[0031] Furthermore, the hood assembly 201 includes a hood shell 201a disposed at the left and right ends of the converter body 102, an outer end of the hood shell 201a is provided with an air inlet 201b, an inner end of the hood shell 201a is provided with an air outlet 201c, a dust plate 201d is fixedly connected to the hood shell 201a, and a water outlet 201e is provided on the lower side of the hood shell 201a; the louver assembly 202 includes a plurality of first louvers 202a fixedly connected to the hood shell 201a, a plurality of second louvers 202b fixedly connected to the hood shell 201a, and a plurality of second louvers 202c fixedly connected to the hood shell 201a. The louver 202b is located on the outside of the dustproof plate 201d, and a plurality of third louvers 202c are provided on the inner side of the second louver 202b. The plurality of third louvers 202c are fixedly connected to the hood shell 201a, and reinforcing ribs 202d are installed in the vertical direction behind the first louver 202a and the second louver 202b; the plurality of first louvers 202a close to the air inlet 201b are tilted toward the air inlet 201b, and the plurality of first louvers 202a are arranged in an upper and lower array, and the spacing between the plurality of first louvers 202a does not exceed the vertical projection size of the first louver 202a.

[0032] Preferably, multiple second louvers 202b are installed on the inner side of the first louver 202a, and the multiple second louvers 202b are mirror-imaged with the first layer of louvers, the upper ends of the multiple second louvers 202b are closely attached to the upper ends of the first layer of louvers, the multiple third louvers 202c are horizontally spaced a certain distance from the second layer of louvers, the bottoms of the multiple third louvers 202c are inclined toward the air outlet 201c, the inclination angles of the first louver 202a and the second louver 202b are 74°, and the inclination angle of the third louver 202c is 61°.

[0033] It should be noted that the third louver 202c is installed after the second louver 202b, and is spaced a certain distance from the second louver 202b in the horizontal direction. The third louver 202c is installed at an angle, with the bottom inclined toward the air outlet 201c, and is fixed on the hood shell 201a on the left and right, and arranged in an upper and lower array, with a spacing not exceeding the vertical projection size of the third louver 202c. At least two reinforcing ribs 202d are installed in the vertical direction behind the first louver 202a and the second louver 202b. The reinforcing ribs 202d are used to fix the first layer of louvers and the second layer of louvers together in the array direction. The dustproof plate 201d is inserted from the bottom of the hood shell and fixed at the bottom of the hood shell. The dustproof plate 201d can be a filter screen or filter cotton; the filter screen can be made of a wire mesh plate, which has a high ventilation rate and is conducive to heat dissipation; the filter cotton has a large wind resistance, but a good dustproof effect.

[0034] Furthermore, the water retaining assembly 203 includes a funnel-shaped water retaining plate 203a installed at the air outlet 201c, a spacing is provided between the funnel-shaped water retaining plate 203a and the third louver 202c, a horizontal water retaining plate 203b fixedly connected to the air hood shell is provided at the top of the third louver 202c, the funnel-shaped water retaining plate 203a is installed on the side of the air outlet 201c, and behind the third louver 202c, the space between the funnel-shaped water retaining plate 203a and the third layer of louvers serves as the air outlet 201c, a horizontal water retaining plate 203b is provided on the top of the third louver 202c, the horizontal water retaining plate 203b is fixed on the air hood shell, and its height is lower than the upper end of the third layer of louvers, a drain outlet is provided at the bottom of the air hood shell, the drain outlet is close to the air inlet 201b, and is located at the bottom of the first louver 202a, the second louver 202b and the funnel-shaped water retaining plate 203a.

[0035] When the inclination angles of the first louver 202a and the second louver 202b are 74° and the inclination angle of the third louver 202c is 61°, the air volume of the air outlet 201c is the maximum.

[0036] The experimental data are as follows:

[0037]

[0038] It can be seen from the above table that when the angles of the first louver 202a and the second louver 202b are 75° and the third louver is 60°, the air intake volume reaches the maximum. In order to further measure at what angle the third louver 202c is at, the air intake volume is the maximum, the angles of the first louver 202a and the second louver 202b are set to 75°, and the angle of the third louver 202c is changed so that the angle of the third louver 202c varies around 60°. The experimental data are measured as follows:

[0039]

[0040] It can be seen that when the angles of the first louver 202a and the second louver 202b are 75° and the angle of the third louver 202c is 61°, the air volume at the air outlet 201c is the largest. Then, as the angle of the third louver 202c increases, the air volume decreases. In order to further measure the maximum air volume, the angle of the third louver 202c is set to 61°, and the angles of the first louver 202a and the second louver 202b are changed around 75°. The experimental data are measured as follows:

[0041]

[0042] It can be seen from the above table that when the angles of the first louver 202a and the second louver 202b are 74° and the angle of the third louver 202c is 61°, the air volume at the air outlet 201c is the largest.

