[0040] This utility model proposes a liquid cooling component.

[0041] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the liquid cooling assembly is used to install in a charging socket. The liquid cooling assembly includes at least two connecting terminals 10, a terminal connecting block 20, at least two right-angle directional coolant inlets 30, and at least two cooling pipes 40. The two connecting terminals 10 are used to connect to the charging socket. The terminal connecting block 20 is connected to one side of the two connecting terminals 10. The connecting terminals 10 and the terminal connecting block 20 together form a flow cavity for coolant flow. Each right-angle directional coolant inlet 30 has a... The inlet 30a and outlet 30b are arranged at an angle. The other side of each of the connecting terminals 10 is connected to a right-angle turning coolant inlet 30 and communicates with the inlet 30a. Each of the cooling pipes 40 is connected to a right-angle turning cooling inlet and communicates with the outlet 30b. The cooling pipes 40 are used to introduce coolant. The flow cavity formed by the cooling pipes 40, the right-angle turning coolant inlets 30, the connecting terminals 10 and the terminal connecting blocks 20 is sequentially connected to form a cooling flow channel.

[0042] The connection terminal 10 here is a DC terminal, one of the core components of the liquid cooling assembly, used for electrical connection with the charging socket to achieve power transmission. During high-power charging, the connection terminal 10 generates a large amount of heat due to the current flow, thus requiring effective cooling measures to ensure its normal operation. The terminal connecting block 20 is used to connect two connection terminals 10 and forms a cavity inside. This cavity provides space for the flow of coolant, allowing the coolant to indirectly contact and exchange heat with the connection terminals 10, thereby removing the generated heat.

[0043] Cooling pipe 40 is a conduit used to transport coolant in the liquid cooling assembly. It connects to the right-angle turn coolant inlet 30, guiding the coolant into the liquid cooling assembly to participate in the cooling cycle. The material and design of cooling pipe 40 need to ensure good pressure resistance and corrosion resistance during coolant transport.

[0044] The operation of the liquid cooling assembly begins with the cooling pipe 40 introducing coolant into the cooling channel. The coolant first enters the right-angle turning coolant inlet 30, whose 90° turning design directs the coolant into the flow chamber formed by the connecting terminal 10 and the terminal connecting block 20. Within this flow chamber, the coolant absorbs heat from one connecting terminal 10, then flows through the terminal connecting block 20 into the other connecting terminal 10, absorbing heat from that terminal before finally exiting through another right-angle turning coolant inlet 30, completing one cooling cycle. During this process, all components work closely together to ensure efficient coolant circulation, continuously carrying away the heat generated by the connecting terminals 10 and guaranteeing the cooling effect of the liquid cooling assembly.

[0045] The right-angle directional coolant inlet 30 is a key component in the liquid cooling assembly used to change the direction of coolant flow. It has an inlet 30a and an outlet 30b arranged at an angle, allowing coolant to be introduced from one direction and output at a 90° angle to the other. This design helps optimize the spatial layout of the liquid cooling assembly, enabling more flexible installation within limited space.

[0046] This invention reduces the lateral dimension of the liquid cooling component by setting a right-angle turning coolant inlet 30 to connect the connecting terminal 10 and the liquid cooling pipe 40, thereby optimizing the spatial layout of the liquid cooling component and further reducing the lateral dimension of the charging socket, making it more flexible to install in application scenarios where the lateral dimension is limited.

[0047] To further improve the performance of the liquid cooling assembly, a temperature sensor can be added to monitor the temperature of the connection terminal 10 in real time. Data from the temperature sensor allows for dynamic adjustment of the coolant flow rate and velocity, ensuring that the connection terminal 10 is always within its optimal operating temperature range. This proactive temperature control further enhances the cooling efficiency and reliability of the liquid cooling assembly.

