Description

  The present invention relates to a heat insulating panel constituting a freezer of a refrigerated vehicle, and more particularly to a heat insulating panel connecting structure for a refrigerated vehicle that connects a plurality of heat insulating panels.

  A refrigeration vehicle is a truck equipped with a freezer for transporting low-temperature cargo such as frozen food and chilled food while maintaining its quality. The freezer of this refrigeration vehicle is provided with an evaporator inside a freezer surrounded by wall surfaces, floor surfaces, and ceilings made of heat insulating material, and provided with a freezing condenser unit outside the freezer, and is cooled by this freezing condenser unit. The refrigerant is sent to the evaporator, and the refrigerant evaporating here takes the heat in the freezer and lowers the temperature in the refrigerator.

Various inventions have been proposed for the structure of such a freezer of a refrigerated vehicle. For example, as disclosed in Japanese Patent Application Laid-Open No. 8-1559639 of “Patent Document 1”, a structure of a cargo box for transporting a frozen product of a truck such as a van truck or a van trailer has been proposed.

  This freezer carton box is a vehicle-mounted freezer carton box that has six surrounding surfaces surrounded by a heat-insulating wall surface. At least the ceiling, front wall, and side wall surfaces of the six surrounding surfaces are outer metal plates. Is provided with a heat insulating layer made of a synthetic resin foam material. Furthermore, it has a three-layer structure in which a plate member is provided on the inner side of the heat insulation layer, and a recess is formed in the heat insulation layer while leaving a synthetic resin foam between the outer metal plate, and the depression surface extends from the plate member. A plate material is affixed, an evaporator for refrigeration equipment is disposed in the recess, and the evaporator is disposed at a position where the outer surface of the evaporator does not protrude from the same plane as the wall surface, and a groove for air circulation communicating with the recess is provided on the wall surface. Formed.

  However, since the freezer of a conventional refrigeration vehicle is a combination of a ceiling panel, a front wall, and a wall surface of a side wall so that each of the heat insulation panels becomes six sides, for example, a part of the side wall causes a traffic accident. When it was damaged, all of the insulation panels had to be replaced and repaired. In spite of a narrow damaged part of a part of a large area insulation panel, replacing one insulation panel was a costly loss. Moreover, despite the fact that there is still a part that can be used sufficiently, the disposal of this one heat insulation panel has a problem of affecting the environmental problems.

  Therefore, the inventors of the present invention have broken the individual ceiling, front wall, and side wall walls constituting the freezer of the refrigeration vehicle into six sides by dividing one thermal insulation panel into a plurality of pieces. Focused on exchanging and repairing only the parts.

Various inventions have been proposed for techniques for connecting such heat insulating panels divided into a plurality of sheets. For example, as disclosed in Japanese Patent Application Laid-Open No. 10-68268 of Japanese Patent Application Laid-Open No. 10-68268, a structure of a heat insulating material that blocks a heat bridge between a room interior and an outdoor space is proposed.

It is supposed that indoor side mold materials are connected by a heat insulating bridge material.

  However, since the heat insulating material of Patent Document 2 is intended for buildings, the structure of such a heat insulating material including a heat insulating bridge material has an outside air temperature range of 0 ° C. to 30 ° C., and the room temperature is Since a temperature difference of about 10 ° C. to 25 ° C. is insulated, a high heat insulation effect is not required.
