Description

Technical Field

[0001] The invention relates to the technical field of condenser processing, and in particular to a condenser sheet forming process. Background Art

[0002] The enameled plate condenser is a commonly used heat exchange equipment. Its principle is to condense steam into liquid through heat exchange between the enameled heat exchange plate and the cooling medium. When high-temperature and high-pressure steam enters the enameled plate condenser, the steam contacts the surface of the heat exchange plate, and the heat in the steam is absorbed by the enameled plate and transferred to the cooling medium in the plate. At the same time, the heat in the cooling medium is also absorbed by the enameled plate and transferred to the other side of the cooling medium, causing it to be heated. After heat exchange, the steam condenses into liquid and is discharged from the system.

[0003] The main reasons for enameling the condenser plate include improving heat transfer capacity, enhancing corrosion resistance and increasing service life. These characteristics make enameled plate condensers have significant advantages in industrial applications.

[0004] The plate condenser is composed of two parallel heat exchange plates, which are sealed by side plates. The side plates and heat exchange plates form a chamber that can be filled with refrigerant liquid. Multiple parallel reinforcing ribs are also installed in the chamber. When in use, multiple plate condensers are stacked and installed. If the parallelism and verticality of the condenser itself during welding are not enough, the center of gravity of the condenser will be unstable. The condenser is prone to deformation and cracking when under pressure. The location where the enamel process is performed on the surface of the condenser is subjected to stress concentration, which will cause the enamel coating to explode. Summary of the invention

[0005] The purpose of the present invention is to solve the technical problem of low installation accuracy of the condenser sheet in the molding process in the prior art, which leads to compression deformation. A condenser sheet molding process is provided, which can improve the parallel assembly accuracy of the condenser sheet during the processing and welding process, and improve the pressure bearing capacity of the condenser sheet. The main concept is: 1. A condenser sheet forming process, comprising the following process steps: S1. Prepare the condenser parts, including two heat exchange plates, side plates and reinforcing rib plates; S2. Correct the heat exchange plate; place the heat exchange plate on the working platform and squeeze the heat exchange plate through the flattening mechanism; S3, positioning the reinforcing rib plate; marking the upper surface of the heat exchange plate to mark the installation position of the reinforcing rib plate; placing the reinforcing rib plate vertically at the marked position, and preliminarily positioning and connecting the reinforcing rib plate to the heat exchange plate by spot welding; S4, welding of the reinforcing rib plate; placing the auxiliary wood block on the top of the reinforcing rib plate, pressing the auxiliary wood block downward by the flattening mechanism to eliminate the gap between the reinforcing rib plate and the heat exchange plate, and then fully welding the reinforcing rib plate and the heat exchange plate by the welding gun; S5. Positioning the upper heat exchanger plate: After the reinforcing rib plate and the heat exchanger plate are fully welded, the flattening mechanism and the auxiliary wood block are reset, and the heat exchanger plate constituting the upper layer of the condenser plate is placed above the reinforcing rib plate and aligned with the lower heat exchanger plate; S6, welding of heat exchange plates; placing auxiliary wooden blocks on the upper heat exchange plates, squeezing the auxiliary wooden blocks downwards through a flattening mechanism to eliminate the gap between the reinforcing rib plate and the upper heat exchange plates, and then preliminarily positioning and connecting the upper heat exchange plates and the reinforcing rib plate through spot welding, and then resetting the flattening mechanism and the auxiliary wooden blocks; S7, remove the combined component formed by the reinforcing rib plate and the two heat exchange plates from the working platform, and fully weld the upper heat exchange plate and the reinforcing rib plate again; S8. Welding the combined component formed by the reinforcing rib plate and the two heat exchange plates to the side plates, and using the side plates to close the side of the combined component to form a refrigerant cavity.

[0006] This process scheme places the condenser plate parts on a work platform for processing, and then uses a flattening mechanism to press the edges of the heat exchange plate, so that the heat exchange plate attached to the positioning table of the work platform is corrected for horizontality under the extrusion of the flattening mechanism. When the two heat exchange plates that have been flattened and corrected cooperate with each other, the parallelism between the two heat exchange plates is accurate; the reinforcing rib plate is first installed on the lower heat exchange plate through pre-processing spot welding, and the gap between the reinforcing rib plate and the heat exchange plate is eliminated by the flattening mechanism, so that the reinforcing rib plate and the lower heat exchange plate are tightly fitted, so that when the upper heat exchange plate is pressed by the flattening mechanism, the upper heat exchange plate can also ensure accurate parallelism with the lower heat exchange plate during welding; in addition, the reinforcing rib plate is set between the two heat exchange plates, because the reinforcing rib plate and the heat exchange plate are tightly fitted, the weld formed at the welding position is uniform, and the enamel coating after the condenser plate is processed and formed will not explode due to uneven stress of the reinforcing rib plate.

