Description

Technical Field

[0001] This utility model provides a heat exchange structure, and particularly relates to a high-efficiency heat exchange structure for a plate heat exchanger. Background Technology

[0002] Plate heat exchangers, as a highly efficient heat exchange device, are widely used in chemical, energy, and refrigeration industries. Their core function is to achieve efficient energy exchange and utilization through the transfer of heat between hot and cold media between the plates and tubes. The basic structure of existing plate heat exchangers mostly consists of plates and tubes. The plates are often integral or simply spliced, while the tubes are assembled using direct laying or simple fixing methods.

[0003] However, there are obvious shortcomings in practical applications: On the one hand, the connection between the plates lacks precise positioning and effective separation structure, and the medium flow channel is prone to problems such as poor flow and leakage due to plate misalignment and uneven fitting. Moreover, the overall structural stability is poor, and it is easily deformed by external forces or thermal expansion and contraction, which interferes with heat exchange efficiency. On the other hand, the installation of the tubes relies on conventional fixing methods, which are not well adapted to the plates and are prone to loosening and displacement, reducing the heat exchange contact effect. At the same time, there is a lack of optimized design for the hot and cold circulation system, making it difficult to form an efficient and stable hot and cold medium circulation, which restricts the improvement of heat exchange efficiency and cannot meet the demand for efficient heat exchange in industrial production. Therefore, it is urgent to improve and innovate the structure of plate heat exchangers to break through the existing technical bottlenecks. Utility Model Content

[0004] In order to solve the above problems, this application provides a high-efficiency heat exchange structure for a plate heat exchanger, which solves problems such as unstable plate connection, poor medium flow, loose tube installation, and inefficient heat exchange cycle.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency heat exchange structure for a plate heat exchanger, comprising a plate body and a tube body, wherein the plate body is composed of multiple plates, and the plates are separated and connected by a connecting structure; the tube body is composed of multiple tubes, which are embedded in the plate body and are adapted to fit the plate body.

[0006] Preferably, the connecting structure is used to position and separate adjacent plates, so that a channel for the flow of medium is formed between the plates.

[0007] Preferably, the tube body is fixed to the pre-set mounting groove of the plate body by an embedded structure, and the embedded structure is compatible with the tube body and the plate body to ensure stable installation of the tube body;

[0008] Preferably, the connecting structure consists of multiple bolt mounting plates with separators, which are evenly distributed around the perimeter of the plate body. The bolt mounting plates are connected to an external pre-set structure via bolts.

[0011] This device addresses the limitations of existing plate heat exchangers, such as limited heat exchange efficiency, insufficient structural connection stability, and susceptibility to problems in media flow and tube installation. It utilizes a connecting structure to create channels for media flow, optimizing media flow and enhancing heat exchange. An embedded structure mounts the tubes into the plate mounting slots, ensuring tube stability and improving heat exchange contact.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[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 in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] like Figure 1 and Figure 2 As shown, a high-efficiency heat exchange structure for a plate heat exchanger includes a plate body and a tube body. The plate body is composed of multiple plates 1 connected by a connecting structure 3. The tube body includes multiple tubes 2, which are fitted and embedded in the plates 1. The connecting structure 3 is used to position and separate adjacent plates 1, forming a medium flow channel 4. It is a bolt mounting plate 8 with a separator 7, which is evenly distributed around the plate and connected to an external pre-set structure by bolts. The tubes 2 are installed in the mounting grooves 6 of the plates 1 through the embedding structure 5 to ensure stability. One end of the tube 2 is connected to a water storage tank 9 above the plate, which includes cold water and hot water circulation tanks, and the two are connected by an external connecting pipe.

[0023] In this implementation scheme, plate 1 is precisely positioned by bolt mounting plate 8 and separator 7 via connecting structure 3. The bolt structure secures it to the external pre-set structure, forming a uniform and sealed channel 4 between the plates, preventing media leakage and optimizing the flow path. Pipe 2 achieves a tight fit through the fitting of embedded structure 5 and mounting groove 6, enhancing heat transfer efficiency. The cold and hot water circulation tanks of water storage tank 9 form a closed loop via external connecting pipes, achieving heat exchange through pipe 2. The innovation of this structural combination lies in: connecting structure 3 ensuring plate stability while forming an efficient flow channel; embedded structure 5 increasing the tube sheet contact area; and circulation tank design enhancing heat recycling. These three elements work together to solve the problems of structural looseness, turbulent flow, and low heat exchange efficiency in traditional heat exchangers, achieving a heat exchange efficiency increase of over 30%, a 20% reduction in energy consumption, and significantly improved installation and maintenance convenience.

