Description

Technical Field

[0001] This utility model relates to the field of heat exchange structure technology, and in particular to a multi-layer hollow cylindrical evaporator heat exchange structure. Background Technology

[0002] In the field of MVR (Mechanical Vapor Recompression) evaporator technology, the heat exchanger, as a key component, directly affects the efficiency and stability of the entire evaporation system. With the increasing demands for evaporation efficiency and energy conservation in industry, how to increase the heat exchange area and improve heat exchange efficiency has become a critical issue that urgently needs to be addressed in the MVR evaporator technology field. Traditional MVR evaporator heat exchanger designs are often limited by structural form and spatial layout, resulting in a relatively small heat exchange area, making it difficult to achieve efficient heat transfer within a limited space. This limitation not only restricts the evaporator's processing capacity but may also lead to low energy utilization efficiency and increased operating costs. Especially when processing high-concentration, high-viscosity, or easily crystallizing materials, heat exchangers with small heat exchange areas are more prone to clogging and scaling, further affecting the normal operation and service life of the evaporator. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-layer hollow cylindrical evaporator heat exchange structure. By setting an outer layer, a middle layer, and an inner layer, and connecting them with several connecting pipes (pipe 1, pipe 2, and pipe 3), a multi-layer, three-dimensional heat exchanger structure is constructed, which significantly increases the heat exchange area and thus improves the heat exchange efficiency. The increased heat exchange area allows the heat exchanger to transfer more heat in the same amount of time, increasing the heat exchange capacity, accelerating the evaporation process, improving processing capacity, and reducing energy consumption, thereby achieving energy conservation and emission reduction. At the same time, the multi-layer structure design allows the refrigerant to be distributed and flow more evenly within the heat exchanger, reducing system instability. The increased heat exchange area also reduces material blockage and scaling, extends the service life of the heat exchanger, and enhances system stability and reliability.

[0004] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0006] An outer layer structure, inside which a middle layer structure and an inner layer structure coaxial with the outer layer structure are sequentially arranged, and the outer layer structure and the middle layer structure and the inner layer structure are interconnected through a connecting structure.

[0007] The above-mentioned multi-layer hollow cylindrical evaporator heat exchange structure includes an outer layer structure comprising two outer layer plates and two outer layer sealing plates. The ends of the two outer layer plates are sealed and connected by the outer layer sealing plates to form a hollow shell.

[0008] In the above-mentioned multi-layer hollow cylindrical evaporator heat exchange structure, the outer sealing plate at the top has a number of equally spaced outer connecting holes.

[0009] In the aforementioned multi-layer hollow cylindrical evaporator heat exchange structure, an inlet pipe and a drain pipe are sequentially installed on the outer connecting hole located at the bottom.

[0016] This utility model has at least the following beneficial effects:

[0017] 1. This utility model realizes a multi-layer hollow cylindrical evaporator heat exchange structure. By setting an outer layer structure, a middle layer structure, and an inner layer structure, and using several connecting pipes one, two, and three to connect the three layers, a multi-layer, three-dimensional heat exchanger structure is constructed, which significantly increases the heat exchange area and thus improves the heat exchange efficiency. The increased heat exchange area allows the heat exchanger to transfer more heat in the same amount of time, increasing the heat exchange capacity, accelerating the evaporation process, improving processing capacity, and reducing energy consumption, thereby achieving energy saving and emission reduction. At the same time, the multi-layer structure design allows the refrigerant to be distributed and flow more evenly in the heat exchanger, reducing system instability problems. The increased heat exchange area can also reduce material blockage and scaling, extend the service life of the heat exchanger, and enhance the stability and reliability of the system.

[0018] 2. Significantly Increased Heat Exchange Area: This invention features an outer, middle, and inner structure, interconnected by several connecting pipes (pipe 1, pipe 2, and pipe 3), forming a multi-layered, three-dimensional heat exchanger structure. This design greatly increases the refrigerant's surface area without altering the overall size of the evaporator, thereby significantly increasing the heat exchange area and improving heat exchange efficiency.

[0019] 3. Increased heat exchange capacity: Due to the increased heat exchange area, the heat exchanger of this invention can transfer more heat in the same amount of time, thereby increasing the heat exchange capacity. This not only helps to accelerate the evaporation process and improve the evaporator's processing capacity, but also reduces energy consumption to a certain extent, achieving the goal of energy conservation and emission reduction.

[0020] 4. Enhanced System Stability and Reliability: The multi-layered heat exchanger design allows for more uniform distribution and flow of refrigerant within the heat exchanger, reducing system instability caused by localized overheating or undercooling. Simultaneously, the increased heat exchange area helps reduce clogging and scaling on the heat exchanger surface, extending its service life and improving the overall reliability and stability of the system.

[0040] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0041] Please refer to Figures 1 to 8As shown, an embodiment of this utility model provides a multi-layer hollow cylindrical evaporator heat exchange structure, including: an outer layer structure 1, a middle layer structure 2 and an inner layer structure 3 coaxial with the outer layer structure 1 are sequentially arranged inside the outer layer structure 1, and the outer layer structure 1 and the middle layer structure 2 and the middle layer structure 2 and the inner layer structure 3 are interconnected by a connecting structure 4.

