Description

Technical Field

[0001] The invention relates to the technical field of gasoline generators, and in particular to a low-noise generator set. Background Art

[0002] The main purpose of the generator set is to convert other forms of energy into the electricity we need, and the main power sources of common generator sets are gasoline engines and diesel engines, which use gasoline and diesel as fuels respectively. Gasoline engines are ignited by spark plugs, with a power generally ranging from 0.5-10kw, mainly air-cooled, small in size, easy to move, and generally used in small places such as residential areas. Diesel engines are ignited by the heat formed by compression, with a power range of 8-2000kw, mainly water-cooled, large in size, and inconvenient to move. They are mainly the main backup power supply for large fixed places such as hotels, breeding enterprises, and chemical enterprises. Among them, gasoline generator sets commonly used in small places such as residential houses usually require noise reduction mechanisms to be set on the generator sets to reduce the impact of noise generated during the operation of the generator sets on the living quality of surrounding residences.

[0003] Existing gasoline generator sets use a variety of methods to reduce the noise of the generator set, such as using a special impedance-type composite silencer to reduce the exhaust noise of the gasoline engine, and using sound insulation materials around the generator set to reduce the spread of noise, etc. Among them, gasoline generator sets currently usually use resistive plate silencers, and use sound insulation, sound absorption treatment and unit isolation in the machine room to reduce the noise of the generator set cooling fan. However, since the resistive plate silencer and the supporting noise reduction structure of the machine room still need to occupy a large space, it is difficult to achieve a good noise reduction effect in some places where it is not suitable to open up a separate machine room. Therefore, it is necessary to provide such places with a gasoline generator set that uses a more compact cooling structure and ensures low noise, and a low-noise generator set is proposed for this purpose. Summary of the invention

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present invention can realize automatic cooling of the running gasoline generator by arranging a cooling component and a heat collection component. Except for the regular replacement of the cold oil in the infusion pump, other heat exchange processes are automatically carried out without power drive, which greatly reduces the noise generated during the cooling process. At the same time, the cooling component and the heat collection component are closely distributed around the gasoline generator, with a compact structure and small space occupation, and are suitable for a variety of narrow spaces;

[0020] 2. The present invention arranges a capillary copper heat pipe so that the coolant stored in the capillary copper heat pipe absorbs heat, heats the coolant to vaporize it and moves it to the other end with a lower temperature. Under the cold oil transportation and heat exchange of the infusion pump, the cold oil box and the heat exchange oil box, the gas heat inside the capillary copper heat pipe is conducted, and will be re-condensed into coolant droplets and flow back to the heat collection end under the capillary effect to re-exchange heat. With the help of the huge latent heat of evaporation of the coolant, a large amount of heat can be transmitted even if the temperature difference is small. The capillary copper heat pipe is a capillary tube and is attached to the top of the gasoline generator, which occupies very little space and saves a lot of installation space.

[0021] 3. The present invention sets a capillary copper heat pipe. Since the interior of the outer shell is in a vacuum state, the evaporation temperature of the coolant under low pressure is greatly reduced, so that the coolant can be quickly gasified and refluxed through the inner surface of the liner shell after heat exchange condensation. The inner surface of the liner shell covered with sintered metal particles and metal wire mesh and provided with spiral grooves can enhance the wettability of the coolant, that is, enhance the capillary effect, so that the coolant can quickly reflux even if it is not in the direction of gravity, thereby ensuring the stability of heat exchange of the heat pipe fixed copper sleeve;

[0022] 4. The present invention provides a condensing sleeve, so that the cold oil circulating between the cold oil box and the heat exchange oil box, under the power of the infusion pump, is affected by the negative pressure of the oil flow and enters the spiral channel inside the condensing sleeve along the condensing oil pipe, flows along the circumferential side of the outer shell in a spiral manner and flows back to the heat exchange oil box, completing the heat exchange of the outer shell surface and the internal coolant, accelerating the condensation speed of the coolant, and improving the cooling speed of the heat pipe fixed copper sleeve on the gasoline generator;

