Description

Technical Field

[0001] This invention relates to the field of marine radiator technology, and in particular to a self-cleaning marine radiator. Background Technology

[0002] Marine radiators are indispensable cooling devices in marine propulsion systems and auxiliary equipment. They are primarily used to cool equipment such as marine engines and generator sets that generate a large amount of heat during operation, ensuring stable operation within a suitable temperature range and preventing performance degradation, malfunctions, or even damage due to overheating. Structurally, marine radiators typically consist of core heat dissipation components, inlet and outlet water pipes, heat sinks, and a shell. The core heat dissipation components often utilize highly efficient heat exchange materials, such as copper, aluminum, and their alloys. These materials have excellent thermal conductivity, enabling rapid heat transfer. The heat sinks further enhance heat dissipation efficiency by increasing the contact area with air or coolant.

[0003] A combined marine steam radiator with application number CN202222128315.7 includes a coil. A return flow element is inclinedly arranged below one side of the coil. One end of the return flow element is connected to the coil. An air inlet pipe is arranged above the return flow element. One end of the air inlet pipe enters the interior of the return flow element from bottom to top. The return flow element is a tubular structure, and a water storage tank is provided at the bottom of the tubular structure. The water storage tank is located below the air inlet pipe. A drainage component is provided at the bottom of the return flow element. A baffle is provided on the inner wall of the return flow element. This utility model sets up a return flow element located between the air inlet pipe and the coil. Steam enters the coil through the return flow element. Some condensate is collected at the bottom of the return flow element through the inclined return flow element, which avoids the accumulated condensate from obstructing the smooth flow of steam. At the same time, the condensate in the water storage tank is discharged through the drainage component.

[0004] In practical use, because the engine cooling fan is installed behind the coolant tank and close to the engine, the installation space is relatively limited. The aforementioned patented structural design is overly complex and large in size, which is not conducive to radiator installation. Furthermore, once the structure suffers stress damage, the subsequent repair costs are high. Moreover, existing marine radiators have relatively limited functionality during operation, unable to adjust their operating status in real time according to temperature conditions in the actual operating environment, and cannot perform periodic self-cleaning, thus affecting their service life and heat dissipation efficiency. Therefore, this invention proposes a self-cleaning marine radiator to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a self-cleaning marine radiator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a self-cleaning marine radiator, comprising a radiator, a fan fixedly mounted on the rear side of the radiator, and a cleaner mounted on the front side of the radiator;

[0007] The radiator has a heat dissipation window in the middle, and multiple sets of heat dissipation aluminum fins are arranged inside the heat dissipation window. Cooling chambers are provided on both the left and right sides inside the radiator. A condenser tube connected to the multiple sets of heat dissipation aluminum fins is fixed inside the cooling chamber. The cooling chamber is filled with coolant, and the two ends of the condenser tube extend out of the radiator and are respectively provided with inlet pipe and outlet pipe. A ventilation channel is provided between two adjacent sets of heat dissipation aluminum fins.

[0008] The fan includes an isolation cover, which is fixed to the rear side wall of the radiator by fixing bolts. A drive motor is fixedly mounted on the isolation cover, and a mounting cylinder is fixedly mounted on the output end of the drive motor. Fan blades are evenly fixed on the outer side wall of the mounting cylinder.

[0009] Preferably, the radiator has a mounting hole in the middle of the rear side wall, and a protective ring is fixedly installed on the outside of the mounting hole. The mounting cylinder extends into the radiator, and the fan blades are embedded inside the protective ring.

[0010] Preferably, multiple sets of heat sink aluminum fins correspond to the fan, and the diameter of the fan blades is the same as the height of the heat sink aluminum fins.

[0011] Preferably, the cleaner includes slide rails fixed on the left and right side walls inside the heat dissipation window, two sets of slide rails with slide tracks, each set of slide tracks with a slide seat slidably mounted inside, the outer ends of the left and right sets of slide seats are fixed with cleaning scrapers, the cleaning scrapers are fitted to the outer side walls of the heat dissipation aluminum fins, and the top and bottom of the radiator cavity are fixed with electromagnet plates that match the cleaning scrapers.

[0012] Preferably, the cleaning scraper is configured in two sets, symmetrically arranged on the upper and lower sides inside the heat dissipation window, and each set of cleaning scrapers spans multiple sets of heat dissipation aluminum fins. Each set of electromagnet plates corresponds to each set of cleaning scrapers, and each set of cleaning scrapers is embedded with a magnetic strip that matches the electromagnet plate.

[0013] Preferably, the cleaner further includes scraping blocks fixed to the rear side wall of the cleaning scraper, and each set of scraping blocks is embedded in the ventilation channel, wherein the scraping blocks are rubber bags.

[0014] Preferably, an airbag is fixedly assembled between two sets of slide blocks in the same slide rail, and each set of airbags is connected to the scraper block through an air supply pipe.

[0015] Preferably, the size of the scraper block matches the ventilation channel, and the number of scraper blocks is twice the number of ventilation channels.

