[0077] For the convenience of explanation and understanding, in the embodiment of the present invention, a three-dimensional coordinate system of XYZ axes is established, wherein the first positive direction is the direction of left rotation around the Y axis, and the first negative direction is the direction of right rotation around the Y axis; the second positive direction is the direction of right rotation around the X axis, and the second negative direction is the direction of left rotation around the X axis; the third positive direction is the clockwise direction around the Z axis, and the third negative direction is the counterclockwise direction around the Z axis.

[0078] Example 1

[0079] See also Figures 1 to 13 Embodiment 1 of the present invention provides a method for manufacturing an interactive heat exchanger, the method comprising the steps of:

[0080] Step 1: The backing plate 1 and the flow plate 2 are stamped to form a punching sheet. The backing plate 1 and the flow plate 2 are stamped on different stamping equipment to complete the part punching. Compared with the existing etching technology, the stamping process has high production efficiency and low cost. In addition, the quality and size stability of the backing plate 1 and the flow plate 2 obtained by stamping are high, and the overall yield rate is also high.

[0081] Step 2: Clean the punched backing plate 1 and the flow plate 2. In order to prevent the flow plate 2 and the backing plate 1 from being attached with oil, iron filings and other foreign matter on their surfaces due to the stamping process, equipment and on-site environment during the stamping process. In this step, the flow plate 2 and the backing plate 1 are fully cleaned to remove dirt to ensure the reliability of subsequent welding and the stability of the welding process. In this step, hydrocarbon cleaning and ultrasonic cleaning can be used to clean the flow plate 2 and the backing plate 1.

[0082] Step 3: The cleaned pad 1 at least includes a first pad 100, a second pad 200, a third pad 300 and a fourth pad 400; the flow plate 2 at least includes a first flow plate 500 and a second flow plate 600; and the first pad 100, the second pad 200, the first flow plate 500, the third pad 300, the fourth pad 400 and the second flow plate 600 are stacked in sequence; the pad channel gaps between adjacent pads 1 are flipped 180 degrees and staggered and alternating to form a heat exchange mechanism with independent main channels 3 and secondary channels 4.

[0083] Step 4: Weld the heat exchange mechanism formed by the pad 1 and the flow plate 2 by atomic diffusion welding, and at the same time, weld the outlet and inlet parts to the collecting side cover.

[0084] Step 5: The welded heat exchange mechanism and the collector side cover welded with the outlet and inlet parts are welded into a whole by brazing;

[0085] Step 6: Perform weld leakage detection and pressure resistance test on the whole after welding. When testing weld leakage, the whole can be connected to a helium leak detector for testing; after passing the weld leakage test, the pressure resistance test can be performed.

[0086] Step 7: Surface treatment of the whole. Connect the flow channel of the qualified product that has passed the pressure test into the anodizing solution, and perform surface treatment on the heat exchange metal surface in the channel to enhance the anti-corrosion and anti-fouling properties to obtain the finished heat exchanger.

[0087] Step 8: Clean and package the whole. Nitrogen can be used for cleaning.

[0088] Specifically, in the third step, the first pad 100, the second pad 200, the first flow plate 500, the third pad 300, the fourth pad 400 and the second flow plate 600 are sequentially stacked;

[0089] In order to facilitate the production of the pad 1, so as to better improve the production efficiency of the heat exchanger and reduce its manufacturing cost, the first pad 100, the second pad 200, the third pad 300 and the fourth pad 400 can be set to be completely the same square shape, and the second pad 200 can be set along the first positive direction (i.e., the first positive direction) with the first pad 100 as a reference. Figure 7 The direction of left rotation around the Y axis) flips itself 180 degrees;

[0090] The third pad 300 turns 180 degrees along the first positive direction and then moves along the third positive direction (i.e. Figure 7 Rotate 90 degrees around the Z axis clockwise.

[0091] The fourth pad 400 is rotated 90 degrees along the third positive direction. That is, when the fourth pad 400 is taken as a reference by the third pad 300, the fourth pad 400 can be rotated along the second positive direction (i.e., the third pad 300). Figure 7 The direction of right rotation around the X axis) flips itself 180 degrees.

[0092] Of course, in order to expand the heat exchange area of ​​the heat exchange mechanism and ensure the production efficiency of the manufacturing, Figure 7 and Fig. 9 The first pad 100, the second pad 200, the third pad 300 and the fourth pad 400 can be set to a rectangular shape, the structure of the first pad 100 and the second pad 200 can be set to be exactly the same, the third pad 300 and the fourth pad 400 can be set to be exactly the same, the pad channel notch of the first pad 100 can be set in its own length direction, and the pad channel notch of the third pad 300 can be set in its own width direction.

