However, to improve the space utilization of the integrated compartment, more functional modules need to be integrated within a limited space, which leads to a significant increase in heat generation within the integrated compartment. Existing heat dissipation structures are unable to dissipate the accumulated heat in a timely manner, resulting in low heat dissipation efficiency of the integrated compartment. Utility Model Content

[0003] This application provides an electrical compartment and energy storage device that can solve the problem of low heat dissipation efficiency in the integrated compartment of existing electrical compartments.

[0004] To achieve the above objectives, the electrical compartment provided in this application includes a housing, which contains a comprehensive compartment. The comprehensive compartment is equipped with an air-cooling component, a first heating element, and a second heating element. The air-cooling component has an air outlet and an air return outlet. The first heating element is positioned closer to the air outlet than the second heating element, and the heat output of the first heating element is greater than that of the second heating element.

[0005] In some embodiments of this application, the air-cooled assembly includes a housing and a fan coil unit disposed within the housing. The housing is provided with an air outlet and an air return outlet, both of which connect the internal space of the housing and the outside of the housing. The air outlet is positioned towards the first heating device.

[0006] In some embodiments of this application, the integrated cabin has a first direction, and a first side and a second side disposed opposite to each other in the first direction, with the air outlet facing the first side and the return air outlet facing the second side, and the fan coil unit disposed between the air outlet and the return air outlet.

[0007] In some embodiments of this application, the first heating element is disposed between the first side and the housing, and the orthographic projection of the air outlet on the first side is located within the orthographic projection of the first heating element on the first side.

[0008] In some embodiments of this application, the integrated compartment has a second direction intersecting the first direction, the first heating device is disposed on one side of the second heating device in the second direction, and the electrical compartment further includes: A fan assembly is disposed on at least one side of the second heating device in a first direction, with the air outlet side of the fan assembly facing the second side.

[0009] In some embodiments of this application, the fan assembly includes: A first fan is disposed between the second heating element and the first side portion; The second fan is disposed between the second heating element and the second side; the air outlet side of the first fan and the air outlet side of the second fan are both oriented towards the second side.

[0010] In some embodiments of this application, the orthographic projections of the first fan and the second fan on the second side are located within the orthographic projection of the second heating device on the second side.

[0011] In some embodiments of this application, the distance between the housing and the second side is greater than or equal to the distance between the second fan and the second side.

[0015] The above-mentioned technical solution of this application has at least the following beneficial effects: This application achieves precise cooling with limited heat dissipation resources through a hierarchical layout of heat sources and efficient matching of airflow temperature gradients. Specifically, the first heat-generating device, with its high heat output, is positioned close to the air outlet, directly utilizing the low-temperature, high-speed airflow just discharged from the air-cooling components. This maximizes the cooling efficiency of the airflow's initial low-temperature state, where the temperature difference between the low-temperature, high-speed airflow and the first heat-generating device is greatest, resulting in the highest convective heat transfer efficiency. The second heat-generating device is positioned downstream of the airflow path, contacting the return airflow that has already absorbed some heat. However, this return airflow still possesses a certain cooling capacity to meet the heat dissipation requirements of the second heat-generating device. Thus, the design of this application avoids performance degradation of the first heat-generating device due to insufficient heat dissipation and achieves efficient utilization of limited airflow resources, thereby improving the overall heat dissipation efficiency of the integrated compartment.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] This application provides an electrical compartment and an energy storage device, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0024] With the rapid development of the energy storage market, the energy density and product integration of electrical compartment enclosures are continuously improving to meet higher energy storage efficiency and power output requirements.

[0025] However, in order to improve the space utilization of the integrated compartment, more functional modules need to be integrated in the limited space, but this will lead to a significant increase in heat generation in the integrated compartment. The existing heat dissipation structure is unable to dissipate the accumulated heat in time, thereby reducing the overall heat dissipation efficiency of the electrical compartment.

[0026] Therefore, please combine Figure 1 and Figure 2 The electrical compartment provided in this application includes a housing 1, which contains a comprehensive compartment 11. The comprehensive compartment 11 is equipped with an air-cooled component 2, a first heating element 3, and a second heating element 4. The air-cooled component 2 has an air outlet 2a and an air return outlet 2b. The first heating element 3 is located closer to the air outlet 2a than the second heating element 4, and the heat output of the first heating element 3 is greater than that of the second heating element 4.

