Description

Technical Field

[0001] The utility model belongs to the technical field of ship engines, and specifically relates to a main engine cooling system for a dual-fuel engine ship. Background Art

[0002] When the main engine of a ship's dual-fuel engine is working, a large amount of heat energy will be generated, and a cooling system is required to take away this heat in time. Cooling the main engine of a ship's engine is not only to cool the cylinder block of the combustion chamber, but also to cool all the heat-receiving components of the entire main engine of the engine. These heat-receiving components include, but are not limited to, the cylinder block, cylinder head, piston, valve, fuel injector, etc. of the combustion chamber. They will be directly affected by high-temperature gas during the working process, and the temperature will rise sharply. The main function of the cooling system is to prevent a series of problems caused by these heat-receiving components due to excessive temperature, such as the decline of the mechanical properties of materials, the generation of thermal stress and deformation, excessive wear and even damage, etc. At the same time, the cooling system can also keep the intake air temperature and lubricating oil temperature within an appropriate range to ensure the normal operation and power output of the engine.

[0003] However, the cooling fan of the existing main engine cooling system for dual-fuel engine ships is usually arranged at the end of the main engine. This layout limits the direct adsorption ability of the fan to the heat inside the main engine. The blowing range of the fan is limited, and it is difficult to fully cover all heat sources inside the main engine. The structure of the ship's main engine is complex, with many components, and there are many gaps and dead corners that are difficult to reach. Traditional heat dissipation components often cannot penetrate into these areas, resulting in heat accumulation in these parts, affecting the overall heat dissipation effect, and the accumulated heat may accelerate the aging and damage of components; and even if the existing main engine cooling system uses a water-cooling component for cooling, the heat transfer efficiency and heat transfer effect of the conventional water-cooling component are not ideal enough, and it is difficult to quickly absorb the large amount of heat energy generated when the main engine of the ship's dual-fuel engine is working.

[0004] Therefore, we provide a main engine cooling system for a dual-fuel engine ship to solve the above problems. Content of the Utility Model

[0031] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0032] Embodiment 1

[0033] In order to solve the problem that the cooling fan of the main engine cooling system for dual-fuel engine ships is usually arranged at the end of the main engine, the blowing range of the cooling fan is limited, it is difficult to fully cover all heat sources inside the main engine, it is difficult to completely absorb the heat generated by the main engine only relying on the cooling fan, and the traditional heat dissipation components are often difficult to penetrate into the gaps and dead corners of the various components of the ship's main engine, resulting in heat accumulation in these parts and affecting the overall heat dissipation effect. Please refer to Figure 1 , the main engine cooling system for dual-fuel engine ships provided by the present utility model includes a cooling fan 1 located at the end of the engine main engine and a carrying frame 2 located on both sides of the engine main engine. A plurality of vertically adjustable iron plate bodies 201 are arranged in the carrying frame 2, and a water cooling component 3 extending into the gaps between the components of the engine main engine is adsorbed on the iron plate body 201. A cold water equipment 5 for supplying cooling water to the water cooling component 3 is arranged at the bottom of the cooling fan 1. The engine main engine can be air-cooled by the cooling fan 1 and water-cooled by the water cooling component 3. The two heat dissipation methods are combined to greatly improve the overall heat dissipation effect, and the water cooling component 3 can extend into the gaps between the components of the engine main engine to avoid heat accumulation in the gaps and dead corners of the various components of the ship's engine main engine.

