Abstract
The invention discloses a ship cooling system, which comprises a high-temperature fresh water system, a low-temperature fresh water system and a heat exchanger, wherein the high-temperature fresh water system comprises a host, a high-temperature fresh water circulating pump, a high-temperature fresh water pipe and the heat exchanger; the low-temperature fresh water system comprises a low-temperature fresh water circulating pump, a low-temperature fresh water pipe, a heat exchanger and an indirect evaporative cooler; the high-temperature fresh water system is connected with the low-temperature fresh water system through a heat exchanger. The invention uses the indirect evaporation cooler to replace the seawater cooling system in the prior art, and the corrosion problem of seawater does not exist; the system is simple, the workload of crew is reduced, and the daily maintenance cost is reduced for a ship company; a high-power seawater pump is omitted, so that the ship construction expense and the daily operation cost can be reduced to a great extent; the influence of the sea water temperature on the cooling effect due to ship route and seasonal variation can be solved.
Description
Technical field
The present invention relates to a kind of cooling system, particularly a kind of boats and ships cooling system.
Background technology
Boats and ships are in the navigation way, and the caloric requirement cooling water expansion tank that marine main engine produced carries out circulation cooling, and then make main frame cylinder sleeve temperature remain in the best scope.At present, the boats and ships cooling system extensively adopts central cooling system, and is as shown in Figure 1, and this system comprises: high temperature fresh water system, low temperature fresh water system and salt water cooling system.The high temperature fresh water system comprises main frame 1, high temperature fresh water circulating pump 4, high temperature fresh water pipe and heat exchanger 2; The low temperature fresh water system comprises low temperature fresh water circulating pump 5, low temperature fresh water pipe, heat exchanger 2 and plate type heat exchanger 3; Salt water cooling system comprises high-order sea chest 8, low level sea chest 9, sea water pump A6, sea water pump B7, plate type heat exchanger 3 and seawater discharge orifice 10.High-order sea chest 8 is located at respectively by two side boards of boats and ships with low level sea chest 9.After the ship entry,, use high-order sea chest 8 because underwater silt dirt is more more.And when riding the sea,, use low level sea chest 9 for preventing to cause suction because of stormy waves more.When boats and ships when harbour is stopped, general withdraw from use is near the sea chest of harbour one side, and uses outside sea chest instead, stops up to prevent dirt.Owing to when boats and ships lean on departure from port mouthful, need often to switch high-order sea chest 8 and low level sea chest 9, clean seawater filter, so make crewman's task increase the weight of.
In addition, in the process of utilizing cooled with seawater low temperature fresh water, also can cause following problem: (1) seawater causes the service life of pipeline very short to the corrosion of seawaterline, in addition can cause sewing, problem such as pollution.(2) seawater can bring problems such as maintenance, repairing to corrosion of pipe, not only increases crewman's task, and expensive maintenance charge can cause damage to shipping company.(3) for whole saltwater system; The cost of the pipeline of its saltwater system, valve member and 2 Taiwan Straits water pumps 6,7 is about 250,000 yuan; In addition the power of sea water pump 6,7 all bigger (30 ~ 40kW), therefore also can increase the boats and ships consumption of current, shipping company's spending is increased.(4) when boats and ships under the line near or when navigating by water summer because sea temperature is higher, makes and the heat exchange deleterious of plate type heat exchanger 3 possibly cause pyrolytic damage the cylinder sleeve and the cylinder head of main frame 1, also can cause other device fails of boats and ships indirectly.
Summary of the invention
Be to solve the problems referred to above that prior art exists, the present invention will design and a kind ofly avoid marine corrosion, can reduce crewman's work capacity, can reduce the boats and ships cooling system of manufacturing cost and maintenance cost.
To achieve these goals, technical scheme of the present invention is following: a kind of boats and ships cooling system, comprise high temperature fresh water system, low temperature fresh water system and heat exchanger, and described high temperature fresh water system comprises main frame, high temperature fresh water circulating pump, high temperature fresh water pipe and heat exchanger; One end of described main frame is connected with heat exchanger with the high temperature fresh water circulating pump through the high temperature fresh water pipe successively, and is connected to the other end of main frame at last; Described low temperature fresh water system comprises low temperature fresh water circulating pump, low temperature fresh water pipe, heat exchanger and indirect evaporation cooler; One end of described indirect evaporation cooler is connected with heat exchanger with the low temperature fresh water circulating pump through the low temperature fresh water pipe successively, and is connected to the other end of indirect evaporation cooler at last; Said high temperature fresh water system links to each other through heat exchanger with the low temperature fresh water system.
Compared with prior art, the present invention has following beneficial effect:
1, the present invention utilizes indirect evaporation cooler to replace salt water cooling system of the prior art, does not have the etching problem of seawater.
2, the present invention utilizes indirect evaporation cooler to replace salt water cooling system, makes system simple, has both reduced crewman's work capacity, has reduced the daily attention expense for shipping company simultaneously.
3, the present invention utilizes indirect evaporation cooler to replace salt water cooling system, has saved high-power sea water pump, can reduce ship building spending and daily running cost significantly.
4, the present invention utilizes indirect evaporation cooler to replace salt water cooling system, can solve sea temperature since steamer line and seasonal variation to the influence of cooling performance.
