[0001] The invention relates to the technical field of component cooling improvement, and in particular to an immersion liquid cooling box for a charging module. Background Art

[0002] With the rapid growth of the new energy vehicle industry, the charging rate of electric vehicles is accelerating, and the power of charging facilities is also continuously increasing, resulting in increasingly severe challenges in the heat dissipation of charging piles. At present, the air-cooling heat dissipation technology commonly used in the market has been difficult to effectively cope with the growing demand for heat dissipation. In the face of this situation, liquid cooling technology has developed rapidly. For example, a liquid cooling box is disclosed in the prior art. This liquid cooling box includes a box body, a cooling pipe and a cover plate. The box body includes a first side wall, a second side wall and a bottom wall. The interior of the box body forms a cooling cavity for accommodating the element to be cooled. The box body is also provided with an opening. The bottom wall and the opening are opposite in a first direction, the first side wall and the second side wall are opposite in a second direction, and the first direction and the second direction are perpendicular. The cooling pipe is arranged in the cooling cavity. The cooling pipe includes a first pipe, a second pipe and a third pipe connected in series. The first pipe fits the first side wall, the second pipe fits the bottom wall, and the third pipe fits the third side wall. The end of the first pipe is exposed from the box body to form a liquid supply port, and the end of the third pipe is exposed from the box body to form a liquid outlet. The cover plate is sealed and connected to the box body at the opening. The liquid supply port and the liquid outlet port are used to connect the coolant supply device so that the coolant flows in the cooling pipe and the cooling element is cooled three-dimensionally.

[0003] However, the above-mentioned liquid cooling box cannot realize flexible configuration of the charging module while ensuring the cooling effect of the coolant, and lacks applicability to various application scenarios of the liquid cooling box. Summary of the invention

[0004] The purpose of the present invention is to provide a charging module immersion liquid cooling box to solve the problem that the liquid cooling box cannot realize the flexible configuration of the charging module while ensuring the cooling effect of the coolant, and lacks the applicability of the liquid cooling box in multiple application scenarios.

[0006] A liquid separation base is arranged at the bottom of the box body and is composed of a plurality of vertical lower baffles and horizontally arranged liquid cooling pipelines;

[0007] The liquid cooling pipeline is composed of a plurality of liquid distribution pipes arranged side by side, and the area where each liquid distribution pipe is located is divided into liquid cooling zones by the lower partition plate.

[0008] A mounting base is arranged above the liquid separation base and the upper surface of the mounting base is sealed and connected to the upper partition, and the mounting base is evenly distributed with a plurality of mounting grooves for mounting the charging module;

[0009] Wherein, a cover plate is movably connected to one side of the upper surface of the mounting groove, and the cover plate is closed when the charging module is not installed in the mounting groove to prevent the coolant from flowing through the mounting groove;

[0011] Liquid outlets, a plurality of which are provided above the mounting base and are used for outputting the cooling liquid flowing through the charging module;

[0012] A flow rate sensor is provided at each control valve and is used to collect the flow rate at each control valve;

[0013] The controller is used to switch the liquid inlet according to the flow rate at the two control valves in the liquid cooling zone, and to adjust the opening of the control valve at the liquid inlet end of each liquid distribution pipe according to the closing number of the cover plate.

[0014] As a preferred technical solution for the immersion liquid cooling box of the charging module, the controller obtains the flow rate at the two control valves collected by the flow rate sensor for any liquid cooling partition, and inputs the coolant through the liquid inlet opposite to the current liquid inlet position in response to the viscosity state of the coolant flow rate;

[0015] The sticky state satisfies that the flow rate difference between the two control valves is greater than a preset threshold value and lasts for a preset period of time.

[0016] As an optimal technical solution for the immersion liquid cooling box of the charging module, a sensing element for collecting the opening and closing of the cover is provided at the connection between the cover and the mounting groove, and the controller obtains the number of closures of the cover through data interaction with the sensing element.

[0017] As a preferred technical solution for the immersion liquid cooling box of the charging module, the controller adjusts the opening of the liquid inlet control valve according to the number of closures of the cover plate in response to a preset working state;

[0018] Among them, the preset working state satisfies that the number of closed cover plates is greater than the number of mounting slots in a single liquid cooling partition, and the opening of the liquid inlet end control valve is negatively correlated with the number of closed cover plates in the liquid cooling partition where it is located.

