Technical Field

[0001] The present invention relates to the technical field of manufacturing fluid medium conveying devices, and particularly relates to a flow channel plate and a flow splitting assembly. Background Art

[0002] Fluid medium is a special material widely used in professional fields such as hydraulics, pneumatics, and refrigeration. For example, hydraulic oil in hydraulic technology, high-pressure air in pneumatic technology, or refrigerant and coolant in refrigeration technology.

[0003] In the prior art, the above-mentioned fluid medium is usually conveyed by various metric pipes, which has the advantages of being easily obtainable, low cost, and extremely high interchangeability, bringing convenience to the conveyance of various fluid media in industry and promoting the application of fluid media in different fields.

[0004] However, with the continuous development of technology, higher requirements are put forward for the volume of various products in industries such as refrigeration and hydraulics. For example, in the automotive industry, it is required that vehicle air conditioners be made small enough, and the corresponding functions not only cannot be reduced, but need to be increased instead.

[0005] Obviously, it is extremely wasteful of space to use various metric pipelines to convey fluid medium, and it can no longer adapt to the current situation at all.

[0006] Therefore, how to improve the fluid medium conveying device and minimize the volume as much as possible while ensuring the conveying efficiency has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

Detailed implementation mode

[0055] Embodiment

[0056] As Figures 1 to 7 As shown, the flow channel plate includes multiple pipelines 1 for transporting fluid media; it is characterized in that the multiple pipelines 1 are arranged in parallel with each other, and one end of each is arranged on the same reference plane;

[0057] The reference plane is used to connect with the control device 2, and through the control device 2, the connection or disconnection between each pipeline 1 and other pipelines 1 is controlled;

[0058] An external connection pipe 4 and / or an internal connection pipe 5 are provided at the other end and / or the pipe wall near the other end of each pipeline 1;

[0059] Each external connection pipe 4 extends outward along the periphery of the reference plane for connecting with functional components that need to access fluid media, and there is only one elbow structure between each external connection pipe 4 and the corresponding pipeline 1;

[0060] Each internal connection pipe 5 is used for connecting more than two pipelines 1, and is coaxially arranged with the external connection pipe of the corresponding pipeline 1.

[0061] The present invention integrates the flow channel plate structure in the case of including multiple pipelines 1, integrates the connection ends between all pipelines 1 and the control device 2 with a valve core on a reference plane, and connects with the control device 2 through a flange docking structure;

[0062] It is also convenient to arrange the functional components that need to access fluid media around the reference plane of the flow channel plate so as to connect with each pipeline 1, which not only makes more full use of the space, but also makes it more convenient to maintain various functional components and the control device.

[0063] There is only one elbow structure between each external connection pipe 4 and the corresponding pipeline 1 in the present invention, and each internal connection pipe 5 is coaxially arranged with the external connection pipe of the corresponding pipeline 1, so the flow channel plate of the present application can be directly injection molded with one part.

[0064] Compared with the flow channel plate in the prior art that needs to be synthesized by more than 2 plates and requires processes such as hot plate welding, infrared welding or laser welding, or a form with a sealing gasket in the middle, there is no longer a need for a sealing structure and process.

[0065] There is no leakage risk between all the pipelines in the integrated injection-molded runner plate. There will be no internal leakage between pipelines. In the prior art, the runner plate that needs to be composed of more than 2 plates has unstable processes, unreliable welding or sealing. After long-term use, the welded joints are prone to separation, resulting in the risk of internal leakage and even the failure of the entire module equipped with the runner plate.

[0066] In some embodiments, all the pipelines 1 are arranged perpendicular to the reference plane;

[0067] Each functional component is fixed on the side surface of the columnar structure formed by multiple pipelines 1.

[0071] The pipeline 1 corresponding to the first column of the third row of the rectangular array serves as the second runner 7;

[0072] The first runner 6 and the second runner 7 form the first flow circuit;

[0073] The first flow circuit is used to connect with the first functional component;

[0074] Both the first runner 6 and the second runner 7 are connected to the first functional component through the corresponding external connection pipes 4 and are connected through the internal connection pipes 5;

[0075] The external connection pipes 4 of both the first runner 6 and the second runner 7 extend outward along the vertical direction of the third row of the connection point array, and the distance between the external connection pipe 4 of the second runner 7 and the reference plane is less than the distance between the external connection pipe 4 of the first runner 6 and the reference plane.

[0076] As Figure 6 shown, in some embodiments, the pipeline 1 corresponding to the second column of the second row of the rectangular array serves as the third runner 8;

[0077] The pipeline 1 corresponding to the second column of the third row of the rectangular array serves as the fourth runner 9;

[0078] The third runner 8 and the fourth runner 9 form the second flow circuit;

[0079] The second flow circuit is used to connect with the second functional component;

[0080] The third flow channel 8 extends outward along the vertical direction of the first column of the rectangular array from the outside of the other end of the first flow channel 6 through the corresponding external connection pipe 4;

[0081] The fourth flow channel 9 extends outward along the vertical direction of the third row of the rectangular array through the corresponding external connection pipe 4.

[0082] As Figure 5 and Figure 7 shown, in some embodiments, the pipeline 1 corresponding to the third column of the third row of the rectangular array serves as the fifth flow channel 10;

[0083] The pipeline 1 corresponding to the second column of the first row of the rectangular array serves as the sixth flow channel 11;

[0084] The fifth flow channel 10 and the sixth flow channel 11 form a third flow circuit;

[0085] The third flow circuit is used to connect with the third functional component;

[0086] Both the fifth flow channel 10 and the sixth flow channel 11 are connected to the third functional component through the external connection pipe 4 extending outward along the vertical direction of the first row of the rectangular array.

[0087] As Figure 4 and Figure 6 shown, in some embodiments, the two pipelines 1 corresponding to the first column of the first row of the rectangular array and the first column of the third row of the rectangular array are communicated through the inline pipe 5 and serve as the seventh flow channel 12;

[0088] At the position between the seventh flow channel 12 and the fifth flow channel 10 corresponding to the third column of the rectangular array, there is another pipeline connected to the control device 2 as the eighth flow channel;

[0089] The seventh flow channel 12 and the eighth flow channel form a fourth flow circuit;

[0090] The fourth flow circuit is used to connect with the fourth functional component;

[0091] The external connection pipe 4 of the seventh flow channel 12 extends outward along the vertical direction of the third column of the rectangular array;

[0092] The eighth flow channel extends outward along the vertical direction of the third column of the rectangular array and is located between the external connection pipe 4 of the fifth flow channel 10 and the reference plane.

[0094] In some embodiments, each functional component serves as an environmental element.

[0095] In some embodiments, a liquid injection pipe 13 and an air outlet pipe 14 are further provided on the outer side of the runner plate. A combination formed by a liquid injection pipe 13 and an air outlet pipe 14 is communicated with any one of the inline pipes 5, so as to facilitate the exhaust and liquid injection of each pipeline in the runner plate, maintain the pressure balance in each pipeline and is conducive to the replacement of the coolant.

[0096] The present invention further provides a flow splitting assembly, which includes the above-mentioned runner plate and a control device 2. The control device 2 includes more than one valve core. The control device 2 includes a reference plane 3 that is matched with a reference plane and has a flange docking structure. All pipelines 1 in the runner plate are connected to the included valve cores through the reference plane 3, and the connection or disconnection between each pipeline 1 and other pipelines 1 is controlled by the movement of the valve core.