[0007] Preferably, the preparation of the heat exchange plate in S1 comprises the following steps: S11, cutting rectangular sheets; S12, forming a stamping groove in the middle of the sheet material through a stamping process; S13, punching out two bottom holes at the bottom of the punching groove; S14. The bottom hole is processed by a stamping process to form a material channel that protrudes downward and is cylindrical.

[0008] Preferably, the working platform is used to place the condensing sheet parts to be processed; the flattening mechanism includes a frame, a power assembly and a flattening block, the power assembly is installed above the frame, the output part of the power assembly is connected to the flattening block, and the power assembly is used to provide power for the flattening block to move relative to the working platform. In the condensing sheet forming process, the condensing sheet parts are squeezed by the working platform 1 and the flattening mechanism, the flattening mechanism is installed on the working platform through the frame, and the condensing sheet parts are placed on the working platform, and the flattening block is used to squeeze the condensing sheet parts by starting the power assembly.

[0009] The second aspect of the present invention aims to solve the problem that the stamping groove formed on the heat exchange plate has a height difference during the extrusion process of the flattening mechanism, which leads to interference between the flattening mechanism and the heat exchange plate. Furthermore, an avoidance groove is provided at the bottom of the flattening block, and the flattening block is used to flatten the edge position of the condensing sheet part. By setting the avoidance groove, the stamping groove formed in the middle position of the condensing sheet part can be prevented from interfering with the flattening block; the flattening block also includes a first flattening portion and a second flattening portion, the first flattening portion is the edge position of one side of the flattening block where the avoidance groove is opened, and the second flattening portion is the bottom surface of the avoidance groove. In order to adapt to the shape of the stamping groove set on the condenser part, the flattening block of the present invention is provided with an avoidance groove at a position opposite to the stamping groove of the condenser part, so that the flattening block only flattens the edge of the condenser part, thereby improving the parallel accuracy between the heat exchange plates 101; a first flattening portion is provided on one side of the flattening block where the avoidance groove is provided, and the first flattening portion forms a rectangular frame-shaped flattening structure, and the bottom surface of the avoidance groove is provided as a second flattening portion, and the second flattening portion is a rectangular flattening structure, and the first flattening portion and the second flattening portion are respectively located at the top and bottom of the avoidance groove, so that the first flattening portion and the second flattening portion form a height difference so that different positions of the condenser part can be processed.

[0010] Preferably, the frame includes four support columns, the frame is connected to the working platform via the support columns, and the support columns are vertically mounted on the sides of the supporting platform. The frame is mounted on the working platform so that the frame and the power assembly and flattening block mounted on the frame can form an integral structure with the working platform, thereby avoiding the need to reposition the working platform and the flattening block after the installation environment changes.

[0011] The third aspect of the present invention aims to solve the technical problem that after the edge of the heat exchange plate is squeezed by the flattening block, the heat exchange plate rebounds after the flattening block is reset, resulting in flattening failure. Further, the specific steps included in S2 are: S21, placing the heat exchange plate on the positioning table, with the side of the heat exchange plate with the stamping groove facing upward, and the edge of the heat exchange plate tightly placed on the positioning table; S22, starting the power assembly, which drives the flattening block to move downward, so that the first flattening portion of the flattening block presses the edge of the heat exchange plate; S23. The edge of the heat exchange plate is clamped and shaped by the clamping pliers. After the clamping pliers are clamped, the power assembly drives the flattening block to reset upward, thereby completing the flattening, shaping and positioning of the heat exchange plate.

[0012] In this solution, after the heat exchange plate is extruded by the first flattening portion of the flattening block, the edge of the heat exchange plate remains flat under the extrusion action, and the clamping pliers are used to clamp the position of the heat exchange plate extending from the first flattening portion, so that after the flattening block is reset, the heat exchange plate can be continuously pressed by the clamping pliers to prevent the edge position from rebounding on the one hand, and on the other hand, the heat exchange plate can be positioned on the positioning table by the clamping pliers to prevent the heat exchange plate from being displaced in subsequent processes.

