Description

Technical Field

[0001] This invention relates to the field of water-cooled heat dissipation equipment technology, specifically a water-cooled heat dissipation system for generator sets. Background Technology

[0002] A generator set is a device that converts other forms of energy (such as diesel, gasoline, natural gas, biomass energy, etc.) into electrical energy. Its core consists of a prime mover (such as a diesel engine, gasoline engine, or gas turbine) and a generator. The prime mover generates mechanical energy by burning fuel, which drives the generator to rotate, ultimately converting the mechanical energy into electrical energy through electromagnetic induction.

[0003] Common heat dissipation methods for generator sets include air cooling and water cooling. Among them, water cooling is widely used in medium and large generator sets due to its high heat dissipation efficiency and stable temperature control. In the water cooling process, a water pump is used to provide power so that the coolant passes through the pipes and through the high-temperature area of ​​the generator set to carry away the heat source. Then, the radiator tank is used to cool the high-temperature coolant. After the coolant is cooled from a high temperature to a low temperature, it circulates through the generator set to achieve efficient cooling.

[0004] Traditional radiator tanks use fins on the outside and a fan to blow air to dissipate heat from the coolant inside. However, when the generator set temperature is high, the coolant discharged during the coolant transfer process is also at a high temperature. When the hot coolant flows from the radiator tank to the outlet, the radiator tank cannot cool the coolant quickly enough, resulting in a small temperature difference between the discharged coolant and the hot coolant. Consequently, when the coolant flows back into the generator set, the heat dissipation effect is poor, and the water cooling effect is inadequate. Summary of the Invention

[0005] The purpose of this invention is to provide a water-cooled heat dissipation system for generator sets, in order to solve the problem mentioned in the background art that when the coolant in the water tank of a traditional water-cooling system is cooled down, the coolant is not cooled to the specified low temperature in time before being discharged, resulting in poor heat dissipation effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a generator set water-cooled heat dissipation system, comprising a generator set, wherein the generator set is provided with an inlet port and an outlet port for water cooling connection, and further comprising two heat dissipation tanks disposed outside the generator set, the two heat dissipation tanks being fixed to the outside of the generator set by a bracket, and heat dissipation fins being fixed to the outside of the heat dissipation tanks, an inlet connecting pipe being fixed to the upper end of the two heat dissipation tanks, and an outlet connecting pipe being fixed to the bottom of the two heat dissipation tanks, an inlet pipe being fixedly connected to the outlet port on the inlet connecting pipe, an outlet pipe being fixedly connected to the outlet connecting pipe, and an installation frame disposed below the heat dissipation tanks, wherein an adjusting component is installed on the installation frame, and a heat dissipation component is disposed within the installation frame, the heat dissipation component being moved below the two heat dissipation tanks by the adjusting component, and a valve component being installed on the outlet connecting pipe, the outlet liquid being adjusted by the valve component.

[0009] Preferably, the heat dissipation component includes a heat dissipation frame, a plurality of fans are installed inside the heat dissipation frame, a plurality of air outlets are opened on the top of the heat dissipation frame, an air inlet pipe is fixedly connected to the bottom of the heat dissipation frame, and an abutment plate adapted to the abutment end is fixed on the outside of the heat dissipation frame.

[0010] Preferably, a section of spring tube is provided on the intake pipe, and the intake pipe is L-shaped and passes through the bottom of the generator set.

[0011] Preferably, the adjusting component includes two lead screws rotatably mounted on the mounting frame.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figure 1 - Figure 4 The diagram shows a generator set water cooling system, including a generator set 1, with an inlet port 2 and an outlet port 3 for water cooling connection, and two cooling water tanks 4 located outside the generator set 1. The two cooling water tanks 4 are fixed to the outside of the generator set 1 by brackets, and heat dissipation fins 5 are fixed to the outside of the cooling water tanks 4. An inlet pipe 6 is fixed to the upper end of the two cooling water tanks 4, and an outlet pipe 7 is fixed to the bottom of the two cooling water tanks 4. An inlet pipe 8 connected to the outlet port 3 is fixed to the inlet pipe 6, and an outlet pipe 9 connected to the inlet port 2 is fixed to the outlet pipe 7. A mounting frame 10 is located below the cooling water tanks 4, with an adjustment component 11 installed on the mounting frame 10. A heat dissipation component 12 is installed inside the mounting frame 10. The adjustment component 11 drives the heat dissipation component 12 to move below the two cooling water tanks 4. A valve component 13 is installed on the outlet pipe 7 to adjust the liquid discharge from the two cooling water tanks 4.

