With continued reference to fig. 2, the modular refrigeration unit 3 is inserted into the installation space 12 via the open right side 121. And when the modular refrigeration unit 3 is located in the installation cavity 12, a part of the foaming box body 1 surrounds the outside of a part of the modular refrigeration unit 3, and the right side wall surface of the cabinet 31 forms a part of the outer contour surface of the horizontal air-cooled refrigerator 100.

In order to enable the modular refrigeration unit 3, which is inserted into the installation cavity 12, to be fixedly engaged with the cabinet 1. A connecting mechanism 4 is arranged between the modular refrigeration unit 3 and the box body 1. In this case, for the sake of simple assembly, the connection mechanism 4 comprises a plurality of movable screw locking pieces 41 and threaded holes (not shown in the figures) arranged on the joint 13 of the cabinet 31 and the foaming cabinet 1 of the modular refrigeration unit 3, and the user can easily connect or disconnect the modular refrigeration unit 3 and the cabinet 1 to or from each other by screwing in and unscrewing the screw locking pieces 41. In other embodiments, the connecting mechanism may also be a quick release mechanism that facilitates assembly.

When the modular refrigeration unit 3 is fixedly connected to the cabinet 1, the engaging portion 13 is located directly above the modular refrigeration unit 3 and the engaging portion 13 presses the cabinet 31 downward, the first opening 361 is in sealing engagement with the first port 23, the second opening 362 is in sealing engagement with the second port 24, and the plurality of screw locking members 41 securely lock the engaging portion 13 to the top of the cabinet 31. The plurality of support wheels 301 at the bottom of the modular refrigeration unit 3 can be supported directly on the ground; furthermore, since the compartment 11 stores the goods, the self-weight of the box 1 can press the joint 13 toward the cabinet 31 of the modular refrigeration unit 3, so that the modular refrigeration unit 3 and the box 1 are firmly combined, and the first opening 361 and the first interface 23 and the second opening 362 and the second interface 24 are firmly kept in the sealing connection state. Starting the refrigerating unit, under the action of the evaporator fan 35, cold air flows out from the first opening 361, enters the air supply duct 22 through the first interface 23, and is sent into the compartment 11 through the air supply outlet 26; because the air supply duct 22 has a long length and a large resistance, the air supply mode can ensure the air output of the cold air flowing out from the air supply opening 26. As the cold air is continuously sent into the compartment 11, part of the air flow enters the return air duct 25 from the return air inlet 27 and enters the heat exchange chamber 36 through the second connector 24 and the second opening 362 for cooling again, and because the return air duct 25 is short in length and low in resistance, the air flow flowing into the return air duct 25 can easily enter the heat exchange chamber 36 from the second connector 24 and the second opening 362; the air flow cooled in the heat exchange chamber 36 is sent to the compartment 11 again by the air supply duct 22 under the action of the evaporator fan 35, and is thus circulated.

In conclusion, the modular refrigerating unit is of a detachable structure, so that maintenance of the refrigerator is facilitated for maintenance personnel, and a manufacturer can design the modular refrigerating unit into a universal standard component to be assembled on refrigerator bodies of different specifications for use.
