The utility model relates to a heat radiating air channel, comprising a blower fan. Further comprised are a collection area, an amplification area, and an output area which are sequentially communicated, wherein the collection area is arranged inside a cabinet body; the three areas mentioned above form a communicated area, where the large majority of the blower fan is arranged; and the cross section area of the amplification area vertical to the blower fan axis is greater than that of the collection area. As the large part of the blower fan is arranged in the communicated area formed by the collection area, the amplification area, and the output area, the size of the cabinet body is reduced, thereby facilitating installation and maintenance. With the adoption of three layers of air channels, the length of the air channel of the collection area having relatively small cross section is decreased, and the cross section area of the amplification area vertical to the blower fan axis is greater than that of the col
