Accompanying drawing explanation
Fig. 1 shows the shell schematic diagram of the utility model embodiment's diesel generating set.
Embodiment
Below by specific embodiment, also by reference to the accompanying drawings the utility model is described in further detail.
Be illustrated in figure 1 a kind of diesel generating set that the present embodiment provides, comprise that side is provided with the shell 101 of a plurality of intake grills and a plurality of exhaust outlets; The bottom of shell 101 is provided with for the sump of diesel engine being carried out to the first cooling intake grill; The top of shell is provided with the first exhaust outlet.
The diesel generating set that the utility model embodiment provides, compared with prior art, this diesel generating set, except a plurality of intake grills and a plurality of exhaust outlet of side, is also included in the first exhaust outlet that the top of shell arranges and the first intake grill of bottom.When ambient temperature surpasses 55 ℃, cold wind enters from the first intake grill of outer casing bottom, thereby carry out cooling to the sump of diesel engine, wherein the machine oil of sump inside is except lubricating function, also have cooling heat dissipation function, cooling to sump of cold wind, makes machine oil in sump in good ventilation heat dissipation environment, thereby make machine oil keep good cooling heat dissipation function, and then reduce the temperature of each equipment in diesel generating set.In addition, cold wind enters and a plurality of intake grills of side enter from the first intake grill of bottom, first exhaust outlet at exhaust outlet that can also be from the side and top is discharged, thereby increased the heat dissipation channel in shell, and then the temperature in reduction shell, avoid excess Temperature to cause diesel generating set normally not move.
Preferably, the first exhaust outlet is also positioned at the position of cylinder of diesel engine top.Particularly, cold wind is from the first intake grill of bottom enters in diesel generating set, and cold wind within it portion forms a plurality of cooling channels.A plurality of cooling channels can be communicated with a plurality of exhaust ports.First exhaust outlet of the present embodiment is preferably placed at the top of cylinder of diesel engine, to have considered that in diesel engine running, cylinder can produce a large amount of heats, the first exhaust outlet is arranged on to the top of cylinder of diesel engine, the amount of heat that cylinder produces can and then be taken away by cylinder in cooling channel, avoid heat in diesel generating set inner accumulated, further reduce the temperature in shell.
Preferably, a plurality of intake grills are two, and it comprises the second intake grill 102 and the 3rd intake grill 106; A plurality of exhaust outlets comprise the second exhaust outlet 105 and the 3rd exhaust outlet 104.Certainly, a plurality of intake grill can also comprise three, four or more.
Preferably, the second intake grill 102 is positioned at the left side of shell 101; The 3rd intake grill 106 is positioned at the positive lower left quarter of shell 101.
Preferably, the second exhaust outlet 105 is positioned at the positive middle and upper part of shell 101; The 3rd exhaust outlet 104 is positioned at the positive upper right quarter of shell 101.Wherein, the density of the density ratio cold wind of hot blast is low, cold wind can be from left side and bottom enter, then from top, discharge, avoid the hot blast of discharging again from intake grill, to enter.
Preferably, on the first exhaust outlet, be provided with rain-proof shed 103.For fear of dust or rainwater, from the first exhaust outlet, enter in diesel generating set, this rain-proof shed 103 is positioned on the first exhaust outlet.
It should be noted that, the diesel generating set of the present embodiment is through Analysis of overheat simulation analysis, when ambient temperature is 55 ℃, diesel engine radiation heating value is 4.8KW, and generator heat-radiation amount is 1.54KW, analyzes and shows that high-temperature temperature district is positioned near smoke evacuation assembly, temperature is 72.6 ℃, diesel engine upper temp is also higher, and near the close smoke evacuation of upper exhaust port assembly, temperature can reach 76.3 degrees Celsius, and these local temperatures can not have influence on the normal operation of power station under hot environment.The result obtaining in conjunction with fluid field analysis can obtain, and the position of bottom intake grill is not only taken away the heat of diesel engine bottom, and the hot air simultaneously generator being shed is discharged from the exhaust outlet of sidewall.
In addition, the diesel generating set of the present embodiment except normally moving when ambient temperature surpasses 55 ℃, also well coordinated the relation of heat radiation and noise, total institute is known, the opening of the shell of diesel generating set is more, its noise radiating can be larger, excessive for fear of noise, and existing diesel generating set arranges two intake grills and two exhaust outlets conventionally in side.And the diesel generating set of the present embodiment is also provided with the first intake grill and the first exhaust outlet at top and bottom, wherein the first intake grill is used for into cold wind, only have noise seldom to propagate out from the first intake grill, and the noise of propagating out can run into ground and then propagate into the end, ground, the noise that the first intake grill is transmitted in surrounding environment is very low.In addition, the noise of propagating out from the first exhaust outlet can run into rain-proof shed stopping and reflect, and noise can be subdued a part, and the noise that makes to be transmitted in surrounding environment weakens.Preferably, at rain-proof shed inwall, can be provided with noise reduction layer, further reduce noise.The diesel generating set noise that is the present embodiment is low.
These are only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
