[0003] Currently, energy storage cabinets primarily rely on their internal structure to help dissipate heat from the battery pack. However, using only the internal structure to dissipate heat has limited effectiveness and cannot provide a suitable operating environment for the battery pack inside the cabinet.

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0035] New energy power generation systems include photovoltaic power generation and wind power generation, and they are generally equipped with a certain amount of outdoor energy storage cabinets. Traditional outdoor energy storage cabinets often use a single air conditioning cooling / heating or air-cooling system, which has problems such as high energy consumption and insufficient heat dissipation efficiency in high-temperature environments. Especially in harsh environments such as strong sunlight and high humidity, local overheating can easily occur inside the cabinet, leading to shortened battery life and even increasing the risk of thermal runaway.

[0036] Taking photovoltaic power generation as an example, large-scale photovoltaic power generation areas are generally high-temperature, high-heat environments with large temperature differences. The accumulation of solar radiation heat leads to excessively high internal temperatures within the storage unit, affecting battery life. Active cooling systems (such as air conditioning) are energy-intensive, reducing the overall efficiency of the energy storage system. Furthermore, energy storage units using a single heat dissipation method are ill-suited to cope with extreme temperature changes.

[0037] This application provides an energy storage cabinet with a composite temperature control structure, which significantly improves the heat dissipation efficiency and energy utilization rate of energy storage cabinets (especially outdoor energy storage cabinets) under high temperature and high radiation environments. The technical solution of the energy storage cabinet provided in this application is described below:

[0038] Figure 1 This is a schematic diagram of an energy storage cabinet structure provided in an embodiment of this application. Please refer to it. Figure 1 This application provides an energy storage cabinet 000, including: cabinet body 010, battery pack 020 and liquid cooler 030.

[0039] Cabinet 010 has a battery compartment C1 and an electrical appliance compartment C2. The outer surface of cabinet 010 has a heat insulation layer 011, which contains multiple hollow beads Z. For details regarding the heat insulation layer 011 on the outer surface of cabinet 010 and the multiple hollow beads Z within it, please refer to... Figure 2 , Figure 2 This is a schematic diagram of the outer surface structure of a cabinet provided in an embodiment of this application.

[0040] Battery pack 020 is fixed inside battery compartment C1.

[0041] The liquid chiller 030 is fixed inside the electrical compartment C2.

[0042] In summary, the insulation layer effectively blocks external heat from reaching the battery compartment, thus reducing the internal temperature to some extent. This reduces the heat dissipation requirements of the battery pack and lowers the power consumption of the liquid cooler within the cabinet. It also improves heat dissipation efficiency, providing a better operating environment for the battery pack. Furthermore, the presence of multiple hollow beads within the insulation layer, which have poor thermal conductivity, further reduces the overall thermal conductivity of the insulation layer, enhancing its insulation performance and preventing external energy transfer into the cabinet, thus better protecting the operating environment of the battery pack inside.

[0043] In this embodiment, the energy storage cabinet 000 can actively cool the battery pack 020 through the liquid cooler 030, and can also passively insulate the battery pack 020 through the heat insulation layer 011 on the outer surface of the cabinet 010, thus forming a composite temperature control structure of active cooling by the liquid cooler 030 and passive heat insulation by the heat insulation layer 011.

[0044] In one possible implementation, the insulation layer is a layered structure made of a heat-reflective material. For example, the insulation layer is a coating structure made of a heat-reflective paint.

[0045] Understandably, at this point, the insulation layer 011 can reflect not only strong sunlight but also sufficient cooling energy to ensure the internal temperature of the battery compartment C1 in the energy storage cabinet 000, creating a warm-in-winter and cool-in-summer effect. Correspondingly, the hollow beads Z mixed within the insulation layer 011 can prevent external heat from transferring into the cabinet 010 and also prevent external cooling energy from transferring into the cabinet 010.

[0046] It should be noted that, in this embodiment of the application, the energy storage cabinet 000 is mainly described using the reduction of the temperature inside the cabinet 010 as an example.

[0047] In addition, the energy storage cabinet 000 of this application can also ensure the humidity environment inside the cabinet 010 through the heat insulation layer 011, making it less likely to form condensation, thereby ensuring internal electrical safety.

