Description

Technical Field

[0001] This utility model belongs to the field of heat exchange, specifically relating to a modular multi-medium heat exchanger. Background Technology

[0002] Heat exchangers, as a type of heat exchange device, are commonly used in industrial production to heat or cool fluids. However, most existing heat exchangers can only dissipate heat to one medium at a time to improve heat exchange efficiency; but when industrial production requires heating or cooling multiple fluids, multiple heat exchangers are needed to meet the demand, increasing production costs.

[0003] In existing technologies, such as patent document CN222317777U, an air-cooled heat exchanger is disclosed. By adding a fan assembly to the air guide shroud and leaving the central area of ​​the air-cooled cooler empty, the airflow around the air-cooled cooler is changed, achieving simultaneous internal and external cooling, thereby enhancing heat dissipation efficiency. However, this heat exchanger can only be used for heat exchange of one medium at a time. When heat exchange of multiple media is required simultaneously, multiple heat exchangers are needed, increasing heat exchange costs. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model proposes a modular multi-medium heat exchanger. By placing different heat exchange modules near different air outlets, it is possible to exchange heat with multiple media simultaneously, thereby achieving the effect of heating or cooling multiple media at the same time. Furthermore, since different heat exchange modules are placed near different air outlets, heating modules at different temperatures can also heat the gas flowing out of different air outlets to obtain gas at different temperatures.

[0005] This utility model is implemented as follows: A modular multi-medium heat exchanger includes a frame, with an air inlet, a first air outlet, and a second air outlet respectively provided at the bottom, top, and periphery of the frame. An air supply device is provided at the air inlet, and the air inlet is connected to the air inlet end of the air supply device, so that the airflow in the frame flows from bottom to top. The frame also has a heat exchange chamber, which is located above the air supply device, and the bottom of the heat exchange chamber is connected to the air supply end of the air supply device. The first air outlet is located at the top of the heat exchange chamber, and the second air outlet is located on the periphery of the heat exchange chamber.

[0006] The heat exchange chamber is further equipped with multiple heat exchange modules, including a first heat exchange module arranged horizontally and multiple second heat exchange modules arranged vertically in parallel. The first heat exchange module is close to the first air outlet, and the second heat exchange modules are close to the second air outlet. The first heat exchange module and the multiple second heat exchange modules can exchange heat with multiple media simultaneously to achieve the effect of heating or cooling multiple media at the same time. At the same time, since different heating modules are close to different air outlets, different heating modules can reach different temperatures through media of different temperatures. Thus, when the gas in the heat exchange chamber flows out from different air outlets, it is heated to different temperatures, which can simultaneously meet different heating requirements.

[0007] The heat exchange medium in the first heat exchange module and the plurality of second heat exchange modules is of at least two kinds.

[0008] Preferably, the first heat exchange module is provided with a plurality of first heat exchange tubes, and the second heat exchange module is provided with a plurality of second heat exchange tubes. The plurality of first heat exchange tubes / second heat exchange tubes are connected end to end in sequence through arc-shaped bends to form a reciprocating and meandering first heat exchange unit / second heat exchange unit, which increases the thermal contact area of ​​the first heat exchange module / second heat exchange module and thus improves the heat exchange efficiency of the first heat exchange module / second heat exchange module.

[0009] Specifically, both the first and second heat exchange tubes include a hollow tube body with multiple fins embedded around its periphery. These fins extend along the direction of the first / second heat exchange tube. The fins further increase the thermal contact area between the first and second heat exchange tubes, thereby increasing the thermal contact area between the first and second heat exchange modules and further improving their heat exchange efficiency.

[0010] Specifically, the fins are made of aluminum alloy. Aluminum alloy has excellent thermal conductivity and is lightweight, which can reduce the weight of the first and second heat exchange tubes while ensuring heat dissipation effect, thereby reducing the weight of the first and second heat exchange modules and making them easier to install, thus improving the ease of installation. At the same time, it can also lower the center of gravity of the heat exchanger, making it less likely to tip over and improving the safety of the heat exchanger.

[0011] Specifically, multiple first heat exchange tubes / second heat exchange tubes are arranged side by side to form multiple first heat exchange meshes / second heat exchange meshes facing the first air outlet / second air outlet. The multiple first heat exchange meshes / second heat exchange meshes further increase the thermal contact area of ​​the first heat exchange module / second heat exchange module, thereby further improving the heat exchange efficiency of the first and second heat exchange modules.

