Description

Technical Field

[0001] This utility model relates to the field of generator technology, and specifically to a generator heat dissipation component. Background Technology

[0002] During generator operation, the engine and related components (such as the muffler) generate a large amount of heat. If heat dissipation is not timely, it will not only affect power generation efficiency and equipment lifespan, but may also cause safety hazards. Traditional generator cooling designs often focus on cooling the engine body and electrical components, while neglecting the heat dissipation of exhaust system accessories such as the muffler. Especially under high load or continuous operating environments, the surface temperature of the muffler rises significantly, forming heat accumulation around it, which not only affects its own performance, but may also cause thermal radiation interference to surrounding components.

[0003] Chinese patent document CN216278153U discloses a generator, including a stator and rotor unit, an engine, a controller, and a muffler. It also includes a cooling shroud with a first air inlet. A cooling fan is installed inside the cooling shroud and is linked to the engine. The cooling shroud has a first air outlet facing the muffler and a second air outlet facing the controller.

[0004] Chinese patent document CN222759859U discloses a fuel-fired generator set, including a chassis, a water tank, a fan, an engine, a generator, a control panel, an air filter, and an air inlet and an air outlet. The key feature is that an upper transverse ventilation channel is formed between the air inlet and the air outlet. The water tank, fan, engine, and generator are sequentially arranged within the upper transverse ventilation channel. The water tank and fan are located on one side of the air outlet, and the generator is located on one side of the air inlet. The control panel and air filter are supported above the generator by a channel bracket. The chassis forms a lower transverse ventilation channel at its lower part.

[0005] Currently, generator sets typically have mufflers connected to the engine exhaust outlet to reduce noise. However, in the aforementioned generator sets, the mufflers cannot be cooled after installation, resulting in poor heat dissipation at the muffler and making it difficult to meet the requirements for generator miniaturization. Summary of the Invention

[0006] To solve the aforementioned technical problems, this utility model provides a generator cooling assembly, including a muffler and a cooling fan. The muffler is connected to the engine. The muffler and cooling fan are fixed by a mounting mechanism, which includes an upper mounting chamber and a lower mounting chamber. The muffler is located in the upper mounting chamber, and the cooling fan is located in the lower mounting chamber. The upper mounting chamber protrudes towards the engine side, and the cavity wall of the upper mounting chamber below the muffler forms an inclined air guide surface.

[0007] To facilitate heat dissipation, the lower mounting chamber is provided with a lower ventilation hole, and the cooling fan is connected to the engine through the lower ventilation hole.

[0008] Furthermore, an upper ventilation hole is provided at the junction of the upper and lower installation chambers, and the upper ventilation hole connects both the upper and lower installation chambers.

[0009] Preferably, the mounting mechanism includes a front mounting plate, a louvered heat dissipation plate, an upper air guide plate, a lower air guide plate, and two side mounting plates. The front mounting plate and the louvered heat dissipation plate form an interconnected upper mounting chamber and a lower mounting chamber. The upper air guide plate and the lower air guide plate guide air downwards into the upper mounting chamber.

[0010] Preferably, the upper air guide plate and the lower air guide plate are inclined in the same direction.

[0011] Preferably, the two side mounting plates and the upper air guide plate form a convergence structure toward the louvered heat dissipation plate.

[0012] For easy exhaust, the muffler is connected to an exhaust pipe, which is located in the lower mounting chamber, with the exhaust port of the exhaust pipe located at the lower part of the lower mounting chamber.

[0013] For ease of installation and fixation, the exhaust port is fixed to the generator support base by a bracket.

[0014] This utility model has the following beneficial effects: This invention utilizes a cooling fan and an inclined air guide surface to create air recirculation in the upper mounting chamber, carrying away heat from the muffler. Simultaneously, the upper ventilation holes provide cooling air to both the upper and lower mounting chambers. By integrating the muffler and cooling fan into the same mounting mechanism and utilizing the layered layout of the upper and lower mounting chambers, a compact structure is achieved within a limited space, facilitating the overall miniaturization and lightweight design of the generator. The coordinated design of the air guide surface and ventilation holes not only improves heat dissipation but also guides the airflow in an orderly manner, reducing turbulence and noise. Furthermore, the lower placement of the exhaust pipe and its fixation to the bracket enhances the stability of the system structure and ease of installation. Attached Figure Description
