A server rack cooling arrangement may include a server rack enclosure defining a single undivided interior volume of space and configured to be sealable; two or more open-frame-server-units disposed within the interior volume of space and arranged in a multi-level arrangement, wherein heat-producing-electronic-components may be exposed to environmental conditions of the interior volume of space; a central condenser disposed towards a rear; a coolant reservoir for collecting condensate from the central condenser; at least one nozzle in fluid communication with the coolant reservoir and configured to deliver fine coolant droplets into the interior volume of space for impingement on the heat-producing-electronic-components; and a fan configured to generate an airflow through the two or more open-frame-server-units from a front to the rear in a manner so as to carry coolant vapour generated from impingement of the fine coolant droplets on the heat-producing-electronic-components to the central condenser.

A method of actuating, comprising: filling at least a portion of a tube () with a liquid () containing electrolytes, the tube () having an inner surface that is electrically chargeable when in contact with the liquid (); positioning an object () in fluid communication with the liquid in the tube; and applying an electrical field () along a lengthwise axis across the tube at said portion for producing a pressure in the liquid. The pressure in the liquid exerts a force on the object so as to actuate the object (). An actuator () is also disclosed.

A method and apparatus for controlling multi-fluid flow in a micro channel is disclosed. The apparatus has a first inlet for a first fluid; a second inlet for a second fluid; a first outlet; and a second outlet. The micro channel is operatively and fluidically connected to the first inlet, the second inlet, the first outlet and the second outlet. The micro channel is for receiving the first fluid and the second fluid under pressure-driven flow; there being an interface between the first fluid and the second fluid when in the micro channel. The apparatus also includes a pair of electrodes for having a first electric field applied thereto for a controlling the fluid flow velocity of the first fluid along the micro channel.