[0027] This application achieves precise cooling with limited heat dissipation resources through a hierarchical layout of heat sources and efficient matching of airflow temperature gradients. Specifically, the first heat-generating device 3, with its high heat output, is positioned close to the air outlet 2a, directly receiving the low-temperature, high-speed airflow just discharged from the air-cooling component 2. This maximizes the cooling efficiency of the airflow's initial low-temperature state, where the temperature difference between the low-temperature, high-speed airflow and the first heat-generating device 3 is greatest, resulting in the highest convective heat transfer efficiency. The second heat-generating device 4 is positioned downstream of the airflow path, contacting the return airflow that has absorbed some heat. However, this return airflow still possesses a certain cooling capacity to meet the heat dissipation requirements of the second heat-generating device 4. Thus, the design of this application avoids performance degradation of the first heat-generating device 3 due to insufficient heat dissipation and achieves efficient utilization of limited airflow resources, thereby improving the heat dissipation efficiency of the electrical compartment.

[0028] In other words, the air-cooled component 2 draws in air from the return air inlet 2b, cools it internally, and then discharges the low-temperature, high-speed airflow from the outlet 2a. An airflow path is formed between the outlet 2a and the return air inlet 2b. Figure 1 As indicated by the black arrows in the image, the first heating element 3 is positioned near the air outlet 2a, at the beginning of the airflow path. The second heating element 4 is positioned away from the air outlet 2a, at the end of the airflow path. When the airflow flows from the air outlet 2a to the return air outlet 2b, it passes through the area where the first heating element 3 is located, then continues to the area where the second heating element 4 is located, and finally flows back to the return air outlet 2b. Alternatively, it can be understood that after the airflow exits from the air outlet 2a, it flows sequentially through the first heating element 3 and the second heating element 4, exchanging heat with each of them, before entering the air-cooled assembly 2 through the return air outlet 2b for cooling and then exiting from the air outlet 2a, thus forming a heat dissipation cycle.

[0029] Based on the above embodiments, the air-cooled assembly 2 includes a housing 21 and a fan coil unit 22 disposed within the housing 21. The housing 21 is provided with an air outlet 2a and a return air outlet 2b, both of which connect the internal space of the housing 21 to the outside of the housing 21. The air outlet 2a is positioned facing the first heating element 3. Within the housing 21, the fan coil unit 22 undergoes forced heat exchange with the airflow entering through the return air outlet 2b via a cooling medium such as refrigerant or cooling water, forming a low-temperature, high-speed airflow. Positioning the air outlet 2a towards the first heating element 3 allows the newly heated, low-temperature, high-speed airflow to directly flow through the high-heat area, quickly carrying away the heat from the first heating element 3. Subsequently, the return air outlet 2b draws in the heated return airflow, which is then cooled again by the fan coil unit 22, thus forming a heat dissipation cycle.

[0030] For example, the aforementioned housing 21 includes a first housing 211 and a second housing 212, which overlap each other to form an installation cavity. The fan coil unit 22 is disposed within the installation cavity, and both the air outlet 2a and the air return outlet 2b are connected to the installation cavity and the exterior of the housing 21, i.e., the integrated compartment 11. The split design of the housing 21 allows for the individual disassembly of the fan coil unit 22 for cleaning or replacement. Furthermore, the fan coil unit 22 is placed within a completely enclosed installation cavity, physically isolated from the external environment of the housing 21, which prevents the cooled low-temperature airflow from leaking through gaps in the housing 21 before reaching the air outlet 2a, thus avoiding heat loss.

[0031] In other embodiments, the air-cooled assembly 2 may also include a fan, a finned radiator, and a housing 21. The fan drives airflow through the finned radiator, and a cooling medium such as cooling water or refrigerant is introduced into the radiator. The heat exchange area is increased by the fins, which quickly removes the heat from the airflow.