[0024] like Figure 3 andFigure 4 As shown, a high-efficiency heat exchange structure for a plate heat exchanger includes a plate body section consisting of multiple plates 1 connected by a connecting structure 3, and a tube body section consisting of multiple tubes 2 fitted and embedded in the plate body 1 for coordinated operation. The connecting structure 3 serves as a bolt mounting plate 8 with separators 7, distributed around the plate body and connecting to the outside, both positioning and separating the plate bodies 1 to form a medium channel 4, and enabling overall installation. The tubes 2 are securely mounted in the mounting grooves 6 of the plate body 1 by an embedded structure 5, ensuring heat exchange contact. The water storage tank 9 connected to the tubes 2 above the plate body is connected to a cold water and hot water circulation tank via an external pipe to form a circulation system, contributing to efficient heat exchange.

[0025] In this embodiment, in the actual use of this device, it is necessary to use a pump body in the prior art to drive the medium to flow in the circulation system composed of channel 4 and water storage tank 9 to ensure that the hot and cold medium can circulate continuously to achieve efficient heat exchange; at the same time, the temperature of the medium in water storage tank 9 and pipe 2 can be monitored by the temperature sensor in the prior art, so as to facilitate real-time control of the heat exchange process. In terms of material selection, plate 1 can be made of corrosion-resistant and thermally conductive stainless steel, such as 304 stainless steel, to ensure service life under complex working conditions; tube 2 is made of copper, utilizing its excellent thermal conductivity to improve heat transfer efficiency; bolt mounting plate 8 in connection structure 3 is made of high-strength aluminum alloy, which reduces overall weight while ensuring connection strength; separator 7 is made of high-temperature resistant and highly elastic silicone rubber, which can achieve reliable sealing and buffer the force between plates; embedded structure 5 can be made of engineering plastic, such as polytetrafluoroethylene, whose wear-resistant and chemical corrosion-resistant properties help ensure stable installation and long-term use of tube 2, thus forming a complete, reliable and efficient heat exchange system with the assistance of existing technology.

[0026] Specifically, in one or more feasible embodiments, during installation, multiple plates 1 are first positioned to externally pre-set fixing brackets via bolt mounting plates 8 in the connecting structure 3. An electric torque wrench (in the prior art) is used to evenly tighten the bolts, ensuring that the separator 7 fits tightly against adjacent plates 1, forming a stable and sealed medium flow channel 4. During pipe 2 installation, a positioning fixture (in the prior art) is used to precisely place the pipe 2 into the mounting groove 6 of the plate 1. Fixing is completed manually or with the aid of tools such as a pneumatic screwdriver, using the snap-fit ​​or threaded engagement of the embedded structure 5, ensuring tight contact between the pipe 2 and the plate 1.

[0027] In operation, a centrifugal pump, using existing technology, is connected to the inlet and outlet of the water storage tank 9. The pump's flow rate and head parameters are set, and the low-temperature medium from the cold water circulation tank is pumped into the pipe body 2. Simultaneously, the high-temperature medium to be heat-exchanged is introduced through a pipe into the channel 4 between the plates 1, allowing for full heat exchange between the high-temperature medium and the outer wall of the pipe body 2. A temperature sensor is connected to the existing PLC control system to monitor the temperature of the medium in the cold water circulation tank, hot water circulation tank, and channel 4 of the plate body 1 in real time. Based on the set temperature threshold, the speed of the centrifugal pump is automatically adjusted to control the medium flow rate and optimize heat exchange efficiency. When cleaning and maintenance are required, a high-pressure cleaning device, using existing technology, is used to flush the channel 4 and the inside of the pipe body 2 through the pipe interface. After removing the bolts from the bolt mounting plate 8, the plate body 1 can be easily inspected and replaced. The entire process is efficient and convenient, fully utilizing the high-efficiency heat exchange performance of this device.

[0028] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
