank body 200. The end of the dehumidification air cover 321 away from the high-pressure tank liquid cooling pipe 315 is provided with a dehumidification circulating fan 322, and the end of the dehumidification air cover 321 close to the high-pressure tank liquid cooling pipe 315 is provided with an air outlet 323 for blowing out the air blown by the dehumidification circulating fan 322. The dehumidification air cover 321 and the side of the high-pressure tank body 200 form an air duct for the air blown by the dehumidification circulating fan 322 to blow to the side of the air outlet 323.

[0043] The dehumidification air cover 321 in the embodiment forms an air duct on one side of the high-voltage box body 200 with the high-voltage box body 200, which is used for the dehumidification circulating fan 322 to blow air to the air outlet 323 side, guides the external air to flow through the high-voltage box liquid cooling plate 312, and realizes the dehumidification function; the dehumidification circulating fan 322 provides power to accelerate the flow of external air and improve the dehumidification efficiency; the air outlet 323 discharges air to keep the air in the air duct circulating, realizes the high-efficiency dehumidification effect, reduces the humidity in the high-voltage box, and effectively prevents the occurrence of condensation.

[0044] In the embodiment, the dehumidification and heat dissipation air duct assembly 320 further comprises an air heater 324 arranged at a position close to the dehumidification circulating fan 322 on the outer wall of one side of the high-voltage box body 200, and the air heater 324 is located between the dehumidification circulating fan 322 and the high-voltage box liquid cooling plate 312.

[0045] Through the arrangement of the air heater 324 in the embodiment, the air blown by the dehumidification circulating fan 322 can be heated, and then when the heated air contacts the high-voltage box liquid cooling plate 312, the residual condensation on the second heat dissipation teeth 341 can be blown dry, effectively improving the dehumidification effect and increasing the dehumidification efficiency.

[0046] In the embodiment, one side of the mounting cavity 210 is provided with an opening 240 communicating with the mounting cavity 210, and the high-voltage box upper cover 250 for closing the mounting cavity 210 is arranged at the opening 240.

[0047] Through the arrangement of the high-voltage box upper cover 250 in the embodiment, the mounting cavity 210 is closed to protect the internal electronic components from the external environment, prevent dust, moisture and the like from entering the inside of the mounting cavity 210, and facilitate opening of the mounting cavity 210 for maintenance and repair.

[0048] In the embodiment, the dehumidification air cover 321 is arranged in parallel with the high-voltage box upper cover 250 at the top, and the dehumidification air cover 321 is arranged in an inclined manner at the bottom, and the inclination direction is along the direction close to the high-voltage box liquid cooling pipeline 315.

[0049] Through the inclined arrangement of the dehumidification air cover 321 in the embodiment, the condensate water can be collected, the damage of water accumulation to the system is prevented, the need for manual intervention is reduced, and the maintenance cost is reduced.

[0050] In the embodiment, the dehumidification air cover 321 is arranged in parallel with the high-voltage box upper cover 250 at the top, and the dehumidification air cover 321 is arranged in an inclined manner at the bottom, and the inclination direction is along the direction close to the high-voltage box liquid cooling pipeline 315.

[0051] Through the arrangement of the drain port 3211 in the embodiment, when condensation occurs on the heat dissipation teeth of the high-voltage box liquid cooling plate 312, the condensate water will gradually increase and drop on the dehumidification air cover 321 due to gravity, and the bottom of the dehumidification air cover 321 is an inclined surface, which can collect the condensate water and discharge it through the drain port 3211 at the bottom of the dehumidification air cover 321 to realize the dehumidification function.

[0052] The high-voltage box with liquid cooling heat dissipation and dehumidification function in the embodiment can blow the air in the high-voltage box to the high-voltage box radiator 311 when the electronic components in the high-voltage box generate heat, and the high-voltage box liquid cooling plate 312 is in close contact with the high-voltage box radiator 311. When the temperature in the high-voltage box is higher than the temperature of the high-voltage box liquid cooling plate 312, the high-voltage box liquid cooling plate 312 is connected with the external cooling circuit, so that the low-temperature cooling liquid passes through the inside of the high-voltage box liquid cooling plate 312, and the high-voltage box liquid cooling plate 312 has the function of continuous cooling. The dehumidification air cover 321 and the high-voltage box body cover the high-voltage box radiator 311, the high-voltage box liquid cooling plate 312, the air heater 324, and the dehumidification circulating fan 322 to form an air duct. The dehumidification circulating fan 322 blows the air in the energy storage cabinet to the air heater 324 and the high-voltage box liquid cooling plate 312 in sequence. If the temperature of the air outside the high-voltage box body 100 is higher than the temperature of the high-voltage box liquid cooling plate 312, and the relative air humidity meets the condensation condition, condensation will occur on the high-voltage box liquid cooling plate 312, and the condensed water will gradually increase and drop to the dehumidification air cover 321 due to gravity. The bottom of the dehumidification air cover 321 is inclined, so that the condensed water can be collected and discharged through the drain port 3211 at the bottom of the dehumidification air cover 321 to realize the dehumidification function. Because the condensation phenomenon mainly depends on the relative air humidity and the temperature difference. When the temperature difference between the air outside the high-voltage box and the high-voltage box liquid cooling plate 312 is relatively large, and the relative air humidity is high, the air heater 324 does not need to work, and only the dehumidification circulating fan 322 and the high-voltage box liquid cooling plate 312 need to work to realize the dehumidification function. When the temperature difference between the air outside the high-voltage box and the high-voltage box liquid cooling plate 312 is not very large, and the relative air humidity outside the high-voltage box is high, the air heater 324 works, heats the air blown by the dehumidification circulating fan 322, and then the heated air contacts the high-voltage box liquid cooling plate 312 to effectively improve the dehumidification effect and increase the dehumidification efficiency.

[0053] It is easy to understand that, based on one or more embodiments provided in the present application, other embodiments can be obtained by combining, splitting, recombining, etc. of the embodiments of the present application, and these embodiments do not exceed the protection scope of the present application.

[0054] In summary, the above is only a preferred embodiment of the present application, and any changes and modifications made within the scope of the present application shall be included in the scope of the present application.
