[0042] As described in the background, energy storage containers, as integrated energy storage systems, enable efficient energy storage and release, making them suitable for a variety of applications. However, the batteries in these systems generate significant heat during charging and discharging. To extend battery life and improve system stability, energy storage containers typically require dedicated air conditioners to regulate battery temperature.

[0043] To meet the installation requirements of energy storage containers and other application scenarios, the installation space for various components inside the air conditioner, such as the electrical control box and condenser, is limited. On the one hand, this places high demands on the structural layout inside the air conditioner. On the other hand, it may cause some components to not function fully. For example, the electrical control box cannot fully dissipate heat, affecting the stability of the air conditioner. Another example is that the contact area between the condenser and the air is small, affecting the cooling energy efficiency of the air conditioner.

[0044] In order to solve the problems of poor heat dissipation and low refrigeration efficiency of existing air conditioners due to limited installation space, the present application provides an air conditioner, including a shell, a first electric control box and a second electric control box, the first electric control box and the second electric control box are both arranged in the shell, and the second electric control box is arranged on the side of the shell, wherein a driver is arranged in the first electric control box, and a control panel is arranged in the second electric control box.

[0045] When the above technical solution is adopted, dividing the electrical control box into two parts can provide a larger space for the arrangement of the condenser, thereby increasing the contact area between the condenser and the air, which is beneficial to improving the cooling energy efficiency of the air conditioner.

[0046] Refer to the following Figure 1 and Figure 5 , the air conditioner of this application is described. Among them, Figure 1 This is the overall structural diagram of the air conditioner of this application; Figure 2 A first internal view of the air conditioner of the present application; Figure 3 A second internal view of the air conditioner of the present application; Figure 4 This is a first view of the first electric control box of this application; Figure 5 This is the second view of the first electric control box of this application.

[0047] like Figures 1 to 3 As shown, in a preferred embodiment, the air conditioner includes a housing 10, a fan 20, a condenser 30, an evaporator 40, a first electric control box 50, a second electric control box 60, and a compressor 70. The housing 10 includes a front panel 11 and a rear panel 12 arranged along the length direction of the housing 10, a base 13 and a top cover 14 arranged along the height direction of the housing 10, and two side panels 15, a first support rod 16, and a second support rod 17 arranged in the width direction of the housing 10. The front panel 11 is the air inlet side, and the rear panel 12 is the air outlet side. The first support rod 16 is arranged horizontally along the length direction of the housing 10. Two first support rods 16 are arranged on both sides of the width direction of the housing 10. The two ends of the first support rod 16 are respectively connected to the front panel 11 and the rear panel 12. The second support rod 17 is arranged vertically, and the upper and lower ends of the second support rod 17 are respectively connected to the two first support rods 16. A mounting frame can be formed between the front panel 11, the rear panel 12, the base 13, the first support rod 16, and the second support rod 17.

[0048] The fan 20 is arranged on the air outlet side of the shell 10, the condenser 30 and the evaporator 40 are both arranged in the shell 10, the evaporator 40 is located on the air inlet side of the condenser 30, and the evaporator 40 includes a refrigerant pipeline and a heat exchange pipeline, the first electrical control box 50 and the second electrical control box 60 are both arranged in the shell 10, and the first electrical control box 50 and the second electrical control box 60 are both located on the air inlet side of the condenser 30, the first electrical control box 50 is located at the top inside the shell 10, the evaporator 40 and the second electrical control box 60 are both arranged on one side of the width direction of the shell 10, and the second electrical control box 60 is located between the evaporator 40 and the condenser 30.

[0049] The first electric control box 50 includes a first box body 51 and a second box body 52. ​​The first box body 51 is connected to the second box body 52. ​​The second box body 52 is located on the side of the first box body 51 close to the condenser 30. The control board 61 is provided in the second electric control box 60. Figure 4 and Figure 5 As shown, a driver 53 is housed within the first electrical box 50. The driver 53 comprises a main body and multiple coils. At least some of the coils are housed within the second box 52, while the remaining coils are housed within the first box 51. A first heat sink 511 extends from the bottom of the first box 51 toward the air duct, while a second heat sink 521 extends from the second box 52 toward the side where the condenser 30 is located. A first connecting plate 54 is provided on one side of the bottom of the first electrical box 50 along its length, and two second connecting plates 55 are provided on the other side. Specifically, the first connecting plate 54 is a C-shaped plate, while the second connecting plates 55 are stepped plates.

[0050] Return to Reference Figure 2 and Figure 3 The first electric control box 50 and the second electric control box 60 are both arranged on the mounting frame. Figure 2 Taking the illustrated orientation as an example, the bottom of the first connecting plate 54 on the left side of the first electrical control box 50 is connected to the two upper first support rods 16, while the two second connecting plates 55 on the right side are each connected to one of the upper first support rods 16. The second electrical control box 60 is connected to the second support rods 17 along both sides of the housing 10 along its length via a third connecting plate 62, which serves as a connecting lug.

