Shape plate, and the incoming flow section in the front of propeller is arranged in annular slab, and coldplate, each cooling are evenly arranged on the annular slab
The entrance of plate is connected with coolant inlet pipe, and the outlet of each coldplate is connected with coolant outlet, on coolant outlet
The end for being provided with outlet temp.-control valve and coolant outlet is connect with heat sink inlet, and coolant inlet pipe passes through hollow
Conduit after be sequentially connected imported valve, coolant pump, coolant storage tank, radiator outlet.
The invention also includes structure features some in this way:
1. there are four the coldplates.
2. coldplate is hollow prism structure, cross sectional shape is diamond shape.
Compared with prior art, the beneficial effects of the present invention are: it is a kind of improvement to traditional propeller conduit, in spiral shell
The conduit of rotation paddle incoming flow section part arranges circumferentially equally distributed diamond shape coldplate, can be before water flow contacts propeller
Cool down to water；Temp.-control valve is set in coolant circuit simultaneously, when the coolant temperature of reflux is lower than set temperature, is returned
The valve on road can close.The coolant pump of cooling liquid inlet pipe leading portion setting can be by the cooling in coolant storage tank by radiating
In liquid inspiration coldplate, the coldplate full of coolant liquid cools down the fluid of propeller direction of flow back segment, reduces
The generation of vacuole.This cooling conduit has the characteristics that structure is simple, it is good to reduce propeller cavitation effect, will be on naval vessel promotes
With good actual application prospect.

Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing.
In conjunction with Fig. 1 to Fig. 4, cooling conduit of the invention is filled by conduit 19, coldplate 7, valve 12, coolant pump 2, heat dissipation
It sets, the composition of coolant storage tank 1, conduit is arranged in propeller front end, and conduit is by conduit outer wall 11 and 10 groups of pipe inner wall
At hollow structure, propeller includes hub cap 13, propeller blade 14, propeller paddle shaft 15, and four coldplates are along conduit circumferential direction
It is uniformly distributed, two valves are arranged in the inlet and outlet of coolant liquid, and coolant pump is arranged in the inlet pipeline of coolant liquid, and cold
But liquid storage bin is connected, and storage bin is connected with radiator again.Conduit leading portion, that is, propeller incoming flow section arranges circumferentially uniformly
4 coldplates of distribution reduce the fluid temperature (F.T.) of propeller incoming flow section by it to the cooling effect of incoming flow fluid, reduce spiral shell
The vacuole quantity generated in the rotation paddle course of work.Coolant liquid in the coldplate of such cooling conduit is drawn onto cold by coolant pump 2
But the coolant liquid service pipe 18 of plate 7；The opening and closing of the temp.-control valve 6 of coolant circuit section is by flowing into the temperature of the fluid of radiator
It determines；The transmission of the responsible coolant liquid of pipeline 3,4,9；Coldplate 7 is responsible for completing to cool down the incoming flow fluid in conduit.It is cooling
Plate is hollow prism, and coolant liquid passes therethrough.
Cooling device is made of coldplate 7, coolant storage tank 1, radiator 5.Coldplate is by connecting rod 16 and admittedly
Fixed end 17 is fixed on conduit inner ring, disposes a valve respectively on the inlet pipeline 9 and outlet conduit 4 of coldplate, controls cold
But the disengaging of liquid cooling fluid, coolant liquid are entered by storage bin by inlet pipeline by the work of the coolant pump on inlet pipeline
Coolant liquid service aisle 18 flows into radiator 5 by coolant outlet, cools down to the coolant liquid after work, after cooling
Coolant liquid turn again to storage bin, coolant liquid service aisle is then recycled into, by the effect of coldplate in conduit
Incoming flow cools down, and makes to flow intracorporal air bubble content reduction, and then reduce Cavitation effect.The coldplate of cooling conduit of the invention
Inlet and outlet control valve and coolant pump be placed on the outside of conduit, can achieve the function of control by opening and closing on the outside
Energy.Coldplate section uses diamond shape, and inner passage is also diamond shape, and coolant liquid is drawn by the effect of coolant pump from storage bin
The service aisle of coolant liquid generates heat exchange by coldplate and incoming flow fluid.When closing the cooling function of propeller nozzle,
The valve or coolant pump of inlet and outlet can be closed.Wherein the valve at coolant outlet is temp.-control valve, when in circuit
Coolant liquid when being lower than set temperature, valve herein can be automatically closed, so that the fluid lower than set temperature be made to work on,
Without being into radiator, portion of energy has been saved.
The control principle of cooling conduit of the invention are as follows:
(1) dynamical system of hull interior coolant liquid by coolant pump 2 that 1 temperature in coolant storage tank is sufficiently low
It is drawn into the coolant liquid service aisle 18 of coldplate 7 by cooling liquid inlet pipe 9, completes heat exchange later from cold with incoming flow fluid
But liquid outlet 4 flows out, and enters radiator 5, then turns again to storage bin from the outflow of radiator outlet pipe 3, completes primary
Cooling cycle；
(2) internal circumferential of the cooling conduit is evenly distributed with four pieces of coldplates altogether, is connected, is passed through by annular slab 8
Connecting rod 16 and fixing end 17 between connecting plate and conduit 19 realize fixation of the coldplate in conduit；
(3) according to the needs of different operating conditions, to change the opening and closing situation of inlet and outlet, this process be by coolant pump,
Cooling liquid inlet pipeline valve 12 and cooling liquid outlet pipeline valve 6 complete control, and off working state closes valve and cold
But liquid pump can control the opening and closing of coolant pump by dynamical system, and the valve of inlet pipes is to manually control, valve at outlet
Door is temp.-control valve, and two valves and coolant pump are all in opening state when working condition, when the coolant liquid in circuit is lower than
When set temperature, the temp.-control valve at outlet can be automatically closed, so that the fluid lower than set temperature is made to work on, without
It is into radiator, has saved portion of energy.
Cooling conduit before propeller of the invention can reduce the temperature of incoming flow fluid, make the intracorporal air bubble content of incoming flow stream
It reduces, to reduce Cavitation effect.
