Description

Technical Field

[0001] The present invention relates to a high-precision processing device for the production of new energy vehicle heat exchangers, and particularly to a high-precision processing device for the production of the core body of new energy vehicle heat exchangers. Background Art

[0002] The large-scale microchannel heat exchanger has the advantages of being structurally compact, lightweight, and efficient, and is very suitable as a heat exchanger for the air conditioning system of new energy vehicles; in the prior art, the processing process of the above-mentioned heat exchanger core body generally involves first cutting a sheet, then using a bending machine to bend the middle plate into a plate body with continuous 90° bends, and then welding the upper plate and the lower plate to the top and bottom of the wavy plate body to form dense microchannels in the middle;

[0003] The equipment and processes required for the above processing method are numerous and the processing efficiency is low. In particular, the welding requirements are high and the time consumed is long. Moreover, since the solder joints are concentrated in a line, internal leakage points are inevitable, resulting in a high scrap rate of the heat exchanger core body processing; on the other hand, the heat exchange between the heat exchanger core body of this structure and the outside mainly occurs through the flat top plate and bottom plate, and the heat exchange area with the outside is small. Even if dense heat exchange fins are installed on the outside of the top plate and bottom plate, there is actually still a large room for improvement in its heat exchange effect. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art, and provide a high-precision processing device for the production of new energy vehicle heat exchangers, which has high processing efficiency, high precision, the heat exchanger core body processed by it is not easy to generate leakage points, and has high heat exchange efficiency.

[0005] The technical solution of the present invention is: a high-precision processing device for the production of new energy vehicle heat exchangers, including a housing, both ends of the housing are respectively provided with a feeding end and a discharging end, and two pressing roller groups, two guiding members corresponding to the two pressing roller groups, a hot pressing roller group and a shaping device are successively arranged in the housing from the discharging end to the feeding end direction;

[0006] The two pressing roller groups include an upper sheet pressing roller group and a lower sheet pressing roller group arranged vertically. The feeding end is provided with a corresponding upper blank plate feeding port and a lower blank plate feeding port. A coil reel, a coil guiding assembly and a pressing wheel are arranged between the lower blank plate feeding port and the lower sheet pressing roller group. The coil reel is arranged close to the lower blank plate feeding port for easy replacement of the coil, and the pressing wheel is arranged close to the lower sheet pressing roller group;

[0007] The upper sheet pressing roller group is composed of a first upper sheet pressing roller and a second upper sheet pressing roller. The first upper sheet pressing roller and the second upper sheet pressing roller are respectively provided with corresponding continuous arc-shaped concave and convex structures to press the upper blank plate into a continuous wavy upper sheet;

[0008] The lower sheet pressing roller group consists of a first lower sheet pressing roller and a second lower sheet pressing roller. The first lower sheet pressing roller and the second lower sheet pressing roller also respectively have corresponding continuous arc-shaped concave and convex structures. A first convex ring corresponding to the coil is provided between every two arc-shaped protrusions of the first lower sheet pressing roller to press the lower blank plate into a continuous wavy lower sheet and make the coil fit into the reserved groove of the lower sheet.

[0009] The hot pressing roller group consists of two hot pressing rollers. Electric heating rods are provided inside the two hot pressing rollers. The two hot pressing rollers respectively have continuous concave and convex structures corresponding to the shapes of the upper sheet and the lower sheet. The upper sheet and the lower sheet output by the upper sheet pressing roller group and the lower sheet pressing roller group are guided by two guiding members and input between the two hot pressing rollers to be hot pressed into a heat exchanger core blank.

[0010] One end of the shaper has an input end with a triangular cross-section. The input end is arranged close to the gap between the two hot pressing rollers. An input channel is provided inside the input end. A shaping channel is provided inside the shaper. The shapes of the input channel and the shaping channel both correspond to the shape of the heat exchanger core blank. The cross-section at the connection of the shaping channel and the input channel is in a trumpet shape. Continuous wavy protrusions corresponding to the shape of the heat exchanger core blank are also provided at the upper and lower ends inside the end of the shaping channel facing the input channel. The outlet end of the shaping channel is arranged close to the discharging end.

[0011] Furthermore, guide plates corresponding to the upper blank plate and the lower blank plate are respectively provided at the feeding end of the housing. The coil reel is arranged below the guide plate corresponding to the upper blank plate. One end of the guide plate has an end with a triangular cross-section and this end is arranged close to the upper sheet pressing roller group or the lower sheet pressing roller group.

