Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a low-resistance heat exchanger turbulence deflector assembly. Background Technology

[0002] A heat exchanger is a crucial heat transfer device whose core function is to achieve efficient heat exchange between two or more fluids (liquids or gases) at different temperatures. In most designs, the hot and cold fluids are physically separated by solid walls (such as metal tubes or plates) to prevent direct mixing, and heat is conducted from the high-temperature fluid to the low-temperature fluid through the walls. Its applications are extremely wide-ranging, making it an indispensable basic device in many industrial sectors, including energy, petrochemicals, power generation, HVAC, refrigeration, food processing, and metallurgy. Whether used to heat process fluids, cool equipment (such as engines or electronic components), condense steam, evaporate liquids, or recover waste heat to improve energy efficiency, heat exchangers play a key role. Their performance directly affects the system's energy consumption, operating costs, equipment safety, and environmental benefits, making them one of the core components of modern thermal engineering.

[0003] Fluids in smooth channels form a laminar boundary layer that hinders heat transfer. Turbulence fins significantly improve heat transfer efficiency (up to 1.5–4 times that of smooth tubes) by creating turbulence, disrupting the boundary layer, or inducing secondary flow. Conventional designs (such as dense, continuous fins), while enhancing heat transfer, substantially increase fluid resistance (pressure drop). For every doubling of resistance, pump / fan power consumption can increase threefold (since power consumption ∝ pressure drop × flow rate), leading to a sharp drop in system efficiency. Furthermore, dust accumulation in the hot flow zone can occur during operation, and the shape of the fins themselves, combined with the device's inherent difficulty in cleaning, negatively impacts performance. Therefore, we propose a low-resistance heat exchanger fin assembly. Utility Model Content

[0004] The purpose of this invention is to provide a low-resistance heat exchanger baffle assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A low-resistance heat exchanger baffle assembly includes: a first connection port, characterized in that: a baffle assembly is fixedly connected to the back of the first connection port, a cleaning assembly is fixedly connected to the inner wall of the baffle assembly, the size of the cleaning assembly matches the size of the inner wall of the baffle assembly, the size distance of the cleaning assembly matches the inner wall of the baffle assembly, a motor stabilizing plate is fixedly connected to the top of the baffle assembly, and a second connection port is fixedly connected to the back of the baffle assembly.

[0007] Preferably, the spoiler assembly includes a connecting pipe, a protective shell, a drive motor, a rotating central shaft, a transmission gear, a side linkage gear, a connecting shaft, a spoiler body, a rotating base, and a connecting column. The connecting pipe is fixedly connected to the back of the first connecting port, the protective shell is fixedly connected to one side of the connecting pipe, the drive motor is disposed on the top of the protective shell, and the rotating central shaft is fixedly connected to the bottom of the drive motor.

[0008] Preferably, the transmission gear is fixedly connected to the bottom of the rotating central shaft, the side linkage gear is disposed on one side of the bottom of the transmission gear, the connecting shaft is fixedly connected to the back of the side linkage gear, the connecting shaft is disposed on one side of the protective shell, and the spoiler body is fixedly connected to the surface of the connecting shaft.

[0009] Preferably, the rotating base is disposed on the back of the connecting shaft, and a plurality of connecting posts are fixedly connected to the top side of the rotating base, wherein the connecting posts are disposed on the top of the inner wall of the second connecting port.

[0010] Preferably, the dust removal assembly includes a fixed mounting plate, a fixing nail, a side dust removal brush, and a center dust removal brush. The multiple fixed mounting plates are fixedly connected to the inner wall of the connecting pipe, and the fixing nail is fixedly connected between the surface of the fixed mounting plate and the connecting pipe.

[0011] Preferably, a plurality of the side cleaning brushes are fixedly connected to one side of the inner wall of the fixed mounting plate, and a plurality of the center cleaning brushes are fixedly connected to the middle of the inner wall of the fixed mounting plate.

