Description

Technical Field

[0002] With the widespread use of mechanical equipment such as industrial equipment and diesel generators, the cleaning and maintenance of heat exchangers, key components of these devices, are receiving increasing attention. The primary function of a heat exchanger is to cool or heat fluids through heat exchange, ensuring efficient operation of the equipment. However, during actual use, dust, dirt, grease, and other contaminants easily accumulate on the heat exchanger's surface, reducing heat exchange efficiency and potentially causing equipment failure. Therefore, timely and effective heat exchanger cleaning has become a crucial issue to ensure stable equipment operation.

[0003] Currently, the majority of heat exchanger cleaning technologies on the market utilize the following methods: 1. Manual cleaning; 2. Installing a vibration device on the heat exchanger surface to shake dirt off the heat exchanger surface using high-frequency vibrations. While existing cleaning technologies can address the problem of heat exchanger surface fouling to a certain extent, they still suffer from low efficiency, incomplete cleaning, and a high reliance on manual labor. Furthermore, due to the limitations of these cleaning methods, many equipment require frequent manual intervention or maintenance downtime, resulting in low production efficiency and increased operating and maintenance costs.

[0004] Therefore, there is an urgent need for a new heat dissipation generator that can operate stably for a long time while improving the cleaning efficiency of the radiator and reducing manual intervention. Summary of the Invention

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0028] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0030] Conventional generators with heat dissipation structures mainly adopt an air-cooling structure, which uses the engine to drive the cooling fan to rotate and pass hot water through the coil or tube structure. The fan rotates to provide cooling airflow through the coil or tube structure and take away the heat. Since the coil or tube structure has a large surface area, dust, moisture and other debris in the airflow are easily attached to the surface of the coil or tube structure. Over time, it is easy to cause a large amount of dirt to accumulate on the surface of the heat exchange structure, reducing the heat exchange efficiency. Therefore, the surface of the heat exchange structure needs to be cleaned frequently. Due to the complex structure of the tube, manual cleaning is difficult, and automated cleaning is even more difficult. Therefore, the coil structure has better application prospects as an easy-to-clean heat dissipation structure. In some conventional solutions, a vibration structure is set on the surface of the coil structure to use vibration to clean the attached dirt. The coils are usually arranged in a vertical array. After the dirt on the upper side falls, it will still fall to the surface of the coil below. Therefore, this cleaning method has a good effect in the early stage. After long-term use, there will be a serious problem of dirt accumulation. Some existing solutions have a movable cleaning device installed on the surface of the coil, which is used to gradually clean the coil along its extension direction. Although this can overcome the problem of dirt accumulation, due to the long length of the coil, this cleaning method is inefficient. In addition, in order to keep the surface clean, this cleaning device needs to be kept running at all times.

[0031] In view of the problems of unreasonable design of the current radiator cleaning structure and low cleaning efficiency, the inventors proposed a heat dissipation generator solution with higher feasibility and higher cleaning efficiency.

[0032] like Figure 1 As shown, combined Figure 2-7The heat dissipation generator of the present invention includes: an engine 1, a generator 2, a fan 3 and a heat dissipation water tank 4. The engine 1 is connected to the generator 2 by power transmission. The engine 1 drives the fan to rotate 3. The fan 3 is arranged opposite the heat dissipation water tank 4. The heat dissipation water tank 4 is used to cool the engine 1. The heat dissipation water tank 4 includes: a frame 41, an upper water tank 42, a lower water tank 43, a cooling pipe 44, a cleaning roller brush 45 and a driving device 46. The upper water tank 42 is fixed above the frame 41, and the lower water tank 43 is fixed below the frame 41. A plurality of cooling pipes 44 are arranged in a parallel and spaced array in the middle of the frame 41. Both ends of the cooling pipes 44 are rotatably connected to the frame 41. The openings at both ends of the cooling pipes 44 are respectively connected to the upper water tank 42 and the lower water tank 43. A cleaning roller brush 45 is arranged in parallel and spaced between adjacent two cooling pipes 44. The cleaning roller brush 45 is rotatably connected to the frame 41. The bristles on the surface of the cleaning roller brush 45 contact the surfaces of the two adjacent cooling pipes 44. The driving device 46 can drive the cooling pipes 44 and the cleaning roller brush 45 to rotate synchronously.

[0033] In the above embodiment, two adjacent cooling tubes 44 are grouped as a group, and only one cleaning roller brush 45 is provided in each group structure. In daily use, the cooling tube 44 serves as the main heat exchange structure, and the cooling air flow will flow through the gaps between the cooling tubes 44 and between the cooling tubes 44 and the cleaning roller brush 45 and take away heat to achieve the purpose of heat dissipation. When there is dirt accumulation on the surface of the cooling tube 44 that needs to be cleaned, the driving device 46 drives the cooling tube 44 and the cleaning roller brush 45 to rotate in the same direction at the same time. At this time, the cleaning roller brush 45 can simultaneously brush the surfaces of the cooling tubes 44 on both sides in opposite directions, thereby achieving the purpose of rapid cleaning. Since the bristles on the surface of the cleaning roller brush 45 are not in contact with the surface of the cooling tube 44 at all times, the dirt on the bristles is more easily driven away and dropped by the cooling air flow after cleaning. This structure can achieve the cleaning purpose by driving the cleaning roller brush 45 to rotate when cleaning is needed, and can keep the cooling tube 44 and the cleaning roller brush 45 stationary when cleaning is not needed.