[0032] For example, the integrated compartment 11 has a first side 111 and a second side 112 arranged opposite each other in the first direction Y. An air outlet 2a faces the first side 111, and a return air outlet 2b faces the second side 112. A fan coil unit 22 is disposed between the air outlet 2a and the return air outlet 2b. In other words, the air outlet 2a and the return air outlet 2b on the housing 21 are arranged opposite each other along the first direction Y, with the fan coil unit 22 located between them. This creates a shortest straight airflow path within the housing 21. This design reduces energy loss during airflow and ensures that the airflow exiting from the air outlet 2a remains at a low temperature and high speed, blowing towards the first heating element 3, thus achieving rapid heat dissipation of the first heating element 3.

[0033] The first heating element 3 is positioned between the first side portion 111 and the housing 21. The orthographic projection of the air outlet 2a on the first side portion 111 lies within the orthographic projection of the first heating element 3 on the first side portion 111. This ensures that the low-temperature, high-speed airflow discharged from the air outlet 2a directly acts on the surface of the first heating element 3, preventing airflow dispersion or overflow to other areas. Simultaneously, matching the projections of the air outlet 2a and the first heating element 3, that is, matching their installation positions, eliminates the need for additional deflectors to adjust the airflow direction, thereby further improving the space utilization within the integrated compartment 11.

[0034] For example, the orthographic projection of the air outlet 2a on the first side 111 completely covers the orthographic projection of the first heating element 3 on the first side 111. The full-coverage airflow avoids localized high-temperature areas formed at the edges or corners of the first heating element 3 due to lack of airflow, making the temperature distribution on the surface of the first heating element 3 more uniform and preventing localized overheating that could lead to material performance degradation.

[0035] Please continue to refer to Figure 1 The integrated compartment 11 has a second direction Z intersecting the first direction Y. Specifically, the first direction Y can be approximately perpendicular to the second direction Z, meaning the angle between the first direction Y and the second direction Z can be between 85° and 90°. The electrical compartment also includes a liquid-cooled unit 5, which is located within the integrated compartment 11 and positioned on one side of the air-cooled assembly 2 along the second direction Z. A second heating element 4 is located on the other side of the air-cooled assembly 2 along the second direction Z. The liquid-cooled unit 5 is in fluid communication with the fan coil unit 22 and is used to cool the cooling medium within the fan coil unit 22. The liquid-cooled unit 5 and the air-cooled assembly 2 are arranged along the second direction Z, forming a layered three-dimensional structure that fully utilizes the height space of the integrated compartment 11. This layout reduces the overlap between the two along the first direction Y, allowing the remaining space within the integrated compartment 11 to accommodate more functional modules and improving the overall energy density of the electrical compartment.

[0036] Furthermore, by reusing the existing liquid-cooled unit 5 in the electrical compartment to cool the fan coil unit 22, there is no need to deploy an additional independent cooling system. This avoids redundant investment in the cooling system, saving costs, and also reduces redundant configurations in the cooling system, simplifying the architecture of the electrical compartment. The liquid-cooled unit 5 can deliver low-temperature cooling medium to the fan coil unit 22 in a short time by adjusting the flow rate and temperature of the cooling medium. Combined with the high-speed airflow of the fan, this achieves rapid cooling of the first heat-generating device 3, avoiding the risk of thermal runaway caused by local overheating.

[0037] In some embodiments, in the second direction Z, the first heating element 3 is disposed between the liquid cooling unit 5 and the second heating element 4, avoiding their overlapping layout on the same plane, thus making more rational use of the space within the integrated compartment 11. Simultaneously, arranging the high-heat-generating first heating element 3 closer to the liquid cooling unit 5 (i.e., the first heating element 3 is positioned closer to the liquid cooling unit 5 than the second heating element 4), and having the air-cooled assembly 2 and the first heating element 3 arranged sequentially in the first direction Y, not only significantly shortens the connection distance between the liquid cooling unit 5 and the fan coil unit 22, but also optimizes the pipeline layout path, greatly reducing the length of the cooling medium delivery pipeline. This saves valuable space within the compartment and reduces pipeline pressure drop and energy consumption.

