Abstract

A kind of noise reduction air door of concave-convex surface grain shape, the surface distributed at air door has concavo-convex granule, concavo-convex granule be shaped as irregular shape.This utility model is by some the most concavo-convex grain shapes of Surface Machining at air door, when air-flow at a high speed through damper surface when, air-flow can be reflected, scatters, reflect and rectification by these concavo-convex grain shapes, thus the wind reducing air conditioning for automobiles is made an uproar, improve the gas flow temperature uniformity through this kind of damper surface the most to a certain extent.

Description

A kind of noise reduction air door of concave-convex surface grain shape

Technical field

This utility model patent belongs to field of automobile air conditioner, is related specifically to air door.

Background technology

Along with the development of society, automobile has also progressed into huge numbers of families.Automobile is while ensureing safety, reliability, and nowadays the requirement to comfortableness the most more focused on by the most high-end automobile of automobile.Along with to air conditioning for automobiles Wind Volume, the requirement of small size is more and more higher, cause air-conditioning air inlet, air outlet, air velocity within air-conditioning is more and more higher, thus causing the biggest wind to be made an uproar, the air door of existing air conditioning for automobiles can not meet the needs that low air-conditioner wind is made an uproar, thus constrains the raising of air conditioning for automobiles comfort level.

Summary of the invention

The purpose of this utility model is to provide a kind of noise reduction air door with concave-convex surface grain shape, thus the wind reducing air conditioning for automobiles is made an uproar.

For achieving the above object, the technical solution of the utility model is:

A kind of noise reduction air door of concave-convex surface grain shape, it is characterised in that: the surface distributed at air door has concavo-convex granule, concavo-convex granule be shaped as irregular shape.

The advantage of this utility model patent is: this utility model is by some the most concavo-convex grain shapes of Surface Machining at air door, when air-flow at a high speed through damper surface when, air-flow can be reflected, scatters, reflect and rectification by these concavo-convex grain shapes, thus the wind reducing air conditioning for automobiles is made an uproar, improve the gas flow temperature uniformity through this kind of damper surface the most to a certain extent.

Accompanying drawing explanation

Fig. 1 is this utility model structural representation.

Detailed description of the invention

1 the utility model is described in further detail below in conjunction with the accompanying drawings.

The noise reduction air door of a kind of concave-convex surface grain shape has concavo-convex granule 1 in the surface distributed of air door 2, concavo-convex granule 1 be shaped as irregular shape.The shape of concavo-convex granule 1, orientation, quantity, distribution etc. can be adjusted according to fluid analysis result, noise test result etc. according to the wind speed of damper surface, wind direction, the factor such as structure of air-conditioning.

Claims (1)

1. the noise reduction air door of a concave-convex surface grain shape, it is characterised in that: the surface distributed at air door (2) has concavo-convex granule (1), concavo-convex granule (1) be shaped as irregular shape.
