Description

Technical Field

[0001] This utility model relates to the field of heat dissipation system technology, specifically to a split liquid cooling heat dissipation system for charging piles. Background Technology

[0002] With the booming development of the new energy vehicle industry, the demand for high-power fast charging continues to grow. Split-type charging piles, with their advantages of flexible modular layout and strong power expansion capabilities, are widely used in high-power charging scenarios such as large charging stations and highway service areas. Compared with integrated charging piles, split-type charging piles separate the charging module from the charging gun. The charging module is centrally installed in an external cabinet and connected to the terminal charging gun through cables and pipes. Although this structural design improves space utilization and maintenance convenience, it also places higher demands on the heat dissipation system.

[0003] Currently, the common heat dissipation methods for split-type charging piles mainly include air cooling and liquid cooling.

[0004] Air cooling uses forced convection by installing cooling fans. Although it is simple in structure and low in cost, it is limited by the low thermal conductivity and high flow resistance of air, making it difficult to meet the heat dissipation requirements of high-power charging modules. In particular, the heat dissipation effect is significantly reduced in high-temperature environments or long-term continuous operation scenarios.

[0005] While liquid cooling can effectively improve heat dissipation efficiency, existing split-type charging pile liquid cooling systems still have the following problems: First, they cannot accurately match local heat generation needs, resulting in significant energy waste.

[0006] Secondly, the modularity is low, and maintenance requires stopping the machine and disassembling the entire equipment.

[0007] Based on this, this utility model designs a split liquid cooling heat dissipation system for charging piles to solve the above problems. Utility Model Content

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0040] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0041] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-11 A split liquid cooling heat dissipation system for charging piles includes a control cabinet 1, a liquid cooling heat dissipation component 3, a charging pile 4, a central control module 5, a communication module 6, and a temperature sensor 7. The inside of the control cabinet 1 is connected to the liquid cooling heat dissipation component 3, and multiple charging piles 4 are connected to the outside of the control cabinet 1. Multiple installation and disassembly modules 2 are installed at equal intervals inside the control cabinet 1, and the multiple installation and disassembly modules 2 are respectively connected to the liquid cooling heat dissipation component 3.

[0042] The central control module 5 and the communication module 6 are both fixedly installed inside the control cabinet 1. The installation position can be selected according to actual needs. The central control module 5 is connected to the communication module 6 and the temperature sensor 7. The communication module 6 is wirelessly connected to the cloud server.

[0043] The liquid cooling heat dissipation component 3 is connected to the central control module 5 and the temperature sensor 7.

[0044] The liquid cooling heat dissipation component 3 includes a liquid cooling module and a cabinet cooling component 39; both the liquid cooling module and the cabinet cooling component 39 are installed inside the control cabinet 1, and the liquid cooling module is connected to the cabinet cooling component 39.

[0045] The multiple installation and disassembly modules 2 of this utility model are set independently, and faulty modules can be replaced or repaired individually without disassembling the whole equipment, thus reducing maintenance complexity and downtime costs.

[0046] The liquid cooling module cools down the main heat-generating components inside the control cabinet 1, and the cabinet cooling assembly 39 cools down the entire interior of the control cabinet 1.

[0047] The central control module 5 is linked with the cloud server through the communication module 6 to monitor the temperature data of the liquid cooling module in real time, dynamically adjust the liquid cooling path and the start and stop of air cooling, and realize intelligent management of the heat dissipation system.

[0048] The closed-loop feedback mechanism of temperature sensor 7 and liquid cooling and air cooling components ensures that the inside of the cabinet is always maintained within a safe operating temperature range, extending the equipment life and improving charging stability.

[0049] like Figures 7-9 As shown, the installation and disassembly module 2 includes a fixing component 21 and a locking component 22. The fixing component 21 is connected to the locking component 22. The fixing component 21 is installed inside the control cabinet 1 and is connected to the liquid cooling module.

[0050] The fixing component 21 includes a storage box 211, a storage box 212, a charging module 213, and a first spring 215. The storage box 211 is fixedly installed inside the control cabinet 1. The interior of the storage box 211 is slidably connected to the storage box 212. The bottom left and right sides of the storage box 211 are provided with through slots 214. The first spring 215 is installed inside the two through slots 214 respectively. One end of the first spring 215 is fixedly connected to the rear end of the through slot 214, and the other end of the first spring 215 is fixedly connected to the lower end of the storage box 212. The bottom of the storage box 212 is provided with a slot 216. The rear side of the storage box 212 is provided with two openings 217 that are used to connect the wiring interface inside the control cabinet 1.