[0016] The technical effects and advantages of this invention are as follows:

[0017] 1. This invention fixes the fan to the heat sink using fixing bolts, which facilitates later inspection and maintenance, reduces maintenance costs, and has a high degree of integration between the fan and the heat sink, occupying little installation space. Furthermore, the fan is embedded inside the heat sink, which can directly blow heat off the heat sink fins, accelerating the dissipation of heat and improving the heat dissipation effect. In addition, multiple sets of heat sink fins correspond to the fan, and the diameter of the fan blades is the same as the height of the heat sink fins. In this way, when the fan rotates, the airflow generated can pass through multiple sets of heat sink fins well, accelerating the diffusion of heat.

[0018] 2. This invention integrates a cleaner on the radiator, which can clean the deposits on the surface of the aluminum fins, thereby clearing blockages and achieving self-cleaning of the radiator. Specifically, when the electromagnet plate is energized, it generates a magnetic repulsion force on the cleaning scraper, pushing the scraper to move on the surface of the aluminum fins. Simultaneously, the slide moves within the slide rail. When the two sets of cleaning scrapers move towards each other, the scrapers clean the aluminum fins, while the airbags between the slides are simultaneously compressed. This causes the gas inside the airbags to be introduced into the scraper blocks through the air supply pipe, causing the scraper blocks to expand. Thus, when the cleaning scrapers move, they can simultaneously drive multiple sets of scraper blocks to move, cleaning debris inside the ventilation channels and preventing impurities from accumulating inside the ventilation channels and affecting airflow.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 7 As shown, this embodiment discloses a self-cleaning marine radiator, including a radiator 10, a fan 20 fixedly mounted on the rear side of the radiator 10, and a cleaner 30 mounted on the front side of the radiator 10. In actual use, the radiator 10 is fixed on the front side of the engine, and the fan 20 is used to dissipate heat from the radiator 10. At the same time, the cleaner 30 can clean the radiator 10 to ensure the heat dissipation performance of the radiator 10.

[0029] Please see Figures 1-4 The radiator 10 has a heat dissipation window 12 in the middle, and multiple sets of heat dissipation aluminum fins 13 are arranged inside the heat dissipation window 12. Cooling chambers 11 are provided on both the left and right sides inside the radiator 10. Condensation pipes 14 that communicate with the multiple sets of heat dissipation aluminum fins 13 are fixed inside the cooling chambers 11. The cooling chambers 11 are filled with coolant, and the two ends of the condenser pipes 14 extend out of the radiator 10 and are respectively provided with liquid inlet pipes 15 and liquid outlet pipes 16. A ventilation channel 17 is provided between two adjacent sets of heat dissipation aluminum fins 13.

[0030] In actual use, the heat dissipation window 12 can effectively ensure air circulation, the heat dissipation aluminum fins 13 can ensure the thermal conductivity of the radiator 10, and the coolant built into the cooling chamber 11 can complete the heat exchange of the radiator 10. Moreover, the condenser pipe 14 can realize the flow of coolant between the heat dissipation aluminum fins 13, which facilitates the absorption of heat on the heat dissipation aluminum fins 13 through the coolant. In addition, the ventilation channel 17 between the heat dissipation aluminum fins 13 can ensure air circulation, which facilitates the heat dissipation operation of the heat dissipation aluminum fins 13 through air flow.

[0031] Please see Figure 3 and Figure 6 , Figure 7The fan 20 includes an isolation cover 22, which is fixed to the rear side wall of the radiator 10 by fixing bolts 21. A drive motor 23 is fixedly mounted on the isolation cover 22, and a mounting cylinder 24 is fixedly mounted on the output end of the drive motor 23. Fan blades 25 are evenly fixed on the outer side wall of the mounting cylinder 24. When the drive motor 23 works, it drives the fan blades 25 on the mounting cylinder 24 to rotate, thereby realizing air circulation and facilitating the fan 20 to complete the heat dissipation work of the radiator 10. Moreover, the fan 20 is fixed to the radiator 10 by fixing bolts 21, which facilitates later inspection and maintenance and reduces maintenance costs.

[0032] A mounting hole is provided in the middle of the rear side wall of the radiator 10, and a protective ring 18 is fixedly installed on the outside of the mounting hole. The mounting cylinder 24 extends into the interior of the radiator 10, and the fan blade 25 is embedded in the inner side of the protective ring 18. The isolation cover 22 can protect the fan 20, and the protective ring 18 can protect the fan blade 25 to prevent debris from damaging the end of the fan blade 25. The fan blade 25 extends into the interior of the radiator 10 and can directly blow the heat on the heat dissipation aluminum fin 13, accelerate the dissipation of heat on the heat dissipation aluminum fin 13, and improve the heat dissipation effect. In addition, multiple sets of heat dissipation aluminum fins 13 and the fan 20 are directly opposite each other, and the diameter of the fan blade 25 is the same as the height of the heat dissipation aluminum fin 13. In this way, when the fan 20 rotates, the airflow generated can pass through multiple sets of heat dissipation aluminum fins 13 well, accelerating the diffusion of heat.