[0019] As the preferred technical solution for the immersion liquid cooling box of the charging module, each installation slot is hollowed out up and down, and each installation slot is provided with a power input interface and a power output interface.

[0023] As a preferred technical solution for the immersion liquid cooling box of the charging module, the number of the upper partitions is 3, and the number of the liquid outlets is 4, corresponding to the four areas formed by the upper partitions dividing the box body.

[0024] As an optimal technical solution for the immersion liquid cooling box of the charging module, there are four liquid inlets, which are arranged on both sides of the box body in pairs.

[0025] The beneficial effects of the present invention are:

[0026] The present invention provides a charging module immersion liquid cooling box. The charging module immersion liquid cooling box can ensure that the coolant flows evenly through each liquid cooling partition through the reasonable design of the upper partition and the lower partition, and the precise control of the liquid distribution pipe. Combined with the monitoring of the intelligent controller and the flow rate sensor, the dynamic adjustment of the coolant flow rate is realized, local area overheating or coolant retention is avoided, and the overall heat dissipation efficiency is improved.

[0027] In particular, the charging module immersion liquid cooling box of the present invention can adapt to different numbers of charging modules. When some charging modules are not installed, the system automatically controls the closure of the unused installation slot cover and correspondingly closes the control valve of the corresponding liquid cooling partition to ensure that the unused partition does not waste coolant and maximizes energy efficiency. At the same time, when multiple charging modules are working at the same time, the system can quickly adjust the flow path of the coolant. Since the charging module immersion liquid cooling box of the present invention can be flexibly configured according to the number of charging modules, whether it is used in electric vehicle charging stations, large data centers, or other scenarios that require high-power heat dissipation, the present invention can ensure that the most optimized heat dissipation solution is provided under different load conditions. By adjusting the opening of the control valve of the liquid cooling partition, the system can close unnecessary cooling paths under low load or idle conditions to ensure the effective use of resources. Ensure that the thermal management requirements of each module are met. It is suitable for the operation scenarios of various types of high-power charging equipment, with high flexibility and wide applicability.

[0028] In particular, the present invention adopts a two-way liquid inlet switching design, the main purpose of which is to deal with the problem of flow rate attenuation caused by viscosity during the flow of coolant. When the coolant flows in a constant direction, the viscosity will cause the flow rate to gradually decrease, which may cause uneven cooling between different charging modules. When the attenuation amplitude is too large or the coolant is blocked in certain areas, the flow rate can be effectively restored by switching the liquid inlet direction, and the coolant flow can be redistributed to ensure that each module is evenly and fully cooled. This design greatly improves the heat dissipation efficiency of the system and ensures the efficient circulation of the coolant, and is particularly suitable for complex cooling scenarios when multiple charging modules are working at the same time.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] like Figure 1-Figure 4 As shown, this embodiment provides a charging module immersion liquid cooling box, which includes: a box body 1, used to provide a liquid cooling space, and a plurality of vertical upper partitions 2 are evenly distributed above the inside of the box body 1;

[0040] The liquid separation base is arranged at the bottom of the box body 1 and is composed of a plurality of vertical lower partitions 3 and horizontally arranged liquid cooling pipelines;

[0041] The liquid cooling pipeline is composed of a plurality of liquid distribution pipes 4 arranged side by side. The area where each liquid distribution pipe 4 is located is divided into liquid cooling zones by a lower partition 3. Control valves 5 are provided at both ends of the liquid distribution pipe 4. A plurality of liquid distribution holes 6 are evenly distributed between the two control valves 5. Two adjacent liquid distribution pipes 6 can be connected or disconnected through the control valve 5. The lower partition 3 and the upper partition 2 are at the same horizontal position.

[0042] The mounting base is arranged above the liquid separation base and the upper surface of the mounting base is sealed and connected to the upper partition 2. The mounting base is evenly distributed with a number of mounting grooves 7 for mounting the charging module;

[0043] A cover plate 8 is movably connected to one side of the upper surface of the mounting groove 7, and the cover plate 8 is closed when the charging module is not installed in the mounting groove 7 to prevent the coolant from flowing through the mounting groove 7;

[0044] Liquid inlet 9, which is arranged on both sides of the box body 1 and is connected to the liquid separation base, is used for inputting the cooling liquid;

[0045] Liquid outlets 10, several of which are provided above the mounting base, for outputting the cooling liquid flowing through the charging module;

[0046] A flow rate sensor is provided at each control valve 5 and is used to collect the flow rate at each control valve 5;

[0047] The controller is used to switch the liquid inlet according to the flow rate at the two control valves in the liquid cooling zone, and to adjust the opening of the control valve at the liquid inlet end of each liquid distribution pipe according to the closing number of the cover plate.

