The at least one preset condition includes at least one of or more of the following cases: the inverter is running, humidity in the cabinet compartment is higher than preset humidity, and a temperature in the cabinet compartment is higher than a preset temperature.

A method for environmentally managing a computing device of an information handling system includes monitoring an environmental corrosion risk associated with a component of the computing device, a corrosion management component that reduces a rate of corrosion of the component due to an ambient environment in which the component resides by removing condensation from the component is associated with the component; making a determination that the component is associated with the corrosion management component; in response to the determination: estimating a corrosion risk of the component based on: the environmental corrosion risk, and a risk reduction factor associated with the corrosion management component; making a second determination that the corrosion risk of the component indicates a premature failure of the component; and remediating, in response to the second determination, the corrosion risk of the component.

A telecommunications cabinet (100) for enclosing telecommunications equipment (110) of a telecommunications network, the telecommunications cabinet comprising: an electric water pump (140); a water detector (160), wherein the water detector is configured to cause activation of the electric water pump upon detecting water; a power supply (150) for powering the electric water pump; and a fluid conduit (170), coupled to the electric water pump, extending from within the cabinet to an outside of the cabinet via an aperture (180) in the cabinet so as to convey water out of the cabinet.

A data center humidification system can include a housing configured to be mounted within a server cabinet, the housing having an inlet for receiving warm air and an outlet for ejecting humid air, a wetted media within the housing proximate to the inlet, a liquid delivery pipe at least partially within the housing and configured to deliver liquid to the wetted media, at least one outlet droplet trapping media within the housing proximate to the outlet, and at least one fan configured to move air through the housing.

An electronic apparatus includes a housing with a power supply unit that receives external electrical power and supplies it to the apparatus using a power controller. The housing includes a heater; temperature and humidity sensors; and an electronic processor that receives power from the power supply unit and controls functions of the electronic apparatus. Upon startup, the power controller receives data from the temperature and humidity sensors; processes the received temperature and humidity data to indicate a current dew point within the housing; and compares the current dew point with a current location temperature at a location within the housing. If the current location temperature is at or below the current dew point, the heater is activated to raise the temperature within the housing. If the current location temperature is above the current dew point, electrical power supplied from the power supply unit to the electronic processor.

An information handling system includes a computing device, a computing component of the computing device that is housed in a chassis, and a chilled air filter that reduces a humidity level of a portion of an airflow when the chilled air filter is in an active state. The portion of the airflow thermally manages the computing component. The airflow is received by the chassis via an air receiving exchange and exhausted by the chassis via an air expelling exchange.

The disclosure relates to a condensate draining device for discharging condensate from at least one cooled component, which is in particular a cooled electronic system and has a surface on which condensate formation can occur, wherein the condensate draining device has a heat conducting element which has a condensation surface and which is designed to at least partially cover the surface of the at least one component and to transfer a cold causing condensation on the surface of the at least one component to the condensation surface, further having a housing with at least one condensate drain and/or a condensate chamber for collecting a condensate forming on the condensation surface, wherein the at least one condensate drain determines in each case at least one predetermined flow path which is fluidically separated from the at least one component for draining off the condensate from the housing.

An enclosure system can include an enclosure comprising at least one wall forming a first cavity. The enclosure system can further include a moisture control system in communication with the enclosure, wherein the moisture control system controls at least one condition within the cavity of the enclosure, where the at least one condition affects an amount of moisture within the first cavity. The moisture control system can include a sensor that measures an amount of moisture in desiccant disposed within a desiccant vessel. The moisture control system can include a structural filter and a desiccant vessel, where the structural filter is coupled to an enclosure and disposed within a cavity formed by the enclosure, where the desiccant vessel is removably coupled to the structural filter, and where the desiccant vessel is accessible from outside the enclosure.

An information handling system includes a computing component that is sensitive to corrosion; and a chassis in which the computing component is disposed. The chassis receives an airflow used to thermally manage the computing component, and expels the airflow after thermally managing the computing component. The information handling system also includes an environmental control component that reduces a condensation formation propensity of a portion of the airflow that traverses the chassis proximate to the computing component.

A water intrusion mitigation device for use in enclosures housing electric components and equipment that are sensitive to humidity includes a thermoelectric cooler and a water electrolyzer. The thermoelectric cooler has two sides: a first side that is configured to be heated with the application of an electric current and a second side that is configured to cooled with the application of an electric current. The water electrolyzer is a proton exchange membrane that is in thermal communication with the second side of the thermoelectric cooler.
