Abstract

PROBLEM TO BE SOLVED: To perform optimum divisions within a container in a weight distribution, volume within the container and heat conduction by changing thickness of a sandwich panel according to set temperature environments. SOLUTION: In a temperature control vehicle such as a cold reserving vehicle using a sandwich panel, thickness of a core material 2 of a sandwich panel constituted of an outside plate 1, the core material 2 and an inside plate is made different on the low temperature side and on the high temperature side and the low temperature side requiring thickness is made thick by overlapping the core materials 2 for raising bulk. The inside plate is made of a rear plate 3b with an end part bent into an L-type in the same way as a front plate 3a with an end part bent into the L-type. The end part of the front plate 3a and the end part of the rear plate 3b are integrally adhered via a heat insulating body 5. At a portion of the heat insulting body 5, a partition plate 6 partitioning the low temperature side and the high temperature side is provided.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a sandwich panel for a vehicle.

[0002]

2. Description of the Related Art In an insulated car or the like, when it is attempted to control the temperature of two chambers before and after partitioning by using a sandwich panel, the low-temperature storage room may be set to a constant-temperature management and the high-temperature storage room may not be controlled. . At this time, if the side wall material having a uniform cross section is used for the side walls of both the low-temperature side and the high-temperature side storage chambers, the heat insulation thickness is set according to the low-temperature side. In this structure, the high-temperature side was insulated more than necessary, and the internal volume of the refrigerator was correspondingly reduced and the increase in the body weight was inevitable. In addition, there is a problem in the temperature distribution around the partition due to heat conduction back and forth through the inner plate.

SUMMARY OF THE INVENTION It is an object of the present invention to change the thickness of a sandwich panel in accordance with a set temperature environment so that the interior of the compartment can be optimally divided in terms of weight distribution, interior volume, and heat conduction. And

[0004]

SUMMARY OF THE INVENTION In a temperature control vehicle such as an insulated vehicle using a sandwich panel, a core material of a sandwich panel composed of an outer plate 1, a core material 2, and an inner plate 3 on a low temperature side and a high temperature side. The thickness of No. 2 was changed, and a core material for raising the thickness was overlapped on the low temperature side where the thickness was required, and the thickness was increased. The front plate 3a constituting the inner plate 3 has an end 7a bent into an L shape, the rear plate 3b has an end 7b whose end is bent into an L shape, and the L of the front plate 3a is The end 7a bent into a mold and the end 7b bent into an L-shape of the rear plate 3b are integrally bonded and fixed via a thermal insulator 5, and a low-temperature storage room and a high-temperature storage A partition plate 6 for partitioning the room was provided.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. In FIG. 1, 1
Is an outer plate, 2 is a core material, 3 is an inner plate, which comprises a front plate 3a and a rear plate 3b. 4 is a raised core material further raised to a low temperature side. Reference numeral 5 denotes a thermal insulator provided at a partition between the low temperature side and the high temperature side. Reference numeral 6 denotes a partition plate.

The outer plate 1, the core material 2, the inner plates 3a and 3b, and the raised core material 4 on the low-temperature side are respectively adhered and integrated with an adhesive. As the outer plate 1, a thin plate such as aluminum or FRP is used, and a single plate is usually preferred. Foamed plastics are used for the core material 2 or 4, and the thickness is suitable for the high-temperature storage room, and the low-temperature storage room further raises the core material 4 by an appropriate thickness. The inner plates 3a and 3b are made of aluminum, painted steel, or the like, and are provided with ends 7a and 7b bent into an L-shape at ends that are boundaries between the high-temperature storage room and the low-temperature storage room. These ends 7a and 7b are adhesively fixed. When manufacturing the sandwich panel A, an adhesive is applied in advance to the mating surfaces of the constituent members, and a single sandwich panel having a different thickness between the low-temperature side and the high-temperature side by bonding these materials under pressure. Become. The partition 6 that partitions the low-temperature side and the high-temperature side compartments is attached to the heat insulating material 5.

In the above description, the side wall structure has been described. However, the present invention can be applied not only to the side wall but also to a roof shingle. By combining the both, more excellent effects can be obtained.

[0008]

By making the cross section of the side wall different in thickness between the low temperature side and the high temperature side, it is possible to provide a structure adapted to the thermal characteristics of the divided room and the required volume, and to reduce the weight. Can be. Also, the inner plate is divided into a front plate on the low temperature side and a rear plate on the high temperature side, and the L-shaped ends of the front plate and the rear plate are bonded and fixed via the thermal insulator 5 so that the front and rear sides are fixed. The heat conduction of the storage room can be cut off. The desired sandwich panel can be obtained by using the adhesive application and pressurizing steps that are the manufacturing process of the sandwich panel, so the number of manufacturing steps can be reduced compared to the method of adding heat insulating material later. .