[0029] In this scheme, two cooling water tanks 4 are set up. The inlet pipe 6, the outlet pipe 7, the inlet pipe 8, and the outlet pipe 9 work together to transfer the coolant to the generator set 1 for circulation. The designed adjustment component 11 drives the heat dissipation component 12 to dissipate heat from a specific cooling water tank 4. At the same time, the valve component 13 is triggered to control the cooling water tank 4 that is dissipating heat to stop dissipating heat, thereby achieving targeted heat dissipation. The two cooling water tanks 4 discharge heat in turn to achieve targeted operation of heat dissipation and discharge, thereby improving the heat dissipation effect of the coolant. At the same time, it ensures that the coolant entering the generator set 1 is always at a low temperature, which improves the heat dissipation effect of the generator set 1.

[0030] It should also be noted that temperature sensors are installed at both ends of the liquid outlet connecting pipe 7 at the bottom of the two heat dissipation tanks 4 to detect the liquid outlet temperature. When the liquid outlet temperature reaches the set temperature, the heat dissipation component 12 is moved accordingly by the adjustment component 11 to perform targeted heat dissipation.

[0031] For further details, please refer to [link / reference]. Figure 3 , Figure 6 as well as Figure 7 The valve component 13 includes a valve pipe 14 fixed on the outlet connecting pipe 7. The outlet pipe 9 is fixedly connected to the top middle of the valve pipe 14. A valve plate 15 is slidably inserted inside the valve pipe 14. A docking post 16 is fixed inside the valve plate 15. A docking ring 17 that matches the docking post 16 is fixed at both ends of the valve pipe 14. A connecting frame 18 is fixed on the two heat dissipation tanks 4. An adjusting component 19 is fixed on the connecting frame 18. An adjusting pipe 20 that is fixedly connected to both ends of the valve pipe 14 is fixed on the two adjusting components 19. The valve plate 15 is in contact with the inner wall of the valve pipe 14. The width of the valve plate 15 is smaller than the inner diameter of the outlet pipe 9 to avoid blockage of the outlet pipe 9 when the valve plate 15 is at the outlet pipe 9.

[0032] The adjusting assembly 19 includes an adjusting column 21 fixed on the connecting frame 18. A piston rod 22 is slidably inserted inside the adjusting column 21. An abutting end 23 is fixed to the outer end of the piston rod 22. The tail end of the adjusting column 21 is fixedly connected to the adjusting pipe 20 and to the end of the valve pipe 14 away from the adjusting column 21. It should also be noted that the inner end of the piston rod 22 and the inner wall of the adjusting column 21 are fixed with mutually repelling magnetic blocks. Without external force, the piston rod 22 will move outward.

[0033] In this scheme, the heat dissipation component 12 moves to abut against the opposing end 23, causing the piston rod 22 to move within the adjusting column 21, squeezing the internal coolant. The squeezed coolant is then forced through the adjusting pipe 20 to push the valve pipe 14 away from the squeezed piston rod 22. This causes the valve plate 15 inside the valve pipe 14 to face the squeezed piston rod 22, blocking the heat dissipation tank 4 at the squeezed piston rod 22 end, preventing the heat dissipation tank 4 from discharging coolant. The other heat dissipation tank 4 then begins to discharge coolant.

[0034] For further details, please refer to [link / reference]. Figure 3 - Figure 5 The heat dissipation component 12 includes a heat dissipation frame 24, a number of fans are installed inside the heat dissipation frame 24, a number of air outlets 25 are opened on the top of the heat dissipation frame 24, an air inlet pipe 26 is fixedly connected to the bottom of the heat dissipation frame 24, and an abutment plate 27 adapted to the abutment end 23 is fixed on the outside of the heat dissipation frame 24.

[0035] Also see Figure 2 , Figure 4 as well as Figure 5 The adjusting component 11 includes two lead screws 29 rotatably mounted on the mounting frame 10. The lead screws 29 are threadedly connected to the outer end of the heat sink frame 24. Gears 30 are fixed to the outer ends of the two lead screws 29. A synchronous belt 31 is meshed on the outer ends of the two gears 30. An adjusting motor 32 is fixed on the mounting frame 10 via a motor frame. The output end of the adjusting motor 32 is fixed to the outer end of the lead screws 29 via a coupling.

[0036] It should be noted that by adjusting the motor 32 to provide power, the lead screw 29 is rotated. With the help of the timing belt 31 and the gear 30, the two lead screws 29 rotate synchronously, driving the heat sink 24 to move accordingly. After moving to the bottom of a certain heat sink 4, the heat sink 4 is specifically cooled.

