LASER APPARATUS INCLUDING HEAT TRANSFER DEVICE RELEASING HEAT INSIDE HOUSING TO OUTSIDE

摘要

To provide a laser device that controls a device such that the humidity of a space inside a housing is within an appropriate range.SOLUTION: A laser device 1 includes a heat transfer device 8 having a cooling fin 22 having a temperature lower than that of a heat dissipation jacket 23 and a cooling fan 13. A control device 7 controls the cooling fan to stop when the temperature detected by a temperature sensor 31 is lower than a temperature reference value and the humidity detected by a humidity sensor 41 is higher than a humidity reference value. The control device 7 controls the cooling fan 13 to drive when the temperature detected by the temperature sensor 31 is higher than the temperature reference value and the humidity detected by the humidity sensor 41 is lower than the humidity reference value.SELECTED DRAWING: Figure 1
