Problems solved by technology

[0003] Since the cross-section of the fan case 200 is a cuboid structure, and the heat exchanger 300 is installed vertically, there is a problem in this structure: The area forms a spiral flow, and the wind blown by the blower 100 will not directly reach the heat exchanger 300 at the air outlet of the volute, and peeling will occur, which will affect the efficiency of the fan

Abstract

The invention discloses a coiled pipe blower structure. The coiled pipe blower structure comprises a blower, a blower box body and a heat exchanger, wherein the blower comprises a volute, a wind wheel and a motor; the wind wheel is mounted in a first cavity of the volute; the volute is provided with a first air inlet and a first air outlet; an output shaft of the motor extends into the first cavity and is connected with the wind wheel; the blower box body is provided with a second cavity; a second air inlet is arranged on one side of the blower box body, and a second air outlet is arranged on the other side of the blower box body; and the heat exchanger is mounted in the second cavity and positioned between the second air inlet and the second air outlet. The coiled pipe blower structure is characterized in that the volute tongue part of the first air outlet of the volute is connected with a static pressure return plate, the static pressure return plate is obliquely arranged, the high end of the static pressure return plate is connected with the volute tongue at the air outlet of the volute, and the low end of the static pressure return plate extends towards the heat exchanger. The coiled pipe blower structure can effectively improve the running efficiency of the blower, reduce consumption and save electricity energy.