[0013] Preferably, the specific operation steps in S4 are: S41, after spot welding and positioning of the plurality of reinforcing rib plates are completed, a plurality of auxiliary wooden blocks are placed on the reinforcing rib plates; S42, starting the power assembly to drive the flattening block to move downward, the avoidance groove of the flattening block accommodates a plurality of auxiliary wooden blocks, and the second flattening part applies a force to the auxiliary wooden blocks, so that the gap at the connection position between the reinforcing rib plate and the heat exchange plate is eliminated; S43, and then fully weld the reinforcing rib plate and the heat exchange plate using a welding gun, so that the heat exchange plate and the reinforcing rib plate are vertically connected.

[0014] In this solution, an auxiliary wooden block is placed on the reinforcing rib plate for preliminary vertical positioning, and the auxiliary wooden block is squeezed by the second flattening part. After the reinforcing rib plate is pressed, the gap between the heat exchange plate and the reinforcing rib plate is eliminated, and under the squeezing action of the flattening block, the reinforcing rib plate and the heat exchange plate are fully welded, so that the reinforcing rib plate and the heat exchange plate are closely fitted and the weld is uniform, and the ends of the multiple reinforcing rib plates away from the lower heat exchange plate are also kept flat, which is convenient for the installation of the upper heat exchange plate.

[0015] Preferably, the extension length of the auxiliary wood block is arranged perpendicularly to the reinforcing rib plate, and the length of the auxiliary wood block is smaller than the avoidance groove. The auxiliary wood block is arranged perpendicularly to the reinforcing rib plate, so that the auxiliary wood block can be placed stably on the reinforcing rib plate, and the avoidance groove can accommodate the auxiliary wood block, so that the surface of the auxiliary wood block can be completely fitted with the second flattening part of the avoidance groove, which can avoid the interference between the auxiliary wood block and the first flattening part, resulting in the auxiliary wood block being pressed on one side and warping, affecting the pressing effect.

[0016] The third aspect of the present invention aims to solve the technical problem of difficulty in aligning materials between two heat exchange plates. Further, the specific operation steps in S5 are: S51, determining the orientation between the upper heat exchange plate and the heat exchange plate welded with the reinforcing rib plate through the material channel; S52, the cylindrical material channels are arranged opposite to each other, the convex surface of the stamping groove of the upper heat exchange plate is facing downward, and the material channels of the two heat exchange plates arranged opposite to each other are arranged coaxially so that the two heat exchange plates are aligned; S53, placing an auxiliary wooden block in the stamping groove of the upper heat exchange plate, starting the power assembly, so that the second flattening part of the flattening block applies force to the auxiliary wooden block to eliminate the gap between the upper heat exchange plate and the reinforcing rib plate; S54. Spot weld the upper heat exchange plate and the reinforcing rib plate to ensure the parallelism between the two heat exchange plates and the verticality between the two heat exchange plates and the reinforcing rib plate.

[0017] This solution can determine and align the orientation of the two heat exchange plates through the material channel. Since two material channels are provided on the heat exchange plate, the two heat exchange plates are placed in the direction in which the material channels are opened, and are aligned according to the two groups of material channels between the two heat exchange plates, so that the material channels between the two heat exchange plates are coaxially arranged, and the aligned heat exchange plates are fully welded.

[0018] Preferably, the side plates in S8 are bent multiple times by a heat bending process, so that the side plates form a rectangular sealing frame structure between the heat exchange plates.

[0019] The beneficial effects of the present invention are as follows: by placing the condensing plate parts on a working platform for processing, and then pressing the edges of the heat exchange plates by a flattening mechanism, the heat exchange plates attached to the positioning platform of the working platform are corrected for horizontality under the extrusion of the flattening mechanism, and when the two heat exchange plates after flattening correction cooperate with each other, the parallelism between the two heat exchange plates is accurate; the reinforcing rib plate is first installed on the lower heat exchange plate by pre-processing spot welding, and the gap between the reinforcing rib plate and the heat exchange plate is eliminated by a flattening mechanism, so that the reinforcing rib plate and the lower heat exchange plate are tightly fitted, so that when the upper heat exchange plate is pressed by the flattening mechanism, the upper heat exchange plate can also ensure accurate parallelism with the lower heat exchange plate during welding; in addition, the reinforcing rib plate is arranged between the two heat exchange plates, and because the reinforcing rib plate and the heat exchange plate are tightly fitted, the weld formed at the welding position is uniform, and the enamel coating after the condensing plate is processed and formed will not burst due to uneven stress of the reinforcing rib plate.