[0093] At this time, the first pad 100 can be used as a reference to move the second pad 200 along the first positive direction (i.e., the Figure 7 The direction of left rotation around the Y axis) flips itself 180 degrees;

[0094] Taking the third pad 300 as a reference, move the fourth pad 400 along the second positive direction (i.e. Figure 7 The direction of right rotation around the X axis) flips itself 180 degrees.

[0095] The manufacturing method of the interactive heat exchanger provided in this embodiment is to stamp the flow plate 2 and the pad 1 into sheets by a stamping process, which can improve the production efficiency of the heat exchanger and avoid too long processing time; then the pad 1 includes a first pad 100, a second pad 200, a third pad 300 and a fourth pad 400, and the flow plate 2 includes a first flow plate 500 and a second flow plate 600, and the first pad 100, the second pad 200, the first flow plate 500, the third pad 300, the fourth pad 400 and the second flow plate 600 are stacked in sequence, and the pad channel gaps between adjacent pads 1 are removed. The ports are flipped 180 degrees and staggered to form independent main channels and auxiliary channels, so that the volume of the stamped heat exchanger can also be reduced; the heat exchange mechanism formed by the pad 1 and the flow plate 2 is welded by atomic diffusion welding, and the welded heat exchange mechanism and the collecting side cover welded with the outlet and inlet parts are welded into a whole by brazing, which can improve the accuracy and yield of the heat exchanger; the heat exchanger is manufactured by a method combining stamping process, atomic diffusion welding and brazing, which can not only manufacture a smaller heat exchanger, but also simplify its manufacturing process, reduce costs and improve yield.

[0096] Example 2

[0097] Combination Figures 1 to 13 Embodiment 2 of the present invention further provides an interactive heat exchanger manufactured based on the manufacturing method of the interactive heat exchanger provided in Embodiment 1, and the interactive heat exchanger includes a heat exchange mechanism, an upper sealing plate 5, a lower sealing plate 6, a first collecting side cover 7, a second collecting side cover 8, a third collecting side cover 9, and a fourth collecting side cover 10.

[0098] The heat exchange mechanism includes a plurality of heat exchange components stacked on top of each other, each heat exchange component includes a first pad 100, a second pad 200, a first flow plate 500, a third pad 300, a fourth pad 400 and a second flow plate 600 stacked in sequence.

[0099] The first pad 100 and the second pad 200 are completely identical, and are arranged alternately and staggered by 180 degrees; the third pad 300 and the fourth pad 400 are completely identical, and are arranged alternately and staggered by 180 degrees; the first flow plate 500 and the second flow plate 600 are completely identical.

In this embodiment 2, the second pad 200 can be used as a reference, and the third pad 300 is arranged along the third negative direction (i.e., the attached Figure 7The second pad current collecting groove 220 and the third pad current collecting groove 320 are staggered and alternately arranged to form a main channel 3 and a secondary channel 4 that are not connected to each other.

[0101] The upper sealing plate 5 is arranged at the top of the heat exchange mechanism; the lower sealing plate 6 is arranged at the bottom of the heat exchange mechanism.

[0102] The first collecting side cover 7 is arranged at the entrance of the main channel 3;

[0103] The second current collecting side cover 8 is arranged opposite to the first current collecting side cover 7 and is arranged at the outlet of the main channel 3;

[0104] The third collecting side cover 9 is arranged at the inlet of the secondary channel 4;

[0105] The fourth current collecting side cover 10 is arranged opposite to the third current collecting side cover 9 and is arranged at the outlet of the secondary channel 4 .

[0106] In this embodiment, the refrigerant can be input from the first collecting side cover 7, pass through the main channel 3 formed by the heat exchange component, and then be output from the second collecting side cover 8; the material to be heat exchanged (for example, water or air) can be input from the third collecting side cover 9, pass through the 4 formed by the heat exchange component, and then be output from the fourth collecting side cover 10 to complete the heat exchange.

[0107] It can be understood that the heat exchanger is stacked in sequence by stacking the first pad 100, the second pad 200, the first flow plate 500, the third pad 300, the fourth pad 400 and the second flow plate 600, and the first pad 100 and the second pad 200 are completely identical and are turned over 180 degrees and staggered, the third pad 300 and the fourth pad 400 are completely identical and are turned over 180 degrees and staggered, and the first flow plate 500 and the second flow plate 600 are completely identical; so that adjacent pads can be formed The main channel 3 and the secondary channel 4 are not connected to each other, and a first flow plate 500 is arranged between the second pad 200 and the third pad 300, and a second flow plate 600 is arranged between the fourth pad 400 and the first pad 100 of the next heat exchange component, so that the main channel 3 and the secondary channel 4 can fit tightly to improve the heat exchange efficiency. It can also make the volume of the heat exchanger smaller even if it is manufactured by a stamping process, avoiding excessively long molding time, which can improve production efficiency and simplify the processes required for production, and ultimately reduce costs.

