Description
Technical field
The present invention relates to cooling system technical field, more particularly to a kind of shiphoard machinery system with heat exchanger group
Cooling system.
Background technology
Aboard ship, power set provide power to ship, and the time is grown, and power set can generate heat, when temperature is excessive, power
Device can stop operating, and have a kind of shiphoard machinery system cooling system at present, and shortcoming is, when the shiphoard machinery system is applied to water
Matter more turbid water domain when, such as floods spot, the foreign matter in water is easy to that the runner will be inhaled into current
It is interior, cause the runner block, and cause the current effectively the heat exchanger can not be cooled down, in turn result in the power source because
Shut down for overheat, ship is run out of steam, reliability is bad.
The content of the invention
A kind of the defects of the object of the invention is exactly to make up prior art, there is provided power peculiar to vessel with heat exchanger group
The cooling system of device.
The present invention is achieved by the following technical solutions：
A kind of cooling system of the shiphoard machinery system with heat exchanger group, includes shiphoard machinery system, in power peculiar to vessel
The upper end of device is equipped with power source, and heat exchanger one is connected with below the power source, pacifies in other sides of power source
Equipped with heat exchanger group, the heat exchanger group is composed in series by multiple heat exchangers two, in each heat exchanger
Helix tube is equipped with two, the lower end of shiphoard machinery system is equipped with a propeller, and the propeller is connected with power source, in power
The both sides below heat exchanger one that are internally located at of device have into cooling water flow conduits and go out cooling water flow conduits, into cooling water
Runner and go out the lower ends of cooling water flow conduits with being connected on the outside of power set, water pump, water are connected with into the upper end of cooling water flow conduits
The water outlet connection heat exchanger one of pump, goes out the upper end connection heat exchanger one of cooling water flow conduits, into cooling water flow conduits and going out
The lower end of cooling water flow conduits is respectively equipped with funnel-form expansion mouth, strainer is internally provided with funnel-form expansion mouth, in power set
Portion is located at both sides above power source and has a spare cooling duct, the lower end of spare cooling duct respectively with heat exchanger group
Both ends connection, the upper end of spare cooling duct is in communication with the outside, and the upper end of one of them spare cooling duct is connected with cooling
Medium pipeline, cools down the other end connection liquid nitrogen supply equipment of medium pipeline, liquid level is equipped with one inner wall of heat exchanger
Sensor, is aboard ship connected equipped with controller, the liquid level sensor by transmission line with controller, and the controller connects
It is connected to alarm.
After shiphoard machinery system starts, extraneous current will be by entering in heat exchanger, with band into cooling water flow conduits
The heat source on the heat exchanger is walked, and the power source can be cooled down, then is gone out from cooling water flow conduits are gone out, is prevented with reaching
The effect that power source overheat shuts down, strainer can prevent the debris in water from resulting in blockage into air stream enter runner, when in heat exchanger
Water level it is too low when, alarm sends alarm, illustrates that strainer is plugged, and staff switches off the pump, open liquid nitrogen supply equipment,
Cooled down by spare cooling duct to power set, after the debris that staff can be on strainer have been cleared up, closed spare cold
But passage, continues through and is cooled down into cooling water flow conduits, and the present invention is equipped with the heat being composed in series by multiple heat exchangers two
Exchanger group, liquid nitrogen sequentially enter heat exchanger below from first heat exchanger, the low temperature of liquid nitrogen are made full use of, to power
Each orientation in source is cooled down, and helix tube can increase cooling time, good cooling results.
It is an advantage of the invention that：The present invention is equipped with spare cooling duct, when strainer is blocked, in the same of cleaning debris
When, start spare cooling duct, in addition present invention uses heat exchanger group, the low temperature of liquid nitrogen can be made full use of, to power source
Each orientation cooled down, add liquid nitrogen cooling time, and save the use of liquid nitrogen, neither delay the cold of power set
But, but save the energy, economical and practical, good cooling results.