[0048] In the above embodiment, through the reasonable design of the upper and lower partitions, and the precise control of the liquid distribution pipe, the liquid cooling box can ensure that the coolant flows evenly through each liquid cooling partition. Combined with the monitoring of the intelligent controller and the flow rate sensor, dynamic adjustment of the coolant flow rate is achieved to avoid overheating of local areas or coolant retention, thereby improving the overall heat dissipation efficiency. It can be adapted to different numbers of charging modules. The controller is composed of a logic component or a combination of logic components, which can be integrated into the liquid cooling box or set independently of the liquid cooling box.

[0049] When some charging modules are not installed, the system automatically controls the unused installation slot cover to close, and accordingly closes the control valve of the corresponding liquid cooling partition to ensure that the unused partition does not waste coolant and maximizes energy efficiency. At the same time, when multiple charging modules are working at the same time, the system can quickly adjust the flow path of the coolant to ensure that the thermal management requirements of each module are met. It is suitable for the operation scenarios of various high-power charging equipment and has high flexibility and wide applicability. Whether it is used in electric vehicle charging stations, large data centers, or other scenarios that require high-power heat dissipation, it can ensure the optimal heat dissipation solution under different load conditions. By adjusting the opening of the control valve of the liquid cooling partition, the system can close unnecessary cooling paths under low load or idle state to ensure the effective use of resources. And a two-way liquid inlet switching design is adopted, the main purpose of which is to deal with the problem of flow rate attenuation caused by viscosity during the flow of coolant. When the coolant flows in a constant direction, the viscosity will cause the flow rate to gradually decrease, which may cause uneven cooling between different charging modules. When the attenuation is too large or the coolant is blocked in certain areas, the flow rate can be effectively restored by switching the liquid inlet direction, redistributing the coolant flow to ensure that each module is evenly and fully cooled. This design greatly improves the heat dissipation efficiency of the system and ensures efficient circulation of the coolant, especially suitable for complex cooling scenarios when multiple charging modules are working at the same time.

[0050] In detail, the controller obtains the flow rate at the two control valves collected by the flow rate sensor for any liquid cooling zone, and inputs the coolant through the liquid inlet opposite to the current liquid inlet position in response to the viscosity state of the coolant flow rate;

[0051] The viscous state satisfies that the flow rate difference between the two control valves is greater than the preset threshold value for a preset time. It should be understood that when the liquid cooling box is working, for a single liquid distribution pipe, the control valve at the liquid inlet end is opened and the other control valve is closed.

[0052] In implementation, the threshold of the flow rate difference can be set according to the physical properties of the coolant (such as viscosity) and the specific needs of the system. The flow rate changes in each liquid cooling partition are monitored by the controller and the flow rate sensor, and when the viscosity state of the coolant flow rate is detected, the position of the liquid inlet is automatically switched to realize the intelligent regulation of the coolant. Control valves are provided at both ends of the liquid distribution pipeline in each liquid cooling partition, and flow rate sensors are installed at the control valves. The controller continuously receives real-time data from the flow rate sensor in each liquid cooling partition, and monitors the coolant flow rate at both ends of each liquid distribution pipeline respectively. The controller determines the flow rate difference at the two control valves according to the preset threshold. When the flow rate difference at the two adjacent control valves is greater than the preset flow rate threshold, and the flow rate difference lasts for a period of time (for example, 2 minutes), it is considered that the partition is in a coolant viscosity state. The viscous state usually means that the flow of the coolant is blocked, which may be because the coolant is retained in a certain part or the temperature of the local area rises, affecting the cooling effect. When the controller detects the viscous state, it automatically adjusts the position of the liquid inlet of the current liquid cooling partition. The controller closes the currently used liquid inlet, switches to the liquid inlet opposite to the current one, and re-injects coolant to ensure that the coolant flow returns to normal and optimizes the liquid cooling effect. After switching the liquid inlet, the controller continues to monitor the flow rate of the partition to ensure that the flow rate of the coolant returns to normal. If the flow rate difference gradually decreases, it means that the viscosity of the coolant has been released. This can effectively avoid the coolant from being retained in certain partitions and ensure the uniform flow of the coolant in the liquid cooling box, thereby improving the heat dissipation effect. Especially when multiple charging modules are running at the same time, the system can dynamically adjust the flow direction of the coolant to ensure that each module is within the appropriate temperature range, extend the service life of the module and improve the stability of the system.

