Embodiment Construction
[0015] The present invention as figure 1 , 2 shown.
[0016] The cross-flow air supply device of the automobile air conditioner includes a cross-flow fan impeller 4 and a control panel 2, and a wind deflector 7 that is consistent with the wind direction is vertically provided in the middle of the air inlets 5 and 6 of the cross-flow fan impeller 4. The height of the plate 7 is higher than the height of the air inlet, and the inner side in the width direction is more than 10mm away from the outer circle of the cross-flow fan impeller 4; The distance between the arc wind deflector 8 and the outer circle of the cross-flow fan impeller 4 is more than 5mm.
[0017] A plurality of arc ribs 11 are arranged radially on the circular-arc wind deflector 8 , and the center of the circular-arc wind deflector 8 is centered on the cross-flow fan impeller 4 .
[0018] Because the arrangement of the air inlets 5 and 6 and the air inlets are not parallel and offset, the wind deflector 7 is a...

The invention provides a cross-flow type air supply device of an automotive air conditioner. Air guide plates are vertically arranged in the middle portions of air inlets of an impeller of a cross-flow fan, the direction of the air guide plates is consistent with the air direction, the air guide plates are higher than the air inlets, and the inner sides, in the width direction, of the air guide plates are over 10 mm away from the impeller of the cross-flow fan; an arc-shaped air guide plate is arranged between air outlets of the impeller of the cross-flow fan and located below a control panel, arc-shaped ribs are arranged on the arc-shaped air guide plate in the radial direction with the center of the impeller as the center, and the distance between the arc-shaped ribs and the outer circle of the impeller of the cross-flow fan is over 5 mm. By the adoption of the air guide plates, the air speed at the air inlets can be more uniform, and murmurous air noise caused by disordered air directions can be lowered; by the adoption of the arc-shaped air guide plate and the arc-shaped ribs, the rotational movement locus of the impeller of the cross-flow fan is guaranteed, the operation safety of the impeller is guaranteed, and the normal flow of outlet air at the air outlets can be achieved; the cross-flow type air supply device is simple in structure, economical and practical, and unpleasantness caused by the irregular air noise generated when the cross-flow type air supply device is used by a customer is avoided.
Description
technical field [0001] The invention relates to automobile air-conditioning components, in particular to a through-flow air supply device. Background technique [0002] At present, the fan length of the cross-flow air supply device for automobiles is more than 350mm. For such a long fan, the vehicle factory considers the appearance, and the air inlet, air outlet and control panel layout may block the area of the fan. If the above situation occurs, due to the characteristics of the cross-flow fan (the airflow flows through the impeller and is affected by the two forces of the blades), the wind direction will be disordered, resulting in loss of air volume and rustling wind noise, which will affect the comfort of customers. [0003] The traditional overhead air conditioner has a tube-fin evaporator core at the air inlet of the cross-flow fan, which objectively plays a role in diverting air, so this problem does not exist. Contents of the invention [0004] The present inv...
