Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a heat exchange device and water treatment equipment. Background Technology

[0002] Plate heat exchangers typically have multiple layers of heat exchange baffles inside. The heat exchange medium and water, which need to exchange energy with the heat exchange medium, flow between the different heat exchange baffles, and energy exchange occurs through the baffles. However, the heat exchange baffles are usually made by stamping, which can easily deform over time, causing the heat exchanger to malfunction or reduce its heat exchange efficiency. Utility Model Content

[0003] To address the problem that existing heat exchange baffles are typically manufactured using a stamping process, resulting in significant internal stress and easy deformation over time, which leads to the heat exchanger failing to exchange heat properly or experiencing reduced heat exchange efficiency, this invention provides a heat exchange device and water treatment equipment.

[0004] This application provides a heat exchange device, wherein the heat exchange device has mutually isolated water flow channels and heat exchange medium channels inside, and the heat exchange device includes: Multiple heat exchange baffles are stacked sequentially, and the outer edges of the multiple heat exchange baffles are stacked and welded together. A water flow channel or a heat exchange medium channel is formed between adjacent heat exchange baffles. The sides of the plurality of heat exchange baffles are recessed in the same direction, such that the heat exchange baffle includes a bottom and a side portion, the side portion being inclined relative to the bottom and surrounding the edge disposed on the bottom; Along the concave direction of the heat exchange baffle, in any two adjacent heat exchange baffles, the heat exchange baffle of the adjacent outer layer is defined as the outer layer plate, and the heat exchange baffle of the inner layer is defined as the inner layer plate, and the inner side of the open end of the outer layer plate elastically abuts against the outer side of the open end of the inner layer plate.

[0005] In some embodiments, on the same cutting plane along the recessed direction of the heat exchange device, the relative distance between the inner sides of the open ends of the side portion of the outer layer plate is L1, and the relative distance between the outer sides of the open ends of the side portion of the heat exchange partition plate adjacent to the outer layer plate is L2, wherein L1 < L2 when the outer layer plate is separated from the inner layer plate.

[0006] In some embodiments, the side of the partition is recessed to form a cavity, and one end of the side away from the bottom is bent outward toward the outside of the cavity to form a curved portion and an edge portion for welding, the edge portion being parallel to the bottom.

[0007] In some embodiments, on the same cutting plane along the concave direction of the heat exchange device, a plurality of heat exchange baffles are arranged along the concave direction, and the relative spacing between the inner sides of the open ends of the side portions of the preceding heat exchange baffles is smaller than the relative spacing between the outer sides of the open ends of the side portions of the subsequent heat exchange baffles.

[0008] In some embodiments, the inner and outer surfaces of the bottom are formed with recesses and protrusions, the recesses and protrusions are spaced apart, the recesses of adjacent bottoms are arranged opposite each other to form the water flow channel or the heat exchange medium channel, and the protrusions of adjacent bottoms abut against each other. The depth of the protrusion on the inner side of the bottom of the outer layer plate is set to M1, and the protrusion distance of the bottom of the heat exchange baffle adjacent to the outer layer plate is set to M2. When the outer layer plate is separated from the inner layer plate, M1 < M2.

[0009] In some embodiments, on the same cutting plane along the concave direction of the heat exchange device, a plurality of heat exchange baffles are arranged along the concave direction, wherein the depth of the protrusion on the inner side of the bottom of the previous heat exchange baffle is less than the protrusion distance of the bottom of the subsequent heat exchange baffle.

[0010] In some embodiments, the recess and the convex portion of the bottom are formed by stamping, with the convex portion on the outer side of the bottom corresponding to the recess on the inner side of the bottom, and the recess on the outer side of the bottom corresponding to the convex portion on the inner side of the bottom.

[0011] In some embodiments, along the recessed direction, the thickness of the outermost heat exchange baffle and the innermost heat exchange baffle is greater than the thickness of the heat exchange baffle between them.

[0012] In some embodiments, the heat exchange device further includes a clamping member, wherein a plurality of heat exchange baffles are stacked to form a heat exchange body, and the clamping member is disposed on the outside of the heat exchange body to clamp the heat exchange body.

[0013] This application provides a water treatment device, including the aforementioned heat exchanger.

