Description

TECHNICAL FIELD [0001] The present invention relates to an air conditioning system for an automobile,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle air conditioning system, and more particularly, to a vehicle air conditioning system capable of significantly reducing manufacturing costs by reducing unnecessary parts within a limit that does not deteriorate heating performance.

The automobile is provided with an air conditioning system for cooling and heating the room.

The air conditioning system is configured to selectively open the outer air inlet 12 and the inner air inlet 14 of the air conditioning case 10 with the intake door 20 as shown in Fig. The inside and outside air is cooled or heated by an evaporator and heater (not shown). And supplies cooled or heated air to the interior of the vehicle. Accordingly, the interior of the vehicle is cooled and heated.

On the other hand, in an air conditioning system, it is an important task to reduce the manufacturing cost by reducing the number of parts within a range that does not deteriorate the cooling / heating performance.

As a method of cost reduction, there is a method of reducing the manufacturing cost by eliminating unnecessary parts count. For example, in the case of an export specification to a cold area where cooling is not required, the number of parts is reduced by eliminating the heat exchanger necessary for cooling. Therefore, the manufacturing cost is reduced.

However, despite the cost reduction by reducing the number of parts, the demand for cost reduction is still increasing. Particularly, when it is applied to a low-cost vehicle, the demand for cost reduction is further increased in order to lower the cost of the vehicle.

Therefore, it is very important to further reduce the manufacturing cost by further reducing the number of unnecessary parts within the limit of not lowering the heating performance.

For example, since the necessity of selection of the inside and outside air is low at the time of heating, the intake door 20 necessary for selecting the inside and outside air, and the actuator and the link member for operating the door are unnecessary. Therefore, when the cooling heat exchanger is removed, it is important to reduce the manufacturing cost by eliminating the intake door 20, the actuator, and the link member.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle air conditioning system capable of significantly reducing the manufacturing cost by further reducing the number of unnecessary parts within a limit that does not deteriorate the heating performance There is.

Another object of the present invention is to provide a vehicle air conditioning system capable of improving the competitiveness of a product by significantly reducing manufacturing costs.

In order to achieve the above object, a vehicle air conditioning system of the present invention comprises: an air conditioning case having an outer air inlet and an inner air inlet; a blower blowing in and outside air through the outer air inlet and the inner air inlet, And a heater for heating the inside and outside air blown into the passenger compartment, the system comprising: an air inlet opening and an air inlet opening for blocking the flow of outside air directly flowing from the outside air inlet to the inside air inlet; And a stationary separating wall provided on the air passage between the two side walls.

Preferably, the fixed partition wall extends to the suction port portion of the blower, and blocks the outdoor air and the indoor air introduced into the outdoor air inlet and the indoor air inlet so as to be separated from each other until the air is introduced into the inlet .

According to the vehicle air conditioning system of the present invention, since the intake door and various devices for operating the intake door can be eliminated, the heater-only type air conditioning system can reduce the number of components as much as possible without lowering the heating performance .

Further, since the number of components can be reduced to the utmost without lowering the heating performance, the manufacturing cost can be remarkably reduced.

In addition, since the manufacturing cost can be significantly lowered, it is possible to improve the competitiveness of the product.

In addition, since the fixed partition wall is provided at the portion where the intake door is removed, the outer air inlet and the inner air inlet are separated from each other, so that the outer air inlet and the inner air inlet can be easily separated without the intake door.

In addition, since the outside air inlet and the inside air inlet can be separated without an intake door, it is possible to shut off the outside air flowing into the outside air inlet from the outside air inlet without the intake door. As a result, Can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a vehicle air conditioning system according to the present invention will be described in detail with reference to the accompanying drawings (the same components as those in the prior art are denoted by the same reference numerals).

FIG. 2 is a perspective view showing a vehicle air conditioning system according to the present invention, and FIG. 3 is a cross-sectional view showing a coupled state of FIG.

First, a vehicle air conditioning system will be briefly described with reference to FIG. 2 before a characteristic portion of a vehicle air conditioning system according to the present invention is examined.

The air conditioning system for a vehicle has an air conditioning case 10 in which an outer air inlet 12 and an inner air inlet 14 are formed.

The outside air inlet 12 communicates with the outside of the vehicle, and introduces air outside the vehicle into the inside of the air conditioner case 10. The indoor air inlet 14 communicates with the interior of the vehicle, and introduces indoor air.

Here, the outer air inlet 12 is configured to face the running direction of the vehicle. This is to allow the running wind of the vehicle to be smoothly introduced into the outside air inlet 12.

The air conditioning system includes a blower 30. The blower 30 includes a scroll casing 32, a centrifugal fan 34, and a blower motor 36 for driving the centrifugal fan 34.

The blower 30 sucks the inside and outside air of the vehicle through the outside air inlet 12 and the inside air inlet 14, and then blows the sucked inside and outside air into the inside of the vehicle.

Next, the features of the air conditioning system for a vehicle according to the present invention will be described in detail with reference to FIG. 2 and FIG.

