[0040] Referring to Figure 1 , which shows a schematic structural diagram of a temperature control device for an energy storage system provided in this specification.

[0041] It can be understood that as Figure 2 and Figure 3 shown, a first device to be thermally managed 40 is provided inside an energy storage cabinet 30 of the energy storage system, and an air-cooled air conditioner 20 is provided outside the energy storage cabinet 30. The temperature control device 10 is used to adjust the temperature of the first device to be thermally managed 40 inside the energy storage cabinet 30 of the energy storage system. It can also be understood that the first device to be thermally managed 40 can be a PCS or an energy storage battery PACK. Figure 2 In

[0042] As Figure 1 shown, this specification provides a temperature control device 10 for an energy storage system, which may include:

[0043] A ventilation diversion module 110, which includes an air inlet 1110, a first air outlet 1120, and a second air outlet 1130;

[0044] The air inlet 1110 is correspondingly arranged with the air outlet of the air-cooled air conditioner 20, and the air inlet 1110 is used to inhale the cold air blown out by the air-cooled air conditioner 20; the air-cooled air conditioner 20 is arranged outside the energy storage cabinet 30;

[0045] The first air outlet 1120 is used to introduce the cold air inhaled by the air inlet 1110 into the first device to be thermally managed 40 from the first side of the first device to be thermally managed 40; the first device to be thermally managed 40 is arranged inside the energy storage cabinet 30;

[0046] The second air outlet 1130 is used to introduce the cold air inhaled by the air inlet 1110 into the first device to be thermally managed 40 from the second side of the first device to be thermally managed 40.

[0047] Specifically, air inlets are provided on both the first side and the second side of the first heat management device 40, so that the air blown out from the first air outlet 1120 and the second air outlet 1130 of the ventilation diversion module 110 enters the first heat management device 40 through the air inlets on both sides of the first heat management device 40, as Figure 3 shown. The first side and the second side of the first heat management device 40 are opposite sides. Generally, the first side and the second side of the first heat management device 40 are the left side and the right side of the first heat management device 40.

[0048] In this embodiment, after the ventilation diversion module diverts the cold air blown out from the air outlet of the air-cooled air conditioner, the cold air enters the first heat management device from the first side and the second side of the first heat management device, thereby more effectively promoting the full circulation of the cold air in the first heat management device for heat exchange, and thus more efficiently regulating the temperature of the first heat management device.

[0049] In one embodiment, continue to refer to Figure 1 , the ventilation diversion module 110 includes:

[0050] A housing 1140; the housing 1140 includes a first opening side and a second opening side, the first opening side is the air inlet 1110; a wind guide plate 1150 is provided on the second opening side, and the wind guide plate 1150 divides the second opening side into a first air outlet 1120 and a second air outlet 1130.

[0051] Specifically, referring to Figure 1 , the housing 1140 is a hollow structure surrounded by four sides. It should be noted that in order to clearly see the structure of the wind guide plate 1150 inside the housing 1140, Figure 1 the part of the housing 1140 close to the screen side is not drawn in. The shape of the housing 1140 can be set according to actual needs. It can be understood that when the housing 1140 is designed as a hollow rectangular parallelepiped with both ends open, the air guiding effect is the best. Taking the first opening side of the housing 1140 as the air inlet 1110 can make the cold air blown out from the air-cooled air conditioner 20 enter the housing 1140 more concentratedly, so that the utilization rate of the cold air blown out from the air-cooled air conditioner 20 is relatively high.

[0052] Using the wind guide plate 1150 to divide the cold air sucked into the air inlet 1110 into two parts, the position of the wind guide plate 1150 can be set according to actual needs, and the cold air volume entering both sides of the first heat management device 40 can be reasonably distributed, so that the temperature regulation of the first heat management device 40 is more balanced.

[0053] In one embodiment, continue to refer to Figure 1 , the wind guide plate 1150 includes a first plate 1151 and a second plate 1152;

[0054] One side of the first plate 1151 is connected to one side of the second plate 1152, and both the first plate 1151 and the second plate 1152 are connected to the third side and the fourth side of the housing 1140.