[0023] 5. The present invention sets a cooling fan so that the cooling fan can blow air into the two multi-ventilation ducts, and then deliver cold air to each air delivery duct, so that the pipe wall of the air delivery duct can cool the cold oil inside the heat exchange oil box, so that the power circulation of the cold oil by the infusion pump and the cold air delivery of the cooling fan can cooperate with each other, which can greatly accelerate the cooling speed of the cold oil itself, so that the cold oil can be cooled quickly, and then continue to cool the heat pipe fixed copper sleeve;

[0024] 6. The present invention arranges heat dissipation fins so that the cold oil circulates inside the heat dissipation fins, thereby increasing the cooling surface area of ​​the cold oil and the heat pipe fixing copper sleeve and the capillary copper heat pipe, and enhancing the heat conduction speed. At the same time, the top of the air duct for transmitting cold air is located inside the heat dissipation fins, which can also enhance the cooling capacity of the heat dissipation fins and transmit the airflow after absorbing heat to the outside through the heat dissipation fins for diffusion. At the same time, the muffler can reduce the noise of the diffused airflow, so that the generator set maintains a low noise state;

[0025] 7. The present invention arranges the first and second sub-heat collecting rings, so that the heat collecting oil heated in the first and second sub-heat collecting rings will flow into the main heat collecting ring alternately along the second oil pipeline and the first oil pipeline at the top under the action of the Marragoni effect, and the heat collecting oil with lower temperature will circulate back to the first and second sub-heat collecting rings along the first and second oil pipelines at the bottom, thus realizing the internal circulation of the heat collecting oil, and making it convenient for the heat exchange to be carried out around the copper sleeve fixing the heat collecting pipe of the gasoline generator;

[0026] 8. The present invention arranges the metal fiber block so that the metal fiber block inside the heat exchange oil box can improve the heat transfer medium inside the heat exchange oil box by virtue of its own fibrous mass structure, so that the cold oil can flow in the gaps inside the metal fiber block, so that the cold oil and the metal fiber block can cooperate with each other to make the surrounding side of the heat pipe fixed copper sleeve in both solid and liquid heat exchange media, and further improve the cooling speed of the heat pipe fixed copper sleeve by the cold oil in the heat exchange oil box, and improve the cooling effect on components such as gasoline generators;

[0027] 9. The present invention arranges a damping spring seat so that the vibration generated by the gasoline generator will cause the support foot to swing up and down inside the damping spring seat, and the sleeve frame will also drive the middle movable end of the double-headed spring sleeve rod to slide up and down, and quickly balance under the damping effect of the damping spring seat and the double-headed spring sleeve rod, thereby greatly reducing the shaking amplitude of the gasoline generator. The gasoline generator cooperates with the silencer chassis to prevent the bottom of the gasoline generator from being in rigid contact with the ground, thereby playing a role in buffering and shock absorption, and reducing the noise generated by the gasoline generator.

[0044] The cooling component is used to cool and dissipate heat from the gasoline generator 2;

[0045] like Figure 3 As shown, the cooling assembly includes a plurality of evenly distributed heat pipe fixed copper sleeves 4 arranged on the top of the gasoline generator 2, a cold oil box 5 and two heat exchange oil boxes 7 are arranged on one side of the gasoline generator 2, and the two heat exchange oil boxes 7 are both located on the top of the cold oil box 5. The plurality of heat pipe fixed copper sleeves 4 are respectively distributed on both sides of the top of the gasoline generator 2, as shown in FIG. Figure 7 As shown, one end of the plurality of heat pipe fixing copper sleeves 4 extends to the interior of the two heat exchange oil boxes 7 respectively. Figure 4 As shown, an infusion pump 6 is fixedly installed on one side of the cold oil box 5, and the input end of the infusion pump 6 is connected to the inside of the cold oil box 5. A heat exchange oil pipe 8 is fixedly installed between the output end of the infusion pump 6 and one of the heat exchange oil boxes 7, and between the cold oil box 5 and the other heat exchange oil box 7. Figure 6 As shown, a plurality of evenly distributed circulation pipes 23 are fixedly installed between the two heat exchange oil boxes 7, and the other end of the plurality of heat pipe fixed copper sleeves 4 is provided with the same heat collecting assembly;

