Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and specifically to a heat exchanger with a cleaning device. Background Technology

[0002] In the field of heat exchanger technology, parallel flow heat exchange technology has been widely used in many fields such as refrigeration, HVAC, and industrial cooling due to its core advantages of compact structure and high heat transfer efficiency.

[0003] Most mainstream parallel flow heat exchangers currently employ a straight tube array design. While this design is suitable for large-scale production and assembly, its core heat transfer component, the fins, suffers from significant scaling and fouling issues, becoming a key bottleneck restricting stable heat transfer efficiency. Especially in V-shaped parallel flow heat exchangers, baffle structures are typically installed on both sides to achieve the design goals of improving heat transfer efficiency, suppressing condensation, and reducing fluid pressure drop.

[0004] Because finned structures are prone to dust accumulation and clogging, leading to a sharp drop in heat exchange efficiency, fins are typically designed with a dense arrangement to increase the heat transfer area. While this method enhances heat transfer potential, it also easily attracts dust and impurities from the air, causing them to accumulate. Dust accumulation directly blocks airflow channels, significantly weakening the heat exchanger's heat transfer capacity and thus affecting the overall performance of the heat exchange equipment. Furthermore, cleaning finned fouling is time-consuming and labor-intensive, often requiring disassembly of the equipment for deep cleaning, resulting in prolonged downtime and significant disruptions to industrial production or civilian applications.

[0005] In addition, while the baffles on both sides of the V-type parallel flow heat exchanger can optimize heat exchange conditions, they also create a relatively closed space inside the heat exchanger, which severely limits the accessibility of cleaning operations. When scale forms inside the heat exchanger due to long-term operation, operators cannot effectively clean or maintain the closed internal area. This will not only continuously reduce heat transfer efficiency, but also accelerate the corrosion and aging of internal components, ultimately shortening the service life of the heat exchanger and negatively impacting the operational stability and overall performance of the entire unit.

Detailed Implementation

[0029] The present invention will be further described in conjunction with the following embodiments.

[0030] Depend on Figures 1 to 5 As can be seen, the heat exchanger with a cleaning device described in this embodiment includes a support plate 1; a first fin 21 is obliquely arranged on the top of one side of the support plate 1; and a second fin 22 is obliquely arranged on the top of the other side of the support plate 1.

[0031] The cleaning device includes a bottom spray pipe 3 arranged along the length of the support plate 1; the bottom spray pipe 3 is provided with a plurality of first top spray pipes 4 in the direction of the inner side of the first fin 21; the bottom spray pipe 3 is provided with a plurality of second top spray pipes 5 in the direction of the inner side of the second fin 22.

[0032] The bottom spray pipe 3 is provided with a bottom nozzle 31; the first top spray pipe 4 is provided with a first top nozzle 41; and the second top spray pipe 5 is provided with a second top nozzle 51.

[0033] Specifically, the heat exchanger with cleaning device described in this embodiment, by setting a bottom spray pipe 3, a first top spray pipe 4, and a second top spray pipe 5 inside the heat exchanger, allows the bottom spray pipe 3 to directionally remove residual dirt from the support plate 1 through the bottom nozzle 31, the first top spray pipe 4 to rinse the first fin 21 through the first top nozzle 41, and the second top spray pipe 5 to rinse the second fin 22 through the second top nozzle 51. This solves the problem of cleaning blind spots caused by the closed structure and the tilt of the first fin 21 and the second fin 22 in traditional V-type heat exchangers, and achieves full coverage of the inner side of the first fin 21, the inner side of the second fin 22, and the support plate 1, avoiding local scale buildup that affects heat exchange efficiency. At the same time, cleaning can be started without disassembling the equipment, reducing downtime maintenance time.

[0034] In this embodiment, a heat exchanger with a cleaning device is provided, wherein the bottom spray pipe 3 is located on the top of the support plate 1; the length direction of the bottom spray pipe 3 is parallel to the plane on which the support plate 1 is located.

[0035] The length direction of the first top spray pipe 4 is parallel to the arrangement direction of the first fins 21; the length direction of the second top spray pipe 5 is parallel to the arrangement direction of the second fins 22.

[0036] Specifically, through the above-mentioned settings, this embodiment can ensure that the bottom spray pipe 3, the first top spray pipe 4, and the second top spray pipe 5 can extend into contact with the support plate 1, the first fin 21, and the second fin 22, thereby maximizing the coverage of the bottom nozzle 31, the first top spray pipe 4, and the second top spray pipe 5 and effectively improving the cleaning effect on the heat exchanger.

[0037] The heat exchanger with a cleaning device described in this embodiment has multiple bottom nozzles 31, which are equally spaced on the bottom spray pipes 3; multiple first top nozzles 41, which are equally spaced on the first top spray pipes 4; and multiple second top nozzles 51, which are equally spaced on the second top spray pipes 5. Specifically, this embodiment, through the above arrangement, can ensure uniform spray intensity per unit area.

[0038] The first top spray pipe 4 and the second top spray pipe 5 are alternately arranged along the length of the bottom spray pipe 3. This arrangement avoids the first top spray pipe 4 and the second top spray pipe 5 on both sides from overlapping at the same position, making full use of the length space of the bottom spray pipe 3 and preventing the spray range of the first top nozzle 41 and the second top nozzle 51 from blocking each other.

