導率の低い真空断熱パネルの採用が考えられる。[0003] (2) A demand for a heat insulating storage for a vehicle is to increase the volume in the storage (body). Increasing the volume in the refrigerator means increasing the dimensions in the width and height directions. However, the outer frame dimensions of the storage are regulated by law. Therefore, in order to execute the enlargement of the inner size of the refrigerator with the outer frame size of the refrigerator as the regulation size, it is necessary to reduce the thickness of the wall member (heat insulating material). Here, if it is attempted to reduce the thickness of the wall while maintaining the same heat insulation performance at present, it is indispensable to improve the heat insulation of the wall member. As a means of improving the heat insulating property of the wall member, adoption of a vacuum heat insulating panel having a lower thermal conductivity than the current foamed plastic foam can be considered.
【０００４】ここで、断熱部材毎の熱伝導率を表１に示

In this way, the vacuum heat insulating member can increase the internal volume and reduce the weight due to the thinning of the wall member. In addition, when the vacuum heat insulating material is used without changing the thickness of the wall member, the heat insulating property can be improved about four times, and improvement in fuel efficiency can be expected.

Bending and twisting loads. At this time, in a structure in which the vacuum insulation panel is adhered to the outer plate, such as the wall structure of a home appliance refrigerator described in the section of the related art, when the above-described load is applied to the wall, the stress is directly applied to the vacuum insulation. It is transmitted to the panel, and the film strength may be broken without being able to endure. When the film breaks, the vacuum state cannot be maintained, and the heat insulation of the vacuum heat insulating panel is reduced. Therefore, when a vacuum insulation panel is used as a wall structural member of a transport insulation box, even if a load such as bending or twisting is applied to the wall, the stress on the film of the vacuum insulation panel becomes small. It is necessary to install in the center part in the thickness direction.

There is a possibility that an obstacle outside the refrigerator may hit the wall and damage the outer plate side. In a heat insulating wall in which a vacuum heat insulating panel is installed at a position near the inner and outer plates, if damaged, a hole is formed in the film and the heat insulating property of the vacuum heat insulating panel is reduced. Therefore,
When a vacuum heat insulating panel is used as a wall structural member of a transport heat insulating store, the vacuum heat insulating panel needs to be installed at the center in the wall thickness direction in order to avoid damage from inside and outside of the store.

Parts, rails and angles are attached with fasteners (rivets). As a rivet, a pull stem type rivet is usually used for a heat insulation cabinet. In addition, there are solid, full tubular, semi tubular, split, compression, and blind rivets.

A method of attaching the rib 16 will be described. First, drill 13
Drill a pilot hole 130c through Oa (or outer plate 130b). Thereafter, the rivet 18 is inserted and the rivet is pulled and fixed by the rivet. Although there is no problem in the case of the sandwich panel, if the vacuum heat insulating panel 25 is disposed between the inner and outer plates 130a and 130b, the film 25b may be damaged when the drill is prepared and the rivet is inserted into the hole.

約１０ｍｍくらいが安全とされている。Usually, a drill is formed by attaching a stopper so as not to enter the drill too deeply. However, the size of the stopper varies depending on the manufacturer, and the depth of the prepared hole of the drill cannot be specified unconditionally. For example, in this type of wall member, a stopper that stops at a prepared hole depth of about 15 mm may be attached to the drill. Conversely, 15mm
The rivets cannot be set unless there is a prepared hole. Therefore, the vacuum heat insulating material needs to be set at a distance from each of the inner and outer plates of about 15 mm + α and installed inside the center of the wall thickness of the wall member. Normally, it is considered that about 10 mm is safe for the preparation of the pre-drilled hole α.
