Description

Technical Field

[0001] The present application relates to the technical field of cooling water pipes for electric vehicles, and in particular to a series of cooling water pipes. Background Art

[0002] In the field of new energy vehicles, especially pure electric vehicles, key components such as batteries, motors, electronic control units, and charging units need to operate within an appropriate temperature range to ensure the normal operation and performance of the vehicle. The cooling pipe system removes excess heat from the working parts through circulating cooling water, and dissipates the heat through heat dissipation equipment such as radiators and battery coolers, thereby maintaining a suitable operating temperature.

[0003] In the related art, the cooling pipe system usually includes a plurality of pipe bodies, each of which is respectively connected to an expansion water tank, a cooling water pump, a battery cooler and other components to ensure smooth circulation of cooling water.

[0004] With respect to the above-mentioned related technologies, the distribution of the single pipe bodies is relatively scattered, and while ensuring the smooth circulation of cooling water, it is also necessary to reduce the installation space occupied by the cooling pipe system. Therefore, it is necessary to provide a cooling water pipe that makes the layout of the single pipe bodies compact. Utility Model Content

[0005] In order to improve the problem of low compactness between pipe bodies and reduce the overall space occupied by the cooling pipe system, the present application provides a series of cooling water pipes.

[0006] The present application provides a series of cooling water pipes adopting the following technical solutions:

[0007] A series of cooling water pipes includes a first cooling pipe, a second cooling pipe, a third cooling pipe and a fourth cooling pipe which are fixedly connected in sequence between side walls, and both ends of the first cooling pipe, the second cooling pipe, the third cooling pipe and the fourth cooling pipe are respectively provided with connecting ends for connecting with other components.

[0008] By adopting the above technical solution, compared with the solution of scattered distribution of a single pipe body, the side walls of the first cooling pipe, the second cooling pipe, the third cooling pipe and the fourth cooling pipe are fixedly connected in sequence, thereby improving the compactness between the pipe bodies, not only reducing the installation space required for the cooling pipe system, but also making the entire system more neat and orderly, which is conducive to the rational use of the interior space of the vehicle. The pipe bodies are arranged in a row and closely connected, which helps to achieve a more uniform heat distribution and further improve the cooling effect. The row of cooling water pipes is pre-formed into a whole by multiple pipe bodies, which reduces the steps and difficulty of on-site installation and facilitates subsequent maintenance and repair work.

[0009] Further, the connecting end includes a left first end and a right first end provided at both ends of the first cooling pipe, a left second end and a right second end provided at both ends of the second cooling pipe, a left third end provided at the end of the third cooling pipe, and a right fourth end provided at the end of the fourth cooling pipe;

[0010] The third cooling tube is provided with a third tube body socket for installing other components at the end away from the left third terminal, and the fourth cooling tube is provided with a fourth tube body socket for installing other components at the end away from the right fourth terminal.

[0011] By adopting the above technical solution, a dedicated connection terminal (such as the left first terminal, the right first terminal, the left second terminal, the right second terminal, the left third terminal and the right fourth terminal) is provided for each cooling pipe to ensure stable and reliable connection between the cooling water pipe and other components, thereby improving the convenience of installation and the overall performance of the system. The third cooling pipe and the fourth cooling pipe are respectively provided with a third pipe body socket and a fourth pipe body socket, providing the possibility of further expansion of the cooling system. When it is necessary to add additional cooling pipes or connect other cooling components, the sockets can be used for connection without making large-scale changes to the entire cooling pipe system, thereby improving the flexibility and scalability of the system.

[0012] Furthermore, a 135° two-way joint is fixedly connected to the third pipe body socket.