[0037] It should also be noted that the multiple air vents 25 on the heat sink frame 24 are arranged in two rows on the surface of the heat sink frame 24, corresponding to the heat sink fins 5 on both sides of the heat sink 4. The air is blown by the fan inside the heat sink frame 24, and the air in the air intake pipe 26 is blown through the air vents 25 toward the heat sink fins 5 on the outside of the heat sink 4. This targeted blowing improves the heat dissipation efficiency of the coolant in the heat sink 4. The outward-extending air intake pipe 26 can be connected to an external cold source to provide cold air and improve the heat dissipation effect.

[0038] In this design, a section of spring tube 28 is installed on the air intake pipe 26. The air intake pipe 26 is L-shaped and passes through the bottom of the generator set 1. The design of the spring tube 28 allows the heat dissipation frame 24 to move below the two heat dissipation tanks 4. The air intake pipe 26 draws in low-temperature gas at a distance away from the generator set 1 to dissipate heat from the heat dissipation tanks 4 in the high-temperature environment. Compared with the traditional fan cooling method, it can cool down faster.

[0039] For further details, please refer to [link / reference]. Figure 4 A liquid filling pipe 35 is fixedly connected to the heat dissipation tank 4, and a sealing cap is installed on the liquid filling pipe 35. An expansion pipe 36 is fixed between the two heat dissipation tanks 4, and a buffer pipe 37 is fixedly connected to the bottom of the expansion pipe 36 on the liquid inlet pipe 8.

[0040] In this design, the function of the coolant filling pipe 35 is to replenish and add coolant. When the coolant temperature reaches the critical value, it will boil over. The expansion pipe 36 can effectively maintain the pressure within the coolant circulation.

[0041] In this scheme, the principle of efficient water cooling for generator set 1 is as follows:

[0042] First, the personnel fill the two radiator tanks 4 and the radiator pipes and areas where the coolant needs to circulate with the generator set 1 with coolant, and use a water pump to provide power so that the coolant circulates between the radiator tanks 4 and the generator set 1 to dissipate heat.

[0043] When the temperature sensor detects that the temperature at the bottom outlet of one of the radiator tanks 4 is too high, the high-temperature coolant will be transferred to the generator set 1 during the flow of coolant, reducing the coolant's ability to carry away heat within the generator set 1. At this time, the adjusting component 11 drives the heat dissipation component 12 to move to the high-temperature radiator tank 4, and the abutting plate 27 connects with the abutting end 23, causing the piston rod 22 to move toward the inner wall of the adjusting column 21, squeezing the coolant in the adjusting column 21, causing the coolant to squeeze one end of the valve pipe 14, causing the valve plate 15 to move toward the outlet connecting pipe 7 of the high-temperature radiator tank 4, and using the abutting column 16 to abut with the abutting ring 17 to block the high-temperature radiator tank 4, and begin targeted heat dissipation treatment at the high-temperature radiator tank 4, while the coolant in the other low-temperature radiator tank 4 begins to flow and cool the generator set 1.

[0044] Similarly, after draining the coolant from one of the radiator tanks 4 for a period of time, the temperature sensor detects that the drained coolant temperature has reached the specified temperature. At this time, the cooling component 12 is reset by the adjusting component 11, and the valve component 13 starts to drain the coolant from the other radiator tank 4 to ensure that the coolant passing through the generator set 1 is always a low-temperature coolant.

[0045] In this scheme, two radiator tanks 4 are used to alternately discharge coolant and provide targeted heat dissipation, so that the temperature difference between the coolant discharged from the radiator tank 4 and the generator set 1 is large enough, resulting in better water cooling effect. Compared with the traditional method of cooling the coolant while discharging it, this method can cool the coolant better.

[0046] Example 2: Please refer to Figure 4This embodiment further explains the first embodiment, the difference being that the interior of the heat dissipation tank 4 is optimized to improve the cooling effect of the internal coolant during circulation.

[0047] Specifically, several isolation plates 33 are fixed inside the radiator 4. A water outlet 34 is provided between the isolation plate 33 and the inner wall of one side of the radiator 4, so that the coolant flows in an S-shape. The isolation plate 33 increases the travel path of the coolant in the radiator 4, so that the coolant can extend its cooling time when cooling down, and the coolant can be cooled more evenly. The S-shaped flow also increases the heat transfer efficiency of the coolant, making it easier to cool down.
