Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation of a ship internal combustion engine power system, in particular to a waterwheel type intelligent heat dissipation device. Background Art

[0002] The heat dissipation and cooling of the ship's internal combustion engine power system mainly rely on the radiator. In order to improve the heat dissipation capacity of the radiator, many technical measures are adopted in the project. Commonly used technologies include configuring cooling fans, increasing the heat dissipation area of ​​the radiator, and selecting materials with strong cooling capacity as the base material for the radiator. As the temperature of the coolant in the radiator continues to rise with the driving time and the intensification of heat exchange, when the temperature rises to a certain range, the coolant in the radiator will overflow; the overflowed coolant needs to be collected by an expansion water tank. Due to the large volume of the traditional expansion water tank, it requires a large installation space in the power system; at the same time, the continuous use of the coolant in the radiator will cause the loss of coolant, so the coolant needs to be replenished in time. At the same time, due to the heat dissipation and cooling of the ship's internal combustion engine power system, when the internal combustion engine is started, the water pump starts to rotate, resulting in energy consumption and loss, which is a form of passive heat dissipation.

[0003] The expansion tank is a structural component designed to solve the problem of thermal expansion and contraction of coolant and normal consumption, and is an important part of the radiator. Since the expansion tank is closely matched with the radiator, in order for it to function properly, multiple connecting pipes are required to play the role of heat dissipation and auxiliary water tank. However, too many pipes lead to the complexity of the connection of the cooling system, high cost, heavy weight, inconvenient sealing and disassembly, etc. Summary of the invention

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] according to Figure 1 , Figure 2 As shown, the waterwheel type intelligent heat dissipation device of the present invention includes: a radiator 1 and a water chamber 4 connected to the radiator 1 through a water inlet pipe 2 and a water outlet pipe 3, so that the coolant in the radiator 1 enters the water chamber 4 through the water outlet pipe 3, and flows into the radiator 1 through the water outlet pipe 3 after being cooled by the cooling structure 5 in the water chamber 4.

[0024] In the above technical solution, the radiator 1 adopts the radiator 1 commonly used in ships, and its size can be configured according to different heat dissipation requirements; and the water chamber 4 is used to provide a place for cooling and replenishing the coolant in the radiator 1, and its size can be comprehensively determined according to the heat dissipation of the radiator 1, the amount of coolant required, and the consumption of the coolant during the adaptation period;

[0025] The cooling structure 5 is used to adjust the temperature of the coolant in the water chamber 4 and to add coolant to the radiator 1. The water chamber 4 in the present technical solution matches the specifications of the radiator 1. Generally, the water chamber 4 can be installed at the side end of the radiator 1 to help improve the compactness of the radiator 1, reduce the volume of the radiator 1 and the water chamber 4, and reduce the connecting pipes, and the material can be selected from transparent plastic.

[0026] 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 No. 1 motor 7 outside the water chamber 4. The liquid flow sensor 52 and the temperature sensor 53 are used to monitor the flow rate and temperature of the liquid in the water chamber 4, respectively.

[0027] Wherein, the liquid flow sensor 52 is arranged at the water inlet of the water chamber 4.

[0028] The PLC controller 6 is located outside the water chamber 4 and is electrically connected to the first motor 7, the liquid flow sensor 52, and the temperature sensor 53;

