Abstract
The utility model relates to the field of automobile air conditioners, in particular to an air conditioning cabinet shell body for a passenger car. A low-noise air conditioning cabinet shell body for the passenger car comprises an evaporator shell body. A baffle is arranged on a fresh air inlet of the evaporator shell body. The baffle is in a crescent shape. A protrusion is arranged at the center of an inner ring of the crescent. According to the low-noise air conditioning cabinet shell body, the crescent-shaped baffle with the appropriate size is arranged in a position, close to a vortex tongue, of an air inlet of an air conditioning cabinet, and is capable of reducing noise of the air inlet and decreasing backflow sounds of an air conditioner caused by an impeller in the process of inducing air. The low-noise air conditioning cabinet shell body can be adopted for air inlet devices of air blowers of the air conditioning cabinets in different vehicle types to reduce the noise of the air inlet, and optimizes noise quality of the air blowers. Tests prove that the low-noise air conditioning cabinet shell body for the passenger car is capable of reducing the noise of 1 decibel (dB).
Description
Technical field
The utility model relates to the air conditioning for automobiles field, relates in particular to a kind of passenger vehicle air conditioner tank shell.
Background technology
Along with the development of auto industry, the client requires more and more higher to the comfort level in car, in various cars, in noise, heats, and the noise of heating ventilation and air-conditioning system HVAC can cause driver's attention.With respect to other noise, the noise of HVAC is not maximum, but but may cause the nervous and bored of the interior driver of car and passenger, affects the comfort level of automobile.Therefore, the height of noise becomes the major criterion of passing judgment on a HVAC quality.
In the various factors that causes the air-conditioning box noise, the noise caused by air blast is that accounting is heavy maximum, by optimizing the air inlet duct of air blast, improves the fit system between spiral case and impeller, can effectively reduce the noise of whole air-conditioning box.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of low noise passenger vehicle air conditioner tank shell, the backflow sound of the air-conditioning caused in the air inducing process of the noise of suitable crescent baffle plate reduction air inlet and minimizing impeller by the place increase size at the close whirlpool of air-conditioning box air inlet tongue is tested the noise that can reduce 1dB under same test conditions.
The utility model is achieved in that a kind of low noise passenger vehicle air conditioner tank shell, comprises evaporator shell, described evaporator shell advance on fresh wind port to be equipped with baffle plate, described baffle plate is crescent, the inner ring center of crescent moon is provided with a projection.
What the area of described baffle plate accounted for evaporator shell advances 9% ~ 15% of fresh wind port area.
What the area of described baffle plate accounted for evaporator shell advances 12.6% of fresh wind port area.
Between straight line between the central point of described baffle plate protrusions and whirlpool root of the tongue section central point and horizontal plane, angulation α is 28 ° ~ 35 °.
Between straight line between the central point of described baffle plate protrusions and whirlpool root of the tongue section central point and horizontal plane, angulation α is 32.5 °.
The utility model low noise passenger vehicle air conditioner tank shell increases near the place of whirlpool tongue the crescent baffle plate that size is suitable at the air-conditioning box air inlet, can reduce the noise of air inlet and reduce the backflow sound of the air-conditioning caused in the air inducing process of impeller; The air-conditioning box blower inlet device of different automobile types, can adopt this kind of structure to reduce the noise of air inlet, optimizes air blast noise quality, shows to reduce the noise of 1dB through test.
The accompanying drawing explanation

As shown in Figure 1, 2, 3, a kind of low noise passenger vehicle air conditioner tank shell, comprise evaporator shell 1, described evaporator shell 1 advance on fresh wind port to be equipped with baffle plate 2, described baffle plate 2 is crescent, the inner ring center of crescent moon is provided with a projection 3; In the present embodiment, described protruding 3 is straightway, projection 3 and the interior circular arc line smooth transition of the crescent moon at two ends, by baffle plate 2, can substantially not reduce on the basis of intake volume, reduce the noise of air-conditioning box integral body, after verification experimental verification has been installed baffle plate 2, air-conditioning box can reduce the noise of 1dB under identical experiment condition, and can effectively reduce the backflow sound of gas at tongue place, whirlpool, improve the noise quality.
In the utility model, what the area of described baffle plate 2 accounted for evaporator shell 1 advances 9% ~ 15% of fresh wind port area.
As preferably, what the area of described baffle plate 2 accounted for evaporator shell 1 in the present embodiment advances 12.6% of fresh wind port area.
In the utility model, between the straight line between the central point of described baffle plate 2 protrusions 3 and whirlpool root of the tongue section 4 central points and horizontal plane, angulation α is 28 ° ~ 35 °.
As preferably, between the central point of 2 protrusions 3 of baffle plate described in this enforcement and the straight line between whirlpool root of the tongue section 4 central points and horizontal plane, angulation α is 32.5 °.