[0046] The heat collecting assembly is used to collect the heat generated by the gasoline generator 2 and send it to the sides of the heat pipe fixed copper sleeve 4;

[0047] like Figure 4 As shown, the heat collection assembly includes a main heat collection ring 17 fixedly sleeved on the gasoline generator 2, as shown in FIG. Figure 5As shown, the interior of the main heat collecting ring 17 is a hollow structure, and the ends of the multiple heat pipe fixing copper sleeves 4 away from the heat exchange oil box 7 all extend to the interior of the main heat collecting ring 17. In this embodiment, multiple heat conducting wires can be arranged inside the main heat collecting ring 17, and the multiple heat conducting wires form a heat conducting pipeline extending to the internal space of the gasoline generator 2, which is used to transfer the heat generated during the operation of the gasoline generator 2 to the main heat collecting ring 17 for heat collection. The cold oil box 5 and the heat exchange oil box 7 store cold oil or other cooling liquids for circulating cooling, and the main heat collecting ring 17 stores heat collecting oil or other heat collecting liquids for absorbing the heat generated by the operation of the gasoline generator 2. The cold oil and the heat collecting oil are not interconnected, and only heat exchange is performed. Specifically, the low-noise generator set is provided with a cooling component and a heat collecting component, so that the static heat collecting oil stored in the main heat collecting ring 17 can absorb the heat transferred from the peripheral side of the gasoline generator 2, and the heat collecting oil with a higher temperature will surge upward under the action of the Marraghini effect, so that the gasoline generator 2 conducts out The heat can be concentrated on the top of the main heat collecting ring 17, that is, around one end of the heat pipe fixed copper sleeve 4, so that the heat is exchanged by the heat pipe fixed copper sleeve 4, and the heat is transferred to the other end of the heat pipe fixed copper sleeve 4, that is, to the cold oil inside the heat exchange oil box 7. When the heat of the heat collecting oil around the heat pipe fixed copper sleeve 4 is conducted, the remaining heat collecting oil with a higher temperature will continue to surge up to replace the heat collecting oil with a lower temperature, and the heat exchange cycle is realized over and over again. After the cold oil in the heat exchange oil box 7 is heated up, the infusion pump 6 will transfer it through the heat exchange oil pipe 8. A large amount of spare cold oil in the cold oil box 5 is transported to the heat exchange oil box 7, and the heated cold oil is sent back to the cold oil box 5 to cool down for subsequent use, thereby realizing automatic cooling of the running gasoline generator 2. Except for the regular replacement of cold oil by the infusion pump 6, other heat exchange processes are automatically carried out without power drive, which greatly reduces the noise generated during the cooling process. At the same time, the cooling components and the heat collection components are closely distributed on the surrounding side of the gasoline generator 2, with a compact structure and small space occupation, and are suitable for a variety of narrow spaces.

