Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment, and in particular to a plate heat exchanger with a reinforcement device. Background Technology

[0002] Plate heat exchangers are high-efficiency heat exchange devices composed of a series of metal plates with a specific corrugated shape. They are widely used in industries such as chemical, food, and pharmaceutical due to their high heat transfer efficiency, compact structure, and small footprint. However, in existing plate heat exchangers, the heat exchange plates are only fixed by clamps at both ends. When the internal fluid pressure fluctuates significantly, the plates are prone to deformation. Over time, this can lead to a decrease in the sealing performance between the plates, resulting in leaks and affecting the normal operation and service life of the equipment.

[0003] Therefore, a plate heat exchanger with a reinforcement device is proposed to solve the above problems. Utility Model Content

[0004] This invention overcomes the shortcomings of the prior art and provides a plate heat exchanger with a reinforcement device. By setting a reinforcement device on the outside of the heat exchange core, the overall structural stability is improved and the risk of plate deformation and leakage is reduced.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a plate heat exchanger with a reinforcement device, comprising: a heat exchange core formed by stacking multiple heat exchange plates sequentially, a reinforcement device being provided on the outside of the heat exchange core, the reinforcement device comprising oppositely arranged reinforcement components, each set of reinforcement components comprising a transverse reinforcement member and a longitudinal reinforcement member, the transverse reinforcement member being arranged along the width direction of the heat exchange core and abutting against the edge of the heat exchange plate, the longitudinal reinforcement member being arranged along the height direction of the heat exchange core and having both ends connected to the transverse reinforcement member, the transverse reinforcement member and the longitudinal reinforcement member forming a reinforcement frame to apply radial constraint force to the heat exchange core.

[0006] In a preferred embodiment of this utility model, the longitudinal reinforcement includes an outer rod and an inner rod. The outer rod is a hollow structure, with one end being an open end and the other end being a closed end. The inner rod can be inserted into the outer rod through the open end and fixed by a locking bolt.

[0007] In a preferred embodiment of this utility model, both the closed end of the outer rod and the free end of the inner rod are connected to the transverse reinforcement.

[0008] In a preferred embodiment of the present invention, the reinforcement device further includes an end reinforcement member, which is disposed at the end of the heat exchange core, and the transverse reinforcement member is inserted into the end reinforcement member.

[0009] In a preferred embodiment of the present invention, the end reinforcement is provided with a plurality of weight-reducing holes, which are evenly distributed along the length direction of the end reinforcement.

[0010] In a preferred embodiment of this utility model, the transverse reinforcement and the longitudinal reinforcement are made of high-strength alloy steel and have an anti-corrosion coating on their surfaces.

[0011] In a preferred embodiment of this utility model, the number of the reinforcing components is four sets, and the four sets of reinforcing components are respectively disposed at the four side edges of the heat exchange core.

[0012] In a preferred embodiment of the present invention, the heat exchange plates are provided with concave and convex textures, and the concave and convex textures between the two heat exchange plates are arranged in a 180-degree opposite combination.

[0013] In a preferred embodiment of the present invention, the transverse reinforcement member is provided with an arc-shaped abutment portion on the side near the heat exchange core that is adapted to the edge of the heat exchange plate, and the inner wall of the arc-shaped abutment portion is provided with an elastic buffer layer.

[0014] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0015] (1) Improve structural stability: The reinforcement frame is formed by the horizontal and vertical reinforcement components of the reinforcement device, which applies radial constraint force to the heat exchange core. This can effectively resist the impact of fluid pressure fluctuations on the heat exchange core, reduce the overall shaking or dispersion of the core formed by multiple heat exchange plates due to uneven force, and significantly improve the overall structural stability of the heat exchange core.

[0016] (2) Reduce plate damage and leakage: The arc-shaped contact part of the transverse reinforcement is adapted to the edge of the heat exchange plate, increasing the contact area while reducing local pressure; the inner elastic buffer layer can alleviate the rigid collision between the reinforcement and the plate, and avoid the plate edge from wear or deformation due to long-term stress, thereby reducing the sealing failure and fluid leakage caused by plate deformation.

[0017] (3) Enhanced applicability and flexibility: The longitudinal reinforcement adopts a telescopic structure, and the length can be flexibly adjusted according to the height of the heat exchange core, which is suitable for plate heat exchangers of different specifications and expands the application range of the device; the four sets of reinforcement components can be selected according to actual stability requirements, taking into account both reinforcement effect and ease of use.

[0018] (4) Extend the service life of the equipment: The end reinforcement and the reinforcement frame form a wrapped reinforcement space, which constrains the heat exchange core from multiple directions and further reduces the probability of plate fatigue damage; the reinforcement made of high-strength alloy steel, combined with the anti-corrosion coating, improves the corrosion resistance and structural strength of the reinforcement device itself, reduces the frequency of equipment maintenance, and extends the service life of the overall equipment.

