PROBLEM TO BE SOLVED: To prevent noise generation by changing an arrangement and a shape of each component and further enable change of the arrangement of a noise generation source according to a situation of a site.SOLUTION: A heating element housing box cooling device includes: a first ventilation path 7 provided at a primary side of a condenser 2 viewed from a ventilation direction; a second ventilation path 8 arranged at a secondary side; a first insulating plate 9 and a second insulating plate 10 provided inside the first ventilation path 7 and a third insulating plate 23 and a fourth insulating plate 24 provided inside the second ventilation path 8 at a top surface side and a bottom surface side respectively so that the ventilation direction becomes an S shape; and an outdoor blower 6 arranged between the second insulating plate 10 and the condenser 2 or between the fourth insulating plate 24 and the condenser 2. By such a constitution, noise generated in the outdoor blower 6 is insulated by the first insulating plate 9, the second insulating plate 10, the third insulating plate 23, and the fourth insulating plate 24, thereby the heating element housing box cooling device which prevents the noise from emitting to the outside can be obtained.SELECTED DRAWING: Figure 1 |
