Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for energy storage systems, and in particular to a four-in-one system that integrates a liquid-cooled unit controller in an electrical control box. Background Technology

[0002] With the rapid development of energy storage technology, liquid-cooled units are increasingly being used in energy storage thermal management systems. Liquid cooling technology, through the efficient heat transfer capabilities of the liquid medium, ensures that the energy storage system maintains a stable temperature range under different operating conditions, extending equipment life and improving operating efficiency. However, existing liquid-cooled unit controllers still have the following shortcomings in practical applications:

[0003] 1. Issues with independent controller installation

[0004] Current liquid chiller controllers are typically designed as independent modules installed inside the liquid chiller unit. This distributed layout increases the complexity of equipment wiring and system space occupation, making installation and maintenance difficult, especially in vertical or horizontal energy storage thermal management systems where the lack of unified structural standards leads to low installation efficiency.

[0005] 2. Low system integration

[0006] Energy storage thermal management systems typically require filters, drivers (including reactors), DC-DC modules, and liquid chiller controllers to work together. Traditional separate designs result in independent modules, cumbersome wiring, and difficulty in achieving compact and highly integrated design goals, which is detrimental to the miniaturization and modularization of energy storage devices.

[0007] 3. Limited applicability and scalability

[0008] Existing liquid-cooled unit controllers are mostly customized designs, making it difficult to be compatible with different energy storage thermal management system layouts. In particular, for vertical and horizontal system applications, the lack of flexible interfaces and adaptable designs limits their widespread application.

[0009] Existing liquid chiller controllers are installed inside the liquid chiller unit, separate from the electrical control box. This results in high system complexity, cumbersome wiring, and occupancy of the limited installation space of the liquid chiller unit. It also hinders the advancement of lightweight and integrated designs, and the controller design struggles to simultaneously meet the needs of both vertical and horizontal energy storage thermal management systems. Furthermore, it lacks a unified installation scheme and flexible interface design. Therefore, we propose a four-in-one system integrating the liquid chiller unit controller within the electrical control box to solve the aforementioned problems. Utility Model Content

[0010] The purpose of this utility model is to solve the problems of existing liquid chiller controllers being installed inside the liquid chiller unit and separated from the electrical control box, resulting in high system complexity, redundant wiring, occupation of the limited installation space of the liquid chiller unit, and hindering the advancement of lightweight and integrated design. Furthermore, the controller design is difficult to simultaneously meet the needs of vertical and horizontal energy storage thermal management systems, and lacks a unified installation scheme and flexible interface design. Therefore, this utility model proposes a four-in-one system that integrates the liquid chiller unit controller within the electrical control box.

[0011] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] A four-in-one system integrating a liquid-cooled unit controller within an electrical control box includes an electrical control box body and multiple mounting slots symmetrically arranged on the inner walls of both sides of the electrical control box body, and further includes:

[0013] The mounting frame is located inside the electrical control box, and mounting ears are fixedly connected to the inner walls on both sides of the mounting frame.

[0014] The four-in-one mechanism includes a filter, a DC / DC converter, a controller, and a compressor driver, which are sequentially mounted on multiple mounting ears. Each of the filter, DC / DC converter, controller, and compressor driver is connected to multiple mounting ears with multiple fastening screws.

[0015] The disassembly mechanism is located on the mounting frame, which facilitates quick disassembly of the mounting frame.

[0016] Furthermore, a sensor interface is provided on the top horizontal surface of the electrical control box body to facilitate the insertion of sensors.

[0017] Furthermore, the top surface of the electrical control box is provided with an exhaust valve and an outlet for DC / DC output and a power inlet located next to the exhaust valve.

[0018] Furthermore, the bottom of the electrical control box body is provided with multiple outlet ports for PTC, compressor, heating belt and reactor output.

[0019] Furthermore, the disassembly mechanism includes a disassembly seat fixedly installed in the mounting frame, a rotating column rotatably connected to the disassembly seat, a hexagonal plate fixedly connected to one end of the rotating column, two take-up and release reels fixedly connected to the rotating column, two pull ropes respectively provided on the two take-up and release reels, and a connecting ring plate connected to one end of each pull rope.

