Description
Technical Field
[0001] This application relates to the field of power generation, and in particular to a generator. Background Technology
[0002] Generators play a vital role in modern society, widely used in industrial production, daily life, emergency power supply, and many other fields. With continuous technological advancements, the performance and efficiency of generators are constantly improving, providing reliable power for social development and people's lives. They not only provide power to remote areas not covered by the power grid, but also ensure the normal operation of critical facilities in emergencies such as sudden power outages, playing an indispensable role in maintaining social stability and economic development.
[0003] In traditional generators, various technical methods are typically employed to address heat dissipation issues for both the generator body and the inverter, as well as to ensure overall equipment stability and functionality. For generator body cooling, a common practice is to install specialized cooling devices, such as heat sinks or air-cooled radiators, externally to dissipate heat using air convection. For inverter cooling, independent cooling fans or water-cooling systems are generally used, employing forced convection to remove heat. Regarding equipment installation and layout, complex support structures and mounting plate designs are usually employed to ensure stable installation and rational arrangement of all components. Furthermore, to minimize interference and impact during equipment operation, different components are isolated and protected. Utility Model Content
[0004] To achieve efficient heat dissipation and extend equipment lifespan, this application provides a generator.
[0005] The generator provided in this application adopts the following technical solution: A generator includes an internal combustion engine, a generator body, cooling fan blades, cooling channels, and an inverter. The piston of the internal combustion engine moves vertically, and the internal combustion engine is used to drive the generator body to work and to drive the cooling fan blades to rotate. The cooling fan blades are used to allow outside air to flow into the cooling channel, the outlet of which is directly opposite the inverter.
[0006] By adopting the above technical solution, the piston moves vertically, and the piston's gravity will not generate a horizontal component force, so that gravity will not aggravate the wear of the piston; the internal combustion engine drives the cooling fan blades to rotate to drive airflow, and the cooling channel is used to make the airflow to the inverter to achieve inverter heat dissipation.
[0007] Preferably, it also includes a casing. The enclosure has an inlet, an opening, and the outlet. The cooling fan blades are located inside the casing. The generator body extends into the opening, and the inner wall of the casing and the surface of the generator body form the heat dissipation channel.
[0008] By adopting the above technical solution, the internal combustion engine drives the cooling fan blades to rotate, thereby driving airflow. The air flows in the cooling channel to achieve heat dissipation of the generator body; the outlet of the cooling channel allows the air to flow to the inverter to achieve heat dissipation of the inverter.
[0009] Preferably, there is a gap between the surface of the generator body and the casing. The internal combustion engine is located on the side of the generator body away from the casing.
[0010] By adopting the above technical solution, some air flows out from the gap between the generator body surface and the casing to enhance the heat dissipation of the internal combustion engine.
[0011] Preferably, it also includes a bracket and a mounting plate. The mounting plate is connected to the bracket. The internal combustion engine and generator body are connected to the bracket, and the internal combustion engine and generator body are located on one side of the mounting plate. The inverter is connected to the side of the mounting plate facing the generator body, and the other side of the mounting plate is used for mounting markings. The mounting plate is used for mounting switches and / or sockets.
[0012] By adopting the above technical solution, the installation structure is simple and easy to assemble; when personnel operate at the switch and / or socket, the mounting plate isolates the heat and personnel, which is beneficial to operational safety.
[0013] Preferably, the bracket includes a support rod and a support plate. The support rods are provided in multiple parts, and the multiple support rods are spliced together. The support plate is connected to the support rod, the support plate is horizontal, and the internal combustion engine and generator body are connected to the upper surface of the support plate.
[0014] By adopting the above technical solution, the bracket is mainly composed of support rods, which facilitates air circulation inside and outside the bracket and helps the internal combustion engine dissipate heat.
[0015] Preferably, the exhaust port of the internal combustion engine faces away from the mounting plate.
[0016] By adopting the above technical solution, the high-temperature exhaust gas is prevented from flowing into the inverter, thus ensuring the inverter's heat dissipation.
[0017] Preferably, it also includes a casing. The enclosure has an inlet, an opening, and the outlet. The cooling fan blades are located inside the casing. The generator body extends into the opening, and the inner wall of the casing and the surface of the generator body form the heat dissipation channel. The opening of the cover faces parallel to the mounting plate. The opening of the cover is oriented parallel to the mounting plate.
[0018] By adopting the above technical solution, when some air flows out from the opening, this part of the air flows in a direction parallel to the mounting plate, so that the hot air around the internal combustion engine moves away from the mounting plate, which is beneficial to the heat dissipation of the inverter.
[0019] Preferably, the surface of the inverter is provided with heat sinks, and the heat sinks are inclined.
[0020] By adopting the above technical solution, the airflow cannot completely cover the inverter due to the limited size of the outlet; after the air flows to the heat sink, the air heats up and moves obliquely upward along the heat sink, which is conducive to the full contact between the air and the heat sink, thus realizing the heat dissipation of the inverter.
[0021] Preferably, the outlet is horizontal to the inverter, and there is a gap between the outlet and the inverter.
[0022] By adopting the above technical solution, the cooling air flowing from the casing outlet to the inverter has a temperature higher than that of the outside air. Within the gap between the casing and the inverter, the cooling air has an upward trend, which causes the outside air to flow into this gap and mix with the cooling air. The mixed air then flows to the inverter, thus achieving inverter heat dissipation.