[0048] like Figure 8 As shown, a plurality of capillary copper heat pipes 22 are fixedly embedded inside the heat pipe fixing copper sleeve 4 and are evenly distributed along the axis of the heat pipe fixing copper sleeve 4. Figure 5 , Figure 7 As shown, the two ends of the capillary copper heat pipe 22 respectively penetrate the two ends of the heat pipe fixing copper sleeve 4 and extend to the inside of the heat exchange oil box 7 and the main heat collecting ring 17 respectively, as shown in FIG. Fig. 9As shown, the capillary copper heat pipe 22 includes an outer shell 2201, the interior of the outer shell 2201 is in a vacuum state, the interior of the outer shell 2201 is fixedly sleeved with an inner shell 2202, the interior of the inner shell 2202 is loaded with coolant, the inner surface of the inner shell 2202 is provided with a spiral groove 2203, the inner surface of the inner shell 2202 is covered with sintered metal particles and a metal wire mesh, and the two ends of the capillary copper heat pipe 22 are raindrop-shaped structures. In this embodiment, the metal shell 401 and the inner shell 402 can be made of metal with good thermal conductivity, such as metal copper, and the inner surface of the inner shell 402 is covered with a A layer of finely sintered metal copper particles is formed, and a layer of copper wire mesh is sintered and covered on the inner surface of the copper particles, so that the copper particles and the copper wire mesh cooperate with the spiral grooves 403 to form three interlaced composite capillary structures, which can improve the adhesion of the coolant on the inner surface of the liner shell 402, so that the liquid adhering to the inner surface can provide sufficient pulling force for the coolant as a whole, thereby enhancing the capillary effect of the coolant inside the heat pipe 4 and accelerating the reflux speed of the coolant; specifically, by setting the capillary copper heat pipe 22, the coolant stored in the capillary copper heat pipe 22 will absorb the heat generated when the gasoline generator 2 is running, so that the heat is concentrated To one end of the capillary copper heat pipe 22, the coolant is heated to vaporize it, thereby absorbing a large amount of heat and moving to the other end with a lower temperature. Under the cold oil transportation and heat exchange action of the infusion pump 6, the cold oil box 5 and the heat exchange oil box 7, the gas heat inside the capillary copper heat pipe 22 is conducted, and will be re-condensed into coolant droplets and reflux to one end of the heat collection under the action of the capillary effect, and heat exchange will be carried out again. With the help of the huge latent heat of evaporation of the coolant, a large amount of heat can be transmitted even if the temperature difference is small. The capillary copper heat pipe 22 is a capillary tube and is attached to the top of the gasoline generator 2, so it occupies very little space, saving a lot of installation space, and at the same time The heat generated by the gasoline generator 2 during operation will be transferred to the coolant inside through the outer shell 2201. Since the interior of the outer shell 2201 is in a vacuum state, the evaporation temperature of the coolant under the low-pressure state is greatly reduced, so that the coolant can be quickly vaporized and reflux through the inner surface of the liner shell 2202 after heat exchange and condensation. The inner surface of the liner shell 2202 covered with sintered metal particles and metal wire mesh and provided with spiral grooves 2203 can enhance the wettability of the coolant, that is, enhance the capillary effect, so that the coolant can quickly reflux even if it is not in the direction of gravity, thereby ensuring the stability of heat exchange of the capillary copper heat pipe 22.

The heat collecting oil which is heated will flow into the main heat collecting ring 17 alternately along the second oil pipe 21 and the first oil pipe 20 which are inclined upward from the top under the action of the Marragoni effect. The heat collecting oil with a lower temperature will also circulate back to the first sub-heat collecting ring 18 and the second sub-heat collecting ring 19 along the first oil pipe 20 and the second oil pipe 21 at the bottom, thereby realizing the internal circulation of the heat collecting oil and facilitating the heat exchange of the gasoline generator 2 around the copper sleeve 4 which fixes the heat collecting pipe.

[0053] like Figure 3 , Figure 4 As shown, the gasoline generator 2 is fixedly sleeved with a first sub-heat collecting ring 18 and a second sub-heat collecting ring 19, the first sub-heat collecting ring 18 is located between the second sub-heat collecting ring 19 and the main heat collecting ring 17, the interiors of the first sub-heat collecting ring 18 and the second sub-heat collecting ring 19 are both hollow structures, a plurality of evenly distributed first oil pipelines 20 are fixedly installed between the first sub-heat collecting ring 18 and the main heat collecting ring 17, a plurality of evenly distributed second oil pipelines 21 are fixedly installed between the first sub-heat collecting ring 18 and the second sub-heat collecting ring 19, the first oil pipeline 20 and the second oil pipeline 21 are both obliquely arranged upward in the direction of the main heat collecting ring 17, in this embodiment, the first sub-heat collecting ring 18 and the second sub-heat collecting ring 19 store the same heat collecting oil as that in the main heat collecting ring 17, the first sub-heat collecting ring 18 and the second sub-heat collecting ring 19 store the same heat collecting oil as that in the main heat collecting ring 17, A plurality of heat-conducting wires may also be arranged inside 19, and a heat-conducting pipeline composed of the plurality of heat-conducting wires extends to the internal space of the gasoline generator 2, and is used to transfer the heat generated when the gasoline generator 2 is running to the first sub-heat collecting ring 18 and the second sub-heat collecting ring 19 for heat collection; specifically, by arranging the metal fiber block 16, the metal fiber block 16 inside the heat exchange oil box 7 can improve the heat transfer medium inside the heat exchange oil box 7 with the help of its own fibrous mass structure, so that the cold oil can flow in the gaps inside the metal fiber block 16, so that the cold oil and the metal fiber block 16 can cooperate with each other to make the peripheral side of the heat pipe fixing copper sleeve 4 be in both solid and liquid heat exchange media, thereby further improving the cooling speed of the cold oil in the heat exchange oil box 7 on the heat pipe fixing copper sleeve 4, and improving the cooling effect on components such as the gasoline generator 2.

