It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0037] Refer to Figures 1 to 5 As shown, this embodiment provides a photovoltaic and energy storage integrated machine, including a box body 100, a partition plate 3, an air inlet assembly 4, an air outlet assembly 5, a first fan 6, a radiator 31 and a second fan 7.

[0038] Furthermore, the partition plate 3 is arranged in the box body 100. The partition plate 3 divides the space in the box body 100 into a first cavity 1 and a second cavity 2. The first cavity 1 and the second cavity 2 are arranged in the up and down direction. A first element is accommodated in the first cavity 1, and this first element is specifically a battery 11. A second element is accommodated in the second cavity 2, and this second element is specifically a power component 21. By separating the first cavity 1 and the second cavity 2 with the partition plate 3, the influence of the heat generated by the power component 21 on the battery 11 can be effectively reduced, and the service life of the battery can be improved. The battery in this embodiment refers to a plurality of storage batteries.

[0039] Even further, a first heat dissipation air duct 12 and a second heat dissipation air duct 13 are formed in the first cavity 1, and a third heat dissipation air duct 23 is formed in the second cavity 2.

The second ventilation opening 9 is used to communicate the second heat dissipation air duct 13 and the third heat dissipation air duct 23. The first ventilation opening 8 and the second ventilation opening 9 are located on the left and right sides of the radiator.

[0040] The air inlet assembly 4 includes a first air inlet 41 and a second air inlet 42, and both the first air inlet 41 and the second air inlet 42 are composed of a plurality of through holes. Further, the first air inlet 41 and the second air inlet 42 are provided at the bottom of the box body 100, and the first air inlet 41 and the second air inlet 42 are located on the left and right sides of the battery 11.

[0041] More specifically, the first air inlet 41 and the second air inlet 42 are symmetrically arranged on the left and right at the bottom of the box body 100, and the battery 11 does not block the first air inlet 41 and the second air inlet 42, ensuring that the low-temperature gas from the outside can smoothly enter the interior of the integrated energy storage and photovoltaic device.

The setting of the first fan 6 facilitates the low-temperature gas from the outside to directly take away the heat of the power component 21, greatly improving the heat dissipation efficiency.

[0042] The air outlet assembly 5 includes a fan cover 52, an air outlet 51 and a baffle 53. Refer to Figure 3 and Figure 4 As shown, the baffle 53 has a main body portion 531 and a warping portion 532. The main body portion 531 has a notch 10 that can communicate with the outside.

[0043] The air outlet 51 includes a plurality of grilles, and the grilles have a plurality of through holes 511. The setting of the fan cover 52 can, on the one hand, prevent rainwater from directly dripping onto the second fan 7 through the through holes 511, and on the other hand, can play a role in reducing wind noise. Specifically, the second fan 7 is installed on the fan cover 52. The fan cover 52 has an inclined slope 521, and the included angle between the inclined slope 521 and the horizontal plane is 45 - 60°, and more specifically, the included angle between the inclined slope 521 and the horizontal plane is 60 degrees; the baffle 53 is fixedly connected to the fan cover 52 by riveting or welding, and a sealant is applied between the two.

[0044] The air outlet 51 is provided on the upper right side of the second cavity 2, and the air outlet 51 is communicated with the third heat dissipation air duct 23. An air outlet channel is formed between the warping portion 532 and the grilles. The top of the grilles is slightly lower than the bottom of the main body portion 531, and the bottom of the inclined slope 521 is flush with the lower edge of at least one through hole 511 to ensure that the accumulated water can be smoothly discharged. The setting of the warping portion 532 is for waterproofing on the one hand and for discharging the high-temperature gas inside to the outside of the box body 100 on the other hand.

[0045] The first fan 6 and the radiator 31 are arranged on the partition plate 3, and the radiator 31 is used to absorb the heat dissipated by the power components 21. More specifically, the first fan 6 is arranged between the heat dissipation fins of the radiator 31 to dissipate the heat accumulated on the radiator 31. Combined with Figure 1 and Figure 5 As shown, the radiator 31 is provided with a mounting groove 311 for mounting the first fan 6, and the distance between the first fan 6 and the four side surfaces of the mounting groove 311 is 20-30 mm.

[0046] The integrated photovoltaic and energy storage machine further includes a carrier board 101 for carrying the battery 11, an upper cover 102 and a controller. A first cavity 1 is formed between the carrier board 101 and the partition plate 3, and a second cavity 2 is formed between the upper cover 102 and the partition plate 3.

[0047] The working principle of the integrated photovoltaic and energy storage machine in this embodiment is as follows:

[0048] During the use of the integrated photovoltaic and energy storage machine, the heat generated by the power components 21 mainly accumulates in the second cavity 2. When the internal temperature of the box body 100 reaches the critical value, the system controls the first fan 6 and the second fan 7 to start. The second fan 7 extracts the high-temperature gas in the second cavity 2 along the air outlet 51. At this time, the low-temperature gas from the outside enters through the first air inlet 41 and the second air inlet 42 and enters the inside of the box body 100 along the left and right sides of the battery 11. After a part of the low-temperature gas passes over the battery 11, it passes through the radiator 31 from left to right under the blowing of the first fan 6, taking away the heat accumulated on the radiator fins. Another part of the low-temperature gas directly passes over the power components and is finally extracted by the second fan 7 to the outside of the box body 100. Thus, the exchange of gas and heat inside and outside the integrated photovoltaic and energy storage machine is completed, avoiding overheating and burning of the power components and the battery.

[0049] The integrated photovoltaic and energy storage machine in this embodiment has at least the following advantages:

[0050] (1) The air duct design is more reasonable, avoiding the passage of cold air from local areas, and the heat dissipation effect is better;

[0051] (2) By arranging the first fan 6 inside the radiator 31, the cold air can directly take away the heat generated by the power components 21, greatly improving the heat dissipation efficiency and avoiding overheating and burning of the power components and the battery;

[0052] (3) By arranging the inclined slope 521 and the baffle 53 of the fan cover 52, while ensuring the waterproof reliability, the air outlet area is increased, effectively improving the heat dissipation efficiency.