[0048] In one embodiment, please refer to Figure 1 and Figure 2Each connecting terminal 10 has a first cavity 10a, and the terminal connecting block 20 has a second cavity 20a communicating with the first cavity 10a; the liquid cooling assembly also includes a cooling block 50, one end of which passes through a first cavity 10a and through the second cavity 20a, and the other end of which passes through another first cavity 10a. The cooling block 50 is provided with an internal circuit 50a, which is connected to the inlet 30a of two right-angle turning coolant inlets 30.

[0049] The connecting terminal 10 is a key component of the liquid cooling assembly, used for electrical connection with the charging socket. It not only plays a crucial role in power transmission but also provides an initial channel—the first cavity 10a—for coolant circulation. The terminal connecting block 20 is an important component connecting the two connecting terminals 10. It forms a second cavity 20a internally, communicating with the first cavity 10a of the connecting terminal 10. This communicating cavity structure provides the necessary space for coolant circulation, allowing the coolant to form a complete loop throughout the liquid cooling assembly, thereby effectively removing the heat generated by the connecting terminal 10.

[0050] The cooling block 50 is a core component in the liquid cooling assembly used to enhance heat exchange efficiency. One end of it is located in the first cavity 10a of the connecting terminal 10, and the other end is located in the first cavity 10a of another connecting terminal 10. The cooling block 50 is provided with an internal circuit 50a. This design increases the contact area between the coolant and the cooling block 50, thereby improving heat exchange efficiency. At the same time, the internal circuit 50a also guides the flow of coolant, disperses the pressure direction during the flow process, and enhances the stability and reliability of the liquid cooling circuit.

[0051] The operation of the liquid cooling assembly begins with coolant entering the system through a right-angle turnaround coolant inlet 30. The coolant first flows into one end of the cooling block 50. Inside the cooling block 50, an internal circuit 50a guides the coolant flow, ensuring full contact with the cooling block 50 and absorbing the heat generated by the connection terminal 10. Subsequently, the coolant continues to flow within the cooling block 50. Finally, the coolant flows out through another right-angle turnaround coolant inlet 30 from the other end of the cooling block 50, completing one cooling cycle. During this process, all components work closely together to ensure efficient coolant circulation, continuously removing the heat generated by the connection terminal 10 and guaranteeing the cooling effect of the liquid cooling assembly.

[0052] This embodiment adds a cooling block 50 with an internal circuit 50a. The internal circuit 50a design not only increases the contact area between the coolant and the cooling block 50, improving heat exchange efficiency, but also disperses the pressure direction during the flow process by changing the coolant flow direction, thus enhancing the stability and reliability of the liquid cooling circuit. Furthermore, the tight fit between the cooling block 50 and the connecting terminal 10 and the terminal connecting block 20 ensures smooth circulation of the coolant, further improving the cooling performance of the liquid cooling assembly.

[0053] Furthermore, by optimizing the geometry of the cooling block 50, its contact area with the coolant can be increased, thereby improving heat exchange efficiency.

[0054] In one embodiment, please refer to Figure 3 , Figure 5 and Figure 6 The internal circuit 50a is an S-shaped circuit or a Z-shaped circuit.

[0055] Specifically, the cooling block 50 has spaced protrusions inside, and the sidewalls of these protrusions have gaps with the inner wall of the cooling block 50, dividing the internal circuit 50a into multiple continuous flow channels. Preferably, the internal circuit 50a is an S-shaped circuit or a Z-shaped circuit.

[0056] The internal circuit 50a is designed in an S-shape or a Z-shape. An S-shape circuit is a continuous, smooth curve structure that guides the coolant to flow more uniformly within the cooling block 50. A Z-shape circuit, on the other hand, is a zigzag structure that uses multiple turning points to create variations in the flow direction of the coolant within the cooling block 50. Both S-shape and Z-shape circuits aim to optimize the coolant flow path to improve cooling efficiency and component reliability.

