Abstract
Description
Technical Field

[0002] A heat exchanger is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction.
[0003] Heat exchange tubes are an important component of heat exchangers. Due to prolonged heat exchange operations, residues accumulate on the outer surface of the heat exchange tubes, which in turn affects heat exchange efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a technical solution for a high-efficiency heat exchanger that addresses the shortcomings of existing technologies. It can not only continuously clean the heat exchange tubes and reduce the accumulation of residues on the surface of the heat exchange tubes, but also achieve automated cleaning, making it flexible and convenient to use, greatly extending the service life of the heat exchanger. At the same time, it can be cleaned while the heat exchanger is working normally.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A high-efficiency heat exchanger, including
[0007] A housing with an inlet pipe for hot fluid to flow in and an outlet pipe for hot fluid to flow out at both ends. A cooling medium inlet pipe and a cooling medium outlet pipe are connected to the outside of the housing.
[0008] And several heat exchange tubes, which are installed inside the shell through a fixing plate;
[0009] Its features are:
[0010] It also includes a cleaning mechanism located inside the shell, which is connected to the fixed plate. The cleaning mechanism cleans the heat exchange tubes and improves the heat exchange efficiency.
[0011] The above-described structure not only allows for continuous cleaning of the heat exchange tubes, reducing the accumulation of residues on their surface, but also enables automated cleaning, making it flexible and convenient to use and greatly extending the service life of the heat exchanger. Furthermore, it allows for cleaning even when the heat exchanger is operating normally.
[0012] Furthermore, the cleaning mechanism includes a cleaning component, a motor, a screw, and a guide rod. The screw and guide rod are distributed parallel to each other between two fixed plates. The screw is connected to the motor, which is located on one side of the fixed plate. The cleaning component is connected to the screw and the guide rod. By rotating the motor forward or backward, the screw can be driven to rotate forward or backward, causing the cleaning component to move back and forth along the heat exchange tube, thereby achieving continuous cleaning of the surface of the heat exchange tube. The guide rod improves the stability and reliability of the cleaning component during movement.
[0013] Furthermore, the cleaning assembly includes a ring-shaped cleaning ring and a connecting plate for connecting two adjacent cleaning rings. The cleaning ring matches the outer wall of the heat exchange tube and is located in the same vertical plane, ensuring that each heat exchange tube can be cleaned synchronously, improving cleaning efficiency, and without affecting the normal operation of the heat exchanger.
[0014] Furthermore, both the screw and the guide rod horizontally penetrate the connecting plate. Through the design of the screw and the guide rod, the connecting plate can be moved in the horizontal direction, thereby ensuring that each cleaning ring moves synchronously.
[0015] Furthermore, the cleaning rings and heat exchange tubes are arranged in a ring shape or a regular polygon shape, which not only helps to improve heat exchange efficiency, but also does not affect the cleaning of residues on the surface of each heat exchange tube.
[0016] Furthermore, the fixing plate is provided with positioning holes and through holes. The positioning holes are set one-to-one with the heat exchange tubes, and the through holes are used to connect the guide rod and the screw. The positioning holes improve the stability and reliability of the heat exchange tube installation. The through holes connected to the guide rods can be smooth straight holes, and the through holes connected to the screws can be threaded holes, which facilitates the threaded connection between the through holes and the screws.
[0017] Furthermore, the two ends of the shell are respectively provided with a liquid inlet and a liquid outlet. The liquid inlet pipe is connected to the shell through the liquid inlet, and the liquid outlet pipe is connected to the shell through the liquid outlet.
[0018] Furthermore, both the inlet and outlet ports are equipped with conical covers, which not only facilitate the dispersion of the input heat fluid to each heat exchange tube for heat exchange treatment, but also allow the heat fluid after heat exchange to be collected for unified output.
[0019] Furthermore, a connector is provided at the end of the liquid inlet interface.
[0020] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:
[0021] 1. This utility model can not only continuously clean the heat exchange tubes and reduce the accumulation of residues on the surface of the heat exchange tubes, but also realize automated cleaning, which is flexible and convenient to use, greatly extending the service life of the heat exchanger. At the same time, it can be cleaned while the heat exchanger is working normally.
[0022] 2. The forward and reverse rotation of the motor can drive the screw to rotate forward or reverse, causing the cleaning component to move back and forth along the heat exchange tube, thereby achieving continuous cleaning of the surface of the heat exchange tube. The guide rod improves the stability and reliability of the cleaning component during movement. Attached image description:

Detailed Implementation
[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0032] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.