[0048] In one feasible implementation, the heat insulation layer 011 employs a metal coating with a reflectivity ≥90% (such as ceramic microsphere composite material) to reduce solar radiation heat absorption.

[0049] In one feasible implementation, the heat-reflective coating used in the insulation layer 011 may have high heat reflectivity, heat radiation, low thermal conductivity, and heat shielding properties.

[0050] Specifically, regarding high heat reflectivity, the coating boasts a heat reflectivity of up to 90%, effectively reflecting sunlight and preventing most of the solar radiation heat from accumulating on the outer surface of the cabinet 010. This reduces the accumulation of solar radiation energy and prevents the heat from building up on the cabinet 010 surface, fundamentally eliminating the heat-causing factors caused by sunlight. For heat radiation, the heat-reflective coating incorporates high-emissivity materials with high infrared emission characteristics, rapidly radiating residual heat from the cabinet 010 surface to the external environment, further reducing the surface temperature. For low thermal conductivity, the heat-reflective coating incorporates hollow beads, such as nano-hollow glass microspheres with extremely low thermal conductivity. These microspheres, through close packing, form a highly efficient heat insulation layer 011 on the object's surface, preventing heat transfer within the object. For heat shielding, the coating incorporates inorganic heat shielding materials such as carbides, ensuring even better heat insulation performance.

[0051] For example, the heat-reflective coating used in the heat insulation layer 011 has the following formulation: nano hollow glass microspheres (30%), silicon carbide powder (15%), fluorocarbon resin (50%), and dispersant (5%).

[0052] The heat insulation layer 011 made using this heat-reflective coating formula can achieve a solar reflectivity of ≥90%, an infrared emissivity of ≥0.85, and a thermal conductivity of ≤0.04W / (m·K).

[0053] Figure 3This is a schematic diagram of a heat insulation layer structure provided in an embodiment of this application. Please refer to it. Figure 3 In some feasible embodiments, the insulation layer 011 includes multiple layers of sub-insulation layers K stacked together, the direction of which is perpendicular to the outer surface of the cabinet 010.

[0054] Since the heat insulation layer 011 is a coating structure made of heat-reflective paint, when the heat insulation layer 011 includes multiple layers of sub-heat insulation layers K, the thickness of a single sub-heat insulation layer K is relatively smaller than the overall thickness of the heat insulation layer 011. This facilitates layered spraying to form multiple layers of sub-heat insulation layers K.

[0055] To ensure the installation effect of the multi-layer sub-insulation layer K, after spraying each layer of sub-insulation layer K, a curing process can be used to bake the sub-insulation layer K for 30 minutes, for example, at a temperature of 60°C.

[0056] The insulation layer K consists of multiple layers stacked together, such as two, three, four, five, or six layers. The overall thickness of the insulation layer 011 is the sum of the thicknesses of the multiple sub-insulation layers K.

[0057] Figure 4 This is a schematic diagram of another insulation layer structure provided in an embodiment of this application. Please refer to it. Figure 4 In some feasible implementations, the multi-layer sub-insulation layer K includes: at least one first sub-insulation layer K1 and at least one second sub-insulation layer K2, wherein the at least one first sub-insulation layer K1 is located between the outer surface of the cabinet 010 and the at least one second sub-temperature control layer.

[0058] Among them, at least one second sub-insulation layer K2 contains multiple hollow beads Z.

[0059] The multi-layered sub-insulation layers K in the insulation layer 011 are further divided into at least one first sub-insulation layer K1 and at least one second sub-insulation layer K2, which are adjacent to each other along the stacking direction. At least one second sub-insulation layer K2, located relatively far from the outer surface of the cabinet 010, contains a plurality of hollow beads Z. Thus, the insulation layer 011 is connected to the outer surface of the cabinet 010 through the first sub-insulation layer K1, which does not contain hollow beads Z. This ensures the connection strength between the first sub-insulation layer K1 and the outer surface of the cabinet 010, and thus ensures the connection strength between the insulation layer 011 and the outer surface of the cabinet 010, giving the insulation layer 011 a certain degree of adhesion.

[0060] In some feasible implementations, the thickness of the first sub-insulation layer K1 may be less than or equal to the thickness of the second sub-insulation layer K2.

