Description

Technical Field

[0001] This utility model relates to the field of shell-and-tube condenser technology, and in particular to a high-efficiency and energy-saving heat exchange shell-and-tube condenser. Background Technology

[0002] Shell-and-tube condensers, as highly efficient heat exchange devices, are widely used in refrigeration and air conditioning, chemical, and food processing industries. Their core principle is to achieve heat exchange between two fluids through heat exchange tubes inside the shell and tubes. Typically, the cooling medium flows inside the heat exchange tubes, while the medium to be condensed flows in the gap between the shell and the heat exchange tubes, completing the heat transfer through conduction via the tube walls.

[0003] Traditional heat exchange tubes are mostly hollow straight tubes. When the cooling medium flows inside the tube, a thick thermal boundary layer is easily formed on the tube wall, which hinders heat transfer. The temperature difference between the medium in the central region of the tube and the medium near the tube wall is large (in a laminar flow state), resulting in insufficient heat exchange and affecting heat exchange efficiency.

[0004] Therefore, we propose a high-efficiency and energy-saving shell-and-tube condenser. Utility Model Content

[0005] In view of this, the present invention provides a high-efficiency and energy-saving shell-and-tube condenser to solve the problem of low heat exchange efficiency in existing shell-and-tube condensers.

[0006] A high-efficiency and energy-saving shell-and-tube condenser includes a shell tube. End plate holes are provided on the end plates at both ends of the shell tube. A straight heat exchange tube is connected between the opposite end plate holes at both ends of the shell tube. A baffle rod is installed at the center of the end plate holes at both ends of the shell tube. The baffle rod passes through the inside of the heat exchange tube, and a fluid channel is formed between the baffle rod and the inner wall of the heat exchange tube.

[0007] Preferably, the aforementioned spoiler is a stainless steel rod, and the surface of the spoiler is provided with irregular spiral spoiler plates or hemispherical spoiler blocks.

[0008] Preferably, the aforementioned spoiler is a wire rope made of multiple stainless steel wires twisted together.

[0009] Preferably, one end of the aforementioned spoiler is fixedly connected to a hollow-structured fixed bucket, and the other end of the spoiler is threadedly fitted with a hollow-structured locking bucket.

[0010] Preferably, the fixed bucket mentioned above includes a first pressure ring that can press against the periphery of the end plate hole. A first inner ring is fixedly connected to one side of the first pressure ring via a first connecting strip. The first inner ring can be inserted into the end plate hole. A connecting post is fixedly connected to one side of the first inner ring via a second connecting strip. The connecting post is fixedly connected to one end of the turbulence rod.

[0011] Preferably, multiple first connecting strips and second connecting strips are provided and are evenly arranged on both ends of the first inner ring. Both the first connecting strips and the second connecting strips are made of stainless steel.

[0012] Preferably, the end of the aforementioned spoiler rod away from the fixed bucket is provided with a connecting part, the connecting part is provided with a threaded part, the locking bucket includes a threaded cylinder that can be threadedly installed on the threaded part, one side of the threaded cylinder is connected to a second inner ring through a third connecting strip, the second inner ring can be inserted into the end plate hole, and one side of the second inner ring is connected to a second pressure ring through a fourth connecting strip.

[0013] Preferably, multiple third and fourth connecting strips are provided and are evenly arranged on both ends of the second inner ring. Both the third and fourth connecting strips are made of stainless steel.

[0014] Preferably, a handle is fixedly connected to one end face of the second pressure ring.

[0015] Implementing the embodiments of this utility model will have the following beneficial effects: After adopting the above-mentioned high-efficiency and energy-saving shell-and-tube condenser; By inserting a baffle rod inside the straight heat exchange tube, the cooling medium can only flow along the narrow gap between the baffle rod and the inner wall of the heat exchange tube, which greatly increases the medium flow rate. The irregular spiral baffles or hemispherical baffles on the surface of the baffle rod, or the baffle rod being made of steel wire rope (the steel wire rope has its own spiral pattern), can actively break the thermal boundary layer, promote intense mixing of the medium, increase the heat exchange area and heat transfer coefficient, and improve the heat exchange efficiency. At the same time, it can break the laminar flow state of the medium in the heat exchange tube, forcing the medium to form turbulent flow in the tube, making full use of the fluid's cooling capacity, and thus saving more energy; Furthermore, this application employs a hollowed-out fixed bucket and a hollowed-out locking bucket, making the installation and locking of the deflector bar convenient and quick, and easy to disassemble.

