The reinforcement 30 is made of metal, that is, the reinforcement 30 may be made of reinforced iron or other materials with higher strength, and when the first cover 10 and the second cover 20 are both in an injection-molded structure, the tensile force or the compressive force of the expansion boxes of the two opposite first side walls 201 of the box 200 cannot be borne, and after the reinforcement 30 is made of high-strength materials, the strength of the structure of the middle cross beam 100 is increased, so that the deformation of the box 200 is prevented.
In this embodiment, the second sections 32 are respectively disposed in a pair of hollow heat-insulating cavities of the first side walls 201, and the heat-insulating cavities are disposed with first heat-insulating structures 2013, specifically, after the foaming material is foamed, the foaming material is tightly connected with the second sections 32; in fig. 4 and 5, after the foaming material is foamed, the contact area between the reinforcing member 30 of the middle cross member 100 and the foaming material is increased in the longitudinal direction of the box 200, and the generated adhesion force is also large, so that the reinforcing member 30 is supported;
in addition, the second section 32 may be fixed on the case 2011 or the liner 2012, and the first heat-preserving structure 2013 and the stiffener 30 are connected together to serve the purpose of pulling the first sidewall 201 to prevent deformation when the case is expanded, and the fixing manner of the second section 32 and the case 2011 or the liner 2012 includes screw connection or clip 11 connection, etc.
After the first cover 10 and the frame 203 of the middle cross member 100 are connected by any one or more modes of adhesive, screw structure, buckle 11, welding and injection molding, the reinforcement 30 and the second cover 20 are assembled below the first cover 10.
Further, the embodiment also provides a processing method of the refrigeration device, which comprises the following steps:
providing a case 200, the case 200 including a pair of first sidewalls 201 disposed opposite to each other in a first direction, and an accommodating space formed between the pair of first sidewalls 201, the first sidewalls 201 having a hollow insulation cavity;
providing a middle cross member 100, the middle cross member 100 comprising a cover and a reinforcement 30 extending lengthwise;
the middle cross beam 100 and the box body 200 are assembled and connected, so that the two longitudinal ends of the cover body and the reinforcement 30 are respectively connected with a pair of first side walls 201 in a one-to-one correspondence manner;
the first insulating structure 2013 is formed by foaming within the insulating cavity.
Specifically, after the center sill 100 with the reinforcement 30 and the first side wall 201 are assembled in place, the refrigeration unit is foamed; the connection between the middle cross beam 100 and the first side wall 201 comprises the connection between the cover body and the first side wall 201 and the connection between the reinforcement 30 and the first side wall 201, and the connection between the cover body and the first side wall 201 is achieved by any one or more modes of bonding agent, screw structure, buckle 11, welding and injection molding; the connection between the reinforcement 30 and the first side wall 201 may be that the first heat insulation structure 2013 is connected to the reinforcement 30, or that the reinforcement 30 is connected to the case 2011 or the inner container 2012 of the first side wall 201, and in the foaming process, the reinforcement 30 of the middle cross beam 100 generates a tensile force on a pair of first side walls 201 of the case 200, so as to avoid or reduce deformation generated by expansion of the case 200, and prevent the problem of case expansion during foaming.
In addition, in this embodiment, the reinforcement 30 includes second sections 32 extending longitudinally at two ends, and the two second sections 32 are inserted into the heat insulation cavities of the pair of first side walls 201, and the reinforcement 30 adopts the aforementioned i-shaped structures of the first sections 31 and the second sections 32, that is, the contact area between the middle cross beam 100 and the foaming material is increased, and during the foaming process, the foaming material gradually expands, and the two second sections 32 at two ends of the first section 31 are subjected to pulling force, so as to form a dynamic balance effect; when the foaming speeds of the positions of the second sections 32 at the two sides are different, that is, when the tension of the expansion tank at one side is too large, the total length of the reinforcement member 30 is fixed and cannot be changed due to the too large tension force at one side, the middle cross beam 100 generates tensile deformation, the first section 31 has friction resistance for limiting the outward movement of the second sections 32 at the two ends in the assembly cavity, and after the first heat preservation structure 2013 is foamed, the first heat preservation structure 2013 is tightly connected with the second section 32, so that the possibility of subsequent expansion tank is prevented.

assembling the reinforcement 30 and the second cover 20 with the first cover 10 one by one;
the rim 203 and the first cover 10 are assembled with the body.
It should be noted that the above steps are in parallel relationship, for example, the first cover 10 and the frame 203 may be fixedly connected, then the reinforcement member 30 and the second cover 20 are assembled with the first cover 10 one by one, and finally the frame 203 and the first cover 10 are assembled with the body; the first cover 10 and the frame 203 may be fixedly connected, the frame 203 and the first cover 10 may be assembled with the body, and the reinforcement 30 and the second cover 20 may be assembled with the first cover 10 one by one.