[0023] Preferably, the internal combustion engine includes a diesel engine.
[0024] By adopting the above technical solution, compared with gasoline engines, diesel engines are compression ignition engines, which can omit the ignition system (spark plugs, ignition coils, and other components).
[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The piston moves vertically, so gravity will not produce a horizontal component force, which avoids accelerating piston wear and improves equipment lifespan; 2. The internal combustion engine drives the cooling fan blades to rotate, which in turn draws air into the cooling channel. The air then flows from the channel outlet to the inverter, thus cooling the inverter. 3. The mounting plate connects to the bracket, and the internal combustion engine, generator body and inverter are connected to the bracket and mounting plate. The installation structure is simple and easy to assemble. In addition, the mounting plate can isolate hot air and personnel, which is conducive to operational safety. Attached Figure Description

[0032] Multiple support rods 11 are provided, and the multiple support rods 11 are spliced together to form a frame structure; the support rods 11 can be fixedly connected by welding. The spacing between the support rods 11 is much larger than the diameter of the support rods 11, allowing air to flow freely inside and outside the bracket 1 through the spacing between the support rods 11.
[0033] A support plate 12 is fixedly connected to a support rod 11, serving as the lower end of the bracket 1. The support plate 12 is horizontal, and the internal combustion engine 2 and the generator body 3 are fixedly connected to the upper surface of the support plate 12. Simultaneously, the orientation of the internal combustion engine 2 is adjusted so that the piston of the internal combustion engine 2 moves vertically and the crankshaft rotation axis of the internal combustion engine 2 is horizontal. The crankshaft of the internal combustion engine 2 drives the generator body 3. The internal combustion engine 2 can be a gasoline engine or a diesel engine. Preferably, the internal combustion engine 2 is a diesel engine.
[0034] The generator also includes a mounting plate 4, an inverter 51, and a heat sink 52.
[0035] Mounting plate 4 is fixedly connected to bracket 1 (connecting rod). Mounting plate 4 is vertical and parallel to the crankshaft rotation axis of internal combustion engine 2. Mounting plate 4 is located on one side of support plate 12, so that internal combustion engine 2 and generator body 3 are located on one side of mounting plate 4. Furthermore, the orientation of exhaust port 21 of internal combustion engine 2 is adjusted so that exhaust port 21 of internal combustion engine 2 faces away from mounting plate 4.
[0036] Inverter 51 is fixedly connected to the side of mounting plate 4 facing generator body 3, and there is a gap between inverter 51 and generator body 3. Heat sink 52 is fixedly connected to the side of inverter 51 facing generator body 3; multiple heat sinks 52 are provided, heat sinks 52 are perpendicular to mounting plate 4, and heat sinks 52 are inclined.
[0037] The other side of mounting plate 4 is used for mounting / affixing labels. Mounting plate 4 is used for mounting switches and / or sockets.
[0038] The generator also includes cooling fan blades and a casing 6.
[0039] The crankshaft of the internal combustion engine 2 drives the generator body 3. In this embodiment, both ends of the generator body 3's shaft extend out of the generator body 3's housing. One end of the shaft is connected to the crankshaft of the internal combustion engine 2, and the cooling fan blades are fixedly connected to the other end of the shaft. The shaft and crankshaft can be connected by a coupling, belt drive mechanism, or other means; the shaft and crankshaft can also be integrally formed. The cooling fan blades can be connected to the shaft by a key.
[0040] The casing 6 is fixedly connected to the support plate 12 and / or the generator body 3. Along a horizontal direction parallel to the mounting plate 4: one end of the casing 6 is provided with an inlet 61; the other end of the casing 6 is provided with an opening 62, and the opening 62 faces parallel to the mounting plate 4.
[0041] One end of the generator body 3 extends into the opening 62, so that the cooling fan blades are located inside the casing 6, and the internal combustion engine 2 is located on the side of the generator body 3 away from the casing 6; and there is a gap between the surface of the generator body 3 and the casing 6.
[0042] There is a gap between the casing 6 and the heat sink 52, and the surface of the casing 6 facing the mounting plate 4 has an outlet 63. Horizontally, the outlet 63 faces the inverter 51. The inner wall of the casing 6 and the surface of the generator body 3 form heat dissipation channels.
[0043] The internal combustion engine 2 operates to drive the cooling fan blades to rotate. The rotation of the cooling fan blades allows outside air to flow into the casing 6 through the inlet 61. Some air flows out from the gap between the surface of the generator body 3 and the casing 6, and the remaining air flows from the outlet 63 to the heat sink 52.
[0044] The implementation principle of a generator according to this application embodiment is as follows: the vertical piston movement of the internal combustion engine 2 reduces piston wear, improving the reliability and service life of the equipment. Simultaneously, the internal combustion engine 2 drives the cooling fan blades to rotate, creating airflow, which is guided to the inverter 51 through the cooling channels, achieving effective heat dissipation for the inverter 51. Furthermore, through reasonable layout and structural design, such as the splicing structure of the bracket 1, the gap between the casing 6 and the generator body 3, and the orientation of the exhaust port 21, the heat dissipation performance and operational safety of the equipment are further improved.
[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.