[0057] On the other hand, the S-shaped and Z-shaped loop design significantly increases the contact area between the coolant and the cooling block 50. As the coolant flows through these loops, its contact time with the cooling block 50 is extended, thereby improving heat transfer efficiency. This design allows the coolant to more fully absorb the heat generated by the connection terminal 10, effectively reducing the temperature of the connection terminal 10. During high-power charging, this efficient heat exchange performance is crucial for ensuring the safety and stability of the charging socket.

[0058] In one embodiment, please refer to Figure 3 , Figure 5 and Figure 6 Cooling block 50 is an insulated cooling block 50.

[0059] Cooling block 50 plays a crucial role in heat exchange within the liquid cooling assembly, and its insulation properties are essential for the safety and reliability of the entire system. Cooling block 50 is made of an insulating material that not only has high thermal conductivity but also effectively isolates current, preventing energy leakage or short circuits. During high-power charging, a significant amount of heat is generated when current flows through connection terminals 10, and cooling block 50 needs to be in close contact with these electrical components to achieve efficient heat transfer.

[0060] The insulating coolant block 50 enables the liquid cooling assembly to be compatible with various coolant media, such as water or oil. Due to the insulating properties of the insulating coolant block 50, even the use of highly conductive coolants (such as water) will not affect electrical components. This compatibility allows the liquid cooling assembly to adapt to different application scenarios and cooling requirements, improving its versatility and flexibility.

[0061] In one embodiment, please refer to Figure 3 and Figure 4 The cavity wall of the second cavity 20a is provided with a plurality of protrusions 20b arranged at intervals, and each protrusion 20b extends along the extension direction of the second cavity 20a; the circumferential outer wall of the cooling block 50 is provided with a plurality of slots 50b, and each protrusion 20b is engaged in a slot 50b so that the cooling block 50 is engaged in the terminal connecting block 20.

[0062] In this embodiment, the second cavity 20a is an important space inside the terminal connection block 20, used to accommodate the cooling block 50 and provide a channel for coolant circulation. Multiple spaced protrusions 20b are provided on its cavity wall, extending along the extension direction of the second cavity 20a, providing precise positioning and stable support for the installation of the cooling block 50. The protrusions 20b are protruding portions on the cavity wall of the second cavity 20a, used to mate with the slots 50b on the cooling block 50. The design of the protrusions 20b ensures that the cooling block 50 can be accurately positioned during installation and remains stable during use, preventing displacement due to vibration or thermal expansion.

[0063] The cooling block 50 is the core component of the liquid cooling assembly, used to absorb the heat generated by the connecting terminal 10. Its circumferential outer wall is provided with multiple slots 50b, which engage with protrusions 20b on the wall of the second cavity 20a, allowing the cooling block 50 to be securely engaged with the terminal connecting block 20. The slots 50b are grooves on the circumferential outer wall of the cooling block 50, designed to engage with the protrusions 20b on the wall of the second cavity 20a. The design of the slots 50b ensures that the cooling block 50 is tightly embedded in the terminal connecting block 20, guaranteeing close contact and a stable mechanical connection between the two.

[0064] During the installation of the liquid cooling assembly, when the cooling block 50 is inserted into the second cavity 20a of the terminal connecting block 20, the protrusion 20b on the cavity wall of the second cavity 20a engages with the slot 50b on the outer circumferential wall of the cooling block 50, allowing the cooling block 50 to be accurately engaged with the terminal connecting block 20. This tight fit not only ensures the stable installation of the cooling block 50 but also provides a sealed channel for the circulation of coolant.

[0065] The tight fit between the protrusion 20b and the slot 50b ensures that the cooling block 50 will not shift during use, thus guaranteeing the stability of the cooling effect. At the same time, this design also enhances the overall structural strength of the liquid cooling assembly, enabling it to better adapt to complex installation environments and mechanical stresses. Furthermore, the stable installation of the cooling block 50 helps improve the heat dissipation efficiency of the liquid cooling assembly, ensuring that the connection terminal 10 maintains a low temperature during high-power charging, extending its service life.

