[0053] Techniques and equipment known to those of ordinary skill in the relevant art can not be discussed in detail, but should be considered part of the specification where appropriate.

[0054] In all examples shown and discussed herein, any specific values should be interpreted as merely illustrative, and not as a limitation. Thus, other examples of the example embodiments can have different values.

[0055] It should be noted that like reference numerals and letters refer to like items throughout the several views, and as a result, further discussion of such items is not required in subsequent views.

[0056] As shown in FIGS. 1-10, according to one aspect of the present application, a cooling structure is provided, comprising: a frame 3, and an air conditioning device, the end of the frame 3 comprising two vertically arranged connecting columns 31 and an upper connecting beam 32 and a lower connecting beam 33 connected to the upper end and the lower end of the two connecting columns 31, respectively; the air conditioning device is assembled at the end and at least partially located between the two connecting columns 31, or attached to the outside of the frame 3.

[0057] Specifically, with reference to FIGS. 1-3, in the present embodiment, the end of the cooling structure frame 3 is provided with two connecting columns 31 and an upper connecting beam 32 and a lower connecting beam 33 connected to the upper end and the lower end of the two connecting columns 31, so that the end forms a port capable of accommodating an air conditioning device. The present application places at least part of the air conditioning device between the two connecting columns 31, or attaches the air conditioning device to the outside of the frame 3, so that the air conditioning device can be fitted on the inside or outside of the port, or adjusted in the inside-outside direction of the frame 3 according to actual needs, so that the space at the port can be effectively utilized, while saving the space occupied by the distributed air conditioning or the special air conditioning compartment inside the frame 3, improving the available space inside the frame 3, and when the cooling structure is applied to energy storage equipment, more battery cells or larger capacity battery cabinets can be placed inside the frame 3, improving the energy density.

[0058] In the above embodiment, the cooling structure can be applied to a container or the like. If the end of the frame 3 is located in the first direction of the frame 3, at least part of the air conditioning device is located between the two connecting columns 31, that is, in the first direction, at least part of the air conditioning device coincides with the connecting column 31, so that in the first direction, at least part of the space in the width direction of the connecting column 31 is utilized. When the air conditioning device is attached to the end of the frame 3 and located outside the frame 3, the air conditioning device can simultaneously serve as an outer baffle corresponding to the end of the cooling structure, saving the setting space of the outer baffle, so that the cooling structure can have a larger assembly space in the first direction. In addition, attaching the air conditioning device to the outside of the frame 3 enables the frame 3 of the cooling structure to be designed separately, which is convenient for transportation and installation. The two connecting columns 31 can be corner columns.

[0059] Optionally, as shown in FIGS. 1-7, the air conditioning device includes a shell including a front panel and a rear panel 5, the front panel is provided with an air inlet 11 and a first air outlet 12, the front panel faces the outside of the frame 3, and the rear panel 5 faces the inside of the frame 3.

[0060] Specifically, the air conditioning device is arranged between the two connecting columns 31, and the front panel faces the outside of the frame 3, and the rear panel 5 faces the inside of the frame 3. When the air conditioning device fails, the front panel can be directly disassembled for maintenance, and various pipelines of the air conditioning device can be arranged on the inside of the rear panel 5. On the one hand, the appearance of the outside of the cooling structure is improved, and on the other hand, the pipeline components of the air conditioning device are connected to the cold plate and other equipment inside the frame 3 to realize the temperature control function of the air conditioning device on the equipment inside the frame 3. The air inlet 11 and the first air outlet 12 on the front panel are used for air intake and air exhaust of the air conditioning device, which faces the outside of the frame 3, which can improve the temperature control efficiency of the air conditioning device without affecting the ventilation of the equipment inside the frame 3. The number of air conditioning devices can be one, placed at one end of the frame 3, or two, placed at both ends of the frame 3, which is matched according to actual needs.

[0061] Optionally, as shown in FIGS. 1-3, the front panel is flush with the outer wall of the connecting column 31, so that the air conditioning device is located inside the frame 3.

[0062] Specifically, in this embodiment, the front panel of the air conditioning device is arranged flush with the outer wall of the connecting column 31, that is, the air conditioning device is arranged entirely inside the frame 3. On the one hand, the frame 3 can protect the air conditioning device to a certain extent, and on the other hand, the space in the thickness direction of the two connecting columns 31 can be effectively utilized, saving the space inside the cooling structure, so that more equipment can be assembled inside the cooling structure.

