[0044] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0045] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0046] Combine Figure 1 、 Figure 2 and Figure 3 As shown, an embodiment of the present disclosure provides an energy storage cabinet battery rack, which includes a battery rack body 1, a plurality of support beams 2 and a plurality of placement structures 4; the plurality of support beams 2 are fixedly arranged in the battery rack body 1 at intervals in the height direction; the plurality of placement structures 4 are arranged between two adjacent support beams 2 on the same horizontal plane; the placement structure 4 includes a support frame 401, a limit frame 402 and a plurality of heat sinks 405; the support frame 401 is fixedly arranged between two adjacent support beams 2 on the same horizontal plane; the limit frame 402 is fixedly arranged on the top side of the support frame 401; and the plurality of heat sinks 405 are uniformly fixedly arranged on the bottom side of the support frame 401 at equal distances.

[0047] The support frame 401 and the limiting frame 402 together form a placement portion for placing the energy storage battery; the heat sink 405 has a heat dissipation area, and the heat dissipation area can at least be connected to the bottom of the placement portion.

[0048] The energy storage cabinet battery rack provided by the embodiment of the present disclosure is provided with a support beam 2, a support frame 401, a limit frame 402 and a heat sink 405. The support frame 401 and the limit frame 402 together form a placement portion for placing energy storage batteries. After the batteries are placed in the placement portion, the bottom of the batteries are not blocked, thereby effectively and efficiently dissipating heat from the bottom area of ​​the stacked batteries. In addition, a plurality of heat sinks 405 are uniformly and equidistantly fixed to the bottom side of the support frame 401. The heat dissipation area of ​​the heat sink 405 can be at least conductively connected to the bottom of the placement portion, thereby solving the problem of complete contact between the battery rack and the battery, greatly improving the heat dissipation effect of the heat at the bottom of the battery, and solving the problem of high temperature easily generated at the bottom of the energy storage battery.

[0049] In summary, the energy storage cabinet battery rack provided by the embodiment of the present disclosure has the beneficial effect of good heat dissipation effect on the bottom of the battery and can effectively solve the problem of high temperature easily generated at the bottom of the energy storage battery.

[0050] In one embodiment, the heat sink 405 includes a first heat dissipation plate body and a second heat dissipation plate body; and the first heat dissipation plate body and the second heat dissipation plate body are connected in a V shape to form a heat dissipation area in a V-shaped groove state; and the opening surface of the heat dissipation area is at least partially connected to the bottom of the placement portion.

[0051] Specific, combined Figure 6 To further explain in detail, the heat sink 405 is specifically configured as a first heat sink body and a second heat sink body connected to each other in a V-shape. The V-shaped heat sink 405 has a larger contact area when wind passes through, and the opening surface of the V-shaped heat dissipation area is connected to the bottom of the placement portion, so that the heat dissipation airflow can take away more heat and further improve the cooling effect on the bottom of the energy storage battery.

[0052] In one embodiment, a radiator body 3 is fixed to a side end of the battery rack body 1 ; the air-blowing side of the radiator body 3 corresponds to the V-groove end 4051 of the heat sink 405 .

[0053] Specific, combined Figure 1 and Figure 6 To further detail, a radiator body 3 is fixed to the side of the battery rack body 1. This radiator body 3 has a built-in fan, and can be used by technicians skilled in the art based on actual circumstances. The air-blowing side of the radiator body 3 corresponds to the V-grooved end 4051 of the heat sink 405. This allows the radiator body 3 to blow and draw air from the V-grooved ends 4051 at both ends of the heat sink 405, significantly increasing the flow rate of air within the V-shaped heat dissipation area. This allows the heat sink 405 to more efficiently cool and dissipate heat from the bottom of the energy storage battery.

[0054] In one embodiment, V-shaped groove ends 4051 are formed at both ends of the heat sink 405 , and a blower fan 4052 is further disposed in the V-shaped groove ends 4051 .

[0055] Specific, combined Figure 7 To further explain in detail, blowers 4052 are respectively provided in the V-groove ends 4051 at both ends of the heat sink 405. In this way, even if the above-mentioned radiator body 3 is not provided on the side end of the battery rack body 1, the blowers 4052 at both ends of the V-groove end 4051 can respectively blow and suck airflow, thereby significantly improving the flow rate of the gas inside the V-shaped heat dissipation area, and enabling the heat sink 405 to cool and dissipate heat more efficiently at the bottom of the energy storage battery.