[0019] 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 application pertains; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application, are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Example 1

[0022] Please see Figure 1-5As shown, a high-efficiency and energy-saving shell-and-tube condenser includes a shell tube 100. End plate holes 201 are formed on end plates 200 at both ends of the shell tube 100. Straight heat exchange tubes are connected between the opposite end plate holes 201 at both ends of the shell tube 100. A flow-tightening rod 300 is installed at the center of the end plate holes 201 at both ends of the shell tube 100. The flow-tightening rod 300 passes through the interior of the heat exchange tube, and a fluid channel is formed between the flow-tightening rod 300 and the inner wall of the heat exchange tube. It should be noted that... Figure 1 and Figure 2 Only one baffle rod 300 is shown in the drawing, but in practice, there is a baffle rod 300 in each end plate hole 201, one by one.

[0023] Through the above design, the baffle rods 300 are spaced inside the heat exchange tube, forcing the fluid to flow along the gap (which is thinner) between the baffle rods 300 and the inside of the heat exchange tube, thereby increasing the heat exchange efficiency. At the same time, the baffle characteristics are used to avoid uneven heat exchange.

[0024] In practice, the spoiler 300 is made of stainless steel, and its surface is provided with irregularly spiraled spoiler vanes 302 (e.g., Figure 3 As shown in the diagram, it should be further noted that the baffle 302 has an intermittent structure, and the pitch must be greater than the inner diameter of the heat exchange tube. A gap of 2-5 mm is maintained between the baffle 302 and the inner wall of the heat exchange tube. The baffle 302 mainly serves to deflect and turbulent the flow.

[0025] Alternatively, the surface of the spoiler bar 300 may be provided with hemispherical spoiler blocks (not shown in the figure). The spoiler blocks are mainly used for turbulence.

[0026] In implementation, such as Figure 3 Therefore, one end of the baffle rod 300 is fixedly connected to a hollow-structured fixed bucket 301, and the other end of the baffle rod 300 is threadedly fitted with a hollow-structured locking bucket 400. The fixed bucket 301 is hollow, not completely obstructing the fluid, and in conjunction with the baffle rod 300, it allows the fluid to be introduced into the interior of the heat exchange tube and between the baffle rod 300, thus facilitating sufficient heat exchange.

[0027] In implementation, the fixed bucket 301 includes a first pressure ring 305 that can press against the periphery of the end plate hole 201. One side of the first pressure ring 305 is fixedly connected to a first inner ring 307 via a first connecting strip 306. The first inner ring 307 can be inserted into the end plate hole 201. One side of the first inner ring 307 is fixedly connected to a connecting post 309 via a second connecting strip 308. The connecting post 309 is fixedly connected to one end of the turbulence rod 300.

[0028] The first connecting strip 306 and the second connecting strip 308 are provided in multiple quantities (e.g., 4, 6, or 8 strips), and are evenly arranged on both ends of the first inner ring 307. Both the first connecting strip 306 and the second connecting strip 308 are made of stainless steel. Multiple first connecting strips 306 form a cylindrical structure.

[0029] In implementation, the end of the spoiler bar 300 away from the fixed bucket 301 is provided with a connecting part 303, and the connecting part 303 is provided with a threaded part 304. The locking bucket 400 includes a threaded cylinder 401 that can be threaded onto the threaded part 304. One side of the threaded cylinder 401 is connected to a second inner ring 403 through a third connecting strip 402. The second inner ring 403 can be inserted into the end plate hole 201. One side of the second inner ring 403 is connected to a second pressure ring 405 through a fourth connecting strip 404. In specific installation, an elastic rubber ring can also be fitted between the second pressure ring 405 and the end plate 200 to provide cushioning and protection.

[0030] The third connecting strip 402 and the fourth connecting strip 404 are provided in multiple quantities (e.g., 4, 6, or 8 strips), and are evenly arranged on both ends of the second inner ring 403. Both the third connecting strip 402 and the fourth connecting strip 404 are made of stainless steel. Multiple fourth connecting strips 404 form a cylindrical structure.

[0031] Additionally, a handle 406 is fixedly connected to one end face of the second pressure ring 405. It should be noted that the handle 406 does not necessarily have to be rotated manually. Since the handle 406 itself is small, an auxiliary sleeve tool can be used to put on the handle 406 and then rotated so that the threaded cylinder 401 is threaded onto the threaded part 304. Example 2

[0032] Unlike Embodiment 1, the deflector 300 is a steel wire rope made of multiple twisted stainless steel wires. The surface of the steel wire rope has a spiral-like texture, which can conveniently deflect and guide the flow.

[0033] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this application's specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the scope of patent protection of this application.