[0063] In actual application, the frame of the cooling structure can be a container or the like. In order to meet the assembly strength of the cooling structure, the strength of the connecting column 31 of the frame has certain requirements, which leads to the fact that the connecting column 31 usually needs to be set to a relatively wide size to meet the strength requirements of the cooling structure. In this case, there is a certain space in the width (or thickness) direction of the connecting column 31, and a part of the air conditioning device is arranged in this space, so that this part of space is effectively utilized. In an embodiment, the thickness of the connecting column 31 is 200 mm, and the air conditioner can be set to about 300 mm according to actual requirements, so that the rear panel 5 of the air conditioning device is staggered with the inner wall of the connecting column 31 by about 100 mm, which can be used for pipe running and the like.

[0064] Optionally, referring to FIGS. 1 to 3, the bottom of the air conditioning device is fixed on the lower connecting beam 33, and the side of the air conditioning device is fixed on the connecting column 31.

[0065] Specifically, the stable connection of the air conditioning device and the frame 3 affects the transportation stability of the entire cooling structure. In the embodiment, the bottom of the air conditioning device is fixed on the lower connecting beam 33, and the side of the air conditioning device is fixed on the connecting column 31, so that the air conditioning device can have stable connection. Among them, the bottom of the air conditioning device can be fastened on the lower connecting beam 33 by bolts, and the side can be fixed on the connecting column 31 by an angle piece.

[0066] Optionally, as shown in FIGS. 3 to 6, the shell further has two side panels 4, and a first gap is arranged between each of the two side panels 4 and the connecting column 31 opposite to it.

[0067] Specifically, in the embodiment, the first gap is arranged between the side panel 4 and the connecting column 31, which facilitates the assembly and disassembly of the air conditioning device. Among them, the size of the first gap can be designed according to actual requirements, for example, it can be designed to be 20 mm to 50 mm, which is convenient for operation and can maximize the use of the space between the connecting columns 31.

[0068] Optionally, as shown in FIGS. 2 and 4, the shell further has a top plate 6, and a second gap is arranged between the top plate 6 and the upper connecting beam 32.

[0069] Specifically, in the embodiment, the second gap is arranged between the top plate 6 and the upper connecting beam 32, which facilitates the assembly and disassembly of the air conditioning device. Among them, the size of the second gap can be designed according to actual requirements, for example, it can be designed to be 20 mm to 50 mm, which is convenient for operation and can maximize the use of the space between the connecting columns 31, and is also beneficial to the heat dissipation and ventilation of the air conditioning device.

[0070] Optionally, as shown in FIGS. 3 to 4, the side panel 4 is provided with a liquid supply port 120 and a liquid return port 121, and the liquid supply port 120 and the liquid return port 121 are exposed to the connecting column 31.

[0071] Specifically, in the embodiment, the liquid supply port 120 and the liquid return port 121 are arranged on the side panel 4 to facilitate connection and temperature control with the cooling plate and other devices inside the cooling structure. Arranging them on the side panel 4 not only facilitates the routing of the pipes of the air conditioning device, but also exposes them to the connecting column 31, i.e. the liquid supply port 120 and the liquid return port 121 are arranged on the side panel 4 at a position that is not blocked by the connecting column 31, so as to facilitate the disassembly of the pipes and maintenance. Among them, the inner end of the liquid supply port 120 and the liquid return port 121 is communicated with the liquid supply pipe and the liquid return pipe inside the air conditioning device, and the outer end is connected with the liquid supply pipe and the liquid return pipe outside.

[0072] In an embodiment, one end of the side panel 4 close to the front panel is aligned with the outer wall of the connecting column 31, and the other end of the side panel 4 close to the rear panel 5 is exposed to the inner wall of the connecting column 31, and the liquid supply port 120 and the liquid return port 121 are located in the area exposed to the inner wall of the connecting column 31 on the side panel 4. Among them, the inner wall is the surface opposite to the outer wall. For example, the size of the air conditioning device is within 2100*2300*300mm, and the installation space of the air conditioning device between the two connecting columns 31 of the frame 3 is 2138*2385*200mm, and the side panel 4 of the air conditioning device can be exposed to the inner wall of the connecting column 31 by 100mm, which can be used for the pipe routing of the liquid supply port 120 and the liquid return port 121.