First, the air conditioning system of the present invention has a configuration for removing the intake door 20 (see FIG. 1) for selectively opening the outer air inlet 12 and the air intake port 14.

Further, the intake door 20 is removed, and an actuator (not shown) and a connecting arm (not shown) for driving the intake door 20 are also deleted.

Thus, when the intake door 20 is removed, the inner air inlet 12 and the outer air inlet 14 are opened at the same time. Accordingly, when the blower 30 is operated, both the indoor air and the outdoor air are introduced at the same time, and the introduced indoor and outdoor air are introduced into the inner passage 10a of the air conditioning case 10 while being mixed with each other.

Particularly, in the case of a heater only type air conditioning system which is an export specification to a cold region, the inside and outside air introduced into the internal passage 10a of the air conditioner case 10 passes through a heater (not shown) And the heated air is introduced into the interior of the vehicle, thereby heating the interior of the vehicle.

Referring again to Figs. 2 and 3, the air conditioning system of the present invention has a structure in which a fixed separation wall 50 is provided at a portion of the intake door 20 that has been removed.

The fixed separation wall 50 extends from the air conditioning case 10 and is disposed between the outer air inlet 12 and the inner air inlet 14. In particular, it is installed on the air passage 15 between the outer air inlet 12 and the inner air inlet 14 so as to prevent direct communication between the outer air inlet 12 and the inner air inlet 14.

The fixed separation wall 50 is provided between the outer air inlet 12 and the inner air inlet 14 so as to prevent direct communication between the outer air inlet 12 and the inner air inlet 14, It blocks direct air flow.

In particular, it blocks the flow of outside air flowing from the outer air inlet 12 to the inner air inlet 14. Thus, the high-pressure running air introduced into the outer air inlet 12 is prevented from flowing into the inner air inlet 14.

As a result, the outdoor air introduced into the passenger compartment through the outdoor air inlet 12 and the outdoor air inlet 14 without any heat exchange is intrinsically blocked, whereby the heating performance of the vehicle The degradation phenomenon can be prevented in advance.

The fixed partition wall 50 is configured such that its end portion extends to the portion of the inlet ring 38 of the blower 30. In particular, it is configured to extend to a portion of the suction port 39 formed in the inlet ring 38.

Thus, the outside air inlet 12 and the outside air inlet 14 are blocked from being separated from each other until the outside air and the inside air introduced into the inlet 39 of the blower 30 are introduced. At the same time, the outer air inlet 12 and the inner air inlet 14 are guided to the air inlet 39 of the blower 30.

Preferably, the fixed separation wall 50 extends toward the suction port 39 and extends so as to divide the suction port 39 into two. In particular, it may extend toward the central portion of the suction port 39 so as to divide the suction port 39 into equal sizes.

This is to keep the external quantity introduced into one of the parts 39a and 39b of the intake port 39 equal to the internal quantity of the other part 39b of the suction port 39, And 1: 1, so that the heating performance of the interior of the vehicle can be improved.

In addition, it is preferable that the fixed partition wall 50 is formed in a streamlined shape with its end portion having a constant curvature along the thickness direction. This is to prevent abrupt fluctuation of the air in contact with the end of the fixed separation wall 50, thereby preventing flow noise due to abrupt fluctuation of the air.

Preferably, at the end of the fixed separation wall 50, a rim 52 having a circular cross section with a diameter larger than the thickness is formed. Thus, abrupt change of the air in contact with the end portion of the fixed separation wall 50 is prevented, thereby preventing air flow noise.

According to the present invention, since the intake door 20 and various devices for operating the intake door 20 can be eliminated, the heater-only type air conditioning system can reduce the number of components as much as possible without lowering the heating performance .

In addition, since the number of components can be reduced to the utmost without deteriorating the heating performance, the manufacturing cost can be greatly reduced.

In addition, since the manufacturing cost can be significantly lowered, the competitiveness of the product can be improved.

Since the stationary separation wall 50 is provided at the portion where the intake door 20 is removed to separate the outer air inlet 12 and the inner air inlet 14 from each other, 12 and the inner air inlet 14 can be easily separated from each other.

Since the outside air inlet 12 and the inside air inlet 14 can be separated from each other without the intake door 20, the outside air entering from the outside air inlet 12 to the inside air inlet 14 without the intake door 20 As a result, it is possible to prevent direct entrance of outside air through the ventilation opening 14 into the room.

Next, FIG. 4 is a view showing another embodiment of the present invention.

The present invention of another embodiment further includes a filter 60 provided between the inner and outer air introduction ports 12 and 14 and the blower 30. [

In another embodiment of the present invention, the fixed separation wall 50 is configured to extend toward the filter 60. [

In particular, the end of the fixed separation wall 50 is configured to be close to the upper side of the filter 60. Thus, the outside air inlet 12 and the outside air inlet 14 are blocked from being separated from each other until the outside air and the inside air introduced into the inlet 60 enter the filter 60.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
