Abstract

PURPOSE:To obtain a simple and effective forced cooling system for preventing dust from accumulating by providing a means for varying a direction of moving a cooling medium, and varying the direction of flow of the refrigerant at an interval of predetermined time. CONSTITUTION:In a forced cooler having a mechanism for moving a cooling refrigerant, a means for varying the moving direction of the refrigerant is provided to vary the moving direction of the refrigerant at an internal of a predetermined time to disturb the accumulation of dust contained in the refrigerant at a predetermined position, thereby preventing cooling effect from decreasing. For example, a predetermined time lapse switching controller 7 switches a switch 8 in a fan power source switch 5 by information of a timer 9, thereby switching the power supply from a fan power source 6 from a left side fan 3L to a right side fan 3R. In this case, dust accumulated on a right side filter 4R is scattered by a forced reverse wind of stronger wind power than that of seminatural wind at the time of the accumulation. Thus, the two fans are alternately used.
