As a result, the inflow of air from the outside into the electronic device 31 is prevented, and the reversible moisture absorbent 35 activated and recovered from the residual air in the device absorbs moisture. As a result, dew condensation in the electronic device 31 is prevented.
- the above-described conventional device has a configuration for reducing the humidity inside the electronic device and preventing dew condensation, it uses a reversible hygroscopic material that is dried and regenerated at a predetermined temperature or higher. If the temperature does not exceed a predetermined temperature, the reversible moisture absorbent does not dry and regenerate, and the humidity rises. If the power is repeatedly turned on and off in order to dry and regenerate the reversible absorbent material, the most important operations on the equipment will be involved, which will cause problems in the operability of the equipment and will also cause problems with the closing plate. Opening and closing operations need to be performed frequently.
- An object of the present invention is to provide a cooling device capable of preventing a corrosion in an electronic device and recovering a dehumidifying function irrespective of ON / OFF of a power supply of the device.
- a cooling device of the present invention is provided on an outside air suction side and an air exhaust side of a housing of a device, respectively, for removing humidity of outside air, and a set of dehumidification means having a filtering member, A dehumidifying function recovering means for recovering the dehumidifying function of the dehumidifying means when the humidity in the housing reaches a saturated state.
- a fan that ventilates outside air into the housing to cool the heating element is installed in the housing between a pair of dehumidifying means and facing them.
- the dehumidifier as a dehumidifier receives the heated and dried exhaust from the heating element and releases the accumulated moisture to the outside, so that the dehumidifier's ability to absorb moisture is independent of the power on / off of the equipment. Recover. Therefore, there is no need to replace the dehumidifier due to moisture absorption.
- the cooling device of the present invention also has a heat protection function.
- Figure 1 is a front view showing the structure of a conventional cooling device for electronic equipment
- FIG. 2 is a cross-sectional view showing a configuration of a cooling device for an electronic device according to an embodiment of the present invention, and a flow direction of outside air before a moisture absorbing capacity of a dehumidifying material reaches a saturated state;
- FIG. 3 is a cross-sectional view showing the direction of the flow of outside air after the moisture absorbing capacity of the dehumidifying material has reached a saturated state in the electronic device cooling device of FIG.