[0034] As shown in Figure 3As shown in the figure, the water-cooling component 3 includes a magnet seat 301 magnetically fixed on the iron plate body 201 and an adjusting screw 302 movably penetrating through the magnet seat 301; a rotating seat 303 is fixedly arranged at the end of the adjusting screw 302, a threaded shaft 304 is rotatably arranged on the rotating seat 303, a nut 305 for locking the threaded shaft 304 is sleeved on the threaded shaft 304, an installation frame 306 is fixedly arranged at the end of the threaded shaft 304, a water-cooling pipe 307 is fixedly arranged on the installation frame 306, fins 308 are arranged on the surface of the water-cooling pipe 307, and the fins 308 can effectively increase the heat-absorbing area of the water-cooling pipe 307, so that heat energy can be more fully transferred to the cooling water in the water-cooling pipe 307, improving the efficiency of heat energy transfer and the cooling effect of the system. When it is necessary to extend the water-cooling component 3 into the gaps and dead corners of each component of the ship engine main engine, loosen the nut 305. At this time, the threaded shaft 304 can rotate freely on the rotating seat 303. Based on the gap angle of the engine main engine, rotate the installation frame 306 to an angle matching the gap, then hold the installation frame 306 by hand, and then manually rotate the adjusting screw 302. The adjusting screw 302 drives the rotating seat 303 to rotate and approach the engine main engine. The rotating seat 303 drives the threaded shaft 304, the installation frame 306 and the water-cooling pipe 307 to move until the water-cooling pipe 307 extends into the gap of the engine main engine, and finally tighten the nut 305; the angle and the extending length of the water-cooling component 3 itself can be adjusted, so as to adapt to the use requirements of different specifications of engine main engines. The water-cooling component 3 can be adjusted to the best position for absorbing heat energy, improving the heat exchange effect.

[0035] As Figure 3 , Figure 7 shown in the figure, flexible water inlet connecting pipes 309 and water outlet connecting pipes 310 are respectively arranged at both ends of the water-cooling pipe 307; a water inlet common rail pipe 501 communicated with the water inlet connecting pipe 309 and a water outlet common rail pipe 502 communicated with the water outlet connecting pipe 310 are respectively arranged on the cold water device 5. The water inlet common rail pipe 501 and the water outlet common rail pipe 502 are horizontally fixed on the bearing frame 2 through pipe clamps. The water inlet connecting pipes 309 of a row of water-cooling components 3 are all communicated with the same water inlet common rail pipe 501, and the water outlet connecting pipes 310 of a row of water-cooling components 3 are all communicated with the same water outlet common rail pipe 502. During use, the cooling water in the cold water device 5 flows into each water inlet connecting pipe 309 through the water inlet common rail pipe 501, is conveyed to the water-cooling pipe 307 through the water inlet connecting pipe 309. After the water-cooling pipe 307 exchanges heat with the heat generated by the engine main engine, the hot water flows back into the water outlet common rail pipe 502 through the water outlet connecting pipe 310 and flows back into the cold water device 5 through the water outlet common rail pipe 502.

[0036] In order to protect the water-cooling component 3 and improve the integrity and aesthetics of the entire cooling system, as Figure 8As shown, it also includes a protective cover 6 hinged on the side of the bearing frame 2 away from the engine mainframe, and a sound insulation layer 601 is provided on the inner surface of the protective cover 6. The protective cover 6 can not only protect the water cooling component 3, but also play a certain protective role. When the engine mainframe is at risk, it can protect the surrounding people from being hurt. At the same time, it also plays a certain noise reduction role, effectively isolating the vibration sound emitted by the engine mainframe, the water cooling component 3 and the ultrasonic component 4.

[0037] Embodiment 2

[0038] On the basis of the first embodiment, in order to further solve the problem of adaptability of the water cooling assembly 3, as shown in FIG. Figure 2 As shown, the iron plate body 201 is slidably arranged in the bearing frame 2 and locked by a fastener, and a slide groove 202 that is slidably matched with the iron plate body 201 is provided in the bearing frame 2, and a first slot hole 203 for the fastener to pass through is provided on the upper side of the bearing frame 2. Based on the actual condition of the dual-fuel engine main engine of the ship, the position of the iron plate body 201 in the bearing frame 2 is adjusted, and then the position of the water cooling component 3 in the bearing frame 2 is adjusted to adapt to the use requirements of different engine main engines; when adjusting, loosen the fastener at the upper end of the iron plate body 201, at this time, the iron plate body 201 can move freely along the slide groove 202, and the fastener can move freely along the first slot hole 203. After reaching the desired position, tighten the fastener, and the position of the magnet seat 301 can be fine-tuned through the adsorption effect of the iron plate body 201 and the magnet seat 301, so that the water cooling component 3 can be adjusted to the best position suitable for the engine main engine.

