Description

Technical Field

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

[0004] This application provides a heat exchanger with mutually isolated water flow channels and medium channels inside. The heat exchanger includes multiple heat exchange baffles, which are arranged sequentially along a first direction. The water flow channels or medium channels are formed between adjacent heat exchange baffles, and the outer edges of the multiple heat exchange baffles are stacked and sealed. The heat exchange baffles of the adjacent outer layer are defined as outer layer plates, and the heat exchange baffles of the inner layer are defined as inner layer plates. The mechanical strength and deformation resistance of the material or structure of the outer layer plate are greater than those of the inner layer plate. The outer layer plate clamps the inner layer plate.

[0005] In some embodiments, the plurality of heat exchange baffles include a first baffle and a second baffle, wherein the material of the first baffle has greater mechanical strength and resistance to deformation than that of the second baffle; Along the first direction, the first partition and the second partition are alternately spaced, with the second partition sandwiched between the two first partitions.

[0006] In some embodiments, the heat exchange baffle is recessed inward to form a chamber on one side and a protrusion on the other side; When the outer edges of each heat exchange baffle are stacked and welded, along the concave direction of the heat exchange baffle, the protrusion of the previous heat exchange baffle is inserted into the cavity of the next heat exchange baffle to form a multi-layered stacked structure, and the inner sidewall of the cavity of the next heat exchange baffle abuts against the outer sidewall of the protrusion of the previous heat exchange baffle.

[0007] In some embodiments, the heat exchange baffle has a recessed side forming a bottom and a side portion surrounding the outer edge of the bottom. The side portions and the bottom of each heat exchange baffle are stacked sequentially to form the multi-layer nested structure, and the side portions are inclined outward relative to the bottom.

[0008] In some embodiments, a plurality of heat exchange baffles are arranged along the first direction, and among the plurality of heat exchange baffles, the two outermost heat exchange baffles are defined as outer baffles, and the heat exchange baffle between the two outer baffles is defined as an inner baffle. A clamping space for clamping the inner layer is formed between the two outer layer plates; When the inner layer plate is clamped in the clamping space, the inner layer plate undergoes elastic deformation toward the interior of the clamping space.

[0009] In some implementations, the thickness of the two outermost heat exchange baffles is greater than the thickness of the inner heat exchange baffles.

[0010] In some embodiments, a welding portion is further provided in the middle of the side of the heat exchange baffle, the welding portion being used to weld and fix it to the welding portion of the adjacent heat exchange baffle.

[0011] In some embodiments, the heat exchange baffle is stamped with a corrugated structure on both sides, the corrugated structure including alternating crests and troughs, the crests of adjacent heat exchange baffles abutting each other, and the troughs of the corrugated structure forming the water flow channel or the medium channel.

[0012] In some embodiments, the heat exchange baffle includes a left portion and a right portion symmetrically distributed along its symmetry line, both the left portion and the right portion being provided with the corrugated structure, the crests of the left portion and the right portion being inclined relative to the symmetry line of the heat exchange baffle and being symmetrical to each other; The troughs of the left and right portions are also inclined relative to the symmetry line of the heat exchange baffle and are symmetrical to each other.

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

[0014] Compared with existing technologies, the heat exchanger provided by this utility model has the following advantages: It defines the heat exchange baffles of adjacent outer layers as outer plates and the heat exchange baffles of inner layers as inner plates. The outer plates have greater mechanical strength and resistance to deformation than the inner plates, and they clamp the inner plates tightly. Because the outer plates have higher mechanical strength and resistance to deformation than the inner plates, they can provide a better clamping effect, helping the inner plates resist their own internal stress and preventing deformation during use. By maintaining the stability of the internal structure of the heat exchanger, the heat exchange efficiency is guaranteed. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0020] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. 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 4 The heat exchanger shown has an internally isolated water flow channel 001 and a medium channel 002. It should be noted that the water flow channel 001 is used for the flow of water that needs to be heated or cooled, and the medium channel 002 is used for the flow of a heat exchange medium used to heat or cool the water. This heat exchange medium can be a liquid such as water or oil.

[0024] Please refer to it again. Figure 2 , Figure 4 The heat exchanger includes multiple heat exchange baffles 100, which are arranged sequentially along a first direction. A water flow channel 001 or a medium channel 002 is formed between adjacent heat exchange baffles 100. The outer edges of the multiple heat exchange baffles 100 are stacked and sealed (in practical applications, the outer edges of the multiple heat exchange baffles can be sealed by welding). In short, the water flow channel 001 and the medium channel 002 are the gaps between two heat exchange baffles 100.

