Description

Technical Field

[0001] This application relates to the field of generator set technology, and in particular to a compact generator set. Background Technology

[0002] With the rapid growth in demand for electricity from industry, transportation, and emergency use, high-power generator sets play a crucial role in ensuring power supply. The continuous operation of industrial production, the stable operation of transportation, and the power supply in emergency scenarios all rely on high-power generator sets, which provide stable power support for various production activities.

[0003] In traditional technologies, high-power generator sets typically have complex internal structures to meet high power output requirements, with loosely arranged components such as engines, generators, and cooling systems. This results in a large generator set size, which is difficult to adapt to space-constrained scenarios such as vehicle-mounted mobile power supplies. It cannot meet the space requirements of these scenarios and needs improvement.

[0004] Therefore, in order to solve the problem that the large size of traditional high-power generator sets limits their application scenarios, this application provides a compact generator set. Utility Model Content

[0005] To address the problem of traditional high-power generator sets being too bulky and thus limiting their application scenarios, this application provides a compact generator set.

[0006] This application provides a compact generator set, which adopts the following technical solution:

[0007] A compact generator set includes a housing with an air inlet and an air outlet. An engine, a generator, a muffler, and a radiator are housed inside the housing. The radiator and muffler are positioned above the engine and generator, and the air outlet is located on the top of the housing corresponding to the radiator.

[0008] By adopting the above technical solution, the radiator and muffler are placed above the engine and generator, achieving a compact longitudinal layout of the core components of the generator set. This breaks the problem of excessive axial length caused by the side or rear placement of the radiator in traditional generator sets, effectively shortening the overall axial dimension of the generator set. This makes the generator set adaptable to space-constrained scenarios such as vehicle-mounted units, solving the problem of the large size of traditional generator sets limiting their application scenarios. The combination of the air outlet and air inlet on the housing forms a basic airflow path, providing a structural basis for efficient heat dissipation. Furthermore, the placement of the air outlet corresponding to the radiator on the top of the housing facilitates heat dissipation and improves heat dissipation efficiency.

[0009] Preferably, the housing includes an outer shell and a base, the air outlet is located on the top of the outer shell, and the air inlet is located on the base.

[0010] By adopting the above technical solution, the air outlet is set on the top of the casing and the air inlet is set on the base. The relatively low ambient air temperature near the ground is used to improve the cooling efficiency, meet the basic requirements of engine combustion and generator cooling, and at the same time achieve deep cooling of the radiator and muffler.

[0011] Preferably, the air inlet is provided with an air inlet louver.

[0012] By adopting the above technical solution, an air inlet louver is installed at the air inlet, which can filter dust, debris and other impurities in the outside air, preventing them from entering the generator set and affecting the operational stability of core components such as the engine and generator, thereby improving the reliability of the unit in complex environments.

[0013] Preferably, the fan of the radiator is embedded on the upper surface of the radiator, and the fan of the radiator adopts backward-curved blades.

[0014] By adopting the above technical solution, the fan of the radiator is embedded on the upper surface of the radiator, avoiding the space occupied by the fan in the longitudinal direction, further shortening the longitudinal length of the generator set and making the structure more compact; while the fan of the radiator adopts backward-curved blades with better aerodynamic performance, which can efficiently guide the hot airflow to be discharged, further improving the heat dissipation efficiency.

[0015] Preferably, a rain-collecting tray is provided between the radiator, the engine, and the generator. The rain-collecting tray has a fan exhaust hole to facilitate the radiator's fan to draw out hot air, and a rain cap is provided directly above the fan exhaust hole. A rain-protecting railing is erected on the rain-collecting tray along the circumference of the fan exhaust hole, and a drainage hole is provided on the rain-collecting tray.

[0016] By adopting the above technical solution, the rain-collecting tray is set between the radiator, engine, and generator and has a fan exhaust hole, which facilitates the radiator fan to extract hot air and ensures the normal operation of the cooling system. The rain cap is set directly above the fan exhaust hole and can intercept falling rainwater, allowing the rainwater to flow along the edge to the rain-collecting tray. The rain guardrail is erected on the rain-collecting tray along the circumference of the fan exhaust hole, which can prevent rainwater from dripping and splashing into the fan exhaust hole along the rain cap. The drainage hole can drain the rainwater collected by the rain-collecting tray. Through the synergistic effect of these components, zero water seepage can be achieved in extreme weather conditions, solving the problem of rainwater seepage affecting the operation of the generator set in outdoor mobile scenarios.