Weld the combined component formed by the reinforcing rib plate 103 and the two heat exchange plates 101 to the side plate 102, and use the side plate 102 to close the side of the combined component to form a refrigerant cavity.

[0031] In this process scheme, the condenser plate parts are placed on the working platform 1 for processing, and then the edges of the heat exchange plate 101 are pressed tightly by the flattening mechanism, so that the heat exchange plate 101 attached to the positioning platform 11 of the working platform 1 is corrected for horizontality under the extrusion of the flattening mechanism. When the two heat exchange plates 101 after flattening correction are matched with each other, the parallelism between the two heat exchange plates 101 is accurate; the reinforcing rib plate 103 is first installed on the lower heat exchange plate 101 by pre-processing spot welding, and the reinforcing rib plate 103 and the heat exchange plate 10 are eliminated by the flattening mechanism. 1, so that the reinforcing rib plate 103 and the lower heat exchange plate 103 are closely fitted, so that when the upper heat exchange plate 101 is pressed by the flattening mechanism, the upper heat exchange plate 101 can also ensure precise parallelism with the lower heat exchange plate 101 during welding; in addition, the reinforcing rib plate 103 is arranged between the two heat exchange plates 101, because the reinforcing rib plate 103 and the heat exchange plate 101 are closely fitted, the weld formed at the welding position is uniform, and the enamel coating after the condenser sheet is processed and formed will not cause porcelain explosion due to uneven stress of the reinforcing rib plate 103.

[0036] Among them, the sheet material is placed on the flanging die, and the sheet material is pressed against the upper flanging die by a pressing tool. The flanging shaping punch moves downward. A stamping guide hole with an inner diameter larger than the bottom hole is provided in the middle of the flanging die. The flanging shaping punch is a cylindrical part that can cooperate with the stamping guide hole. The flanging shaping punch stamps the sheet material so that the edge of the bottom hole is squeezed and deformed, so that a cylindrical material channel 105 is formed along the stamping guide hole of the bottom hole.

[0037] The side plates 102 are installed on the sides of the two heat exchange plates 101 to form a refrigerant cavity. Example 3

[0038] like Figure 1-Figure 4As shown, the flattening block 4 of this embodiment is provided with an avoidance groove 41 at the bottom, and the flattening block 4 is used to flatten the edge position of the condensing sheet part 100. By setting the avoidance groove 41, the stamping groove formed in the middle position of the condensing sheet part 100 can not interfere with the flattening block 4; the flattening block 4 also includes a first flattening portion 42 and a second flattening portion 43, the first flattening portion 42 is the edge position of one side of the flattening block 4 where the avoidance groove 41 is opened, and the second flattening portion 43 is the bottom surface of the avoidance groove 41.

[0039] In order to adapt to the shape of the stamping groove set on the condensing sheet part, the flattening block of the present invention is provided with an avoidance groove at a position opposite to the stamping groove of the condensing sheet part, so that the flattening block only flattens the edge of the condensing sheet part, thereby improving the parallel accuracy between the heat exchange plates 101; a first flattening portion 42 is provided on one side of the flattening block 4 with the avoidance groove 41, and the first flattening portion 42 forms a rectangular frame-shaped flattening structure, and the bottom surface of the avoidance groove 41 is provided with a second flattening portion 43, and the second flattening portion 43 is a rectangular flattening structure, and the first flattening portion 42 and the second flattening portion 43 are respectively located at the top and bottom of the avoidance groove 41, so that the first flattening portion 42 and the second flattening portion 43 form a height difference so that different positions of the condensing sheet part 100 can be processed.

[0040] The work platform 1 is provided with a positioning platform 11, which is arranged in the middle of the work platform 1. The positioning platform 11 is arranged parallel to and opposite to the flattening block 4.

[0041] Preferably, the frame 2 includes four support columns 21 , and the frame 2 is connected to the working platform 1 via the support columns 21 , and the support columns 21 are vertically installed on the sides of the supporting platform 1 .

