Detailed Implementation

[0030] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0031] Please see Figures 1-8 This utility model provides a cooler outlet pipe, including an outlet pipe 100, which includes a pipe body 110. The upper end of the pipe body 110 is fixedly mounted with a mounting seat 111 for connection to the cooler outlet. The mounting seat 111 is bolted to the cooler outlet to allow exhaust gas to enter the pipe body 110. The lower end of the pipe body 110 is mounted with a mounting seat 112 for connection to a mixer. The mounting seat 112 is bolted to the mixer to allow gas to enter the mixer cavity and mix with the ambient air inside. The bottom outer wall of the pipe body 110 is machined with external threads 113.

[0032] The lower end of the exhaust pipe 100 is equipped with a gas mixing structure 200 to facilitate the mixing of exhaust gas and natural air. The gas mixing structure 200 is inserted into the inner cavity of the mixer. The gas mixing structure 200 includes an exhaust pipe 210, which includes a pipe body 211. The middle part of the pipe body 211 has multiple exhaust holes 212 for exhaust gas flow. The upper end of the pipe body 211 is fixedly installed with a funnel-shaped block 213. Multiple connecting blocks 214 are fixedly installed on the outer wall of the funnel-shaped block 213.

[0033] A guide ring 215 for guiding exhaust gas is fixedly installed inside the funnel-shaped block 213. The outer wall of the guide ring 215 is welded to the inner wall of the funnel-shaped block 213. The guide ring 215 includes a first arc-shaped end 10 and a second arc-shaped end 20 for guiding the gas. After the exhaust gas enters the second pipe 211, if the exhaust gas is conveyed upward, the exhaust gas is buffered under the guidance of the first arc-shaped end 10. Then the exhaust gas moves towards the second arc-shaped end 20. Since the exhaust gas is conveyed to the second outlet pipe 210 through the first pipe 110, the exhaust gas is conveyed into the second pipe 211 through the middle cavity of the guide ring 215. The exhaust gas at the second arc-shaped end 20 flows towards the middle of the guide ring 215 under the guidance of the second arc-shaped end 20 and is blown by the exhaust gas to continue to be conveyed into the second pipe 211. The guide ring 215 blocks the exhaust gas, preventing the exhaust gas from being conveyed to the upper end of the inner cavity of the funnel-shaped block 213.

[0034] The upper end of the second exhaust pipe 210 is equipped with a connecting cover 220 for limiting the second exhaust pipe 210 in conjunction with the first exhaust pipe 100. The connecting cover 220 includes a cover body 221. The middle part of the cover body 221 is provided with multiple air inlets 222 for allowing natural air to flow into the second exhaust pipe 211. Through the setting of the air inlets 222, the natural air in the mixer cavity can enter the upper cavity of the funnel-shaped block 213 through the multiple air inlets 222, and be initially mixed with the exhaust gas through the upper cavity of the funnel-shaped block 213.

[0035] A vent 223 is provided in the middle of the cover 221, through which vent gas flows into the pipe 211. The vent 223 and the middle hole of the guide ring 215 are concentric circles, and the diameter of the cavity of the vent 223 is smaller than the diameter of the cavity of the middle hole of the guide ring 215. Multiple connecting blocks 224 that fit against connecting block 214 are fixedly installed on the outer wall of the cover 221. Bolts 225 are installed in the middle of the connecting blocks 224 to facilitate the fixing of the vent pipe 210 and the connecting cover 220. A connecting pipe 226 is fixedly installed at the upper middle part of the cover 221. The internal thread 227 of the connecting pipe 226 is machined to connect with the external thread 113. When the gas mixing structure 200 is installed on the gas outlet pipe 100, the bottom of the pipe body 110 is inserted into the connecting pipe 226. By rotating the cover 221, the connecting pipe 226 is rotated synchronously, so that the internal thread 227 and the external thread 113 are threadedly connected, and finally the cover 221 is fixed to the bottom end of the pipe body 110. Then, the gas outlet pipe 210 is installed at the lower end of the connecting cover 220, so that the connecting block 224 and the connecting block 1 214 are in contact. The funnel-shaped block 213 is fixed to the lower end of the cover 221 by bolts 225, and the gas outlet pipe 210 can be fixed to the lower end of the connecting cover 220.

[0036] A guide 230 for guiding exhaust gas is installed inside the exhaust port 212. The guide 230 includes a V-shaped block 231, which is inserted into the exhaust port 212. Exhaust ports 232 for gas flow are opened on both sides of the V-shaped block 231. The exhaust ports 232 on both sides of the V-shaped block 231 are staggered to facilitate the mixing of exhaust gas and natural air and avoid excessive concentration of exhaust gas. Connecting blocks 233 are fixedly installed at both the upper and lower ends of the V-shaped block 231. The connecting blocks 233 are welded to the outside of the cavity of the exhaust port 212, so that the V-shaped block 231 separates the cavity of the exhaust port 212 when it is inside the exhaust port 212.

[0037] The exhaust gas in the cooler is transported to the interior of the exhaust pipe 210 through the pipe body 110 and the exhaust gas hole 223. The exhaust gas is transported to the inner cavity of the pipe body 211 through the middle hole of the guide ring 215. Part of the exhaust gas is discharged through the gap between the V-shaped block 231 and the exhaust hole 212 and mixed with natural air. Another part of the exhaust gas is discharged through the exhaust hole 232 and mixed with natural air. This utility model can increase the mixing efficiency of exhaust gas and natural air in the mixer by cooperating with multiple exhaust holes 212 and guide members 230. Moreover, the setting of multiple air inlets 222 facilitates the entry of natural air into the upper cavity of the funnel-shaped block 213 and mixed with the exhaust gas.

[0038] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
