Abstract
The invention discloses a structure for cooling an engine silencer. The structure comprises an engine, a front half fan volute, a rear half fan volute and an impeller. The structure is characterized in that an induced air hole is arranged on the front half fan volute near the silencer and a wind shield is arranged on an inner wall of the front half fan volute positioned on one side of the induced air hole. The structure has the advantages that high-speed air flow flowing through a positive pressure area of a fan volute is blocked through the wind shield so that the high-speed air flow blows out through the induced air hole to cool the upper half part of the silencer, a lower wind shield blocks the high-speed air flow flowing through the positive pressure area of the fan volute so as to enable the high-speed air flow to blow out through a lower induced air hole to cool the lower half part of the silencer, the silencer can be cooled rapidly, temperature of the silencer is lowered, so that temperature of the whole engine is greatly reduced, and service life of the engine is greatly prolonged.
Description
Technical field
Patent of the present invention relates to technical field of engines, particularly a kind of structure of cooled engine.
Background technique
At present, containing catalyzer in China's emission regulation demands low emission level engine baffler, make full combustion of fuel when catalyzer is fissioned thus greatly reduce a large amount of harmful components contained in tail gas, alleviate the pollution of air, but, can produce during burning amount of heat cause baffler so that motor complete machine temperature too high, if lowered the temperature not in time, core component wearing and tearing are very fast, thus seriously reduce service life of aeroengine, take the mode of motor small fan cooling itself at present more, the effect of the cooling in time but a lot of motors can not be satisfied the demand, therefore, be badly in need of the structure of the quick cooled engine baffler of a kind of energy.
Summary of the invention
The object of this invention is to provide a kind of structure cooling low emission level engine baffler, this kind of motor is arranged on knapsack sprayer-duster, wind-driven cleaning machine etc. and utilizes on the portable machine of blower fan work, the high velocity air of drawing from the zone of positive pressure of volute of blower is utilized to cool baffler, this structure can reduce the temperature of baffler quickly and effectively, greatly improve the working life of motor, meet the requirement of low emission level engine.
The technological scheme that the present invention takes is:
A kind of structure of cooled engine baffler, comprise motor, first half volute of blower, later half volute of blower, impeller, described motor is provided with baffler, described impeller is placed in the snail road of forward and backward half volute of blower formation, motor is connected with impeller, motor is positioned at the side of first half volute of blower, it is characterized in that: the first half volute of blower near described baffler is provided with air inducing hole, and the first half volute of blower inwall of side, air inducing hole is provided with barge board.
Described air inducing hole is provided with air inducing hole and lower air inducing hole, and upper air inducing hole is positioned at baffler adjacent upper part, and lower air inducing hole is positioned at baffler adjacent bottom portions.
Described barge board is provided with barge board and lower barge board, and described upper barge board is positioned at the side in air inducing hole, and described lower barge board is positioned at the side in lower air inducing hole.
Described upper air inducing hole and lower air inducing hole are multiple.
The invention has the beneficial effects as follows, the part high velocity air flowing through volute of blower zone of positive pressure blocks by upper barge board, make high velocity air from the upper air inducing hole blowout cooling baffler first half, the part high velocity air flowing through volute of blower zone of positive pressure blocks by lower barge board, make high velocity air from lower air inducing hole blowout cooling baffler Lower Half, baffler can be cooled rapidly, and temperature is reduced, thus greatly reduce motor complete machine temperature, improve service life of aeroengine greatly.

In accompanying drawing, sequence number illustrates: 1, motor; 2, impeller; 3, first half volute of blower; 4, fastening screw trip bolt; 5, later half volute of blower; 6, upper air inducing hole; 7, baffler; 8, lower air inducing hole; 9, snail road; 10, upper barge board; 11, lower barge board.
Embodiment
As shown in Figure 1, Figure 2, Fig. 3, Fig. 4, shown in accompanying drawing 5, the present invention program is made up of motor 1 (baffler 7), first half volute of blower 3 (upper air inducing hole 6, lower air inducing hole 8, snail road 9, upper barge board 10, lower barge board 11), later half volute of blower 5, impeller 2.
Impeller 2 is placed on 9 li, the snail road that first half volute of blower 3 and later half volute of blower 5 are combined to form, and first half volute of blower 3 and later half volute of blower 5 are connect by fastening screw trip bolt 4, and impeller 2 is connected with motor 1.
Upper air inducing hole 6, lower air inducing hole 8, upper barge board 10, lower barge board 11 are all on first half volute of blower 3, upper air inducing hole 6, lower air inducing hole 8 are multiple, upper air inducing hole 6 is positioned at the position that first half volute of blower 3 is close with baffler 7 upper half part, and lower air inducing hole 8 is positioned at the position that first half volute of blower 3 is close with baffler 7 lower half portion.Upper barge board 10 is positioned on the inwall of first half volute of blower 3, and is positioned at the below in air inducing hole 6, and lower barge board 11 is positioned on the inwall of first half volute of blower 3, and is positioned at the below in lower air inducing hole 8.
1 impeller 2 of piloting engine High Rotation Speed in the snail road 9 that first half volute of blower 3 and later half volute of blower 5 are formed produces high velocity air, high velocity air flows along certain direction in snail road, when high velocity air flows through upper barge board 10 by upper air inducing hole 6, upper barge board 10 stop portions high velocity air makes it the upper half part blowing to baffler 7 through the ejection of upper air inducing hole 6; When high velocity air flows through lower barge board 11 by lower air inducing hole 8, lower barge board 11 stop portions high velocity air makes it the lower half portion blowing to baffler 7 through the ejection of lower air inducing hole 8, rapidly cooling baffler 7.
The invention has the beneficial effects as follows, being blocked by the high velocity air flowing through volute of blower zone of positive pressure through upper barge board makes it through the upper air inducing hole blowout cooling baffler first half, the high velocity air flowing through volute of blower zone of positive pressure blocks and makes it through lower air inducing hole blowout cooling baffler Lower Half by lower barge board, baffler can be cooled rapidly, temperature is reduced, thus greatly reduce motor complete machine temperature, improve the working life of motor greatly.
