Abstract: The present invention provides a battery powered fan assembly (1) for providing motive force, comprising: An electric drive motor (12); a fan (14), connected to and driven by the drive motor (12) and rotatable about a central axis X, for moving a fluid F and to thereby create a flow thereof; a battery (16), electrically connected to and for powering the drive motor (12); a heat management system (18), for managing the temperature T of the battery (16) comprising: a fluid collector (22), for collecting collected fluid Fc from the flow of fluid F moved by the fan (14); a heat exchange means (20), for exchanging thermal energy between the collected fluid Fc and the battery (16); and a fluid director (24) for receiving collected fluid Fc from said fluid collector (22) and directing said fluid Fc to said heat exchange means (20) for thermal management of the battery (16).

Abstract: A solar receiver and associated components, systems and methods for use with a concentrated solar power plant. The solar receiver including a heat-absorbing solid body, an optical arrangement configured to direct light on to the heat-absorbing solid body, and a heat exchanger cowl proximate the heat-absorbing solid body arranged to provide a flow of working fluid over the rotor. In use, the light from the optical arrangement heats the heat-absorbing solid body which in turn heats the working fluid proximate the heat-absorbing solid body. The heat-absorbing solid body is movable relative to the optical arrangement from a first position to a second position such that the heat-absorbing solid body does not overheat.

Abstract: The present invention includes a novel sintered component (1) and a method of production thereof. The method including creating (100) a plurality of sub¬components (10) using binder jetting additive manufacturing; the sub-components (10) having an outer surface (20) including one or more protruding portions (22, 24) having one or more bonding faces (26) configured to interface with at least one of the one or more bonding faces (26) of a neighbouring sub-component (1) and a recessed portion (28) for defining a cavity (30), in the sintered component (1), between sub-components (10); heating the plurality of sub-components (10) in a first heating step (104); assembling (106) said sub-components (10); heating the assembly of sub-components in a second heating step (108).

Abstract: A solar receiver for converting solar radiation into thermal energy. The solar receiver includes a heat-absorbing solid body, a fluid system to provide a flow of working fluid proximate to the heat-absorbing solid body, and a movement device to move the heat-absorbing solid body such that one or more surfaces of the heat-absorbing solid body are periodically exposed to incident solar radiation. The incident solar radiation heats a portion of the heat-absorbing solid body which in turn heats the working fluid.

Abstract: An integrated battery and cooling system (2) is provided, comprising a plurality of cells (10) and a heat sink arrangement (16). Each cell (10) comprises at least one electrical collector (27) of a first material coupled to a first electrically and thermally conductive electrical terminal (12) extending away therefrom, and at least one electrical collector (27) of a second material coupled to a second electrically and thermally conductive electrical terminal (14) extending away therefrom. The electrical terminals (12, 14) are substantially planar and form respective sidewalls of a series of elongate channels there-between. The heat sink arrangement (16) extends within each channel and is thermally coupled to at least one sidewall thereof.

Abstract: Apparatus and methods for jet impingement cooling are provided. In one arrangement, a fluid channelling structure engages against a target surface to define a flow volume. Fluid is jetted onto the target surface from inlets and is removed via outlets. Flow directing features form a plurality of channels with no straight paths between inlets and outlets. A time averaged flow direction of fluid in contact with each flow directing feature is more nearly perpendicular to a direction of jetting of the fluid from a nearest inlet than parallel to the direction of jetting One or more pairs of the inlets and outlets are such that a majority of fluid jetted onto the target surface from the inlet of the pair will be removed from the flow volume through the outlet of the same pair.
