Fig. 2 is a schematic view of the structure with the damper cover 100 and the wind scooper 200 removed from the generator set 010. Referring to fig. 1 and 2, in the present embodiment, the generator set 010 includes an air guiding structure 020, a muffler 300, an exhaust pipe 400, an engine 500, a motor 600, and a fan 700.
The exhaust pipe 400 includes a left cylinder exhaust pipe 410 and a right cylinder exhaust pipe 420.

The motor 600 is disposed in parallel with the muffler 300 and is in driving connection with the engine 500. The motor 600 is used to generate electricity under the drive of the engine 500. The cooling wind of the motor 600 is discharged through the gap between the muffler 300 and the engine 500.
The air guiding structure 020 will be described below. Fig. 3 is a schematic overall structure of an air guiding structure 020 according to this embodiment. Fig. 4 is a schematic diagram of a split structure of an air guiding structure 020 according to the present embodiment. It should be noted that, to more clearly illustrate the working principle of the air guiding structure 020, the muffler 300 and the exhaust pipe 400 are added in fig. 3 and 4. Referring to fig. 1 and 2, in the present embodiment, the wind guiding structure 020 includes a muffler cover 100 and a wind guiding cover 200.
The muffler cover 100 has a substantially rectangular structure. The muffler cover 100 includes a muffler front cover 110, a muffler left cover 120, a muffler right cover 130, and a muffler side cover 140. The muffler left cover 120 and the muffler right cover 130 are disposed opposite to each other and are connected to each other to form a cylindrical structure extending in the front-rear direction and define the accommodating cavity 101. The muffler 300 is accommodated in the accommodating cavity 101. The muffler front cover 110 is connected to the front ends of the muffler left cover 120 and the muffler right cover 130, and the muffler front cover 110 is provided with an air outlet 111. The muffler side cover 140 is provided at the rear end of the muffler left cover 120 to face the cooling wind of the motor 600. In the present embodiment, the muffler side cover 140 is provided with the air guide side wall 141 inclined with respect to the muffler left cover 120, and when the cooling air of the motor 600 is blown toward the muffler side cover 140, the air guide side wall 141 can guide the cooling air of the motor 600 to flow from the rear to the front toward the muffler front cover 110, so that the cooling air of the motor 600 can be used to cool the muffler 300.
The hood 200 includes an outlet 201 at a front end and an inlet 202 at a rear end. The outlet 201 of the air guide housing 200 is connected to the upper portion of the muffler right cover 130 of the muffler housing 100 such that the outlet 201 of the air guide housing 200 communicates with the accommodating cavity 101. The inlet 202 of the muffler cover 100 is opposite to the left cylinder air outlet 511 and the right cylinder air outlet 521 for introducing cooling air of the engine 500 into the muffler cover 100. The left cylinder exhaust pipe 410 and the right cylinder exhaust pipe 420 are accommodated in the hood 200.
Fig. 5 is a schematic perspective view of the wind scooper 200 according to the present embodiment. Fig. 6 is a schematic rear view of the wind scooper 200 according to the present embodiment. Referring to fig. 5 and 6, a guiding mechanism 210 is further disposed in the wind scooper 200. The air guiding mechanism 210 is used for guiding the cooling air received by the inlet 202 of the air guiding cover 200 to the outlet 201 of the air guiding cover 200. In this way, the cooling air is caused to enter the muffler cover 100 and flow from the rear to the front along the gap between the muffler cover 100 and the muffler 300, and finally is discharged from the air outlet 111 opened in the muffler front cover 110.