[0020] Furthermore, both connecting ring plates are slidably connected to the disassembly seat, and a push-pull plate is fixedly connected to one end of each connecting ring plate. Multiple grooves are provided on both sides of the mounting frame, and a fixing spring is fixedly connected to the inner wall of each groove. One end of each fixing spring is fixedly connected to the two push-pull plates respectively. Multiple limiting slide grooves are provided in each groove, and the two ends of each push-pull plate are slidably connected to the multiple limiting slide grooves respectively. The multiple limiting slide grooves can slide and limit the two push-pull plates, so that the two push-pull plates can move horizontally and only move within the multiple limiting slide grooves, thus preventing them from detaching from the mounting frame.

[0021] Furthermore, each of the two push-pull plates is fixedly connected to one side with multiple fixing heads, one end of each fixing head being located in a multiple mounting groove, and the multiple mounting grooves can limit and fix the multiple fixing heads.

[0022] Compared with the prior art, the advantages of this utility model are:

[0023] 1. This solution integrates the liquid chiller unit controller into the electrical control box of the energy storage thermal management system, and integrates it with the filter, compressor driver (including reactor) and DC-DC module into a single design, achieving a highly integrated "four-in-one" design between the liquid chiller unit controller and other modules of the electrical control box;

[0024] 2. This solution utilizes a unified heat dissipation and protection structure to improve the overall thermal management performance and environmental adaptability of the system, and expands the application scenarios by providing flexible adaptation solutions for vertical and horizontal energy storage systems.

[0025] 3. In this design, the rotating column drives two take-up and unwinding reels to rotate simultaneously. By using the relative connection between the two pull ropes and the two take-up and unwinding reels, the two pull ropes can be wound up simultaneously when the two take-up and unwinding reels rotate. This also causes the two connecting ring plates to move closer to each other. The two connecting ring plates drive the two push-pull plates to move horizontally and compress multiple fixing springs. At the same time, this causes the two fixing heads to disengage from multiple mounting slots, thus quickly completing the disassembly of the mounting frame and enabling the simultaneous disassembly of the four-in-one structure.

[0026] This utility model has a simple structure. Through the integrated design of filter, driver (including reactor) and DC-DC module, a "four-in-one" structure is formed, which not only improves the system integration, but also enhances the environmental adaptability, reliability and thermal management performance of the controller. It is also suitable for vertical and horizontal energy storage thermal management systems, making it convenient for people to use. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] Reference Figures 1-4A four-in-one system integrating a liquid-cooled unit controller within an electrical control box includes an electrical control box body 1 and multiple mounting slots symmetrically arranged on the inner walls of both sides of the electrical control box body 1, and further includes:

[0037] Mounting frame 2 is located inside the electrical control box body 1, and mounting ears are fixedly connected to the inner walls on both sides of the mounting frame 2.

[0038] The four-in-one mechanism includes a filter 3, a DC / DC converter 4, a controller 5, and a compressor driver 11, which are sequentially mounted on multiple mounting ears. Each of the filter 3, DC / DC converter 4, controller 5, and compressor driver 11 is connected to multiple mounting ears with multiple fastening screws 12. Each individual component in the four-in-one mechanism can be disassembled or installed using the multiple fastening screws 12, which improves convenience.

[0039] Reference Figure 1 In this embodiment, the top horizontal surface of the electrical control box body 1 is provided with a sensor interface 6 for easy insertion of sensors. The top surface of the electrical control box body 1 is provided with an exhaust valve 7 and an outlet port 8 for DC / DC4 output and a power inlet port 9 located next to the exhaust valve 7. The setting of the power inlet port 9 facilitates the limitation of power lines, avoids messy wiring, and improves aesthetics. The bottom of the electrical control box body 1 is provided with multiple outlet ports 10 for PTC, compressor, heating belt and reactor output.