[0025] Please see Figure 2 , Figure 4For ease of explanation of the technical solution of this application, the heat exchange baffle 100 of the adjacent outer layer is defined as the outer layer plate 101, and the heat exchange baffle 100 of the inner layer is defined as the inner layer plate 102. The mechanical strength and deformation resistance of the material or structure of the outer layer plate 101 are greater than those of the inner layer plate 102, and the outer layer plate 101 clamps the inner layer plate 102.

[0026] Specifically, the outer layer plate 101 can be made of titanium plate or nickel-based alloy plate, which has higher hardness and deformation resistance than the inner layer plate 102, and also has good thermal conductivity. The outer edges of the outer layer plate 101 and the inner layer plate 102 can be sealed together by welding. It is understood that the outer edges of the outer layer plate 101 and the inner layer plate 102 need to be pre-pressed during welding (see [reference needed]). Figure 2 , Figure 4 (For understanding) the outer edges are overlapped. During the pre-compression process, the outer layer plate 101 undergoes appropriate deformation, clamping the inner layer plate 102. After the outer edges of the outer layer plate 101 and the inner layer plate 102 are welded together, the outer layer plate 101 continues to clamp the inner layer plate 102. Through the above design, since the outer layer plate 101 has stronger mechanical strength and deformation resistance than the inner layer plate 102, it can provide a better clamping effect on the inner layer plate 102, helping the inner layer plate 102 resist its own internal stress, thereby preventing the inner layer plate 102 from deforming during use. By maintaining the stability of the internal structure of the heat exchanger, the heat exchange efficiency of the heat exchanger is guaranteed.

[0027] It is understood that in some other embodiments, the outer layer 101 can also enhance its mechanical strength and resistance to deformation by increasing its thickness. That is, the thickness of the outer layer 101 is greater than that of the inner layer 102. This design can also achieve the above-mentioned technical effects. In addition to the above technical solutions, the outer layer 101 can also enhance its mechanical strength and resistance to deformation by providing a deformation-resistant structure. For example, in some embodiments, the outer layer 101 has reinforcing ribs on its sides (the reinforcing ribs are an example of the above-mentioned deformation-resistant structure). The reinforcing ribs can effectively enhance the mechanical strength and resistance to deformation of the plate-like structure, thus achieving the goal that the mechanical strength and resistance to deformation of the outer layer 101 are stronger than that of the inner layer 102, thereby achieving the above-mentioned technical effects.

[0028] The technical details of each component will be introduced below.

[0029] In some implementations, such as Figure 4 , Figure 5As shown, the plurality of heat exchange baffles 100 include a first baffle 11 and a second baffle 12. The mechanical strength and deformation resistance of the material of the first baffle 11 are greater than those of the second baffle 12. That is, the first baffle 11 can be made of titanium plate or nickel-based alloy plate. Along the aforementioned first direction, the first baffle 11 and the second baffle 12 are alternately arranged, with the second baffle 12 sandwiched between two first baffles 11. For ease of explanation, the first baffle 11 is temporarily set as titanium plate below, but this does not limit the scope of protection of this application. It is understood that through the above design, each heat exchange baffle 100 with lower material hardness is individually clamped by a titanium plate. Obviously, the individual clamping scheme can better resist the internal stress of the heat exchange baffle 100, and thus better maintain the stability of the internal structure of the heat exchanger.

[0030] In some embodiments, the second partition 12 is a silver alloy plate. Alternatively, in other embodiments, at least one of the surfaces of the first partition 11 and the second partition 12 is plated with metallic silver. The design in both of these embodiments allows the heat exchange partition 100 to release silver elements into the water flow channel 001 and the medium channel 002, thereby achieving sterilization.

[0031] In some implementations, such as Figure 4 , Figure 5 As shown, the side of the heat exchange baffle 100 is recessed inward, forming a chamber 01 on one side and a protrusion 02 on the other side. The chamber 01 and the protrusion 02 are formed in pairs. The heat exchange baffle 100 is a plate-like structure. If its side is recessed inward, it will inevitably cause the other side to bulge.

[0032] Please refer to it again. Figure 4 , Figure 5 When the outer edges of each heat exchange baffle 100 are stacked and welded, along the concave direction of the heat exchange baffle 100, the protrusion 02 of the previous heat exchange baffle 100 is inserted into the chamber 01 of the next heat exchange baffle 100 to form a multi-layered stacked structure. The inner wall of the chamber 01 of the next heat exchange baffle 100 abuts against the outer wall of the protrusion 02 of the previous heat exchange baffle 100. Through the above design, the inner heat exchange baffle 100 can be subjected to a pressing force perpendicular to the first direction, that is, the inner plate 102 can be subjected to an inward compressive force from its edge, which can better resist the internal stress of the heat exchange baffle 100, and thus better maintain the stability of the internal structure of the heat exchanger.