[0042] The frame 1 is installed on the working platform 1, so that the frame 2 and the power assembly 3 and the flattening block 4 installed on the frame 2 can form an integral structure with the working platform 1, avoiding the need to reposition the working platform 1 and the flattening block 4 after the forming auxiliary equipment is transferred. Example 4

[0043] like Figure 1-Figure 2 As shown, S2 of this embodiment includes the following specific steps: S21, placing the heat exchange plate 101 on the positioning platform 11, with the side of the heat exchange plate 101 with the stamping groove 104 facing upward, and the edge of the heat exchange plate 101 closely attached to the positioning platform 11; S22, starting the power assembly 3, the power assembly 3 drives the flattening block 4 to move downward, so that the first flattening portion 42 of the flattening block 4 presses the edge of the heat exchange plate 101; S23, the edge of the heat exchange plate 101 is clamped and shaped by the clamping pliers. After the clamping pliers are clamped, the power assembly 3 drives the flattening block 4 to reset upward, thereby completing the flattening, shaping and positioning of the heat exchange plate 101.

[0044] In this solution, after the heat exchange plate 101 is extruded by the first flattening portion 42 of the flattening block 4, the edge of the heat exchange plate 101 remains flat under the extrusion, and the clamping pliers are used to clamp the position of the heat exchange plate 101 extending from the first flattening portion 42, so that after the flattening block 4 is reset, the heat exchange plate 101 can be continuously pressed by the clamping pliers to avoid rebound of the edge position on the one hand, and can be positioned on the positioning platform 11 by the clamping pliers on the other hand, so as to avoid displacement of the heat exchange plate 101 caused by subsequent processes. Example 5

[0045] Figures S3 and Figure 5 As shown, the specific operation steps in this embodiment S4 are: S41, after spot welding and positioning of the plurality of reinforcing rib plates 104 is completed, a plurality of auxiliary wood blocks 5 are placed on the reinforcing rib plates 104; S42, start the power assembly 3 to drive the flattening block 4 to move downward, the avoidance groove 41 of the flattening block 4 accommodates a plurality of auxiliary wooden blocks 5, and the second flattening part 43 applies a force to the auxiliary wooden blocks 5, so that the gap at the connection position between the reinforcing rib plate 104 and the heat exchange plate 101 is eliminated, S43, fully weld the reinforcing rib plate 103 and the heat exchange plate 101 by using a welding gun, so that the heat exchange plate 101 and the reinforcing rib plate 103 are vertically connected.

[0046] In this embodiment, an auxiliary wood block 5 is placed on the reinforcing rib plate 103 that is initially vertically positioned, and the auxiliary wood block 5 is pressed by the second flattening portion 43. After the reinforcing rib plate 103 is pressed, the gap between the heat exchange plate 101 is eliminated, and under the pressing action of the flattening block 4, the reinforcing rib plate 103 and the heat exchange plate 101 are fully welded, so that the reinforcing rib plate 103 and the heat exchange plate 101 are closely fitted and the weld is uniform, and the ends of the plurality of reinforcing rib plates 103 away from the lower heat exchange plate 101 are also kept flat, which is convenient for the installation of the upper heat exchange plate 101.

[0047] The extended length of the auxiliary wood block 5 of this embodiment is arranged perpendicularly to the reinforcing rib plate 103, and the length of the auxiliary wood block 5 is smaller than the avoidance groove 41. The auxiliary wood block 5 is arranged perpendicularly to the reinforcing rib plate 103, so that the auxiliary wood block 5 can be placed stably on the reinforcing rib plate 103, and the avoidance groove 41 can accommodate the auxiliary wood block 5, so that the surface of the auxiliary wood block 5 can be completely fitted with the second flattening portion 43 of the avoidance groove 41, and the interference between the auxiliary wood block 5 and the first flattening portion 42 can be avoided, resulting in the auxiliary wood block being pressed on one side and warping, which affects the pressing effect.

[0048] The height of the auxiliary wood block 5 is set higher than the avoidance groove 41, so that the auxiliary wood block 5 can reserve operating space for the welding gun to extend and weld. Example 6

[0049] like Figure 4 As shown, the specific operation steps in S5 of this embodiment are: S51, determining the orientation between the upper heat exchange plate 101 and the heat exchange plate 101 welded with the reinforcing rib plate 103 through the material channel 105; S52, the cylindrical material channels 105 are arranged opposite to each other, the convex surface of the stamping groove 104 of the upper heat exchange plate 101 faces downward, and the material channels 105 of the two heat exchange plates 101 arranged opposite to each other are arranged coaxially, so that the two heat exchange plates 101 are aligned; S53, placing the auxiliary wood block 5 in the stamping groove 104 of the upper heat exchange plate 101, starting the power assembly 3, so that the second flattening portion 43 of the flattening block 4 applies force to the auxiliary wood block 5, eliminating the gap between the upper heat exchange plate 101 and the reinforcing rib plate 103; S54, spot welding the upper heat exchange plate 101 and the reinforcing rib plate 103 to ensure the parallelism between the two heat exchange plates 101 and the verticality between the two heat exchange plates 101 and the reinforcing rib plate 103.