[0054] like Figure 3 , Fig.10As shown, a plurality of legs 25 are fixedly installed at the bottom of the gasoline generator 2, two suspension frames 26 are fixedly installed on one side of the cold oil box 5, and one end of the two suspension frames 26 is fixedly installed on two of the legs 25, respectively. A unit bracket 27 is arranged on the peripheral side of the gasoline generator 2, and a plurality of evenly distributed muffler base frames 28 are fixedly installed on the bottom of the unit bracket 27. In this embodiment, the muffler base frame 28 is made of sound-absorbing material, and two damping spring seats 29 are fixedly installed on the top of the muffler base frame 28. The two legs 25 located on the same side are slidably installed inside the two damping spring seats 29, respectively. A sleeve frame 31 is fixedly installed around the gasoline tank 1, and four double-headed spring sleeve rods 30 are fixedly sleeved on the unit bracket 27. The four sleeve frames 31 are fixedly sleeved on the four double-headed spring sleeve rods 30, respectively. In this embodiment, the damping spring seat 29 and the damping spring seat 29 are both provided with springs and damping springs. The damper is used to buffer the vibration of the gasoline generator 2. The double-headed spring sleeve rod 30 is a double-headed sliding cylinder structure. Both ends of the double-headed spring sleeve rod 30 are fixedly sleeved on the unit bracket 27, the middle movable end is slidably sleeved with the unit bracket 27, and the sleeve frame 31 is fixedly sleeved on the movable end; specifically, by arranging the damping spring seat 29, during the operation of the gasoline generator 2, the vibration generated by the gasoline generator 2 will prompt the support foot 25 to swing up and down inside the damping spring seat 29, and the sleeve frame 31 will also drive the middle movable end of the double-headed spring sleeve rod 30 to slide up and down, and quickly balance under the damping effect of the damping spring seat 29 and the double-headed spring sleeve rod 30, thereby greatly reducing the shaking amplitude of the gasoline generator 2, so that the gasoline generator 2, in conjunction with the silencer chassis 28, the bottom of the gasoline generator 2 is not in rigid contact with the ground, thereby playing a role in buffering and shock absorption, and reducing the noise generated by the gasoline generator 2.

[0055] In summary: the heat collection process of the generator set: the static heat collection oil stored in the main heat collection ring 17 can absorb the heat transferred from the peripheral side of the gasoline generator 2, and the heat collection oil with a higher temperature will surge upward under the action of the Maracas effect, so that the heat conducted by the gasoline generator 2 can be concentrated on the top of the main heat collection ring 17, that is, around one end of the heat pipe fixed copper sleeve 4. When the heat of the heat collection oil around the heat pipe fixed copper sleeve 4 is conducted, the remaining heat collection oil with a higher temperature will continue to surge up to replace the heat collection oil with a lower temperature, and the heat exchange cycle is realized repeatedly. The first auxiliary heat collection ring 1 8 and the second auxiliary heat collecting ring 19 can exchange heat with the gasoline generator 2 and even other components, and the heat collecting oil heated by heat will also flow into the main heat collecting ring 17 alternately along the second oil pipeline 21 and the first oil pipeline 20 that are inclined upward at the top under the action of the Marragoni effect, and the heat collecting oil with a lower temperature will also circulate back to the first auxiliary heat collecting ring 18 and the second auxiliary heat collecting ring 19 along the first oil pipeline 20 and the second oil pipeline 21 at the bottom, thereby realizing the internal circulation of the heat collecting oil, so that the heat of the gasoline generator 2 is conveniently exchanged with the surrounding side of the copper sleeve 4 that fixes the heat collecting pipe;

