[0029] refer to Figure 3 As shown, based on the above structure, the outer wall of the small-capacity thermal insulation box 18 can be provided with a second installation slot 19 and a second clamping slot 20, and it can be known that the number of installations of the refrigeration assembly 7 is one group.

[0030] And when the box is relatively small, only a single refrigeration assembly 7 needs to be installed, and the refrigeration assembly 7 can be directly installed on the box, and the stability of the installation is ensured by connecting the fixing buckle 8 with the second card slot 20, and then the operation can be started. Example

[0031] See also Figure 1 As shown, what is different from Example 1 is that the volume of the large-capacity insulation box 1 is different from that of the small-capacity insulation box 18, and the outer wall of the large-capacity insulation box 1 can be connected to multiple groups of refrigeration components 7 through the setting of multiple installation grooves 3 and card slots 4 through fixed buckles 8.

[0032] When the box is relatively large, a single refrigeration component 7 is difficult to meet the cooling demand, that is, a plurality of installation slots 3 and card slots 4 can be opened on the outer wall of the large-capacity thermal insulation box 1 according to the needs, and cold air duct channels 5 and cold air duct outlets 6 are installed accordingly, and then the refrigeration component 7 is installed on each installation slot 3 to complete the installation and use.

[0033] It should be understood that the size and capacity of the box in the above description only represents the variable capacity, rather than specifically limiting the size of the thermal insulation box, and in fact, it can be designed to any capacity.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
