Abstract

The utility model relates to a ventilation structure of a mute generating set, belonging to the technical field of an air-flow control part, which is characterized in that a baffle parallel to a housing of the generating set is arranged in a refluxing chamber which is divided into a front cavity and a rear cavity with the same area by the baffle; one end of the refluxing chamber is separated; a channel communicating the front chamber with the rear chamber is kept between the baffle and the end surface of the refluxing chamber at the other end of the refluxing chamber,; an air outlet is arranged at the other end of the refluxing chamber far away from the channel and can be arranged to face to different directions. The ventilation structure greatly reduces the outer leakage of noise and diminishes the possibility of forced resonance of the housing; cold air blows from the air outlet to the housing of the generating set so as to carry out target-oriented cooling on the heating apparatus and parts on an air flow passing road, thus improving the cooling effect;; a zigzag air inlet channel is beneficial to maintain the cleaning of the inside of the generating set.

Description

A kind of aeration structure of quiet generator set

Technical field

The utility model relates to a kind of aeration structure of quiet generator set, and specifically a kind of formula aeration structure of quiet generator set belongs to air flows controlling component technical field.

Background technique

In prior art, traditional internal combustion engine generator group adopts the straight-through type suction port usually, promptly leaves air-inlet grille on housing, and cool air directly enters enclosure interior by air-inlet grille unit is cooled off.But straight-through type air-inlet grille is to the almost unseparated effect of the propagation of sound, and the running noise of internal-combustion engine can pass air-inlet grille to external radiant with not blocked, causes environmental pollution.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of aeration structure of quiet generator set, can cut off the generator set internal noise effectively to extraradial approach, reduce noise pollution, and can prevent that the sand and dust and the foreign material that suspend in the air from entering generator set inside.

Main solution of the present utility model is achieved in that

The utility model mainly comprises electric generator set casing body, air-inlet grille, refluxing chamber and sound-absorbing flush coat, refluxing chamber is arranged in the back side of electric generator set casing body, the gabarit of air-inlet grille is linked to each other with electric generator set casing body by refluxing chamber and partly surrounds, be provided with the dividing plate parallel in the refluxing chamber with electric generator set casing body, dividing plate is separated into refluxing chamber by area about equally, and former and later two chambers with a channel connection, exhaust outlet is located at the rear chamber of refluxing chamber, described passage pass through area and front and back chamber to pass through area suitable, described passage is located at refluxing chamber tunnel ends T and holds, and described exhaust outlet is located at refluxing chamber outlet air end P and holds.

For obtain cooling air different enter the flow direction, make cooling scheme have diversity, described exhaust outlet can be located at end face or at least one side of refluxing chamber outlet air end P end; Described refluxing chamber passage T end can exchange upper-lower position with described refluxing chamber outlet air end P end.Described refluxing chamber outlet air end P is positioned at the lower end of refluxing chamber.Described refluxing chamber outlet air end P is positioned at the upper end of refluxing chamber.

The inner and outer surface of described refluxing chamber is laid with the sound-absorbing flush coat respectively.

The internal surface of described refluxing chamber is laid with the sound-absorbing flush coat.

The outer surface of described refluxing chamber is laid with the sound-absorbing flush coat.

Compared with the prior art the utility model has the following advantages:

The utility model is simple, compact and reasonable for structure; Because refluxing chamber is configured to dioptric type multilayer screen structure with the housing position at place, has not only reduced leaking of noise widely, has also increased housing rigidity, has reduced the possibility that housing is forced to resonate; The air-out direction of refluxing chamber exhaust outlet has multiple choices, and the cool air that enters electric generator set casing body is cooled off targetedly to being positioned at the heater members that air communication crosses on the route selectively; Have the bigger temperature difference between cool air that cause newly enters and heater members, cooling effect is improved; Because air-flow is guided with zigzag path by refluxing chamber and enters electric generator set casing body inside, the most of sand and dust foreign material that contained in the air etc. are trapped in the refluxing chamber, help keeping the cleaning of unit inside; Laying of flexible cellular material can also absorb, shield a part of noise.

Embodiment

A kind of specific embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

The utility model mainly comprises electric generator set casing body 1, air-inlet grille 2, refluxing chamber 3, sound-absorbing flush coat 4, dividing plate 5, exhaust outlet 6, passage 7, refluxing chamber tunnel ends T, refluxing chamber outlet air end P.

The utility model adopts refluxing chamber 3 to be arranged in the back side of electric generator set casing body 1, and the gabarit of air-inlet grille 2 is linked to each other with electric generator set casing body 1 by refluxing chamber 3 and partly surrounds.In refluxing chamber 3, be provided with the dividing plate 5 parallel with electric generator set casing body 1, dividing plate 5 with refluxing chamber 3 be separated into by area about equally, former and later two chambers of being communicated with by passage 7, exhaust outlet 6 is located at the rear chamber of refluxing chamber 3, described passage 7 pass through area and front and back chamber to pass through area suitable, and be located at refluxing chamber tunnel ends T and hold, described exhaust outlet 6 is located at refluxing chamber outlet air end P and holds.

In the present embodiment, cooling air is guided by dividing plate 5 after entering the front chamber of refluxing chamber 3, and passage 7 places of chamber turn to and enter rear chamber before and after being communicated with, with the downward inflow generator group inside that flows to.

In order to take into account the smoothness that air communication crosses and to intercept the shielding of noise, the height of refluxing chamber central diaphragm should rationally be set, make passage 7 pass through area and forward and backward chamber to pass through area suitable, the too little circulating resistance that then increases too greatly then reduces soundproof effect.Consider the restriction loss that air communication is out-of-date, described air-inlet grille 2 pass through pass through the area of area greater than the passage 7 that is communicated with refluxing chamber 3 front and back chambers, both areas compare: air-inlet grille 2 pass through area/passage 7 pass through area=(1.1～1.8).

For the required cooling air of the different vent locations that adapt to required cooling scheme of different generator set or identical generator set to, exhaust outlet can also be arranged in different positions and direction, to satisfy various actual demand, is exemplified below:

Example 1: the exhaust outlet in the present embodiment 6 is changed into by Open Side Down: a. opening is (from housing outer surface, down together) backward; B. opening left; C. opening to the right; Or d. left and right sides opening.

Example 2: the refluxing chamber in the present embodiment 3 is turned into the T end holds in last attitude, make exhaust outlet 6 be in the top of refluxing chamber 3 at following, P.

Under the prerequisite that does not hinder charge flow rate, the inner and outer surface of described refluxing chamber 3 posts the sound-absorbing flush coat 4 that one deck is made by flexible cellular material, with shielding and absorption of noise.