In this way, after cooling air of engine 500 flows out from left cylinder air outlet 511 and right cylinder air outlet 521, it directly enters air guide cover 200 through inlet 202 of air guide cover 200, then enters muffler cover 100 through outlet 201 of air guide cover 200, and finally is discharged through air outlet 111 opened in muffler front cover 110. Since the cooling air of the engine 500 flows out from the left cylinder air outlet 511 and the right cylinder air outlet 521 and is collected by the air guide cover 200, the cooling air flowing out from the left cylinder air outlet 511 and the right cylinder air outlet 521 is prevented from being blown to the panel back cover (not shown) of the generator set 010, and the panel back cover temperature of the generator set 010 is prevented from being excessively high. In addition, the excessive temperature of the portion of the oil tank (not shown) of the generator set 010 adjacent to the rear cover of the panel is avoided. Further, the cooling air flowing out from the left cylinder air outlet 511 and the right cylinder air outlet 521 cannot be blown to the bottom of the oil tank and the top of the motor 600, thereby avoiding the surface temperature of the motor 600 and the bottom temperature of the oil tank from being too high. Therefore, the temperature of the whole machine of the generator set 010 can be reduced, and the reduction of the performance and potential safety hazard of the whole machine caused by overhigh temperature of the generator set 010 can be avoided. In addition, the cooling air in the air guide cover 200 flows from the inlet 202 of the air guide cover 200 to the outlet 201 of the air guide cover 200 under the guidance of the air guide mechanism 210. In this process, the cooling wind can cool down the left cylinder exhaust pipe 410 and the right cylinder exhaust pipe 420. After the cooling air enters the muffler cover 100, the cooling air flows forward from behind along the gap between the muffler cover 100 and the muffler 300, and finally is discharged from the air outlet 111 opened in the muffler front cover 110. During this process, the cooling wind can cool down muffler 300. In this way, the full use of the cooling air is realized.
Experiments show that after the generator set without the air guide structure 020 is operated for 30 minutes at full load, the bottom temperature of the oil tank is 85 ℃, the shell temperature of the motor 600 is 150 ℃, the temperature of the rear panel cover of the generator set is 115 ℃, and the temperature of the part of the oil tank adjacent to the rear panel cover is 95 ℃.
In the generator set 010 with the air guiding structure 020 provided in this embodiment, after the generator set 010 works for 30 minutes at full load, the bottom temperature of the oil tank is 48 ℃, the shell temperature of the motor 600 is 86 ℃, the temperature of the rear cover of the panel of the generator set 010 is 80 ℃, and the temperature of the part of the oil tank adjacent to the rear cover of the panel is 49 ℃.
Further, referring to fig. 5 and 6, in the present embodiment, the air guiding cover 200 includes a top wall 220, a front side wall 230 extending downward from the edge of the top wall 220, a left side wall 240 and a right side wall 250; the left side wall 240 and the right side wall 250 are disposed opposite. The top wall 220, left side wall 240, and right side wall 250 collectively define the inlet 202 of the cowl 200; inlet 202 of cowl 200 is opposite front sidewall 230. The lower end of the front side wall 230 is recessed toward the top wall 220 to form the outlet 201 of the hood 200.
Further, in the present embodiment, the distance between the front sidewall 230 and the inlet 202 of the wind scooper 200 gradually increases in the top-to-bottom direction. In this way, the front side wall 230 can act as a guide. Cooling air is blown directly toward the front side wall 230 after entering the hood 200 through the inlet 202. Since the distance between the front sidewall 230 and the inlet 202 of the wind scooper 200 is gradually increased in the top-down direction, the cooling wind blown toward the front sidewall 230 can move downward under the guide of the front sidewall 230 and then flow out of the outlet 201. Thus, the flow velocity loss of the cooling air can be reduced, the cooling air can flow at a high speed, and the cooling capacity can be improved.
Further, in the present embodiment, the air guiding mechanism 210 extends downward from the inner surface of the top wall 220 along the front side wall 230, so as to divide the inner space of the air guiding cover 200 into a left air collecting space 200a near the left side wall 240 and a right air collecting space 200b near the right side wall 250; the left plenum 200a is for accommodating a left cylinder exhaust pipe 410 of the engine 500. The right plenum 200b is for accommodating a right cylinder exhaust pipe 420 of the engine 500. The outlet 201 of the wind scooper 200 is located below the left wind collecting space 200a. The air guiding mechanism 210 is used for guiding the cooling air in the left air collecting space 200a to the outlet 201 of the air guiding cover 200, and guiding the cooling air in the right air collecting space 200b to the outlet 201 of the air guiding cover 200. The inner space of the wind scooper 200 is divided into a left wind collecting space 200a near the left side wall 240 and a right wind collecting space 200b near the right side wall 250 by the wind guiding mechanism 210, wherein the left wind collecting space 200a is opposite to the left cylinder air outlet 511, the cooling wind flowing out from the left cylinder air outlet 511 enters the left wind collecting space 200a, the right wind collecting space 200b is opposite to the right cylinder air outlet 521, and the cooling wind flowing out from the right cylinder air outlet 521 enters the right wind collecting space 200b. In this way, the cooling air flowing out of the left cylinder air outlet 511 and the right cylinder air outlet 521 can be prevented from interfering with each other to form turbulent flow, and the reduction of the overall flow velocity of the cooling air in the air guide cover 200 caused by the mixing of the cooling air flowing out of the left cylinder air outlet 511 and the right cylinder air outlet 521 is avoided, so that the cooling air can maintain a higher flow velocity in the air guide cover 200, and further the left cylinder exhaust pipe 410 and the right cylinder exhaust pipe 420 can be cooled more efficiently. In addition, the flow direction of the cooling air in the air guide cover 200 can be more regular, so that the leakage amount of the cooling air from the air guide cover 200 to the outside is reduced.