[0073] Optionally, the rear panel 5 is flush with the outer wall of the connecting column 31, so that the air conditioning device is located outside the frame 3.

[0074] Specifically, in the embodiment, in order to save the space inside the cooling structure, the air conditioning device can be closely attached to the plane where the outer wall of the connecting column 31 is located. During transportation, the frame 3 of the cooling structure and the air conditioning device can be transported separately, and then assembled on site, improving the convenience of transportation.

[0075] Optionally, the cooling structure further comprises a base fixed to the outside of the frame 3, and the air conditioning device is arranged on the base and located outside the lower connecting beam 33. The air conditioning device and the base can be fixed to the end of the frame 3, so as to match air conditioning devices of different sizes and the frame 3, and also to make the assembly of the air conditioning device outside the frame 3 more stable. Among them, the water connection pipeline of the air conditioning device can be arranged below the air conditioning device, passing through the base, and routing L-shaped to connect with the frame 3 of the cooling structure. The electrical connection line of the air conditioning device can also be arranged below the air conditioning device, passing through the base, and routing L-shaped to connect with the frame 3 of the cooling structure.

[0076] Optionally, corner pieces are arranged at each corner of the end, and the air conditioning device is fixed to the frame 3 through the corner pieces. The air conditioning device is fixed to the frame 3 through the corner pieces, which on the one hand facilitates installation, and on the other hand improves the stability of the air conditioning device.

[0077] Optionally, as shown in FIGS. 3-4, the shell further has two side panels 4, and the second air outlet 41 is arranged on each of the two side panels 4.

[0078] Specifically, in the present embodiment, the shell is provided with two side panels 4, and the second air outlet 41 is arranged on each of the two side panels 4, so that the heat dissipation area of the air conditioner is increased, and the heat dissipation efficiency is improved. At the same time, the structure of the radiator inside the shell can be related to the distribution of the first air outlet 12 and the second air outlet 41.

[0079] Optionally, as shown in FIGS. 8-10, the air conditioner further comprises a condensation heat dissipation module 13, a water circulation module 14 and a control module 119 arranged in the shell; the condensation heat dissipation module 13 is located at the upper part of the shell, the water circulation module 14 is connected with the condensation heat dissipation module 13, and the control module 119 is located below the condensation heat dissipation module 13, and the control module 119 is used to control the operating state of the condensation heat dissipation module 13 and the water circulation module 14.

[0080] Specifically, in the present embodiment, the condensation heat dissipation module 13 of the air conditioner is arranged at the upper part of the shell, which is conducive to the upward movement and discharge of hot air, thereby improving the heat dissipation efficiency and further improving the refrigeration effect and energy efficiency ratio of the air conditioner. By connecting the water circulation module 14 with the condensation heat dissipation module 13, on the one hand, it ensures that the heat generated during the condensation process can be timely taken away by water circulation, maintaining the low-temperature state of the condensation heat dissipation module 13, and arranging the control module 119 below the condensation heat dissipation module 13 facilitates the connection of the waterway pipe and the wiring of the electrical connection harness, while reducing the occupation of the upper space and optimizing the space utilization.

[0081] The condensation heat dissipation module 13, the water circulation module 14 and the control module 119 are integrated in the shell, which improves the compactness of the entire air conditioner, occupies less space, and the modules are connected closely, which is convenient for maintenance and repair. Among them, the water circulation module 14 and the control module 119 can be arranged side by side below the condensation heat dissipation module 13, so that the internal structure of the air conditioner is more orderly, which is convenient for inspection and repair. As shown in FIG. 8, it is the approximate distribution position of the condensation heat dissipation module 13, the water circulation module 14 and the control module 119 in the shell, but it is not limited to this arrangement.

[0082] Optionally, as shown in FIGS. 8-10, the condensing heat dissipation module 13 includes a condensing fan 111, a condensing heat sink 112, a compressor 122, a drying filter 123, and a throttling valve 124; the heat dissipation surface of the condensing heat sink 112 is opposite to the first air outlet 12, the suction port of the condensing fan 111 is opposite to the air inlet 11, the exhaust port of the condensing fan 111 is opposite to the condensing heat sink 112, the compressor 122 and the drying filter 123 are both located at the back of the condensing heat sink 112; the air inlet of the condensing heat sink 112 is connected with the exhaust port of the compressor 122, the liquid outlet of the condensing heat sink 112 is connected with the drying filter 123 and the throttling valve 124 in sequence, and the liquid outlet of the throttling valve 124 and the air inlet of the compressor 122 are both connected with the water circulation module 14.

