The invention relates to an active cooling air inlet channel mounting structure. The structure comprises a machine body and an air inlet channel. The machine body comprises a machine main body and a machine body rear part. The air inlet channel is located at one side of the machine main body, the rear end of the air inlet channel is fixed to the machine body rear part, a side flange is arranged at the side edge of the air inlet channel, a boss is arranged on the side flange and extends in the length direction of the air inlet channel, a first groove is formed at the contact position of the machine main body and the side flange, the boss can be inserted into the first groove, the side flange is attached to the machine main body, and the width of the first groove is larger than that of the boss, so that when the air inlet channel is at a high temperature, the air inlet channel can deform and move in the length direction and the width direction of the first groove after being heated, the air inlet channel can adapt to thermal deformation matching when installed on the machine body, a labyrinth sealing structure can be formed after the boss and the first groove are tightly attached, and the thermal sealing reliability of the air inlet channel installed on the machine body is guaranteed.

    本发明涉及一种主动冷却进气道安装结构,其包括:机身,其包括机身本体和机身后部;进气道,其位于所述机身本体的一侧,所述进气道的后端与所述机身后部固定,所述进气道的侧边具有侧边法兰,所述侧边法兰上设有凸台,且所述凸台沿所述进气道的长度方向延伸,所述机身本体与所述侧边法兰接触处设有第一凹槽,所述凸台可插入所述第一凹槽内,且所述侧边法兰与所述机身本体贴合,所述第一凹槽的宽度大于所述凸台的宽度,因此,当进气道在高温下时,进气道受热可以沿第一凹槽的长度方向和宽度方向变形移动,进气道安装于机身时可以适应热变形匹配,凸台与第一凹槽紧密贴合后可以形成迷宫密封结构,保证进气道安装于机身的热密封可靠性。