[0014] Compared with the prior art, the heat exchange device provided by this utility model has the following advantages: Through the design of this application, after the outer edges of each heat exchange baffle are welded and fixed, since the inner dimension of the open end of the outer layer plate is smaller than the outer dimension of the open end of the inner layer plate, the outer layer plate will clamp the inner layer plate, which will clamp and fix each inner layer plate, making it less likely for each inner layer plate to deform during use, making the internal structure of the heat exchange device more stable, and the heat exchange effect can be well guaranteed.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2 , Figure 3 The heat exchange device shown has internally isolated water flow channels and heat exchange medium channels. The heat exchange device provided in this application includes a plurality of sequentially stacked heat exchange baffles 100, with the outer edges of the baffles 100 stacked and sealed. Water flow channels or heat exchange medium channels are formed between adjacent baffles 100. It is understood that the outer edges of the aforementioned plurality of heat exchange baffles 100 can be sealed by stacking and welding, so that the intervals between each heat exchange baffle 100 are relatively independent, thereby forming the aforementioned water flow channels and heat exchange medium channels.

[0024] like Figure 2 , Figure 3 As shown, for ease of understanding, the basic structure of the heat exchange device provided in this application is further explained below: It can be understood that the intervals formed between the various heat exchangers are arranged sequentially. Along the same arrangement direction, each interval is numbered. Odd-numbered intervals are designated as water flow channels, and even-numbered intervals are designated as heat exchange medium channels. Corresponding connecting ports are then provided on the outside of the heat exchange device to connect the odd-numbered intervals to form water flow channels and the even-numbered intervals to form heat exchange medium channels. This is the basic structure of the heat exchange device provided in this application.

[0025] like Figure 3 The sides of the plurality of heat exchange baffles 100 are recessed in the same direction, such that each heat exchange baffle 100 includes a bottom 11 and a side portion 12. The side portion 12 is inclined relative to the bottom 11 and surrounds the edge of the bottom 11. Along the recessed direction X of the heat exchange baffle 100, in any two adjacent heat exchange baffles 100, the adjacent outer heat exchange baffle 100 is defined as the outer layer plate 101, and the inner heat exchange baffle 100 is defined as the inner layer plate. The inner side of the open end of the outer layer plate 101 elastically abuts against the outer side of the open end of the inner layer plate. With this arrangement, after the outer edges of each heat exchange baffle are welded, the outer layer plate can clamp and fix the inner layer plate, making it less likely for the inner layer plates to deform during use.

[0026] The technical details of each component will be introduced below.

[0027] In some implementations, such as Figure 3 , Figure 4 As shown, on the same cutting plane along the concave direction X of the heat exchange device, the relative distance between the inner sides of the open ends of the side portions 12 of the outer layer plate 101 is L1, and the relative distance between the outer sides of the open ends of the side portions 12 of the heat exchange baffles 100 adjacent to the outer layer plate 101 is L2. When the outer layer plate 101 is separated from the inner layer plate, L1 < L2. It can be understood that, through the above design, due to the above dimensional relationship, the outer edge of the outer layer plate 101 in its natural state cannot overlap with the outer edge of the inner layer plate. Therefore, in practical applications, when welding and fixing the outer edges of each heat exchange baffle 100, it is necessary to apply pressure to the outer layer plate 101, so that the open ends of the outer layer plate 101 undergo elastic deformation under the extrusion action with the outer side of the inner layer plate (the heat exchange baffle 100 is a thin plate structure, and elastic deformation can occur during extrusion), making the size of the open ends of the outer layer plate larger, overlapping with the outer edge of the inner layer plate, and then welding is performed. After welding, the outer layer plate 101 will tend to return to its original size, which will clamp the inner layer plate and fix each inner layer plate. This makes the inner layer plate less prone to deformation during use, making the internal structure of the heat exchange device more stable and ensuring a good heat exchange effect.

[0028] In some implementations, such as Figure 3 As shown, the side of the heat exchange baffle 100 is recessed to form a chamber. The end of the side portion 12 away from the bottom 11 bends outward from the chamber to form a bent portion 13 and an edge portion 14 for welding. The edge portion 14 is parallel to the bottom 11. It is understood that in practical applications, sufficient welding surface needs to be reserved when welding the edge portions 14 of each heat exchange baffle 100. Through the above design, the parallel arrangement of the edge portions 14 of each heat exchange baffle 100 provides sufficient welding surface during the welding process, ensuring the strength of the weld. In addition to the above technical effects, the parallel arrangement of the edge portions 14 also makes welding more convenient.

[0029] Understandably, the more firmly the outer edge of the heat exchange baffle 100 is welded, the more tightly the outer plate 101 can clamp the inner plate, which helps to improve the stability of the internal structure of the heat exchange device.

