[0002] The unique multi-channel and thin-wall structure of the microchannel tube and the heat dissipation microchannel tube aluminum profile can achieve efficient heat exchange. When heat is transferred to the microchannel tube, the heat will quickly diffuse within the channel and exchange heat with the cooling medium (such as air, water, etc.) flowing in the channel, thereby quickly dissipating the heat, greatly improving the heat dissipation efficiency.

[0003] Extrusion molding is an important step in the processing of microchannel aluminum tubes. It is necessary to place the heated billet into the extrusion barrel of the extruder, and apply pressure through the extrusion rod to make the billet plastically deform under the constraint of the mold, thereby extruding the microchannel tube aluminum profile of the required shape and size. However, the sizes of the billets are different. When the billet is placed in the extrusion barrel, the billet often cannot face the mold mouth, and there is friction between the billet and the extrusion barrel, which makes it difficult for the billet to enter the mold well during the extrusion process.

[0025] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0026] First embodiment

[0027] Please refer to Figure 1 、 Figure 2 and Figure 3 ,in, Figure 1 This is a structural schematic diagram of the first embodiment of the electric vehicle battery core heat dissipation microchannel tube aluminum profile extrusion die provided by the utility model; Figure 2 for Figure 1 The side and rear structure diagram shown; Figure 3 for Figure 1 The internal structure of the extrusion barrel is shown in the figure. The aluminum extrusion die for the electric vehicle battery core heat dissipation microchannel tube comprises: an extrusion barrel 1, a surface of which is provided with a limit assembly 2, which comprises a hydraulic cylinder 21, a movable plate 22, and a roller 23;

[0028] A surface cleaning assembly 3 is provided at the rear end of the extrusion cylinder 1 and includes a limiting rod 31, an arc block 32 and a cleaning block 33;

[0029] The mold assembly 4 is arranged at the front end of the extrusion cylinder 1 , and the mold assembly 4 includes an inner mold 41 and an outer mold 42 .

[0030] The extrusion cylinder 1 is square in shape and has a square groove inside. The function of the limiting component 2 is to limit the blank, the function of the surface cleaning component 3 is to clean impurities on the surface of the blank, and the function of the mold component 4 is to shape its internal shape and extrude the blank.

[0031] The hydraulic cylinder 21 is fixedly mounted on the surfaces of the four ends of the extrusion cylinder 1 , the movable plate 22 is fixedly connected to one end of the hydraulic cylinder 21 , and the roller 23 is movably connected to the inner surface of the movable plate 22 .

[0032] There are multiple limit assemblies 2, which are respectively arranged on the surfaces of the four ends of the extrusion cylinder 1. Each group of limit assemblies 2 includes multiple hydraulic cylinders 21 and multiple rollers 23. Each group of hydraulic cylinders 21 is respectively connected in an array to the outer surfaces of the four ends of the extrusion cylinder 1. The movable plate 22 is U-shaped and is respectively fixedly connected to the surface of the hydraulic cylinder 21 embedded in one end of the extrusion cylinder 1, and the surface of each roller 23 is equipped with multiple rollers 23 for rotation in an array, so that the movable plate 22 is pushed to move by the hydraulic cylinder 21. The distance between the upper and lower and left and right rollers 23 can be adjusted according to the diameter and length of the billet, so that the billet is always in the middle position and the friction on the billet surface is reduced.

[0033] The limiting rod 31 is movably embedded in the surface of the front end of the extrusion cylinder 1, one end of the limiting rod 31 is fixedly connected to the surface of the front end of the hydraulic cylinder 21, the arc block 32 is fixedly connected to the front end surface of the movable plate 22, and the cleaning block 33 is fixedly installed on the inner surface of the arc block 32.

[0034] There are two surface cleaning components 3, and four plates are fixedly connected to the surface of the rear end of the extrusion cylinder 1. Each group of surface cleaning components 3 includes two limit rods 31, two arc blocks 32 and two cleaning blocks 33. The two limit rods 31 in each group are movably embedded in the surfaces of the left and right connecting plates and the upper and lower connecting plates. The two cleaning blocks 33 in each group are respectively fixedly connected to one end of the two limit rods 31 close to the center, and the two cleaning blocks 33 are respectively fixedly connected to the inner surfaces of the two arc blocks 32. When the movable plate 22 moves, the arc block 32 can be driven to move, so that the distance between the two arc blocks 32 adapts to the diameter of the blank, and the two groups of surface cleaning components 3 are staggered.

[0035] The inner mold 41 is fixedly mounted on the outer surface of the front end of the extrusion cylinder 1 , and the outer mold 42 is fixedly mounted on the surface of the inner mold 41 .

[0036] The inner surfaces of the inner mold 41 and the outer mold 42 are formed into a microchannel shape, so that when the blank enters the inner mold 41 and the outer mold 42, the blank is squeezed and fits with the inner surfaces of the inner mold 41 and the outer mold 42 to form the blank.

[0037] The working principle of the aluminum profile extrusion die for electric vehicle battery core heat dissipation microchannel tube provided by the utility model is as follows:

[0038] First, the hydraulic cylinder 21 is started according to the size of the billet, and the four movable plates 22 respectively drive the rollers 23 on their surfaces to move until the rollers 23 can be connected to the surfaces around the billet. The billet is pushed into the interior of the extrusion cylinder 1 through the hydraulic cylinder 1, and passes between the arc blocks 32. The cleaning block 33 is connected to the surface of the billet to wipe off the impurities on the surface of the billet. The surface of the billet entering the extrusion cylinder 1 is connected to the surface of the roller 23. The friction between the billet and the surface of the roller 23 is partially converted into the rotational force of the roller 23, and the roller 23 rotates until the billet enters the interior of the inner mold 41 and the outer mold 42 for extrusion molding and discharges from the front end of the extrusion cylinder 1.

[0039] Compared with related technologies, the electric vehicle battery core heat dissipation microchannel tube aluminum profile extrusion die provided by the utility model has the following beneficial effects:

[0040] The utility model provides an aluminum profile extrusion die for heat dissipation microchannel tubes for electric vehicle battery cells. The position of a roller 23 can be adjusted by telescoping a hydraulic cylinder 21 according to the size of the blank, thereby limiting the surface of the blank. At the same time, the rolling of the roller 23 reduces the friction force on the surface of the blank, which helps the blank to enter the interior of the die assembly 4.

[0044] The support plate 51 is L-shaped, with one end fixedly connected to the bottom of the rear end of the extrusion cylinder 1. The top of the support seat 52 is arc-shaped, and the front end is fixedly connected to the rear end of the bottom movable plate 22. The bottom of the support seat 52 is connected to a limiting plate, so that when the movable plate 22 moves, it can drive the support seat 52 to move up and down, and the support seat 52 is arc-shaped, so that the blank is always on the surface directly above the support seat 52.

[0045] One end of the support seat 52 is fixedly connected to the rear end of the movable plate 22 , and a hydraulic push rod 53 is fixedly installed on the rear end of the support plate 51 .

[0046] The blank is placed inside the support seat 52 , and the hydraulic push rod 53 can push the rear end of the blank, so that the blank slides toward the front end on the surface of the support seat 52 into the interior of the support plate 51 .

[0047] The working principle of the aluminum profile extrusion die for electric vehicle battery core heat dissipation microchannel tube provided by the utility model is as follows:

[0048] The blank is placed on the support seat 52 , and then the hydraulic push rod 53 is activated to push the blank along the surface of the support seat 52 into the interior of the extrusion cylinder 1 and connect with the rollers 23 on the surfaces of the four movable plates 22 .