[0038] Please continue to refer to Figure 1 In this embodiment, the first heating element 3 is disposed on one side of the second heating element 4 in the second direction Z. The electrical compartment also includes a fan assembly 6, which is disposed on at least one side of the second heating element 4 in the first direction Y, with the air outlet side of the fan assembly 6 facing the second side 112. The fan assembly 6, disposed on at least one side of the second heating element 4 in the first direction Y, can generate airflow that directly acts on the second heating element 4. This design has a dual function: firstly, it can effectively compensate for any blind spots in the airflow coverage area of ​​the second heating element 4, eliminating localized heat dissipation dead zones. Secondly, the fan assembly 6 can adjust the airflow speed through the second heating element 4, making the airflow speed more compatible with the current temperature of the second heating element 4, avoiding energy waste caused by the fan assembly 6 continuously running at full speed. This design not only ensures that the heat generated by the second heating element 4 can be quickly carried away by the airflow, but also promotes the smooth return of hot air to the return air vent 2b, preventing heat accumulation in the area where the second heating element 4 is located, ultimately achieving uniform temperature distribution within the integrated compartment 11 and improving the stability and efficiency of the overall heat dissipation system.

[0039] For example, the fan assembly 6 includes a first fan 61 and a second fan 62. The first fan 61 is disposed between the second heating element 4 and the first side portion 111. The second fan 62 is disposed between the second heating element 4 and the second side portion 112. The air outlet side of the first fan 61 and the air outlet side of the second fan 62 both face the second side portion 112. The first fan 61 and the second fan 62 are respectively located on opposite sides of the second heating element 4 in the first direction Y, which can eliminate the cooling blind zone caused by the installation deviation of the single-sided fan or the obstruction of the second heating element 4, and ensure that the surface temperature distribution of the second heating element 4 is uniform. The airflow starts from the first fan 61 and passes directly through the surface of the second heating element 4, and is then discharged by the second fan 62, avoiding turbulence such as eddies or reverse flow caused by airflow convergence, ensuring that the airflow always flows through the surface of the second heating element 4 at a stable speed and direction, and significantly improving the convective heat transfer efficiency.

[0040] The orthographic projections of the first fan 61 and the second fan 62 on the second side 112 are located within the orthographic projection of the second heating device 4 on the second side 112, ensuring that the first fan 61 and the second fan 62 can directly act on the second heating device 4, avoiding the formation of local high temperature areas on the edge of the second heating device 4 in the first direction Y due to the airflow not reaching it, and the uniform airflow distribution makes the surface temperature of the second heating device 4 more uniform.

[0041] The first fan 61 provides the initial driving force, pushing the airflow towards the second heating element 4, while the second fan 62 further ensures that the airflow can fully cover all parts of the second heating element 4 and promptly exhausts the heat-exchanged airflow. The rational arrangement of the two fans can better guide the airflow path inside the integrated compartment 11, enabling the airflow to cover each heating area more evenly, resulting in a more balanced temperature distribution within the integrated compartment 11.

[0042] In some embodiments, the orthographic projections of the first fan 61 and the second fan 62 on the second side 112 coincide, meaning that their outlet sides form completely overlapping airflow outlets on the second side 112. The two fans work collaboratively in the same area, and the airflow effects they produce can be superimposed. The initial thrust provided by the first fan 61 combined with the suction force of the second fan 62 creates a stronger airflow on the surface of the second heating device 4, increasing the airflow rate through the second heating device 4 per unit time, thereby more effectively removing heat. Simultaneously, this arrangement also balances the airflow pressure distribution around the second heating device 4, preventing excessively high or low local airflow pressure, ensuring that airflow can uniformly pass through all parts of the second heating device 4, further improving the uniformity and stability of heat dissipation.

[0043] If the distance between the housing 21 and the second side 112 is less than the distance between the second fan 62 and the second side 112, the airflow, after being blown out from the second fan 62, may quickly come into contact with the wall of the second side 112 due to the limited space, causing a sudden change in airflow direction and generating turbulence and eddies. Therefore, this application ensures that the distance between the housing 21 and the second side 112 is greater than or equal to the distance between the second fan 62 and the second side 112, allowing the airflow to have more open space after being blown out from the second fan 62, enabling it to flow more smoothly and reducing turbulence and energy loss.