[0039] This embodiment describes a heat exchanger with a cleaning device, wherein the bottom nozzle 31 is a direct-fire nozzle; the first top nozzle 41 and the second top nozzle 51 are both atomizing nozzles. Specifically, the support plate 1 needs to be cleaned of stubborn deposits. The direct-fire nozzle has a stronger water flow impact force and can directionally rinse the deposits. The first fin 21 and the second fin 22 have a dense structure and are made of thin material. The atomizing nozzle can form a dispersed and gentle water mist, avoiding water flow impact damage to the fins. At the same time, the water mist can penetrate the gaps between the fins to clean fine dust.

[0040] This embodiment describes a heat exchanger with a cleaning device. The support plate 1 is provided with a fixed seat 11; the bottom spray pipe 3 is fitted with a clamp 32; the bottom spray pipe 3 is detachably connected to the fixed seat 11 via the clamp 32. This arrangement facilitates the detachable connection between the bottom spray pipe 3 and the support plate 1.

[0041] This embodiment describes a heat exchanger with a cleaning device. Both ends of the support plate 1 are provided with side plates 6. The first fin 21 and the second fin 22 are both disposed between the two side plates 6. The side plates 6 are provided with viewing holes, and the viewing holes are fitted with transparent plates 61. Specifically, this embodiment uses viewing holes on the closed side plates 6 and adds transparent plates 61 (which can be acrylic plates) to allow operators to observe the scale buildup on the internal fins and support plate 1 without disassembling the equipment, thus visually determining whether cleaning is necessary and assessing the cleaning effect.

[0042] This embodiment describes a heat exchanger with a cleaning device. The first fin 21 is equipped with a first top pressure sensor electrically connected to a first top nozzle 41; the second fin 22 is equipped with a second top pressure sensor electrically connected to a second top nozzle 51; and the support plate 1 is equipped with a bottom pressure sensor electrically connected to a bottom nozzle 31. The first, second, and bottom pressure sensors are not shown in the figure. Specifically, this embodiment uses pressure sensors to monitor the fouling status of the first fin 21, second fin 22, and support plate 1: when fouling increases on the first fin 21, second fin 22, or support plate 1, the resistance to fluid flow increases, and the pressure value exceeds a preset threshold. The corresponding pressure sensor then sends a signal, automatically activating the corresponding nozzle. This setup enables automated and precise cleaning, eliminating the need for manual monitoring to assess fouling. Each pressure sensor can monitor and trigger corresponding cleaning actions in real time, avoiding premature cleaning that wastes resources or excessive cleaning. Furthermore, only the nozzles in the areas requiring cleaning are activated, reducing energy and water consumption.

[0043] This embodiment describes a heat exchanger with a cleaning device, which further includes a water tank 71 and a water pump 72. A first inlet pipe 73 is provided between one end of the water pump 72 and the water tank 71; a second inlet pipe 74 is provided between the other end of the water pump 72 and the bottom spray pipe 3. In this embodiment, the water tank 71 stores clean water, and the water pump 72 serves as a power source, sequentially transporting the water in the water tank 71 through the first inlet pipe 73, the water pump 72, and the second inlet pipe 74 to the bottom spray pipe 3, and then distributing it to the top spray pipes and individual nozzles.

[0044] This embodiment describes a heat exchanger with a cleaning device. One side of the support plate 1 has a first water receiving tray 81; the other side of the support plate 1 has a second water receiving tray 82; a drain pipe 9 is provided between the first water receiving tray 81 and the water tank 71, and between the second water receiving tray 82 and the water tank 71; the drain pipe 9 is equipped with a filter 91. Specifically, the cleaned wastewater or condensate flows down through the first fin 21, the second fin 22, and the support plate 1, is collected by the first water receiving tray 81 and the second water receiving tray 82, and then transported back to the water tank 71 through the drain pipe 9; when the wastewater flows through the drain pipe 9, the filter 91 intercepts dirt and impurities in the water, preventing dirty water from directly flowing back to the water tank 71 and causing secondary pollution.

[0045] This embodiment describes a heat exchanger with a cleaning device. A first inclined guide plate 83 is provided between the first water receiving tray 81 and the support plate 1; the first inclined guide plate 83 is located at the bottom of the first fin 21; a second inclined guide plate 84 is provided between the second water receiving tray 82 and the support plate 1; the second inclined guide plate 84 is located at the bottom of the second fin 22. Specifically, the first inclined guide plate 83 and the second inclined guide plate 84 utilize gravity to guide the clean wastewater or condensate flowing from the first fin 21, the second fin 22, and the support plate 1 to the first water receiving tray 81 and the second water receiving tray 82.

[0046] The heat exchanger with a cleaning device described in this embodiment further includes a first switch 62 and a second switch 63; the bottom nozzle 31 is electrically connected to the first switch 62; the first top nozzle 41 and the second top nozzle 51 are respectively electrically connected to the second switch 63; wherein the first switch 62 and the second switch 63 can be installed on the side plate 6; the first switch 62 and the second switch 63 can both be rocker switches.

[0047] Specifically, in addition to automatically controlling each nozzle through various pressure sensors, operators can also manually control the opening and closing of the bottom nozzle 31, the first top nozzle 41, and the second top nozzle 51 by controlling the first switch 62 and the second switch 63 respectively. When maintenance personnel are inspecting, they can observe the dust condition inside the heat exchanger through the transparent plate 61 and manually open the corresponding nozzles to achieve zoned cleaning.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
