Title: COOLING SYSTEM OF OUTDOOR INFORMATION DISPLAY DEVICE
Abstract:
The present invention relates to a cooling system of an outdoor information display device, the cooling system comprising: a protective cover; a display panel; an inlet through which outside air flows in; an outlet from which inner air is discharged; a first circulation fan, installed under a space area located between the protective cover and a front surface portion of the display panel, for circulating the outside air through the space area; a second circulation fan for circulating the outside air through a rear surface portion of the display panel; a discharge fan for discharging circulated inner air; a temperature detection unit for detecting an inner temperature; and a control unit for controlling the operations of the first circulation fan, the second circulation fan and the discharge fan according to the inner temperature. Accordingly, the present invention can stably operate even in a high-temperature environment through efficient heat discharge, and prevent a possible device breakdown due to the inflow of water such as rain, the inflow of foreign substances such as dirt or the like.