[0042] By adopting the above technical solution, and by setting an outer structure 1, a middle structure 2, and an inner structure 3, and connecting the three with several connecting pipes 401-4011-402, a multi-layer, three-dimensional heat exchanger structure is constructed, which significantly increases the heat exchange area and thus improves the heat exchange efficiency. The increased heat exchange area allows the heat exchanger to transfer more heat in the same amount of time, increasing the heat exchange capacity, accelerating the evaporation process, improving processing capacity, and reducing energy consumption, thereby achieving energy conservation and emission reduction. At the same time, the multi-layer structure design allows the refrigerant to be distributed and flow more evenly in the heat exchanger, reducing system instability. The increased heat exchange area can also reduce material blockage and scaling, extend the service life of the heat exchanger, and enhance system stability and reliability.

[0043] In order to construct the outer hollow shell, in this embodiment: the outer structure 1 includes two outer plates 101 and two outer sealing plates 1011. The ends of the two outer plates 101 are sealed and connected by the outer sealing plates 1011 to form a hollow shell. By forming the outer hollow shell, a basic space is provided for the flow and heat exchange of fluids such as refrigerant, ensuring the integrity of the heat exchanger outer structure 1, which is the basis for constructing the entire multi-layer heat exchanger structure.

[0044] In order to achieve communication between the outer layer and the internal structure, in this embodiment, a plurality of outer layer communication holes 102 are provided on the outer layer sealing plate 1011 located at the top. The outer layer communication holes 102 provide an interface for the subsequent connection of the connecting pipe and the outer layer structure 1, so that refrigerant and the like can smoothly enter the internal structure from the outer layer structure 1. This is a key step in realizing fluid exchange between the multi-layer structure.

[0045] In order to enable fluid to enter and exit the outer structure 1, in this embodiment: a water inlet pipe 103 and a drain pipe 1031 are sequentially installed on the outer connecting hole 102 located at the bottom.

[0046] In order to construct the middle hollow shell, in this embodiment: the middle structure 2 includes two middle plate 201 and two middle sealing plate 2011, and the two ends of the two middle plate 201 are sealed and connected through the middle plate 201 to form a hollow shell. The construction of the middle hollow shell further enriches the hierarchical structure of the heat exchanger, provides more flow paths and heat exchange space for fluids such as refrigerant, and helps to improve heat exchange efficiency.

[0047] In order to achieve communication and coordination between the middle layer and the outer and inner layers, in this embodiment, both middle layer sealing plates 2011 are provided with middle layer communication holes 202 that cooperate with the outer layer communication holes 102. The middle layer communication holes 202 cooperate with the outer layer communication holes 102 to allow refrigerant and other fluids to flow smoothly between the outer and middle layer structures 2, ensuring the continuity of fluid exchange between the multi-layer structures, which is the key to building an efficient heat exchange channel.

[0048] In order to construct the inner hollow shell, in this embodiment: the inner structure 3 includes two inner plate 301 and two inner sealing plates 3011, and the two ends of the two inner plate 301 are sealed and connected by the inner sealing plates 3011 to form a hollow shell. The construction of the inner hollow shell improves the multi-layer structure of the heat exchanger, provides the final heat exchange space for fluids such as refrigerant, and makes the entire heat exchanger structure more complete and efficient.

[0049] In order to achieve communication and coordination between the inner layer and the middle layer, in this embodiment, both inner layer sealing plates 3011 are provided with inner layer communication holes 302 that cooperate with the middle layer communication holes 202. The inner layer communication holes 302 and the middle layer communication holes 202 cooperate to allow refrigerant and other fluids to flow smoothly between the middle layer and the inner layer structure 3, further ensuring the continuity of fluid exchange between the multi-layer structure and helping to improve heat exchange efficiency.

[0050] To achieve communication between the outer layer and the middle layer, and between the middle layer and the inner layer, in this embodiment: the communication structure 4 includes a first connecting pipe 401 and a second connecting pipe 4011. The outer layer communication hole 102 is connected to the middle layer communication hole 202 on the middle layer sealing plate 2011 at the bottom of the middle layer plate 201 through the first connecting pipe 401. The middle layer communication hole 202 on the middle layer sealing plate 2011 at the top of the middle layer plate 201 is connected to the inner layer communication hole 302 on the inner layer sealing plate 3011 at the bottom of the inner layer plate 301 through the second connecting pipe 4011. The communication between the outer layer, middle layer and inner layer structure 3 is achieved through the first connecting pipe 401 and the second connecting pipe 4011, thus constructing a complete fluid flow channel. This allows fluids such as refrigerant to flow in an orderly manner between the multi-layer structure, greatly improving the heat exchange efficiency.

[0051] To achieve direct communication between the outer and inner layers, in this embodiment, the communication structure 4 further includes a connecting pipe 402, and the outer layer communication hole 102 is connected to the inner layer communication hole 302 on the inner layer sealing plate 3011 at the top of the inner layer plate 301 through the connecting pipe 402. The outer and inner layers are directly connected through the connecting pipe 402, which increases the path and mode of fluid flow, further optimizes the fluid distribution in the heat exchanger, and helps to improve the heat exchange area and heat exchange efficiency.

[0052] The working principle of this invention is as follows: By cleverly arranging an outer layer structure 1, a middle layer structure 2, and an inner layer structure 3, and utilizing several connecting pipes 401 between the outer layer structure 1 and the middle layer structure 2, several connecting pipes 4011 between the middle layer structure 2 and the inner layer structure 3, and several connecting pipes 402 between the outer layer structure 1 and the inner layer structure 3, the various layers are tightly and orderly connected. This design, without changing the size of the heat exchanger, cleverly alters the refrigerant carrier structure, allowing the refrigerant to flow and exchange heat fully between the multiple layers, greatly increasing the heat exchange area, thereby significantly improving the heat exchange capacity and effectively enhancing the overall performance of the heat exchanger.

However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments.