[0012] Preferably, a connecting stabilizing plate is fixedly connected to the back of the motor stabilizing plate, and the bottom of the connecting stabilizing plate is fixedly connected to the top of the turbulence assembly.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The flow-deflecting components utilize their own streamlined internal structure to reduce flow separation and shape drag. They also employ a structure with large gaps to form a discrete layout, allowing the fluid to recover pressure between the flow-deflecting units and avoiding continuous blockage. At the same time, the internal structure keeps the flow-deflecting plate itself active, using large-scale vortices to mix hot and cold fluids, achieving maximum heat transfer gain with minimal resistance. During operation, the cleaning components continuously clean the dust from the flow-deflecting plates to prevent blockage and further improve the flow-deflecting effect of the device.

[0015] 2. The heat exchange efficiency is improved by assisting the structure of the turbulence component. The first connection port is connected by a connecting pipe, and the protective shell provides external protection for the drive motor, rotating shaft, transmission gear, and side linkage gear. The drive motor drives the rotating shaft to rotate, which in turn drives the transmission gear to rotate. The rotation of the transmission gear drives the side linkage gear to rotate, which in turn drives the connecting shaft to rotate. At the same time, the surface of the turbulence plate body rotates continuously. The rotation of the turbulence plate body can mix the hot and cold fluids with large-scale vortices, achieving the maximum heat transfer gain with the least resistance. Furthermore, the turbulence plate body is not installed in a covering manner on the inner wall of the connecting pipe, but leaves gaps. This gap forms a discrete layout, allowing the fluid to restore pressure between the turbulence units and avoiding continuous blockage. The rotating base and connecting column can be installed and stabilized on the other side of the connecting shaft. With the protective shell at the front end of the connecting shaft, the installation on both sides is stabilized, improving the functionality and safety of the turbulence component.

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.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] A low-resistance heat exchanger baffle assembly includes: a first connection port 1, characterized in that: a baffle assembly 2 is fixedly connected to the back of the first connection port 1, a cleaning assembly 3 is fixedly connected to the inner wall of the baffle assembly 2, the size of the cleaning assembly 3 matches the size of the inner wall of the baffle assembly 2, the size distance of the cleaning assembly 3 matches the inner wall of the baffle assembly 2, a motor stabilizing plate 4 is fixedly connected to the top of the baffle assembly 2, a second connection port 6 is fixedly connected to the back of the baffle assembly 2, a connecting stabilizing plate 5 is fixedly connected to the back of the motor stabilizing plate 4, and the bottom of the connecting stabilizing plate 5 is fixedly connected to the top of the baffle assembly 2.

[0027] In this embodiment, the first connection port 1 and the second connection port 6 can help the device be connected to the inside of the heat exchanger. The turbulence component 2 can use its own structure to turbulent the airflow and improve the overall heat transfer effect of the device. At the same time, it works with the dust removal component 3 to clean itself during use and prevent dust accumulation from affecting the use. The motor stabilizing plate 4 can help stabilize the drive motor 203 inside the turbulence component 2 during operation. The connecting stabilizing plate 5 can help fix the motor stabilizing plate 4 to the top part of the connecting pipe 201, thereby providing a fixed base and further improving the safety of the device.

[0028] The turbulence-disrupting assembly 2 includes a connecting pipe 201, a protective shell 202, a drive motor 203, a rotating central shaft 204, a transmission gear 205, a side linkage gear 206, a connecting shaft 207, a turbulence-disrupting plate body 208, a rotating base 209, and a connecting hanging column 210. The connecting pipe 201 is fixedly connected to the back of the first connecting port 1, the protective shell 202 is fixedly connected to one side of the connecting pipe 201, the drive motor 203 is located on the top of the protective shell 202, and the rotating central shaft 204 is fixedly connected to the bottom of the drive motor 203.

[0029] In this embodiment, the turbulence component 2 uses the connecting pipe 201 to provide space for heat exchange. At the same time, the protective shell 202 uses its own structure to protect the internal rotating shaft 204, transmission gear 205, and side linkage gear 206, and to stably place one end of the connecting shaft 207, thereby improving the safety and stability of the turbulence component 2. The rotating shaft 204 can rotate under the action of the drive motor 203, thus providing a basis for the rotation of the turbulence component 2.

