Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
Referring to fig. 1 and 2, the waterwheel type intelligent heat dissipation device of the present invention includes: radiator 1 and through inlet tube 2, outlet pipe 3 with hydroecium 4 of radiator 1 intercommunication for coolant liquid in the radiator 1 passes through outlet pipe 3 gets into hydroecium 4, the warp behind the cooling of hydroecium 4 internal cooling structure 5 warp outlet pipe 3 flows in radiator 1.
In the technical scheme, the radiator 1 is a radiator 1 commonly used for ships, and the size of the radiator 1 can be configured according to different radiating requirements; the water chamber 4 is a place for cooling and supplying the cooling liquid in the radiator 1, and the size of the water chamber can be comprehensively determined according to the heat dissipation capacity of the radiator 1, the required amount of the cooling liquid and the consumption of the cooling liquid in an adaptation period;

In a specific embodiment, the cooling structure 5 includes an impeller 51, a liquid flow sensor 52, and a temperature sensor 53 controlled by a PLC controller 6, the impeller 51 is driven by a motor 7 outside the water chamber 4, and the liquid flow sensor 52 and the temperature sensor 53 are respectively used for monitoring the flow rate and the temperature of the liquid in the water chamber 4;
wherein, the liquid flow sensor 52 is arranged at the water inlet of the water chamber 4.
The PLC 6 is positioned outside the water chamber 4 and is electrically connected with the first motor 7, the liquid flow sensor 52 and the temperature sensor 53;
the working principle of the impeller 51 is as follows: the PCL controller 6 receives the temperature parameter of the cooling liquid in the water chamber 4 from the temperature sensor 53 and the flow parameter of the cooling liquid flowing into the water chamber 4 from the radiator 1 and monitored by the liquid flow sensor 52 to determine whether to start the first motor 7 to control the impeller 51 to work and control the rotation speed of the impeller 51; according to the heat dissipation requirement of the ship power assembly, under different application scenes and working conditions, impellers 51 with different powers and different rotating speeds are selected, and the motor 7 matched with the impellers can be determined. In the limited space where the water chamber 4 can accommodate the impeller 51, the impeller 51 structure is designed, and the impeller 51 structure can make the cooling liquid flowing through the blades of the impeller 51 have different speeds by setting the inflow attack angle of the blades of the impeller 51 according to the magnitude of heat dissipation, and the rotating speed of the first motor 7 is controlled by the rotating speed thereof, so as to achieve different cooling effects. The connection between the motor 7 and the impeller 51 determines whether the power of the motor 7 can be efficiently transmitted to the impeller 51, and therefore, in order to improve the design efficiency and reduce the power loss during the transmission process, the motor 7 and the impeller 51 are designed coaxially.
In a specific embodiment, the cooling structure 5 further includes a water wheel 54 controlled by the PLC controller 6, and a liquid level sensor 55, wherein the water wheel 54 is driven by a second motor 56 outside the water chamber 4, and the liquid level sensor 55 controls the on/off of the water wheel 54 by monitoring the height of the liquid level in the water chamber 4;
wherein, the liquid level sensor 55 is arranged at the water outlet of the water chamber 4.

in the process, when the temperature of the water chamber 4 is high, the rotation speed of the water wheel 54 can be increased under the driving of the second motor 56; when the temperature of the water chamber 4 is low, the waterwheel 54 can rotate at a low speed or does not move, and when the coolant in the radiator 1 is excessively consumed, the waterwheel 54 starts to rotate to timely supply the coolant in the water chamber 4 to the radiator 1; when the liquid level sensor 55 in the water chamber 4 displays that the cooling liquid level is lower than the threshold value, the water wheel 54 is controlled to stop working through the PLC 6.

In the specific operation process, the first motor 7, the second motor 56 and the PLC 6 are electrically connected through a frequency converter 8.
The invention is realized by the following steps:
in the running process of the ship, because the temperature of the cooling liquid is continuously increased along with the running distance, when the temperature is increased to a certain range, the PLC 6 actively starts the first motor 7 and the second motor 56 according to the detected temperature sensing signal, the flow sensing signal and the position signal of the cooling liquid, and the effect of reducing the temperature of the cooling liquid is achieved by accelerating the circulating flow of the cooling liquid. Meanwhile, the flowing high-temperature cooling liquid is rapidly stirred under the driving of the impeller 51 through the radiator 1 and the water inlet pipe 2 and the water outlet pipe 3 of the water chamber 4, so that the cooling effect is achieved; when the liquid level in the radiator 1 rises above a threshold value, the waterwheel 54 is activated to transfer the coolant stored in the header tank 4 into the inlet tube 2 connecting the radiator 1 and the header tank 4, thereby achieving a function of replenishing the radiator 1 and accurately controlling the amount of the coolant in the radiator 1.