[0051] In this embodiment, when the air conditioner is in operation, the fan 20 is turned on, and at the same time, the compressor 70 compresses the refrigerant into a high-temperature, high-pressure gas. The refrigerant gas then enters the condenser 30 to exchange heat with the flowing air. The refrigerant is then throttled and reduced in pressure to become a low-temperature, low-pressure refrigerant liquid. The low-temperature, low-pressure refrigerant liquid enters the evaporator 40 to exchange heat with the heat exchange medium in the heat exchange pipeline, such as water, fluorine, etc. The refrigerant then passes through the gas-liquid separator and returns to the compressor 70 for the next refrigeration cycle. The heat exchange medium then brings the cold energy to the interior of the energy storage container, providing a basis for liquid cooling of batteries and the like inside the container.

[0052] It should be noted that in the prior art, the electrical control box is typically installed entirely at the top of the housing 10. In this embodiment, by separating the first and second electrical control boxes 50 and 60, the height of the condenser 30 can be adjusted, thereby increasing the heat exchange area of ​​the condenser 30 and improving the heat exchange efficiency of the condenser 30, thereby improving the cooling efficiency of the air conditioner. Furthermore, the driver 53 often generates a large amount of heat during operation. If heat is not dissipated promptly, the normal operation of the air conditioner may be affected. In this embodiment, during air circulation, part of the coil in the driver 53 can be dissipated through the second heat sink 521 on the second housing 52, while the remaining part can be dissipated through the first heat sink 511 on the first housing 51. This arrangement facilitates sufficient heat dissipation of the driver 53 and provides a foundation for stable operation of the air conditioner. Furthermore, since the control board 61 generates relatively little heat during operation, it can naturally dissipate heat in the flowing air through its own structure.

[0053] It will be understood by those skilled in the art that the specific arrangement of the first electric control box 50 and the second electric control box 60 is not fixed. In an alternative embodiment, the first electric control box 50 can be arranged above or below the second electric control box 60, that is, the first electric control box 50 and the second electric control box 60 are arranged along the height direction of the shell 10. At this time, the first electric control box 50 and the second electric control box 60 are both located on one side of the evaporator 40. During the air circulation process, the wind resistance generated by the first electric control box 50 and the second electric control box 60 can be reduced, thereby ensuring the effective heat exchange area of ​​the condenser 30 and improving the cooling energy efficiency of the air conditioner. In another alternative embodiment, the arrangement of the first heat sink 511 on the first electric control box 50 can be omitted, but considering the need to ensure the stable operation of the air conditioner, the arrangement of the first heat sink 511 is a better choice, or a heat sink can be arranged on the second electric control box 60 to further enhance the heat dissipation effect of the second electric control box 60. In another alternative embodiment, the second electrical control box 60 can be set on the other side of the shell 10. However, in order to avoid wind resistance affecting the cooling energy efficiency, it is a better choice to set the second electrical control box 60 on the same side as the evaporator 40. In addition, the specific arrangement of the second box body 52 is not static. In one alternative embodiment, the second box body 52 can be omitted. In this case, the driver 53 is entirely located in the first box body 51. In another alternative embodiment, when the second box body 52 is set, the second box body 52 can be set on the side of the first box body 51 close to the front panel 11. In another alternative embodiment, components such as switches or controllers can be set in the second box body 52. ​​In this case, the second heat sink 521 can also be omitted.

[0054] Those skilled in the art will also understand that while the housing 10 is configured as an assembled housing in this embodiment, its specific configuration is not fixed. In an alternative embodiment, the housing 10 can be configured as a single-piece housing. However, considering production efficiency and installation and maintenance, configuring the housing 10 as an assembled housing is a preferred option. Furthermore, the provision of a mounting frame is not essential. In an alternative embodiment, components such as the first and second electrical control boxes 50 and 60 can be mounted directly on the housing 10.

[0055] Of course, in the case of setting up a mounting frame, those skilled in the art can also change the connection method of each component to the mounting frame as needed. In an alternative embodiment, when the first electric control box 50 is set above the second electric control box 60, connecting ears can also be set on both sides of the length direction of the first electric control box 50. In this case, the first electric control box 50 can be connected to a second support rod 17 through the connecting ears on both sides. In another alternative embodiment, connecting plates can be set above and below the second electric control box 60, that is, the second electric control box 60 is connected to a first support rod 16 on both sides in the height direction. In this case, the setting of the second support rod 17 can be omitted. In addition, those skilled in the art can also change the number of the first support rod 16 and the second support rod 17 as needed, for example, setting the first support rod 16 to three, four or more.

[0056] Those skilled in the art will appreciate that although some embodiments described herein include certain features included in other embodiments but not other features, combinations of features from different embodiments are intended to be within the scope of this application and to form different embodiments. For example, in the claims of this application, any of the claimed embodiments may be used in any combination.

[0057] Thus far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present application.
