Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The ship cooling system 1 provided by the present invention is described below with reference to fig. 1 to 3.
Referring to fig. 1, the present invention provides a ship cooling system 1, including: the cooling device 2 comprises a cooler 5 and a heat exchange loop 6, wherein a heat exchange medium flows through the heat exchange loop 6, the heat exchange loop 6 is provided with a heat exchange inlet 12 and a heat exchange outlet 13, and the heat exchange inlet 12 and the heat exchange outlet 13 are respectively communicated with the cooler 5. In this embodiment, the heat exchange medium is fresh water cooling water, which has a large specific heat capacity of water, and can achieve a good heat exchange effect. The ship equipment 3 is disposed on the heat exchange circuit 6, and it should be noted that the ship equipment 3 is generally a plurality of heat generating equipment on the ship, such as an engine, a turbine, and the like. The ship equipment 3 is positioned between the heat exchange inlet 12 and the heat exchange outlet 13, and takes away the residual heat of the equipment through the flow of the heat exchange medium to cool.
And the heat storage heat exchanger 4 is arranged on the heat exchange loop 6, is positioned behind the ship equipment 3 and is close to the heat exchange outlet 13. The marine environment where the ship power device is located is complex and changeable, and the operation conditions of the ship power device are frequently switched, so that the heating load of each ship device 3 fluctuates. Because the heat exchange efficiency of the heat exchange medium is kept stable, when the heat load of part of high-power ship equipment 3 fluctuates or faces instantaneous thermal shock, the temperature of the heat exchange medium at the heat exchange outlet 13 can fluctuate violently and can reach +/-10 ℃ in serious cases. In the process of circulating and flowing of the heat exchange medium, adverse effects can be indirectly caused to other ship equipment 3, and particularly, the working performance of the equipment is affected by overhigh or overlow temperature of some devices and equipment sensitive to cooling temperature. The invention inhibits the temperature fluctuation of the heat exchange medium in the ship cooling system 1 by arranging the heat storage heat exchanger 4 and utilizing the heat storage heat exchanger 4 to store and release heat. The heat storage heat exchanger 4 absorbs and stores redundant heat when the system is in high heat load and discharges the heat when the system is in low heat load, so that the temperature fluctuation of a heat exchange medium is effectively inhibited, and the adverse effect of the high-power fluctuation heat load of the single ship equipment 3 on the cooling device 2 and other low-power ship equipment 3 is eliminated.

The heat storage material 8 is arranged in the heat exchange cavity 16 and used for exchanging heat with a heat exchange medium. The heat storage material 8 can exchange heat with a heat exchange medium, and can absorb redundant heat at the average temperature of the heat exchange medium when the temperature of the heat exchange medium is higher; in the case where the temperature of the heat exchange medium is low, the heat stored in the heat storage material 8 can be taken away by the heat exchange medium. Therefore, no matter how the heating condition of each ship device 3 is, a relatively stable temperature interval can be always ensured by the heat exchange medium, and the efficient and stable operation of the whole ship cooling system 1 is favorably maintained.
In the technical scheme provided by the invention, the heat exchange cavity 16 is provided with the medium flow splitters 19 at positions close to the first heat exchange interface 17 and the second heat exchange interface 18, each medium flow splitter 19 is provided with a plurality of flow splitting channels, and the medium flow splitters 19 are used for splitting the heat exchange medium.

Through setting up medium shunt 19, on the one hand shunts heat transfer medium, reduces the influence of effort to heat accumulation material 8, and on the other hand shunts heat transfer medium for contact is more abundant between heat transfer medium and the heat accumulation material 8, is favorable to improving heat exchange efficiency. Referring to fig. 2, in the present embodiment, the medium splitter 19 is a splitter plate, and a plurality of openings are formed on the splitter plate to form the splitting channels for splitting the heat transfer medium.
The heat storage material 8 may be provided in various forms, for example, a plurality of pipes are provided to fill the heat storage material 8 in a conventional manner, so that the heat exchange medium is sufficiently in contact with the pipes during the flowing process to exchange heat. In order to improve the heat exchange efficiency, in the technical scheme provided by the invention, the heat storage material 8 comprises a plurality of spherical medium bodies 20, each spherical medium body 20 is stacked in the heat exchange cavity 16, and a heat exchange gap is formed between each spherical medium body 20. Due to the arrangement, the heat exchange medium flows in the heat exchange gaps, and can be in full contact with the spherical medium bodies 20, so that the heat exchange efficiency is improved. In addition, the heat storage material 8 may be provided in other shapes, such as a square shape, a triangular shape, and the like, which is not limited by the present invention.
Further, in the present embodiment, the heat storage material 8 is spherical and has a certain fluidity, and may move during the heat exchange process. In order to prevent the spherical medium body 20 from blocking the shunt channel and affecting the flow of the heat exchange medium, a plurality of protrusions 21 are arranged on one side of each medium shunt 19 close to the spherical medium body 20, and the protrusions 21 are used for supporting the spherical medium body 20 so as to enable the spherical medium body 20 to be far away from the shunt channel.