[0066] In one embodiment, please refer to Figure 2 and Figure 3 The right-angle turning coolant inlet 30 includes an inlet body 31, an inlet pipe section 32, and an outlet pipe section 33. The inlet body 31 has an inner flow channel for coolant to flow through. The inlet pipe section 32 is connected to the inlet body 31 and communicates with the inner flow channel. The end of the inlet pipe section 32 away from the inlet body 31 is provided with an inlet port 30a, which extends into the first cavity 10a and abuts against the cooling block 50. The outlet pipe section 33 is connected to the end of the inlet body 31 away from the inlet pipe section 32 and communicates with the inner flow channel. The end of the outlet pipe section 33 away from the inlet body 31 is provided with an outlet port 30b, and the outlet pipe section 33 and the inlet pipe section 32 are arranged perpendicularly.

[0067] The inlet body 31 is the core component of the right-angle turning coolant inlet 30, and it has an internal flow channel for coolant circulation. The design of the internal flow channel ensures that the coolant can flow smoothly from the inlet pipe section 32 to the outlet pipe section 33, while changing the direction of the coolant flow to achieve a 90° turn. The material and structure of the inlet body 31 need to have good pressure resistance and corrosion resistance to ensure that there will be no leakage or damage during long-term use.

[0068] The inlet pipe section 32 is connected to the inlet body 31 and communicates with the inner flow channel. One end has an inlet port 30a for introducing coolant. The end of the inlet pipe section 32 furthest from the inlet body 31 extends into the first cavity 10a of the connecting terminal 10 and abuts against the cooling block 50. This design ensures that the coolant can flow directly into the cooling block 50 to begin the cooling process. The length and diameter of the inlet pipe section 32 need to be optimized according to actual application requirements to ensure that the coolant can enter the system at an appropriate flow rate and pressure.

[0069] The outlet pipe section 33 is connected to the end of the inlet body 31 furthest from the inlet pipe section 32 and communicates with the inner flow channel. One end of the outlet pipe section 33 has an outlet port 30b for discharging coolant. The outlet pipe section 33 and the inlet pipe section 32 are arranged perpendicularly, a design that allows the coolant to turn 90° after flowing out of the cooling block 50, completing a cooling cycle. The outlet pipe section 33 also needs to have good pressure resistance and corrosion resistance to ensure a stable discharge of coolant from the system.

[0070] The working process of the liquid cooling assembly: The coolant first enters the outlet pipe section 33 and flows into the inlet body 31 through the inner flow channel. Inside the inlet body 31, the coolant changes direction by turning 90° and enters the inlet pipe section 32. Subsequently, the coolant flows out through the inlet port 30a of the inlet pipe section 32 and enters the cooling block 50. Inside the cooling block 50, the coolant is in full contact with the cooling block 50, absorbing the heat generated by the connecting terminal 10. The coolant continues to flow, passing through the second cavity 20a of the terminal connecting block 20 and the first cavity 10a of the other connecting terminal 10, and finally flows out through another right-angle turn into the coolant inlet 30, completing a cooling cycle. During this process, the various components work closely together to ensure that the coolant can circulate efficiently, continuously carrying away the heat generated by the connecting terminal 10 and ensuring the cooling effect of the liquid cooling assembly.

[0071] The vertical arrangement of the inlet pipe section 32 and outlet pipe section 33 of the right-angle turning coolant inlet 30 optimizes the spatial layout of the liquid cooling assembly, allowing for more flexible installation within a limited space while reducing the lateral dimension occupied. Secondly, the inlet pipe section 32 extends into the first cavity 10a and abuts against the cooling block 50, ensuring that the coolant can flow directly into the cooling block 50, improving cooling efficiency. Furthermore, the vertical arrangement of the outlet pipe section 33 and the inlet pipe section 32 allows the coolant to turn 90° after flowing out of the cooling block 50, avoiding backflow and eddies during the flow process, further improving the cooling effect.

[0072] In one embodiment, please refer to Figure 2 and Figure 3 A groove is provided on the outer periphery of the mouthpiece body 31, and a first mouthpiece sealing ring 60 is installed in the groove. The first mouthpiece sealing ring 60 is used to abut against the inner wall of the charging socket.