[0051] The interface of the charging module 213 and the interface inside the cabinet are both coated with a wear-resistant coating, such as gold plating.

[0052] The upper end of the storage box 211 is connected to the liquid cooling heat dissipation component 3, the storage box 211 is connected to the locking component 22, and the slot 216 is connected to the locking component 22.

[0053] The locking assembly 22 includes a fixed shaft 222, a locking plate 224, and a second spring 225. The storage box 211 has a slot 221 at its inner bottom. The left and right sides of the fixed shaft 222 are fixedly connected to the left and right side walls inside the slot 221, respectively. The lower end of the locking plate 224 is rotatably connected to the fixed shaft 222. The lower rear end of the locking plate 224 is fixedly connected to one end of the second spring 225. The other end of the second spring 225 is fixedly connected to the bottom of the slot 221. The latch 223 is fixedly connected to the front end of the locking plate 224. A locking block is fixedly installed on the upper rear end of the locking plate 224, and the locking block engages with the locking slot 216.

[0054] When installing the charging module 213, the installer puts the charging module 213 into the storage box 212, aligning the interface end on the charging module 213 with the opening 217 on the storage box 212. After the charging module 213 is placed, the installer pushes the storage box 212 inward, causing the storage box 212 to slide in the storage box 211 and compress the first spring 215. The storage box 212 moves the charging module 213 to the connection line interface inside the control cabinet 1, and the interface end of the charging module 213 is plugged into the connection line interface inside the control cabinet 1.

[0055] At the same time, the locking block at the upper rear end of the locking plate 224 moves to the slot 216. Under the action of the second spring 225, the locking block of the locking plate 224 engages with the slot 216 and locks, thereby fixing the storage box 212.

[0056] When inspecting the charging module 213, the maintenance personnel manually rotate the latch 223 upwards. The latch 223 drives the locking plate 224 to rotate around the fixed shaft 222. Based on the principle of leverage, the rear end of the locking plate 224 will compress the second spring 225, causing the latch block at the upper rear end of the locking plate 224 to disengage from the slot 216 and unlock. Then, the maintenance personnel manually pull the handle on the storage box 211 outwards, causing the charging module 213 to disengage from the connection line interface inside the control cabinet 1. The storage box 212 will then pop out of the storage box 211 under the action of the first spring 215, and the charging module 213 will pop out accordingly.

[0057] This invention enables convenient installation and removal of the charging module 213 without disassembling the entire device, thus reducing maintenance complexity and downtime costs.

[0058] like Figures 2-6As shown, the liquid cooling module includes a coolant storage container 31, a cooler 32, a pump 33, an inlet assembly 34, an outlet assembly 35, a cooling box 36, a fan 37, and a bend 38. The coolant storage container 31 and the cooler 32 are both fixedly installed at the bottom of the control cabinet 1. The internal pipes of the cooler 32 and the coolant storage container 31 are connected via a one-way valve. The pump 33 is fixedly installed at the top of the coolant storage container 31, with its inlet end connected to the top of the coolant storage container 31 and its outlet end connected to the inlet end. The components 34 are connected, the liquid inlet component 34 is connected to the cooling box 36 and the cabinet cooling component 39, the cooling box 36 is connected to the liquid outlet component 35, the cooling box 36 is provided in multiple and is fixedly installed on the upper end of multiple storage boxes 211, the temperature sensor 7 is fixedly installed inside the cooling box 36, the fan 37 is fixedly installed on the inner top of the cooling box 36, the bent pipe 38 is fixedly installed in the middle of the cooling box 36, the inlet end of the bent pipe 38 is connected to the liquid inlet component 34, the outlet end of the bent pipe 38 is connected to the liquid outlet component 35, and the cooling box 36 is connected to the cabinet cooling component 39.

[0059] The liquid inlet assembly 34 includes a first connecting pipe 341, a first diversion pipe 342, and an electric regulating valve 343. The lower end of the first connecting pipe 341 is fixedly connected to and communicates with the outlet end of the extraction pump 33. Multiple first diversion pipes 342 are provided at equal intervals and are fixedly connected to and communicate with the first connecting pipe 341 respectively. An electric regulating valve 343 is fixedly installed inside one end of the first diversion pipe 342. The other end of the first diversion pipe 342 passes through the cooling box 36 and is fixedly connected to and communicates with the inlet end of the bend pipe 38. The first connecting pipe 341 is connected to the cabinet cooling assembly 39.