[0012] Specifically, adjacent first / second heat exchange meshes are arranged in an alternating pattern, causing the first / second heat exchange tubes of adjacent first / second heat exchange meshes to be misaligned. This alternating arrangement prevents gas from flowing directly from the gaps in the heat exchange meshes to the air outlet, which would reduce the heat exchange efficiency and improve the reliability of the first and second heat exchange modules.

[0013] Specifically, the diameter of the first heat exchange tube / second heat exchange tube is larger than the mesh size of the first heat exchange mesh / second heat exchange mesh (the gap between adjacent heat exchange tubes on the heat exchange mesh), so that the projections of the first heat exchange tubes / second heat exchange tubes of adjacent first heat exchange meshes / second heat exchange meshes overlap on the projection plane parallel to the first heat exchange mesh / second heat exchange mesh. This prevents gaps from remaining in the misaligned first heat exchange tubes / second heat exchange tubes, further improving the reliability of the first heat exchange tubes and second heat exchange tubes.

[0014] Preferably, both the medium inlet and medium outlet ends of the first and second heat exchange modules are provided with connecting flanges, and the connecting flanges are also provided with positioning parts. The positioning parts are used to position the first or second heat exchange module when it is connected to external equipment, thereby improving the connection accuracy of the first and second heat exchange modules when connected to external equipment.

[0015] Preferably, the number of air supply devices is two.

[0016] Preferably, the bottom of the frame is also provided with multiple support feet, which create a gap between the air supply device and the ground. After the heat exchanger has been used for a period of time, dust will accumulate on the ground. When a gap is formed between the air supply device and the ground, it not only reduces the dust mixed in when the air supply device delivers air, but also makes it easier for staff to clean the dust, thereby preventing dust accumulation inside the first and second heat exchange modules and improving the stability of the first and second heat exchange modules.

[0017] The beneficial effects of this utility model are:

[0018] This invention proposes a modular multi-medium heat exchanger. By placing different heat exchange modules near different air outlets, it can simultaneously exchange heat with multiple media to achieve the effect of heating or cooling multiple media at the same time. On the other hand, since different heat exchange modules are close to different air outlets, heating modules at different temperatures can also heat the gas flowing out of different air outlets. Thus, the gas in the heat exchange chamber is heated to different temperatures when it flows out of different air outlets, which can simultaneously meet different heating needs.

[0026] 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 a part of the embodiments of the present utility model, and not all of them. 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.

[0027] like Figures 1-5 As shown, a modular multi-medium heat exchanger includes a frame 1. The frame 1 has an air inlet 13, a first air outlet 14, and a second air outlet 15 at its bottom, top, and periphery, respectively. An air supply device 2 is provided at the air inlet 13 and is connected to the air inlet end of the air supply device 2, so that the airflow in the frame 1 flows from bottom to top. The frame 1 also has a heat exchange chamber 11, which is located above the air supply device 2 and its bottom is connected to the air supply end of the air supply device 2. The first air outlet 14 is located at the top of the heat exchange chamber 11, and the second air outlet 15 is located on the periphery of the heat exchange chamber 11.

[0028] In this embodiment, the bottom of the frame 1 is also provided with multiple support feet 12, which create a gap between the air supply device 2 and the ground. After the heat exchanger has been used for a period of time, dust will accumulate on the ground. When a gap is formed between the air supply device 2 and the ground, it not only reduces the dust mixed in when the air supply device 2 delivers air, but also makes it easier for staff to clean the dust, thereby preventing dust accumulation inside the first heat exchange module 3 and the second heat exchange module 4, and improving the stability of the first heat exchange module 3 and the second heat exchange module 4.

[0029] In this embodiment, the air supply device 2 is a fan, and there are 2 of them.

[0030] The heat exchange chamber 11 is also equipped with multiple heat exchange modules, including a first heat exchange module 3 arranged horizontally and multiple second heat exchange modules 4 arranged vertically in parallel. The first heat exchange module 3 is close to the first air outlet 14, and the second heat exchange modules 4 are close to the second air outlet 15. The first heat exchange module 3 and the multiple second heat exchange modules 4 can exchange heat with multiple media simultaneously to achieve the effect of heating or cooling multiple media at the same time. At the same time, since different heating modules are close to different air outlets, different heating modules can reach different temperatures through media of different temperatures. Thus, when the gas in the heat exchange chamber 11 flows out from different air outlets, it is heated to different temperatures, which can simultaneously meet different heating requirements.

