Bottom of the shell as heat exchange water tank 14 can enable heat exchange water tank 14 have biggish base area and lesser water tank height.
According to the leaving water temperature of the collected water cooling equipment of temperature sensor, the working condition of cooling water system is determined.?
When cooling water system works, temperature sensor 11 persistently detect the leaving water temperature of water cooling equipment 13, and by collected water temperature out
Degree is sent to controller 12.
When deep-sea manned platform is in surface navigation state, external dynamic sea temperature is higher, and temperature sensor 11 acquires water
The leaving water temperature of cool equipment 13, if the collected leaving water temperature of temperature sensor 11 is greater than the first temperature, outboard cooling circuit
In electric check valve 3 close, sea water pump 1 and fresh water pump 10 are opened, and the first hull valve 6 and the second hull valve 7 are opened, the one or three
Aperture between cross valve 8 and the first end a and second end b of the second three-way change-over valve 9 is maximum, 8 He of the first three-way change-over valve
Aperture between the first end a and second end c of second three-way change-over valve 9 is zero.
It is carried out at this point, the fresh water flowed out in water cooling equipment 13 in external dynamic sea and cabin is sent into Intermediate Heat Exchanger 2 out of my cabin
Heat exchange returns to ocean after seawater heat absorption, in the water cooling equipment 13 in fresh water return capsule, recycles repeatedly.
When deep-sea manned platform dive, external dynamic sea temperature starts to be gradually reduced, the leaving water temperature of water cooling equipment 13
Begin to decline therewith, when the collected leaving water temperature of temperature sensor 11 be equal to the first temperature, and be equal to the first temperature water outlet
Temperature is when occurring for the first time, and controller 12 controls the first three-way change-over valve 8 and the driving motor of the second three-way change-over valve 9 turns
It is dynamic, reduce the aperture of the first end a to second end b of the first three-way change-over valve 8 and the second three-way change-over valve 9, first end a to the
The aperture of three end c increases so that the fresh water that water cooling equipment 13 flows out starts to shunt at the first three-way change-over valve 8, a part after
Continue original side of a ship outer circulation, another part enters heat exchange water tank 5, and the fresh water that heat exchange water tank 5 flows out is at the second three-way change-over valve 9
Collect with the fresh water that outboard flows back to, return again in water cooling equipment 13, realizes circulation.Due to the fresh water and outboard in heat exchange water tank 5
There are the temperature difference between seawater, therefore the fresh water in the water tank 5 that exchanges heat can be passed by the bilge for the water tank 5 that exchanges heat towards external dynamic sea
Heat, but since the heat-transfer capability of the bottom surface of heat exchange water tank 5 is less than Intermediate Heat Exchanger 2, the fresh water temperature that water cooling equipment 13 flows out
Degree will gradually go up, until the fresh water temperature that water cooling equipment 13 flows out is restored to second temperature, the first three-way change-over valve 8 and second
The driving motor stopping of three-way change-over valve 9 acts；It should be noted that the mistake of the fresh water temperature recovery flowed out in water cooling equipment 13
Cheng Zhong, the first three-way change-over valve 8 and the second three-way change-over valve 9 still under the action of driving motor, increase first end a and third end
Aperture between c reduces the aperture between first end a and second end b.
With the promotion of deep-sea manned platform submerged depth, ocean temperature continues to decline, and the above process would be repeated for, directly
The aperture for being switched completely to first end a to third end c to the first three-way change-over valve 8 and the second three-way change-over valve 9 is maximum, first end
When the aperture of a to second end b are zero, the driving motor stopping of the first three-way change-over valve 8 and the second three-way change-over valve 9 is acted, together
When, the first hull valve 6 and the second hull valve 7 are closed, and electric check valve 3 is opened.At this point, the piston in pressure equaliser 4 exists
It is slided under seawater pressure from seawater chamber to fresh water chamber, makes the pressure balance of fresh water chamber and seawater chamber, the heat exchanger tube of Intermediate Heat Exchanger 2
And the overpressure of outboard fresh water line is equal with external dynamic sea, the heat exchanger tube and outboard fresh water line of Intermediate Heat Exchanger are not held
By inside and outside differential pressure.
Optionally, the first temperature and second temperature determines according to actual conditions, and the first temperature be lower than second temperature.
It should be noted that when deep-sea manned platform floats, according to the collected water cooling equipment 13 of temperature sensor 11
Leaving water temperature, the inverse process when course of work of the cooling water system of deep-sea manned platform is dive, i.e., in floating-upward process,
With the raising of ocean temperature, the aperture between the first three-way change-over valve and the first end and second end of the second three-way change-over valve increases
Adding, the aperture between first end and third end reduces, until the aperture between first end and second end is maximum, first end and third
Aperture between end is zero, and those skilled in the art can not pay creatively to work and be directly determined according to above content, this hair
It is bright to repeat no more.
It should be noted that：The serial number of the above embodiments of the invention is only for description, does not represent the advantages or disadvantages of the embodiments.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
