A nacelle for a wind turbine includes a housing defining an outer wall and a heat transfer assembly embedded at least partially within the outer wall of the housing. The heat transfer assembly includes a heat transfer apparatus having a body with a flow path formed in an outer surface thereof and a working fluid configured to flow through the flow path. The heat transfer apparatus also includes a plate member arranged adjacent to the flow path of the body. As such, the plate member and the outer wall of the housing of the nacelle are configured to conduct heat from the working fluid to ambient air.

A pump system for pumping water for pools or other flow systems including a pump, a motor, an electronic assembly, and a cooling system. The cooling system provides heat transfer from the pump system to the process flow.

A component for a gas turbine engine, comprising: first and second walls; a coolant channel defined by the space between the first and second walls; and a first rib extending between the first and second walls to the end of the coolant channel in a coolant flow direction, such that the coolant channel is bifurcated in the coolant flow direction.

A blower device includes: a fan; a motor rotating the fan; a case supporting the motor; and a heat generating component housed in the case, wherein the case includes: a main body member defining a flow path portion that guides blown air, generated by rotation of the fan, to the heat generating component; and a closing member closing an opening formed on the flow path portion, the main body member includes a fixing portion provided on the flow path portion and fixing the closing member, and the fixing portion is located inside an inner peripheral edge of the opening.

A computing apparatus that is integrated within a flotation module, the system obtaining the energy required to power its computing operations from waves that travel across the surface of a body of water on which the flotation module sets. Additionally, the self-powered computing apparatus employs novel designs to utilize its close proximity to the body of water and/or to strong ocean winds to significantly lower the cost and complexity of cooling their computing circuits.

A system includes a gearbox having an external surface; a fan or impeller constructed to generate a first cooling airflow when rotated; a shroud operative to guide and discharge the first cooling airflow over the external surface and cool the gearbox, wherein at least a portion of the shroud is spaced apart from the gearbox and disposed radially outward of the external surface; and a flow entrainment structure coupled to the gearbox and/or the shroud, wherein the flow entrainment structure is constructed to entrain a second cooling airflow and combine the second cooling airflow with the first cooling airflow to form a combined cooling airflow directed across the external surface to cool the gearbox.