[0056] Cooling process of the generator set: the heat collecting oil inside the main heat collecting ring 17 is exchanged with one end of the heat pipe fixed copper sleeve 4, and the heat is transferred to the other end of the heat pipe fixed copper sleeve 4, that is, transferred to the cold oil inside the heat exchange oil box 7. The coolant stored in the capillary copper heat pipe 22 inside the heat pipe fixed copper sleeve 4 will absorb the heat, so that the heat is concentrated on one end of the capillary copper heat pipe 22, and the coolant is heated to vaporize it, thereby absorbing a large amount of heat and moving to the other end with lower temperature. Under the cold oil transportation and heat exchange action of the infusion pump 6, the cold oil box 5 and the heat exchange oil box 7, the gas heat inside the capillary copper heat pipe 22 is conducted, and will be re-condensed into cooling liquid droplets and reflux to one end of the heat collection under the action of the capillary effect, and heat exchange is carried out again. With the help of the huge latent heat of evaporation of the coolant, a large amount of heat can be transmitted even if the temperature difference is small, and because the outer shell 2201 The interior of the cooling device 2202 is in a vacuum state, so that the evaporation temperature of the coolant under the low-pressure state is greatly reduced, so that the coolant can be quickly vaporized and refluxed through the inner surface of the liner shell 2202 after heat exchange and condensation. The inner surface of the liner shell 2202 covered with sintered metal particles and metal wire mesh and provided with spiral grooves 2203 can enhance the wettability of the coolant, that is, enhance the capillary effect, so that the coolant can quickly reflux even if it is not in the direction of gravity. The cold oil circulating between the cold oil box 5 and the heat exchange oil box 7 for heat exchange will be affected by the negative pressure of the oil flow under the power of the infusion pump 6, and can enter the spiral channel 14 inside the condensing sleeve 13 along the condensing oil pipe 15, flow along the circumferential side of the outer shell 2201 in a spiral manner, and reflux to the heat exchange oil box 7 to complete the heat exchange of the outer shell 2201 surface and the internal coolant, thereby accelerating the condensation speed of the coolant.

[0057] The cooling process of the cold oil itself: after the cold oil in the heat exchange oil box 7 is heated up, the infusion pump 6 will transport a large amount of cold oil in the cold oil box 5 to the heat exchange oil box 7 through the heat exchange oil pipe 8, and at the same time send the heated cold oil back to the cold oil box 5 to cool down for subsequent use. The cooling fan 9 will blow air into the two multi-ventilation pipes 10, and then transport cold air to each air delivery pipe 11, so that the pipe wall of the air delivery pipe 11 can cool down the cold oil inside the heat exchange oil box 7, and the cold oil circulates inside the heat dissipation fins 12 to increase the temperature. The large cooling surface area of ​​the cold oil, the heat pipe fixing copper sleeve 4, and the capillary copper heat pipe 22 enhances the heat conduction speed. At the same time, the top of the air supply pipe 11 for transmitting cold air is located inside the heat dissipation fin 12, which can also enhance the cooling capacity of the heat dissipation fin 12 and transport the air flow after absorbing heat to the outside through the heat dissipation fin 12 for diffusion. The power circulation of the cold oil by the infusion pump 6 and the cold air delivery by the cooling fan 9 cooperate with each other, which can greatly accelerate the cooling speed of the cold oil itself and cool the cold oil quickly.