[0029] The working principle of the impeller 51 is: the temperature parameter of the coolant in the water chamber 4 received by the temperature sensor 53 of the PCL controller 6 and the flow parameter of the coolant flowing from the radiator 1 into the water chamber 4 monitored by the liquid flow sensor 52 determine whether to start the No. 1 motor 7 to control the operation of the impeller 51, and control the speed of the impeller 51 at the same time; according to the heat dissipation needs of the ship power assembly, in different application scenarios and working conditions, the impeller 51 with different power and different speeds is selected, and the No. 1 motor 7 that matches it can be determined. In the limited space of the water chamber 4 that can accommodate the impeller 51, the structure of the impeller 51 is designed. The structure of the impeller 51 can be adjusted according to the amount of heat dissipation, by setting the inflow angle of the impeller 51 blades, so that the coolant flowing through the impeller 51 blades has different speeds, and its speed is controlled by the speed of the No. 1 motor 7, so as to achieve different cooling effects. The connection between the No. 1 motor 7 and the impeller 51 determines whether the power of the No. 1 motor 7 can be efficiently transmitted to the impeller 51. Therefore, in order to improve the design efficiency and reduce the power loss during the transmission process, the No. 1 motor 7 and the impeller 51 are coaxially designed.

[0030] In a specific embodiment, the cooling structure 5 further includes a waterwheel 54 and a liquid level sensor 55 controlled by the PLC controller 6. The waterwheel 54 is driven by a second motor 56 outside the water chamber 4. The liquid level sensor 55 controls the opening and closing of the waterwheel 54 by monitoring the height of the liquid level in the water chamber 4.

[0031] Wherein, the liquid level sensor 55 is arranged at the water outlet of the water chamber 4.

[0032] The working principle of the waterwheel 54 is as follows: according to the requirements of heat dissipation and the amount of cooling liquid to be replenished, the waterwheel 54 rotates under the drive of the second motor 56, and the rotating waterwheel 54 transports the cooling liquid at a low position in the water chamber 4 to a high position, so as to transport the cooling liquid at a low position to the water outlet of the water chamber 4 and flow into the radiator 1, so as to complete the replenishment of the cooling liquid in the radiator 1;

[0033] During this process, when the temperature of the water chamber 4 is high, the rotation speed of the water wheel 54 can be accelerated under the drive of the second motor 56; when the temperature of the water chamber 4 is low, the water wheel 54 can rotate at a low speed or remain stationary. When the coolant in the radiator 1 is consumed too much, the water wheel 54 starts and starts to rotate to replenish the coolant in the water chamber 4 to the radiator 1 in time; when the liquid level sensor 55 in the water chamber 4 shows that the coolant level is lower than the threshold, the water wheel 54 is controlled to stop working through the PLC controller 6.

[0034] In a specific embodiment, the cooling structure 5 further includes an alarm sensor 57, and the setting height of the alarm sensor 57 in the water chamber 4 is higher than the setting height of the liquid level sensor 55 in the water chamber 4;

[0035] The alarm sensor 57 is used to monitor the liquid level in the water chamber 4 .

[0036] When the cooling liquid level in the water chamber 4 reaches the position of the alarm sensor 57, the alarm sensor 57 is triggered, and the PLC controller 6 issues an alarm upon receiving a signal from the alarm sensor 57 to inform that there is an excess of cooling liquid in the water chamber 4.

[0037] During the specific operation, the No. 1 motor 7 , the No. 2 motor 56 and the PLC controller 6 are electrically connected via a frequency converter 8 .

[0038] The present invention is achieved in that:

[0039] During the operation of the ship, since the temperature of the coolant increases with the travel distance, when the temperature rises to a certain range, the PLC controller 6 actively starts the No. 1 motor 7 and the No. 2 motor 56 according to the detected temperature sensor signal, flow sensor signal and coolant position signal, and accelerates the circulation of the coolant to reduce the coolant temperature. At the same time, through the water inlet pipe 2 and the water outlet pipe 3 of the radiator 1 and the water chamber 4, the high-temperature coolant flowing out is quickly stirred under the drive of the impeller 51 to play a cooling role; when the liquid level in the radiator 1 rises above the threshold, the water wheel 54 is started to transport the coolant stored in the water chamber 4 to the water inlet pipe 2 connecting the radiator 1 and the water chamber 4, thereby realizing the function of replenishing the radiator 1 and being able to accurately control the amount of coolant in the radiator 1.

[0040] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
