Based on the above, the invention has at least the following technical effects or advantages:
according to the invention, the shell 100 with the air duct 190 is arranged, and meanwhile, the shell 100, the evaporator 200 and the fan 300 are integrated together to form an independent refrigeration module, so that when the fan 300 operates, air in the commercial refrigerator body flows along the air duct 190, heat exchange between the air and the evaporator 200 is changed into forced convection, circulation flow efficiency of air quantity in the commercial refrigerator body 10 is promoted, and meanwhile, wind resistance when the circulating air in the refrigerator body 10 passes through the evaporator 200 is greatly reduced, so that the technical problem of how to improve the circulation efficiency of the air quantity in the commercial refrigerator body is solved, and further, the air quantity is enabled to efficiently bring cold quantity obtained from the evaporator into a cavity of the refrigerator body, so that the refrigeration efficiency of the commercial refrigerator is greatly improved, and a low-temperature environment in the refrigerator body can be well maintained.
In addition, the invention enables the air circulation inside the cabinet body 10 to be smooth, thus compared with the prior art, the invention reduces wind resistance and greatly reduces noise and energy consumption generated by air circulation.
In order to further improve the circulation efficiency of the air inside the cabinet 10, as shown in fig. 1, in the air circulation direction along the air, the air channel section of the first air channel portion is sequentially reduced, that is, the first air channel portion is gradually thinned, so that the air is gradually extruded in the process of circulating along the first air channel portion, thereby accelerating the output speed of the air from the air outlet 192, enabling the air to be more intensively output from the air outlet 192, that is, improving the supply of the effective air inside the cabinet 10, and further improving the circulation efficiency of the air inside the cabinet 10; similarly, the air duct section of the second air duct part can be larger than that of the first air duct part, namely, the second air duct part is thicker than the first air duct part, so that the circulation efficiency of air in the cabinet body 10 is better improved; further, in the flow direction along the wind, the air channel section of the second air channel portion is sequentially reduced, so that the circulation efficiency of the air inside the cabinet body 10 is better improved, and meanwhile, the wind is enabled to be concentrated and contacted with the evaporator 200, and further the heat exchange efficiency is improved.
It should be further noted that, when the product inside the cabinet 10 is frosted, the evaporator 200 is at a high temperature, and the high temperature of the evaporator 200 cannot be effectively prevented from penetrating into the product in the prior art, so that the temperature of the storage area inside the cabinet 10 is increased, and frosting or even freezing point is formed inside the cabinet 10 and on the stored articles. Based on this, the present invention can effectively isolate the evaporator 200 by providing the housing 100 having the air duct 190 and integrating the housing 100 with the evaporator 200 and the blower 300 together to form an independent refrigerating module, so that the high temperature of the evaporator 200 is difficult to penetrate into the storage article area in the cabinet 10, thereby effectively slowing down the temperature rise of the stored articles in the cabinet 10, and therefore, the present invention can also solve the technical problem that frost and even freezing point are easily formed in and on the commercial refrigerator 10, thereby better avoiding the occurrence of the phenomenon that frost and even freezing point are formed in and on the commercial refrigerator 10, and simultaneously improving the refrigerating efficiency of the commercial refrigerator.
In order to further slow down the temperature rise of the stored articles in the cabinet 10, the casing 100 is made of a heat insulation material, specifically, the casing 100 is preferably a foam casing, so that the casing 100 has low heat conductivity, on one hand, the casing 100 is convenient to mold and process, for example, foam casings with various shapes are made by means of bonding by an adhesive or bonding with other materials, and meanwhile, the basic structural strength can be realized, on the other hand, the evaporator 200 is better isolated from the area of the stored articles in the cabinet 10, the high Wen Chuanru of the evaporator 200 is better avoided from reaching the area of the stored articles in the cabinet 10, and the temperature rise of the stored articles in the cabinet 10 is further more effectively slowed down.
In addition, by providing the housing 100 as a foam housing, noise from the blower 300 and the like can be absorbed when the commercial refrigerator is used, thereby reducing noise interference.

For a clearer description of the present invention, the installation and operation of the refrigeration system of the present invention will be described with reference to the embodiments shown in fig. 1 to 4:
the evaporator 200 is fixedly connected with the wall of the cabinet 10 through bolts, the shell 100 is sleeved outside the evaporator 200, so that the air duct 190 corresponds to the heat exchange unit 210, convection efficiency is guaranteed, the supporting plate 400 is installed below the shell 100, the fan 300 is installed on the supporting plate 400 through bolts and is arranged corresponding to the air inlet 191, the supporting plate 400 is fixedly connected with the wall of the cabinet 10 through bolts, and meanwhile, the supporting plate 400 is extruded with the shell 100 to support the shell 100.
When the evaporator 200 and the blower 300 start to work, the rotation of the blower 300 causes the air flow in the cabinet 10 to be performed along the air duct 190, that is, the air enters the air duct 190 from the air inlet 191, after contacting with the evaporator 200 along the air duct 190, the air is output from the air outlet 192 to the storage space outside the air duct 190, then the air is sucked by the blower 300 from the storage space after contacting with the stored articles and exchanging heat, and flows back to the air inlet 191, so that the reciprocating circulation is performed, wherein the arrangement of the air duct 190 and the rotation of the blower 300 promote the flow circulation of the air in the cabinet 10, accelerate the refrigerating speed, and further improve the refrigerating efficiency.
Example two
The difference from the first embodiment is that, referring to fig. 5 and 6, the present embodiment adopts a split design for the housing 100, so that the structural design can be more flexible:
the housing 100 includes a first housing portion 148 and a second housing portion 149, the first housing portion 148 and the second housing portion 149 are detachably connected (fastened, clamped or glued), and the air duct 190 is formed between the first housing portion 148 and the second housing portion 149, as shown in fig. 5 and 6, and the first housing portion 148 and the second housing portion 149 are disposed in a front-back spliced manner in this embodiment, that is, the first housing portion 148 is located in front of the second housing portion 149 (corresponding to fig. 1).
Example III
The difference from the second embodiment is that, as shown in fig. 7 and 8, the first housing portion 148 and the second housing portion 149 are disposed in a vertically spliced manner in this embodiment, i.e., the first housing portion 148 is located above the second housing portion 149 (corresponding to fig. 1).