[0039] One end of the carrier frame 2 is hinged to the cooling fan 1, and a support 101 for hinge connection is provided on the cooling fan 1, and a fastener for locking the carrier frame 2 is provided on the top of the support 101. The carrier frame 2 can be opened and closed, which is convenient for installation and maintenance of the water cooling component 3 thereon, and the angle between the carrier frame 2 and the cooling fan 1 can also be freely adjusted to meet the use requirements of different engine hosts.

[0040] Embodiment 3

[0041] On the basis of the first and second embodiments, in order to further improve the heat transfer effect of the water cooling component 3, as shown in FIG. Figure 1 , Figure 5As shown, it also includes an ultrasonic component 4 installed on the bearing frame 2 and used to drive multiple water cooling components 3 to vibrate at the same time; the ultrasonic component 4 includes an ultrasonic generator 401 fixed on the side of the bearing frame 2 away from the engine main engine, and a mounting ring 402 is fixedly sleeved on the ultrasonic generator 401, and multiple transmission rods 403 are installed around the mounting ring 402 to abut against the water cooling component 3. The ultrasonic generator 401 drives the mounting ring 402 to vibrate at high frequency, and the mounting ring 402 drives multiple transmission rods 403 to vibrate at high frequency, and the multiple transmission rods 403 drive their respective water cooling components 3 to vibrate at high frequency. The ultrasonic vibration can disturb the cooling water in the water cooling pipe 307, increase the fluidity and mixing of the cooling water, reduce the laminar effect of the cooling water, increase the turbulence of the cooling water, and help the cooling water to better contact with the pipe wall, thereby improving the heat transfer efficiency. The vibration can also promote the movement of tiny bubbles or particles in the cooling water, reduce their hindering effect on heat transfer, and enhance the cooling effect. It is worth mentioning that the position of the ultrasonic component 4 on the bearing frame 2 can be adjusted based on actual conditions to adapt to the use requirements of different engine main engines.

[0042] An annular groove 402a is provided on the surface of the mounting ring 402, and a sliding seat 403a sliding in the annular groove 402a is provided at the end of the transmission rod 403; a fastener for locking the sliding seat 403a and a second slot 402b for the fastener to pass through are provided on the side of the mounting ring 402; one end of the transmission rod 403 is rotatably arranged in the sliding seat 403a through a rotating shaft, and a torsion spring is sleeved on the rotating shaft, and the other end of the transmission rod 403 abuts against the adjusting screw 302. The position of the transmission rod 403 on the mounting ring 402 can be freely adjusted, so as to meet the use requirements of the water cooling assembly 3 at different positions. When adjusting, loosen the fastener on the side of the mounting ring 402, at this time, the sliding seat 403a can move freely along the annular groove 402a, and the fastener can move freely along the second slot 402b. After reaching the desired position, tighten the fastener, and under the action of the torsion spring, the transmission rod 403 can abut tightly against the adjusting screw 302.

[0043] In order to use the ultrasonic component 4 to simultaneously drive multiple water cooling components 3 to vibrate, it is necessary to avoid collision of the transmission rods 403 in the same direction. Figure 6 As shown, a plurality of mounting rings 402 distributed at equal intervals are fixedly mounted on the ultrasonic generator 401 .

[0044] In order to improve the vibration effect of the water cooling assembly 3 itself, Figure 4As shown in the figure, the magnet base 301 includes an outer magnet frame 301a and an inner block 301b located at the center of the outer magnet frame 301a; a plurality of evenly distributed springs 301c are provided between the inner block 301b and the outer magnet frame 301a, and the adjusting screw 302 is penetrated and arranged on the inner block 301b. The transmission rod 403 drives the adjusting screw 302 to vibrate at a high frequency. Due to the arrangement of the plurality of springs 301c, the adjusting screw 302 can drive the inner block 301b to vibrate at a high frequency.

[0045] The above embodiments only represent one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as a limitation to the patent scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
