Technical Field

[0001] The utility model relates to a cooling device, in particular to a shell-type cooling device for a ship engine, belonging to the technical field of ship engines. Background Art

[0002] Ship engine is a general term for all machinery, equipment and systems installed to meet the needs of ship navigation, various operations, crew life, and the safety of personnel and property. Among them, the ship's power system is the main driving device of the ship during navigation. Most existing ship main engine power units use internal combustion engines such as diesel engines, which generate a lot of heat during the driving process. In order to prevent this heat from being wasted and to prevent heat from scattering into the cabin and causing the cabin temperature to be too high, this heat is mostly used for marine boilers or lubricating oil heating.

[0003] However, the existing cooling shell is completely wrapped around the outside of the exhaust pipe, which can reduce heat loss and avoid heat waste. However, the shell is completely wrapped around the outside of the exhaust pipe, which is more troublesome to install. When the parts are damaged, it is difficult to disassemble and repair the parts inside. For this reason, we provide a shell-type cooling device for ship engines to solve the above problems.

Rotate the side cover 16, align the through hole 17 on the outer surface of the side cover 16 with the through hole 2 18 on the outer surface of the shell 2, and then screw the positioning rod 19 into the through hole 17 and the through hole 2 18, and the two side covers 16 can be installed.

[0024] A pull rod 3 slides through the outer surface of the shell 2, and one end of the pull rod 3 is connected to a fixing clip 4. There are four fixing clips 4 in total, two in a group, and symmetrically distributed at both ends of the shell 2. The shape of the fixing clip 4 is arc-shaped, which can fit well with the outer surface of the smoke pipe 1 to fix the smoke pipe 1. The outer surface of the fixing clip 4 is in contact with the outer surface of the smoke pipe 1. The other end of the pull rod 3 is connected to a rectangular plate 5. The outer surface of the fixing clip 4 is connected to a spring 6. Four springs 6 are provided on the outer surface of one fixing clip 4, which are distributed at the four corners of the fixing clip 4.

[0025] according to Figure 1 、 Figure 2As shown, one end of the spring 6 is connected to the inner wall of the shell 2, and the outer surface of the shell 2 is connected to a telescopic rod 7, one end of the telescopic rod 7 is connected to the outer surface of the rectangular plate 5, and the outer surface of one rectangular plate 5 is connected to two telescopic rods 7, which are symmetrically distributed on the outer surface of the rectangular plate 5.

[0026] One end of the water pipe 8 is fixedly connected to a water outlet pipe 12, and a valve 13 is connected to the outer surface of the water outlet pipe 12. Cold water becomes hot water and flows out of the water outlet pipe 12. The valve 13 can control the flow rate of hot water to achieve the purpose of saving water. The water pipe 8 surrounds the outside of the chimney 1. The water pipe 8 is spirally curved, which can increase the time that cold water stays in the water pipe 8, making it convenient to heat the cold water.

[0028] The utility model is in use: when installing the device, first put a side cover 16 on the outer surface of the smoke pipe 1, then install the shell 2, start the telescopic rod 7, the telescopic rod 7 drives the two fixing clips 4 to move away from each other, and the spring 6 is compressed. When the distance between the two fixing clips 4 is greater than the diameter of the smoke pipe 1, put the shell 2 on the outer surface of the smoke pipe 1, and put the telescopic rod 7 in a relaxed state. The spring 6 will automatically extend and drive the fixing clip 4 to clamp the smoke pipe 1, and the installation of the shell 2 can be completed.

When using the device, there is high-temperature flue gas in the chimney 1, and the heat-absorbing plate 10 will absorb the heat in the high-temperature flue gas and transfer it to the heat sink 11 through the conduction rod 9. The heat in the heat sink 11 is released and released into the interlayer between the chimney 1 and the shell 2. There is a water pipe 8 in the interlayer between the chimney 1 and the shell 2. The heat released by the heat sink 11 increases the temperature in the interlayer between the chimney 1 and the shell 2, and heats the cold water flowing in the water pipe 8. The heated water will be discharged at one end of the water outlet pipe 12, and the high-temperature flue gas will become low-temperature flue gas and be discharged from one end of the chimney 1.