[0013] By adopting the above technical solution, the 135° two-way joint allows the cooling water to turn at an angle of 135 degrees when connected, providing more flexible fluid guidance capabilities. The cooling water can be directed to different directions or connected to other cooling components according to the actual layout requirements of the cooling system, thereby improving the flexibility and adaptability of the cooling system. While providing sufficient turning angles, the 135° two-way joint can effectively reduce space occupancy, which is particularly important for new energy vehicles with limited interior space, and helps to achieve a more complex cooling system layout within a limited space.

[0014] Furthermore, a 90° two-way joint is fixedly connected to the fourth tube body socket, and the 90° two-way joint is bent toward the left third end away from the end connected to the socket.

[0015] By adopting the above technical solution, the 90° two-way connector provides a 90-degree turning angle, allowing the cooling water to achieve a right-angle turn when connected, increasing the flexibility of the connection, and can guide the cooling water to different directions according to the actual layout requirements, providing additional degrees of freedom to adapt to complex cooling system layouts. The 90° two-way connector is bent to the left third end to avoid interference with other components or systems, allowing the cooling pipe system to be arranged more compactly inside the vehicle, helping to improve overall space utilization.

[0016] Furthermore, the row of cooling water pipes also includes a first connecting piece and a second connecting piece for connecting with other components;

[0017] A reinforcing plate is integrally connected between adjacent side walls of the second cooling tube and the third cooling tube, the first connecting member is disposed on the reinforcing plate, and the first connecting member is located between the left second end and the left third end;

[0018] The first cooling pipe is integrally connected with a connecting plate on the outer wall of the first cooling pipe at the side where the right first end is provided, and the second connecting member is provided on the connecting plate.

[0019] By adopting the above technical solution, a reinforcing plate is integrally connected between the adjacent side walls of the second cooling pipe and the third cooling pipe, thereby enhancing the structural strength between the second cooling pipe and the third cooling pipe, preventing the cooling pipe from being deformed or damaged when subjected to external pressure or vibration, and improving the stability and durability of the entire cooling pipe system. The first connecting piece is arranged on the reinforcing plate, between the left second terminal and the left third terminal, providing an additional connection point for the cooling system, facilitating the connection of the row of cooling water pipes with other components such as the radiator and the battery cooler, and increasing the flexibility and scalability of the system. The connecting plate on the first cooling pipe and the second connecting piece further optimize the layout of the cooling pipe system, reduce additional connecting components and pipe length, help save installation space and improve the integration of the system.

[0020] Furthermore, a first through hole for the first connecting member to pass through is formed on the reinforcing plate, and a first sliding groove connected with the first through hole and for the first connecting member to be inserted is formed on the reinforcing plate at a position adjacent to the first through hole.

[0021] By adopting the above technical solution, the first through hole is used for the first connecting member to pass through, and the first slide groove enables the first connecting member to slide into the through hole along the slide groove and be clamped in a fixed position. The installation method is quick and convenient, and is easy for subsequent disassembly and maintenance.

[0022] Furthermore, a second through hole for the second connecting member to pass through is formed on the connecting plate, and a second sliding groove connected with the second through hole and for the second connecting member to be inserted is formed on the connecting plate at a position adjacent to the second through hole.

[0023] By adopting the above technical solution, the second connector slides into the second through hole along the second slide groove and is fixed by clamping, so that the installation of the second connector is more convenient. The second slide groove provides a fixing point for the second connector, so that the second connector can maintain a more stable state after being clamped, which helps to reduce the loosening or falling off of the connection caused by vibration or impact, and enhances the overall stability of the cooling pipeline system.

[0024] Furthermore, a first reinforcing rib is provided between the first cooling tube and the second cooling tube, a second reinforcing rib is provided between the second cooling tube and the third cooling tube on the side away from the reinforcing plate, and a third reinforcing rib is provided between the third cooling tube and the fourth cooling tube.