[0012] Specifically, the coil guiding assembly is multiple groups of guiding wheels. The multiple groups of guiding wheels are arranged obliquely between the coil reel and the lower sheet pressing roller group. One group of guiding wheels close to the lower sheet pressing roller group among the multiple groups of guiding wheels is the driving wheel.

[0013] Specifically, there are multiple pressing wheels. The multiple pressing wheels are rotatably connected to a rod body. A groove is provided in the middle of the pressing wheel. A second convex ring corresponding to the coil is provided in the middle of the groove. While pressing the coil into the reserved groove on the lower blank plate, the pressing wheel leaves creases on the lower blank plate on both sides of the reserved groove.

[0014] Furthermore, a heating component is also provided on the input end of the shaper.

[0015] Specifically, the guiding member is a hollow plate body. One end of the guiding member is respectively arranged close to the upper sheet pressing roller group or the lower sheet pressing roller group. The other end of the guiding member is arranged close to the hot pressing roller group, so that the upper sheet and the lower sheet are bent by a certain amplitude after being output by the upper sheet pressing roller group or the lower sheet pressing roller group and are sent to the hot pressing roller group.

[0016] Further, one end of the guiding member close to the upper sheet pressing roller group or the lower sheet pressing roller group has an arc-shaped bending end, the end of the bending end is an arc end, one side of the bending end is provided with a guiding block, and the guiding block and the bending end form a trumpet-shaped guiding opening to prevent the upper sheet or the lower sheet from being unable to be correctly guided.

[0017] Further, a preheating assembly is also arranged inside the guiding member.

[0018] Further, a guiding roller is also arranged on one side of the guiding member.

[0019] Further, a triangular guiding block is arranged between the ends of the two guiding members facing the hot pressing roller group, and one end angle of the triangular guiding block is arranged close to the hot pressing roller group.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. In the present invention, the upper sheet and the lower sheet are formed by being pressed by the high-precision upper sheet pressing roller group and the lower sheet pressing roller group, and then are pressed into one body by the high-precision hot pressing roller group. The processing process of the intermediate plate is omitted. It is only necessary to pre-cut the blank plate and process a reserved groove on the lower blank plate, which simplifies the processing flow and effectively improves the processing efficiency;

[0022] 2. Both the upper blank plate and the lower blank plate are cut into long plate shapes or rolled shapes, and continuous processing can be carried out. The processed heat exchanger core blank can be made into a finished product after cutting, which can significantly improve the processing efficiency;

[0023] 3. By clamping a coil in the reserved groove, the coil is the welding (fusion welding) material. When the hot pressing roller group heats and presses, the upper and lower sheets are combined into one body. Due to the setting of the reserved groove, the melted coil can evenly fill the joint of the upper and lower sheets. The upper and lower sheets are firmly combined and reliable, which can effectively avoid the generation of leakage points and ensure the reliability of the heat exchanger core; and compared with the traditional brazing or laser welding methods, the welding (fusion welding) efficiency of the present invention is significantly improved, and the manufacturing cost of the structure used for welding is significantly reduced;

[0024] 4. The coil is arranged at the feeding end and is synchronously input into the lower sheet pressing roller group with the lower blank plate, realizing the automatic clamping and compaction of the coil, and the degree of automation is high;

[0025] 5. A pressing wheel is designed to simultaneously clamp the coil and leave an indentation on the lower blank plate, and it can prevent the reserved groove from being distorted when the lower blank plate is pressed, and one wheel can be used for multiple purposes;

[0026] 6. A high-precision shaper structure is designed to re-press and shape the heat exchanger core blank, ensuring that its upper and lower sheets are firmly combined, and keeping the heat exchanger core blank straight, which is beneficial to the smooth passage of the medium and ensures the reliability of the heat exchanger core finished product.

[0027] 7. The heat exchanger core processed by the present invention is in the shape of a sheet with dense round holes, and both its upper and lower ends are continuously bent arc surfaces, effectively increasing its heat exchange area and thus enhancing its heat exchange efficiency. Since the connection between the upper sheet and the lower sheet of the heat exchanger core is that the lower convex part of the upper sheet is inserted into the reserved groove and then welded (fused) by a coil, the joint is firm and reliable and is not prone to leakage points.

Detailed implementation mode

[0042] The technical solution of the present invention will be further specifically described below through embodiments in conjunction with the accompanying drawings.