[0034] The above cleaning method and cleaning mode are easy to implement, have good cleaning effect, high cleaning efficiency, low energy consumption in the cleaning process, simple and reliable structure, and good cleaning effect.

[0035] It should be understood that the cooling pipe 44 can maintain a dynamic seal with the frame 41 during its rotational connection with the frame 41, for example, by employing a groove seal or labyrinth seal at the rotational connection. The cooling pipe 44 is used to transport water from the upper water tank 42 to the lower water tank 43. In the above embodiment, the cooling pipes 44 are all arranged horizontally, with multiple cooling pipes 44 arranged in a vertically spaced array.

[0036] In some embodiments, the cooling pipe 44 is a curved structure, and the cooling pipe 44 includes a straight pipe 441 and a curved pipe 442. The axis of the curved pipe 442 is a sine curve. The straight pipe 441 is connected at both ends of the curved pipe 442, and the axis of the straight pipe 441 coincides with the baseline of the sine curve.

[0037] In the above embodiments, the curved cooling pipe 44 can provide a longer pipeline path, thereby facilitating an increase in surface area and improving heat dissipation efficiency.

[0038] In some embodiments, the axis of the cleaning roller brush 45 and the axis of the cooling tube 44 are the same in shape and size.

[0039] In the above embodiment, along the vertical direction, the distance between the axis of the cleaning roller brush 45 and the axis of the cooling tube 44 are equal. At this time, when the cleaning roller brush 45 and the cooling tube 44 rotate at the same angular velocity, the distance between the two will remain constant, thereby avoiding interference and collision during the rotation process.

[0040] In some embodiments, at least one row of bristles 451 is provided on the surface of the cleaning roller brush 45 along the axial direction.

[0041] In the above embodiment, the bristles 451 are used to scrub and clean the surface of the cooling tube 44 .

[0042] In some embodiments, the bristles 451 are spirally twisted along the axis of the cleaning roller brush 45 .

[0043] In the above embodiment, the twisted bristles 451 are used to clean the surface of the cooling tube 44 with fewer bristles 451 , and the twisted bristles 451 are conducive to forming gaps between the bristles 451 , which is beneficial to the circulation of air.

[0044] In some embodiments, the driving device 46 includes a driving motor 461, a driving gear 462, a rack 463 and a driven gear 464. The rack 463 is linearly slidably installed on the surface of the frame 41. The sliding direction of the rack 463 is the same as the array installation direction of the cooling tube 44. The driving motor 461 is fixed on the surface of the frame 41. The driving motor 461 is connected to the driving gear 462 for transmission. The driving gear 462 and the rack 463 are engaged. The end of the cooling tube 44 is coaxially installed with the driven gear 464. The end of the cleaning roller brush 45 is coaxially installed with the driven gear 464, and the driven gear 464 is engaged with the rack 463.

[0045] In the above embodiment, the driving device 46 is used to drive the cooling pipe 44 and the cleaning roller brush 45 to rotate simultaneously. As one of the feasible methods, the rotation drive is performed by meshing the rack and pinion with each other, which has the effects of simple driving method, simple structure and easy maintenance. Since the cooling pipe 44 and the cleaning roller brush 45 can achieve good surface cleaning after rotating one circle, the rack and pinion meshing structure is more in line with the use requirements. Moreover, when the above structure is adopted, the cooling pipe 44 and the cleaning roller brush 45 can be locked at an angle, and the purpose of adjusting different heat dissipation rates can be achieved.

[0046] In some embodiments, a first cavity 411 and a second cavity 412 are respectively provided on both sides of the frame 41, the first cavity 411 is connected to the same end of the cooling pipe 44, the second cavity 412 is connected to the other end of the cooling pipe 44, the first cavity 411 is connected to the upper water tank 42, and the second cavity 412 is connected to the lower water tank 43.

[0047] In the above embodiment, the first cavity 411 and the second cavity 412 are respectively used to communicate with the inlet and outlet of the cooling pipe 44 to facilitate the collection and dispersion of water flow.

[0048] In some embodiments, an overflow port 421 is provided on the top of the upper water tank 42 .

[0049] In the above embodiment, the overflow port 421 is used to overflow the excess water in the water tank 42 , and the overflow port 421 can also realize the replacement of cooling water.

[0050] In some embodiments, a water inlet 422 is provided on the side of the upper water tank 42, and a water outlet 431 is provided on the side of the lower water tank 43. The water inlet 422 is connected to the heat dissipation cavity outlet of the engine 1, and the water outlet 431 is connected to the heat dissipation cavity inlet of the engine 1.

[0051] In the above embodiment, the water inlet 422 is used to receive high-temperature water from the engine 1 , and the water outlet 431 is used to transport the cooled water to the heat dissipation cavity of the engine 1 .

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