[0019] (5) Optimize equipment performance: The weight reduction holes on the end reinforcement reduce the overall weight of the device while ensuring the reinforcement strength, thus reducing the load during equipment operation; the reinforcement device provides stable constraint on the heat exchange core, making the fluid flow between the heat exchange plates smoother, reducing flow field disturbance caused by plate shaking, and indirectly improving heat exchange efficiency.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] like Figures 1 to 4 As shown, a plate heat exchanger with a reinforcement device 2 includes: a heat exchange core 1 formed by stacking multiple heat exchange plates in sequence; the heat exchange plates are provided with concave and convex textures 10; the concave and convex textures 10 between two heat exchange plates are arranged in a 180-degree opposite combination; the concave and convex ridges between two heat exchange plates form interlaced contact points; the interlaced contact points form an interlaced flow structure; these interlaced flow structures cause strong turbulence of hot and cold fluids in the plate heat exchanger, thereby achieving a high heat exchange effect.

[0030] A reinforcement device 2 is provided on the outside of the heat exchange core 1. The reinforcement device 2 includes four sets of reinforcement components 20 arranged opposite to each other. The four sets of reinforcement components 20 are respectively arranged at the four side edges of the heat exchange core 1. The arrangement of the four sets of reinforcement components 20 can be selected according to the actual stability requirements, taking into account both reinforcement effect and ease of use.

[0031] Each set of reinforcing components 20 includes a transverse reinforcing member 200 and a longitudinal reinforcing member 201. The transverse reinforcing member 200 is arranged along the width direction of the heat exchange core 1 and abuts against the edge of the heat exchange plate. The longitudinal reinforcing member 201 is arranged along the height direction of the heat exchange core 1 and its two ends are respectively connected to the transverse reinforcing member 200. The transverse reinforcing member 200 and the longitudinal reinforcing member 201 form a reinforcing frame to apply radial constraint force to the heat exchange core 1. The reinforcing frame formed by the transverse reinforcing member 200 and the longitudinal reinforcing member 201 of the reinforcing device 2 applies radial constraint force to the heat exchange core 1, which can effectively resist the impact of fluid pressure fluctuations on the heat exchange core 1, reduce the overall shaking or dispersion of the core formed by multiple heat exchange plates due to uneven force, and significantly improve the overall structural stability of the heat exchange core 1.

[0032] In a preferred embodiment of this utility model, the longitudinal reinforcement 201 includes an outer rod 2010 and an inner rod 2011. The outer rod 2010 is a hollow structure with one open end and the other closed end. The inner rod 2011 can be inserted into the outer rod 2010 through the open end and fixed by a locking bolt 2012. Both the closed end of the outer rod 2010 and the free end of the inner rod 2011 are connected to the transverse reinforcement 200. The longitudinal reinforcement 201 adopts a telescopic structure, and its length can be flexibly adjusted according to the height of the heat exchange core 1. It is suitable for plate heat exchangers of different specifications, thus expanding the application range of the device.

[0033] In a preferred embodiment of this invention, the reinforcement device 2 further includes an end reinforcement member 21, which is disposed at the end of the heat exchange core 1. A transverse reinforcement member 200 is inserted into the end reinforcement member 21, and the end reinforcement member 21 and the reinforcement frame form a wrap-around reinforcement space, constraining the heat exchange core 1 from multiple directions and further reducing the probability of plate fatigue damage. The end reinforcement member 21 is provided with multiple weight-reducing holes 210, which are evenly distributed along the length of the end reinforcement member 21. These weight-reducing holes 210 on the end reinforcement member 21 reduce the overall weight of the device while ensuring reinforcement strength, thus reducing the load on the equipment during operation.

[0034] In a preferred embodiment of this utility model, the transverse reinforcement 200 and the longitudinal reinforcement 201 are made of high-strength alloy steel and have an anti-corrosion coating on their surfaces. The high-strength alloy steel reinforcement, combined with the anti-corrosion coating, improves the corrosion resistance and structural strength of the reinforcement device 2, reduces the frequency of equipment maintenance, and extends the service life of the overall equipment.

[0035] In a preferred embodiment of this utility model, the transverse reinforcement 200 is provided with an arc-shaped abutment portion 2001 adapted to the edge of the heat exchange plate on the side near the heat exchange core 1. The inner wall of the arc-shaped abutment portion 2001 is provided with an elastic buffer layer. The arc-shaped abutment portion 2001 of the transverse reinforcement 200 is adapted to the edge of the heat exchange plate, which increases the contact area and reduces the local pressure. The inner elastic buffer layer can alleviate the rigid collision between the reinforcement and the plate, and avoid wear or deformation of the plate edge due to long-term stress, thereby reducing the sealing failure and fluid leakage problems caused by plate deformation.

[0036] In use, the length of the longitudinal reinforcement 201 is adjusted according to the size of the heat exchange core 1. Specifically, the length of the inner rod 2011 inserted into the outer rod 2010 is adjusted, and then fixed by the locking bolt 2012. The reinforcement component 20 and the end reinforcement 21 are installed in place, so that the arc-shaped abutment part 2001 of the transverse reinforcement 200 is tightly abutted against the edge of the heat exchange plate, forming a comprehensive reinforcement of the heat exchange core 1. During equipment operation, the transverse reinforcement 200 and the longitudinal reinforcement 201 of the reinforcement device 2 form a reinforcement frame, applying radial constraint force to the heat exchange core 1. This effectively resists the impact of fluid pressure fluctuations on the heat exchange core 1, reduces the overall shaking or dispersion of the core formed by multiple heat exchange plates due to uneven force, significantly improves the overall structural stability of the heat exchange core 1, effectively resists the impact of fluid pressure fluctuations on the heat exchange core 1, and reduces the risk of plate deformation and leakage.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