[0030] The transmission gear 205 is fixedly connected to the bottom of the rotating central shaft 204, the side linkage gear 206 is set on one side of the bottom of the transmission gear 205, the connecting shaft 207 is fixedly connected to the back of the side linkage gear 206, the connecting shaft 207 is set on one side of the protective shell 202, and the spoiler body 208 is fixedly connected to the surface of the connecting shaft 207.

[0031] In this embodiment, the transmission gear 205 can rotate under the action of the rotating central shaft 204, thereby driving the side linkage gear 206 at the bottom to rotate. This rotation will drive the rotation of the connecting shaft 207, thereby driving the turbulence plate body 208 to rotate. The rotation of the turbulence plate body 208 can mix hot and cold fluids with large-scale vortices, exchanging the maximum heat transfer gain for the minimum resistance. Furthermore, the turbulence plate body 208 is not installed in a covering manner on the inner wall of the connecting pipe 201, but leaves gaps. This gap is used to form a discrete layout, allowing the fluid to restore pressure between the turbulence units and avoiding continuous blockage, thereby improving the overall turbulence effect of the device.

[0032] The rotating base 209 is located on the back of the connecting shaft 207, and multiple connecting posts 210 are fixedly connected to the top side of the rotating base 209. The connecting posts 210 are located on the top of the inner wall of the second connecting port 6.

[0033] In this embodiment, the rotating base 209 can provide a rotational basis for the rotation of the connecting shaft 207 on one side, and at the same time, it works with the connecting hanging column 210 to fix itself to the inner wall of the second connecting port 6, thereby completing the foundation for fixing one end and improving the stability of the turbulence component 2.

[0034] The dust removal assembly 3 includes a fixed mounting plate 301, a fixing nail 302, a side dust removal brush 303, and a center dust removal brush 304. Multiple fixed mounting plates 301 are fixedly connected to the inner wall of the connecting pipe 201, and the fixing nail 302 is fixedly connected between the surface of the fixed mounting plate 301 and the connecting pipe 201.

[0035] In this embodiment, the dust removal component 3 is fixed to the inner wall of the connecting pipe 201 by the fixed mounting plate 301, thereby completing the fixed foundation. The fixing nail 302 can further reinforce the installation and fixing of the fixed mounting plate 301 by its own structure.

[0036] Multiple side cleaning brushes 303 are fixedly connected to one side of the inner wall of the fixed mounting plate 301, and multiple center cleaning brushes 304 are fixedly connected to the middle of the inner wall of the fixed mounting plate 301.

[0037] In this embodiment, the side cleaning brush 303 and the center cleaning brush 304 can use their own structure in conjunction with the rotation of the turbulence component 2 to clean the dust, preventing dust accumulation and affecting the effect of subsequent use.

[0038] Working principle: The device is installed inside the heat exchanger through the first connection port 1 and the second connection port 6. When the heat exchanger receives convective input, the structure of the turbulence component 2 is used to turbulent the flow. The turbulence component 2 uses its own streamlined structure to reduce flow separation and reduce form drag. It also adopts a structure with large gaps to form a discrete layout, allowing the fluid to recover pressure between the turbulence units and avoid continuous blockage. At the same time, it works with the internal structure to keep the turbulence plate body 208 active, using large-scale vortices to mix hot and cold fluids, achieving maximum heat transfer gain with minimal resistance. During operation, the dust removal component 3 continuously cleans the dust from the turbulence plate to prevent blockage and further improve the turbulence effect of the device. The motor stabilizing plate 4 can provide a stable foundation for the motor inside the turbulence component 2. The connecting stabilizing plate 5 can help the motor stabilizing plate 4 to be installed on top of the surface of the turbulence component 2, thereby improving the stability of the motor stabilizing plate 4.
