Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and more specifically to an easy-to-maintain immersion liquid cooling and heating management system. Background Technology

[0002] With the booming development of the new energy vehicle industry, the market demand for charging piles, as a key supporting facility for electric vehicles, has exploded. High-power charging piles, with their advantage of fast charging speed, play an important role in meeting the rapid energy replenishment needs of electric vehicles. However, during high-power charging, the charging module generates a large amount of heat. If heat cannot be dissipated in a timely and efficient manner, it will seriously affect the performance and lifespan of the charging pile.

[0003] Traditional air-cooling methods exhibit numerous limitations when dealing with high-power charging stations. Due to air's low specific heat capacity, its ability to carry heat is relatively weak. When charging stations generate significant power and heat, air-cooling systems struggle to dissipate heat quickly and effectively, leading to excessively high internal temperatures in the charger. This results in decreased charger performance, increased failure rates, and a significantly shortened lifespan. Furthermore, air-cooling systems are highly susceptible to environmental factors. In complex environments such as underground mines, the large amounts of dust, moisture, and other impurities in the air easily adhere to fan blades, duct walls, and the surfaces of heat-generating components. This not only affects fan speed and airflow, reducing heat dissipation efficiency, but can also corrode and damage the electrical components of the charging station, further increasing the equipment's failure rate.

[0004] While immersion liquid cooling technology offers good heat dissipation, existing immersion liquid-cooled charging stations present several maintenance challenges. For example, some products have flawed structural designs, leading to high maintenance difficulty and costs for the charging modules. Some enclosures are open, which hinders the flow rate of the oil pump in the circulation pipes. To ensure the entire charging station is sealed, the dry cooler is placed on top and cannot be opened; therefore, if the charging module malfunctions, the entire charging station must be replaced, increasing maintenance costs and reducing its efficiency.

[0005] Therefore, how to provide an easy-to-maintain immersion liquid cooling and heating management system that has both high heat dissipation performance and ease of maintenance is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

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.

[0043] This utility model discloses an easy-to-maintain immersion liquid cooling and heating management system, such as... Figure 1 and Figure 2 As shown, it includes: a housing, a charging module 6, a heat dissipation module, and an intelligent control module;

[0044] The enclosure includes a fixed upper structure and a lower structure;

[0045] The charging module 6 is slidably connected to the upper structure;

[0046] The heat dissipation module is installed inside the lower structure;

[0047] The intelligent control module monitors the operating data of the charging module 6 and adjusts the parameters of the heat dissipation module according to the operating data of the charging module 6.

[0048] The upper structure is filled with coolant for heat dissipation of the charging module 6.

[0049] The heat dissipation module includes a liquid pump 2 and a cooling device;

[0050] The liquid pump 2 is installed at the bottom of the upper structure, and the coolant circulates through the liquid pump 2. The refrigeration device dissipates heat from the coolant.

[0051] The intelligent control module enables intelligent control of the heat dissipation module. It can automatically adjust parameters according to the actual working status of the charging module 6, avoiding unnecessary energy consumption. This energy-saving buffer design reduces the operating cost of the charging pile while ensuring heat dissipation, which is in line with the development trend of energy conservation and environmental protection.

[0052] Specifically, the enclosure is a tank enclosure 4; the height of the tank enclosure 4 is set to 1.2 meters.

[0053] This embodiment of the utility model uses a tank housing 4 of a specific height, which is conducive to the operation of maintenance personnel and facilitates maintenance of the charging module 6. This height design is different from the height of other conventional housings.

[0054] Specifically, the refrigeration device includes a dry cooler 3 and a fan;

[0055] The liquid pump 2 is connected to the inlet of the dry cooler 3 via a pipeline;

[0056] The dry cooler 3 is installed below the upper structure, and the dry cooler 3 has multiple heat exchange channels inside;

[0057] The fan is installed on one side of the dry cooler 3, the air outlet is located on the other side of the dry cooler 3, and the air inlet is located on both sides of the dry cooler 3.

[0058] This embodiment of the invention employs a coolant circulation cooling method. A liquid pump 2 circulates the coolant, carrying away heat from the charging module 6. The heat is then dissipated through a dry cooler 3 and a fan, forming a complete coolant circulation cooling module. This immersion liquid cooling method offers better cooling performance than traditional air cooling, effectively ensuring the stability of the charging module 6 during high-power operation.

[0059] Furthermore, the specific air duct design of this utility model embodiment: the air duct design that protects air intake on both sides and air exhaust on one side can ensure that the air is in full contact with the dry cooler 3, improve heat dissipation efficiency, and is an important component of the heat dissipation module.

The sealed top cover 5 can prevent coolant leakage and ensure that the coolant circulates normally in the tank. At the same time, the openable design makes it easy for maintenance personnel to perform plug-and-play maintenance operations on the charging module 6.

[0064] Specifically, a power connector array is provided within the upper structure;

[0070] The plug corresponds to the power connector 8;

[0071] The plug is inserted into the power connector 8 via slide 7.

[0072] The tank housing 4 is designed with a power connector array and a corresponding slide rail 7 structure. This design allows the charging module 6 to be directly plugged in and unplugged through the slide rail 7, which greatly improves the maintainability of the charging module 6 and contrasts sharply with the traditional complex wiring connection and fixing methods.

