Double-layer flow blower and automobile air conditioner

Abstract

The application relates to the technical field of automobile air conditioners, and particularly discloses a double-layer flow blower, which comprises a shell, an impeller assembly arranged in the shell, a volute arranged in the shell, a partition plate arranged in the volute, an installation space in the volute being divided into an upper flow space and a lower flow space by the partition plate, the impeller assembly being rotatably arranged in the volute and penetrating through the partition plate, an anti-air-leakage boss being arranged at the outer edge of the impeller assembly, and the end of the anti-air-leakage boss being higher than the end surface of the partition plate, so that when the impeller assembly slightly moves downward or upward, the gas blown in the radial direction also cannot exceed the partition plate, air leakage is caused through the gap a between the anti-air-leakage boss and the partition plate, heat loss and energy consumption are reduced, and the vehicle window is free of fogging while the heating effect is met. The application further provides an automobile air conditioner comprising the double-layer flow blower.