[0031] The heat exchange medium in the first heat exchange module 3 and the multiple second heat exchange modules 4 is of at least two kinds.

[0032] In this embodiment, the first heat exchange module 3 is provided with a plurality of first heat exchange tubes 31, and the second heat exchange module 4 is provided with a plurality of second heat exchange tubes 41. The plurality of first heat exchange tubes 31 / second heat exchange tubes 41 are connected end to end in sequence through arc-shaped bends to form a reciprocating and meandering first heat exchange unit / second heat exchange unit, which increases the thermal contact area of ​​the first heat exchange module 3 / second heat exchange module 4, thereby improving the heat exchange efficiency of the first heat exchange module 3 / second heat exchange module 4.

[0033] Specifically, both the first heat exchange tube 31 and the second heat exchange tube 41 include a hollow tube body 311, with multiple fins 312 embedded around the periphery of the tube body 311. These fins 312 extend along the direction of the first heat exchange tube 31 / second heat exchange tube 41. The fins 312 further increase the thermal contact area between the first heat exchange tube 31 and the second heat exchange tube 41, thereby further increasing the thermal contact area between the first heat exchange module 3 and the second heat exchange module 4, and further improving the heat exchange efficiency of the first heat exchange module 3 and the second heat exchange module 4.

[0034] Specifically, the fins 312 are made of aluminum alloy. Aluminum alloy has excellent thermal conductivity and is lightweight, which can reduce the weight of the first heat exchange tube 31 and the second heat exchange tube 41 while ensuring heat dissipation effect, thereby reducing the weight of the first heat exchange module 3 and the second heat exchange module 4. This makes the first heat exchange module 3 and the second heat exchange module 4 easier to install and improves the installation convenience of the first heat exchange module 3 and the second heat exchange module 4. At the same time, it can also lower the center of gravity of the heat exchanger, making the heat exchanger less likely to tip over and improving the safety of the heat exchanger.

[0035] Specifically, multiple first heat exchange tubes 31 and second heat exchange tubes 41 are arranged side by side to form multiple first heat exchange meshes and second heat exchange meshes that face the first air outlet 14 and the second air outlet 15. These multiple first heat exchange meshes and second heat exchange meshes further increase the thermal contact area of ​​the first heat exchange module 3 and the second heat exchange module 4, thereby further improving the heat exchange efficiency of the first heat exchange module 3 and the second heat exchange module 4.

[0036] Specifically, adjacent first / second heat exchange meshes are arranged in an alternating pattern, causing the first heat exchange tubes 31 and 41 of adjacent first / second heat exchange meshes to be misaligned. This alternating arrangement prevents gas from flowing directly from the gaps in the heat exchange meshes to the air outlet, which would reduce the heat exchange efficiency and improve the reliability of the first heat exchange module 3 and the second heat exchange module 4.

[0037] Specifically, the diameter of the first heat exchange tube 31 / second heat exchange tube 41 is larger than the mesh size of the first heat exchange mesh / second heat exchange mesh (the gap between adjacent heat exchange tubes on the heat exchange mesh), so that the projections of the first heat exchange tubes 31 / second heat exchange tubes 41 of adjacent first heat exchange meshes overlap on the projection plane parallel to the first heat exchange mesh / second heat exchange mesh, thereby preventing gaps from still existing in the misaligned first heat exchange tubes 31 / second heat exchange tubes 41, and further improving the reliability of the first heat exchange tubes 31 and second heat exchange tubes 41.

[0038] In this embodiment, both the medium inlet end and the medium outlet end of the first heat exchange module 3 and the second heat exchange module 4 are provided with connecting flanges 32. The connecting flanges 32 are also provided with positioning parts. The positioning parts are used to position the first heat exchange module 3 or the second heat exchange module 4 when connected to external equipment, thereby improving the connection accuracy of the first heat exchange module 3 and the second heat exchange module 4 when connected to external equipment.

[0039] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