[0056] In one embodiment, heat dissipation fins 4053 are respectively provided on the outside of the first heat dissipation plate body and the second heat dissipation plate body; and the heat dissipation fins 4053 are respectively spirally wrapped around the outer periphery of the first heat dissipation plate body and the second heat dissipation plate body.

[0057] Specific, combined Figure 8 To further explain in detail, heat dissipation fins 4053 are spirally wrapped around the outside of the first heat dissipation plate body and the second heat dissipation plate body, and the heat dissipation fins 4053 can be arranged to be connected end to end in a conductive loop. In this way, when high temperature is generated in the V-shaped heat dissipation area of ​​the heat dissipation fins 405, there is a temperature difference between the inside and outside of the first heat dissipation plate body and the second heat dissipation plate body. The temperature difference can cause the heat dissipation liquid in the heat dissipation fins 4053 to circulate to a certain extent, thereby realizing the function of conducting the heat in and out of the V-shaped heat dissipation area, and also enabling the heat dissipation fins 405 to cool and dissipate heat from the bottom of the energy storage battery more efficiently.

[0058] In one embodiment, a square support bar 404 is fixedly provided at the inner end of the top side of the support frame 401 ; wherein the cross section of the square support bar 404 is arc-shaped, and the arched end of the square support bar 404 faces upward.

[0059] Specific, combined Figure 3 To further explain in detail, a square support bar 404 is provided, and the curved sides of the square support bar 404 can respectively contact the bottom of the energy storage battery. While the contact area with the bottom of the energy storage battery is small, a heat dissipation gap can also be formed to better utilize the heat dissipation from the bottom of the energy storage battery.

[0060] In one embodiment, the insulating frame 403 is sleeved on the limiting frame 402 ; wherein a slot 4031 provided on the bottom side of the insulating frame 403 is inserted and matched with the limiting frame 402 .

[0061] Specific, combined Figure 3 To further explain in detail, the insulating frame 403 can be made of insulating rubber to support the battery shell and keep the energy storage battery in a stable position.

[0062] Working principle: When using the device of the present invention to place the battery, insert the bottom of the battery into the insulating frame 403 accordingly, and insert the bottom of the battery along the curved surface 4032 on the inner side of the top of the insulating frame 403 until the bottom of the battery is fully inserted. The bottom of the battery contacts the curved side of the square support bar 404 and is supported. The radiator body 3 generates wind blowing outward, and the V-shaped heat sink 405 has a larger contact area when the wind passes through, which can take away more heat.

[0063] In one embodiment, the inner side of the top end of the insulating frame 403 is configured as an arc-shaped surface 4032 .

[0064] Specific, combined Figure 4 To further explain in detail, the inner side of the top of the insulating frame 403 is set to an arc-shaped surface 4032. On the one hand, the top opening of the insulating frame 403 can be larger, which is more conducive to the installation of energy storage batteries. The arc-shaped surface 4032 on the inner side of the top of the insulating frame 403 can also avoid bumps and scratches on the energy storage batteries.

[0065] In one embodiment, a plurality of heat dissipation grooves 4033 are spaced apart along the circumference of the insulating frame 403 ; the heat dissipation grooves 4033 include a first groove body extending along the height direction and located on the inner wall of the insulating frame 403 .

[0066] Specific, combined Figure 5 To further explain in detail, a plurality of heat dissipation grooves 4033 are arranged at intervals along the circumference of the insulating frame 403, and a single heat dissipation groove 4033 is arranged to extend along the height direction of the insulating frame 403, and the first groove body in the heat dissipation groove 4033 is located on the inner frame wall of the insulating frame 403. In this way, when the energy storage battery is placed in the insulating frame 403, the first groove body in the heat dissipation groove 4033 can form a heat dissipation gap groove with the energy storage battery, thereby facilitating the heat dissipation of the side of the energy storage battery through the heat dissipation gap groove, thereby further improving the heat dissipation effect on the energy storage battery.

[0067] In one embodiment, the heat dissipation groove 4033 further includes a second groove body located on the top side wall of the insulation frame 403 , and the second groove body is smoothly connected to the first groove body in the arc surface 4032 .

[0068] Specific, combined Figure 5 Further detailed description, the heat dissipation groove 4033 has a second groove body on the top side frame wall of the insulating frame 403, and the second groove body and the first groove body are smoothly transitioned and connected in the arc surface 4032, so that the heat dissipation gap groove formed by the first groove body can be guided and extended to a certain extent through the second groove body, so that the heat in the first groove body can be further dissipated into the external environment through the second groove body.

[0069] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. Throughout the present disclosure, "plurality" means two or more, unless otherwise specifically defined.

[0070] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
