A control cabinet cooling device (1) includes a housing (2) which comprises a hot air inlet (3) and a cooling air outlet (4), wherein the air to be cooled is suctioned by means of at least one fan (5) in the housing (2) via the hot air inlet (3) into the housing (2), led through an air-refrigerant heat exchanger (6) in the housing (2) and blown out as cooled air via the cooling air outlet (4), wherein a droplet separator (7) is arranged downstream of the air-refrigerant heat exchanger (6) in the air flow direction through the housing (2), wherein at least one lower end (8) of the droplet separator (7) in vertical direction is enclosed by an encapsulation (9) which, on the side thereof facing the droplet separator (7), comprises a condensate collection reservoir (10), into which a condensate discharge (11) of the droplet separator (7) leads.

An air containment system for a datacenter. The air containment system includes horizontally slidable vertical rails that engage the rear rails to two adjacent server racks. The vertical rails can include a front face that is compressible to provide an airtight connection with the server racks. Filler plates attach to adjacent vertical rails and fill the space between a top of the server rack and the top of the rails.

An objective of the present disclosure is to provide a cooling system for a data center. The system includes: a cabinet hot aisle, disposed above a cabinet; a hot airflow passage, disposed at a top of the data center, a ventilating fan being disposed between the hot airflow passage and the cabinet hot aisle; an exterior wall heat exchanging structure, disposed on an exterior wall of the hot airflow passage, a surface of the exterior wall heat exchanging structure adopting a turbulent airflow heat exchanging structure; and a cold airflow passage, communicated with the cabinet, a natural cold air supply damper being disposed between the cold airflow passage and the hot airflow passage.

A modular enclosure includes a plurality of enclosure modules, each of the enclosure modules comprising a front wall, a rear wall opposite the front wall, and two opposed side walls that span the front and rear walls; the front, rear and side walls forming an cavity; an equipment rack within the interior cavity with electronic equipment mounted thereon; and an air containment barrier that extends between the side walls to limit air flow between a front portion of the interior cavity and a rear portion of the interior cavity. At least one of the side walls of each of the enclosure modules includes a removable side panel, the side panel including first and second air flow openings, wherein the first air flow opening is forward of the air containment barrier and the second air flow opening is rearward of the air containment opening. The enclosure modules are arranged in adjacent relationship, and wherein at least one removable side panel of a first enclosure module abuts a removable side panel of a second adjacent enclosure module. The modular enclosure also includes an air cooling system mounted to the side wall of a first endmost enclosure module and an exhaust system mounted to the side wall of an opposite second endmost enclosure module.

An equipment enclosure free air cooling assembly includes an air outlet arranged to deliver air to inside an equipment enclosure and an air inlet arranged to receive air from outside the equipment enclosure. An air flow pathway is provided through which air entering the air inlet must pass to reach the air outlet. An adjustable screen assembly has a screen filter element. An adjustment mechanism is operable to selectively utilize different regions of the screen filter element for filtering air passing through the air flow pathway at different times.

A ventilation closure device for a telecommunication equipment enclosure includes opposed planar panels and aligned openings through each of the panels for passage of air therethrough for ventilating ambient atmospheric air to or from an equipment enclosure. One or more closures are disposed between the opposed panels and adapted to be drawn across the aligned openings for preventing passage of air, and a pivotal attachment to the closures disposes the closure into alignment with the opening. An actuator pivots the closures between an open position for allowing air passage through the openings and a closed position for impeding airflow. The pivotal attachment counterbalances the closures for mitigating force to pivot the closures. Counterbalancing of the closures minimizes actuation force required for drawing the closures across the openings.

An EMP-shielded generator enclosure has a vent coupler, a pair of EMP shieldings, an exhaust vent and an inlet vent. The generator enclosure included a generator receptacle and a generator funnel. The generator funnel funnels hot air out of an interior compartment of the generator enclosure and through the exhaust vent. Specifically, the generator funnel is mounted over an upper opening of the generator enclosure. The exhaust vent is attached to the generator funnel by the vent coupler such that the exhaust vent is placed into fluid communication with the interior compartment through the vent coupler. The inlet vent is mounted onto the generator enclosure and enables air to enter the interior compartment. The EMP shieldings are integrated into the inlet vent and the exhaust vent such that electromagnetic radiation is prevented from entering the interior compartment without hindering the flow of air through the interior compartment.

A central-string inverter device is provided, including a container and multiple string inverters installed in the container. The multiple string inverters are arranged in two rows located respectively on two opposite sides of the container. An intermediate duct is formed between the two rows of string inverters. An air outlet is arranged on each of side walls of the two opposite sides of the container. An air inlet is arranged on each of side walls of the other two opposite sides of the container or on a bottom wall of the container. Pulling structures corresponding to the multiple string inverters are arranged on the side walls of the two opposite sides of the container. Each string inverter is installed or removed through the pulling structure.

A ventilation and air-conditioning system for a room includes a cooling air supply system, a supply air duct system and at least one enclosure. The enclosure includes an inlet, an outlet, and heat storage elements. The ventilation and air-conditioning system is configured such that when the operation of the cooling air supply system fails, a natural convection airflow occurs through the enclosure from the inlet to the outlet, the natural convection airflow being cooled by transferring heat to the heat storage elements. The supply air duct system is arranged above the inlet at a distance from the inlet. A gap is defined between the supply air duct system and the inlet. The inlet of the enclosure is adapted to be in constant flow communication with the room by air flowing from the room through the gap into the inlet of the enclosure.

This application provides a composite cooling system. The composite cooling system includes an indoor air duct and an outdoor air duct that are independent of each other. The indoor air duct and the outdoor air duct intersect in a heat exchange area of the composite cooling system. A first-stage heat exchanger core, a second-stage heat exchanger core, and a first side air duct are disposed in the heat exchange area. The heat exchange area is constructed as a part of the outdoor air duct. The first-stage heat exchanger core, the first side air duct, and the second-stage heat exchanger core are sequentially arranged along a flow direction of the outdoor air duct. An inner cavity of the first-stage heat exchanger core and an inner cavity of the second-stage heat exchanger core each are further constructed as a part of the indoor air duct.