[0043] As Figure 1 shown, a high-precision processing device for the production of a new energy vehicle heat exchanger includes a housing 1. The two ends of the housing 1 are respectively provided with a feed end and a discharge end. Inside the housing 1 from the discharge end to the feed end direction, two pressure roller groups, two guide members 2 corresponding to the two pressure roller groups, a hot pressing roller group and a shaper 3 are sequentially provided;

[0044] The two pressure roller groups include an upper sheet pressing roller group and a lower sheet pressing roller group arranged vertically. The feed end is provided with a corresponding upper blank plate feed inlet 4 and a lower blank plate feed inlet 5. Between the lower blank plate feed inlet 5 and the lower sheet pressing roller group, there are a coil reel 6, a coil guiding assembly 7 and a pressure roller 8. The coil reel 6 is arranged close to the lower blank plate feed inlet 5 for easy replacement of the coil. The pressure roller 8 is arranged close to the lower sheet pressing roller group to accurately press the coil into the reserved groove 16 on the lower blank plate and prevent it from shifting during the processing by the lower sheet pressing roller group;

[0045] As Figures 2 - 4 shown, the upper sheet pressing roller group is composed of a first upper sheet pressing roller 9 and a second upper sheet pressing roller 10. The first upper sheet pressing roller 9 and the second upper sheet pressing roller 10 are respectively provided with corresponding continuous arc-shaped concave and convex structures to press the upper blank plate into a continuous wavy upper sheet 14;

[0046] As Figures 5 - 8 shown, the lower sheet pressing roller group is composed of a first lower sheet pressing roller 11 and a second lower sheet pressing roller 12. The first lower sheet pressing roller 11 and the second lower sheet pressing roller 12 are also respectively provided with corresponding continuous arc-shaped concave and convex structures. A first convex ring 13 corresponding to the coil is arranged between every two arc-shaped protrusions of the first lower sheet pressing roller 11 to press the lower blank plate into a continuous wavy lower sheet 15 and make the coil fit into the reserved groove 16 of the lower sheet 15;

[0047] The hot pressing roller set consists of two hot pressing rollers. Electric heating rods 18 are arranged inside the two hot pressing rollers 17. The two hot pressing rollers 17 are respectively provided with continuous concave-convex structures corresponding to the shapes of the upper sheet 14 and the lower sheet 15. The upper sheet 14 and the lower sheet 15 output by the upper sheet roller set and the lower sheet roller set are guided by the two guiding members 2 and are input between the two hot pressing rollers 17 to be hot pressed into a heat exchanger core blank;

[0048] As Figure 9 and Figure 10 shown, one end of the shaper 3 has an input end 19 with a triangular cross-section. The input end 19 is arranged close to the gap between the two hot pressing rollers 17. An input channel 20 is arranged inside the input end 19. A shaping channel 21 is arranged inside the shaper 3. The shapes of the input channel 20 and the shaping channel 21 both correspond to the shape of the heat exchanger core blank. The cross-section at the connection between the shaping channel 21 and the input channel 20 is in a trumpet shape. At the upper and lower ends inside the end of the shaping channel 21 facing the input channel 20, there are also continuous wavy protrusions 22 corresponding to the shape of the heat exchanger core blank. The outlet end of the shaping channel 21 is arranged close to the discharging end.

[0049] In the above structure, the volumes of the input channel 20 and the shaping channel 21 are slightly larger than the volume of the heat exchanger core blank. The volume of the input channel 20 is slightly larger than the volume of the shaping channel 21. The gap between the continuous wavy protrusions 22 corresponds to the thickness of the heat exchanger core blank. The input channel 20 mainly ensures that the heat exchanger core blank can accurately enter the shaper 3 and pass through between the continuous wavy protrusions 22 to further compact the upper sheet 14 and the lower sheet 15. The setting of the shaping channel 21 mainly avoids the deformation of the heat exchanger core blank during the cooling process and keeps it in a straight shape.