[0017] Preferably, the fan exhaust vent, rain cap, and rain guard constitute a rain protection unit, and the number and position of the rain protection unit correspond one-to-one with the number and position of the radiator fan.

[0018] By adopting the above technical solution, the number and position of the rainproof units correspond one-to-one with the fans of the radiator, ensuring that the air intake area of ​​each fan can obtain independent rainproof protection, improving the uniformity and reliability of overall rain protection, and ensuring the smooth air intake and rainproof effect of each fan.

[0019] Preferably, the rain cap is tapered.

[0020] By adopting the above technical solution, the rain hat adopts a conical design, which can utilize the guiding characteristics of the conical slope to quickly guide the intercepted rainwater to the edge, thus preventing rainwater from accumulating at the top of the rain hat.

[0021] Preferably, the housing is provided with a cover, the silencer is located inside the cover, and the side of the cover away from the radiator is open. A bypass pipe is provided on the cover, and the bypass pipe connects the cover to the air inlet area of ​​the radiator.

[0022] By adopting the above technical solution, the side of the cover away from the radiator is set with an opening, allowing air to enter the cover to cool the muffler. The bypass pipe connects the cover to the air intake area of ​​the radiator, which can guide the hot airflow in the heat dissipation area of ​​the muffler to the air intake area of ​​the radiator. The local negative pressure formed by the radiator fan accelerates the discharge of hot airflow, avoids heat backflow affecting the air intake of the radiator, and ensures that the heat dissipation efficiency of the radiator is not affected by the high temperature exhaust gas.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By placing the radiator and muffler above the engine and generator, the axial length can be shortened, the size of the generator set can be reduced, and the problem of the large size of traditional high-power generator sets leading to limited application scenarios can be solved. At the same time, the fan of the radiator is embedded on the upper surface of the radiator, avoiding the space occupied by the fan in the longitudinal direction, further shortening the longitudinal length of the generator set and making the structure more compact.

[0025] 2. The installation of rain catchers, rain caps, and rain guardrails can prevent rainwater from entering the generator set through the radiator fan in extreme weather conditions, achieving zero water seepage in extreme weather and solving the problem of rainwater seepage affecting the operation of the generator set in outdoor mobile scenarios;

[0026] 3. The bypass pipe can guide the hot airflow from the muffler's heat dissipation area to the radiator's air intake area, and use the local negative pressure created by the radiator's fan to accelerate the discharge of hot airflow, avoiding heat backflow from affecting the radiator's air intake and ensuring that the radiator's heat dissipation efficiency is not affected by the high-temperature exhaust gas.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

[0032] This application discloses a compact generator set.

[0033] Reference Figure 1 and Figure 2 A compact generator set includes a housing 1 with an air inlet 2 and an air outlet 3. An engine 4, a generator 5, a muffler 6, and a radiator 7 are housed inside the housing 1. The radiator 7 and muffler 6 are positioned above the engine 4 and generator 5, and the air outlet 3 is located at the top of the housing 1 corresponding to the radiator 7. In this embodiment, the radiator 7 has a flat structure (thickness ≤ 100mm) and extends along the width of the generator set, occupying longitudinal space rather than axial space. The housing 1 includes an outer shell 11 and a base 12. The engine 4 and generator 5 are fixed to the base 12. The air outlet 3 is located at the top of the outer shell 11, and the air inlet 2 is located on the base 12. An air inlet louver 121 is fixedly connected to the base 12 at the air inlet 2.

[0034] In practical use, the radiator 7 and muffler 6 are placed above the engine 4 and generator 5, which realizes the longitudinal compact layout of the core components of the generator set, improves the problem of excessive axial length of traditional generator sets, and makes the unit adaptable to space-constrained scenarios such as vehicle-mounted units. The flat structure of the radiator 7 further reduces the longitudinal space occupied by the unit, making the unit structure more compact.

[0035] During the air intake phase, outside natural air is drawn into the unit through the air intake louvers 121 at the air intake 2 on the base 12, serving as the initial source of cooling and airflow. The bottom air intake can draw in ambient air with relatively low temperature near the ground, improving cooling efficiency. At the same time, the air intake louvers 121 can filter dust, debris, and other impurities in the outside air, preventing them from entering the generator set and affecting the operational stability of core components. After the outside natural air enters the unit, part of it provides clean air intake for the combustion of the engine 4, while the other part of the air flows directly to the generator 5 to provide initial cooling for the generator 5 body. Subsequently, the hot airflow inside the housing 1 is drawn out by the fan 71 of the radiator 7 and discharged through the air outlet 3, thereby reducing the overall temperature of the engine 4.