[0033] like Figures 1 to 5 As shown, this utility model discloses a high-efficiency heat exchanger, comprising a shell 1 and a plurality of heat exchange tubes 7. The shell 1 has an inlet pipe 2 for hot fluid to flow in and an outlet pipe 3 for hot fluid to flow out at both ends. A cooling medium inlet pipe 4 and a cooling medium outlet pipe 5 are connected to the outer side of the shell 1. This application uses three heat exchange tubes 7 as an example for illustration.
[0034] The housing 1 has an inlet port 8 and an outlet port 9 at its two ends respectively. The inlet pipe 2 is connected to the housing 1 through the inlet port 8, and the outlet pipe 3 is connected to the housing 1 through the outlet port 9.
[0035] Both the liquid inlet 8 and the liquid outlet 9 are equipped with conical cover structures, which not only facilitate the dispersion of the input hot fluid to each heat exchange tube 7 for heat exchange treatment, but also allow the heat exchanged fluid to be gathered together for unified output.
[0036] The end of the liquid inlet port 8 is provided with a connector 10.
[0037] The heat exchange tube 7 is installed inside the shell 1 via the fixing plate 6.
[0038] The heat exchanger also includes a cleaning mechanism located inside the housing 1. The cleaning mechanism is connected to the fixed plate 6 and cleans the heat exchange tubes 7 to improve heat exchange efficiency.
[0039] The cleaning mechanism includes a cleaning component, a motor 17, a screw 16, and a guide rod 13. The screw 16 and the guide rod 13 are distributed parallel to each other between two fixed plates 6. The screw 16 is connected to the motor 17, which is located on one side of the fixed plate 6. The cleaning component is connected to the screw 16 and the guide rod 13. The forward and reverse rotation of the motor 17 can drive the screw 16 to rotate forward or reverse, causing the cleaning component to move back and forth along the heat exchange tube 7, thereby continuously cleaning the surface of the heat exchange tube 7. The guide rod 13 improves the stability and reliability of the cleaning component during movement.
[0040] The cleaning assembly includes a ring-shaped cleaning ring 14 and a connecting plate 15 for connecting two adjacent cleaning rings 14. The cleaning ring 14 matches the outer wall of the heat exchange tube 7 and is located in the same vertical plane, ensuring that each heat exchange tube 7 can be cleaned synchronously, improving cleaning efficiency, and without affecting the normal operation of the heat exchanger.
[0041] Both the screw 16 and the guide rod 13 pass horizontally through the connecting plate 15. Through the design of the screw 16 and the guide rod 13, the connecting plate 15 can be moved horizontally, thereby ensuring that each cleaning ring 14 moves synchronously.
[0042] The cleaning ring 14 and the heat exchange tube 7 are both arranged in a ring shape or a regular polygon shape, which not only helps to improve the heat exchange efficiency, but also does not affect the cleaning of the residues on the surface of each heat exchange tube 7.
[0043] The fixing plate 6 is provided with positioning holes 12 and through holes 11. The positioning holes 12 are set one-to-one with the heat exchange tubes 7. The through holes 11 are used to connect the guide rod 13 and the screw 16. The positioning holes 12 improve the stability and reliability of the heat exchange tubes 7 installation. The through holes 11 connected to the guide rod 13 can be smooth straight holes, and the through holes 11 connected to the screw 16 can be threaded holes, which facilitates the threaded connection between them.
[0044] The above-described structure not only allows for continuous cleaning of the heat exchange tube 7, reducing the accumulation of residues on its surface, but also enables automated cleaning, making it flexible and convenient to use and greatly extending the service life of the heat exchanger. Furthermore, it allows for cleaning even when the heat exchanger is operating normally.
[0045] In practical use, the hot fluid is introduced into the heat exchange tube 7 through the liquid inlet pipe 2, while the cooling medium is introduced into the shell 1 through the cooling medium inlet pipe 4. After heat exchange, the hot fluid is output through the liquid outlet pipe 3, and the cooling medium flows out through the liquid outlet pipe 3. At the same time, the cleaning mechanism is activated to continuously clean the heat exchange tube 7 to ensure the working efficiency of the heat exchanger.
[0046] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to achieve essentially the same technical effect are all covered within the protection scope of this utility model.
