[0046] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0047] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0048] The following describes a split-type charging gun cooling device according to an embodiment of the present invention.

[0049] like Figures 1 to 4As shown, the present invention provides a split-type charging gun cooling device, which mainly includes a liquid storage tank 100, a centrifugal pump 200, a manifold assembly 700, a first adapter pipe 310, a second adapter pipe 320, a third adapter pipe 330, a fourth adapter pipe 340, and a cooling device 500.

[0050] The liquid storage tank 100 is used to contain and store the coolant (such as ethylene glycol aqueous solution, silicone oil, etc.) required for the entire equipment circulation.

[0051] Centrifugal pump 200 is located below liquid storage tank 100. This position utilizes gravity to help the pump draw liquid in. Its inlet end is connected to the outlet end of liquid storage tank 100 via a pipeline to provide power for the circulation of coolant.

[0052] The manifold assembly 700 is an integrated fluid distribution component with two key connectors: an outlet connector 710 and a return connector 720, which are used to connect the inlet and outlet ends of the charging gun, respectively. The outlet connector 710 is connected to the outlet end of the centrifugal pump 200 through a pipeline, thereby delivering pressurized coolant to the charging gun.

[0053] The first end of the first adapter pipe 310 is connected to the return connector 720 of the manifold assembly 700 for drawing back the high-temperature coolant carrying heat flowing from the charging gun.

[0054] The first end of the second adapter pipe 320 is connected to the inlet end of the liquid storage tank 100, and is used to send the cooled coolant back to the liquid storage tank 100.

[0055] The third adapter pipe 330 and the fourth adapter pipe 340 are key components connecting the basic circulation unit and the cooling unit. The first end of the third adapter pipe 330 is pluggably connected to the second end of the first adapter pipe 310; similarly, the first end of the fourth adapter pipe 340 is pluggably connected to the second end of the second adapter pipe 320.

[0056] The inlet of the cooling device 500 is connected to the second end of the third adapter pipe 330, and the outlet is connected to the second end of the fourth adapter pipe 340. Its core function is to effectively cool the high-temperature coolant flowing from the first adapter pipe 310.

[0057] This charging gun cooling device is divided into two independent modules: one is a liquid storage tank 100, a centrifugal pump 200, a manifold assembly 700, a first adapter pipe 310, and a second adapter pipe 320; the other is a third adapter pipe 330, a fourth adapter pipe 340, and a cooling device 500.

[0058] By placing the cooling unit 500 in a separate module that can be "plugged in" via adapter pipes, the equipment is modularized. When the cooling unit 500 needs maintenance, cleaning, or upgrades, the entire cooling unit can be removed simply by disconnecting the third adapter pipe 330 from the first adapter pipe 310, and disconnecting the second adapter pipe 320 from the fourth adapter pipe 340, without disassembling the entire complex piping system, greatly improving the maintainability and modularity of the equipment.

[0059] In some embodiments of this utility model, such as Figure 3 As shown, the charging gun cooling device also includes a first quick-connect assembly 410 and a second quick-connect assembly 420.

[0060] The first quick-connect assembly 410 includes two independent quick-connects, which are respectively fixedly installed at the second end of the first adapter tube 310 and the second adapter tube 320.

[0061] The second quick-connect assembly 420 also includes two independent quick-connects, which are fixedly installed at the first end of the third adapter tube 330 and the first end of the fourth adapter tube 340, respectively.

[0062] By inserting the male (or female) head of the second quick-connect assembly 420 into the corresponding female (or male) head of the first quick-connect assembly 410, a quick and sealed connection and separation between the third adapter tube 330 and the first adapter tube 310, and between the fourth adapter tube 340 and the second adapter tube 320 can be achieved.

[0063] The use of quick-connect couplings instead of traditional threaded or flanged connections makes the installation and disassembly of the cooling unit extremely simple and quick, requiring no tools and can be easily completed by ordinary personnel, further enhancing the modular advantages of the equipment and the user experience.

[0064] Furthermore, such as Figure 3 As shown, both connectors of the first quick-connect assembly 410 are female, while both connectors of the second quick-connect assembly 420 are male. This male-female pairing design is one of the standard forms of quick-connect connectors and can effectively prevent mis-insertion.

[0065] The standardized male and female connector definitions ensure the uniqueness and correctness of the connection, preventing users from mistakenly reversing the fluid path, thus guaranteeing the correct flow direction of the equipment and improving the reliability and safety of operation.

[0066] In some embodiments of this utility model, such as Figure 4 As shown, the cooling device 500 includes a microchannel radiator 520, the liquid inlet of which is connected to the second end of the third adapter 330, and the liquid outlet of which is connected to the second end of the fourth adapter 340.

[0067] The core of the cooling device 500 is the microchannel radiator 520. The inlet end of the microchannel radiator 520 is connected to the second end of the third adapter 330, and the outlet end is connected to the second end of the fourth adapter 340. The microchannel radiator 520 has a large number of flow channels with a size at the micrometer level inside, which greatly increases the heat dissipation area.

