Problems solved by technology
However, this cooling system has the inherent disadvantage of being generally arranged inside the hull, which does not fundamentally solve the problem of its large size and occupying a lot of space
When the requirements of the ship power plant increase the output power by increasing the design parameters, the corresponding cooling system will inevitably increase accordingly to increase the heat exchange area to meet the cooling requirements of the power plant, resulting in an excessively large volume occupied by the cooling system. The first contradiction is more prominent, and the cooling rate of the existing cooling system is fixed, when the heat exchange device is required

Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the drawings and embodiments.
[0026] See figure 1 with 2 As shown, the embodiment of the present invention provides a heat exchange system for a ship's power plant. The ship includes a hull 1 and a propulsion device 2. The hull 1 is provided with a stern 3 close to the propulsion device 2, and the heat exchange system includes a stern fixed on the ship. 3, the cooling channel 4, the partition 6, the heat exchange device 5 and the flow regulating device 8. The cooling channel 4 is provided with a cooling water inlet 41 and a cooling water outlet 42 at both ends. The cooling water inlet 41 is located at the stern 3 away from the propulsion device At one end of 2, the cooling water outlet 42 is close to the propulsion device 2, and the cooling channel 4 is provided with a cooling channel 4 for cooling water to pass through. Preferably, the partition 6 is cylindrical, and the partition 6 is pr...

The invention discloses a heat exchange system for a ship power device and a ship provided with the heat exchange system and relates to the field of ship heat exchange. The ship includes a ship body and a propelling device, and a stern close to the propelling device is arranged on the ship body. The heat exchange system comprises a cooling channel for cooling water to pass through, a cylindrical partition piece arranged in the cooling channel and a heat exchange device arranged in an inner flow channel, wherein the cooling channel is fixed to the outside of the stern, the partition piece divides the cooling channel into the inner flow channel and an outer flow channel, and the heat exchange device is connected with the power device. According to the heat exchange system, the space occupiedby the cooling system in the ship body can be reduced.
Description
Technical field [0001] The invention relates to the field of heat exchange of ships, in particular to a heat exchange system used for a ship's power plant and a ship provided with the heat exchange system. Background technique [0002] The propulsion power plant of large ships often needs to use large heat exchange devices, piping systems and accessories to form a cooling system to maintain the continuous and stable thermal cycle. Such as figure 1 As shown, these cooling systems occupy a large amount of space in the hull, which reduces the power-volume ratio parameters of the ship and lowers the technical and economic efficiency. At the same time, it increases the difficulty of installation, repair and maintenance of the power system, and squeezes the space for personnel activities. The livability of ships deteriorates. [0003] Various researches have been carried out on the integration and compact design of the ship’s cooling system, resulting in a significant reduction in the o...