[0030] In some other implementations, such as Figure 3As shown, both the inner and outer sides of the curved portion 13 are configured with arc-shaped structures 131. The arc-shaped structures 131 can act as sliding guides at the outer edges of each heat exchanger 100 during the pressing and welding process. The outer layer plate 101 can also slide through the arc-shaped structures 131 to undergo a predetermined deformation to clamp the inner layer plate. In addition to the above-mentioned technical effects, the arc-shaped structures 131 can also prevent damage to each heat exchanger 100 during the clamping process, thus protecting the heat exchanger 100.

[0031] In some embodiments, on the same cross-sectional plane along the concave direction X of the heat exchange device, a plurality of heat exchange baffles 100 are arranged along the concave direction X, and the relative spacing between the inner sides of the open ends of the side portions 12 of the preceding heat exchange baffle 100 is smaller than the relative spacing between the outer sides of the open ends of the side portions 12 of the following heat exchange baffle 100. See also... Figure 3 , Figure 5 By understanding the above design, each heat exchange baffle 100 can be pressed together step by step. It is not only due to the pressing effect of the outer plate 101, but also the inner plates can be pressed together, which further improves the stability of the internal structure of the heat exchange device.

[0032] In some implementations, such as Figure 4 As shown, the inner and outer surfaces of the aforementioned bottom 11 have recesses 111 and protrusions 112, which are spaced apart. Recesses 111 and protrusions 112 on adjacent bottom 11s are arranged opposite each other to form water flow channels or heat exchange medium channels, while protrusions 112 on adjacent bottom 11s abut against each other. It can be understood that the alternating arrangement of recesses 111 and protrusions 112 prevents adjacent heat exchange baffles 100 from being completely fitted together, maintaining the stability of the water flow channels and heat exchange medium channels. Simultaneously, the recesses 111 and protrusions 112 can increase the surface area of ​​the heat exchange baffles 100, thereby improving the heat exchange efficiency of the heat exchange device.

[0033] Please continue reading. Figure 4 The depth of the protrusion 112 on the inner side of the bottom 11 of the outer layer plate 101 is set to M1, and the protrusion distance of the bottom 11 of the heat exchange baffle 100 adjacent to the outer layer plate 101 is set to M2. When the outer layer plate 101 is separated from the inner layer plate, M1 < M2. Through the above design, after the outer edge of the outer layer plate 101 is welded to the outer edge of the inner layer plate, due to the above dimensional relationship, the outer layer plate 101 will undergo elastic deformation, generating a clamping force on the inner layer plate along the arrangement direction of each heat exchange baffle 100 (consistent with the recessed direction X), further enhancing the stability of the internal structure of the heat exchange device.

[0034] For further information, please refer to Figure 4 , Figure 5To understand this, on the same cutting plane along the concave direction X of the heat exchange device, multiple heat exchange baffles 100 are arranged along the concave direction X. The depth of the protrusion 112 on the inner side of the bottom 11 of the previous heat exchange baffle 100 is less than the protrusion distance of the bottom 11 of the subsequent heat exchange baffle 100. Through the above design, the inner plates can also form a mutually pressing state along the arrangement direction of each heat exchange baffle 100 (consistent with the concave direction X). Not only does it rely on the pressing of the outer plate 101, but the inner plates also have a pressing and fixing effect on each other, further enhancing the stability of the internal structure of the heat exchange device.

[0035] In some implementations, such as Figure 3 , Figure 4 , Figure 5 As shown, the recess 111 and protrusion 112 of the bottom 11 are formed by stamping. The protrusion 112 on the outer side of the bottom 11 corresponds to the recess 111 on the inner side of the bottom 11, and the recess 111 on the outer side of the bottom 11 corresponds to the protrusion 112 on the inner side of the bottom 11. It can be understood that by forming the recess 111 and protrusion 112 through the stamping process, each heat exchange baffle 100 can undergo appropriate elastic deformation during the clamping and extrusion process.

[0036] In some implementations, such as Figure 3 , Figure 4 As shown, along the concave direction X, the thickness of the outermost heat exchange baffle 100 and the innermost heat exchange baffle 100 is greater than the thickness of the heat exchange baffle 100 between them. Through the above design, the outer plate 101 can have stronger structural strength, and can clamp the inner plate more firmly and stably.

[0037] In some embodiments, the heat exchange device provided in this application further includes a clamping member. Multiple heat exchange baffles 100 are stacked to form a heat exchange body, and the clamping member is disposed on the outside of the heat exchange body to clamp it. Through this design, the clamping member can clamp the heat exchange body from the outside, thereby assisting the outer layer plate 101 in clamping the inner layer plate by applying inward pressure to the outer layer plate 101.

[0038] This application provides a water treatment device, including the aforementioned heat exchanger. This can improve the performance and lifespan of the heat exchanger in the water treatment equipment.