[0108] Specifically, the first through-flow plate 500 is provided with a first through-flow plate collecting groove 510 and a first through-flow plate recess cavity 520 .

[0109] The second pad 200 is provided with a second pad hollow hole 230 , and the second pad hollow hole 230 matches the first flow plate recess cavity 520 .

[0110] The fourth pad 400 is provided with a fourth pad hollow hole 430 , and the fourth pad hollow hole 430 matches with the second flow plate recessed cavity 620 of the second flow plate 600 .

[0111] After the first pad 100, the second pad 200, the first flow plate 500, the third pad 300, the fourth pad 400 and the second flow plate 600 are stacked in sequence;

[0112] The second pad channel notch 210 of the second pad 200 and the first pad channel notch 110 of the first pad 100 form a main channel 3;

[0113] The fourth pad channel notch 410 of the fourth pad 400 and the third pad channel notch 310 of the third pad 300 form a secondary channel 4 .

[0114] A first pad channel notch 110 is provided on the first pad 100, a second pad channel notch 210 is provided on the second pad 200, the first pad 100, the second pad 200 and the first flow plate 500 are overlapped, and the third pad 300, the fourth pad 400 and the second flow plate 600 are also arranged in this way, so that the inlet and outlet of the formed main channel 3 and the secondary channel 4 are both groove open structures, such as Figures 9 to 11 The main channel 3 and the auxiliary channel 4 are "Z" shaped channel structures.

[0115] When the heat exchanger is working, the total amount of refrigerant or other heat exchange medium flowing per unit time is no longer limited by the flow area of ​​the main channel 3 and the secondary channel 4. The heat exchange plates can be infinitely stacked according to the area required for the heat exchange, until the area at the inlet or outlet of the heat exchange channel matches the flow area of ​​the pipeline in the refrigeration system, thereby achieving the heat exchange target.

[0116] Furthermore, in order to improve the strength of each pad, the pads are integrally connected and are not disconnected, and the compressive strength of the heat exchanger may also be increased after stacking. In this embodiment, the first pad 100 is provided with a reinforcing rib 140 .

[0119] The guide island 530 can be set in the heat exchange area of ​​the first flow plate 500 (i.e., the area in the middle position of the first flow plate 500). After stacking, the protrusions of the guide island 530 on two adjacent flow plates in the heat exchanger (for example, the first flow plate 500 and the second flow plate 600) abut against each other to ensure that the two adjacent flow plates can be connected together during welding, thereby increasing the pressure bearing strength.

[0120] At the same time, two adjacent flow plates can be stacked with a 180-degree offset from each other, and the guide island 530 can be a polygon. The protrusions of the guide island 500 abut against each other to form a certain gap for the refrigerant or water to flow through, and the effective heat exchange area in the heat exchange zone will not be reduced due to the excessive size of the welding surface.

[0121] In this embodiment, in order to prevent the stacked sheets from being misaligned when the heat exchanger is stacked, positioning pin holes may be provided to position each punching sheet.

[0122] Specifically, positioning pin holes 700 are respectively provided on the first pad 100 , the second pad 200 , the first flow plate 500 , the third pad 300 , the fourth pad 400 and the second flow plate 600 .

[0123] Surrounding the positioning pin hole 700 , welding groove side surfaces 710 , welding groove bottom surfaces 720 and positioning groove side surfaces 730 are respectively provided on the first pad 100 , the second pad 200 , the first flow plate 500 , the third pad 300 , the fourth pad 400 and the second flow plate 600 .

[0124] After the punching sheets of the heat exchanger are stacked, the side surface 710 of the welding groove forms a clearance fit with the welding surface of the collector side cover, which is used to accommodate the solder during welding to achieve high-pressure sealing.

[0125] The bottom surface 720 of the welding groove fits with the reference plane of the guide positioning boss on the collecting side cover so that there is no gap between the two surfaces to ensure that solder and foreign matter will not fall into the inlet and outlet of the main channel 3 and the secondary channel of the heat exchanger during the welding process. At the same time, this surface is also the end face of the positioning groove.

[0126] The side surface 730 of the positioning groove matches with the side surfaces around the guide positioning boss on the collector side cover so that the centers of the two are aligned, thereby ensuring that the weld gaps around the four side covers are uniform.

