Description

Low Noise Generator Set

technical field

The utility model relates to the technical field of generators, in particular to a small-sized low-noise generator set.

Background technique

Enterprises, institutions, families or other places often use a small, low-noise generator set. This generator set has a housing. Since the unit generates a lot of heat when it is working, the current unit is provided with a number of vents on the housing. The natural ventilation cooling method is used to cool the unit. This cooling method can basically meet the requirements of the generator when the unit has good ventilation conditions and the ambient temperature is not high. However, in a closed high-temperature environment, the unit will be Life is shortened due to sustained high temperature.

Utility model content

The technical problem to be solved by the utility model is: in order to solve the problems raised in the background technology, the utility model provides a diesel generator set fan with large air volume, good cooling effect and low noise.

The technical solution adopted by the utility model to solve the technical problem is: a low-noise generating set, including a casing, the casing is provided with an air vent, and the casing has an exhaust hole, and the position corresponding to the exhaust hole is provided with A heat dissipation fan, the rear side of the shell is provided with an installation and inspection port, the installation and inspection port is provided with a rear cover plate mounted on the shell through screws, the exhaust hole is arranged on the rear cover plate, and the heat dissipation fan is arranged on the The inner side of the rear cover, wherein the bottom of the housing is equipped with wheels;

The cooling fan includes a hub and at least two fan blades evenly distributed in the circumferential direction of the hub, the outer edge of the fan blade is connected with a guide ring with an integrated structure, and the outer contour of the fan blade is smooth radians. the

Equipped with a forced ventilation cooling fan, the cooling effect of the unit is good, the unit works stably and has a long service life, and wheels are added to make the unit move more smoothly. The heat dissipation fan of the utility model is provided with a guide ring, so that the air volume becomes larger, the cooling effect is good, the power loss of the generator is reduced, and the noise of the heat dissipation fan is relatively small at the same time.

Description of drawings

Figure 1 is a schematic structural diagram of the utility model low-noise generating set.

Figure 2 is a schematic structural view of the cooling fan in the low-noise generator set of the present invention.

Detailed ways

As shown in Figures 1 and 2, a low-noise generator set includes a casing 1, and a vent is provided on the casing 1. The casing 1 has an exhaust hole 21, and a heat dissipation device is provided at a position corresponding to the exhaust hole 21. Fan 4, the rear side of the casing 1 is provided with an installation and inspection port, the installation and inspection port is provided with a rear cover 2 mounted on the casing 1 by screws, and the exhaust hole 21 is arranged on the rear cover 2, so The heat dissipation fan 4 is arranged on the inner side of the rear cover 2, wherein the bottom of the casing 1 is equipped with a wheel 3;

The cooling fan 4 includes a hub 5 and three wind blades 6 evenly distributed in the circumferential direction of the hub 5. The outer edge of the wind blades 6 is connected with a guide ring 7 with an integrated structure. The wind blades 6 The outer contour is a smooth arc.

What is described above is only the preferred embodiment of the present utility model. It should be pointed out that for those skilled in the art, some deformations and improvements can be made without departing from the structure of the present utility model. These should also be regarded as The scope of protection of the utility model, these will not affect the effect of the implementation of the utility model and the practicability of the patent.