[0055] The first plate 1151 and the second plate 1152 of the air deflector 1150 can direct the cold air inhaled by the air inlet 1110 of the ventilation diversion module 110, that is, it can be more efficiently introduced into both sides of the first heat management device 40 to be heated.

[0056] It can be understood that a deflector can be provided at the edge of the second plate 1152 to direct the air blown out from the second air outlet 1130 downward, so that the air can enter the second side of the first heat management device 40 to be heated more quickly.

[0057] In one embodiment, with continued reference to Figure 1 , a plurality of through holes are formed in both the first plate 1151 and the second plate 1152.

[0058] Forming through holes in the first plate 1151 and the second plate 1152 can be used to balance the wind speed and wind pressure between the first plate 1151 and the housing 1140 (upper part) and between the second plate 1152 and the housing 1140 (lower part), and prevent the generation of eddy currents between the first plate 1151 and the second plate 1152 from affecting the flow direction of the air in the housing 1140.

[0059] The present application also provides an energy storage system. Referring to Figure 2 and Figure 3 , it can be understood that the energy storage cabinet 30 of the energy storage system includes a left compartment and a right compartment, and the left compartment and the right compartment are used to place PCS and / or energy storage battery PACKs. It can also be understood that only one of the left compartment and the right compartment can place PCS or energy storage battery PACKs, or PCS and energy storage battery PACKs can be placed in the two compartments respectively. Exemplarily, the left compartment places PCS or energy storage battery PACKs and the right compartment is empty, or the left compartment is empty and the right compartment places PCS or energy storage battery PACKs, or the left compartment places PCS and the right compartment places energy storage batteries, or the left compartment places energy storage batteries and the right compartment places PCS. Figure 2 In

[0060] As Figure 2 and Figure 3 shown, the energy storage system may include:

[0061] An energy storage cabinet 30;

[0062] A first heat management device 40, which is arranged on the first side inside the energy storage cabinet 30; a first fan 410 is arranged on the first heat management device 40;

[0063] The air-cooled air conditioner 20 is disposed on the first side outside the energy storage cabinet 30;

[0064] The first side inside the energy storage cabinet 30 and the first side outside the energy storage cabinet 30 are opposite sides;

[0065] For the temperature control device 10 for the energy storage system provided in the above embodiment, the temperature control device 10 is disposed between the air outlet of the air-cooled air conditioner 20 and the first device to be thermally managed 40;

[0066] The cold air blown out by the air-cooled air conditioner 20 enters the first device to be thermally managed 40 from the first side and the second side of the first device to be thermally managed 40 through the temperature control device 10 respectively, so as to promote the full circulation of the cold air blown out by the air-cooled air conditioner 20 in the first device to be thermally managed 40 for heat exchange. After heat exchange, the air is blown out from the air outlet of the first device to be thermally managed 40 under the action of the first fan 410.

[0067] Specifically, the first device to be thermally managed 40 may be a PCS or an energy storage battery PACK. The first side inside the energy storage cabinet 30 may be the left compartment or the right compartment. Correspondingly, the first side outside the energy storage cabinet 30 is the right side or the left side. Exemplarily, as Figure 2 and Figure 3 shown, the air-cooled air conditioner 20 is located on the right side outside the energy storage cabinet 30. Correspondingly, the first device to be thermally managed 40 is located on the left side inside the energy storage cabinet 30.

[0068] The air outlet of the air-cooled air conditioner 20 and the first device to be thermally managed 40 are connected through the temperature control device 10. As Figure 3 shown, the cold air blown out by the air-cooled air conditioner 20 enters the first device to be thermally managed 40 from the left and right sides of the first device to be thermally managed 40. Then, under the action of the first fan 410 on the first device to be thermally managed 40, the air after heat exchange with the first device to be thermally managed 40 is blown out from the air outlet of the first device to be thermally managed 40 (towards the cabinet door direction), and then enters the air inlet of the air-cooled air conditioner 20.