[0043] The first louver 202a is inclination direction from the bottom to the air inlet 201b side through the folded edges on both sides, and the inclination angle is adjustable, which divides the air duct into two sections. Through the obstruction of the first louver 202a, water droplets with a smaller initial velocity from top to bottom can be completely blocked, and the water droplets cannot enter the inner end. The second louver 202b is inclination direction opposite to the first louver 202a, and the inclination angle is symmetrical with the first louver 202a. When the initial velocity of the water droplets is very fast and it hits the first louver 202a from the horizontal direction and breaks through the first louver 202a, it will be blocked by the second louver 202b, and the water droplets will be guided downward. The third louver 202c is inclination direction from the bottom to the air inlet 201b side through the folded edges on both sides. The blade 202c is inclined in the same direction as the first louver 202a, and the inclination angle is adjustable. Together with the second louver 202b, the blade 202c divides the air duct into the second section and the third section. When the water droplets with a high initial velocity in the horizontal direction are blocked by the second louver 202b and diverted downward, under the action of the strong suction force of the fan, some small water droplets still overcome their own gravity and continue to splash upward with the airflow. These small water droplets will be blocked by the third louver 202c and continue to be diverted downward, forming a funnel-shaped baffle. As the last protective structure, the water plate 203a is fixed on the wind hood shell 201a by folding three sides. Except for the top air outlet 201c, the other three sides are sealed. The slope of the funnel-shaped water baffle 203a is adjustable. The water droplets blocked and diverted downward by the second louver 202b and the third louver 202c will eventually converge on the funnel-shaped water baffle 203a, and will be diverted to the drain outlet at the bottom through the slope of the funnel-shaped water baffle 203a and flow out of the outside of the wind hood.

[0044] Example 2, reference Figure 1 to Figure 9 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a circulating heat dissipation component 300 of a grid-type outdoor energy storage inverter heat dissipation protection system, which solves the problem of how to better achieve heat dissipation. It includes a first fan assembly 301 including a first external circulation heat dissipation air duct 301a arranged on the inverter body 102, and a module radiator air cavity 301b is provided on the external circulation heat dissipation air duct, and a reactor air cavity 301c is provided at the lower end of the module radiator air cavity 301b; the second fan assembly 302 includes a second external circulation heat dissipation air duct 302a arranged on the inverter body 102, a heat exchange fan air cavity 302b is provided on the second external circulation heat dissipation air duct 302a, and a two-phase flow heat exchanger external circulation air cavity 302c is provided at the lower end of the heat exchange fan air cavity 302b.

[0045] Specifically, the first external circulation heat dissipation air duct 301a, the module fan air cavity, the module radiator air cavity 301b, and the reactor air cavity 301c are connected in sequence from top to bottom.

[0046] Furthermore, the sealing assembly 303 includes a semicircular sealing strip 303a arranged on the butt joint surface between the module radiator air cavity 301b, a limit block 303b is provided on the sealing strip, a water retaining groove 303c is provided on the back of the butt joint surface between the module fan air cavity and the module radiator air cavity 301b, a drainage pipe 303d is provided at the bottom of the water retaining groove 303c, and a side bubble sealing strip 303e is provided between the heat exchanger air cavity and the two-phase flow heat exchanger external circulation air cavity 302c, which is used to block the semicircular sealing strip 303a from the module in case of failure. The water splashed out of the fan air cavity is used to protect important charged parts; the internal circulation heat dissipation component 304 includes an internal circulation heat dissipation closed cabin 304a arranged on the inverter body 102, and the internal circulation heat dissipation closed cabin 304a is provided with a two-phase flow heat exchanger internal circulation air cavity 304b, and a spoiler fan 304c is provided on the right side of the heat exchange fan air cavity 302b. The bottom of the inverter body 102 is provided with core components 304d, and the core components 304d here refer to the control elements and switch elements in the inverter body 102.

[0047] It should be noted that air enters from the top of the module fan air cavity, and semicircular sealing strips 303a are used to seal between the sheet metal veneers of the module fan air cavity, between the module radiator air cavity 301b and the module fan air cavity, and between the reactor air cavity 301c and the module radiator air cavity 301b, and limit blocks 303b are provided to control the sealing strips to be within a reasonable compression range. The inner circulation air cavity 304b of the two-phase flow heat exchanger absorbs air at the bottom and discharges air at the top. The power devices, switches and other core devices of the converter body 102 are dispersed in the inner circulation heat dissipation closed cabin 304a. A spoiler fan 304c is arranged in the upper part of the inner circulation heat dissipation closed cabin 304a to accelerate the air circulation flow in the cabin.

[0048] When in use, heat is dissipated to the outside through the internal circulation air cavity 304b of the two-phase flow heat exchanger, and a turbulent fan 304c is arranged inside to accelerate air flow and heat transfer of core components 304d. The internal circulation heat dissipation closed cabin 304a is not in direct contact with the outside air, which can effectively prevent external water, dust and salt fog from affecting the performance of the internal core components 304d. An internal and external double circulation heat dissipation and compartment protection scheme are adopted. The internal and external double circulation heat dissipation refers to completely isolating the core components 304d in the cabinet from the external heat dissipation air duct. The external circulation heat dissipation is divided into two air ducts, and the heat is brought out of the cabinet through the interaction between the external circulation fan and the external air. The external circulation air duct mainly dissipates heat to the heat sink of the power device with large heat generation; the switch core device in the cabinet has a small heat generation, and the heat is dissipated to the outside through the internal circulation air cavity 304b of the two-phase flow heat exchanger, and is not in direct contact with the outside air. The heat is circulated by the internal turbulent fan 304c. Two external circulation air ducts are listed, but not limited to two, and can be adjusted according to actual needs.