[0033] Please see Figures 3-5 The cleaner 30 includes slide rails 31 fixed to the left and right side walls inside the heat dissipation window 12. Two sets of slide rails 31 have slide tracks 32. Each slide track 32 has a sliding seat 33 slidably mounted inside it. Cleaning scrapers 34 are fixed to the outer ends of the left and right sets of slide seats 33. The cleaning scrapers 34 are fitted against the outer side walls of the heat dissipation aluminum fins 13. Electromagnetic plates 36 matching the cleaning scrapers 34 are fixed to the top and bottom of the inner cavity of the radiator 10. The cleaning scrapers 34 are arranged in two sets, symmetrically positioned on the upper and lower sides inside the heat dissipation window 12, with each set of cleaning scrapers 34 spanning multiple sets of heat dissipation aluminum fins 13. Each set of electromagnet plates 36 corresponds to each set of cleaning scrapers 34. Each set of cleaning scrapers 34 has a magnetic strip that matches the electromagnet plates 36. The cleaner 30 also includes scraping blocks 37 fixed on the rear side wall of the cleaning scrapers 34. Each set of scraping blocks 37 is embedded in the ventilation channel 17. The scraping blocks 37 are rubber bags. Airbags 35 are fixedly assembled between two sets of slide seats 33 in the same slide rail 32. Each set of airbags 35 is connected to the scraping blocks 37 through an air supply pipe. The size of the scraping blocks 37 matches the ventilation channel 17, and the number of scraping blocks 37 is twice the number of ventilation channels 17.

[0034] In actual use, the cleaner 30 can start working when the fan speed decreases during the operation of the fan 20. Then, the cleaner 30 can be used to clean the deposits on the surface of the heat sink aluminum fin 13, thereby achieving the purpose of unblocking and realizing the self-cleaning of the heat sink 10. That is, after the electromagnet plate 36 is energized, it generates a magnetic repulsion force on the cleaning scraper 34, thereby pushing the cleaning scraper 34 to move on the surface of the heat sink aluminum fin 13. Simultaneously, the slide 33 moves in the slide 32. When the two sets of cleaning scrapers 34 move towards each other, the cleaning scraper 34 scrapes and cleans the heat sink aluminum fin 13, and the air bag 35 between the slides 33 is squeezed synchronously, so that the gas inside the air bag 35 is introduced into the scraper block 37 through the air supply pipe, thereby causing the scraper block 37 to expand. In this way, when the cleaning scraper 34 moves, it can simultaneously drive multiple sets of scraper blocks 37 to move, so as to scrape and clean the debris inside the ventilation channel 17, avoiding the accumulation of impurities inside the ventilation channel 17 and affecting the air circulation.

[0035] When the two sets of cleaning scrapers 34 reach the middle position, the two sets of electromagnet plates 36 input reverse current. At this time, the electromagnet plates 36 generate a magnetic attraction force on the cleaning scrapers 34, thereby driving the two sets of cleaning scrapers 34 to move away from each other. This allows the cleaning scrapers 34 to repeatedly scrape the surface of the heat sink aluminum fin 13. During this process, the fan 20 rotates in the opposite direction, which generates an airflow from back to front. This airflow blows and cleans the accumulated material and dust after scraping, improving the cleanliness of the surface of the heat sink aluminum fin 13. At the same time, during the process of the two sets of cleaning scrapers 34 moving away from each other, the gas inside the scraper block 37 flows back to the air bag 35 through the air pipe. In this way, the dust inside the ventilation channel 17 can be cleaned by the blowing of the fan 20.

[0036] It is worth noting that a wind speed sensor is fixedly installed inside the radiator 10. This sensor can detect the airflow speed from inside the radiator 10, thus enabling real-time monitoring of its operating status. When the ship is in motion, the wind speed through the radiator 10 increases. Therefore, it is necessary to consider both the ship's speed and the wind speed inside the radiator 10 to assess its blockage. When the airflow speed inside the radiator 10 changes, the operating status of the self-cleaning shipboard radiator can be determined. When the wind speed sensor detects a difference between the wind speed at the ship's current speed and the theoretical wind speed within the standard error range, it indicates that the radiator 10 is operating well and ventilation is adequate. The wind speed sensor detects that the difference between the wind speed value at the ship's current speed and the theoretical wind speed value is outside the standard error range. This indicates that the radiator 10 is in a dust accumulation state under the current condition, which seriously affects the ventilation performance of the radiator 10. At this time, the cleaner 30 is controlled to start working, so that the cleaner 30 scrapes and cleans the dust accumulated on the surface of the heat sink aluminum fin 13. At the same time, after the ship stops, the cleaner 30 continues to work while controlling the fan 20 to rotate in the opposite direction. The reverse blowing of the fan 20 is used to clean the dust scraped off the radiator 10, which is convenient for cleaning the sticky substances such as poplar catkins that are difficult to clean, and avoids the situation where the cleaner 30 cannot clean it completely.

[0037] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