[0073] The outer periphery of the inlet body 31 has a groove, and a first inlet sealing ring 60 is installed in the groove. The first inlet sealing ring 60 is used to abut against the inner wall of the charging socket to ensure that the coolant does not leak during flow. The sealing ring is usually made of rubber or silicone, which has good elasticity and aging resistance, and can maintain the sealing effect during long-term use.

[0074] Throughout the process, the tight contact between the first inlet sealing ring 60 and the inner wall of the charging socket effectively prevents coolant leakage during flow, ensuring stable system operation. This design not only improves the overall performance of the liquid cooling components but also enhances their adaptability to complex environments. Through optimized sealing design, the liquid cooling components can operate stably during high-power charging, effectively reducing the temperature of the charging socket and improving the safety and stability of the charging process.

[0075] Multiple grooves are provided on the peripheral outer wall of the inlet body 31, and multiple layers of sealing rings are installed to form a redundant sealing design. This design can further improve the sealing performance and ensure that the system can still maintain a seal even if a single sealing ring fails.

[0076] By optimizing the installation method of the sealing ring, such as using a 50b groove or threaded connection, it is made easier to install and maintain. At the same time, this design can improve the sealing ring's retention effect, preventing loosening or displacement during long-term use.

[0077] In one embodiment, please refer to Figure 2 and Figure 3 The right-angle turn-off coolant inlet 30 also includes a second inlet sealing ring 70, which is sleeved on the inlet pipe section 32 and elastically abuts against the inner wall of the cooling block.

[0078] The second inlet sealing ring 70 is fitted onto the inlet pipe section 32 and elastically abuts against the inner wall of the cooling block. The second inlet sealing ring 70 is typically made of rubber or silicone, possessing good elasticity and aging resistance, enabling it to maintain a sealing effect during prolonged use. This design ensures that the coolant does not leak during flow, further improving the system's sealing performance and reliability.

[0079] Multiple grooves are provided on the peripheral outer wall of the inlet body 31, and multiple layers of sealing rings are installed to form a redundant sealing design. This design can further improve the sealing performance and ensure that the system can still maintain a seal even if a single sealing ring fails.

[0080] In one embodiment, please refer to Figure 2 and Figure 3 The liquid cooling assembly also includes two spring tubes 80, each spring tube 80 being sleeved outside a cooling tube 40 to counteract external stress.

[0081] A Bourdon tube 80 is a hollow tubular structure made of elastic material, typically used to protect and support internal pipes while absorbing external shocks and vibrations. In liquid cooling assemblies, the Bourdon tube 80 is fitted over the cooling tube 40, primarily to counteract external stresses and protect the cooling tube 40 from damage. The Bourdon tube 80 is usually made of metal or high-performance plastic, possessing good elasticity and corrosion resistance.

[0082] Throughout the process, the Bourdon tube 80 is fitted over the cooling tube 40. The Bourdon tube 80 effectively absorbs external impacts and vibrations, protecting the cooling tube 40 from mechanical damage and extending its service life. Secondly, the elastic properties of the Bourdon tube 80 give the cooling tube 40 better adaptability during installation and use, enabling it to withstand different environmental conditions and mechanical stresses. Furthermore, the corrosion resistance of the Bourdon tube 80 ensures that it will not fail due to environmental factors during long-term use, further improving the overall performance of the liquid cooling assembly. Through this design, the liquid cooling assembly can operate stably during high-power charging, effectively reducing the temperature of the charging socket and improving the safety and stability of the charging process.

[0083] The Bourdon tube 80 utilizes higher-performance materials, such as nickel-titanium alloys or high-performance composite materials, which offer better elasticity and corrosion resistance, maintaining excellent performance even in harsher environments. Furthermore, by optimizing the structural design of the Bourdon tube 80, such as increasing its wall thickness or altering its helix angle, its shock and vibration resistance can be further improved. This design better protects the cooling tube 40, ensuring a stable delivery of coolant.

