Embodiment Construction

[0029] Embodiments of the present invention will be described in detail below with reference to the drawings.

[0030] Figure 1 and figure 2 As shown, the refrigerated container 10 of this embodiment is a device for transporting cargo by a container ship or a container truck while cooling the cargo. The above-mentioned refrigerated container 10 includes a cabinet 11 for accommodating cargo inside (inside the warehouse), and a refrigeration device 12 for cooling the inside of the cabinet 11 (in the warehouse).

[0031] The casing 11 has a front panel S1, a rear panel S2, a top panel S3, a bottom panel S4, and left and right side panels S5, S6, and is formed in a substantially rectangular parallelepiped shape. In addition, in FIG. 1 , the front side represents the front side, the rear side represents the back side, and the left and right sides respectively represent the left and right sides in the direction seen from the front side.

[0032] In each of the panels S1 to S6 of t...

Abstract

A casing (11) for use in a freezing container is provided with a through hole (H) for insertion of the piping of a refrigerant circuit therethrough. Each opening end of the through hole (H) is covered over with a respective mesh sheet (31, 32). With each opening end of the through hole (H) covered over with the mesh sheet (31, 32), the tip end of a filling nozzle (33) is inserted until it reaches the middle of the through hole (H) and a sealant material is injected. The injected sealant material is held back within the through hole (H) by each mesh sheet (31, 32) and, with the progress of the injection of the sealant material, the air present in the through hole (H) is purged out through each mesh sheet (31, 32).

Description

technical field [0001] The invention relates to a casing structure of a refrigeration device and a sealing method for the casing thereof, in particular to a method for improving the airtightness of the sealing. Background technique [0002] Conventionally, the refrigerated container used for marine transportation etc. is well-known (for example, refer patent document 1). Such a refrigerated container includes a box body for a container having a cargo compartment inside, and a refrigeration device for cooling the cargo compartment. [0003] The refrigerating apparatus includes a refrigerant circuit formed by connecting a compressor, a condenser, and an evaporator through refrigerant pipes, and an adiabatic casing that separates the cargo compartment (inside) of the container body from the outside. The above-mentioned compressor, condenser, etc. are arranged outside the casing, and the evaporator, etc. are arranged on the cargo side (inside) of the casing, and the refrigerant...