[0069] In this embodiment, the temperature control device disposed between the first device to be thermally managed and the air-cooled air conditioner shunts the cold air blown out from the air outlet of the air-cooled air conditioner, so that the cold air blown out from the air outlet of the air-cooled air conditioner can enter the first device to be thermally managed from the left and right sides, thereby effectively promoting the full circulation of the cold air in the first device to be thermally managed for heat exchange, and thus efficiently controlling the temperature of the first device to be thermally managed.

[0070] In one embodiment, with continued reference to Figure 2 , the energy storage system further includes:

[0071] A second fan 50;

[0072] The air blown out from the air outlet of the first device to be heat managed 40 is blown into the air inlet of the air-cooled air conditioner 20 under the action of the second fan 50.

[0073] Specifically, the second fan 50 can be arranged on the lower side of the compartment where the first device to be heat managed 40 is located, so as to blow the air blown out from the air outlet of the first device to be heat managed 40 into the air inlet of the air-cooled air conditioner 20 more quickly.

[0074] In one embodiment, at least one of the above-mentioned second fans 50 is provided. Under the action of multiple second fans 50, the air blown out from the air outlet of the first device to be heat managed 40 can be blown into the air inlet of the air-cooled air conditioner 20 more quickly.

[0075] In one embodiment, continue to refer to Figure 2 , the energy storage system further includes:

[0076] A second device to be heat managed 60, which is arranged on the second side inside the energy storage cabinet 30; a third fan 610 is arranged on the second device to be heat managed 60;

[0077] The air blown out from the air outlet of the first device to be heat managed 40 enters the second device to be heat managed 60 under the action of the air pressure generated by the third fan 610. After passing through the second device to be heat managed 60, the air blown out from the air outlet of the second device to be heat managed 60 is blown into the air inlet of the air-cooled air conditioner 20.

[0078] Specifically, the second device to be heat managed 60 and the first device to be heat managed 40 are respectively located in different compartments inside the energy storage cabinet 30. As Figure 2 shown, when the first device to be heat managed 40 is located on the left side inside the energy storage cabinet 30, the second device to be heat managed 60 is located on the right side inside the energy storage cabinet 30.

[0079] A third fan 610 is arranged on the second device to be heat managed 60. A part of the air blown out from the air outlet of the first device to be heat managed 40 can enter the second device to be heat managed 60 under the action of the third fan 610. After passing through the second device to be heat managed 60, the air blown out from the air outlet of the second device to be heat managed 60 is blown into the air inlet of the air-cooled air conditioner 20.

[0080] In the above solution, if the first device to be heat managed 40 is an energy storage battery, correspondingly, the second device to be heat managed 60 is a PCS; if the first device to be heat managed 40 is a PCS, correspondingly, the second device to be heat managed 60 is an energy storage battery.

[0081] It can be understood that in the above solution, when only the first device to be thermally managed 40 is included inside the energy storage cabinet 30, the thermal management of the energy storage system decouples the PACK and PCS. The air-cooled air conditioner 20 is only used to adjust the temperature of the first device to be thermally managed 40. At this time, the first device to be thermally managed 40 is usually the PACK, and the temperature adjustment of the PCS can be separately carried out using other modes, such as a fan, the air-cooled air conditioner 20, a heat exchanger (including an air-air heat exchanger or a water-air heat exchanger, etc.).

[0082] When both the first device to be thermally managed 40 and the second device to be thermally managed 60 are included inside the energy storage cabinet 30, the thermal management of the PACK and PCS is coupled, and one air-cooled air conditioner 20 is used to thermally manage both at the same time. Since the PACK is usually more sensitive to temperature, the air blown out by the air-cooled air conditioner 20 first passes through the PACK and then through the PCS, that is, the first device to be thermally managed 40 is the PACK and the second device to be thermally managed 60 is the PCS. However, when the order of the two is exchanged, the solution is still feasible.

[0083] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any change or replacement within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
