Each first pipe intended to be connected to a corresponding air-circulation opening of a compartment, and the second pipe being intended to be connected to an air-circulation means in order thus to allow air to be circulated in the plurality of compartments. A cabinet is provided with such a protection device.

Described herein is a ventilation device for admitting air ventilation of a cabinet and preventing liquid passing from outside to inside of the cabinet, the ventilation device comprises a casing capable of being mounted in front of at least one cabinet opening of a cabinet, where the casing comprises at least one casing opening, a tube with a collar, where the tube is mounted on the casing and covering the at least one casing opening, and a cap covering the collar and leaving distance between the cap and the collar making it capable for air to pass between the cap and the collar.

A battery charger for electric or hybrid motor vehicles having one container body installable on a motor vehicle and defining one housing compartment, one electronic appliance housed inside the housing compartment, connectable to one electric battery of the motor vehicle and configured to recharge the battery, one closing body of the container body associated in a removable manner with the latter to close the housing compartment, and the closing body being adapted to protect the electronic appliance housed inside the housing compartment whereby the closing body includes a reinforcing device/structure/component which are shaped and arranged so as to prevent the deformation of the closing body itself.

A housing for electronic components within a vehicle, the housing comprising: a main compartment adapted to house one or more electronic components; and a venting arrangement to allow a gas flow path between an interior of the main compartment and the exterior of the main compartment, wherein the venting arrangement comprises: a shield portion positioned on the exterior of the main compartment and defining a flow pathway having first and second apertures at respective first and second ends thereof, at which the flow pathway is in communication with the atmosphere; and a communication passage extending between the interior of the main compartment and the flow pathway, and joining the flow pathway at a position between the first and second ends thereof, wherein the communication passage meets the flow pathway at a point which is nearer to the first end than the second end.

An example computing device may include a housing having an outer panel, the outer panel comprising a first array of openings through the outer panel, an inner panel opposite the outer panel, the inner panel comprising a second array of openings and a third array of openings different than the second array of openings and an actuator to move the inner panel relative to the outer panel between (1) a first position in which the second array of openings are at least partially aligned with the first array of openings and the third array of openings are out of alignment with the first array of openings, and (2) a second position in which the third array of openings are at least partially aligned with the first array of openings and the second array of openings are out of alignment with the first array of openings.

Provided is an electrical junction box that enables suppression of entry of water even when the electrical junction box is installed in a vehicle in different orientations. Disclosed is an electrical junction box including a first case having an opening, a second case configured to cover the opening, and an accommodated component that includes a circuit assembly and is housed between the first case and the second case. The second case includes a peripheral wall formed by connecting a plurality of flat faces in a polygonal shape to cover an outer periphery of the first case adjacent to the opening. The first case includes water guard walls extending along at least two of the flat faces to cover a region not covered with the peripheral wall.

A vent filter and a Radio Remote Unit having the vent filter. The vent filter includes a first member including a first body having a ventilation path extending through the first body, an inner wall constituting a ventilation hole which is communicated with the ventilation path, and an outer wall constituting a gap between the inner wall and the outer wall. The vent filter also includes a second member including a second body and at least one enclosure wall protruding out from the second body, wherein at least one of the at least one enclosure wall is located outside the outer wall and surrounding the outer wall. Both the inner and outer walls have at least one first groove at an end and each of the at least one enclosure wall has at least one second groove at an end.

An outer case includes an upper case, a lower case, and a plurality of guiding structures. The lower case includes a bottom wall defining a plurality of through holes. The guiding structures are arranged on the bottom wall. Each of the guiding structures includes a first guiding plate and a second guiding plate, the first guiding plate includes a first connecting part and a first blocking part connected with the first connecting part, the second guiding plate includes a second connecting part and a second blocking part connected with the second connecting part, the first connecting part and the second connecting part face each other. The first blocking part is suspended on the bottom wall through the first connecting part, the second blocking part is suspended on the bottom wall through the second connecting part, the first blocking part and the second blocking part are staggered.

A passive cooling system routes air from an enclosure to an ambient environment, via a chimney effect, through one or more indirect pathways and re-directs environmental elements received from the ambient environment. One or more vanes are arranged within an interior space, such that the vanes collectively form one or more indirect pathways to the ambient environment. The vanes preclude environmental elements, including precipitation and particulate matter, from passing through the interior space and into the enclosure. Environmental elements are re-directed by one or more of the vanes, at least in part, to an exterior of the passive exhaust system. Dampers may be adjusted to control airflow through the passive cooling system and restrict environmental elements from entering the passive cooling system. Liquids received from the ambient environment may be re-directed into a reclamation system for use in a cooling system.