[0083] Specifically, in the present embodiment, through the close cooperation of the condensing heat sink 112 and the condensing fan 111, the exhaust port of the condensing fan 111 directly faces the heat dissipation surface of the condensing heat sink 112, which ensures that the cooling air can directly and effectively take away the heat on the condensing heat sink 112, thereby improving the heat exchange efficiency. The suction port of the condensing fan 111 is opposite to the air inlet 11, so that fresh air can smoothly enter the inside of the air conditioning device, providing sufficient cold source for condensation heat dissipation.

[0084] In addition, the air inlet of the condensing heat sink 112 is connected with the exhaust port of the compressor 122, which ensures that the high-temperature and high-pressure refrigerant gas can directly enter the condensing heat sink 112 for cooling, forming a complete air flow circulation path. After being cooled in the condensing heat sink 112, the refrigerant enters the drying filter 123 through the liquid outlet, removing the water and impurities therein to ensure the quality of the refrigerant and the stability of the system. The dried and filtered refrigerant passes through the throttling valve 124 to reduce the pressure, and then enters the air inlet of the compressor 122, completing the circulation of the refrigerant. This circulation mode ensures the stable flow and efficient utilization of the refrigerant in the system.

[0085] Further, the layout of the components of the condensing heat dissipation module 13 is compact, effectively utilizing the space, so that the structure of the entire air conditioning device is more compact and has a small footprint. The compressor 122 and the drying filter 123 are located at the back of the condensing heat sink 112, which not only facilitates connection but also saves space, improving the integration of the system. Efficient heat exchange and optimized air flow path make the circulation of the refrigerant in the system more smooth and efficient, thereby improving the energy efficiency ratio of the entire air conditioning device. The drying filter 123 can effectively remove the water and impurities in the refrigerant, ensuring the quality of the refrigerant and the stability of the system, further improving the energy efficiency ratio.

[0086] Optionally, as shown in FIGS. 8-10, the water circulation module 14 includes a plate heat exchanger 113, which includes a water side and a refrigerant side; the liquid outlet of the throttling valve 124 is connected to the liquid inlet of the refrigerant side, and the gas inlet of the compressor 122 is connected to the gas outlet of the refrigerant side.

[0087] Specifically, in the present embodiment, by providing the plate heat exchanger 113 in the water circulation module 14, it can form a complete refrigeration cycle with the throttling valve 124 and the compressor 122. The plate heat exchanger 113 has a compact structure and occupies a small area, which is conducive to the thinning of the air conditioning device. In addition, the plate heat exchanger 113 has a high heat recovery rate, which can improve the energy efficiency ratio of the system. It is easy to disassemble and assemble, and the number of plates can be increased or decreased according to actual needs, and applied to different refrigeration working conditions.

[0088] Optionally, as shown in FIGS. 3-4, the side panel 4 of the shell is provided with a second air outlet 41, and the condensation heat sink 112 is an L-shaped finned tube heat sink, and the heat dissipation surface thereof extends from the first air outlet 12 to the second air outlet 41.

[0089] Specifically, the condensation heat sink 112 is designed as an L-shaped finned tube heat sink, and the heat dissipation surface thereof extends from the first air outlet 12 to the second air outlet 41, which can significantly increase the heat dissipation area, thereby enhancing the heat dissipation effect. The fin structure of the finned heat sink can effectively increase the heat surface area and improve the air flow between the fins, which is conducive to faster heat transfer and dissipation. The arrangement of the first air outlet 12 and the second air outlet 41 allows air to flow through the condensation heat sink 112 from multiple directions, forming more uniform and effective air flow.

[0090] Optionally, as shown in FIGS. 3-5, the front panel includes an upper panel 1 and a lower panel 2, the upper panel 1 is arranged opposite to the outer side of the condensation heat dissipation module 13, and the lower panel 2 is arranged opposite to the outer side of the water circulation module 14 and the control module 119, and the air inlet 11 and the first air outlet 12 are both arranged on the upper panel 1.