[0050] In this embodiment, the orientation of the two heat exchange plates 101 can be determined and aligned through the material channel 105. Since two material channels 105 are provided on the heat exchange plate 101, the two heat exchange plates 101 are placed in the direction in which the material channels are opened, and the two groups of material channels 105 between the two heat exchange plates 101 are aligned so that the material channels 105 between the two heat exchange plates 101 are coaxially arranged, and the aligned heat exchange plates 101 are fully welded.

[0051] In this embodiment, the material channels 105 between the two heat exchange plates 101 can be connected when aligned, and the height at which the two material channels 105 start to extend relative to the plane of the heat exchange plates 101 is set to be equal to the height of the reinforcing rib plate 103, so that when the upper heat exchange plate 101 is placed on the reinforcing rib plate 103 welded to the lower heat exchange plate 101, the material channels 105 of the heat exchange plates 101 can be aligned and abutted.

[0052] In addition, in this embodiment, since the channel for the flow of heat exchange medium is connected by the cylindrical material channels 105 on the two heat exchange plates 101, the material holes 105 on the heat exchange plates 101 are integrally formed by a stamping die, so that the heat exchange plates 101 will not have pipes welded at the openings on their surfaces like traditional channels, thereby avoiding the enamel cracking at the welding position on the surface of the pipe after the enamel coating is sintered on the surface of the heat exchange plate 101; the sealing and aesthetics of the material channel 105 are improved.

[0053] In this embodiment, the upper heat exchange plate 101 and the reinforcing rib plate 103 are spot welded. After the parallelism between the two heat exchange plates 101 and the verticality between the two heat exchange plates 101 and the reinforcing rib plate 103 are met, the clamping pliers acting on the edge of the lower heat exchange plate 101 in S23 are removed, so that the condenser plate parts after positioning welding are removed from the positioning platform 11, and then full welding is performed between the upper heat exchange plate 101 and the reinforcing rib plate 103. Example 7

[0054] like Figure 6 As shown, the side plate 102 in S8 of this embodiment is bent multiple times through a thermal bending process, so that the side plate 102 forms a rectangular sealing frame structure between the heat exchange plates 101 .

[0055] The side plate 102 of this embodiment can seal the edge of the heat exchange plate 101, and the height of the side plate 102 is the height of the gap between the edge positions of the heat exchange plate 101. The length of the side plate 102 is set to be able to cover the circumference of the side edge of the heat exchange plate 101, so that the side plate 102 can seal the refrigerant layer formed by the heat exchange plate 101. When the length of the side plate 102 is too long, it can be adjusted to a suitable position for sealing by cutting. The height of the side plate 102 is adapted to the gap position between the side positions of the heat exchange plate 101, so that the parallelism between the heat exchange plates 101 will not be affected when the side plate 102 is welded and connected between the heat exchange plates 101.

[0056] A side panel with a certain length is bent by high-temperature heating, so that the side panel 102 can form multiple bending parts after multiple bending, and the bending parts are respectively welded to the side edges of two parallel rectangular heat exchange plates. The bent side panels form a closed frame structure, and the vertical bends of the closed frame structure always maintain a smooth integrated connection.

[0057] The bending process of this embodiment adopts a thermal bending process, which heats the metal side plate 102 to a certain temperature to make it soft and easy to bend, and then applies a certain force to bend it. After cooling, the side plate 102 maintains the required bend.

[0058] The side plates 102 are arranged between the heat exchange plates 101. The side plates 102 can be used to provide support for the heat exchange plates 101. The side plates 102 are respectively abutted against the edge positions of the surfaces of the two heat exchange plates 101 that are relatively arranged, so that during the actual use of the condensing sheet formed by the heat exchange plates 101 and the side plates 102, the side plates 102 can prevent the edge positions of the heat exchange plates 101 from collapsing or cracking.

[0059] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