[0061] Since the second sub-insulation layer K2 contains multiple hollow beads Z, when the thickness of the second sub-insulation layer K2 is greater than or equal to the thickness of the first sub-insulation layer K1, it can provide a certain housing space for the multiple hollow beads Z in the second sub-insulation layer K2, which means that multiple hollow beads Z can be fixed in the second sub-insulation layer K2.

[0062] In some feasible implementations, the thickness of the insulation layer 011 is 200-300 μm. Within this thickness range, the temperature control effect of the insulation layer 011 can be well utilized, while also taking into account material and processing costs.

[0063] When processing the heat insulation layer 011, a high-pressure airless spraying device can be used to apply heat-reflective coatings in layers to form a multi-layer sub-heat insulation layer K.

[0064] For example, the thickness of a single sub-insulation layer K is 50-80 μm. Insulation layer 011 may include three, four, five, or six sub-insulation layers K.

[0065] When the thickness of the insulation layer 011 is 200-300μm and the thickness of the single-layer sub-insulation layer K is 50-80μm, this application takes the insulation layer 011 including four layers of sub-insulation layers K as an example for illustration.

[0066] The four-layer sub-insulation layer K may include three first sub-insulation layers K1 and one second sub-insulation layer K2, or it may include two first sub-insulation layers K1 and two second sub-insulation layers K2, or it may include one first sub-insulation layer K1 and three second sub-insulation layers K2.

[0067] When the second sub-insulation layer K2 has two or three layers, multiple hollow beads Z can be mixed in one of the second sub-insulation layers K2. For example, multiple hollow beads Z can be mixed in the second sub-insulation layer K2 furthest from the outer surface of the cabinet 010. Alternatively, hollow beads Z can be mixed in two or each of the multiple layers of second sub-insulation layers K2.

[0068] Figure 5 This is a schematic diagram of another cabinet outer surface structure provided in an embodiment of this application. Please refer to it. Figure 5 In some feasible embodiments, the outer surface of the cabinet 010 also has a protective layer 012, which is fixed to the side of the heat insulation layer 011 away from the outer surface of the cabinet 010.

[0069] Among them, the protective layer 012 is a coating structure made of hydrophobic and transparent material.

[0070] For example, a hydrophobic transparent protective film with a contact angle >150° can be rolled onto the side of the insulation layer 011 away from the outer surface of the cabinet 010 to prevent dust contamination from causing a decrease in reflectivity. In other words, the heat dissipation performance of the insulation layer 011 can be better protected by the protective layer 012.

[0071] After the protective layer 012 is fixed on the heat insulation layer 011, the protective layer 012 can be baked for 30 minutes using a curing process, for example, at a temperature of 60°C.

[0072] Please refer to Figure 5 In some feasible embodiments, the outer surface of the cabinet 010 also has an anti-corrosion layer 013. The anti-corrosion layer 013 is located between the outer surface of the cabinet 010 and the heat insulation layer 011, with one side of the anti-corrosion layer 013 fixedly connected to the outer surface of the cabinet 010 and the other side fixedly connected to the heat insulation layer 011.

[0073] For example, an epoxy zinc-rich primer with a thickness of 50 μm can be used to make the anti-corrosion layer 013. Typically, the outer side of the energy storage cabinet 000 is a sheet metal part, and the anti-corrosion layer 013 can improve the anti-corrosion performance of the energy storage cabinet 000.

[0074] After the anti-corrosion layer 013 is fixed on the outer surface of the cabinet 010, the anti-corrosion layer 013 can be baked for 30 minutes using a curing process, for example, at a temperature of 60°C.

[0075] Please refer to Figure 5 In some feasible embodiments, the outer surface of the cabinet 010 also has a substrate layer 014. The substrate layer 014 is located between the outer surface of the cabinet 010 and the anti-corrosion layer 013. One side of the substrate layer 014 is fixedly connected to the outer surface of the cabinet 010, and the other side is fixedly connected to the anti-corrosion layer 013. That is, the anti-corrosion layer 013 is indirectly connected to the outer surface of the cabinet 010 through the substrate layer 014.

[0076] The substrate layer 014 can be formed by sandblasting the outer surface of the cabinet 010. The substrate layer 014 has a cleanliness level of Sa2.5, for example, to ensure that the coating adhesion is ≥5Mpa.

