The invention relates to a power converter for outdoor use comprising at least a first cabinet having an air inlet (1) and a second cabinet having an air outlet (2) that surround a cell cabinet (3) having a plurality of power cells (3a) and a transformer cabinet (4) with at least one power transformer (4a); and wherein the air inlet (1) comprises a sand trap (5); a cold air stream (9) from outside the converter passes from the air inlet (1) to the cells (3a) and the transformer (4a) through a cyclonic air filter (6) comprising a tubular duct with an inner geometry formed by helical-shaped blades; and wherein a warm air stream (10) from the cells (3a) and the transformer (4a) is expelled through the air outlet (2).

A central-suing 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 suing inverters are arranged on the side walls of the two opposite sides of the container. Each suing inverter is installed or removed through the pulling structure.

A cooling device includes a fan for blowing air to a control board arranged on the downstream side by rotation of a rotator. The cooling device further includes a bypass structure provided so as to avoid the rotator and configured to oil liquid to flow, at least, from the upstream side of the fan to the downstream side of the fan, and a gutter provided on the upstream side of the fan to lead the oil liquid to the bypass structure.

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.

There is provided a power converter unit that can include an inverter and a plurality of batteries. The power converter unit can include a battery energy storage system (BESS) and an inverter. The BESS and the inverter can share at least one protection circuit.

A data center includes heat producing components and an air handling system that provides reduced relative humidity air to cool the heat producing components. The air handling system includes a thermal storage unit that removes thermal energy from incoming air under a given set of ambient air conditions and releases thermal energy into incoming air under another set of ambient air conditions. Under the given set of ambient air conditions, the thermal storage unit cools the incoming air and causes water vapor to condense out of the incoming air. Under the other set of ambient air conditions, the thermal storage unit releases thermal energy into the incoming air, thus heating the incoming air.

An air extraction unit taking the form of a body, the geometric shape of which makes it easier to incorporate into an avionics bay of an aircraft. The air extraction unit derives from a multipurpose approach to the operational components of the avionics bay of an aircraft aimed at achieving weight and cost savings. All of the elements of the air extraction circuit are arranged in a compact housing of the body and are protected by the structure thereof. The air extraction unit can be used as a floor of an avionics bay that can be walked on, with a lateral organization.

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.

According to one embodiment, an electrical equipment housing includes a first storage room, an air conditioner, a second storage room, a temperature sensor, and a heater. The first storage room contains a power converter converting electrical power. The air conditioner adjusts a temperature inside the first storage room. The air conditioner includes an indoor unit and an outdoor unit. The indoor unit is provided inside the first storage room. The outdoor unit is provided outside the first storage room. The second storage room contains the outdoor unit. The temperature sensor senses a temperature inside the second storage room. The heater heats inside the second storage room when the temperature sensed by the temperature sensor is a lower limit or less.
