Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] see Figure 4, to introduce an embodiment of the present invention-the structural composition of the circulating cold air device for the high-voltage frequency converter unit cabinet. The device includes four parts: the high-voltage frequency converter unit cabinet 3 that needs to be cooled for the heating components in the cabinet, and the heat exchange cabinet 12 that isolates and cools the hot air through the cold water in the disk-shaped pipeline. The hot air discharged from the high-voltage inverter unit cabinet is sent to the air inlet connection channel 10 of the air inlet of the heat exchange cabinet, and the cold air discharged from the heat exchange cabinet is sent to the air outlet connection channel 11 of the air inlet of the high-voltage invert...
