Description

A kind of warm braw assembly air channel improved structure

Technical field

The utility model belongs to automobile air conditioning technology field, and in particular to a kind of warm braw assembly air channel improved structure.

Background technology

The important component part of warm braw assembly air conditioning for automobiles.The effect of warm braw assembly is receiving using its internal air channel and air door The distribution of air-flow is realized in control logic motion, so realize the air-supply of warm braw assembly constitute on demand generally need blow face, blow pin, blow Pin is blown in face, blows five kinds of patterns of pin demisting and defrosting.Under the background that the competition of automobile industry at this stage increasingly sharpens, Ge great automobile factorys Increasingly emphasize the comfortableness of car load, so as to be similar vehicle competition in maintain the leading position can rapidly release new model with In market share one seat.Comfortableness is referred under the premise of high-performance is ensured, provides bigger comfort to passenger, such as Less noise, therefore Ge great automobile vendors wish that automobile component part supply commercial city can be developed towards the direction, and for automobile The big air quantity of air-conditioning and low noise are particularly important for automobile vendor, and existing warm braw assembly air channel is due to the structure at vortex tongue Design is unreasonable, very loud noise is often resulted in, so as to reduce heat pump performance and comfortableness.

The content of the invention

Technical problem to be solved in the utility model is the present situation for prior art, and a kind of simple structure of offer, The little warm braw assembly air channel improved structure of backflow noise.

The utility model solve the technical scheme that adopted of above-mentioned technical problem for：Improve knot in a kind of warm braw assembly air channel Structure, includes turbine space, the first duct space, the second duct space and the 3rd duct space, and wind direction is from turbine during air-out Space guides the first duct space, the second duct space and the 3rd duct space into, it is characterised in that on described turbine space With vortex tongue air outlet, described vortex tongue air outlet lower surface has a lower camber side conduction part, the upper end of described vortex tongue air outlet The drainage direction that face has upper cambered surface conduction part, described lower camber side conduction part is directed at upper cambered surface conduction part.

Here the maximum improvements of the utility model are to be improved the structure of vortex tongue air outlet, and air-out is worked as here When lower camber side conduction part due to being the upper cambered surface conduction part of direction alignment, such wind direction can just be directed to cambered surface conduction part side Backward, and because upper cambered surface conduction part has cambered surface downwardly direction, so there is a downward pressure effect to wind direction again, just Wind direction can be smoothly guided, prevents gas from moving in turbine space interior circulation, so as to substantially reduce making an uproar produced by backflow wind Sound.

The measure taken to optimize such scheme is specifically included：

In a kind of above-mentioned warm braw assembly air channel improved structure, the second described duct space upper end has oblique drainage Side, described oblique drainage while end on being folded to while, keep out the wind side with arc on the second described duct space left end, Described is folded to the place plane in keep out the wind less than arc to direction.Here direction is kept out the wind less than arc due to being folded to side Side place plane, such wind direction is just more caused arc and is kept out the wind on the flexure plane of side, and because flexure plane runner can be provided Larger resistance, prevents backflow wind from passing through.

In a kind of above-mentioned warm braw assembly air channel improved structure, the upper end porch of the 3rd described duct space has Indent flanging, in the lower end of the 3rd duct space there is the length of curved extraction bottom surface, described extraction bottom surface to be more than whirlpool The length in wheel space.Wind direction is more smoothed by the 3rd space, reduce noise.

Compared with prior art, the utility model has the advantage of the structure of vortex tongue air outlet is improved, prevent Gas is moved in turbine space interior circulation, so as to substantially reduce the noise produced by backflow wind, improves whole warm braw assembly Comfortableness.

Description of the drawings

Fig. 1 is the overall structure diagram of this warm braw assembly air channel improved structure.

Specific embodiment

The following is specific embodiment of the utility model and combine accompanying drawing, further is made to the technical solution of the utility model Description, but the utility model is not limited to these embodiments.

In figure, turbine space 1；First duct space 2；Second duct space 3；3rd duct space 4；Vortex tongue air outlet 5； Lower camber side conduction part 6；Upper cambered surface conduction part 7；Oblique drainage side 8；It is folded to side 9；Arc keeps out the wind side 10；Indent flanging 11；Draw Bottom surface 12.

As shown in figure 1, this warm braw assembly air channel improved structure, includes turbine space 1, the first duct space 2, the second wind The duct space 4 of road space 3 and the 3rd, wind direction guides the first duct space 2, the second duct space 3 into from turbine space 1 during air-out And the 3rd duct space, there is vortex tongue air outlet 5 on turbine space 1, the lower surface of vortex tongue air outlet 5 has lower camber side conduction part 6, the upper surface of vortex tongue air outlet 5 has upper cambered surface conduction part 7, the upper cambered surface drainage of drainage direction alignment of lower camber side conduction part 6 Portion 7, here the maximum improvements of the utility model are to be improved the structure of vortex tongue air outlet 5, here when air-out Due to being the upper cambered surface conduction part 7 of direction alignment, such wind direction can just be directed to the side of cambered surface conduction part 7 to lower camber side conduction part 6 Backward, and because upper cambered surface conduction part 7 has cambered surface downwardly direction, so there is a downward pressure effect to wind direction again, Wind direction just can be smoothly guided, prevents gas from moving in the interior circulation of turbine space 1, so as to substantially reduce produced by backflow wind Noise.

The upper end of second duct space 3 has an oblique drainage side 8, oblique drainage while 8 end on when being folded to 9, second Keep out the wind side 10 with arc on the left end of duct space 3, be folded to while 9 direction is kept out the wind less than arc while 10 place planes.Here Due to be folded to while 9 direction is kept out the wind less than arc while 10 place planes, such wind direction just more caused arc and kept out the wind side On 10 flexure planes, and because flexure plane runner can provide larger resistance, backflow wind is prevented to pass through, the 3rd duct space 4 Upper end porch has indent flanging 11, has curved extraction bottom surface 12 in the lower end of the 3rd duct space 4, draws bottom surface Length of 12 length more than turbine space 1, so that wind direction is more smoothed by the 3rd duct space 4, reduces noise.

Specific embodiment described herein is only explanation for example to the utility model spirit.The utility model institute Category those skilled in the art can make various modifications to described specific embodiment or supplement or using similar Mode substitute, but without departing from the defined scope of spirit of the present utility model.