[0040] Reference Figure 2 and Figure 4 In this embodiment, the disassembly mechanism is provided on the mounting frame 2 to facilitate quick disassembly of the mounting frame 2. The disassembly mechanism includes a disassembly seat 13 fixedly installed in the mounting frame 2. A rotating column 14 is rotatably connected to the disassembly seat 13. A hexagonal plate 22 is fixedly connected to one end of the rotating column 14. Two take-up and release wheels 15 are fixedly connected to the rotating column 14. Two pull ropes 16 are respectively provided on the two take-up and release wheels 15. One end of each pull rope 16 is connected to a connecting ring plate 17.

[0041] Refer to Figure 3 and Figure 4In this embodiment, both connecting ring plates 17 are slidably connected to the disassembly seat 13. A push-pull plate 20 is fixedly connected to one end of each connecting ring plate 17. Multiple grooves 18 are provided on both sides of the mounting frame 2. A fixing spring 19 is fixedly connected to the inner wall of each groove 18. One end of each fixing spring 19 is fixedly connected to one of the two push-pull plates 20. When the fixing springs 19 release their elastic force, they can drive the two push-pull plates 20 to move. When the fixing springs 19 are in the released elastic force state, the two connecting ring plates 17 drive the two push plates 20 to move closer to each other. Multiple compressible fixed springs 19 are provided, and multiple limiting slide grooves 23 are provided in multiple slots 18. The two ends of the two push-pull plates 20 are slidably connected to the multiple limiting slide grooves 23 respectively. The multiple limiting slide grooves 23 can slide and limit the two push-pull plates 20, so that the two push-pull plates 20 can move horizontally and only move within the multiple limiting slide grooves, so as to avoid detaching from the mounting frame 2. Multiple fixing heads 21 are fixedly connected to one side of the two push-pull plates 20. One end of the multiple fixing heads 21 is located in multiple mounting grooves respectively. The multiple mounting grooves can limit and fix the multiple fixing heads 21.

[0042] The implementation principle of the four-in-one system integrating a liquid-cooled unit controller in an electrical control box according to an embodiment of this application is as follows: the filter 3, compressor driver 11 (including reactor), and DC / DC 4 module are integrated into a single design, forming a "four-in-one" structure. This simplifies the system layout, reduces wiring complexity, optimizes space utilization, unifies heat dissipation and protection, improves the overall thermal management performance and environmental adaptability of the system, and is suitable for standardized controller modules of vertical and horizontal energy storage thermal management systems. The interface is flexible, supports multiple installation methods, facilitates rapid deployment in different energy storage scenarios, and enhances adaptability and flexibility. When maintenance is required inside the electrical control box 1, the rotation of the hexagonal plate 22 drives the rotating column 14 to rotate, which in turn drives two take-up and release reels 15 to rotate simultaneously. The relative connection between the two pull ropes 16 and the two take-up and release reels 15 allows the two take-up and release reels 15 to rotate simultaneously. The two pull ropes 16 are wound up, causing the two connecting ring plates 17 to move closer together. The two connecting ring plates 17 drive the two push-pull plates 20 to move horizontally and compress multiple fixing springs 19. At the same time, the two fixing heads 21 are disengaged from multiple mounting slots, thus quickly completing the disassembly of the mounting frame 2. This allows for the simultaneous disassembly of the four-in-one structure. When the mounting frame 2 is installed after maintenance, the above operation is repeated, aligning the multiple fixing heads 21 with the multiple mounting slots. This causes the rotating column 14 to drive the two take-up and unwinding wheels 15 to rotate simultaneously, unwinding the two pull ropes 16. Simultaneously, the elastic force released by the multiple fixing springs 19 drives the two push-pull plates 20 to move. The two push-pull plates 20 drive the multiple fixing heads 21 to insert into the multiple mounting slots, thus quickly completing the installation of the mounting frame 2. This achieves rapid installation of the four-in-one structure, improving system integration and installation convenience.

[0043] All structures in this application can be customized in terms of material and length according to actual usage. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted accordingly.
