Problems solved by technology
[0002] Such a vehicle air conditioner has the disadvantage that when the cooling air comes into contact with the wall facing the cooling heat exchanger, dew will condense on the casing surface of this part, and the dew condensation will wet the vehicle interior and the like when it drops.
[0005] However, in the above-mentioned structure, since a heat insulating member must be provided, the product cost increases, and the heat insulating member itself is made of a raw material different from the air-conditioning casing, so it cannot be integrated with the air-conditioning casing, and must be laid on the air-conditioning casing in a subsequent process. Assembled on the air conditioner housing
Therefore, there are disadvantages such as increased assembly man-hours of the air conditioner.

Embodiment Construction
[0026] Next, preferred embodiments of the present invention will be described with reference to the drawings.
[0027] exist figure 1 The middle figure shows the mid-mounted air conditioner 1 mounted on the center bracket portion of the vehicle. This air conditioner 1 is installed on the vehicle compartment side of the partition for dividing the engine room and the vehicle compartment, and filters 4 are arranged and accommodated in the air conditioner case 3 in which the air flow path 2 is formed, along the front-rear direction of the vehicle. , the evaporator 5 and the heater core 6, the air blower 7 is provided on the upper part of the filter 4 and the evaporator 5 in the air-conditioning case 3, and by rotating the blower 7, the blower is blown through The air port introduces internal air or external air into the air conditioner casing.
[0028] The filter 4 and the evaporator 5 are vertically installed so as to pass all the air introduced into the air-conditioning case ...

The present invention provides an air conditioning device for a vehicle which prevents condensation generated on a case surface of a part opposed to a downstream side end surface of a heat exchanger for cooling without using heat insulating materials, and reduces not only product cost but also man-hour for installation. The air conditioning device for the vehicle has an air conditioning case forming an air passage in an inside, and an evaporator capable of cooling the air which is stored and introduced in the air conditioning case. In the air conditioning device for the vehicle, an opposed wall part opposing to the downstream side end surface of the evaporator is formed on the downstream side of the evaporator of the air conditioning case. A guide plate covering the opposed wall part is provided by separating the opposed wall part in the air conditioning device. The guide plate is extended so that an effective heat exchanging part of the evaporator does not oppose to the opposed wall part, and inclined toward a turning area of an air mixing door. In addition, a clearance is provided between the evaporator and the air conditioning case, and the air introduced through the clearance is introduced into a blind alley 21 between the guide plate and the opposed wall part.
Description
technical field [0001] The present invention relates to an air conditioner for a vehicle, which houses a cooling heat exchanger in an air conditioning case, and forms an end surface on the downstream side of the cooling heat exchanger on the downstream side of the cooling heat exchanger of the air conditioning case. opposing opposing wall portions. Background technique [0002] Such a vehicle air conditioner has a disadvantage that when the cooling air comes into contact with the opposing wall portion facing the cooling heat exchanger, dew is condensed on the surface of the casing of this portion, and the dew drops wet the vehicle interior and the like. Therefore, in the prior art, a heat insulating material made of foamed styrene or the like is laid on the inner surface of the housing (Patent Document 1), and a shape and an inner wall of the air-conditioning housing are installed on the bottom of the cooling heat exchanger. The structure and the like of a bowl-shaped heat ...