[0127] Furthermore, in order to ensure that each pad has sufficient strength to withstand the high refrigeration pressure without being blown up or torn during atomic diffusion welding, in this embodiment, pad welding and pressing positions 740 are also provided on the first pad 100, the second pad 200, the third pad 300 and the fourth pad 400. The pad welding and pressing positions 740 are provided on the notches of each pad channel.

[0128] In this embodiment, the first pad 100 is square in shape, and the first pad 100, the second pad 200, the third pad 300 and the fourth pad 400 are exactly the same. The appearance of the first flow plate 500 and the second flow plate 600 is the same as that of the first pad 100. In this way, a pad and a flow plate can be manufactured, and then the first pad 100, the second pad 200, the first flow plate 500, the third pad 300, the fourth pad 400 and the second flow plate 600 are placed in sequence according to different positions to obtain the interactive heat exchanger of this embodiment, which can improve manufacturing efficiency.

[0129] Example 3

[0130] Combination Fig.12 and Fig.13 The interactive heat exchanger provided in this embodiment is basically the same as that in Embodiment 2, except that the first pad 100 in the interactive heat exchanger provided in this embodiment is rectangular, and the second pad 200, the first flow plate 500, the third pad 300, the fourth pad 400 and the second flow plate 600 have the same shape as the first pad 100, the second pad 200 is completely the same as the first pad 100, and the fourth pad 400 is the same as the third pad 300. While expanding the area of ​​the main channel 3 and the secondary channel 4 of the heat exchanger to expand the heat exchange efficiency, it can also make the manufacture of the heat exchanger more convenient and the manufacturing efficiency higher. In this way, two pads and one flow plate can be manufactured, and then the first pad 100, the second pad 200, the first flow plate 500, the third pad 300, the fourth pad 400 and the second flow plate 600 are placed in sequence according to different positions to obtain the interactive heat exchanger of this embodiment, which can improve the manufacturing efficiency.

[0131] The first pad 100, the second pad 200, the third pad 300 and the fourth pad 400, as well as the first flow plate 500 and the second flow plate 600 in this embodiment 3 can be based on the pads and flow plates provided in embodiment 2, and a square pad or flow plate can be extended along the length direction. Figure 7 The first pad 100 of the second embodiment is extended along the Y-axis direction to form a square with its own size to obtain the first pad 100 of the third embodiment (such as Fig.12 ); The first flow plate 500 of embodiment 2 is extended along the Y-axis direction to form a square with its own size, and the first flow plate 500 of embodiment 3 can also be obtained (such as Fig.12 ).

[0132] Of course, based on the pad and flow plate provided in Example 2, they can be extended along the X-axis direction and the Y-axis direction respectively, so that pads and flow plates of different sizes can be obtained to manufacture heat exchangers with different heat exchange capacities, making the interactive heat exchanger more flexible.

[0133] Example 4

[0134] Combination Figure 4 The interactive heat exchanger provided in this embodiment is basically the same as that in Embodiment 2, except that the interactive heat exchanger provided in this embodiment further includes a first fan 810 and a second fan 820, the first fan 810 is connected to the third collecting side cover 9, and the second fan 820 is connected to the fourth collecting side cover 10, so as to realize heat exchange between wind and refrigerant.

[0135] Example 5

[0136] Combination Figures 1 to 13 The interactive heat exchanger provided in this embodiment is basically the same as that in Embodiment 2, except that the first flow plate 500 and the second flow plate 600 of the interactive heat exchanger provided in this embodiment can be completely identical flat plate parts, so that the heat exchanger is easier to manufacture, improves manufacturing efficiency, and thus reduces costs.

[0137] When the first flow plate 500 and the second flow plate 600 are flat plates, the first flow plate 500 and the second flow plate 600 may be made of the same material, and the channels formed by repeated stacking are relatively straight and have the same channel height.

[0138] Of course, a recessed structure may also be provided between the first flow plate 500 and the second flow plate 600; in this case, the first flow plate 500 and the second flow plate 600 may also be made of the same material, and the channel formed by repeatedly stacking the end faces (or recessed direction) in the same direction is tortuous and has the same channel height.

[0139] The first flow plate 500 and the second flow plate 600 are made of the same material, and can be stacked repeatedly with the end faces (or recessed directions) facing each other to form a tortuous channel with inconsistent channel heights, thereby achieving the desired heat exchange effect for different heat exchange materials.

[0140] When the first flow plate 500 and the second flow plate 600 are not made of the same material, the recess depths of the two can be set to different depths, so as to achieve the situation when the channel height ratios in the two directions are greatly different through the same / backward stacking. For example, the height of a single channel on the refrigerant side is 0.03, and the channel height on the air / water side is 0.15. At this time, the height ratio of the two channels is 1:5, which can better condense or evaporate the refrigerant and improve the heat exchange efficiency.