[0025] By adopting the above technical solution, the reinforcing ribs enhance the structural strength between the cooling pipes. The reinforcing ribs can withstand various stresses and vibrations from the vehicle operation process, making the entire row of cooling water pipes more durable and preventing the cooling pipes from deformation or damage, thereby extending the service life of the cooling system. While enhancing the structural strength, the reinforcing ribs can also act as heat sinks to a certain extent, increasing the contact area between the cooling pipes, which is beneficial to the transfer and dissipation of heat, thereby improving the heat dissipation performance of the cooling system.

[0026] Further, it comprises a left row of pipes and a right row of pipes formed integrally by blow molding, the left row of pipes is provided with a left connecting seat for connecting with the right row of pipes, and the right row of pipes is provided with a right connecting seat for fixedly connecting with the left connecting seat on a side close to the left row of pipes;

[0027] The first cooling tube, the second cooling tube, the third cooling tube and the fourth cooling tube on the left row of tubes correspond to the first cooling tube, the second cooling tube, the third cooling tube and the fourth cooling tube on the right row of tubes one by one and are interconnected.

[0028] By adopting the above technical solution, the blow-molded cooling pipe has a higher structural strength, can better withstand various stresses and vibrations from the operation of the vehicle, helps to reduce the deformation and damage risks of the cooling pipe, and improves the stability and reliability of the cooling system. The corresponding cooling pipes on the left and right rows of pipes are interconnected through the connecting seat to ensure that the cooling water can flow smoothly throughout the system. The setting method of the left connecting seat and the right connecting seat simplifies the connection structure between the left and right rows of pipes. By fixing the two connecting seats, a tight connection between the left and right rows of pipes can be achieved without the need for additional connectors or seals, thereby reducing manufacturing costs and improving the reliability of the connection.

[0029] Furthermore, the left connecting seat is provided with a snap-fitting ridge that matches the diameter of each cooling tube, and the right connecting seat is provided with a snap-fitting groove that matches the snap-fitting ridge.

[0030] By adopting the above technical solution, the snap-in ribs and snap-in grooves ensure the precise alignment of the left and right rows of pipes when connected, and the diameter of each cooling pipe has a corresponding snap-in rib to match, which effectively prevents misalignment or offset during the connection process, and improves the accuracy and reliability of the connection. The snap-in ribs and snap-in grooves are tightly matched to form an effective seal at the connection to prevent leakage of cooling water during the flow process, ensuring the normal operation and efficient heat dissipation of the cooling system. The snap-in ribs and snap-in grooves ensure the precise alignment of the left and right rows of pipes when connected, and the diameter of each cooling pipe has a corresponding snap-in rib to match, which effectively prevents misalignment or offset during the connection process, and improves the accuracy and reliability of the connection. The snap-in ribs and snap-in grooves are tightly matched to form an effective seal at the connection to prevent leakage of cooling water during the flow process, ensuring the normal operation and efficient heat dissipation of the cooling system.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1. By sequentially fixing and connecting the side walls of the first cooling pipe, the second cooling pipe, the third cooling pipe and the fourth cooling pipe, a row of cooling water pipes is formed, which significantly improves the compactness between the pipe bodies, not only reduces the installation space required for the cooling pipe system, but also makes the entire system more neat and orderly, which is conducive to the rational use of the interior space of the vehicle. The pipe bodies arranged in a row and closely connected help to achieve a more uniform heat distribution and further improve the cooling effect;

[0033] 2. Provide a dedicated connection end for each cooling pipe to ensure a stable and reliable connection between the cooling water pipe and other components, thereby improving the convenience of installation and the overall performance of the system. The third and fourth cooling pipes are respectively provided with a third tube body socket and a fourth tube body socket, providing the possibility of further expansion of the cooling system. When it is necessary to add additional cooling pipes or connect other cooling components, the sockets can be used for connection without making large-scale changes to the entire cooling pipe system, thereby improving the flexibility and scalability of the system. The setting of the 135° two-way connector and the 90° two-way connector provides flexible fluid guiding capabilities, which can guide the cooling water to different directions according to the actual layout requirements, increasing the flexibility of the connection;