[0091] Specifically, in the present embodiment, the front panel is divided into an upper panel 1 and a lower panel 2, so that the condensation heat dissipation module 13, the water circulation module 14 and the control module 119 each have an independent external cover, which facilitates individual maintenance or repair of each module when needed without the need to disassemble the entire front panel. In addition, the air inlet 11 and the first air outlet 12 are both arranged on the upper panel 1, corresponding to the condensation heat dissipation module 13, ensuring that the cold air required by the condensation heat dissipation module 13 can enter directly and effectively, and the high-temperature air can be discharged smoothly. This design optimizes the air flow organization and improves the condensation heat dissipation efficiency.

[0092] Further, the partition design of the front panel can reduce the noise and vibration generated by the condensation and heat dissipation module 13 during operation, and the influence on other modules (such as the water circulation module 14 and the control module 119). It helps to keep the air conditioner running quietly and stably. The upper panel 1 and the lower panel 2 correspond to different functional modules respectively. This design makes the structure of the front panel more reasonable and stable. At the same time, it is also convenient to optimize and reinforce each part separately during the design and manufacturing process.

[0093] Optionally, as shown in FIGS. 8-10, the condensation and heat dissipation module 13 is provided with two, and the two condensation and heat dissipation modules 13 are symmetrically arranged along the left-right direction of the upper panel 1.

[0094] Specifically, in this embodiment, two condensation and heat dissipation modules 13 are provided, and are arranged along the left-right direction of the upper panel 1, so that the air conditioner can obtain a larger heat dissipation area, and the heat dissipation efficiency is significantly improved. The design of the double condensation and heat dissipation modules 13 can enhance the stability of the structure of the air conditioner, so that they can support each other and reduce deformation or damage caused by vibration or external force.

[0095] Optionally, as shown in FIGS. 8-10, the water circulation module 14 includes a plate heat exchanger 113, a heater 114, an exhaust filter device 115, a circulating water pump 116, a liquid supply pipe, a liquid return pipe and a four-way reversing valve 118; the liquid return pipe is connected with the heater 114, the water side of the plate heat exchanger 113, the exhaust filter device 115, the circulating water pump 116 and the liquid supply pipe in sequence, and the liquid inlet and the gas outlet of the refrigerant side of the plate heat exchanger 113 are connected with the condensation and heat dissipation module 13; the four interfaces of the four-way reversing valve 118 are connected with the liquid supply pipe, the liquid return pipe, the heater 114 and the liquid outlet of the circulating water pump 116 respectively, and the four-way reversing valve 118 is used for switching the refrigeration function and the heating function of the air conditioner.

[0096] Specifically, in this embodiment, the plate heat exchanger 113 has high heat exchange performance, which ensures rapid and effective heat transfer between the water side and the refrigerant side. The unique corrugated plate design greatly improves the heat exchange efficiency, and the heat loss is small. Under the same pressure loss condition, the heat transfer coefficient of the plate heat exchanger 113 is 3-5 times higher than that of the traditional tube heat exchanger, which improves the energy efficiency ratio of the entire air conditioning system.

[0097] In addition, through the design of the four-way reversing valve 118, the refrigeration and heating functions in the water circulation module 14 are flexibly switched. This design enables the air conditioner to freely switch between refrigeration and heating modes according to environmental temperature and use requirements, meeting different needs. And the four interfaces of the four-way reversing valve 118 are connected with the liquid supply pipe, the liquid return pipe, the heater 114 and the liquid outlet of the circulating water pump 116 respectively, which ensures smooth and efficient switching process.

[0098] Further, the heater 114 is used to provide heat during the water circulation process, ensuring the stable operation of the system in heating mode. The heater 114 is small in volume, large in power, fast in thermal response, and high in temperature control accuracy, and can quickly provide the required heat. The exhaust filter device 115 is used to filter impurities and gases in the system, ensuring the cleanliness and stable operation of the system, which helps to prolong the service life of the system and improve its reliability.

[0099] In this embodiment, the various components in the water circulation module 14 are connected in a specific way to form an independent module. This modular design makes maintenance of the system more convenient and efficient, and individual components can be replaced or repaired without affecting the operation of the entire system.

