The specific embodiment of the present utility model is described below, so that those skilled in the art understand the utility model, but should be clear, the utility model is not limited to the scope of specific embodiment, for those of ordinary skill in the art, as long as Various changes are within the spirit and scope of the utility model defined and determined by the appended claims, and these changes are obvious, and all inventions and creations utilizing the concept of the utility model are all included in the protection list.

Referring to FIG. 1 and FIG. 2 , FIG. 1 shows a perspective view of the top-mounted cooling device for communication cabinets, and FIG. 2 shows a perspective view of the top-mounted cooling device for communication cabinets with part of the shell removed.

As shown in Fig. 1 and Fig. 2, the top-mounted cooling device of the communication cabinet includes a cooling device 1 arranged on the top of the communication cabinet 2, and the cooling device 1 includes a refrigerator, a return air duct 14 and an air outlet duct 15; the return air duct 14 Conducted with the air inlet 18 of the heat exchange component of the refrigerator, the return air duct 14 extends out of the bottom plate of the refrigeration device 1; a sealed air guide channel is set at the cold air outlet of the refrigerator, and the air outlet duct 15 communicates with the air guide channel , and extend out of the bottom plate of the refrigeration device 1 .

When in use, a plurality of through holes are provided on the top of the communication cabinet 2, and the cooling device 1 is installed on the top of the communication cabinet 2, so that the return air duct 14 and the air outlet duct 15 extend to the inside of the top of the communication cabinet 2 through the through holes, The return air duct 14 is arranged in the middle or both sides of the communication cabinet 2 through the through hole opened on the communication cabinet 2 , and the air guiding channel is arranged on the door panel side adjacent to the communication cabinet 2 .

The cold air after heat exchange by the heat exchange parts of the refrigerator is sent into the inner side of the door of the communication cabinet 2 through the air outlet duct 15 to form a cold air curtain. The electronic components are cooled, and the gas with higher temperature rises to the top of the communication cabinet 2, and the refrigerator forcibly draws hot air into its interior to complete heat exchange with the heat exchange components.

Considering the production cost and cooling effect of the top-mounted refrigeration device of the communication cabinet, the refrigerator of this solution can directly use the window air conditioner on the market, because the cold air outlet and air inlet 18 of the window air conditioner are arranged on its side, not Any form of air guiding channel can directly blow the cold air into the communication cabinet 2 .
