The first heat dissipation frame 130 is arranged at the lower end of the upper frame body 100. A first heat dissipation hole 142 is provided at the right end of the upper frame body 100.

[0021] Furthermore, the first heat dissipation frame 130 includes a number of first heat dissipation fins 131. The first heat dissipation fins 131 are arranged in parallel and at equal intervals. The first heat dissipation fins 131 are perpendicular to the first air outlet 124. A number of first connecting bars 132 are provided between the first heat dissipation fins 131.

[0023] Further, a first connection opening is provided at the upper end of the lower frame body 200, and a first connection ring 160 is provided at the lower end of the upper frame body 100. The first connection ring 160 is in interference connection with the first connection opening.

[0024] Further, a plurality of first barbs 161 are provided on the outer side of the first connection ring 160, and a plurality of first hanging holes 210 are provided at the upper end of the lower frame body 200. The first barbs 161 correspond to the first hanging holes 210 one by one.

[0025] Further, a first heat insulation plate 150 is provided at the upper end of the upper frame body 100.