[0050] The working process of the above structure is as follows: The pre-shaped upper blank plate and lower blank plate are input from the feeding end in a straight state. Among them, a pre-processed reserved groove 16 is provided on the lower blank plate; the upper blank plate enters the upper sheet pressing roller group for pressing, and the lower blank plate enters the lower sheet pressing roller group for pressing. Among them, before the lower blank plate is pressed, the coil is continuously clamped into the reserved groove 16 of the lower blank plate under the action of the coil guiding component 7 and the pressing wheel 8, and is pressed together with the lower blank plate; the pressed upper sheet 14 and lower sheet 15 are bent under the action of the guiding member 2 and conveyed to the hot pressing roller group. When the upper sheet 14 and the lower sheet 15 are copper plates, the coil is an aluminum sheet, and the hot pressing roller group maintains a temperature of 670°C - 900°C; when the upper sheet 14 and the lower sheet 15 are aluminum plates, the coil is a tin sheet, and the hot pressing roller group maintains a temperature of 240°C - 560°C; under the pressing action of the hot pressing roller group, the upper sheet 14 and the lower sheet 15 are combined, and the coil located at the joint of the upper sheet 14 and the lower sheet 15 melts, playing a role similar to welding at the joint of the upper sheet 14 and the lower sheet 15; the pressed heat exchanger core blank is conveyed from the hot roller group to the shaper 3, and is pressed again by two continuous wavy protrusions 22 between the input channel 20 and the shaping channel 21 to ensure the reliability of the joint of the upper sheet 14 and the lower sheet 15, and then is shaped and cooled in the shaping channel 21 and output. After the output, the heat exchanger core blank is cut to a suitable length by a laser cutter to complete the production of the finished heat exchanger core, and the finished structure is as Figure 13 shown.

[0051] In another embodiment, as Figure 1 shown, guide plates 23 corresponding to the upper blank plate and the lower blank plate are respectively provided at the feeding end of the housing 1. The coil reel 6 is arranged below the guide plate 23 corresponding to the upper blank plate. One end of the guide plate 23 has an end with a triangular cross-section and this end is arranged close to the upper sheet pressing roller group or the lower sheet pressing roller group. The setting of the guide plate 23 is mainly to prevent the upper blank plate and the lower blank plate from being bent during the input process.

[0052] In another embodiment, the coil guiding component 7 is a plurality of guiding wheels, and the plurality of guiding wheels are arranged obliquely between the coil reel 6 and the lower sheet pressing roller group. One group of guiding wheels close to the lower sheet pressing roller group among the plurality of guiding wheels is a driving wheel.

[0053] In another embodiment, as Figure 11 shown, there are a plurality of the pressing wheels 8. The plurality of pressing wheels 8 are rotatably connected to a rod body 24. The middle of the pressing wheel 8 has a groove 25, and the middle of the groove 25 has a second convex ring 26 corresponding to the coil. While the pressing wheel 8 presses the coil into the reserved groove 16 on the lower blank plate, creases are left on the lower blank plate on both sides of the reserved groove 16, so that when the lower blank plate is pressed and bent by the lower sheet pressing roller group, the reserved groove 16 is not easily deformed, and further ensures that the coil is not easily disengaged.

[0054] In another embodiment, a heating component is further provided on the input end 19 of the shaper 3 to prevent the heat exchanger core blank from cooling too quickly, so that the two continuous wavy protrusions 22 cannot effectively perform the re-pressing function again.

[0055] In another embodiment, as Figure 1 shown, the guide member 2 is a hollow plate body. One end of the guide member 2 is respectively disposed close to the upper sheet pressing roller group or the lower sheet pressing roller group, and the other end of the guide member 2 is disposed close to the hot pressing roller group, so that the upper sheet 14 and the lower sheet 15 are bent by a certain amplitude after being output from the upper sheet pressing roller group or the lower sheet pressing roller group and are fed to the hot pressing roller group.

[0056] In another embodiment, as Figure 12 shown, the end of the guide member 2 close to the upper sheet pressing roller group or the lower sheet pressing roller group has an arc-shaped bent end 27. The end of the bent end 27 is a circular arc end. A guide block 28 is provided on one side of the bent end 27. The guide block 28 and the bent end 27 form a horn-shaped guide opening to prevent the upper sheet 14 or the lower sheet 15 from being incorrectly guided.

[0057] In another embodiment, a preheating component is further provided in the guide member 2 to increase the melting speed of the coil so that it can indeed achieve an effect similar to welding.

[0058] In another embodiment, a guide roller 29 is further provided on one side of the guide member 2 to prevent the upper sheet 14 or the lower sheet 15 from being bent during the process of being fed to the hot pressing roller group.

[0059] In another embodiment, a triangular guide block 30 is further provided between the ends of the two guide members 2 facing the hot pressing roller group. One end angle of the triangular guide block 30 is disposed close to the hot pressing roller group to ensure that the upper sheet 14 and the lower sheet 15 can be correctly fed between the hot pressing roller group.
