It will be appreciated that the weld windows 34 are located at the edge of the first cover plate 21 adjacent the first opening and the refrigerated return vents 30 are located at the lower portion of the second cover plate 22. In this case, the first compartment 14 is a freezing compartment, and the second compartment 15 is a temperature-variable compartment. Of course, the position of the freezing return air inlet 30 is not limited to this, and the freezing return air inlet 30 may be provided in the second cover 22, in which case the first compartment 14 is a variable temperature compartment and the second compartment 15 is a freezing compartment.

It can be understood that the side of the air duct member 20 is detachably connected to the inner wall of the tank body 10 by a plurality of connecting members.

It can be understood that, in order to effectively fix the air duct member 20, the side of the vacuum insulation panel cover plate 24 is connected to the inner wall of the tank body 10 by a plurality of knobs, and the side of the vacuum insulation panel cover plate 35 can be conveniently and rapidly connected to the inner wall of the tank body 10 by using the knobs. Because the side of the vacuum heat insulation cover plate 35 is connected with the inner wall of the box liner body 10 through the foaming material and also connected through the knob, the air duct component 20 is fixed by adopting two modes to cooperate together, and the stability of the air duct component 20 is effectively improved. Of course, screws or fasteners may be used to connect the side edge of the vacuum insulation cover plate 35 with the inner wall of the tank body 10.

The utility model also provides a refrigeration plant, including casing, case courage subassembly and the arbitrary one of the above-mentioned embodiment the wind channel part, case courage subassembly set up in the casing, case courage subassembly includes the case courage body. According to the utility model discloses refrigeration plant through using above-mentioned wind channel part, has simplified refrigeration plant's installation procedure, has improved production efficiency, has reduced the human cost, has strengthened product competitiveness.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications or substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
