Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooling pipeline, in particular to an assembling device and method of large-diameter multi-branch cooling pipeline. BACKGROUND

[0002] Electric vehicles are rapidly developing due to the advantages of no tail gas emission and no pollution to the environment, and have become the future development direction of the automobile field. The factors restricting the development of electric vehicles at present mainly include two aspects: one is the short battery endurance; the second is the long charging time. The problem of short battery endurance needs to be solved by the development of lithium battery technology to improve the energy density of lithium batteries, but the corresponding charging time of lithium batteries is further prolonged.

[0003] The problem of long charging time involves the technology of super high-power charging pile. The super high-power direct current integrated pile generates a large amount of heat while charging quickly, which needs to be cooled and dissipated in time. The mainstream cooling device at present is the heat exchange and dissipation of cooling liquid, which circulates in the cooling gas pipeline to achieve the purpose of cooling and heat dissipation. For example, Chinese patent application No. 202210602330.2 discloses a cooling pipeline for energy storage, a cooling method and an energy storage device. The cooling pipeline for energy storage includes an annular inlet main pipe, an annular outlet main pipe and at least one cooling branch pipe. The inlet ends of the cooling branch pipes are independently connected to the annular inlet main pipe, and the outlet ends of the cooling branch pipes are independently connected to the annular outlet main pipe. During the cooling process, the cooling medium enters the annular inlet main pipe and enters each cooling branch pipe for cooling and temperature reduction.

[0004] Most of the current super charging pile inverter cooling pipelines use metal pipelines and plastic pipelines. The communication mode of the main pipeline and the branch pipeline in the metal pipeline is mostly welding. The specific implementation method is to drill holes in seamless steel pipes or roll-welded metal pipes, and then weld tee pipe nozzles after drilling. The disadvantages are high cost, the use of corrosion-resistant stainless steel material for metal pipes, and multiple processing steps. After multiple holes are opened in the whole pipeline, welding is needed on the holes. The time consumption of a single work department is high, the total assembly time consumption is more than 20 minutes, and the efficiency is low. There are many welding points in a single product, and the traditional welding method produces porosity or virtual welding phenomenon, so the leakage risk of the whole product is very high. The forming method of the plastic pipeline is segmented injection molding and welding. The specific implementation method is to divide the long pipeline into 3-5 segments by plastic injection semi-finished products, and then weld each segment together. The disadvantages are that the product needs to be developed into 3-5 segments of injection mold and the corresponding welding tooling, so the total development cycle is very long; the mold cost is high, the tooling cost is high, resulting in high development cost; after the mold is fixed, if the size changes, all the molds are extremely easy to scrap.

[0061] Embodiment 1

[0062] Please refer to Figures 1-7The application provides an assembling device for large-diameter multi-branch cooling pipeline, which comprises a cooling main pipe 1, an inner plug 2, a sealing element 3, a conveyor 4 and a pusher 5, the cooling main pipe 1 is a plastic pipe and is prepared by an extrusion process, the cooling main pipe 1 is provided with three or more pipe holes 101, the pipe holes 101 are arranged along the axial direction of the cooling main pipe 1, all the pipe holes 101 are located on the same straight line, the intervals between adjacent pipe holes 101 are the same, the inner plug 2 passes through the pipe holes 101 and extends across the inside and outside of the cooling main pipe 1, the inner plug 2 provides a bearing sealing table for the sealing element 3, and the part of the inner plug 2 extending out of the cooling main pipe 1 is used as the connecting structure of external other elements, such as a bolt or a VDA male joint structure, the inner plug 2 can be replaced by the VDA male joint structure and is directly connected with the cooling branch pipe 6, in the embodiment, the inner plug 2 adopts the branch pipe nozzle with the VDA male joint structure and is directly connected with the cooling branch pipe 6, the sealing element 3 is arranged between the inner plug 2 and the cooling main pipe 1 and is used for sealing the connecting position of the inner plug 2 and the cooling main pipe 1 to avoid the leakage of cooling liquid, the conveyor 4 adopts a rod structure, preferably, the conveyor 4 is a circular rod structure, the diameter of the conveyor 4 is slightly smaller than the inner diameter of the cooling main pipe 1, so that the conveyor 4 can move in the cooling main pipe 1, the conveyor 4 is used for bearing the inner plug 2, when the conveyor 4 moves in the cooling main pipe 1, the conveyor 4 transports the inner plug 2 to the position of the pipe hole 101 of the cooling main pipe 1, the pusher 5 also adopts a rod structure and is used for pushing the inner plug 2 and the sealing element 3 out of the conveyor 4 and into the pipe hole 101, and in order to facilitate the insertion of the inner plug 2 and the sealing element 3 into the pipe hole 101, the diameter of the part of the inner plug 2 extending out of the cooling main pipe 1 is slightly smaller than the diameter of the pipe hole 101.

[0063] In the embodiment, the outer side of the conveyor 4 is symmetrically provided with a flat surface 401 along the length direction, a placing groove 402 is arranged on the flat surface 401 on one side, the placing groove 402 is used for placing the inner plug 2, the maximum size of the inner plug 2 is slightly smaller than the size of the placing groove 402, so that the inner plug 2 can be inserted into the placing groove 402, the length of the inner plug 2 is smaller than the diameter of the conveyor 4, and the depth of the placing groove 402 is greater than the length of the inner plug 2, so that the inner plug 2 can be completely placed into the placing groove 402.