[0073] The design of using a slide rail 7 and a power connector array to enable direct plug-in / plug-out of the charging module 6 is a major highlight of this embodiment. Maintenance of the charging module 6 in traditional charging piles often requires a complex disassembly and installation process.

[0075] Specifically, the charging module 6 comprises 10 units, arranged in a 2x5 array or a 1x10 array. This flexible layout can meet the diverse power and space requirements of charging piles in different application scenarios, improving the system's adaptability and practicality.

[0076] Specifically, a temperature sensor is mounted on the surface of the charging module 6; a power monitoring module is installed in the charging circuit of the charging module 6.

[0078] The application of the CDU control board enables intelligent control of the fan speed and the flow rate of the liquid pump 2, achieving the function of energy-saving buffer design. By automatically adjusting relevant parameters according to the real-time temperature and power requirements of the charging module 6, energy saving is achieved, improving the energy utilization efficiency of the system.

[0079] In one specific embodiment of this utility model, a 400KW immersion liquid-cooled charging pile has a core component of a tank housing 4. The tank housing 4 is positioned at a height of 1.2 meters for easy operation by maintenance personnel. The tank housing 4 is filled with highly insulating coolant for heat dissipation of the charging module 6. The housing is equipped with a sealed top cover 5, which can be opened for easy maintenance. Immersion liquid cooling technology is employed, and the specific structure is as follows... Figure 1 and Figure 2 As shown:

[0080] 1) Overall Structure: The main body of the 400KW immersion liquid-cooled charging pile consists of a tank housing 4, a sealed top cover 5, a charging module 6, a power connector array, a slide rail 7, a dry cooler 3, and a fan. The tank housing 4 is a cuboid structure with a height of 1.2 meters.

The sealed top cover 5 is connected to the tank housing 4 via hinges. A rubber sealing ring is provided on the edge of the top cover to ensure a tight seal when the cover is closed. The fan is fixed at the fan port 1.

[0081] 2) such as Figure 3 As shown, the charging module 6 installation structure is as follows: A power connector array is fixedly mounted on one side of the inner wall of the tank housing 4, with each power connector 8 connected to an external circuit. A slide rail 7 is installed parallel to the bottom of the power connector array. The length and width of the slide rail 7 match the dimensions of the charging module 6, ensuring that the charging module 6 can slide smoothly on the slide rail 7. A plug corresponding to the power connector 8 is provided on the back of the charging module 6. When the charging module 6 is inserted along the slide rail 7, the plug can accurately connect with the power connector 8.

[0082] This embodiment of the invention incorporates a power connector array within the tank housing 4. Each charging module 6 connects to the power connector array via a slide rail 7, enabling direct plug-and-play operation. The charging modules 6 are 40kW in size and can be arranged in either a 2x5 array or a 1x10 array to meet different power requirements. This design allows maintenance personnel to directly plug and unplug the charging modules 6 for maintenance without disassembling complex wiring and structures, significantly improving maintenance efficiency.

[0083] 3) such as Figure 1 As shown, the heat dissipation module consists of a liquid pump 2 installed in the lower half of the tank and connected to the inlet of the dry cooler 3 via a pipe. The dry cooler 3 is a plate heat exchanger, also installed in the lower half of the tank, and contains multiple heat exchange channels. The coolant flows within these channels, exchanging heat with the outside air. A fan is installed on one side of the dry cooler 3, with air inlets on both sides and air outlets on the other side. When the fan starts, outside air enters the air duct through the inlets on both sides, flows over the surface of the dry cooler 3, absorbs the heat dissipated by the coolant, and is then discharged through the outlet.

[0084] The coolant circulates through the liquid pump 2, carrying away the heat generated by the charging module 6. A cooler 3 and a fan are located below the tank housing 4 to dissipate heat from the coolant. The airflow uses a two-sided intake and one-sided exhaust design to ensure sufficient air contact with the cooler 3, improving heat dissipation.

[0085] It also includes a filter device installed in the coolant circulation loop. The filter device is a Y-type filter that is directly installed in the pipeline loop for coolant cleaning technology.

[0086] 4) Intelligent Control: The CDU control board is installed inside the control panel of the charging pile and connects to the temperature sensor, power monitoring module, fan, and liquid pump 2 via data cables. The temperature sensor is installed on the surface of the charging module 6 to monitor its temperature in real time; the power monitoring module is installed in the charging circuit to monitor its power in real time. Based on the data fed back from the temperature sensor and power monitoring module, the CDU control board adjusts the fan speed and the flow rate of the liquid pump 2 through the control circuit.

[0087] The fan speed and pump flow rate can be controlled via the CDU control board. The CDU control board can automatically adjust the fan speed and pump flow rate based on the real-time temperature and power requirements of the charging module 6, achieving an energy-saving buffer design that reduces energy consumption while ensuring heat dissipation.

[0088] This utility model embodiment adopts immersion liquid cooling technology, which has higher heat dissipation efficiency compared with traditional heat dissipation methods. It can dissipate the heat generated by the charging pile during operation in a timely and effective manner, ensuring the stability and reliability of the charging pile when operating at high power.
