Abstract
The invention relates to a bedplate structure of a silent generator set, in particular to a bedplate of a focused air-intake internal combustion energy generator set, belonging to the ventilation technical field of air circulation, which is characterized in that an air inlet is arranged on one end of the bedplate; two flow focusing chambers are arranged on two sides of the end part of the bedplate; two opposite air outlets are respectively arranged on the two flow focusing chambers; the section of an air flow channel of the air inlet is arranged approximately vertically to the horizontal plane. With simple, compact and reasonable structure, the invention has the advantages that the focused air-intake method enables the cooled airflow to enter the bedplate from one end of the generator set with high speed and dynamic energy so that the heat exchange rate between the cooled air and the surfaces of hot units is enhanced; and the appropriate air inlet arrangement ensures smooth airflow inside the enclosed cabinets of the whole generator set.
Description
Technical field
The present invention relates to a kind of chassis structure of quiet generating set, the chassis of conflux air admission type internal combustion engine generator group specifically belongs to the aeration technology field of air circulation.
Background technology
Traditional closed internal combustion engine generator group chassis, air inlet dispersed placement each orientation on the chassis, some is arranged in the bottom on chassis usually, and some is arranged in the periphery on chassis.This dispersed placement; usually can make and take place mutually between the air-flow to disturb even head-on collision because of the direction difference of air inlet; consumed the air-flow self kinetic energy, therefore behind expanded by heating, more early risen to the top of case, can not cool off engine and generator fully.
In addition, section bar manufacturings such as channel-section steel, angle steel are usually adopted on traditional generating set chassis in a large number, cause the chassis too heavy.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of chassis structure of quiet generating set is provided, can keep air-flow to have bigger kinetic energy and more consistent flow direction, and can cool off fully engine and generator.
Main solution of the present invention is achieved in that
The present invention mainly comprises chassis, air inlet, it is characterized in that air inlet is arranged on an end on chassis, is furnished with two conflux chambers in the end, chassis with interior both sides.
Be respectively equipped with air stream outlet in opposite directions on described two conflux chambers.
The gas channel cross section of described air inlet is perpendicular to horizontal plane.
Described chassis adopts steel stamping part or bending part to constitute.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Because the conflux intake method is adopted on the chassis, make cooling blast enter the chassis from an end of generating set, has higher flow velocity and kinetic energy, high velocity air skims over the engine sump tank surface, can increase heat transfer rate between the two, obtain better cooling effect, simultaneously, in flow process expanded by heating air also rise naturally, taken into account the cooling of other heating position in the unit.Owing to reasonably set the air inlet arrangement, made that the air flows in the generating set sealing rack is unobstructed.The airflow field that passes through rack distributes the rack temperature inside to be rendered as the inlet end temperature low, and the situation that the outlet side temperature is high is very favourable to arranging parts such as control unit, generator, engine and muffler successively.
Description of drawings
Fig. 1 is a schematic perspective view of the present invention.
Fig. 2 is the flow direction schematic diagram of the present invention's steering current when the generating set assembly assembles.
Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
Fig. 1, shown in Figure 2: it is mainly by chassis 1, air inlet 2, and conflux chamber 3, generator 4, Power generator fan 41, engine 5, engine blower 51, engine sump tank 52, generating set front end F forms.
The present invention mainly comprises chassis 1, air inlet 2 and two conflux chambers 3.Air inlet 2 is arranged on an end on chassis 1, and 1 end is furnished with two conflux chambers 3 (this end is positioned at generating set front end F one side) with interior both sides on the chassis.Be respectively equipped with air stream outlet in opposite directions on described two conflux chambers 3.The gas channel cross section of described air inlet 2 is big extremely perpendicular to horizontal plane.
Operation principle of the present invention:
The cooling fan of engine 51 of the launched machine 5 of cold air aspirates, flow into the unit bottom through air inlet 2 with horizontal direction, the air current A that flows into from air inlet 2 middle parts wherein, because runner is unobstructed accessible, flow velocity is the fastest, be able to blow to engine sump tank 52 by generator 4 bottoms fast, it is cooled off.And the air-flow B that enters from air inlet 2 both sides owing to be subjected to the guiding of conflux chamber 3, changes the flow direction via 3 outlets of conflux chamber to import the middle part air-flow, has more increased the kinetic energy of middle part air-flow.Except that above-mentioned air guide function, the task of the supporting member that carries electric generator structure weight is also being undertaken in conflux chamber 3.
The generator 4 housing bottoms that are being connected with flywheel shell of engine, have a ventilation hole 42, this ventilation hole 42 is interior that contained, relative with Power generator fan 41 positions of the coaxial rotation of generator amature with housing, Power generator fan 41 is discharged the air in the generator housing by force through ventilation hole 42, make the air pressure of generator 4 inside be lower than its casing air outside pressure, under the effect of this pressure reduction, part air-flow is inhaled into from the end of generator 4 near air inlet 2, flow through the space between stator and the rotor, cooling effect has been played in generator 4 inside.
For weight reduction, all structural members on chassis 1 all adopt steel plate punching press or bending to make, and have both guaranteed its bearing capacity, have reduced material consumption again.