[0068] The microchannel radiator 520 features extremely high heat dissipation efficiency and a compact size, enabling it to quickly transfer heat from the coolant to the heat dissipation fins within a limited space. This achieves efficient cooling of the high-temperature coolant and meets the heat dissipation requirements of high-power charging.

[0069] Furthermore, such as Figure 1 and Figure 4 As shown, the cooling device 500 adds a fan 530 and a housing 510 to the microchannel heat sink 520.

[0070] The fan 530 is positioned directly opposite the microchannel heatsink 520. Its operating mode can be either blowing air onto the heatsink (blowing) or drawing air from the heatsink (drawing air). The purpose is to force airflow through the gaps between the heatsink fins, thereby significantly enhancing the convective heat transfer effect.

[0071] The housing 510 is used to house and fix the fan 530 and the microchannel heat sink 520, forming a complete cooling module unit, while also serving to guide airflow and protect internal components.

[0072] The addition of fan 530 enables active forced air cooling, significantly increasing the heat dissipation capacity of cooling device 500. The housing 510 makes cooling device 500 a standalone, complete, and easily transportable and installable functional module.

[0073] In some embodiments of this utility model, such as Figure 2 As shown, the charging gun cooling device is also equipped with a liquid level sensor 610. The liquid level sensor 610 extends into the interior of the tank 100 from the bottom, and its probe is located inside the tank to directly contact the coolant.

[0074] The liquid level sensor 610 can monitor the coolant volume in the storage tank 100 in real time. When the liquid level is too low, the equipment can issue an alarm or automatically stop the centrifugal pump 200 to prevent damage to the pump due to dry running, effectively protecting the core components of the equipment and improving the safety and intelligence level of the equipment.

[0075] In some embodiments of this utility model, such as Figure 2As shown, the internal structure of the branch block assembly 700 is specifically defined as comprising two independent first accommodating spaces and a second accommodating space. The first accommodating space serves as an outlet flow channel, connecting the outlet end of the centrifugal pump 200 and the outlet connector 710, flowing towards the charging gun. The second accommodating space serves as a return flow channel, connecting the first end of the first adapter pipe 310 and the return connector 720, flowing back towards the self-charging gun.

[0076] The inlet and outlet liquid channels are physically isolated inside the manifold block assembly 700, which avoids the heating of the low-temperature outlet liquid by the high-temperature return liquid (thermal short circuit), ensuring that the coolant sent to the charging gun is always at the lowest achievable temperature, thus improving the cooling efficiency of the equipment.

[0077] Furthermore, such as Figure 2 As shown, the charging gun cooling device also includes a first pressure sensor 730 and a second pressure sensor 740.

[0078] A first pressure sensor 730 is inserted into a first accommodating space to detect the pressure at the pump outlet and the charging gun inlet. A second pressure sensor 740 is inserted into a second accommodating space to detect the pressure at the charging gun outlet and the return liquid side.

[0079] By monitoring the pressure at both the inlet and outlet of the liquid, the equipment can calculate the pressure drop in the internal liquid circuit of the charging gun in real time. Abnormal changes in pressure drop can promptly indicate whether there is blockage, leakage, or bending in the pipeline, enabling real-time monitoring of the equipment's health status and fault early warning.

[0080] Furthermore, such as Figure 2 As shown, the charging gun cooling device also includes a first temperature sensor (not shown) and a second temperature sensor 750. The first temperature sensor is inserted into a first receiving space to detect a first temperature of the coolant within the first receiving space. The second temperature sensor 750 is inserted into a second receiving space to detect a second temperature of the coolant within the second receiving space.

[0081] A first temperature sensor is inserted into the first accommodating space to detect the temperature of the coolant supplied to the charging gun (i.e., the inlet temperature). A second temperature sensor 750 is inserted into the second accommodating space to detect the temperature of the coolant flowing back from the charging gun (i.e., the outlet temperature).

[0082] By combining inlet and outlet temperature data, the equipment can accurately calculate the actual heat dissipation of the charging gun, thereby more precisely controlling the heat dissipation intensity of the cooling device 500 (such as adjusting the fan speed 530). Simultaneously, the temperature data also provides direct monitoring of the charging gun's operating status; combined with pressure data, it enables a more comprehensive diagnosis of the equipment's condition.

[0083] In some embodiments of this utility model, such as Figure 2As shown, the charging gun cooling device also has a waterproof and breathable valve 620 installed on the top of the liquid storage tank 100.

[0084] The waterproof and breathable valve 620 allows air inside the liquid storage tank 100 to exchange with the outside atmosphere, balancing the pressure difference between the inside and outside of the tank caused by changes in coolant temperature and liquid level fluctuations, preventing positive or negative pressure, and increasing the service life of the liquid storage tank 100. At the same time, its waterproof properties prevent external water or impurities from entering the tank, ensuring long-term stable operation of the equipment.

[0085] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