[0044] In some embodiments, the first fan 61 is disposed offset from the first heating device 3 in the first direction Y, and the first fan 61 is closer to the first side 111 than the first heating device 3, so that the low-temperature high-speed airflow blown out by the air-cooling component 2 flows through the first heating device 3 and is then drawn into the first fan 61 from the suction side facing the first side 111, thereby eliminating the heat dissipation dead corner that may exist near the first side 111 of the first heating device 3, and allowing the low-temperature high-speed airflow to fully contact each area of ​​the first heating device 3, so that the surface temperature distribution of the first heating device 3 is more uniform.

[0045] Please refer to Figure 1 and Figure 3 In this embodiment, the first heat-generating device 3 includes a frequency converter module 31 and a power supply module 32 arranged along the first direction Y. The second heat-generating device 4 includes a fuse 41 and conductive busbars 42 connected to both ends of the fuse 41. The frequency converter module 31 and the power supply module 32, as high-power electronic devices, generate considerable heat during operation. They are collectively referred to as the first heat-generating device 3 for centralized heat dissipation via an independent fan assembly. The fuse 41 and the conductive busbars 42 generate relatively low heat and can be cooled independently through natural cooling or a small fan. Specifically, the frequency converter module 31 is positioned between the power supply module 32 and the air-cooling assembly 2.

[0046] The conductor bar 42 at one end of fuse 41 is used for electrical connection with the energy storage converter, and the conductor bar 42 at the other end of fuse 41 is used for electrical connection with the medium-voltage switchgear. Fuse 41 electrically isolates the energy storage converter from the medium-voltage switchgear, forming an independent protection circuit. When an overload or short-circuit fault occurs in the circuit, fuse 41 can quickly cut off the current, preventing the fault current from spreading to the energy storage converter or the medium-voltage switchgear, thus accurately protecting critical equipment from damage.

[0047] It should be noted that the frequency converter module 31 is used to adjust the speed of the compressor, water pump, and fan of the liquid chiller unit 5, thereby regulating the cooling capacity of the liquid chiller unit 5. The compressor does work on the refrigerant, increasing its pressure and temperature. The high-temperature, high-pressure refrigerant gas releases heat after entering the condenser, then decreases in pressure and temperature through the throttling device, and finally absorbs heat and vaporizes in the evaporator, completing the refrigeration cycle. The water pump drives the cooling medium to circulate in the pipeline. The fan generates airflow through the rotation of its blades, forcing the air to contact the surface of the condenser or radiator for heat exchange.

[0048] In some embodiments of this application, this application also provides an energy storage device, which includes an electrical compartment as described in any of the above technical solutions. The housing 1 of the electrical compartment is configured as a container for the energy storage device. Since the container in the energy storage device and the housing 1 in the electrical compartment have the same technical features, they can solve the same technical problems and achieve the same technical effects.

[0049] Please refer to Figure 4 The container also includes a battery compartment 12, which ensures the safety of the energy storage equipment through functional zoning. The battery compartment 12 serves as the physical carrier of the battery modules 121 and undertakes the core task of energy storage. Thermal runaway or electrical faults in the battery compartment 12 are confined to an independent space, preventing them from affecting the functional modules within the integrated compartment 11. Furthermore, the battery compartment 12 can be opened independently for battery module 121 replacement or repair without entering the integrated compartment 11. The air-cooled components 2, the first heating element 3, and the second heating element 4 within the integrated compartment 11 can also be maintained independently, shortening maintenance time.

[0050] For example, the battery compartment 12 and the integrated compartment 11 are arranged sequentially along a third direction X, according to this application. Figure 4 The diagram shows a configuration with multiple battery compartments 12. These multiple battery compartments 12 are also arranged along a third direction X. The first direction Y, the second direction Z, and the third direction X intersect each other. To a certain extent, the first direction Y can be understood as the depth direction of the container, the second direction Z as the height direction of the container, and the third direction X as the width direction of the container. From the top to the bottom of the container, the liquid cooling unit 5, the first heating element 3, and the second heating element 4 are arranged sequentially.

[0051] In the embodiment where the electrical compartment includes the liquid cooling unit 5, the liquid cooling unit 5 can also cool the battery module 121 in the battery compartment 12. The liquid outlet of the liquid cooling unit 5 is connected to the liquid inlet of the battery module 121 through a pipeline, and the liquid return end of the liquid cooling unit 5 is connected to the liquid outlet of the battery module 121 through a pipeline.