[0053] In detail, a sensing element for collecting the opening and closing of the cover is provided at the connection between the cover and the mounting slot, and the controller obtains the number of closures of the cover through data interaction with the sensing element. The sensing element can use a Hall sensor or a photoelectric sensor to ensure that each opening or closing of the cover can be accurately identified. When the cover is in a closed state, the sensing element generates a closing signal, which is transmitted to the controller through a connecting line. When the cover is opened, the sensing element stops outputting signals, indicating that the cover is in an open state. This not only improves the intelligence of the cooling system, but also can flexibly adjust the allocation of cooling resources according to the usage of the module, avoid waste of resources, and improve the overall work efficiency of the system.

[0054] In detail, the controller adjusts the opening of the liquid inlet end control valve according to the closing amount of the cover plate in response to the preset working state;

[0055] Among them, the preset working state satisfies that the number of closed cover plates is greater than the number of mounting slots in a single liquid cooling partition, and the opening of the liquid inlet control valve is negatively correlated with the number of closed cover plates in the liquid cooling partition where it is located. Its purpose is to dynamically adjust the opening according to the number of working charging modules in each liquid cooling partition, so that the distribution of coolant can effectively adapt to the number of charging modules. Exemplarily, the opening of the liquid inlet control valve K=K0*(N1-N) / N0, where K0 is the maximum opening of the control valve, N1 is the number of mounting slots in the liquid cooling partition, N is the number of closed cover plates in the liquid cooling partition, and N0 is the total number of cover plates in the open state in the box.

[0056] Through intelligent adjustment of the control valve opening, this embodiment can flexibly control the supply of coolant according to the actual load of the system. The negative correlation control strategy ensures that the waste of coolant is reduced under low load or idle conditions, while sufficient coolant is supplied under high load conditions to maintain the efficient operation and heat dissipation performance of the system. In addition, the automatic adjustment function of the system reduces the need for manual intervention, improves the intelligence level of the entire liquid cooling system, and enhances its adaptability in complex working environments.

[0057] In detail, each installation slot is hollowed out from top to bottom, and each installation slot is provided with a power input interface and a power output interface. The interior of the installation base is a closed cavity, and the cavity inside the installation base is used to lay the transmission cable, and the transmission cable is sealed and connected to the power input interface and the power output interface. When the cover is opened, it fits with the upper partition, which can provide convenience for the installation of the charging module.

[0058] Continue reading Figure 4 As shown, in order to improve the sealing effect, a lock buckle 11 is rotatably connected to one side of the upper surface of the installation groove 7, and the lock buckle 11 can be rotated to overlap the cover plate 8 to fix the closed cover plate 8.

[0059] In detail, there are three upper partitions, and four liquid outlets are provided, corresponding to the four areas formed by the upper partitions dividing the box body. There are four liquid inlets, which are arranged on both sides of the box body opposite to each other. It can be understood that when the liquid cooling box is working, the liquid cooling modules should be centrally arranged. For example, when the number of installation slots in a single liquid cooling partition is 4 and the number of charging modules to be cooled is 3, the three charging modules can be installed adjacent to each other in the same liquid cooling partition. This layout method helps to optimize the cooling efficiency, reduce the waste of coolant in idle areas, and ensure that the cooling effect is concentrated on the charging modules in operation. This can not only ensure the centralized flow of coolant and give full play to the efficiency of the liquid cooling system, but also flexibly adapt to different charging module configuration requirements to maximize the utilization of resources.

[0060] Working principle: Align and plug the power input and output interfaces of several charging modules with the power input and output interfaces in the installation slot. The liquid inlet is connected to the liquid cooling system circulation pump, and the coolant enters the interior of the box from the liquid inlet. Limited by the structural design of the mounting base, all the coolant flows into the interior of the charging module from the lower end of the mounting slot. After the coolant fully absorbs the internal heat of the charging module, it flows out from the top of the charging module. Due to the existence of the mounting base, there are gaps between the charging modules. The coolant flows from this gap to the liquid outlet, which can produce a certain cooling effect on the outer shell of the charging module. The coolant flows out of the box from the liquid outlet for cooling, and the cooled liquid enters the liquid cooling box from the liquid inlet, thereby completing the cooling of the charging module.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
