Embodiment 1
[0041] Example 1, such as image 3 , Figure 4 As shown, a double-channel variable-section volute device with guide vanes includes a volute 1, and the volute 1 is provided with a volute air inlet 11, a volute air outlet 12, and a volute air intake channel and Volute diffuser channel 2;
[0042] The volute air intake channel is provided with a pneumatic partition 13, and the aerodynamic partition 13 divides the volute air intake channel into the volute air intake inner channel 6 and the volute air intake outer channel 5;
[0043] The volute air intake outer flow channel 5 is located on the circumferential outer side of the volute air intake inner flow channel 6;
[0044] Vaneless nozzles 15 are respectively provided at the positions of the volute air intake outer flow channel 5 and the volute air intake inner flow channel 6 close to the volute diffuser passage 2;
[0045] A plurality of airfoil-shaped aerodynamic guide vanes 14 are evenly arranged in a circular shape near th...
Embodiment 2
[0059] Example 2, such as Figure 6 As shown, in order to be applicable to a pulse supercharging system, such as a six-cylinder engine, in the above-mentioned embodiment 1, the volute air inlet 11 can also be designed as a double air inlet: comprising the air inlet 24 on the left side of the volute and the volute Right air intake 25.
[0060] Such as Figure 7 As shown, the volute intake inner flow channel 6 is provided with a pulse inner flow channel rib 8, and the pulse inner flow channel rib 8 divides the volute intake inner flow channel 6 into the left pulse inner flow channel 9 And the inner runner 10 of the pulse on the right side.
[0061] The left pulse inner flow channel 9 and the right pulse inner flow channel 10 are respectively connected with the left air inlet 24 of the volute and the right air inlet 25 of the volute.
[0062] The cross-section of the pulse internal flow channel rib 8 is tapered, and the pulse internal flow channel rib 8 is connected with the p...
