The device includes a control means for application of a high voltage applied through a transformer, or the like, the same contained in the space chamber. The invention is characterized in that the interior of the space chamber is separated by at least one partition wall into a front chamber for containing the control means and a rear chamber for containing the high voltage element. A cooling fan is in communication at its intake side with the interior of the rear chamber, and the forward end of the cooling duct is open to the exhaust opening.