[0077] Please refer to Figure 5 In some feasible embodiments, the outer surface of the cabinet 010 also has a heat-insulating layer 015. The heat-insulating layer 015 is located between the outer surface of the cabinet 010 and the substrate layer 014, with one side of the heat-insulating layer 015 fixedly connected to the outer surface of the cabinet 010 and the other side fixedly connected to the substrate layer 014.

[0078] The heat-insulating layer 015 can block external heat conduction and ensure the temperature environment inside the cabinet 010. The heat-insulating layer 015 is, for example, an asbestos insulation board.

[0079] Figure 6 This is a schematic diagram of another energy storage cabinet structure provided in an embodiment of this application. Please refer to it. Figure 6 In some feasible embodiments, the energy storage cabinet 000 further includes a control box 040 and a temperature detector 050. The control box 040 is fixed inside the electrical compartment C2. The temperature detector 050 is fixed to the cabinet 010, for example, fixed to the outer surface of the cabinet 010 to detect the external ambient temperature, or fixed inside the cabinet 010 to detect the ambient temperature inside the cabinet 010.

[0080] Figure 7 This is a schematic diagram of a temperature control principle provided in an embodiment of this application. Please refer to it. Figure 7 The control box 040 is communicatively connected to the temperature detector 050 and the liquid chiller 030. The temperature detector 050 detects the ambient temperature of the cabinet 010 and sends the ambient temperature to the control box 040. The control box 040 controls the operating power of the liquid chiller 030 according to the ambient temperature.

[0081] Assuming the external ambient temperature is T, the internal temperature should be (T-15). When T < 35℃, only liquid cooling self-circulation can be enabled; when 35℃ ≤ T < 45℃, liquid cooling low-power mode is activated; when T ≥ 45℃, liquid cooling full-power mode is activated.

[0082] Among them, the liquid-cooled low-power mode, for example, the liquid chiller 030 operates at 6KW power, and the liquid-cooled full-power mode, for example, the liquid chiller 030 operates at 10KW power.

[0083] The heat insulation layer 011 on the outer surface of the cabinet 010 effectively dissipates heat, reducing the temperature inside the cabinet 010. This allows the liquid chiller 030 inside the cabinet 010 to operate at an appropriate power level as needed, working in conjunction with the heat insulation layer 011 to control the temperature inside the cabinet 010 within a suitable range, rather than relying solely on the liquid chiller 030 to cool the cabinet 010. Furthermore, during temperature control, the liquid chiller 030 does not need to operate at full power continuously, thus effectively reducing power consumption and improving heat dissipation efficiency.

[0084] With the cooperation of the temperature controller and control box 040, the working power of the liquid chiller 030 can be selected more accurately according to the needs, further reducing power consumption and improving energy utilization.

[0085] In one feasible implementation, the energy storage cabinet 000 may further include an alarm 060, which is communicatively connected to the control box 040. When the temperature T detected by the temperature detector 050 is greater than the preset alarm temperature (e.g., 45°C), the control box 040 activates the alarm 060 to establish an alarm connection, so as to take timely measures to ensure the safe operation of the energy storage cabinet 000.

[0086] The energy storage cabinet in this embodiment is based on a combined thermal reflection and liquid cooling temperature control system. It blocks solar radiation heat input through an insulation layer and precisely removes battery heat through an internal microchannel liquid cooling system, achieving a reduction of over 30% in external heat load and over 30% (e.g., a 40% reduction) in liquid cooling system energy consumption. The cabinet provides an excellent internal environment, ensuring battery life and high charge / discharge efficiency for the entire energy storage unit. This energy storage cabinet is particularly suitable for thermal management of energy storage equipment in desert photovoltaic power plants and coastal wind farms.

[0087] In summary, the insulation layer effectively blocks external heat from reaching the battery compartment, thus reducing the internal temperature to some extent. This reduces the heat dissipation requirements of the battery pack and lowers the power consumption of the liquid cooler within the cabinet. It also improves heat dissipation efficiency, providing a better operating environment for the battery pack. Furthermore, the presence of multiple hollow beads within the insulation layer, which have poor thermal conductivity, further reduces the overall thermal conductivity of the insulation layer, enhancing its insulation performance and preventing external energy transfer into the cabinet, thus better protecting the operating environment of the battery pack inside.

[0088] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0089] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
