Description

Technical Field

[0001] This utility model relates to the field of dredging vessels, specifically a heat dissipation device for the pump nacelle of a dredging vessel. Background Technology

[0002] A dredger belongs to the category of dredgers, but it does not have the ability to excavate underwater soil layers. It only has the function of sucking in and blowing out dredged mud. It is a simple blowing vessel, so it belongs to the suction and lifting dredger type. A dredger is a mechanical non-self-propelled dredger and is one of the supporting vessels in dredging, filling and mud transportation to shore construction operations.

[0003] When a dredging vessel is carrying out dredging operations, the equipment in the pump room operates under high load for a long time, generating a lot of heat. If this heat cannot be dissipated in time, it will cause the temperature inside the pump room to be too high, affecting the normal operation of the equipment, and may even cause equipment failure, reduce the service life of the equipment, increase maintenance costs and safety hazards. Most of the existing ship engine room heat dissipation devices have relatively simple structures and limited heat dissipation effects, which are difficult to meet the heat dissipation needs of the pump room of a dredging vessel in such a special environment.

[0023] A heat dissipation device for a dredging vessel pump nacelle includes a housing 8, a heat dissipation mechanism 1 on the left side of the housing 8, an exhaust mechanism 2 connected to the upper surface of the heat dissipation mechanism 1, an air inlet mechanism 3 above the exhaust mechanism 2, a conveying mechanism 4 connected to the upper surface of the housing 8, a connecting pipe 9 connected to the outer surface of the housing 8, a cooler 6 embedded in the outer surface of the housing 8, and a water injection pipe 5 connected to the upper surface of the housing 8.

[0024] In this embodiment, the heat dissipation mechanism 1 includes a housing 101. A support mesh 105 is connected to the inner wall of the housing 101. A heat dissipation coil 106 is connected to the upper surface of the support mesh 105. A set of heat dissipation fins 104 are connected to the outer surface of the heat dissipation coil 106. Both ends of the heat dissipation coil 106 penetrate the housing 101 and extend to the right side of the housing 101. The design of the heat dissipation fins 104 facilitates the absorption of a large amount of heat. The design of the heat dissipation coil 106 facilitates the cooling of the heat dissipation fins 104. A temperature sensor 102 is embedded on the left side of the housing 101. A temperature display 103 is connected to the left side of the housing 101. The cooperation of the temperature sensor 102 and the temperature display 103 facilitates the understanding of the temperature inside the pump chamber.

[0025] In this embodiment, the exhaust mechanism 2 includes a first fan 201 connected to the housing 101. The input end of the first fan 201 is connected to the upper surface of the housing 101, and the output end of the first fan 201 is connected to a metal pipe 202. The cooperation of the first fan 201 and the metal pipe 202 facilitates the exhaust of heat from the heat sink 104 and the pump chamber. The air intake mechanism 3 includes an exhaust hood 301. A second fan 302 is embedded on the right side of the exhaust hood 301, and a pipe 303 is connected to the right side of the second fan 302. The design of the second fan 302, the exhaust hood 301, and the pipe 303 facilitates the exhaust of external cold air into the pump chamber, while improving the heat dissipation effect and being beneficial for current use.

[0026] In this embodiment, one end of the pipe 303 is connected to an air inlet hood 304, and the inner wall of the air inlet hood 304 is connected to a filter screen 305. The cooperation of the air inlet hood 304 and the filter screen 305 facilitates the filtration of dust in the air. The conveying mechanism 4 includes a pump body 401 connected to the housing 8. The input end of the pump body 401 is connected to a cold water suction pipe 402. One end of the cold water suction pipe 402 passes through the housing 8 and extends into the interior of the housing 8. The cooperation of the pump body 401, the cold water suction pipe 402 and the external pipe facilitates the discharge of cold water into the heat dissipation coil 106.

Subsequently, the cooler 6 is used to cool the water inside the box 8, and the pump body 401 and the cold water suction pipe 402 are used to draw in cold water. Then, the cold water is discharged into the heat dissipation coil 106. Subsequently, through the connection between the heat dissipation coil 106 and the connecting pipe 9, the water is discharged into the box 8 to achieve circulating cooling.

[0028] Then, by utilizing the design of the first fan 201 and the casing 101, heat can be absorbed, and a large amount of heat can be absorbed by the heat sink 104. At the same time, through the cooperation of the first fan 201 and the metal pipe 202, the heat is discharged to the outside and the heat sink 104 is cooled. At this time, the cold air emitted by the heat dissipation coil 106 can also cool the heat sink 104.

[0029] Then, by utilizing the design of the second fan 302 and the duct 303, cold air is drawn in when the duct 303 extends outside the ship, and dust in the air is filtered by the cooperation of the air inlet hood 304 and the filter screen 305. At the same time, the air outlet hood 301 discharges the cold air into the pump room, thereby achieving efficient heat dissipation of the pump room.

Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