Fig. 7 is a bottom view of the air guiding cover 200 in this embodiment. Referring to fig. 7, in the present embodiment, the flow guiding mechanism 210 includes a left flow guiding plate 211; the left baffle 211 extends downwardly from the inner surface of the top wall 220 along the front side wall 230; the distance from the left baffle 211 to the left sidewall 240 gradually increases in the top-to-bottom direction. The left baffle 211 and the left sidewall 240 together define a left wind collecting space 200a. Because the distance between the left baffle 211 and the left side wall 240 is gradually increased along the direction from top to bottom, the left baffle 211 and the left side wall 240 can better perform a guiding function, and further more effectively guide the cooling air in the left air collecting space 200a to the outlet 201 of the air guiding cover 200.
Further, in the present embodiment, the left air deflector 211 is bent toward the left side wall 240 from the side of the front side wall 230 to form a left air deflector 211a. The left wind guard 211a can prevent the cooling air in the left air collection space 200a from flowing back to the left cylinder air outlet 511. Correspondingly, the rear end of the left side wall 240 and the rear end of the top wall 220 near the left side wall 240 are also bent to the left air collecting space 200a to form a first return air blocking surface 260, so that the cooling air in the left air collecting space 200a is further prevented from flowing back to the left cylinder air outlet 511.
In this embodiment, the baffle mechanism 210 further includes a right baffle 212. The right baffle 212 extends downwardly from the inner surface of the top wall 220 along the front side wall 230. The distance from the right baffle 212 to the right sidewall 250 increases gradually in the top-to-bottom direction. The right baffle 212 and the right sidewall 250 together define a right plenum 200b. Since the distance between the baffle 212 and the right side wall 250 increases gradually along the direction from top to bottom, the right baffle 212 and the right side wall 250 can better perform guiding function, and further more effectively guide the cooling air in the right air collecting space 200b to the outlet 201 of the air guiding cover 200.
Further, in the present embodiment, a side of the right deflector 212 away from the front sidewall 230 is bent toward the right sidewall 250 to form the right wind deflector 212a. The right wind deflector 212a can prevent the cooling air in the right air collecting space 200b from flowing back to the right cylinder air outlet 521. Correspondingly, the part of the lower end of the front side wall 230, which is close to the right side wall 250, is bent backwards to form a second air return blocking surface 270, so that the cooling air in the right air collecting space 200b is prevented from flowing downwards out of the air guide cover 200.
Further, in the present embodiment, the distance between the right wind deflector 212a and the front side wall 230 is gradually reduced in the right-to-left direction, so that the flow rate of the cooling wind flowing from the right wind collecting space 200b to the outlet 201 of the wind scooper 200 can be increased, so that the cooling wind in the right wind collecting space 200b can flow into the outlet 201 of the wind scooper 200 more efficiently.
In summary, according to the air guide structure and the generator set provided by the embodiment of the invention, the cooling air of the engine is collected through the air guide cover, so that the cooling air of the engine is prevented from blowing to the panel back cover, the motor and the oil tank, the temperatures of the panel back cover, the motor and the oil tank are further reduced, and the overall performance and the safety of the generator set are improved. The cooling air of the engine entering the wind scooper from the inlet flows to the outlet of the wind scooper under the guidance of the flow guiding mechanism, and the exhaust pipe can be cooled in the flowing process. Cooling air of the engine flows out from an outlet of the air guide cover and then enters the muffler cover, so that the muffler is cooled. Thus, the cooling air of the engine is fully utilized.