[0064] In this embodiment, the conveyor 4 is provided with a push groove 403 along its length. The push groove 403 communicates with the insertion groove 402, and the insertion groove 402 is distributed on both sides of the push groove 403. The push groove 403 is a through groove that passes through the conveyor 4. The pusher 5 is inserted from one end of the push groove 403, and the cross-sectional size of the pusher 5 is slightly smaller than the cross-sectional size of the push groove 403, so that the pusher 5 can be smoothly inserted into the push groove 403. Preferably, the cross-section of the push groove 403 is a rectangular structure, and the cross-sectional structure of the pusher 5 is also a rectangular structure. The center point of the rectangular structure is located on the central axis of the conveyor 4, and the push groove 403 and the insertion groove 402 are connected at the middle.

Specifically, the tail of the inner plug is a regular hexagonal prism structure, and the prismatic groove is also a regular hexagonal groove. When the inner plug 2 is connected to the external structure, it can effectively prevent the inner plug 2 from rotating, which facilitates the installation of the external connector.

[0066] Example 2

[0067] The assembly device for the large-diameter multi-branch cooling pipe provided in Example 1 has been further optimized, such as... Figures 8-11 As shown, specifically, the sealing element 3 includes an inner sealing sleeve 301 and an outer sealing sleeve 302. Both the inner sealing sleeve 301 and the outer sealing sleeve 302 are made of rubber material that is resistant to aging and has good sealing effect. Preferred material is ethylene propylene rubber, which has good waterproof, acid and alkali resistance, and a long service life. The inner sealing sleeve 301 is located inside the cooling main pipe 1 and extends between the inner plug 2 and the cooling main pipe 1. The outer sealing sleeve 302 is located outside the cooling main pipe 1 and fits over the inner plug 2 that extends outside the cooling main pipe 1, used to seal the external connector and... The connection position of the cooling main pipe 1 is such that after the cooling branch pipe 6 is connected to the inner plug 2, the cooling branch pipe 6 abuts against the outer sealing sleeve 302. The outer sealing sleeve 302 seals the connection position of the cooling branch pipe 6 with the cooling main pipe 1 and the inner plug 2. In order to facilitate the fit between the outer sealing sleeve 302 and the cooling main pipe 1, the side of the outer sealing sleeve 302 near the cooling main pipe 1 is an arc-shaped structure. After the external connection structure is connected to the inner plug 2, the outer sealing sleeve 302 is squeezed so that the outer sealing sleeve 302 can fit against the outer wall of the cooling main pipe 1.

[0068] In the embodiment, the inner sealing sleeve 301 is provided with a boss 3011, which is a conical boss structure, and is arranged on the inner side of the cooling main pipe 1. The diameter of the boss 3011 is greater than the diameter of the pipe hole 101, which avoids the inner sealing sleeve 301 from being pulled out of the pipe hole 101. The boss 3011 is an arc surface structure, which can perfectly fit the inner side wall of the cooling main pipe 1. The design ensures the sealing effect. The inner sealing sleeve 301 needs to be sleeved with the inner plug 2 before installation. In order to facilitate the placement of the inner sealing sleeve 301, the annular groove 202 is arranged on the prismatic structure 201 of the inner plug 2, so that part of the boss 3011 of the inner sealing sleeve 301 can be embedded in the annular groove 202. The boss 3011 is partially interference-fitted with the annular groove 202, which realizes the positioning and fixing of the inner sealing sleeve 301.

[0069] In the embodiment, in order to further improve the sealing effect, the boss 3011 of the inner sealing sleeve 301 is provided with a sealing protrusion one 3012, which is arranged along the arc of the arc surface structure of the boss 3011, and can tightly fit the inner wall of the cooling main pipe 1. The bottom surface of the inner sealing sleeve 301 is provided with a sealing protrusion two 3013, which tightly fits the bottom of the annular groove 202. The outer side of the inner sealing sleeve 301 between the cooling main pipe 1 and the inner plug 2 is provided with a sealing protrusion three 3014. The inner sealing sleeve 301 is interference-fitted with the gap between the inner plug 2 and the inner wall of the pipe hole 101. The sealing protrusion three 3014 further provides the sealing effect.

[0070] Through the above structure design, the inner sealing sleeve 301 and the outer sealing sleeve 302 form a sealing member 3. The inner sealing sleeve 301 is arranged between the inner plug 2 and the cooling main pipe 1, and seals the connection between the inner plug 2 and the cooling main pipe 1. The outer sealing sleeve 302 is sleeved outside the inner plug 2 outside the cooling main pipe 1, and seals the connection position of the cooling branch pipe 6, the inner plug 2 and the cooling main pipe 1 when the inner plug 2 connects the cooling branch pipe 6. The design ensures the sealing effect, avoids the leakage between the cooling main pipe 1 and the cooling branch pipe 6, improves the safety performance, and greatly reduces the risk of leakage.