[0036] Reference Figure 1 and Figure 2 The fan 71 of the radiator 7 is embedded in the upper surface of the radiator 7, and the fan 71 of the radiator 7 adopts backward-curved blades. In this embodiment of the application, the fan 71 of the radiator 7 adopts ultra-thin backward-curved blades (thickness ≤ 50mm). In actual use, the fan 71 embedded in the upper surface of the radiator 7 avoids the space occupation of the fan 71 in the longitudinal direction, further shortens the longitudinal length of the generator set, and makes the structure more compact. The fan 71 of the radiator 7 adopts ultra-thin backward-curved blades with better aerodynamic performance, and combined with the air outlet 3 at the top of the housing 1 to achieve exhaust heat dissipation, it can efficiently guide the hot airflow to be discharged, and further improve the heat dissipation efficiency.

[0037] Reference Figure 1 and Figure 2 A rain-collecting plate 8 is provided between the radiator 7, the engine 4, and the generator 5. In this embodiment, the rain-collecting plate 8 extends outward from the air intake area of ​​the fan 71, forming an inverted funnel-shaped intercepting area. Connecting rods 82 are fixedly connected to both sides of the rain-collecting plate 8 along the width direction of the unit, and the end of any connecting rod 82 away from the rain-collecting plate 8 is fixedly connected to the side wall of the radiator 7. A fan exhaust hole 811 is provided on the rain-collecting plate 8 to facilitate the extraction of hot air by the fan 71 of the radiator 7. A rain cap 812 is provided directly above the fan exhaust hole 811, and the rain cap 812 is conical. In this embodiment, the cone angle of the slope of the rain cap 812 is set at 60°, and three support rods 83 are arranged in an array around the rain cap 812 on the rain receiving plate 8. One end of any support rod 83 is fixedly connected to the rain cap 812, and the other end is fixedly connected to the rain receiving plate 8. A rain guardrail 813 is erected around the fan exhaust hole 811 on the rain receiving plate 8 and is fixedly connected to the rain receiving plate 8. Drainage holes 84 are opened on the rain receiving plate 8. In this embodiment, four drainage holes 84 are arranged in a rectangular array and are located at the four corners of the rain receiving plate 8.

[0038] In practical use, the connecting rod 82 fixes the rain-collecting tray 8 directly below the radiator 7. The fan exhaust hole 811 on the rain-collecting tray 8 facilitates the extraction of hot air by the fan 71 of the radiator 7, ensuring the normal operation of the heat dissipation system. The rain cap 812 is located directly above the fan exhaust hole 811 and is cone-shaped. It can intercept falling rainwater and utilize the guiding characteristics of the cone-shaped inclined surface to quickly guide the intercepted rainwater to the edge and flow to the rain-collecting tray 8. At the same time, the support rod 83 creates a gap between the rain cap 812 and the fan exhaust hole 811, ensuring that the fan 71 of the radiator 7 can smoothly extract hot air. The rain guardrail 813 is erected on the rain-collecting tray 8 along the circumference of the fan exhaust hole 811, which can prevent rainwater from dripping and splashing into the fan exhaust hole 811 along the rain cap 812. The drain hole 84 can drain the rainwater collected by the rain-collecting tray 8. Through the synergistic effect of the above components, zero water seepage can be achieved, thereby solving the problem of rainwater seepage affecting the operation of the generator set in outdoor mobile scenarios.

[0039] Reference Figure 2 and Figure 3 The fan exhaust vent 811, rain cap 812, and rain guard 813 constitute a rain-proof unit 81. The number and position of the rain-proof units 81 correspond one-to-one with the number and position of the fans 71 of the radiator 7. In this embodiment, four fans 71 of the radiator 7 are arranged in a rectangular array on the upper surface of the radiator 7, and four rain-proof units 81 are also arranged on the rain receiving plate 8 corresponding to the number and position of the fans 71 of the radiator 7. In actual use, the number and position of the rain-proof units 81 correspond one-to-one with the fans 71 of the radiator 7, ensuring that each fan 71 of the radiator 7 can smoothly receive air and that each air intake area can obtain independent rain protection, thus ensuring the smooth air intake and rainproof effect of each fan 71.