[0060] The liquid outlet assembly 35 includes a second connecting pipe 351 and a second diversion pipe 352. The lower end of the second connecting pipe 351 is fixedly connected to and communicates with the inlet end of the cooler 32. Multiple second diversion pipes 352 are provided at equal intervals, and one end of each of the multiple second diversion pipes 352 is fixedly connected to and communicates with the second connecting pipe 351. The other end of each of the multiple second diversion pipes 352 passes through the cooling box 36 and is fixedly connected to and communicates with the outlet end of the bend pipe 38.

[0061] The control terminals of the cooler 32, the extraction pump 33, the fan 37, and the electric regulating valve 343 are all electrically connected to the central control module 5.

[0062] When this utility model is in use, when the charging pile 4 starts charging the electrical equipment, the corresponding charging module 213 starts working. When the temperature sensor 7 at the corresponding position detects that the temperature of the cooling box 36 has risen to a set threshold, the central control module 5 controls the extraction pump 33 to start. The extraction pump 33 extracts the coolant from the coolant storage container 31 into the first connecting pipe 341. The central control module 5 then controls the electric regulating valve 343 at the corresponding position to open, and coolant is introduced into the inside of the bend pipe 38. The fan 37 is turned on so that the temperature inside the cooling box 36 is cooled quickly and evenly, thereby cooling the charging module 213.

[0063] This invention can directly exchange heat with the cooling box 36 where the heat-generating core (charging module 213) is located, and accelerate local heat dissipation with the fan 37 to specifically reduce the temperature of high-heat-generating components.

[0064] Based on feedback from the temperature sensor 7, the central control module 5 can activate the electric regulating valve 343 to conduct the liquid cooling path only for the heating charging module 213, thus avoiding energy waste from global cooling and improving energy efficiency.

[0065] Example 2: In some embodiments, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 10 As shown, in a preferred embodiment of this utility model, the cabinet cooling assembly 39 includes an activated carbon filter 391, an air pump 392, an air inlet channel 393, an air outlet channel 394, and a solenoid valve 395. The activated carbon filter 391 and the air pump 392 are both fixedly installed on the outer end of the control cabinet 1. The activated carbon filter 391 is connected to the air inlet end of the air pump 392, and the air outlet end of the air pump 392 is fixedly connected to and connected to the air inlet channel 393. The other end of the air inlet channel 393 is fixedly connected to and connected to multiple cooling boxes 36. The left end of each of the multiple cooling boxes 36 is fixedly installed with an air outlet channel 394, and a solenoid valve 395 is fixedly installed inside each of the multiple air outlet channels 394.

[0066] Air pump 392 and solenoid valve 395 are both electrically connected to central control module 5.

[0067] When the temperature sensor 7 detects that the temperature inside the cooling box 36 has dropped to a preset range (such as between 30-45 degrees Celsius), the central control module 5 starts the air pump 392 and draws in the outside air into the air inlet channel 393 through the activated carbon filter 391.

[0068] like Figure 10 As shown, a heat exchanger 396 is fixedly installed in the air inlet channel 393, and the heat exchanger 396 is connected in parallel with the first connecting pipe 341.

[0069] If the outside air temperature is higher than the temperature of the cooling box 36: first, heat exchange is achieved through the air inlet channel 393, heat exchanger 396, and first connecting pipe 341 to pre-cool the air before it is sent into the cooling box 36.

[0070] In the cooling box 36, the temperature sensor 7 uploads real-time temperature information to the central control module 5. When the outside gas absorbs heat through the cooling box 36 and reaches a suitable temperature, the central control module 5 controls the solenoid valve 395 at the corresponding position to open, releasing the cooled gas into the control cabinet 1 to cool other components inside the control cabinet 1.

[0071] For example, when the temperature of the cooling box 36 drops from 60°C to 30°C, the liquid cooling system is paused, and the air pump 392 is started to draw in outside air (assuming the outside temperature is 34°C). The air flows through the air inlet channel 393 for pre-cooling, and then enters the cooling box 36 where the temperature is reduced to close to 30°C before being released into the cabinet to achieve cooling.

[0072] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
