Heteroaxial bidirectional ventilation structure

Abstract

The invention discloses a heteroaxial bidirectional ventilation structure which comprises an air duct extending along the vertical direction, an inlet structure and an outlet structure, wherein one end of the air duct is an air inlet, and the other end of the air duct is an air outlet; the inlet structure comprises an inlet motor and an inlet impeller, the inlet motor is relatively fixed to the air duct, the inlet motor is in driving connection with the inlet impeller, the inlet impeller is located at the air inlet, and the inlet impeller is provided with a plurality of inlet blades circumferentially arrayed along the rotating axis of the inlet impeller; the outlet structure comprises an outlet motor and an outlet impeller, the outlet motor is relatively fixed on the air duct, the outlet motor is in driving connection with the outlet impeller, the outlet impeller is located at the air outlet, the rotation axis of the outlet impeller and the rotation axis of the inlet impeller are collinear, and the rotation direction of the outlet impeller is opposite to the rotation direction of the inlet impeller; the outlet impeller is provided with a plurality of outlet blades circumferentially arrayed along the rotation axis of the outlet impeller; and according to the heteroaxial bidirectional ventilation structure, the ventilation requirement can be met at the low rotation speed, the total-pressure efficiency is greatly improved, and noise and energy consumption are reduced.

Description

technical field [0001] The invention relates to a ventilation structure, in particular to an off-axis two-way ventilation structure. Background technique [0002] In different scenarios such as industry, it is often necessary to use ventilation and heat dissipation structures, such as cooling towers. An impeller is usually installed inside the existing cooling tower, and the impeller is used to work to achieve the effect of ventilation and heat dissipation. To improve the ventilation and heat dissipation effect, generally It is to increase the speed of the impeller, but the higher the speed, the higher the noise, and the corresponding increase in energy consumption. There are some cooling towers on the market with multiple impellers arranged horizontally inside, which can reduce the speed of the impeller while providing the same air volume. However, the reduction in total noise and total energy consumption is small, and the optimization effect is minimal. Contents of the i...
