Therefore, the condenser can be substantially brought into contact with the lower surface of the front end of the outer box or the heat transfer member only by assembling the duct to the outer box, so that the operability of assembling the condenser is improved. According to the fourth aspect of the present invention, the condenser pipe is arranged substantially parallel to the front plate below the outer box. For this reason, the amount of heat transfer from the capacitor to the outer box is increased, so that the front plate below the outer box is easily heated to the dew-prevention temperature.

According to the fifth aspect, the pipe of the condenser is substantially brought into contact with the lower surface of the front end of the outer case or the heat transfer member. For this reason, the amount of heat transfer from the capacitor to the outer box is increased, so that the front plate below the outer box is easily heated to the dew-prevention temperature. According to the measure described in claim 6, the condenser is arranged in an upwardly inclined shape. For this reason, since the wind is efficiently blown to the capacitor, the heat radiation performance of the capacitor is improved.

According to the seventh aspect of the present invention, the enlarged heat transfer portion of the capacitor is substantially brought into contact with the lower surface of the front end of the outer box or the heat transfer member. For this reason, it is possible to cope only by bending the small-diameter enlarged heat transfer portion such as a wire, so that the degree of freedom of arrangement of the capacitor is increased.