[0040] Reference Figure 1 and Figure 2 The housing 1 contains a cover 9, and the muffler 6 is located inside the cover 9. The cover 9 is open on the side away from the radiator 7. A bypass pipe 91 is connected to the cover 9, and the bypass pipe 91 connects the cover 9 to the air intake area of ​​the radiator 7. In actual use, air enters the cover 9 through the opening side to cool the muffler 6. The bypass pipe 91 connects the cover 9 to the air intake area of ​​the radiator 7, guiding the hot airflow from the heat dissipation area of ​​the muffler 6 to the air intake area of ​​the radiator 7. The local negative pressure formed by the fan 71 of the radiator 7 accelerates the discharge of hot airflow, avoiding heat backflow from affecting the air intake of the radiator 7, and ensuring that the heat dissipation efficiency of the radiator 7 is not affected by the high-temperature exhaust gas.

[0041] Reference Figure 1In this embodiment, the enclosure 1 is also equipped with an electronic control system 10. The electronic control system 10 can monitor the operating status of each component in the unit in real time and make automatic adjustments. At the same time, it can monitor the temperature inside the enclosure 1 in real time and realize graded temperature control. When the temperature is low, it controls the fan 71 of the radiator 7 to maintain ultra-quiet operation at 300-800rpm to maintain basic heat dissipation. When the temperature is high, it intelligently speeds up to 2000-2150rpm to optimize wind noise while ensuring heat dissipation efficiency.

[0042] The implementation principle of this application embodiment is as follows: by optimizing the layout of core components to achieve a compact structure, the radiator 7 and muffler 6 are placed above the engine 4 and generator 5 to achieve a compact longitudinal layout, which improves the problem of excessive axial length of traditional generator sets. At the same time, the use of a flat radiator 7 and a fan 71 embedded on its surface further reduces the longitudinal space occupation, making the unit adaptable to space-constrained scenarios such as vehicle-mounted units. The heat dissipation efficiency is improved through reasonable air intake and exhaust design. The air intake louvers 121 at the air intake 2 on the base 12 are used to draw in the outside natural air as the initial source of cooling and air source. The bottom air intake can draw in the ambient air near the ground with a relatively low temperature, improving the cooling efficiency. At the same time, the air intake louvers 121 can filter dust, debris and other impurities in the outside air to prevent them from entering the generator set and affecting the operational stability of the core components.

[0043] After the outside natural air enters the unit, part of it is used for combustion in the engine 4, and the other part is used to initially cool the generator 5. Then, the hot air is drawn out by the fan 71 of the radiator 7 and discharged through the air outlet 3 at the top of the housing 1. At the same time, the fan 71 of the radiator 7 adopts a backward-curved blade with better aerodynamic performance to further enhance the exhaust efficiency. The side of the cover 9 away from the radiator 7 is set with an opening to facilitate the air to enter the cover 9 to cool the muffler 6. The bypass pipe 91 connects the cover 9 to the air intake area of ​​the radiator 7, and guides the hot air from the heat dissipation area of ​​the muffler 6 to the air intake area of ​​the radiator 7. The fan 71 is used to draw air to form a local negative pressure to accelerate the discharge of hot air, so as to avoid the heat backflow affecting the air intake of the radiator 7.

[0044] A fan exhaust hole 811 is provided on the rain collection tray 8 to facilitate the extraction of hot air by the fan 71 of the radiator 7, ensuring the normal operation of the heat dissipation system. The rain protection unit 81 is composed of the fan exhaust hole 811, the conical rain cap 812, and the rain protection fence 813. Combined with the drainage hole 84, the rainwater collected by the rain collection tray 8 is discharged to achieve zero water leakage and prevent rainwater from seeping in during outdoor mobile scenarios and affecting the operation of the generator set. At the same time, the number and position of the rain protection unit 81 correspond one-to-one with the fan 71 of the radiator 7, ensuring that the fan 71 of each radiator 7 can smoothly intake air and that each air intake area can obtain independent rain protection. In this embodiment, the generator set uses an electronic control system 10 to monitor the operating status in real time, and balances heat dissipation efficiency and wind noise through graded temperature control, ultimately achieving a comprehensive effect of compact structure, efficient heat dissipation, rain protection, and optimized noise.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