[0100] Optionally, as shown in FIGS. 8-10, the water circulation module 14 further includes a pressure regulating tank 117 connected to the liquid supply pipe. The provision of the pressure regulating tank 117 can adjust the fluctuations in water supply pressure in the water circulation module 14, effectively stabilizing the water supply pressure and ensuring the stability and uniformity of the water flow.

[0101] Optionally, as shown in FIGS. 8-10, the water circulation module 14 further includes an air cooler 125, a three-way valve 126, and a proportional regulating valve 127, and the condensing heat sink module 13 includes a condensing heat sink 112. The air cooler 125 is located directly behind the condensing heat sink 112. The inlet and outlet of the air cooler 125 are connected to the inlet and outlet of the plate heat exchanger 113 through the three-way valve 126 and the proportional regulating valve 127 to form a parallel arrangement.

[0102] Specifically, in this embodiment, the parallel arrangement of the air cooler 125 and the plate heat exchanger 113 through the three-way valve 126 and the proportional regulating valve 127 allows the system to flexibly adjust the cooling or heating mode as needed. By adjusting the opening of the proportional regulating valve 127, the distribution of water flow between the air cooler 125 and the plate heat exchanger 113 can be accurately controlled, thereby achieving rapid switching and precise control of the cooling or heating function.

[0103] In cooling mode, the air cooler 125 can directly use the heat of the condensing heat sink 112 to cool the water without the need for secondary heat exchange through the plate heat exchanger 113, which can reduce heat loss and improve energy efficiency. In heating mode, by adjusting the three-way valve 126 and the proportional regulating valve 127, the heat of the plate heat exchanger 113 can be fully utilized to heat the water, also improving energy efficiency.

[0104] In addition, the surface cooler 125 is located directly behind the condensing heat sink 112, which can make full use of the heat discharged by the condensing heat sink 112, avoid heat accumulation in the system, and improve the stability of the system. At the same time, the parallel arrangement design makes the system have better redundancy, that is, even if one component fails, the system can still operate normally by adjusting other components. Among them, the design of flexible adjustment of cooling / heating mode and improvement of energy efficiency ratio makes the system more efficient in energy utilization and reduces energy consumption. At the same time, by optimizing the heat exchange and heat recovery process of the system, the impact on the environment can be reduced, meeting the requirements of energy saving and environmental protection.

[0105] Optionally, as shown in FIGS. 8-10, the surface cooler 125 and the condensing heat sink 112 both adopt parallel flow micro-channel heat sinks.

[0106] Specifically, the parallel flow micro-channel heat sink greatly increases the heat dissipation area due to its unique micro-channel design, so that the heat dissipation capacity of the heat sink is significantly improved under the same volume. Compared with traditional heat sinks, the parallel flow micro-channel heat sink can provide higher heat dissipation efficiency under the same conditions, so that the surface cooler 125 and the condensing heat sink 112 can dissipate heat faster and more effectively, thereby ensuring stable operation of the system.

[0107] In addition, since the micro-channel heat sink channel is very small, it can achieve compact structure while maintaining high efficiency of heat dissipation, so that the surface cooler 125 and the condensing heat sink 112 are more space-saving in terms of space occupation, which has an important influence on the thinning of the air conditioning device.

[0108] Optionally, as shown in FIGS. 8-10, the circulating water pump 116 is an electronic shield pump. Compared with traditional horizontal industrial centrifugal pumps, the space occupation is reduced by 60%, and the weight is reduced by 70%, further saving the space inside the air conditioner.

[0109] According to the second aspect of the present application, a storage device is provided, comprising: a battery module and the cooling structure of the first aspect, the battery module is located inside the frame 3, and the air conditioning device can be used to cool the battery module.

[0110] Specifically, since the cooling structure provided by the first aspect of the present application provides an independent air conditioning device, and the air conditioning device is arranged at the empty position between the two connecting columns 31 of the frame, the occupied space inside the frame 3 is saved, the arrangement space of the battery module is improved, and the energy density of the battery is improved. And the frame 3 of the cooling structure and the air conditioning device can be independent modules, which is convenient for transportation.

[0111] The above embodiments mainly describe the differences between the various embodiments, and the optimization features different between the various embodiments can be combined to form a better embodiment without contradiction. For the sake of brevity, details are not repeated here.
