Description

Technical Field

[0001] This application relates to the field of liquid-cooled air conditioning technology, and in particular to a chassis, a liquid-cooled air conditioner and an energy storage system. Background Technology

[0002] An energy storage system is a system used to store and release electrical energy, involving the conversion between electrical and chemical energy, as well as the conversion between different types of electrical energy. In related technologies, commonly used energy storage systems, such as box-type and cabinet-type energy storage systems, integrate components such as battery packs, power conversion devices (e.g., inverters, converters, and power transducers containing various power electronic devices), and controllers into a cabinet. These systems are typically equipped with liquid-cooled air conditioning as a core device of the thermal management system.

[0003] Liquid-cooled air conditioners in related technologies are typically equipped with electrically driven components such as compressors, liquid cooling medium drivers (e.g., water pumps), water valves, and fans, all of which are integrated into a single chassis / frame.

[0004] In the process of developing this application, the inventors discovered that the connecting cables between the internal components of a liquid-cooled air conditioner are usually attached to the side wall of the chassis. When there is a leak inside the liquid-cooled air conditioner, the leaked liquid often drips onto the side wall of the chassis, which can easily cause the connecting cables between the components to become wet and short-circuit, thus affecting the normal operation of the liquid-cooled air conditioner.

[0026] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0027] Please see Figure 1 and Figure 2 The chassis 1000 includes a housing 10 and a splicing assembly 20. The splicing assembly 20 is disposed inside the housing 10 and is used for cable splicing to reduce the direct contact of cables with the inner wall of the housing 10.

[0028] For the aforementioned box 10, as Figure 1 and Figure 2 As shown, the enclosure 10 is provided with a receiving cavity 10a, which can be used for the installation of internal components of the liquid-cooled air conditioner. The enclosure 10 is basically cuboid in shape and is formed by multiple side plates connected to each other. It is understood that the connection methods between the multiple side plates 101 include, but are not limited to, welding, screwing, snap-fitting, etc. The shape of the enclosure 10 is not specifically limited in this application, and the enclosure 10 can be cuboid, cube, or other shapes.

[0029] In some embodiments, a control box 102 is provided on the housing 10, and the control box 102 is disposed in the receiving cavity 10a. The control box 102 is used for the installation of control components in the liquid-cooled air conditioner.

[0030] In some embodiments, please refer to the following: Figure 3The housing 10 is also equipped with a partition baffle 103, which is located on the first side wall 11 and divides the first side wall 11 into a first region 11a and a second region 11b. The partition baffle 103 can act as a barrier, reducing the flow of leaked liquid to the other region when it drips into one region, thereby reducing the impact of the leaked liquid on the electronic components located in the other region.

[0031] For the aforementioned overlapping component 20, such as Figures 2-4 As shown, the overlapping assembly 20 is disposed within the receiving cavity 10a. The overlapping assembly 20 includes an overlapping frame 21 and a fixing member 22. The overlapping frame 21 is connected to the first side wall 11 of the housing 10 via the fixing member 22. One end of the fixing member 22 is connected to the first side wall 11 of the housing 10, and the other end of the fixing member 22 is connected to the overlapping frame 21. A first space 20a is provided between the overlapping frame 21 and the first side wall 11, and the first space 20a communicates with the receiving cavity 10a. The overlapping frame 21 is used for cable overlapping. Users can use the overlapping frame 21 to overlap the connecting cables between internal components of the liquid-cooled air conditioner, so that the connecting cables are spaced apart from the first side wall 11 of the housing 10 by the first space 20a, thereby reducing the direct contact of the connecting cables with the first side wall 11 of the housing and reducing the risk of short circuits due to liquid immersion. It is understood that the connection methods between the fixing member 22 and the housing 10 include, but are not limited to, screwing, welding, riveting, snap-fitting, etc. In some embodiments, the lap joint 21 is located in the first region 11a.

[0032] In some embodiments, the splice bracket 21 includes a splice plate 211 and a connecting plate 212. One end of the fixing member 22 is fixed relative to the first sidewall 11, and the other end of the fixing member 22 is connected to one end of the connecting plate 212. The other end of the connecting plate 212 is connected to the splice plate 211. The splice plate 211 and the fixing member 22 are arranged opposite to each other, and the splice plate 211 and the connecting plate 212 are arranged at an angle. The splice plate 211 and the first sidewall 11 are spaced apart by a preset distance to form a first space 20a. The splice plate 211 is used for cable splicing, and the user can bind the cable to the splice plate 211 with a rope. It is understood that the length of the connecting plate 212 is related to the distance between the splice plate 211 and the first sidewall 11. The longer the length of the connecting plate 212, the greater the distance between the splice plate 211 and the first sidewall 11. Therefore, the length of the connecting plate 212 is not specifically limited in this application, and the user can set it according to actual needs.

[0033] In some embodiments, the overlapping plate 211 and the connecting plate 212 are integrally formed, and the overlapping plate 211 and the connecting plate 212 are arranged perpendicularly to each other, with an included angle of 90 degrees between them.

[0034] In some embodiments, please refer to the following: Figure 5 The fastener 22 includes a first connecting part 221 and a second connecting part 222. The first connecting part 221 and the second connecting part 222 are connected to each other and set at an angle. The second connecting part 222 is fixed to the first side wall 11. The first connecting part 221 is detachably connected to the connecting plate 212. The second connecting part 222 is fixed to the first side wall 11. This arrangement provides additional support points for the installation of the lap frame 21, which helps to improve the installation stability of the lap frame 21.

