Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a main body of a motor vehicle capable of performing energy saving air conditioning in the vehicle.

[0002]

2. Description of the Related Art In recent years, there has been a demand for achieving a comfortable space such as cooling and heating with resource saving due to a problem of depletion of energy resources and a problem of destruction of a natural environment.

Here, in the case of an air conditioner (car cooler) for an automobile, the body of the automobile is made of an iron plate such as a thin steel plate, and it is a reality that little consideration is given to heat insulation.

[0004]

However, in this case, since the body is made of an iron plate, the load is large due to the high temperature of the body during cooling in summer and the like, and the car cooler consumes extra energy. was there.

According to the present invention, in order to effectively cope with the above-mentioned problems, a vehicle interior is formed by using a vacuum heat insulating material in an automobile body, and air conditioning can be performed efficiently and without wasteful use of energy. An object of the present invention is to provide a vehicle body having such a structure.

[0006]

According to the first aspect of the present invention, in a vehicle equipped with a vehicle air conditioner, a roof of a vehicle compartment,
And the door part has a vacuum heat insulating material inside.

According to a second aspect of the present invention, a silica fiber is used as a heat insulating filler of the vacuum heat insulating material.

According to a third aspect of the present invention, the vacuum heat insulating material is provided between the iron plate on the outer surface of the roof and the ceiling surface formed of a reinforced resin or the like, which is used as an interior surface material of the vehicle, in the roof of the vehicle. Vacuum insulation material, and in the door portion, a vacuum heat insulation material is provided between the iron plate of the outer surface member forming the door and the iron plate material inside the door or the inner surface material of the door made of resin, the roof portion having a multilayer structure and It is a door part.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall view of a car, and a car body 1 is shown.
Is mounted with an air conditioner for a vehicle that cools and heats the interior of the vehicle compartment (inside the vehicle) 4. The air conditioner is composed of a refrigerant compressor, a condenser, an evaporator, and the like. The operation of a refrigeration cycle formed by connecting these in a ring with refrigerant pipes causes heat exchange air to be sent to the passenger compartment 4 for air conditioning. Done.

Here, the cabin 4 is constructed by using the vacuum heat insulating material 6 for the roof 2 and the doors 3, 3 constituting the cabin 4. That is, as shown in FIG. 2, for example, in the roof portion 2 of the passenger compartment 4, the outer iron plate 5 serving as the roof surface of the passenger compartment 4.
A vacuum heat insulating material 6 is provided between the interior surface material of the passenger compartment 4 and a ceiling surface 7 formed of a reinforced resin or the like.

The vacuum heat insulating material 6 is used for showcases and refrigerators because of its high heat insulating performance, and is used together with a foam heat insulating material to form these heat insulating boxes.

As shown in FIGS. 3 and 4, the vacuum heat insulating material 6 has a vacuum barrier property formed by sandwiching a metal foil 11 such as an aluminum foil between upper and lower resin materials 9 and 10 in a sandwich manner. The laminated film 8 is used as a covering material, and a fiber material 12 such as glass wool as a core material (a heat insulating material for filling) and a binder mixed therewith are filled therein. 8) are joined, sealed, and vacuum-packed. Here, in addition to glass wool, if a material having excellent heat resistance such as silica fiber is used as the core material, the silica fiber can withstand a temperature of 190 degrees Celsius. preferable.

Therefore, when the above-mentioned roof portion 2 of the passenger compartment 4 is formed of the vacuum heat insulating material 6, a vacuum heat insulating material panel 6 as shown in FIG.
It is possible to install and arrange a plurality of these without gaps between the iron plate 5 of the roof and the ceiling surface 7.

Further, the roof portion 2 of the car has a triple structure with the uppermost iron plate 5, the lowermost ceiling surface 7, and the intermediate vacuum heat insulating material 6 interposed therein, so that the rigidity of the roof portion 2 is increased. Also comes up.

Further, since the doors 3 and 3 are also portions that substantially close the passenger compartment 4 in terms of area, the vacuum heat insulating material 6 is also used in this portion, and the vacuum heat insulating material 6 is put inside the door to improve the heat insulating property. Be enhanced. Also in this case, a plurality of vacuum heat insulating material panels conforming to the door shape are provided between the iron plate of the outer surface member forming the door portions 3 and 3 and the iron plate material inside the door or the door inner surface material made of resin. This can be achieved by doing

As described above, the roof part 2 and the door parts 3 and 3 of the car are provided.
For example, if a vacuum heat insulating material 6 is used in the vehicle compartment portion 4 and the main body 1 of the automobile has a structure having the vacuum heat insulating material inside, the air conditioning in the vehicle compartment 4 is effectively performed by the vacuum heat insulating material effect. Particularly, a rise in temperature during parking in summer is suppressed, and a cooling load is reduced, so that significant energy savings can be expected.

[0017]

As described above, according to the first aspect of the present invention, since the vacuum heat insulating material is provided in the roof of the passenger compartment and the door, the heat insulating property is improved, and the interior of the vehicle is efficiently provided. Air conditioning is performed. In particular, the rise in temperature during parking in summer can be effectively suppressed, thereby reducing the cooling load and contributing to energy saving.

According to the second aspect of the present invention, since the silica fiber having excellent heat resistance is used as the vacuum heat insulating material, the fire resistance and safety of the vehicle are sufficiently considered.

According to the third aspect of the present invention, since the roof and the door of the car have a triple structure by having the vacuum heat insulating material inside, the rigidity can be expected to be increased, and the structure is used as a structure for improving the safety of the car. it can.
