Embodiment
The present invention will be further described below in conjunction with concrete drawings and Examples.
As Fig. 1～shown in Figure 6, the present invention mainly is made up of top cover 1 and top cover connecting 2 two-part, the inside lower end of top cover 1 is provided with mounting plate 6, offer mounting hole 7 on the mounting plate 6, offer corresponding mounting hole on top cover connecting 2, top cover 1 and top cover connecting 2 utilize screw to be assemblied in generator set top.In top cover 1, be provided with dividing plate 10, dividing plate 10 is separated into separate refluxing chamber A and hot blast chamber B with top cover 1 inner chamber, on the sidewall of refluxing chamber A, offer and be used for the air-inlet grille 15 that cold air flows into, offer cold air outlet 12 on the top cover connecting 2 corresponding to refluxing chamber A, flow into the interior cold air of refluxing chamber A via in the cold air outlet 12 inflow generator groups; Offer the grid 9 of giving vent to anger that is used for the hot gas outflow on the sidewall of hot blast chamber B, offer hot air intake 3 on the top cover connecting 2 corresponding to hot blast chamber B, the hot gas in the generator set enters in the B of hot blast chamber via hot air intake 3; Described air-inlet grille 15 is arranged on the relative side of top cover 1 with the grid 12 of giving vent to anger, and can effectively prevent thermal cycle.
As Fig. 1, Fig. 4 and shown in Figure 5, the refluxing chamber A inwall at described air-inlet grille 15 places is provided with suction port baffle plate 14, suction port baffle plate 14 is the upslope structure of ecto-entad, the lowest surfaces that is air-inlet grille 15 is the minimum point of suction port baffle plate 14, after rainwater enters top cover 1 from air-inlet grille 15, major part is trapped within on the suction port baffle plate 14, the rainwater that is trapped on the suction port baffle plate 14 flows to low spot from the height point under action of gravity, at last outside air-inlet grille 15 is discharged to top cover 1, make the generator set that this top cover 1 is housed can prevent effectively that rainwater from entering unit inside when using out of doors, suction port baffle plate 14 also has certain soundproof effect simultaneously.Direction over against air inlet grid 15 in the refluxing chamber A is provided with air inlet dividing plate 11, air inlet dividing plate 11 is fixed on the crown center position of top cover 1, form air-flow port 16 between air inlet dividing plate 11 bottoms and the top cover connecting, cold air outlet 12 is opened on the top cover connecting 2 of air inlet dividing plate 11 opposite sides, and cold air passes air-flow port 16 after by in the cold air outlet 12 inflow generator groups.Air inlet dividing plate 11 in the refluxing chamber A can stop that the generator set interior noise to external radiation, effectively reduces noise pollution, improves soundproof effect; In general, air inlet dividing plate 11 is big more, soundproof effect is good more, but air inlet dividing plate 11 increases, air-flow port 16 will correspondingly reduce, air-flow port 16 reduces and can be to circulation causes resistance to cold air, influence heat radiation cooling effect, so, for taking into account air communication happy property of crossing and the shielding that intercepts noise, the present invention rationally is provided with air inlet dividing plate 11 height among the refluxing chamber A, the area that makes the area of air-flow port 16 be slightly larger than air-inlet grille 15, and promptly the ratio of the area of the area of air-inlet grille 15 and air-flow port 16 is controlled between 1: 1.1～1: 1.4.Though suction port baffle plate 14 can effectively stop rainwater to enter in the top cover 1, but when generator set is worked, still have water vapour in the top cover 1, having some water behind the generator set long-play accumulates in the refluxing chamber A, if these water are in cold air outlet 12 inflow generator groups, cause equipment to break down easily, so the present invention is being provided with a corral plate 13 on the upper-end surface around the cold air outlet 12, coaming plate 13 can prevent effectively that the water in the top cover 1 from flowing in the generator set of below.
As Fig. 1, Fig. 3 and shown in Figure 5, the hot blast chamber B inwall at described grid 9 places of giving vent to anger is provided with two air outlet baffle plates 8 up and down, air outlet baffle plate 8 also is the upslope structure of ecto-entad, it can prevent effectively that rainwater from entering unit inside and having certain soundproof effect, and concrete principle is identical with suction port baffle plate 14.The volume of described hot blast chamber B is greater than the volume of refluxing chamber A, because the horizontal span of top cover 1 is bigger, in order to guarantee the intensity of top cover 1, the present invention is provided with vertical top cover support plate 5 in the B of hot blast chamber.Be provided with the air-out guide plate 4 of inclination above the hot air intake 3 in the B of hot blast chamber, air-out guide plate 4 is used to guide hot gas to turn to, and increases so that enter the hot gas flow velocity of top cover hot blast chamber B, and kinetic energy rejection reduces, thereby utilize heat to distribute, improve cooling effectiveness.
As Fig. 1, Fig. 2 and shown in Figure 6, the top cover 1 among the present invention adopts steel plate punching press or bending to form, and the top of top cover 1 is middle high, the low pitched roof structure in both sides, can get rid of sleet timely when this structure can make the present invention use out of doors, prevents its accumulation.
During concrete the application, the cold air that plays cooling action flows in the refluxing chamber A from the air-inlet grille 15 on the top cover 1, pass the air-flow port 16 of air inlet dividing plate 11 bottoms then and enter generator set inside with cooling unit parts via cold air outlet 12, the heating component of cold air and unit inside carries out becoming hot gas after the heat exchange, this hot gas enters in the hot blast chamber B of top cover 1 from the hot air intake 3 on the hot blast chamber B of top cover 1 another side, 4 guiding turn to hot gas through the air-out guide plate, thereby have higher flow velocity and kinetic energy, be discharged to the unit outside from the grid 9 of giving vent to anger then.
The side at the air-inlet grille 15 and grid 9 places of giving vent to anger can be carried out conversion as the case may be among the present invention, to adapt to the outlet and inlet direction of different generator set.In addition, under the prerequisite of flow that does not hinder the gas turnover and kinetic energy, can post the sound-absorbing flush coat that one deck flexible cellular material is made on the internal surface of described refluxing chamber A and hot blast chamber B, the noise in order in shielding, the absorption unit further improves quiet effect.