[0084] In one embodiment, please refer to Figure 2 and Figure 3 The liquid cooling assembly also includes two connecting sleeves 90, each connecting sleeve 90 being fitted onto the outside of the connection between the spring tube 80 and the right-angle turn-off coolant inlet 30 at the end away from the connecting terminal 10.

[0085] The connecting sleeve 90 is an important component of the liquid cooling assembly, used to connect the Bourdon tube 80 and the right-angle steerable coolant inlet 30. It is typically made of corrosion-resistant, high-strength materials, such as metals or high-performance plastics. The design of the connecting sleeve 90 ensures the sealing and stability of the coolant during flow, while providing mechanical support to protect the internal piping from external stresses.

[0086] First, the connecting sleeve 90 ensures the coolant's seal during flow, preventing leakage and thus improving system reliability. Second, the connecting sleeve 90 provides mechanical support for the spring tube 80 and the right-angle steerable coolant inlet 30, enhancing the overall structural strength of the assembly and enabling it to better withstand complex installation environments and mechanical stresses. Furthermore, the design of the connecting sleeve 90 makes the liquid cooling assembly easier to install and maintain, reducing maintenance costs and time.

[0087] This utility model also proposes a charging socket; please refer to [link / reference]. Figure 1 and Figure 3The charging socket includes a socket body and a liquid cooling assembly. The socket body has a mounting cavity. Two connecting terminals 10 of the liquid cooling assembly are inserted into the mounting cavity and electrically connected to the socket body. The specific structure of the liquid cooling assembly is as described in the above embodiments. Since this charging socket adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0088] This invention proposes a charging socket that cleverly combines a liquid cooling component with the socket body, achieving the dual advantages of efficient heat dissipation and stable charging. The socket body, as the basic structure of the entire charging socket, not only provides installation space for the liquid cooling component but also connects to the external circuitry, ensuring stable power transmission. Its internal mounting cavity provides precise positioning and stable support for the liquid cooling component. The liquid cooling component, as the core of the charging socket, consists of several carefully designed parts. Among them, the connecting terminal 10 is responsible for electrical connection with the charging device and is the key path for power transmission. The terminal connecting block 20 tightly connects two connecting terminals 10, forming a stable whole, while also providing a channel for coolant circulation. The right-angle turning coolant inlet 30, with its unique 90° turning design, optimizes the coolant flow path, enabling it to absorb and dissipate heat more efficiently. The cooling pipe 40 is responsible for delivering coolant to the interior of the liquid cooling component, while the spring tube 80 and connecting sleeve 90 provide additional protection and stability for the entire system.

[0089] When the charging socket is in operation, the connecting terminal 10 is inserted into the mounting cavity of the socket body and establishes an electrical connection with the socket body, ensuring that electrical energy can be smoothly transmitted to the charging device. Simultaneously, the liquid cooling assembly begins its heat dissipation function. Coolant enters the system through the cooling pipe 40, and after a 90° turn at the right-angle coolant inlet 30, flows into the connecting terminal 10. Inside the connecting terminal 10, the coolant is in full contact with the ceramic cooling block 50, absorbing the heat generated during high-power charging. Subsequently, the coolant continues to flow, along the internal circuit 50a of the cooling block 50, through the second cavity 20a formed by the terminal connecting block 20 and the first cavity 10a formed by the other connecting terminal 10, and finally flows out through another right-angle coolant inlet 30, completing a cooling cycle. Throughout the process, the spring tube 80 and the connecting sleeve 90 fit tightly together, protecting the cooling pipe 40 from external stress and ensuring stable coolant delivery.

[0090] This design allows the charging socket to maintain a low temperature during high-power charging, effectively improving charging safety and stability. The efficient heat dissipation capacity of the liquid cooling components ensures that the connection terminals 10 will not be damaged due to overheating, thereby extending the service life of the charging socket.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
