The invention relates to the technical field of double-layer motor car ventilation, and discloses a confluence special-shaped air duct structure. Comprising a main air duct, an air outlet is formed in the front side of the main air duct, an end flange is arranged at the end of the air outlet, and an air supply mechanism is arranged on the rear side of the main air duct and used for conveying air; the air supply mechanism comprises two symmetrically-arranged air supply pipes connected to the rear side of the main air duct in a penetrating mode, air inlets are formed in the ends of the air supply pipes, connector flanges are arranged at the air inlets, and the main air duct and the air supply pipes can be fixed to the corresponding air ducts through bolts at the connector flanges and the end flanges. Wherein the cross section of the top face of the main air duct is in a V shape, the air supply pipe is obliquely arranged on the rear side of the main air duct, and the inclination angle between the air supply pipe and the main air duct ranges from 20 degrees to 35 degrees; the air supply mechanism further comprises a flow guide component for guiding the flowing direction of air flow. The problems that the air supply duct is limited by space, the sectional area of the air supply duct is small, and the air volume requirement of an air supply area is difficult to meet are solved.
本发明涉及双层动车通风技术领域,且公开了一种合流异型风道结构。包括主风道,所述主风道前侧设有出风口,出风口端部设有端部法兰,主风道后侧设有送风机构,用于输送风量;所述送风机构包括贯穿连接在主风道后侧的两个呈对称排布的送风管,送风管的端部开设有进风口,进风口处设有接口法兰,接口法兰和端部法兰处可通过螺栓将主风道及送风管固定在相对应的风道上;其中,主风道的顶面截面形状为V字形,送风管倾斜设置于主风道的后侧,送风管与主风道之间的倾斜角度范围为20~35度;送风机构还包括对气流流动方向进行导向的导流部件。本发明解决了送风风道受到空间限制,导致送风风道的截面面积较小,难以满足送风区域风量要求的问题。
