It is now driven and rotates by power source 100.
Therefore, cooling channels 36, the first connectivity slot 41, the second connectivity slot 51, fluid provider 200, pump 300, water
Pipe 900, support rod cooling channels 704 fluid circuit is collectively formed, in ship's propeller 1 in use, propeller 800 and
Shell 500 is immersed in the water close to one end of propeller 800, and the inlet opening 502 on shell 500 is submerged in water, and water is from inlet opening
502 enter in the accommodation space 501 of shell 500, so that support rod 700 is immersed in receiving sky close to the end of propeller 800
Between in water in 501, to be cooled down to the liquid in the cooling channels 704 of support rod 700, cooling channels
Liquid after cooling, which is pumped down to, in 704 reaches pump 300 and power source 100 along fluid circuit, with cooling pump 300 and power source 100,
Constantly realize that closed loop is cooling.
In present embodiment, due to using the fluid circuit of closed loop, and being partially immersed in cooling channels 704
Mode in water radiates, so that, without sucking water from extraneous water, avoiding sucking corrosive liquid in cooling cycle process
Body or the more liquid of impurity, increase the service life of ship's propeller 1.
In other embodiments, fluid provider 200 can be omitted, at this point, being connected to power source 100 using water pipe 900
With pump 300, i.e. the first intercommunicating pore 305 passes through one of water pipe 900 and the feed pathway 43 of power source and liquid outlet channel 44 and is connected to, the
Two intercommunicating pores 306 are connected to by water pipe 900 with feed pathway 43 and the another of liquid outlet channel 44, and before use, returning to fluid
Cooling liquid is injected in road.In other embodiments, support rod 700 is not limited to using the axle sleeve in present embodiment
600 are positioned.
In other embodiments, cooling channels 704 can be opened in shell 500, and support rod 700 can save at this time
Slightly, it can external application shell 500 substitutes support rod 700 and realizes supporting role, and cooling channels 704 are provided in shell 500
When, the end face of shell 500 can open up intercommunicating pore, and to be connected to pump, inlet opening can be omitted on shell 500.Support rod 700 or shell
It 500 cross section can be streamlined or round for water-drop-shaped.
In other embodiments, it can be not limited to cooling power source and pump, can be used for cooling down other heater elements,
It only needs to be changed to fluid circuit to flow through other elements, i.e., it is same to can be achieved using other cooling yuan of the closed loop type of cooling