[0035] In some embodiments, the first connecting portion 221 is provided with a first connecting hole 221a, and the connecting plate 212 is provided with a second connecting hole 212a at one end near the fixing member 22. The second connecting hole 212a is opposite to the first connecting hole 221a. The overlapping bracket 21 is also provided with a connector 213, one end of which passes through the second connecting hole 212a and the first connecting hole 221a in sequence. The connector 213 is used to lock the connecting plate 212 and the fixing member 22, thereby realizing the connection between the connecting plate 212 and the fixing member 22. In some embodiments, the connector 213 is a rivet. It is understood that, in order to realize the connection between the connecting plate 212 and the fixing member 22, the connection methods include, but are not limited to, screw connection, welding, threaded connection, snap connection, magnetic connection, etc.

[0036] In some embodiments, there are multiple connecting plates 212 and multiple fasteners 22, with the number of connecting plates 212 corresponding to the number of fasteners 22. The arrangement of multiple connections and multiple fasteners 22 allows the overlapping frame 21 to be more securely installed on the first side wall 11 of the housing 10.

[0037] In some embodiments, the splice 21 further includes a first splice 21a, a second splice 21b, and a third splice 21c. The first splice 21a and the second splice 21b are arranged at an angle, and the second splice 21b and the third splice 21c are spaced apart. Since the first splice 21a and the second splice 21b are arranged at an angle, the first splice 21a can be used to splice cables in one direction, while the second splice 21b and the third splice 21c can be used to splice cables in another direction. The splices 21 in different directions can splice cables extending in different directions. In some embodiments, the first splice 21a and the second splice 21b are perpendicular to each other.

[0038] In this embodiment, a housing 10 and a splicing assembly 20 are provided. The housing 10 has a receiving cavity 10a, and the splicing assembly 20 is disposed within the receiving cavity 10a. The splicing assembly 20 includes a splicing frame 21, which is connected to the first side wall 11 of the housing 10. A first space 20a is provided between the splicing frame 21 and the first side wall 11, and the first space 20a communicates with the receiving cavity 10a. The splicing frame 21 is used for cable splicing. In this embodiment, the user can use the splicing frame 21 to splice the connecting cables between the internal components of the liquid-cooled air conditioner, so that the connecting cables are spaced apart from the first side wall 11 of the housing 10 by the first space 20a, thereby reducing the direct contact of the connecting cables with the first side wall 11 of the housing and reducing the risk of the connecting cables being soaked in liquid and short-circuiting.

[0039] This application also provides an embodiment of a liquid-cooled air conditioner, which includes the chassis 1000 as described above. The function and structure of the chassis 1000 can be found in the above embodiments, and will not be repeated here.

[0040] In some embodiments, such as Figure 6 As shown, the liquid-cooled air conditioner also includes a control module 2000, an air pump 3000, and a heating module 4000. The control module 2000, air pump 3000, and heating module 4000 are all disposed in the receiving cavity 10a. The air pump 3000 and the heating module 4000 are interconnected through pipelines. The control module 2000 and the air pump 3000 are electrically connected through a first connecting cable, and the control module 2000 and the heating module 4000 are electrically connected through a second connecting cable. The first connecting cable and the second connecting cable are both overlapped on the overlapping frame 21, and there is a first space between the first connecting cable and the second connecting cable and the first side wall of the chassis 1000. Users can use the splicing bracket 21 to splice the first and second connecting cables inside the liquid-cooled air conditioner, so that there is a first space between the first connecting cable and the first side wall of the enclosure, thereby reducing the direct contact between the first and second connecting cables and the first side wall of the enclosure 1000, and reducing the risk of the first and second connecting cables being soaked in liquid and short-circuiting.

[0041] In the liquid-cooled air conditioning system, the heating module 4000 can help increase the indoor temperature in heating mode. When the outdoor temperature is low and the heat pump heating alone is insufficient to meet the indoor demand, the heating module 4000 can supplement the heat and improve the heating efficiency.

[0042] In some embodiments, the liquid-cooled air conditioner further includes a first temperature sensor 5000 and a second temperature sensor 6000, both of which are electrically connected to the control component. The temperature sensors located at different positions can be used to monitor and sense temperature changes.

[0043] In some embodiments, the liquid-cooled air conditioner further includes inlet and outlet water temperature sensors, inlet and outlet water pressure sensors, refrigerant pipeline temperature sensors, a compressor, and a fan. The inlet and outlet water temperature sensors, inlet and outlet water pressure sensors, refrigerant pipeline temperature sensors, the compressor, and the fan are all connected to the control components. The inlet and outlet water temperature sensor lines, inlet and outlet water pressure sensor lines, refrigerant pipeline temperature sensor lines, compressor power lines, and fan power lines are all connected to the connecting bracket 21.

[0044] This application also provides an embodiment of an energy storage system, which includes a liquid-cooled air conditioner as described above. The function and structure of the liquid-cooled air conditioner can be found in the above embodiments, and will not be repeated here.

[0045] The above description is merely an embodiment of this application and does not limit the patent scope of this application.
