The invention discloses an electric appliance box and an air conditioner. The electric appliance box comprises a box body, a plurality of first ribs which are arranged on the box body at intervals, wherein a heat exchange channel is formed between every two adjacent first ribs; the second ribs which are arranged on the box body and can move along the surface of the box body, wherein the positionsof the second ribs correspond to the positions of the heat exchange channels, and the second ribs can be partially or completely located in the heat exchange channels in the moving process; and a driving device which comprises a screw rod, wherein the screw rod is in driving connection with the second ribs. According to the electric appliance box, the screw rod is in driving connection with the second ribs, and the second ribs can be driven to move through the screw rod, so that the first ribs and the second ribs partially or completely coincide, the heat exchange area is changed, and the heatdissipation effect is adjusted.

The invention discloses a device for controlling a heating temperature field to purify and prepare polycrystalline silicon. The furnace body is provided therein with a heat insulation plate, a coolingplate, a crucible, a heating induction ring and a heat preservation tube. The heat preservation tube is provided therein with an upper graphite heating ring, a middle graphite heating ring and a lower graphite heating ring, connection rings are arranged between the upper graphite heating ring and the middle graphite heating ring, and between the middle graphite heating ring and the lower graphiteheating ring, respectively, and the connection rings are made from a high temperature resistant material with heat conduction coefficient of 10-50 W / m.k. A purification process comprises the steps: introducing a cooling gas into a cooling plate; introducing an inert gas into a furnace body, and meanwhile discharging through an exhaust pipe provided at the top of the furnace body to ensure a certain gas pressure existing in the furnace body; and controlling the upper graphite heating ring, the middle graphite heating ring, and the lower graphite heating ring to cool according to a certain procedure. The device and process for controlling heating temperature field to purify and prepare polycrystalline silicon facilitates the formation of a uniform temperature gradient, being favorable for crystal growth, and can effectively prevent the stepwise sudden change of a stepwise heat field from top down.