[0033] In some implementations, such as Figure 4 , Figure 5As shown, the side of the heat exchange baffle 100 is recessed to form a bottom 1001 and a side portion 1002 surrounding the outer edge of the bottom 1001. The side portions 1002 and bottom 1001 of each heat exchange baffle 100 are stacked sequentially to form a multi-layered nested structure, with the side portions 1002 inclined outwards relative to the bottom 1001. This inclined arrangement of the side portions 1002 allows the chamber 01 of the heat exchange baffle 100 to gradually increase in size from the inside out, while the corresponding protrusions 02 of the heat exchange baffle 100 gradually narrow along the protruding direction. This facilitates alignment of the heat exchange baffles 100 during the nesting process. Furthermore, it allows the outer heat exchange baffle 100 to exert a compressive force from the side portion 1002 towards the interior of the chamber 01 on the inner heat exchange baffle 100, better counteracting the internal stress of the heat exchange baffle 100 and thus better maintaining the stability of the internal structure of the heat exchanger.

[0034] In some implementations, such as Figure 4 , Figure 5 As shown, multiple heat exchange baffles 100 are arranged along a first direction. Among the multiple heat exchange baffles 100, the two outermost heat exchange baffles 100 are defined as outer baffles 101, and the heat exchange baffle 100 between the two outer baffles 101 is defined as inner baffle 102. A clamping space 03 is formed between the two outer baffles 101 for clamping the inner baffle 102. When the inner baffle 102 is clamped in the clamping space 03, the inner baffle 102 undergoes elastic deformation toward the interior of the clamping space 03. For ease of understanding, in other words, after the outer baffles 101 are assembled to form the clamping space 03, the size of the clamping space 03 is smaller than the size of the inner baffle 102 in its natural state. In actual assembly and production, pressure needs to be applied to the outer baffles 101 to press the inner baffle 102, causing the inner baffle 102 to deform inward, making the external size of the inner baffle 102 smaller, and thus being clamped inside the clamping space 03. The deformation direction of the inner plate 102 includes the direction from the side 1002 of the outer plate 101 toward the interior of the clamping space 03 and the direction from the bottom 1001 of the outer plate 101 toward the interior of the clamping space 03.

[0035] In some embodiments, the thickness of the two outermost heat exchange baffles 100 is greater than the thickness of the inner heat exchange baffles 100, in order to further improve the rigidity of the outer heat exchange baffles 100.

[0036] In some embodiments, a welding portion is further provided at the center of the side surface of the heat exchange baffle 100, which is used for welding and fixing to the welding portion of an adjacent heat exchange baffle 100. For details, please refer to [link / reference needed]. Figure 2 , Figure 4To understand, the aforementioned welded portion is located in the middle of the bottom 1001 of the heat exchange baffle 100. It is understood that, due to the large width of the heat exchange baffle 100, this design allows for the formation of a fixing point in the middle of the bottom 1001 of two adjacent heat exchange baffles 100. This resists relative movement between the heat exchange baffles 100 due to internal stress, thus maintaining the stability of the internal structure of the heat exchanger.

[0037] In some implementations, such as Figure 2 , Figure 3 As shown, the heat exchange baffle 100 has corrugated structures 04 stamped on both sides. The corrugated structures 04 include alternating crests 041 and troughs 042. The crests 041 of adjacent heat exchange baffles 100 abut against each other, and the troughs 042 of the corrugated structures 04 are used to form water flow channels 001 or medium channels 002. It should be noted that the heat exchange baffle 100 is a plate-shaped structure, and the corrugated structures 04 are formed on both sides of the heat exchange baffle 100. The crest 041 on one side of the heat exchange baffle 100 corresponds to the trough 042 on the other side.

[0038] With the above design, the crests 041 of the adjacent heat exchange baffles 100 abut against each other, and the troughs 042 face each other, which helps to maintain the shape of the water flow channel 001 and the medium channel 002 inside the heat exchanger.

[0039] In some implementations, such as Figure 2 , Figure 3 As shown, the heat exchange baffle 100 includes components along its line of symmetry ( Figure 2 , Figure 3 The heat exchange baffle 100 (shown as dashed lines in the diagram) has symmetrically distributed left and right sections, each with a corrugated structure 04. The crests 041 of the left and right sections are inclined relative to the line of symmetry of the heat exchange baffle 100 and are symmetrical to each other. Similarly, the troughs 042 of the left and right sections are also inclined relative to the line of symmetry of the heat exchange baffle 100 and are symmetrical to each other. This design ensures that the direction of the internal stress of the heat exchange baffle 100 is symmetrical and more regular relative to the main body of the heat exchange baffle 100, allowing the outer heat exchange baffle 100 to more effectively constrain the inner heat exchange baffle 100.

[0040] The water treatment equipment provided in this application includes the above-mentioned heat exchange device, which provides a more stable and longer-lasting heat exchange effect.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
