Problems solved by technology

[0008] For this reason, in the manufacturing process of the above-mentioned prior art, in order to prevent the leakage of the foaming agent when foaming the foaming agent, it is necessary to install rivets or tools on the housing, which increases the work. The process increases the cost, and in order to wait for the sealing material to dry and perform foaming work, it also prolongs the production time, which is a problem

Embodiment Construction

[0046] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. In addition, the description of the following preferred embodiments is merely an example in nature, and is not intended to limit the applicable objects and uses of the present invention.

[0047] Such as figure 1 As shown, the container refrigeration device 10 according to this embodiment is installed on one end surface of the sea transportation container 1 . The container refrigeration device 10 is configured to cool the interior of the container (refrigeration or freezing) by circulating a refrigerant through a refrigerant circuit (not shown) to perform a refrigeration cycle.

[0048] Such as figure 2 As shown, the container refrigeration device 10 includes a casing 20 whose peripheral portion is installed on the container body 2 so as to block the opening end surface of the bottomed cylindrical container body 2 . That is, the housing 20 becomes one end surface of...

Abstract

A casing structure of freezer for container having an outside casing and an inside casing provided therebetween with a heat insulating layer that while preventing any leakage of foaming agent at the formation of the heat insulating layer, realizes shortening of working time and reduction of manufacturing cost. The flange (34) of outside casing (30) on its inside surface (30a) is provided with rib(34c) so as to lock the peripheral edge (35b) of inside casing (35) at the time of foaming of foaming agent (38) in the foaming space (V) between the outside casing (30) and the inside casing (35). Atleast one of the interior of the interstice between the peripheral edge (35b) of the inside casing (35) and the inside surface (30a) of the outside casing (30) and the side of foaming space (V) of the interstice is provided with sealing medium (40).

Description

technical field [0001] The present invention relates to a housing structure of a container refrigeration device installed by sealing the end surface of the container body to cool the container type refrigerator, and particularly relates to preventing the foaming of the foaming agent in order to form a heat insulating layer. Measures for shell deformation. Background technique [0002] Conventionally, as a container refrigeration device for cooling the interior of a container-type refrigerator used for marine transportation, for example, a refrigeration device having a structure such as Patent Document 1 is known. [0003] The container refrigerating device includes a refrigerant circuit connecting a compressor, a condenser, and an evaporator through refrigerant lines, and a casing installed so as to cover one side opening of a container body in which a cargo box is formed. In addition, in the refrigerator for a container, the compressor and the condenser are installed outsi...
